Potential Vulnerability of Wood Energy Supply Chain Towards 2050 in the French Mediterranean AreaAccording to the Global Warming and The Evolution of Wildland Fire Hazard.


Late studies, among them the IPCC reports published in 2014, 2015 and 2018, underlined a potential decrease offorest areas in Mediterranean context due to the global warming. Climate change can generate different phenomenaon wood resource like the reduction of Net Primary Productivity (NPP), the increase of trees death-rate or theexpansion of wildland fires. All of these events may have a negative impact on the biomass resource used for energypurpose. This assumption, if verified, would have a significant impact on the development of the wood energy supplychain which is usually planned on time range of 25 to 30 years. According to this situation, we propose anEcosystem Based Approach in order to assess the potential areas that are and will be available for the developmentof the wood energy supply chain in all the Mediterranean territories of France. In this frame, we developed threemodels that are integrated into a Spatial Decision Support System prototype. The results show a possible significantreduction of the suitable areas for the development of the majority of the tree species and a possible increase of thewildland fire areas towards 2050 in many areas.

How to Feed the European Bioeconomy in the Future? Climate Change-Forced Shifts in Growth Suitabilityof Industrial Crops Until 2100


The research objective of this study is the sustainable provision of sufficient high-quality biomass from industrialcrops for a European bioeconomy. While much is known about both crop-specific cultivation practices and biomassconversion routes, it remains unclear where and how which industrial crop should be cultivated to meet theanticipated increasing biomass demand in a sustainable way in future. This will become even more relevant in viewof the projected climate change effects on European agriculture. While the prevailing types and distributions ofEuropean marginal land have already been defined, much less is known about shifts in growth suitabilitydistributions. Therefore, the central research question of this study is: ’what are the climate-change-forced shifts ingrowth suitability of selected industrial crops across Europe?’

Converte Project Evaluation of the Potential of Energy Crops in Portugal


Energy crops are dedicated cultures directed to the production of energy in the form of biofuels, electricity or heat.However, those crops also present a dual purpose, since, due to their tolerance to contaminated soils, they are ableto remediate and alleviate soil pollution derived from the disposal of polymetallic agents and other toxic elements.Moreover, as these crops are also suitable for the exploitation of other types of marginal lands (e.g. salinity soils),the risk of land use conflicts due to competition for food and feed is reduced, and they can bring additional revenueto land owners, thus contributing positively to economic growth. Therefore, in the framework of the CONVERTEproject, the aim was to construct and design a georeferenced (mapping) database for mainland Portugal, to identifyland availability for the implementation of energy crops and microalgae culture, and to locate agricultural and forestryproduction areas (including its residues) with potential for its sustainable exploitation (environmentally, socially andeconomically). The productivities forecast as well as bioenergy generation is presented and critically discussed.

Influence of User Behaviour on Emissions from Firewood Stoves


Firewood stoves are widely used in Europe and they may cause high particle matter (PM) and gaseous emissions.Previous research projects highlighted that the user behaviour is an important parameter that influences theemissions of manually operated firewood stoves. To get more information about the impact of the user behaviour onthe emissions of firewood stoves 5 stove ignition and 9 stove refilling methods were tested, including the properstove operation as well as the most common maloperation. The results confirm that the user has a big influence on the emissions of firewood stoves. Therefore, manufacturersshould develop precise manuals that describe the best ignition mode as well as the optimal way of refilling includingthe proper amount of fuel and the optimal fuel condition. These instructions should be specifically adjusted to eachstove. This should best be done by creating a quick-user-guide provided by the stove manufacturer, based onexperimental evaluation performed by the manufacturer.

The Application of Optical Sensor Systems to a Wood Stove


Wood stoves are widely used in domestic heating supply system across Europe. However, wood smoke thatconsists of gaseous pollutants and particulate matter (PM) has been proved to be a significant source of regional airpollution. To optimize the batch wise combustion process and to reduce the emissions from wood stoves, a low-costsensor-based air control system is being developed and tested in this work. Combustion and sensor tests areperformed on an experimental wood stove set-up that is integrated with air staging and an air control system.Comprehensive measurements of key combustion parameters and air pollutants are conducted during the tests.Preliminary testing results show that the signals of soot and tar by the optical sensors agree well with othermeasurements, indicating a promising application of the sensor system to automatically controlled wood stoves.

Connecting Lignin Gasification with Gas Fermentation


Gasification of lignin-rich biorefinery residues, followed by product gas cleaning and anaerobic fermentation, offers apotential to produce higher added-value products such as biofuels and chemicals. However, the integration ofgasification with syngas fermentation is still in an early stage of development. The challenge is to define the optimumgasification conditions for this type of feedstock that allow tar destruction while keeping the H2:CO:CO2 ratio atvalues suitable for syngas fermentation. In this work a lignin rich feedstock is gasified with steam at 780°C inMILENA indirect gasifier, at ECN part of TNO. The product gas after removal of the main impurities, consists of CO,H2, CO2, N2, CH4 and traces of other gaseous hydrocarbons, benzene and H2S. The influence of the obtainedsyngas quality and composition is evaluated in the fermentation process, at KIT. The total efficiency of the processfrom the gasification of lignin to the final high added-value product synthesis is assessed. The fermentation tests arecurrently ongoing and the results will be presented in this work.

Efficient Production of Butyl Butyrate from Lignocellulose-derived Sugars


The efficient production of bulk chemicals (e.g. fuels) is challenging since higher product and to some extendsubstrate concentration affect adversely fermentation cultures by product inhibition. Therefore, ow production ratesrequire larger plants and require extensive handling of process streams with adjacent energy consumption. Thesefactors pose major challenges to fully exploiting biotechnology’s potential in this field. The two key aspects whichneed to be address for improve efficiency of these processes i) In-situ product removal to continuously minimize product concentration in the producing culture is crucial to preventtoxic effects.ii) Innovative process design to optimize reaction rates to fully exploit the potential of a given microbial system.

New Oil Palm Plantations in Papua, Indonesia. Challenges in the Establishment Process.


The establishment of new oil palm plantations in Papua Indonesia, has greatly increased in the last years. Theprocess of new plantation establishment involves land use change, which in many cases is directly related with theloss of primary climax forest. Papua has good climate conditions for oil palm cultivation due to high precipitation andrich in nutrients soils, as well as a large amount of available land; but its remoteness and political situation involvehigher risks and costs for investors. Papua, Indonesia holds abundant biodiversity, being about 50 % of its flora andfauna species native from this island (IUCN, 2008). Forest extension in Guinea Island was above 80 % of its area inthe year 2000 (Beehler and Marshall, 2007). The palm oil industry generates employment opportunities, potential fordevelopment of rural areas, as well as revenue redistribution to society in the form of taxes. On the other hand, landuse change can be responsible for the loss of ecosystem services, loss of natural habitats and carbon emissions.Papua, Indonesia holds very deep and ancient tribal traditions, and its population in general opposes change. Thisreview presents the issue

Use of Biomass Residues for Energy Production: A Comparative Analysis of Energy Potential Between LowHdi Brazilian Municipalities in São Paulo (Sp) and Bahia (Ba)


The study is to assess the availability of biomass residues, as well as the current situation of energy access in twolow HDI cities in Brazil. Aiming to perform this analysis, it will identify the best technological pathways for energygeneration in each case (direct combustion, gasification or anaerobic digestion) contributing both to increase energyaccess and to improve the adequate disposal of residues, contributing to basic sanitation. Besides that, the study willalso try to understand local society’s perception regarding its benefits and challenges. Aiming to do so, it willevaluate the environmental, social and economic impacts of energy conversion from biomass residues (which is arenewable energy) in both municipalities and will check the existing barriers. Furthermore, appropriate policyproposals will be suggested for its implementation.

Fueling Next Generation Hybrid Vehicles with Energy Cane Ethanol.


Anthropogenic global climate change is by far the most threatening phenomenon challenging humankind in thepresent days. The so-called Greenhouse Effect, which has been shown to cause global temperature warming, is dueto different gases, especially carbon dioxide, methane, nitrous oxide, among others. It happens that the main culpritfor the global warming in the atmosphere is the very high concentration of carbon dioxide, produced mainly bycombustion of fossil fuels, such as gas, oil, shale gas and charcoal. As emphasized by renowned researchers,reducing new emissions and capturing the excess of Carbon Dioxide in the atmosphere is mandatory for preservinghuman life in our planet. The objective of this paper is to address the urgency of accelerating the practical use ofapparently matured technologies, which have been developed by the automobile industry, to drastically reduce theuse of fossil fuels in both light- and heavy-weight transportation vehicles. Some of these technologies include afamily of energy-efficient engines that can be used in the next generation of hybrid vehicles powered by low carbonfootprint biofuels, such as sugar cane ethanol.

The Role of Emerging Technologies in Competitive Renewable Hydrogen Production Using AdvancedBiorefineries


Evaluating under the same framework the environmental and economic domains, this work demonstrated theeconomic benefit of one of the renewable hydrogen production schemes proposed, where an acid pretreatment wasused following by a dark fermentation stage working along with a high performance microbial consortia and thesubsequent treat of the liquid effluents to produce biogas for sale as co-product. (APBS scheme). Therefore, the implementation of the proposed APBS design may increase interest in widening the scope ofrenewable biohydrogen production to include other final products within the same process boundaries under abiorefinery scheme in order to improve the economic and environmental balance.

Forest Biomass for Energy Production in Portugal: Exploring Perceptions of Benefits in Terms of ForestFires


This paper focuses on the use of forest biomass for energy purposes, a renewable energy source, which, despitenot being impact-free, presents several advantages and benefits. In particular, Portugal has high raw materialavailability and at the same time has been severely affected in the last years by intense forest fires. In this context,forest ecosystem managers and policy-makers face the challenge of developing effective fire prevention policies andpart of the solution may be found in the use of collected forest biomass for energy generation. In fact, in addition tothe advantages associated with the use of a RES, particularly abundant in Portugal, biomass power plants havebeen presented as a key way of giving economic value to forest residues such as tree branches and foliage and thusencourage silvictors to clean their lands and thus prevent future fires.This study aims to contribute to assess thepotential net benefits from furthering forest biomass energy in Portugal. At the same time, we cross two nationalpolicies, namely energy policy that continues to foster RES, and forest fire prevention policies within forestmanagement. We hope our contribution enriches the debate in Portugal concerning these two topics.

Sustainably Certified Advanced Biofuels - Opportunities and Barriers in the Context of ConvergingBioenergy Sectors


Harmonised standards and certification systems are needed to assess the sustainability of advanced biofuels andfoster their market uptake. This paper identifies opportunities and barriers of sustainably certified production ofadvanced biofuels in in the context of the development of the biobased economy in the EU. To this purpose, weselected three routes of convergence for the development and implementation of common sustainabilityrequirements and certification schemes at the EU level:1. Convergence of solid biomass feedstock markets that might partly shift from other bioenergy markets (heat andelectricity) and non-energy end-use markets towards advanced biofuels;2. Convergence of bioenergy sectors (electricity, heat and liquid transport fuels) by multi-output biorefineries;3. Convergence of geographical boundaries by international trade of solid biomass and liquid biofuels. The research has been conducted in context of the EU H2020 project ADVANCEFUEL that aims to facilitate thecommercialisation of advanced renewable transport fuels to contribute to the achievement of the EU’s renewableenergy targets, and reduce carbon emissions in the transport sector.

Growing Energy Crops for Biomethane Production in the Lusatian Lignite District, Eastern Germany - AContribution to Agricultural Reclamation


Agriculture on reclaimed ground aims to strengthen the efficiency of farms affected by mining and to improve theirviability. However, overall yields remain low to medium and there is hardly any food production and cultivation ofspecial crops on reclamation sites. Therefore, farmers are interested in low-risk production alternatives with goodearnings, such as undemanding, drought-tolerant and fast-growing energy crops like Sorghum or Sudan grass. Inthe present work, the agronomic and techno-economic feasibility of cropping systems based on growing Lucerneand Sorghum as ecologically friendly raw material for biogas production and up-grading to biomethane wereanalysed.

Sustainability Assessment of Innovative Energy Technologies - Integrated Biomass-based Production ofFuel, Electricity and Heat


The transformation of the energy system is of central importance for a sustainable development of Europeancountries. Innovative energy technologies can make an important contribution to increase the share of renewableenergy, for example by using biomass instead of fossil resources. As part of the Helmholtz Initiative Energy System2050 a cross-technology approach for the sustainability assessment of technologies that are essential for theGerman energy transition is developed. The sustainability assessment is based on a detailed modeling of thematerial and energy flows and prospective ecological and economic life cycle analysis (LCA and LCC) including allrelevant upstream as well as downstream process chains. The assessment system includes 10 environmentalindicators recommended by ILCD, 2011, economic indicators such as production costs of fuel and net present valueand different social indicators (e.g. technology acceptance, innovation potential, domestic value added). This paperpresents the results from the indicator-based assessment of the bioliq® process developed at KIT. This processgenerates fuel, electricity and heat from biogenic raw materials.

Application of Different Amendment Practices to Improve the Fertility of Soils in Marginal Lands of CentralSpain


In the Mediterranean region, marginal lands are often unfavorable for agricultural production due to climaticconditions and physical characteristics where limited rainfall, extreme temperatures, low quality soils and steepterrain are encountered. Furthermore, poor land management as well as remote locations in rural areas has led thepopulation to abandon these lands and seek opportunities elsewhere. Within the framework of the European project“Intensify production, transform biomass to energy and novel goods and protect soils in Europe (INTENSE)”; theissue of soil conservation and sustainable increase in food production, novel products for agriculture and newperspectives for European rural landscapes is addressed. The aim of the research work is to improve theproductivity of two marginal soil types by applying different amendment practices within rural areas of Central Spainrepresentative of arid and semiarid areas of the Mediterranean region.

Assessing Options for the Sustainable Intensification of Agriculture for Integrated Production of Food andNon-Food Products at Different Scales (Sustag)


The SUSTAg project identifies sustainable intensification (SI) measures and integrated production systems of dualfood and non-food production. Acknowledging the complex feedbacks through international agricultural markets andthe need to develop and assess region-specific systems and measures, SUSTAg studies SI measures acrossregional, European and global scales in a coordinated framework, assessing environmental and economicperformance of the SI measures.We identify specific SI options in interaction with stakeholders for three regional case studies in Finland, Germanyand Spain as well as for Europe and global analyses. SUSTAg uses global and European projections of futureagricultural markets under climate change and policy scenarios to frame economic conditions in the regional casestudies, in which the different, region-specific SI measures are evaluated with regional modeling frameworks. Weassess the effectiveness of the SI measures with a consistent and flexible SI metrics framework, which has beendeveloped in the SUSTAg project. It allows for considering different aspects of intensification and sustainability.

Clarifying Agents Affect Chlorine Concentration in Biomethane from Sewage Sludge


In this study we report the concentration of chloride and fluoride in biogas and biomethane from sewage sludge inNorthern Italy. Three different plants are monitored based on different upgrading technology. Biogas from sewagesludge is commonly used for thermal and electric energy. However, an alternative exploitation of this biofuel caninclude its upgrading to biomethane. With this regard, chloride can be an issue of technical concern since its levelcan be higher than the maximum allowed concentration, due to the use of clarifying agents in wastewater treatmentplants. Most of upgrading plants do not have dedicated modules for chloride removal, since this is parameter is notcritical for biogas produced from other kinds of biomass.

Food Waste Management in the Mediterranean Hospitality Sector - Pilot Study in Heraklion, Greece


For Greece, with a population of 10.5 million, it is estimated that more than 25 million tourists visit the country eachyear. According to a study conducted in the greater region of Crete by Gidarakos E. et al. (2006,)food waste is themain fraction of the municipal solid waste during the high tourism season, most of it arising in hospitality units. Thisfact provides an excellent opportunity for implementing kitchen based waste prevention systems. Large volumes offood, handled by professionals, with an explicit desire to reduce the amount of food that is thrown away, not just forenvironmental, but mostly for economic reasons. In order to reduce the amount of food waste, it is essential to knowwhere, why and how much food is discarded. For this aim, the “ResourceManager-Food” develpoped at theUniversity of Stuttgart is applied in 6 pilot hospitality units in Heraklion, Crete, Greece.

Esters Production by Yeasts Using Tequila Vinasses as a Substrate


Tequila is the most recognized Mexican distillate around the world. Production and consumption have grownsignificantly in the last five years, reaching 271 million litters in 2017 (CRT, 2017). According to the TequilaRegulatory Council (CRT), this industrial activity generates significant amounts of solid and liquid waste such asbagasse and vinasses, which constitute an environmental problem, particularly the second one. Therefore, a goodalternative for these residues is obtaining value added products in fermentative processes from metabolism ofmicroorganisms, such as esters (2-phenyletylacetate, ethyl acetate, ethyl acetate, isopentyl acetate, etc.) like aromacompounds used in several industrial applications. In this study, several yeasts species (Wickerhamomycesanomalus, Candida glabrata, C. utilis, C. apicola, C. parapsilopsis, C. guilliermondii, Kluyveromyces marxianus andP. kluyveri) were studied with two different chemically defined media and tequila vinasses as culture media, whichpresented differences in aroma compounds accumulation, determined by the yeast species. In conclusion, tequilavinasses are suitable to produce industrial metabolites such as esters.

Endogenous Bio-Waste and By-Product Streams Valued as a Resource for Fermentative HydrogenProduction


Recently, the European Union (EU) has taken steps to counteract the negative impact of carbon emissions withmore restrictive legislation for waste treatment and disposal. One example is the 2018/851/EC Directive on wastethat restricts landfilling and encourages the separate collection of bio-waste [1]. This directive points to the efficientand rational utilisation of natural resources while boosting the use of bio-waste as resource and promoting theprinciples of the circular economy. Accordingly, this study evaluated the suitability and performance of darkfermentation (DF) as conversion solution for hydrogen (H2) production from agro-food wastes and by-products.

Production of Carotenoids and Biosurfactants by Gordonia Alkanivorans Strain 1B Using Food Residuesand Derivatives


Through different bioprocesses, microorganisms, such as yeasts and bacteria, ferment and transform residuestreams into high added value products, such as carotenoids and biosurfactants. Gordonia alkanivorans strain 1B isone of such bacteria, capable of consuming and transforming many types of residues. It is mostly known for itsbiodesulfurizing ability and it was recently described as a producer of both carotenoids and biosurfactants.In previous works, strain 1B has been cultivated on different sugar rich alternative carbon sources. However, it wasshown, that in order to promote surfactant production, the microorganisms should be exposed to inducing factors,such as lipids and alcohols. This work focusses on valorisation of residues from the restaurant and food industry,and derivatives from their processing, by using them as carbon sources to grow the bacterium and producecarotenoids and surfactants.

Spatial Modelling of the Organic Waste Generation by Private Households


Bioeconomy is the future driving force for our society, economy and ecology. A sustainable and successfulbioeconomy relies on the utilisation of all kinds of different biomass resources, especially resources with less value.Avoiding the food-feed-fuel- and fibre-controversy, it is crucial to also use organic waste. The aim is to spatiallymodel the generated amount of organic waste from private households in the German Federal State ofBaden-Württemberg. The model shows the spatial distribution of generated organic waste and thus giving guidanceto stakeholders who need the information for utilisation or treatment of the waste.

Biomass Logistics Planning: Are There Gains in Integrating Chipping and Transportation Operations?


This work addresses the routes planning for three distinct types of vehicles and its purpose is to integrate chippingand transportation operations in the biomass supply chain. It specifically relates to the synchronisation of vehiclesinvolved in wood chipping and transportation when these operations are combined at the roadside of forest sites(called "hot systems"). At residue piles, chipping machines process and load the material directly into chips-movingtrucks, so they are required to be present at the pile during the entire chipping process. Furthermore, as chippingmachines are non-autonomous vehicles, they need to be transported between residue piles by auxiliary vehicles.A mixed integer programming approach is developed, along with a matheuristic solution method for solvinglarge-scale instances. For a baseline instance, the synchronisation aspects tackled in this problem allowed forsignificant gains when compared to the company’s current planning approach. Furthermore, the proposed approachcan enhance planning and decision making processes by providing valuable insights about the impact of keyparameters of biomass logistics over the routing results.

Optimisation of French Energy Catch Crop Production in Double Cropping Systems for On-Farm BiogasUse


Double cropping systems including energy catch crop represent an innovative way to achieve ambitious targets ofFrench energy transition mainly for on-farm bigas use. The purpose of Opticive program was to improve croprotation management of these innovative cropping systems for food/feed and non food use. Different parameterswere assessed for farmers decision making : target yield and production costs. Both innovative cropping systemsand analytic experiment were carried out to assess technical, economical and environmental parameters. From 6 to8 tDM/ha and 110 €/tDM of complete production cost, energy catch crop production in double cropping system seemto be a good adaptation strategy for French farmers but has to be improved to decrease yield variabillity.

Behavior of Torrefied Pellets Versus Fresh Woody Pellets in a Fixed-Grate Reactor: Comparison ofCombustion Parameters and Fouling and Slagging Tendency.


Torrefaction is a thermal decomposition process of biomass carried out at temperatures in the range 230ºC-300 ºC,atmospheric pressure and inert atmosphere. The upgraded fuel presents higher low heating value and lowermoisture content. It is also less fibrous, which improves milling, and more stable with respect to biologicaldegradation, facilitating its storage. Combined use of torrefaction and pelletization allows to obtain a fuel with betterphysic-chemical properties that could be more advantageous for utilization in energy production.Although the changes in the characteristics of the fuel attained by means of torrefaction seem beneficial, it isnecessary to evaluate how this process affects combustion. Particularly, the behavior of ashes regarding fouling andsintering.In this paper, it is compared the behavior in combustion of torrefied and non-torrefied pellets prepared fromvineyards and olive pruningusing the results of the projects MHLPelet (ENE2015-68809-R) and SteamBio (GA No:636865 SPIRE-02-2014). In both projects, controlled combustion tests in an experimental fixed-grate reactor havebeen carried out, varying air conditions.

Detailed Experimental Investigation of the Spatially Distributed Gas Release and Bed Temperatures inFixed-Bed Biomass Combustion with Low Oxygen Concentration


This work is focused on the experimental investigation of the fixed-bed behaviour in biomass combustion with a lowoxygen concentration. The low oxygen concentration is obtained through low primary air ratios or flue gasrecirculation, reducing bed temperatures and therefore its inorganic emissions. The facility is usually operated withsoftwood chips with a low moisture content, 30 kW fuel power, a primary air ratio of 0.22 and with and without fluegas recirculation, investigating as well variations of these parameters. All relevant components of the released gas,including gaseous species, light tars, heavy tars and water, are measured with several techniques. The fuel bedtemperature distribution is also measured. The distribution in different zones of the thermochemical conversionprocess inside the fuel bed are analysed and the influence of process conditions such as flue gas recirculation,partial load or a higher moisture content is discussed.

Development of a fuel flexible condenser coupled to a small-scale combustion technology based onextreme air staging – CFD based development and operation experiences


Condensing biomass boilers gained increasing importance in the residential heating sector within recent years butthe fuels for residential condensing biomass boilers are almost exclusively restricted to high quality wood fuels(namely pellets and wood chips). As it is a dedicated aim of the EC and the EU member states to promote theutilisation of biomass fuels for energy production as a measure for CO2 emission mitigation and since high qualitywood fuel resources are not available in high volumes in many European regions, the fuel spectrum to be applied inresidential biomass combustion systems must be broadened in order to cover the rising fuel demand while avoidingincreasing fuel prices in future. Moreover, measures to further increase the thermal efficiency of residential biomassboilers are urgently required to use the available biomass potentials as efficiently as possible and to keep themcompetitive in comparison to fossil fuel based systems, also in terms of energy labelling.

Smart Logwood Boiler - A holistic approach for improving the efficiency of residential heating systems


Modern logwood-based heating systems typically consist of a configuration including a logwood boiler, a bufferstorage and solar thermal collectors. The aim of the work presented was to develop a holistic model-based controlstrategy for these heating systems that maximizes the utilization of solar yield. This should lead to a higher overallefficiency and simultaneously decreased pollutant emissions. The developed control strategy uses forecasts for thesolar yield and the load demand of the residents as well as mathematical models of the logwood boiler and thebuffer storage to determine an optimal operating strategy for the entire heating system. The control strategy alsolearns typical patterns in the user behaviour and adapts the optimal operating strategy accordingly. The application of the new control strategy at a test system including a commercially available logwood boiler with anominal capacity of 28 kWth resulted in a significantly improved efficiency of the system. During a four-day test run 8% more solar yield was achieved and the buffer storage losses were reduced by 14 % compared to the operationwith a typically applied conventional control strategy.

The Potential of Ionic Liquids in the Biorefinery Concept


The current development of lignocellulosic biomass processing in the frame of the biorefinery concept requires moreinnovative technologies, which would allow more sustainable valorisation of this feedstock. The main challenge liesin the deconstruction of macromolecular structure of biomass into individual fractions, namely cellulose,hemicellulose and lignin for further upgrade towards biofuels, biochemicals and biomaterials. Biomass processing,with ionic liquids (ILs) is one of the most promising green technologies due to versatility of ILs to convert thisbiomass into a wide range of aforementioned commodities.

Economic and Environmental Evaluation of Biofuels for Future Sustainable European Aviation


Decarbonization of the transport sector as proclaimed in the COP 21 targets requires the transition from fossil torenewable energy sources. Aviation, shipping and heavy duty transportation are expected to continuously rely onliquid fuels. Biofuels can replace a large share of fossil fuel in these sectors. However, the usage of biofuels withintransportation is only reasonable with significantly reduced Greenhouse gas (GHG) emissions compared to fossilfuels and lower GHG abatement costs compared to other decarbonization technologies (e.g. Power-to-Liquid,hydrogen, electric mobility etc.). A detailed discussion of biofuels prospects for future European aviation shall bepresented. Different biofuel production paths are compared and analyzed in terms of technical potential andchallenges, fuel production costs, GHG footprint and GHG abatement costs. Based on the results the followingsuperordinate questions are addressed:• What share of the European aviation demand can be covered by biofuels?• What types of biofuels are required and certified for aviation?• How to compare GHG abatement potential and costs with other GHG reducing options?• What technical challenges a

Evaluation of the Vocs Emitted by the Combustion of Rice Straw


VOCs (Volatile Organic Compounds) include a large number of classes of compounds, for example CFC, aliphaticand aromatic hydrocarbons, terpenes, aldehydes, ketones, alcohols, etc. Such a wide variety of compounds impliesvarious harmful effects both for humans (VOC-TOX) and for the environment (VOC-OX, VOC-CLIM, VOC-STRAT).One of the main anthropogenic sources of VOCs is universally recognized in the processes of controlled oruncontrolled combustion of agricultural waste. This study is aimed to perform a qualitative analysis for theidentification of VOCs emitted by the burning of rice straw biomass. The biomass has been shredded andcharacterized to determinate its chemical and physical characteristics before the combustion and the monitoring ofthe emission. The VOC were sampled following UNI CEN/TS 13649 (2015) method by self-made ACF adsorbenttraps suitable for subsequent thermal desorption. Subsequently VOC were determined by thermal desorption system(Markes TD 100-xr) and a triple quadrupole gas chromatography-mass spectrometry (GC-MS) system Agilent (GC7890A and MS/MS 7000).

Environmental Trade-Offs Associated with Bioenergy from Agri-Residues in Sub-Tropical Regions: a CaseStudy of the Colombian Coffee Sector


Global coffee production generates a vast amount of residues and waste along its value chain, posingenvironmental, health and economic challenges to coffee farmers. Improving the utilization of crop residues, likecoffee stems, in small-scale bioenergy applications addresses several Sustainable Development Goals as it wouldsupport environmental, economic, and social co-benefits if current rural practices were replaced. To evaluate theenvironmental benefits of such bioenergy integration requires a comprehensive assessment at the coffee supplychain level in relation to potential other uses and displacement of the biomass. Using a life-cycle assessment approach, this work evaluates the environmental sustainability of the gasification ofcoffee crop residues (stems) to produce decentralized low-carbon energy, within the context of the Colombian ruralcoffee sector. This LCA study highlights the importance of evaluating the environmental trade-offs of bioenergysystems for power and heat generation in rural areas, by investigating the impact of different counterfactualscenarios on the environmental sustainability of the bioenergy system.

Production of a Combustible Fuel Pellet from the Solid Fraction of Separated Anaerobic Digestate withAssociated Phosphorous Partitioning


The production of a combustible pellet from digestate not only provides a second fuel from the anaerobic digestionprocess, but also partitions phosphorous into a nutrient dense form (ash) that can be easily transported away fromhigh risk areas to areas of lower environmental concern. The aim of this paper is to investigate the effectiveness ofsuch a system in terms of overall energy balance and environmental impacts.

Intensify Production, Transform Biomass to Energy and Novel Goods and Protect Soils in Europe;INTENSE


World food production must increase by 50 % within 2050 if the rising population, estimated to reach 9.8 billioninhabitants, shall be fed. This will only be possible if available land can be employed for food and biomassproduction. Set-aside land must be recuperated and the productivity of marginal soils must increase. Polluted soilsneed to be ameliorated and phytomanaged to produce valuable biomass, e.g. for the bio-energy sector, inbiorefineries (biosourced chemistry), for biocatalysis, essential oils, fibers and other raw materials. At the same time,soil rehabilitation must be accomplished, contributing to remediate pollutant linkages, soil multi-functionality andassociated ecosystem services. Such a paradigm change will give new perspectives for European rural landscapes.Thus, future land use will embrace efficient and sustainable production and utilization of biomass for improvedeconomic, environmental and social benefits, and boost ecosystem services.

Hydrothermal Liquefaction of Biomass: Effect of Addition of Metals (Fe, Ni And Al) on the Bio-Crude Yieldand Quality.


Hydrothermal liquefaction is a promising process for the production of liquid biofuels. One of the major drawbacks ofthe HTL bio-crude is its high oxygen content. To produce bio-crude with higher quality in this work the use of metalcatalysts is investigated. Ni, Fe and Al are added to the reaction mixture in order to improve yield and quality ofbio-crude. The hypothesis is that these metals produce hydrogen in situ allowing hydrogenation reactions into theHTL reactor. The produced bio-crude presents, in fact, higher yield and lower oxygen content.

Characterization of the Aqueous Fraction from Hydrothermal Liquefaction of Lignocellulosic BiorefineryCo-Product


In a 2nd generation ethanol plant, lignin is not fermentable and, consequently, a large amount of a very wetlignin-rich stream is produced, which in the current management practice is dried and co-burned for heat and powergeneration.The aqueous phases resulting from the subcritical, batch hydrothermal liquefaction (HTL) of LRR from an advancedlignocellulosic ethanol biorefinery were characterized to determine their organic and inorganic quantitativecompositions.An experimental plan with three factors and two levels was carried out by varying reaction temperature (300 – 370°C), residence time (5 – 10 min) and biomass-to-water mass ratio (10 – 20 % w/w, dry basis), and the influence ofthese controlled variables on multiple measured outputs was assessed, notably yields of each product and carbonrecovery.The aim of the work was to support with novel data the development of strategies for the recovery of carbon from theaqueous stream originated during the hydrothermal conversion of organic feedstock, by partly filling the knowledgegap in the literature related to the aqueous phases from this thermochemical process.

Modelling of The Integration of Htl with Ccs/ccu for the Production of Drop-In Biofuels


The production of drop-in biofuels through hydrothermal liquefaction (HTL) of forestry residues is modelled in AspenPlus. A generic approach based on experimental data on feedstock and products is developed for the estimation ofthe energy balance in the reactor, which can be extendable to other types of biomass. The process integrationassessed in this study is based on the trend towards systems with higher level of electrification in the context ofintegrated energy systems. Techno-economic analyses are performed to assess the integration of HTL with carboncapture and storage (CCS) and/or carbon capture and utilization technologies (CCU) for combined HTL andelectrofuels production (electro-HTL). Heat integration will be implemented to explore the possibilities of excess heatproduction from the process for district heating applications. Different scenarios will be studied based on electricityprice/availability and desired carbon emissions from the process.

Nmr Analysis and Quantification of Organic Compounds in Aqueous Side Streams from ThermalConversion of Biomass with Water


Steam explosion (SE) and hydrothemal liquefaction (HTL) produce aqueous side streams that contain significantlevels of water-soluble organic chemicals, e.g. furfural, organic acids, alcohols and phenols. These compounds are apotential resource to be recovered for added value from the conversion process. Quantitative analysis of highlywater soluble organic compounds can be challenging. Using a metabolomics approach, we have established a NMRprocedure that provides a quantitative determination of all major dissolved organic compounds from HTL and SEbiomass conversion directly in the aqueous phase. The method is rapid and simple, and very suitable for evaluatingthe potential for recovering additional biobased products from the aqueous side streams.

Biorefinery Process for Hydrothermal Liquefaction of Phaeodactylum Tricornutum


Nowadays, there are an increase in energy demand which requires replacement of a high portion of fossil fuels withgreen energy supplies and technological development. Microalgae are an interesting alternative source for biofuelproduction due to their rapid growth rate and their ability to accumulate carbohydrates and lipids. One of the difficulties is that the 50% of the required energy for the process is consumed in distillation and drying.This problem could be solved if wet-algal biomass can be directly utilized for biofuel production. Hydrothermalliquefaction (HTL) is carried out in a water medium at moderate temperatures and high pressures. The aim of this work is to optimize the HTL of Phaeodactylum tricornutum in order to obtain a biocrude of high yieldwith low nitrogen and oxygen contents. The detailed study of the cultivation phase is essential to select the adequatemicroalga strains to produce the advanced biofuels. In this sense, the culture conditions for that strain wereoptimized previously.The HTL was carried out controlling temperature, pressure and stirring.

Optimisation of Nannochloropsis gaditana hydrothermal liquefaction to upgrade biocrude


The objective of this work was to optimize the conditions for obtaining a high quality biocrude through a process ofHTL starting from biomass of Nannochloropsis gaditana. Temperature (T), time (t) and slurry mass concentration(C) were the main factors selected to optimise the HTL process through three different responses, i.e., biocrudeyield (maximise) and oxygen and nitrogen content in biocrude (minimise).

Optimisation of Chlorella Vulgaris Hydrothermal Liquefaction for Bio Crude Upgrading


The aim of this work were to evaluate bio-oil yield and quality through HTL process from Chlorella vulgaris indifferent reaction times under non-catalytic conditions and to evaluate N and O reduction in bio-oil product undercatalytic conditions using 5wt% of Ni/Al2O3 at similar reaction times. Experiments were carried out at 320ºC,pressure of 10 MPa, reaction times of 10, 30 and 60 min and 10 % of slurry concentration. Comparing catalyst and non-catalyst results for HTL process from C. vulgaris, the highest yield of bio-oil wasobtained for the 10 min reaction time, and the results were similar in both cases, (cat. 32.50±0.15 wt% and non-cat.31.01±0.38) with higher yield for catalyzed reactions. However, bio-oil composition was improved in presence ofNi/Al2O3 with a decreased in nitrogen and oxygen content, obtaining higher HHV in the range of 28-31.7 kJ/mol.Finally, short time reaction under catalytic conditions produce higher yield for bio-oil production in HTL process.

Results of the Two-Year Rebaf Project: How to Exploit Biomass from River Maintenance


This paper discusses activities and results of the REBAF project: a two-year Italian regional research project. Theproject focused on the energy conversion of recovered biomass residues from river, canals and basins maintenanceactivities. In particular, rivers and channels of the municipality cluster Unione Terre d’Argine (UTA) was the casestudy of the project. In the REBAF project innovative pathways for the exploitation of grass and woodsy biomasseswere investigated. Gasification and pyrolysis were the key technologies for biomass conversion into energy. Themost important result of REBAF project is the gasification biochar utilization as soil improver and pyrolysis char usedas filler in building materials. These are two valuable Carbon Capture and Storage (CCS) processes based ofbiomass conversion technologies that can be easily applied in the green maintenance environment.

Efficient Preservation of Technically Dried Wood Chips - A Comparison Between Outdoor Storage with AFleece Cover and Storage in a Storage Building


The storage of wood chips is an important step in the biomass supply chain. In the current research project, weinvestigate i. a. different methods of storing technically dried wood chips. The research question of our presentworking package is, if storing technically dried wood chips outdoors with a fleece cover leads to the same resultsconcerning fuel quality and dry matter loss, than storing in an expensive storage building without fleece. As a fieldtrial, two piles of technically dried wood chips with a volume of 80 m³ each were set up. One pile was storedoutdoors, covered by a fleece and the other one indoor as a reference. In an additional trial, we installed alarge-scale laboratory experiment with a custom-built sprinkling system, to investigate the rainfall retention capacityof the fleece under controlled conditions. First results promise a retention rate of 60–70 % for medium to heavyprecipitation events.

Co-Firing of Two Torrefied Pruning Residues with Coal in a Pulverized Fuel Pilot Plant


At present, solid fuels such as coal provide an important amount of the energy consumed worldwide and biomass ispresented as a renewable substitute of the former. Nevertheless, there are still some sources of biomassunderutilized due to several constraints such as logistics. Agricultural prunings are one of these biofuels andtorrefaction is presented as one of the alternatives to solve some of these logistic issues. Regarding the combustiontechnology, co-firing biomass with coal in existing pulverized facilities is a promising way to reduce GHG emissionswithout huge economic impacts due to plant modifications. The main objective of this research was the assessmentof the behaviour of two different agro-residues:1) olive tree and 2) vineyard prunings, at raw and torrefied conditions,in order to determine if any drawbacks may arise when using torrefied material in a facility not initially designed forthis purpose.

Co-Combustion of Residual Forest Biomass with Sludge from the Pulp and Paper Industry in a Pilot-ScaleBubbling Fluidized Bed


Distinct types of residual forest biomass derived from eucalyptus (including pellets made from eucalyptus bark, smallbranches and leaves) were mixed with varied mass percentages of primary and secondary sludge from the pulp andpaper industry, and its co-combustion behavior characterized in a pilot-scale bubbling fluidized bed. The mainobjective was the determination of sludge addition influence on the overall process and on the composition of theexhaust gases, with emphasis on chlorine emissions, namely present in the solid phase (fly ashes) and in thegaseous phase (HCl), and NOx emissions. The co-combustion process of residual forest biomass with primary sludge (up to 5%wt) and secondary sludge (upto 10%wt) was successfully demonstrated as a valid energy valorization option for the sludge. Except specific cases,no significant emissions increase of NOx, CO or HCl were found with the addition of sludge. In fact, HCl emissionsdecreased due to an increase in the chlorine retention in ashes, which can be related to the high calcium contentpresent in the sludge.

Reduction of Ash-Related Problems in Large-Scale Biomass Combustion Systems Via Resource EfficientLow-Cost Fuel Additives


The incineration of waste wood is very often associated with ash-related problems (deposits, slagging andcorrosion). This leads to short maintenance intervals, which result in significant power generation losses and highdowntime costs. To avoid these problems, additives can be used, with particularly cost-effective additives being ofgreat interest.

Pm - O2 Correlation in Combustion Processes in Pellet Stoves and Boilers


In recent years, problems of emissions and pollutions in cities and rural areas are increasing attentions. In order toreduce the level of pollutions, regulations and labels are promoting renewable fuels and burning appliances with highefficiency and low emissions. To develop a combustion able to minimize emissions as much as possible, it isnecessary know which factors influence emissions, in particular carbon monoxide (CO), nitrogen monoxide (NO)and particulate matter (PM).This research analyzes relations between PM and air excess, indicated by O2 content in the flue gases, in fivedifferent pellet stoves. Each stove differs from the others in terms of burning pot geometry, burning pot size andburning power.In all combustion processes analyzed, a relation between PM measured and O2 content in the flue gases is noticed.There is an exact O2 percentage in the flue gases that minimizes PM emissions for each stove. This optimal O2percentage can change when the stove configuration changes.

Recovering Furfural from the Aqueous Waste Stream in Arbacore(Tm) Brown Pellets Production


Large-scale production of steam exploded Arbacore(TM) pellets gives a high-volume liquid side stream containingorganic components of value for the chemical industries. The combination of producing Arbacore(TM)pellets,recovering the organic chemicals and utilising an energy-rich gas phase for process heat, makes the overall concepta biorefinery, with a very high level of utilisation of all feedstock fractions. Here, we determine amounts, compositionand optimal recovery process of the organic chemicals present in the aqueous side stream from the pelletsproduction. Understanding the reaction mechanisms and establishing reaction pathway descriptions for conversionof hemicellulose into furfural will enable optimisation of the total process in terms of feedstocks, yields, processenergy and recovery options. Improved sustainability compared to not recovering the organic Chemicals can also beevaluated.

Selective CO, H2 and CO2 Consumption by B. Methylotrophicum during Syngas Fermentation


Lignin-rich biomass generated as residue in second-generation bioethanol plants is a very important renewablematerial that can be valorized as process by-product by gasification. This thermochemical process converts theresidue in a gas mixture (syngas) mainly composed of carbon monoxide (CO), hydrogen (H2) and carbon dioxide(CO2), being nowadays this syngas mostly combusted for energy purposes. However, the gasification of lignin-richresidues also enables all carbon to become available for the generation of valuable compounds. Syngas can befermented by autotrophic acetogenic bacteria which have the ability to fix gaseous inorganic carbon (CO, CO2),converting it to organic compounds. The Wood-Ljungdahl pathway, the most efficient non-photosyntheticmechanism of carbon fixation, allowing the direct conversion of the fixed carbon to acetyl-CoA. This platformmetabolite can then be converted by the cells to further reduced products, such as alcohols and acids for theproduction of biofuels and chemicals.

Role of National Fossil Fuel Comparators in the Nominal Emission Savings through Bioenergy under theRed - Case Study in Six Eu Countries


As part of the energy transition efforts, most bioenergy policies are strongly driven by the ambition to reducegreenhouse gas (GHG) emissions and substitute fossil fuels. The challenge here is to properly select the fossil fuel“baseline” comparators for each form of bioenergy for any given national context. Based on existing literature as wellas data and experiences gathered within EU co-funded research projects the paper presents the methodologicalapproach for discussing the effect on nominal GHG emissions savings due to bioenergy under RED rules taking intoconsideration the national fossil fuels comparators instead of EU-average ones. The paper assesses this effect foreach sector (electricity, heating/cooling, transport) separately without trying to compare them. The paper shows thatproject-specific and/or national fossil fuels comparators in the calculation of nominal GHG emission savings frombioenergy can have a more stimulating effect than generic European Union (EU) comparators.

From Conventional to Renewable Natural Gas: Can We Expect Climate Benefits in the Near Term?


Introducing a fraction of renewable natural gas (RNG) into the conventional natural gas (CNG) network is a strategyfor which no scientific data on GHG mitigation potential are currently available. This research examines the timing ofatmospheric benefits and potential GHG savings, including the related uncertainty, associated with the substitution ofCNG with RNG sourced from various feedstocks (harvesting residues, mill residues, and salvaged trees) in threeforested regions along the Canadian gas line network. We calculated the GHG balance of the RNG scenariosrelative to a base-case scenario or counterfactual, which encompasses the use of CNG and different pathways forthe fate of woody debris (piled and burned, decay on site, and decay in landfills).

Do the Non-Co2 Climate Forcers Offset the Co2 Benefit of Biomass Use for Residential Heating?


The paper aims to evaluate the CO2-equivalent (CO2eq) emission factors (EFs) associated with experimentallydetermined CH4 and the other non-CO2 climate forcers from heat production without fossil fuels in residentialbiomass heating appliances ( 35kW). In literature there are not many studies reporting CO2-eq EFs, especially inassociation with experimentally obtained methane EFs, from residential biomass heating appliances. The CO2eqemissions emitted by these appliances are then put in the context of the overall greenhouse gas (GHG) emissions ofLombardy region in northern Italy where there is a widespread use of woody biomasses for residential heating.

Climate Change Effect on Crops and Biorefineries


The main crops cultivated worldwide are: corn, rice, sugar cane & wheat. These could be primarily used for food, butalso, in a biorefinery context and Bioeconomy future to produce other valuable products, including bioplastics,bioenergy and fertilizers. The climate change impact of such “crop and biorefinery” systems have two sides: on one hand the systems netCO2eq emissions are positive, contributing to the increase in atmosphere CO2 concentrations, therefore to climatechange; but, on the other hand, the climate change could also impact the crops yield and therefore the biorefineryproducts yield and sustainability. At a first approach sugar cane and energy cane will be the first case study in Brazil.

Sugarcane Straw Recovery: Potential of Climate Change Mitigation in Brazil


This study aimed to estimate the potential of additional bioelectricity production from sugarcane straw in Brazil andits potential for climate change mitigation. Brazilian electricity matrix is mostly renewable, depending mainly onhydroelectric plants. In recent years, this dependence became critical due to changes in rain seasonality. During dryperiods in Brazil, the level of water reservoirs decreases and there is the necessity of electricity from other sources.Sugarcane bioelectricity is a reliable source during dry periods and has several advantages such as low greenhousegas (GHG) emissions and low losses during transmission. Another option for dry periods is the activation ofthermoelectric plants driven by natural gas. However, such plants have higher emissions of CO2eq per kWhproduced compared to sugarcane bioelectricity. Currently, sugarcane sector is producing bioelectricity mostly frombagasse, but straw (sugarcane tops and leaves) presents a huge potential of additional electricity production.

Renewable-Derived Plastics: an Innovate Greenhouse Gas Removal Technology


Renewable-derived plastics, defined here as bio-based non-biodegradable plastic materials, are analysed as a GGRtechnology with a climate benefit potential. Renewable-derived plastics represent a biogenic carbon storage in stablechemical structures similarly to biochar or soil carbon storage. Up to 12,000 million tonnes are expected to be wasteplastics in landfills by 2050, which represents a significant carbon pool. The implications of renewable-derived plasticextensive production would affect not only the chemical industry but also the way we manage the disposal of plasticwaste. The preliminary results indicate that they have a moderate potential for GGR compared to BECCS/Bio-CCSand others common GGR technologies. However, the proposed GGR technology has a similar performancecompared to other innovative technologies such as biochar and SCS. For doing so, further study is needed toimplement this GGR technology into Integrated Assessment Models (IAMs).

Environmental and Economic Assessment of Cynara Cardunculus to Local Bioenergy Production underRainfed Conditions in the Context of Climate Change Impact


Most climate change scenarios consider the Mediterranean region as one of the most vulnerable region in the worldwith expected higher temperatures and lower rainfall trends. Local production of energy crops in marginal conditions(which do not compete with food crops)could make sense to improve local development and prevent ruraldepopulation, provided they have lower environmental impacts and can be produced at a reasonable cost. In thiscontext, dedicated energy crops for producing local feedstocks in a sustainable way and that are well adapted toMediterranean conditions, could play an important role in mitigating climate change. This study assesses the carbon footprint analysis and an economic assessment along the life cycle of the Cynaracardunculus (cardoon) for biomass used as feedstock to produce biomass pellets for heat generation in domesticboilers. Results from this research study could support future policy decisions on local biomass production, based on theexpected GHG emissions savings and economic profitability of biomass pellets production to domestic heat purposeat local level.

Biomass, Coal and Carbon Debt: Exploring a Recent Dynamic Lifecycle Analysis of Wood Bioenergy


In a recent paper, Sterman et al (2018) describe a simple model to give rapid, indicative results of the carbondynamics of biomass production and use. In this work we first replicate the results obtained by Sterman et al. in arebuilt version of their model, we then extend their analysis to incorporate a number of revised assumptions andparameterisations, which we argue are closer to real-world biomass supply chains.

Enzyme-Catalyzed Synthesis of Glycerol Carbonate from Glycerol and Carbon Dioxide


The present study dissolved carbon dioxide in bicarbonate using carbonic anhydrase and converted it into dialkylcarbonate by adding methyl iodide to the bicarbonate solution. Glycerol was then added to the dialkyl carbonate, andglycerol carbonate was prepared using lipase. Finally, these steps were connected to construct a glycerol carbonatesynthesis technology using renewable carbon dioxide and glycerol. Highlights1. A convenient enzyme-catalyzed method for the synthesis of glycerol carbonate from CO2 and glycerol wasestablished, and its reaction mechanism was estimated. 2. The entire process from gaseous CO2 to bicarbonate, DMC and GC synthesis was demonstrated step by step byHPLC analysis. 3. The mechanism on a single port is expected to occur in three steps by carbonic anhydrase and lipase catalysis toproduce the glycerol carbonate from CO2 and glycerol.

Assessing the Feasibility of Hydrothermal Carbonisation (Htc) for the Treatment of AD Digestate


This work studies the application of hydrothermal carbonisation (HTC) as a waste treatment for anaerobic digestiondigestate through the means of a flexible process model. HTC converts biomass into a solid carbon-rich product,hydrochar. It is particularly suited to wet biomass as no feedstock drying is required, offering large energy savingswhen compared to pyrolysis and other thermal treatments.A process model has been developed and simulated with varying temperature and residence times. Optimisation ofthe process depends on the desired outcome as an increase in process severity lowers the yield of hydrochar, butincreases its energy content. There is a trade-off between the increased income from a greater yield and the highermarket value that a higher energy density attracts.Following on from the process model, life cycle assessment and techno-economic analyses will be carried out,considering hydrochar markets in energy, agriculture and activated carbon.

Hydrothermal Carbonization of Lignocellulosic and Lipidic Wastes Mixtures


Biomass wastes are very abundant endogenous fuel resources, with the potential to decrease fossil fueldependence and increase energy provision and global energy supply. Nevertheless, these wastes present lessfavorable characteristics, such as high moisture contents, low energy density and in some cases low productivity,resulting in high transportation costs and a high processing cost. These properties often hinder their application inthermochemical conversion processes such as combustion, pyrolysis or gasification. Hydrothermal carbonization (HTC) appears as a suitable technology for the conversion of raw materials with highmoisture and mineral contents, transforming them into densified solid fuels with low mineral content and highcalorific value, without resorting to the drying of the material. This work was developed with the purpose of evaluatingthe applicability of the HTC process to mixtures of two very abundant waste streams: lignocellulosic biomass andwaste cooking oil (lipidic waste). Different parameters of the HTC process were studied, namely temperature,working volume, biomass:water ratio, and mixing proportion of the two wastes.

Effects of Product Recovery Methods on the Yields and Properties of Hydrochar from HydrothermalCarbonisation of Microalgae


This study aims to systematically investigate the effects of product recovery methods on the yields and properties ofhydrochar from hydrothermal carbonisation (HTC) of microalgae. After HTC under batch conditions, algal hydrocharparticles that retain majority of lipids are suspended in the mixture of bio-oil and aqueous phase. The completeseparation and accurate quantification of the hydrochar is of primary importance in terms of both product yields andproperties. There are mainly two different product recovery methods for separating hydrochar from aqueous phase,used by the researchers. Here, we evaluate the effects of the two product recovery methods on the yields andproperties of hydrochar produced from HTC of microalgae under identical process conditions. The hydrocharparticles produced from both methods would be analyzed for elemental carbon, ash content, SEM, BET surfacearea, and FTIR analysis. To the best of our knowledge, this is the first study to compare the product recoverymethods and their effect on the yield and properties of hydrochar from HTC of algal biomass under identical processconditions.

Influence of Hydrothermal Carbonisation on Combustion Properties of Biomass


Seven high moisture, residual biomass feedstocks were pre-treated by hydrothermal carbonisation (HTC). With aidof fuel analysis data, thermgravimetric analysis and common fuel indices the impact of HTC on fuel propertiesrelevant for comubstion is assessed. HTC was found to have a positive impact on energy density, ecpectedcorrosion tendency, ash melting temperature and expected fine particle emissions. On the other hand, HTC wasfound to increase fuel-N content (and thereby possibly NOx emission) and yield fuels with decreased reactivity asindicated by thermogravimetric experiments.

Conversion of Waste Products in High-Quality Products Via Hydrothermal Carbonization


Our group aims to optimize the HTC-process for the formation of hydrochars with high inner surface and goodadsorption properties which can act as “activated biochar”. In recent attempts hydrochars were made from hard andsoft biomasses and hard-soft-biomass mixtures. The obtained hydrochars can be activated in a further step andused as a substitute for peat in the gardening industry, in sewage and/or waste gas purification, as a growth mediumfor microorganisms or as support for catalysts. In a recent study we successfully used hydrochars after an additionalstep of gentle pyrolysis as a catalyst carrier in fuel cells. In addition to the coal, considerable amounts of process water are generated during the HTC-process and has ahigh number of various harmful substances. Two completely different methods to lower the TOC content of HTCprocess water were tested. First, a biological way using the process water as a growth medium for micro algaechlorella vulgaris. Second, as a photocatalytic way the so-called Photo-Fenton process which employsiron-containing catalysts and H2O2 was employed.

Hydrothermal Upgrade of Bio-Oil from Thermal Catalytic Reforming


Thermo-Catalytic Reforming (TCR®) is a promising conversion technology for the production of liquid bio-fuels. TheTCR®-process combines intermediate pyrolysis and catalytic reforming of the generated intermediate pyrolysisproducts. The process is a proven technology to convert biological wastes and residues into hydrogen rich syngas,high quality oil, and char free of volatiles. The most crucial advantage, the thermal stability of the TCR®-oils, allowsdownstream processing. Hydrogen from TCR®-gas can be extracted and can be used for the upgrading ofTCR®-oil. The produced hydrogen, which is present in excess from the TCR® process, can be used for thehydrogenation and as green hydrogen for other applications because the process produces more hydrogen thanrequired for the hydrogenation. The TCR®-gas also can be used without further purification for the upgrading of theTCR®-oil. Beside the thermochemical conversion of biomass a downstream key component is the catalytichydrogenation of the TCR® oil removing the heteroatoms like nitrogen, sulfur and oxygen in order to generate highquality renewable hydrocarbons with fossil fuel like properties or green chemicals.

Novel Phosphorus Recovery from Sewage Sludge Using Supercritical Water Gasification


Because phosphorus rock is being depleted, it recovery from sewage sludge is of importance nowadays and variousmethods of phosphorus recovery have been proposed, most of which are biochemical methods. As is well known,biochemical conversion takes time, and only organics that microorganisms can digest can be treated. To circumventthis problem, we proposed application of supercritical water gasification. Supercritical water gasification candecomposes organics, leaving phosphorus in inorganic form behind in the liquid phase. Once of the characteristicsof supercritical water is low salt solubility. Thus, resulting phosphate ions can be collected as precipitate in thesupercritical water gasification reactor. In this study, we conducted gasification of sewage sludge in supercriticalwater gasification using a laboratory scale continuous reactor, and successfully recovered phosphorus separatedfrom the organics. Surprisingly, phosphorus was released to the liquid phase in inorganic form much before thecompletion of gasification. Behavior of phosphorus is discussed from the viewpoint of chemical reactionengineering.

Characteristic Comparison of Brocrude Derived from Two Types Herbaceous Biomass through Mild AlkaliHydrothermal Liquefaction


Hydrothermal liquefaction (HTL) is a promising technology for producing high density liquid fuels from herbaceousbiomass, miscanthus and kenaf. Also, high density liquid fuels through HTL can be used to conbustion fuels asheavy oil in power plant or transportation liquid fuel after purification. HTL was performed using miscanthus andkenaf as energy crops to produce biocrude and then compared with yield and chemical composition. In this study, inorder to investigate the biocrude charateristic throught mild alkali HTL, the herbaceous biomass was treated using 1% (w/w) NaOH at 350-370 °C for 30 min. Herein, to investigate biocrude yields on lignin contents variables,herbaceous biomass prior to HTL process was treated by acids and organosolv process using HCl and ethanol,respectively. As a results, biocrude characteristic was positive effected by lignin contents percentage. After HTLprocess, biocrude was analyzed by density, high calroie value, and elemental composition etc. The HTL process areeffective process to produce the high quality biocrude derived from low density herbaceous biomass.

Comparative Study of Lignin Characteristics from Different Sources and Effect on the Productivity ofLignin-Oil By Hydrothermal Liquefaction


The potential of organosolv lignins extracted from Korea native herbaceous biomass (Miscanthus and Kenaf) asfeedstock for polymeric materials and biofuel applications was assessed at hydrothermal liquefaction (HTL)process. The HTL of lignin in the presence of K2CO3 or NaOH was studied as afunction of temperature (300–450?C) at residence times of 15, 30 and 45 min. The process was carried out in a 1L fixed-bed reactor with an electricalheating jacket and In the outlet of the reactor the flow is led to a cooler to reduce the temperature and pressure untilthe ambient conditions. After HTL process, biocrude was analyzed by density, high calroie value, and elementalcomposition etc. The influence of the feedstock between miscanthus and kenaf lignins on the yield and compositionwas investigated.

Integrated Weed Management in New Harvesting Practices and Simultaneous Exploitation of AgriculturalSide Streams


Weeds are one of the most devastating constrains for agricultural plant production worldwide. Herbicide resistantweeds have become a growing problem in agriculture and international trade and traffic have contributed to thespread of seeds and plant parts and resulted in increasing problems with invasive weeds. The possibilities todevelop new effective herbicides seem to be exhausted. No new mode of actions in plants for herbicides has beendiscovered since the 1980s. The situation calls for new integrated weed management approaches to avoidincreasing weed problems in the future and new methods need to be developed to replace and supplement presentmethods. The project Sweedhart adressed this problem and the results will be presented.Dr. Glasner finished his studies of mechanical engineering with a specialization in process engineering in 2005. Hegot his PhD in the field of oil filtration with several separation/membrane technologies in 2009. Since 2009 he isresearch assistant at Fraunhofer UMSICHT in the field of biomass conversion and water treatment/management.Currently, he is responsible for international projects in the field of food processing and biomass utilization.

On Farm By-Products Composting for Resilient Agroecosystems


Increased temperatures and drier conditions, as showed by climate change scenarios, could lead to loss of plantcover and rapid lowering of organic matter input in European cultivated soils. The organic carbon decline in soilsthreatens soil fertility and the capacity to retain water, thus worsening the adverse climate change effects. Theprincipal aims of the pilot-scale demonstration project were to identify, implement and test low-cost managementstrategies for soil protection based on soil organic improver production and application, combined to cover cropsintroduction.In a study realized over twenty years on orange trees (Citrus sinensis (L.) Osbeck) the effects of citrus by-productcompost (CC) on soil fertility, plant nutrition and performance was verified.Our results allow reconsidering the role of on-farm composting of agricultural by-products in the framework of theintegrated cycle of biomasses.

Economic and Biomass Assessment of Crop Residues in Static Solid State Digester


Ambitious objectives are based on biomass from agriculture for French energy transition strategy. Anaerobicdigestion is one of the process showcased by policy drivers (EMAA, 2013), especially breeding systems for manurevalorisation. Farmers from cropping systems could be interested in crop residues valorisation into on-farm biogasplants. But solid state digestion process has to be adapted for better yields. Crop residues were collected andanalysed during RESIMETHA program. Digestion was tested from lab to large scale leached bed reactor includingpilot plant. Technical, economic and environmental assessment was realised. The impact on biomass resourceswas simulated including digestate use.

Impacts of Chp and Combined H2, Heat and Power Production for Green Local Transportation: A SicilianAgro-Food Industry Case


This work deals with the assessment of the potential impacts of residual biomass gasification integrated with theSicilian agro-food industries. Indeed, these residues are still unexploited by the bioenergy sector, and furthertechnology developments are needed. The residue that has been considered is citrus peel, a byproduct of citrusjuice production. Hence, this work aims to evidence the potential of polygeneration from an air-steamgasification-CHP system in the context of a citrus juice factory. Two case study have been analyzed: the first dealswith combined heat and power to be integrated with the factory, while the second one deal with hydrogen, heat andpower production for developing local green transportation. Both cases studies are carried out with the aid of anexperimentally validated air-steam gasification simulation model, while the constructor provides the CHP data. Thepotential impacts on local transportation are assessed including the on-road data of hybrid mini-buses carried out byCNR-ITAE researchers.

On-Site Production of Xylanases by Moesziomyces Aphidis Using Barley Straw as Feedstock TowardsLignocellulosic Ethanol


Enzymes cost still constitutes one of the major barriers for the commercial implementation of lignocellulosic ethanol.Therefore, search for more efficient enzymes and cost-effective production processes is required. While efficientcommercial cellulases are available, the different hemicelluloses found in nature require the development offeedstock-specifichemicellulases. The present work targeted the inexpensive production of novel xylanases to be applied on-site forconversion of lignocellulosic biomass into ethanol.

A Fermentable Glucose-Rich Stream Through the Optimal Enzymatic Hydrolysis of the Starch and CelluloseFraction of the Typha Domingensis Plant Biomass


The macrophyte plant Typha domingensis is explored within a framework of integrated plant exploitation. Precisely,we take advantage of both its potential to be used for wastewater treatment, as well as the dual polysaccharidereserve tanks exhibited by the plant, due to its starch and cellulose composition. Typha domingensis (cattail) rootsand rhizomes demonstrate a high starch content, which is a polysaccharides surplus comparing to herbaceousplants. The available carbohydrates are acquired from two resources: the nonstructural, digestible glucans fromstarch and the more rigid glucan matrix of structural cellulose.The proposed valorization of the entire plant biomass, through the combined starch and cellulose enzymatichydrolysis, results in a glucose stream of sufficiently high concentration and improved biomass bioconversion index,which generates promising routes for sustainable glucose fermentation to bioethanol and/or other bioproducts.

Imaging Techniques for Understanding Physico-Mechanical Modifications of Lignocellulosic Biomass Dueto Hydrothermal Pretreatment


In the production of second-generation bioethanol, lignocellulosic biomass needs a pretreatment to overcome itsrecalcitrant macromolecular structure and to improve carbohydrates’ accessibility for enzymatic hydrolysis. In thiswork, two imaging techniques were used to assess changes in ultrastructural characteristics of poplar’s cell wallcaused by hydrothermal (HT) pretreatment. Firstly, chemical changes in the different layers of the cell wall beforeand after pretreatment were observed by two-dimensional chemical mapping through Raman micro-spectrometry.Secondly, anatomical changes on the cell wall structure were observed by X-ray nano-tomography. The comparisonbetween pretreated and raw biomass revealed shrinkage and thinning of cell wall as well as sub-parietal chemicalchanges. These results can be related to the mechanical behavior of the lignocellulosic biomass observed atmacro-scale.

Energy Optimization of Fermenter Mixing - Effect of Vessel-Agitator Arrangement


The fermenter mixing in technologies of production of biofuels has crucial influence on the fermentation processitself. Mixed batch has strongly heterogeneous character in these technologies. The mixing must ensurehomogenization and circulation of the whole batch in the fermenter – this ensures the fermentation process itselfwhich is connected with transfer of the heat and mass. The ensuring of homogenization and circulation of the mixedbatch and its tempering represent main energy demands of the fermentation equipment in biofuels productiontechnologies. These energy demands can be greatly reduced using the advantageous arrangement of theconstruction of the fermenter and thus greatly lower energy demands of the whole process and technology. This canbe especially reach for given fermentation process using the advantageous arrangement of the vessel andhydrodynamically optimized (hydrofoil) impeller in dependance on the properties of the mixed batch.

Development of an Integrated Bioenergy Hybrid Furnace for Industrial-Scale Grid Balancing


The production of cement emitted approximately 3.0 Gt of carbon dioxide (CO 2 ) in 2014, which corresponds toabout7 % of the global total. Roughly 60 % of CO2 emissions from cement making come from the calcination reaction andthe rest from burning fossil fuel to provide the needed high-temperature heat. We present and concept andexperimental results from an innovative hybrid furnace that can be powered by by biomass, biogas, zero-carbonelectricity, or hydrogen produced with zero-carbon electricity, and can be optimised based on the cost of energy andCO2 emissions. We also show how the furnace’s concentrated CO2 exhaust can be used to produce electrofuels (power-to-gas orpower-to-fuels) and what kind of opportunities the low-carbon hybrid furnace offers for balancing the electricity grid.

Integration of Biogas Power Plants into Weak Distribution Grids


Due to the expansion of volatile power generation from wind and solar energy, the demand for advanced energysystem manage-ment is steadily increasing. To meet the resulting challenges and ensure future electricity gridstability, controllable generation units are required. In this context, the Institute of new Energy Systems atTechnische Hochschule Ingolstadt is working on the research project “NETFLEX – Development of a predictivecontrol system for the integration of biogas plants into electricity grids with a high proportion of volatile powergenerators”, funded by the German Federal Ministry of Food and Agriculture. The aim of the project is to developmodel based innovative operation strategies and a predictive control system for biogas plants to avoid short-termelectricity grid overload and to contribute to grid stability in local electricity distribution grids. State-of-the-art systemcomponents as well as control concepts will be selected and simulated to be able to extend the existing commercialbiogas plant in Zellerfeld, Germany, by a modern cloud tracking system and a novel predictive control system toachieve the above stated goal.

How to Measure Flexibility – Performance Indicators for Demand Driven Biogas Plants


The general focus is on flexible power provision from biogas, which can significantly contribute to energy systemswith high shares of volatile renewables in the power sector. However, an open issue was still, how this flexibility canbe measured and which indicators for demand driven biogas plants can be applied. Further characteristics anddemands for this flexibility were not clearly defined or measured. We define eight indicators to describe and analyze“flexibility”. The indicators were tested for eight research projects focusing on flexible energy provision based onbiogas plants. One result is that the applied indicators allow a comparison of different approaches for flexible biogas plants withregard to velocity (ramps), power range (bandwidth) and duration for specific load conditions. Based on theseindicators bottlenecks for the determination of the flexibility potential were identified. Hence, the results can be used to modify influencing factors to gain different aspects/modes of flexibility and toidentify targets for further research. The detected interaction among factors and indicators highlights possibletrade-offs.

In order to enlarge the market penetration of FPBO researchis carried out to enable other applications, like residential heating, for using FPBO. For FPBO market introduction itis important that standards and norms are in place which is nowadays the case for FPBO usage in industrial boilerswhere both ASTM and EN standards exist. Another topic of attention for widespread market introduction is REACHregistration for the potential impact on both human health and the environment. Currently, REACH registration hasbeen done for the use of FPBO in industrial boilers. However, still some reliable methods for accuratecharacterization of i.e. low levels of sulphur, and chlorine, and specific polar and non-polar compounds as indicatedin the REACH registration need to be taken into account. This paper discusses the standardisation and registrationof residential boiler grade FPBO.

Compression Ratios Comparisons between Engines Operating with Producer Gas


Compression ratio is one of the main properties of a reciprocating internal combustion engine defined by itsgeometry. Typical values are between 8 and 12 for Spark Ignition (SI) engines and between 12 to 24 forCompression Ignition (CI) engines. The ignition in engine operating with producer gas take place via spark thanks toa higher octane rating compared to gasoline, it is possible to use engine with a higher compression ratio in order toincrease the thermal efficiency of the process. To test the behaviors of the producer gas combustion with differentcompression ratios four engines were used. The comparison was based on the exhaust emission and on themaximum electrical power output reached for each engine.

Removal of Process Disturbing Inorganic Substances from Softwood Bark


The need for utilizing waste biomass resources and energy effectivizations at modern pulp mills has highlighted barkas an interesting resource to produce densified biofuels. Thermal upgrading of bark through the steam explosionprocess has been proven a successful pretreatment to produce durable pellets. However, the steam explosionprocess does not remove any inorganic impurities, and this study focused on separation technologies in combinationwith steam explosion to remove these contaminations. Prior to steam explosion the following treatments were tested:-Star screening, with and without following windshifting-Leaching-Simplified separation (reference)After steam explosion a pilot scale cyclone was tested for the removal of dense particles. The results highlight the importance to optimize the impurity removal versus biomass loss.

Torrefaction as a Pre-Processing Technology for Improving the Final Quality of Biomass Derived SolidFuels: the Effective Reduction of Chlorine Contents in Waste Biomass


The use of biomass for the production of energy has been gaining a growing area of demand and acceptance, givenits attributions, particularly with regard to possibilities as a substitute for coal, either wholly or in a co-firing system.However, when analyzing the results of this use, a number of less advantageous situations arise, mainly related tosome properties of the biomass, such as its low density, low calorific value or difficulty in handling operations. In thisway, torrefaction, as well as other thermochemical conversion technologies, can play a decisive role, since they canserve as potentiators of the use of biomass in the substitution of other fuels, especially those of fossil origin.Evidence of the results described here allows a new perspective to be set for this technology, but also for thedifferent types of biomass that can begin to be used for the production of higher quality solid fuels. This qualityessentially refers to the presence of some chemical elements, such as chlorine or alkaly metals, which cancontribute significantly to the occurrence of corrosion phenomena during the combustion process, causing seriousdamage and unexpected stops.

Optimization of Economizers for Biomass Combined Heat and Power Units


The overall efficiency of a biomass fueled Combined Heat and Power (CHP) unit is large depending of the flue gastemperature of the flue gas stack. The deeper the flue gas can be cooled the higher the overall efficiency of theinstallation becomes. However flue gas contains acids that condense when cooling to below the acid dew point.In practice, cooling of the flue gas is limited to 130 – 170°C in order to reduce condensation of acids on the coolersurface, resulting in accelerated corrosion. The corrosion mechanisms in such an ECOnomizer are complexbecause of the interaction with other components. For this reason, suppliers of economizers often chose tooconservative values based on rule of thumb for coal fired installations. The primary goal of the project is to increase the overall efficiency of biomass fired boilers by reducing the heat lossof the flue gas by the stack and to produce heat at a higher temperature than the typical flue gas condenser. Formany applications, heat of 70°C can be used and the foreseen ECOnomizer of this project is aimed at thistemperature level, whilst being developed to be corrosion resistant under acid condensing conditions.

Ash Deposit Behavior According to Various Additive with Different Chemical Composition in Co-Firing ofBiomass


As the usage of coal has continuously generated carbon dioxide, the whole world has been faced climate problemsuch as global warming. Biomass is currently a best alternative for a part of coal as fuel, so that use of biomass isconstantly increasing for power generation around the world. For promoting usage of domestic biomass in Korea thegovernment is especially preparing to change energy policy that domestic biomass has more weight than importedbiomass in terms of Renewable Energy Certificate (REC). Most herbaceous biomass are consisted of Koreanbiomass. So, it would be expected to apply herbaceous biomass to power plant for gaining more REC. Theherbaceous however, is difference with woody biomass in terms of ash (ash content and element component). Andthe herbaceous biomass produced a lot of Ash in the biomass. The problem with ash is that slagging and fouling areformed in the boiler system, which reduces the efficiency of the boiler and disrupts the system, resulting ineconomical and efficient problems. Therefore, the purpose of this study is to investigate the effect of additive forreducing the slag of problems caused by herbaceous biomass co-firing.

Performance Evaluation of an Electrostatic Precipitator in a Small-Scale Biomass Boiler by Using DifferentBiomass Feedstocks


In order to evaluate the performance of an electrostatic precipitator (ESP), comprehensive test runs investigatingboth particulate matter (PM) and gaseous emissions were performed by using softwood pellets as well as newbiomass feedstocks such as short rotation coppice (poplar) and biomass residues (maize). An ESP was directlyintegrated in a commercially available small-scale biomass boiler. Based on wet chemical analyses of the fuels,so-called fuel indexes were calculated to deliver primary information on the combustion behaviour to be expected.The overall aim was to determine appropriate operating conditions, to optimise combustion parameters in order tominimise PM and gaseous emissions as well as to inhibit ash related problems. This was done by an efficientcombination of primary (air staging in combination with an innovative control system) and secondary measures(integration of an ESP) and showed an enormous potential for both, a stable plant operation and reduced PMemissions. Thus the findings provide the basis for developing a fuel flexible, low emission and highly efficientbiomass boiler in the sector of small-scale combustion systems.

Alkaline Laccases for Lignin Valorisation


MetGen is a Finnish biotechnology company developing and supplying industrial enzymes and enzymatic processesfor lignocellulosic biomass valorisation. In particular, lignin valorisation is one of the main challenges for theeconomic feasibility of Biorefineries due to its heterogeneous chemical composition, recalcitrance, and poorsolubility. One of the latest achievements of MetGen was the production of lignin oxidizing enzymes - MetZyme®PURECO™ - extremely alkaline and thermostable laccases capable of addressing lignin at its soluble state. In thiswork, the kinetics of MetZyme® PURECO™ and its effect on the proprieties of several technical lignins in differentoperation conditions were examined in terms of molecular size distribution as well as in the change in chemical,morphological and structural features. Results show that MetZyme® PURECO™ is stable in lignin solutions underhighly alkaline conditions and clearly enhance lignin proprieties. Moreover, this enzyme-based technology wasdeveloped as an integrated, sustainable and organic solvent-free process that can be applied at the industrial scaleand boost the Biorefinery sector.

Hydrothermal Catalysis to Valorize Biofeedstocks into High Value Special Chemicals


Hydrothermal catalysis is an important thermochemical conversion process that is used to valorize biofeedstocksinto valuable platform chemicals over various heterogeneous/homogeneous catalysts. One-pot hydrothermalcatalytic conversion of sugar-rich microalgae as fresh biofeedstocks to important and valuable platform chemicals,such as glycols (1,2-propanediol and ethylene glycol) 5-hydroxymethylfurfural (5-HMF) and lactic acid (LA) withyields of 53.6%, 48.0% and 83.0% respectively were developed under mild reaction conditions over heterogeneouscatalysts. Reaction networks and mechanism were systematically investigated through experiments and DFTcalculations to gain insights into the activation of the C-O and C-C bonds.

Techno-Economic Assessment of Bio-Coal Production Through Wet and Dry Torrefaction Processes ofDifferent Biomass Feedstocks


In this study, the economics of bio-coal production from different types of feedstocks (pine, wheat straw, grapepomace, manure and algae) through wet and dry torrefaction are assessed. The results of detailed techno-economicanalysis of the two processes are compared and discussed. Through simulation of the processes and developingtechno-economic models, cost of production of bio-coal associated with each process is evaluated. The resultsindicated that biocoal from wet torrefaction (Hydrochar) have superior characteristics and more coal-like propertiesthan biocoal (biochar) from dry torrefaction. However, hydrochars have lower yields and higher production costs thanbiochars (except for the pathways with manure as feedstock; in these, the hydrochar production cost is lower). Thelowest and highest mass yields of wet and dry torrefaction processes are from algae biomass at 36.88% and 50%and wheat straw at 80.5% and 83%, respectively. The lowest production costs (without carbon credit) can beachieved through dry and wet torrefaction of grape pomace at 2.29 $/GJ and 4.14 $/GJ, respectively.

Performance of a compost and biochar packed biofilter for H2S removal


The last years have shown an explosion of interest about biochars. While the main application targeted continues tobe soil improving material, more and more studies explore other options, such as the use of biochars for gasadsorption. In particular, it could be of interest to mix biochar and compost in biofilters for removal of H2S containedin biogas produced during anaerobic digestion. To our knowledge, this application has not been evaluated yet.The main aim of this study is therefore to evaluate the performance of an aerobic pilot biofilter packed with a mix ofbiochar and compost for the removal of H2S.

Customizing Biomass as Reducing Agent in Blast Furnace Ironmaking- Preliminary Result


Steel production via blast furnace (BF) utilizes coke and coal to reduce iron oxides which results in high greenhousegas (GHG) emissions. One possibility to mitigate fossil GHG emissions in steel production is to replace fossilreducing agents by biomass-based reducing agents (bioreducers). Charcoal as bioreducer was used in thebeginning of steelmaking. Today, most commonly reported biomass utilization in the blast furnace is in the form ofcharcoal via tuyeres to replace pulverized coal injection (PCI). The injection of charcoal fines is used in smallcharcoal BFs in Brazil. However, large furnaces have different quality and process requirements (including stronglump coke as well as large supply of biomass). Hence, further work is needed in order to customize the bioreducers.

Biochar from Biogenic Residues and Waste: A Techno-Economic Assessment of CarbonizationTechnologies


Carbonization offers the possibility of converting biogenic residues and waste materials into biochar and thus makingthem more energy efficient or materially usable. Currently, various carbonization technologies are underdevelopment, which differ significantly in their chosen process conditions. Here are to be called the hydrothermalcarbonization (HTC), the biomass steam conditioning (BSP, Biomass Steam Processing), the slow pyrolysis as wellas their process relatives, the torrefaction. Due to the still relatively early stage of development, only a few estimatesare available on the cost-effectiveness of these technologies. Therefore, the aim of this investigation was to analyzeand evaluate the selected carbonization technologies listed above for biogenic residues and waste fromtechnological and economic aspects. submitted for Visual Poster Presentation

Coupling Electricity and Biomass to Biofuels Systems to Increase Performances in Mobility - An Overview


In Europe, the final energy dedicated to mobility stands for about 30-40% and is almost 100% based oncarbonaceous fossil resources. Reducing the part of fossils in mobility and CO2 emissions is then a major concern.In the past decades, biofuels or hydrogen use as energy carriers were envisaged as a solution. More recently, thebattery implementation in the mobility system seems to be considered as “the solution”. The present study try toanswer to two main questions:•Is there possible to find a good trade-off between the use of electricity and second generation biofuels in thetransport sector and especially in road mobility? Particularly, the PHEV contribution a good solution? In thiscomparison, carbon considered as renewable come from biomass to produce biofuels (BtL) or from CO2 to producefuesl from power (PtL).•Is there possible to increase the biofuel production performances combining biomass and electric power, thru theuse of hydrogen? Particularly, as hydrogen should be produced from electricity, what is the impact of the electricityproduction in terms of CO2 emissions?

A Meta-Analysis on Terrestrial Bio-Pumps - Sequestering Carbon in Soils While Producing SustainableBiomass Streams for the Bioeconomy


This study investigates, through a meta-analysis, the possibility to integrate in the European landscape terrestrialbiomass species acting as bio-pumps, i.e. allowing for a net transfer of carbon towards the soil carbon pool (e.g.alfalfa, tall festuca-, deep-root species). Through a stringent protocol involving several selection criteria, wesearched the literature on studies reporting the yield and soil carbon changes of any bio-pump species that havebeen reported to grow under Western European conditions. Three search engines were used, and peer-reviewedarticles as well as gray literature were included. The key research questions to be answered by this work in progressare as follows: (i) What are the biomass species that could allow inducing a net carbon sink in European soils, whatsequestration ranges could be expected towards 2050 and what would these mainly depend upon?; (ii) Whatbiomass yield could be obtained and what biomass composition could be expected at harvest?; and finally (iii) Arethere any environmental risks that can be foreseen from the broad deployment of the bio-pumps identified in (i), whatare their extent and how could these be limited?

Cultivation of Energy Crops in Marginal Soils - Technological, Environmental, Social and EconomicOpportunities and Risks


An increasing awareness that the supply and security of petroleum-based materials is diminishing, coupled withenvironmental concerns, has increased demand for more sustainable systems, of which biomass resources are oneof the pillars. Energy crops are promising because of their high productivities and biomass characteristics which canreplace products of fossil origin. Yet, the demand for biomass increases the risk of conflicts on land use. Hence,segregating the growth of dedicated biomass crops on marginal land, is considered an option to avoid theseconflicts, as most of the energy crops are considered tolerant to soil marginality. Yet, yields and biomass quality canbe affected by the soil marginality, reducing the environmental savings and compromising its economic exploitation.Nonetheless the production of energy crops on marginal soils may contribute to improve the quality of soil and thebiological and landscape diversity. In this context, studies on the production of energy crops in marginal soils arereviewed, taking into account environmental, economic and socio-economic aspects as also the technologicalobstacles associated with biomass characteristics.

Air Gasification of Solid Recovered Fuel (Srf) in Lab-Scale Fluidized-Bed


Solid recovered fuel (SRF) can be produced from the non-recyclable MSW, and can be valorised as fuel. SRFcontain typically lignocellulosic biomass and plastics. The gasification process appears as a promising way toconvert SRF into “syngas”, that can be valorised in Combined Heat & Power applications, and as precursor in theproduction of gaseous or liquid fuel. The gasification of Solid Recovered Fuel (SRF) was studied in an air-blown bubbling fluidized bed. The contributionof gasification temperature and equivalence ratio (ER) on the gasification efficiency was separately investigated bysequentially varying these two parameters. As inorganic gases are known to represent a significant issue for thevalorization of syngas from waste, the syngas contents in H2S, HCl, HCN and NH3 were measured. In addition, thefate of S, Cl and N during the gasification was investigated by performing mass balances to determine theirdistribution in the different products (inorganic gases, fly ash, bed material).

Landfill Solid Waste-Based Syngas Purification by a Hybrid Pulsed Corona Plasma Unit.


Obtaining syngas from landfilled waste has been proposed as a sound solution for the environmental, energy andland availability challenges that human being is currently facing. However, the syngas obtained from waste, as wellas from other renewable sources, is heavily polluted with tar. In this work, a solution to remove tar is proposed: tointroduce an electrical discharge ( pulsed corona plasma ) into a thermal cracking unit. The results of ourexperiments demonstrate that the pulsed corona plasma is able to reduce the tar cracking temperature, which canmake the landfilled waste gasification process easier to implement.

Catalytic Tar Reforming with Sewage Sludge Char of a Producer Gas from Fluidized Bed Co-Gasification ofSewage Sludge and Wood


Fluidized bed gasification of sewage sludge is a promising method for its valorisation due to the fuel flexibility of theprocess. The main drawbacks are the impurities present in the producer gas, with a high tar content, and its lowcalorific value. In this study, sewage sludge and wood mixtures are gasified in a fluidized bed. A tar cracking reactoris used to reduce the amount of tars and to increase the calorific value of the producer gas. Sewage sludge char isemployed for tar cracking with a real producer gas, showing the feasibility of the process, which could employ aby-product of the gasifier. Char deactivation is also investigated in a test conducted during several hours, as well asthe possibility of reactivating the char with steam, showing promising results.

Char Recirculation for Improving the Conversion Yields in Fixed Bed Gasification Systems


Most of the recent developments in the small-scale gasification technology available in the market aim at reducingas much as possible the amount of material to be disposed, integrating into the plant an additional oxidizing section,i.e. afterburner, in order to have an outlet material stream mainly composed by ashes.The aim of the present work is to investigate an alternative solution for reducing the amount of generated char and atthe same time increasing the efficiency of the whole conversion process. The proposed solution, investigated in asmall-scale open-top gasifier installed at the Free University of Bolzano, is to recirculate the char inside the gasifierin order to increase the residence time and the conversion yields. The gasifier has been upgraded with theinstallation of a hopper, a fine separator and a conveyor belt for the automation of the char recirculation.To supplement the analysis, a thermodynamic equilibrium model has been developed for the identification of themaximum theoretical performance of the system based on thermodynamic constraints and is being validated againstthe experimental results.

Screening of Oleaginous Yeasts for Lipid Production Using Volatile Fatty Acids as Novel Substrate


Microbial oil biosynthesis using wastes as substrate is a promising technology to reduce biodiesel production costs.Most studies focus on sugar substrates; however, this work shows the ability of some yeast to use alternativesubstrates. Volatile fatty acids (VFAs) can be used as low cost material because they can be generated from avariety of organic wastes via anaerobic digestion (AD). Besides, oleaginous yeasts (OY) metabolize free fatty acidsand transform them into lipid. In this study, six OY were screened growing on digestate at three VFAsconcentrations: 5, 10 and 15 g/L. Yeasts growth and lipid accumulation were evaluated. Regardless of VFAsconcentrations, four of the six strains were able to grow on the digestate reaching 5 g biomass/L. The highest lipidaccumulations were determined in C. curvatus and W. hansenula (36.9 and 33.9 %, w/w respectively). The mainfatty acids obtained in all strains were oleic, palmitic and linoleic acids accounting for 70% of the lipids, making yeastoil suitable for biodiesel production. Results were extremely positive since C. curvatus, W. hansenula and Y.lipolytica arise as candidates for lipid production using digestate.

Demonstration of the Use of Silage of Mixed Sugar Beet Leaves and Straw for Biogas Production


The project; Demonstration of the use of silage of mixed sugar beet leaves and straw for biogas production is basedon a recent project that established the fact that a silage mix of sugar beet leaves and straw is an excellent substratefor biogas production. As both materials are agricultural residues the silage can be produced without charging extraagricultural land alternatively used for food production. Moreover it proved a significant boost of the methane yieldsfrom the straw component as a kind of synergy effect. The project will demonstrate the practical production and useof the silage on two farm scale biogas plants. The most rational work processes will be clarified and it will beanalysed if the mentioned synergy effect can be found in a full scale operation

Two Previous Markets of Bioenergy, and New Approach as Third Way in Japan


In Japan, 2 previous markets of bioenergy have been embed since 2000. The former is huge Electricity power plant(5M-50MW) and the latter is heat market for or warm bath facility, house for agriculture, home for the aged person,etc. However, both electric power and heat have some issues. So I suppose new approach as third way, that installs bioenergy to household sector like Europe, especially new orrenovated apartment in rural area. Municipality should build the apartment for new residence, who are aged or youngimmigrant from city area, and also installing bioenergy for heating. There are 4 cases of apartment installedbioenergy. We compared with the price, depending facility, starting year of 4 cases. Especially, the price has thewide range. It shows the market of bioenergy haven’t matured yet. Therefore, we should grow this market throughvarious projects in future.

Model and Laboratory Based Analysis of a Flexible Feeding of Biogas Plants


The development of systems for energy storage and demand-driven energy production will be essential to enablethe switch from fossil to renewable energy sources in future. To cover the residual load rises, a rigorous dynamicprocess model based on the Anaerobic Digestion Model No. 1 (ADM1) was applied to analyze the flexible operationof biogas plants. For this, the model was optimized and extended with an intelligent feeding algorithm. Essentialfeeding times and quantities of available substrates were calculated so that a biogas plant can cover a definedenergy demand. Finally, an operation concept for a demand-driven energy production was worked out using differentsubstrates. The results prove that a flexible operation of biogas plants with an intelligent feeding program is possible.

Competitive Biomass Key Applications to Fulfill Climate Targets in the German Heat Sector: Findings fromOptimization Modelling


Fulfilling the ambitious greenhouse gas (GHG) reduction targets in Germany requires the use of renewabletechnologies in the heat sector. Biomass is the renewable key player in the German heat sector today, but powerbased solutions are expected to grow where this is possible. However, for some applications, especially in theindustry, renewable non-biogenic alternatives are rare or not existent. Our investigation aims on finding theapplications in the heat sector, in which biomass is used as a competitive key technology to fulfill the defined GHGreduction targets. To address this topic, we set up an economic optimization model, investigating the cost optimalallocation of biomass under long-term climate protection scenarios until 2050. If the use of biomass in the heatsector is necessary to fulfill these targets, we will identify the required biomass key applications within our scenariomodelling.

Analysis on the Coupling of Biomass Gasification Processes with a Parabolic trough Concentrating SolarPlant


Gasification is a convenient way to convert a solid fuel, the biomass, into a gaseous fuel, through a thermaldegradation process. The required energy is usually supplied by the partial oxidation of the fuel in the gasificationreactor. The use of solar power as an external thermal input is attractive to improve the energy content and thequality of the product gas. This research investigates the benefits ensured by this coupling to both plant technologiesand explains the method in case of agro-industrial residuals used as feed. Aim of this work is to find the reactions tobe supplied at a temperature compatible to the molten salts in the solar troughs, the way to carry out this process,propose a proper reactor design and finally size the solar plant to be best coupled with the gasifier.

Storing Renewable Energy by Biogas Upgrading


The MeGa-StoRE project investigates catalytically upgrading biogas to natural gas by methanisation of the carbondioxide from the biogas. This technology is proposed as an energy storage solution, as the hydrogen required for theconversion can be supplied by renewable energy driven electrolysis. This energy storage solution interconnectsthree main energy infrastructures: The biomass supplies the carbon dioxide, the power grid supplies electricity forhydrogen production and the final product, methane, is stored in the natural gas grid. Thus, storing renewable energyby biogas methanisation will not require major changes in the energy infrastructures of today.

Methane Reforming and Water Electrolysis System Integrated in a DME Synthesis Plant from BiomassBased on Sorption-Enhanced Technologies


Addressing the need of alternative fuels for the decarbonization of the transport sector, this work focuses on DMEproduction as Diesel substitute, synthetized from biomass or waste. In particular, FLEDGED project investigates anew route for DME synthesis from biomass, aiming at process intensification and cost reduction. The processinvolves a Sorption-Enhanced Gasifier (SEG) and a Sorption-Enhanced DME synthesis (SEDMES). These twotechnologies improve fuel flexibility and allow for Power-to-X (P2X) integration. In this work, the whole plant issimulated using Aspen Plus, focusing on the coupled integration of hydrogen from water electrolysis andauto-thermal reforming for improving the fuel yield. This solution has been benchmarked against the reference plantwithout reforming and the auto-thermal option with oxygen produced by an ASU. The reforming step increases thecold gas efficiency recovering the methane in the syngas. The hydrogen admixing provide an average additionalDME production of 0.50 MJ DME/MJel, contributing to the integration of electrical renewable energy sources in thetransport sector and to the electric grid balancing.

Assessments of a Complete C-Recovery Biogas Plant Via Upgrading and CO2 Methanation


In order to match the two opportunities offered by biogas plants (electricity and biomethane production) and to pushforward the virtuous trend of production and injection of renewable gases, the aim of the presented work is theanalysis of an innovative biogas upgrading plant retrofitted with CO2 methanation to produce additional methane tobe injected into the grid. The idea of the proposed layout is to perform a complete C-atom recovery from the biogasstream by matching the traditional biogas upgrading path with a more innovative CO2 methanation reactor fed byhydrogen locally produced through a low temperature electrolyzer. The plant also includes the possibility of havingpart of the biogas sent to a small-medium size internal combustion engine, able to cover plant internal loads(electrical and thermal). The plant design includes an efficient thermal integration between components, alsoexploiting the heat available from the methanation reactor for covering the plant thermal loads. Integration with otherlocally available renewable sources (photovoltaics) is also considered, in order to ensure a fully-renewable methaneproduction.

Ash Management at Biomass Heating Plants in Southern Germany


Note: The content my also be appropriate to conference topic 2.3 Combustion of solid biofuels in biomass heat (and power) plants produces ashes. On the one hand, these asheshave properties that suggest utilization, e. g. as fertilizers or building materials. On the other hand, the ashes may becontaminated with environmental pollutants. Shortage of landfill space, the changed legal situation as well asbio-economical demands to close natural cycles makes the material use of wood ashes increasingly attractive. Littleis known about how German biomass heating plants actually dispose or recycle their ashes, which costs areincurred and the ob-stacles to a material use of the ashes from an operator’s point of view. Thus, the aim of thisstudy is to record the current “status quo" of handling biomass ashes in German biomass heat (and power) plants.This knowledge will be used to develop strategies on plant level and on a general level for an increased material useof biomass ashes.

Tomato Genetic Variants for Peel Color, a Source of Biocompounds and Biomass for Energy Recovery


In Italy, the tomato processing industry produces hundreds of tons of residues, which poses serious problems ofdisposal and represents a loss in terms of biomass and nutrients. At least 2-3% of these wastes are constituted bytomato peel. The exploitation of waste will benefit of the process innovation, but at the same time must consider thechallenges raised by the advent of new biological resources. Tomato breeding is providing lines characterized by avariety of fruit pigmentation, from yellow to black, and the mutations determining such phenotypes have beenintroduced into commercial varieties. Some tomato variants altered in fruit pigmentation were studied. The peelextracted from the fruit was characterized for content of bioactive compounds (chlorophyll, polyphenols andcarotenoids) and energy parameters (moisture, ashes and heating value; potential biogas yield through Buswellformula). The work aimed at proposing a potential supply chain where a by-product of tomato industry (tomato peel)could be fully re-used for the recovery of bioactive substances and the production of biogas.

The novelty of the research is in the methodology itself, which involved thedevelopment of TEEA as sequential and screening evaluation tool through the following assessment phases: 1)technical feasibility, 2) economic profitability and 3) environmental sustainability. The TEEA was performed for threewaste biomass categories (sugar, starch and lignocellulosic) considered as feedstock for a biological conversionprocess under the same boundary conditions.

Optimization of the activated carbons synthesis of peanut shells, applying surface methodology


In this study the optimization of the conditions of preparation of activated carbons by chemical activation of peanutshell is presented. One will use a mathematical model, based on the surface response methodology. Theexperimental responses considered are the AC yield and the iodine number. The influences of its various factors onthe responses have been modelled by a quadratic model of the second order in satisfactory ways. The study of theparameters and the use of experimental designs made it possible to determine the optimum calcination temperatureconditions, the concentration of the activating agent and the residence time in the furnace. Physico-chemicalanalysis techniques such as the FTIR allow obtaining different functional groups present on the surface of thesubstrates. SEM informed about the porous structure of the absorbents. In the end, this method makes it possible tobetter control the parameters influenced by the preparation of the optimized activated carbon.

Biogas Production for Transport Fuel - Improving Manure Handling in Luga District, Russia


According to Baltic Sea Action Plan, nutrient inputs to the Baltic Sea from HELCOM countries should be reduced by11% (N) and 44% (P). Still, emission reductions remain too modest and feasible indicators and reliable data onemissions are lacking. Especially actions to reduce emissions from rural areas and agriculture have not beeneffective.In Russia, biomass is not widely used for energy recovery, although Russia has the largest biomass resources in theworld. Manure from the cattle farms in Luga district could provide valuable energy resource and at the same time,manure handling would reduce the harmful impact of cattle farming to the environment. One solution could be use ofmanure as a substrate for biogas production.

Scenario-based Analysis for the Integration of Renewable Gases into the German Gas Market


The German heating market is strongly dependent on natural gas (NG). In 2016, NG covered about 50% of theGerman heat demand. Only approximately 13% was provided by renewable energies. In order to achieve thenational environmental targets, the share of renewable energies in the heating sector needs to be increasedsubstantially. The Chair of Energy Process Engineering at Friedrich-Alexander University Erlangen-Nürnbergdeveloped and implemented the simulation based optimisation model MIREG (Model for the Integration ofRenewable Gases) in order to investigate scenarios for the integration of green gases into the German gas market.This contribution will describe the modelling approach and present simulation results of possible marketdevelopments under different governmental funding strategies.

Comparing Strategies of Biogas Energy Use: Electricity Generation Versus Biomethane Production


This paper discusses two options for biogas utilization: electricity generation and biomethane production. It arguesthey provide different services for the energy sector, and based on the successful international experiences ofGermany and Sweden, that one of the options may be preferred depending on the context. It uses theseassumptions to evaluate Brazil’s case, aiming at finding the optimal solution for biogas utilization in the country. Theconclusions are that biomethane can have a very positive impact, but has many barriers to overcome, while in thepower sector it is a more established alternative with the ability to provide important features, such as low-carbonbaseload and flexibility.

Investigation of the Influence of Fuel Characteristics on Biomass Combustion in Real and LaboratoryConditions


Results of investigation of the influence of bale quality to the process of biomass combustion shows that carefulbales choosing avoid many problems in the boiler operation, would reduce the number of delays, to facilitate theboiler operators and would provide a safer production for useers. Performed experimental investigation hasdemonstrated that the use of additives allows for safe and reliable biomass combustion, even of biomass varietiescharacterized by low ash melting temperature, such as wheat straw and maize. Investigation of the characteristics ofagricultural biomass exposed to the process of leaching and washing indicate that the washing of wheat strawaffects the chemical composition of the ash, which is reflected in the increase, i.e. raising the ash solubilitytemperatures. The results of the performed tests in laboratory experimental furnace with thermal power of 50 kW inmany ways help to better behavior the process of baled biomass combustion in order to avoid the exploitationproblems of the use of agricultural biomass. Also, the results of this research will be used in designing andconstructhe new plants that will burn agricultural baled biomass.

Quality Assessment of Wood Pellets for Residential Heating Systems and Combustion Behavior an a PelletStove


Wood pellets are widely used in pellet stoves and pellet boilers all over Europe. A high proportion of the pellets soldon the market are already labelled with ENplus but a pellet screening which was conducted in Slovenia has provenlow quality pellets. Another interesting issue is the chemical composition of pellets since this also influences theemission behaviour of pellets during combustion. One of the main contributors to particulate matter emissions is theaerosol forming element potassium (K) which is not limited in any pellet standard or quality label. Therefore, a highquality pellet stove may not meet the national regulations on particulate matter emission if potassium content is toohigh. This was one of the reasons for performing the pellet screening considering 42 different pellet samplescollected on the European market. Twelve of these pellet samples were finally selected for combustion tests in aconventional pellet stove showing different Emission behaviour while using the same stove settings.

Contamination of Wood Pellets with Selected Mineral Soils - Fuel Quality and Combustion Behaviour


The contamination of woody biomass with mineral soil might have a substantial impact on their combustionbehaviour. Due to careless operation during fuel production, high levels of mineral soil might be added to the fuels,e. g. as a part of the silvicultural logging process. This may lead to unwanted effects on the combustion such as highemissions, corrosion or slag formation. Thus, the aim of this study was to evaluate the combustion behaviour ofcontaminated wood pellets including the identification and evaluation of potential damages to boilers (e. g. corrosion)and of the environmental impact (e. g. emissions).

Integrating Pcm-Based Thermal Energy Storage on Top of Wood Stoves: Concept and Cfd Modelling


Applying latent heat storage (LHS) for small-scale batch combustion stoves is a promising concept to exploit thephase change materials (PCMs) properties. With typical thermal efficiency of 70 to 80 % at nominal load, modernwood stoves often produce more heat than actually required to heat up the house, especially in highly-insulatedbuildings. An effective LHS system, using a PCM with melting temperature within 100-150 °C, can flatten out thepeak heat release to the room by storing it as latent heat. The investigation aimed at exploring the possibility todesign a compact and durable LHS system with the ability to store a significant part of the heat produced duringbatch combustion and to effectively and slowly release the stored heat to the room after the end of the combustionduration.

Statistical Analysis of Vegetables Oils Combustion in a Low-Pressure Auxiliary Air Fluid PulverizationBurner, in Order to Establish Optimal Operating Conditions.


The use of vegetables oils as fuels with heating purposes, in conventional burners, is a viable alternative to fossilfuels [1-3]. In this context, it is necessary to know the factors affecting to the combustion process to achieve thelowest polluting emissions and the utmost combustion efficiency. In this work, the combustion of three vegetable oils; refined soybean oil (ReSyO), refined rapeseed oil (ReRpO) andraw rapeseed oil (RaRpO), is performed in an emulsion (air-fuel) burner. Polluting emissions (CO, NOx, CxHy) andcombustion efficiency (?) which have been obtained by modifying two adjustable parameters of the burner,secondary air flow and fuel flow, have been studied. Finally, an ANOVA of the results obtained was carried out. Theaim of this work is to look for trends between the operational parameters of the installation and the results ofcombustion.

Investigations on Combustion Air Pre-Heating in Small Scale Biomass Heating Units


The presented project was pursuing the development of a combustion air pre-heating system in a small scale woodchip combustion plant, using waste heat from flue gas to reduce carbon monoxide emissions and improve efficiency,even for difficult fuels. In order to determine the optimal combustion air distribution (primary vs. secondary air) acoupled DEM/CFD simulation technique was used investigating different air configurations. Subsequent combustiontrials were carried out with novel measurement techniques, applied to a retrofitted 400 kWth wood chip heating unit.In particular, the spatially resolved heat flux and the vertical velocity of the gas flow in the combustion chamber weremeasured with customized measuring probes. Moreover, the combustion air/flue gas temperature and the flue gascomposition were characterized at multiple points. The project was funded by the Federal Ministry of Food and Agriculture (BMEL), FKZ 22007715.

The Impact of Variability on Repeatability in Domestic Combustion Stove Testing and Confidence inEmission Factor Results


Popularization of fuelwood and solid fuel has contributed in increased urban population affecting both climatechange and human health. Emission Factor values are applied as a method of determining the level of specificpollutants associated with specific fuels/stove devices. Variability in fuel may lead to inconsistencies in emissionconcentrations requiring additional testing. The following work aims to establish how variables associated with bothfuel properties and stove operation can affect emissions and how may experimental results are required to minimizeerror for improved results confidence.

Technology Mapping of Market-Available Small-Scale Combustion Appliances


A broad range of different biomass combustion appliances dedicated to domestic heating is available on the market.Depending on the technology the impact of varying properties of biomass fuels on slag formation and emissionrelease may vary. Aspects as the design of the grate section and the selection of individual boiler components aswell as operational settings determine the applicability of biomass fuels. Apart from fuel properties also the fuel loadon the grate, residence time, air distribution and geometry of grate and combustion chamber affect the degree ofslag formation and emission release. Characteristic numbers determined by means of constructional measuresenable a systematic comparison and – in a further step – an assessment of combustion appliances. In this workspecific characteristic numbers were specified and applied to compare technological aspects, which willprospectively allow investigating the technological influence on the combustion performance.

Emissions Reduction in a Household Biomass Cook Stove with a Simple Modification


Air pollution is the world’s largest single environmental health risk. Globally, 3.8 million deaths were attributable tohousehold air pollution in 2016, almost all in low- and middle-income countries. This is mainly due to cooking withsolid biomass in substandard traditional stoves, as 2,700 million people (38 % of world population) rely on thismethod. These traditional processes produce very high emissions of unburnt products as CO, volatile organiccompounds (VOC), PAHs, and soot, which lead to several health problems.One possible solution to address this situation is to re-engineer the employed devices and methods, with conceptssuch as the top-lit updraft gasifier (TLUD). In this work, a TLUD-based cook stove employed in Uganda is furtheroptimized in order to reduce its emissions. The conducted simple modification increases the residence time of theflue gas in sufficiently high temperatures for combustion. In this way, the CO emissions are reduced from 8.5 to 2.2gCO/MJdel. The obtained 75 % reduction in CO emissions can be therefore achieved with simple measures. Theseconcepts can then lead to significant health improvements for biomass cook stove users.

Today, state of theart wood stoves applies staged air combustion. This air-staging is the main reason that new wood stoves have muchlower levels of particulate emissions than older ones. An optimized two-stage combustion should also be able tosignificantly reduce the NOx emission level. So far, however, this has not been emphasized sufficiently when itcomes to wood stoves.As a step towards achieving a significant NOx reduction by optimized staged air combustion, it would be interestingto assess the reduction potential by modelling based tools. This should be done by using detailed chemical kineticsin ideal reactors, and ultimately also in computational fluid dynamics (CFD) simulations. In this work a transientmodelling approach using ideal reactors is applied.A number of key results will be presented, showing the current status with respect to NOx emissions andimprovement potentials based on modelling results. Recommendations will be given as well.

Energetically Self-Sufficiency with Heat on Basis of Wood Chips from Src - From Conception to Realizationof a 500 Kw Biomass Heating Plant at the Atb


The use of biomass from short rotation coppices (SRC) for energy in rural areas is connected to many advantagessuch as an additional income for farmers, self-sufficiency with heat at competitive prices, a reduction of greenhousegas emissions and an increase ecosystem services in agriculture. There is a high demand for energy in agriculture,e.g. for heating of farm buildings as well as for drying of agricultural products. Despite of these benefits, examples ofself-sufficiency with heat on basis of wood from SRC are rarely to be found in practice. The lack of knowledge aboutproduction technologies as well as high investments cost for biomass boilers and local heating networks are some ofthe reasons for this situation. To overcome these obstacles, a project demonstrating the self-sufficiency with heat onbasis of a 500 KW biomass boiler fed with Wood from SRC has been developed and realized at ATB. More than40% of the heat demand of the ATB will be covered by heat from SRC, representing a reduction of the annualheat-related CO2 emission by 36%. Despite of the high investment costs for the new system, a reduction of thecurrent heat price by approx. 25% has been calculated.

Control of Particle Emissions from Small Scale Wood Combustion Facilities


Biomass combustion results in particulate and gaseous emissions. The aim of the current work is the study oflong-term operation stability and efficiency of reduction of particulate emissions from exhaust gases using compactelectrostatic precipitators. First, the tests are carried out for wood chips from leaf-trees, from needle-trees and froma mixture of leaf- and needle-trees. Second, the test are carried out for “non-stop” and “stop-and-go” combustion ofmixed wood-chips inn the boiler. At the same value of power consumption for particle charging, the quality ofwood-chips strongly influences on the efficiency of reduction of particulate emissions. The “stop-and-go” combustionof mixed wood-chips is characterized by increase of carbon concentration in the fly ash, collected in the precipitator.About 90% of the mass of wood ash remains inside of the combustion facility and ca. 10% flow out from thecombustion facility. Compact ESPs are characterized with mean particle mass collection efficiency of ca. 75%. Therecommendations for enhancement of control of particulate emissions from small scale wood combustion facilitiesare developed.

Monitoring of Nox Emission Depending on Wood Chip Quality in a Medium Sized Biomass CombustionPlant


The medium combustion plant directive (MCPD) is now being transferred into German law for combustion plantswith a thermal heat output from 1 to 20 MW. Within this regulation, flue gas emissions (CO, NOX and PM) will belimited to certain values depending on the thermal heat output of the plant. Especially for combustion plants with aheat output from 1 to 5 MW there is a lack of knowledge concerning the variability in the formation of NOX emissionsas caused by the usual variation of fuel properties through out a complete heating season. The major fuel parameterin focus is the nitrogen content in the fuel itself. But other important parameters are also monitored, such asmoisture content, ash content, bulk density, particle size distribution and element content from elementary analysis,as there may be correlations or impacts on the level of CO (carbon monoxide) emissions.

Reducing Exhaust Emissions in Small Gasoline Engines Using Biofuels: a Case Study of an Off-RoadVehicle Design for Collegiate Competitions


The development of a collegiate competition off-road vehicle is described. For these competitions a small gasolineengine is specified as one of the requirements for the design and the vehicle is built around it. For this case study,exhaust emissions will be experimentally determined when operating the vehicle with the base required gasolineengine. Then emissions will be measured with a modified version of the base engine operating on the biofuel. Comparisons will be made to evaluate overall emissions reduction. These results should be indicative of emissionsreductions possible in other applications.

Modeling Pyrolysis Kinetics for Biomass Particles of Different Morphologies Relevant for SuspensionFiring Conditions


The overall aim of this project is to increase model predictions for computational fluid dynamics (CFD) simulations ofsuspension firing of biomass particles. Biomass particles are typically elongated, and modeling them as isothermalzero dimensional (0D) particles is not sufficiently accurate. On the other hand a two dimensional (2D) modelincluding temperature gradients and particle morphology is typically too computationally heavy to be applied to themillions of particles present in a CFD simulation of a suspension fired facility. The approach presented herecombines the advantages of a 2D and a 0D model for particle pyrolysis modeling. In this work the 2D model is usedto describe the effects of morphology on particle temperature and conversion as a function of aspect ratio. Thearrhenius parameters of a 0D model are then adjusted to match the 2D model to account for the effects of particlemorphology on the pyrolysis process. Both models are compared to literature data.

Interchangeability Analysis of Biogas and Hydrogen Blends


The future gas supply will gradually become more dependent on renewable fuels, particularly biogas and hydrogen.Because of this, the composition variability in the grid will increase and the interchangeability between fuels must beensured. An adequate interchangeability of gases can only be achieved if combustion performance does notsignificantly change when the fuel composition varies. The integration of biogas and hydrogen in the future gridpresents a new paradigm, where fuels composed mostly by CH4, CO2 and H2 replace applications that currentlyuse natural gas. Therefore, this work intends to test the response of current criteria to the interchangeability ofCH4/CO2/H2 blends. The aim is to determine whether current criteria suffice as an interchangeability method forCH4/CO2/H2 blends or new methodologies are required for this new generation of renewable fuels.

Cfd Deposition Modeling of Fly Ash Particles on Biomass Fired Boilers


Detecting and preventing ash deposits in boilers is critical for improving their availability in terms of working hoursand for avoiding outages and related costs. To accomplish this goal, a useful, accurate and reliable computationaltool for predicting and preventing fouling problems in boilers that fire troublesome biofuels is presented. Our modeluses inertial particle deposition in a fully developed turbulent boundary layer using the Lagrangian stochastic particletracking method of quadrant analysis. The model considers the condensation of alkali salt vapors as well as theimpact mechanism of coarse sticking particles in fluegas. A reference viscosity based on kinetic energy is used inorder to settle proper sticky limits. Finally, the deposition modeling is compared to deposit probe measurements inexisting boilers where the deposition wall temperature has been controlled.

Investigation of the Combustion Environment Generated from Combined Biomass Fuel Categories


The future of renewable energy generated from biomass combustion is reliant on using a wider range of fuelsincluding cheaper, less “clean” biomass. However, as with conventional fossil fuels, the combustion of biomassresults in the formation of corrosive species, which can result in fireside corrosion. To evaluate the post-combustionchemical environment generated, over 120 biofuels have been sorted into four fuel categories. MTDatathermodynamic modelling has then been used to calculate key post-combustion condensed and gaseous phasesthat could develop in the flue gas of a biomass combustion plant for these different fuel categories. Trace elementshave been shown to impact compounds commonly linked to fireside corrosion; as such, the role of these traceelements on fireside corrosion mechanisms merits further study. This analysis also makes it possible to linkchemical species that influence fireside corrosion to different fuel categories, and hence compare the relativesusceptibilities of plants firing these fuel categories.

The Effect of Adding Ethanol on the Ignition Properties of Fast Pyrolysis Bio Oils


In this paper, the ignition behaviour of droplets composed by crude FPBO and FPBO/EtOH blends at normalpressure is discussed. The tests were carried out, in a closed single droplet combustion chamber with opticalaccesses, on droplets of diameter in the range 0.8 mm -1.4 mm. FPBO/EtOH blends with percentage of alcoholvarying between 5 % v/v and 50 % v/v were tested. To analyse the effectiveness of the addition of ethanol on theignition properties of FPBOs, the study was carried out on the crude FPBO used to form the blends as well as onesterified FPBOs characterised by low water content and TAN values. Finally, a deeper understanding of the ignitionbehaviour was gained by comparing the experimental data with the numerical results obtained by 1D modelling ofthe evaporation and ignition of droplets of crude FPBO and blends EtOH/FPBO.

Switchgrass Harvest Timing and Method Affect Biomass Yield and Quality in the US Great Lakes Region


Weather conditions during post senescence fall switchgrass (Panicum virgatum L.) harvest in the US Great Lakesregion often do not facilitate proper field drying of switchgrass prior to baling. In order for a cellulosic biofuelproduction system to be feasible, a switchgrass biomass harvest system that facilitates timely harvest for farmers,maximizes harvest yield, minimizes dry matter storage loss, and maximizes switchgrass winter hardiness isnecessary. This study compared a dry bale harvest method with a direct cut chop and ensile harvest method acrossthree (early, mid, and late) fall harvest timings. Switchgrass yield, quality and stand survivability, were evaluated.Biomass yield was maximized during an early fall harvest timing using a direct chop and ensiling harvest method.However, neither harvest method consistently produced a higher quality feedstock than the other. Overall, the datasupport a hypothesis that direct chopping and ensiling will maximize harvest yield, minimize environmental impactsand would potentially be most profitable and sustainable for switchgrass biomass feedstock production in the USGreat Lakes region.

Integrating Miscanthus Into Agricultural Practice: How Can Miscanthus Best be Cleared from the Field atthe End of Its Lifetime?


Miscanthus is a promising perennial crop for bioeconomy. However, if its cultivation area is to be extended, the fastand efficient clearance of the crop at the end of its lifetime will become of major importance for farmers, asresprouting may impair a subsequent crop. In the small number of studies that have dealt with this subject, theclearance of miscanthus was performed via glyphosate application. As the future of glyphosate is uncertain, otheroptions for the clearance of miscanthus need to be analysed.The objective of this study was to identify suitable subsequent spring crops (ryegrass, maize, barley, rapeseed) thatfacilitate miscanthus clearance without glyphosate application.

Flexible Hybrid Process for Combined Production of Heat, Power and Renewable Feedstock for Refineries


This paper is focused on the developemnt of a flexible and integrated hybrid process, which combines electrolysis ofwater with gasification of biomass and catalytic liquefaction. This process produces heat, power and an intermediateenergy carrier (FT wax), which can be refined to transportation fuels using existing oil refining equipment. TheFLEXCHX process can be integrated to various combined heat and power production systems, both industrial CHPsand communal district heating units. In the summer season, renewable fuels are produced from biomass andhydrogen; the hydrogen is produced from water via electrolysis that is driven by low-cost excess electricity from thegrid. In the dark winter season, the plant is operated only with biomass in order to maximize the production of themuch needed heat, electricity and FT wax. Most of the invested plant components are in full use throughout the year,only the electrolysis unit is operated seasonally.This paper outlines the results of the concept development studiescarried out during the first 12 months of the three-year-long H2020and decribes the 0.5 MW pilot gasification plantused in teh project.

Advantages of Fountain Enhanced Regime for Biomass Steam Gasification in a Conical Spouted BedReactor


Biomass gasification processes have considerably gained attention for the sustainable production of syngas whichcould be used as fuel or as an intermediate product in the production of other fuels and chemicals. However, themajor challenge of this process is still the high level of tar presented in the gas, which hinders the improvement of itsindustrial viability. Within tar removal strategies, the design of the gasifier is usually the first measure adopted. Thus,certain modifications were introduced in a conventional spouted bed to change reactor hydrodynamics, with the mostsignificant one being the confinement of the fountain.

Building Value Chains for Large Scale Ft Production


The present work focuses on two different routes for the production of bio-based FT fuels within the EU fundedBECOOL project. These routes are part of the large value chain analysis for the production of bio-based FT-fuels.Biomass considered are Fibre Sorghum, Arundo Donax and Eucalyptus. The first route is based on the conversion of feedstock in an indirect gasifier, where co-products such as BTX areobtained and product gas is processed to produce a syngas suitable for FT production. The second route is based on the combination of pyrolysis with gasification. In this case slow oxidative andintermediate pyrolysis processes are used to produce bio-intermediates (char and bio-oil) which are combined tocreate a slurry obtained from the biomass feedstock. In the gasification step the slurry is converted into a gassuitable for FT production. The paper will present both steps and discuss how these will fit in a value chain towards advanced biofuels.

Comparison Of Batch And Pilot Scale Continuous Tubular Autohydrolysis Pretreatments Of FourAgroindustrial Residues


Pretreatment of agave bagasse (AG), corn stover (CS), sugarcane bagasse (SC) and wheat straw (WS) in alab-scale batch (LB) and pilot-scale continuous tubular (PC) reactors at 180 °C and 20 min residence time wereinvestigated. For LB and PC, xylan removal by autohydrolysis was in the ratio of 20.2%-58.0% and 57.3%-83.1%,respectively. High glucose and xylose production were achieved during enzymatic saccharification. For example,comparing LB and PC pretreated samples sums of glucose and xylose release during saccharification, SC (10.5 g/Lvs. 13.2 g/L) and WS (18.8 g/L vs. 21.7 g/L) were statistically different, unlike AG and CS (P0.05). These results willcontribute to the assessment of pilot-scale systems supporting the design of demonstration/commercial facilities.

Component Decomposition during Simultaneous Hydrothermal Milling Pretreatment for LignocellulosicBiomass


Recently, using lignocellulosic biomass for bioethanol production is required, because of environmental issues anddepression of fossil fuels. As is well known, lignocellulosic biomass needs pretreatment before hydrolysis forobtaining high sugar yield. Various pretreatment technologies, including hydrothermal pretreatment, acidpretreatment, and pulverization pretreatment, have been studied. Above all, pulverization and hydrothermalpretreatments are environmentally friendly and allow to reduce the cost of processing. However, just pulverizing isnot enough to obtain high glucose yield and high energy consumption becomes a new problem. To circumvent thisproblem, we conducted pulverization and hydrothermal pretreatment simultaneously using a laboratory scale diskmilling apparatus which could be operated under hydrothermal conditions. In this study, we conducted pulverizationpretreatment under hydrothermal condition and then analyzed solid and liquid part obtained after pretreatment forcomponent decomposition of eucalyptus. As a result, most of cellulose was not decomposed and lignin andhemicellulose were decomposed during pretreatment. Decomposed product in liquid phase did

Integration of Cellulosic Biomass to Biofuel Conversion in the Steel Industry


The blast furnace (BF) process is the most energy efficient way to reduce iron ore to primary steel thanks to its largescale and low thermal losses. However, as it is operated on fossil coal, novel approaches are required in order todrastically reduce its carbon footprint in an economic way. To reach this goal, ArcelorMittal is building a large demonstration plant which integrates two innovative approaches :pre-treatment and injection of cellulosic waste streams to create a biogenic feedstock for renewable fuel injectionand fermentation of the carbon monoxide waste gas into ethanol to avoid the incineration of the carbon monoxide.The use of the bio-ethanol in other sectors (transport, chemicals) will displace fossil oil or natural gas. A first of akind plant is currently under construction at ArcelorMittal in Gent in which biocoal will be produced from torrefactionof wood waste. The key objective of this project is to validate how this biocoal technology can be used in aproduction representative environment which is a large-scale industrial steel mill.

Pilot-Scale Fractionation of Fast Pyrolysis Oil to Facilitate the Development of Biobased Products


An innovative biorefinery concept is developed in the EU funded Bio4Product project. It combines a short thermaltreatment at elevated temperature (fast pyrolysis) followed by a low temperature fractionation of the mineral free,liquid product (FPBO) that keeps the key chemical functionalities intact in separate, liquid, depolymerized fractions.These pyrolytic fractions consist of components derived from the de-polymerization of cellulose, hemicellulose andlignin. The application of the pyrolytic fractions will be demonstrated in a number of end products such as roofingmaterial, phenolic resins, sand moulding resins, and engineered wood and natural fibre reinforced products. A 3ton/day fractionation plant has been constructed to enable large scale product development.

Pyrolysis of Lignin: Effects of Molecular Weight and Bond Type


Lignin is an abundant natural aromatic polymer, which provides structural strength to plant cell walls. Generally, it isburned as a low-value fuel. However, lignin being aromatic in nature might be a potential source for the production ofmono-aromatics (BTX type) and other value-added chemicals. Depolymerisation of lignin via fast pyrolysis is widelystudied over a wide range of temperature and in different setups. Slow heating rates (in TGA) and online detection ofvolatiles (e.g. in Py-GC/MS), offers limited information about true primary products because a major fraction of thepyrolysis products are composed of large molecules and remain therefore undetected. The goal of current work is toinvestigate the primary products, underlying primary reactions and the behaviour of different inter-unit linkages (e.g.?- O-4, ?-?, ?-5) under minimal mass and heat transfer limitations.

E4bioframe: Extra Energy Efficient Exploitation of Biomass for Fuels, Rubber, Asphalt, Materials andEnergy


The Dutch national project E4BIOFRAME is conducted as an activity along the thermochemical horizon towardsfunctionalized aromatics from lignin and lignin-rich biomass sources in the framework of the BIORIZON sharedresearch center in the south of the Netherlands. Regarding the pyrolytic valorization of lignin and lignin-rich biomass, it is thought that the collection of pyrolysisvapors in separate fractions offers interesting opportunities for valorization, e.g. towards biobitumen, biorubber andspecific marine biofuels. For these high market volume – medium market value products, earlier work has revealedthat the application of lignin as such (so without derivatization / modification) was not successful. Consequently, itwas deduced that (partially) depolymerized fractions from lignin and/or lignin-rich residues would possibly be usablebecause of lower molecular weight and/or higher reactivity and/or better miscibility with their petrochemicalcounterparts.

Environmental Application of Polymer/Biomass-Derived Biochar


Disposal and treatment of agricultural waste have been intensively studied in the last decades. Recently, pyrolysis ofbiomass wastes was proposed as an alternative process for developing alternative energy in response to climatechange. Pyrolysis is not only used to treat the biomass waste, it can also be used to produce a solid by-product(biochar) and reusable energy such as heat, bio-oil, and syn-gas. So far, many studies have been conducted on theuse of biochar as an alternative sorbent to immobilize toxic metals and organic compounds in environmentalapplications. However, the sorption capacity was still less than that of activated carbon due to the low carbon contentand small surface area. In the present study, co-pyrolysis of polymer and biomass wastes was investigated as anovel method for waste treatment and synthesis of enhanced biochar.

Feedstock Characterisation and Slow Pyrolysis Kinetic Study for the Production of Char - GreencarbonProject


The European GreenCarbon Project aims to develop engineered pyrolysis processes, which can be taken to market,utilising dry bio-waste sources with the view to produce tailor-made biomass-derived carbons. The kinetic resultspresented in the literature shows considerable variation across the different methods with no conclusion as to whichgives the most accurate results for each feedstock. A characterisation and kinetic study of the GreenCarbonfeedstocks will be undertaken to understand the optimal operating conditions during slow pyrolysis and to developand validate a comprehensive pyrolysis model. The characterisation will include a proximate and ultimate analysis,followed by thermogravimetric analysis (TGA) experiments to analyse the kinetics of the thermal degradation of thebiomass feedstocks. The results from this study will be the parameters to predict the behaviour of the biomassduring pyrolysis; the variability of the pre-exponential factor and activation energy for the thermal degradation of thefeedstock.

Therefore, a conceptual framework is developed to understandthe feasibility and associated cost of co-processing bio-oil with conventional crude. The techno-economicassessment models were developed using the process models to assess the added cost of blending bio-oil atdifferent co-processing ratio with crude oil for different pathways. Process models included rigorous simulation inAspen HYSYS for co-processing of hydrodeoxygenated bio-oil (from pyrolysis and hydrothermal liquefaction) withcrude oil. There is a good agreement between the simulation and experimental data and it shows a promisingmethod for production of fuels with renewable contents. The bio-carbon content was assessed and compared withthe current business scenario of drop-in fuels with crude oil.

Natural Minerals fFor In-Situ Catalytic Pyrolysis of Pecan Nut Shells


In this work, cheap, locally-produced minerals were used as catalysts for in-situ catalytic pyrolysis of pecan nutshells. The effects of both the mineral presence and mineral calcination were evaluated. Mineral presence wasobserved to enhance pyrolysis, while calcination improved the process performance even further. Higher biogasyields were observed, while also formation of less-oxygenated compounds was found in the bio-oils, especially whencalcined catalysts were used for pyrolysis. For the biogas, hydrogen production was strongly promoted with thepresence of calcined CaCO3.

A Predictive Model for Fast Pyrolysis of Cylindrical-Shape Woody Biomass with a Size Distribution


Unlike other solid energy feedstocks (e.g., coal and oil shale), lignocellulosic biomass feedstocks reveal a multiscale(with variation over multiple orders of magnitude) structure, which is changing during degradation, renderingfundamental prediction of properties and product distributions a challenge. This motivation of this research is toovercome the technical limitations of the traditional numerical models (e.g. computational fluid model) byincorporating the impact of particle size distribution and particle shape on mass/heat transfer during biomass fastpyrolysis. In this study, a Population Balance Model (PBM) and distributed activation energy model (DAEM) coupled model forbiomass fast pyrolysis is developed and presented.The model framework also enables the study of criticalparameters in biomass fast pyrolysis such as reaction rate, temperature and feeding composition/size of biomassfeedstock, which demonstrates its promising potential for the design of pyrolysis reactors and determination ofoptimal feedstock particle sizes.

Bio-Crude Oil Production from Coffee Ground by Fast Pyrolysis Combined with Stabilization Process


Coffee ground is considered one of the promising biomass resources due to the growth of coffee consumption andhigher calorific value from its larger carbon content and lipid component. In the present study, bio-crude oil wasproduced from coffee ground in a tilted-slide reactor. The higher heating value of the biocrude-oil was 6100 kcal/kgwhich is about 50% larger than that of woody biomass. But the viscosity of bio-crude oil from coffee ground wasquite larger than that from woody biomass, and the viscosity increased during the storage. It is known that theaddition of solvent, e.g., methanol or ethanol can decrease the viscosity of bio-crude oil. Because the stabilizingreactions can be further promoted at high temperature, ethanol was injected into the primary condenser where thehigh-temperature volatiles from the fast pyrolysis were condensed by bio-crude oil spray. The characteristics of thebio-crude oil by on-stream ethanol injection were monitored and compared with the original bio-crude oil.

Pyrolysis of Wood in Rotating Tumbler


Wood pyrolysis produces gases and char that could be used respectively for Combined Heat & Power productionand soil amendment (bio-char concept). In this work, the pyrolysis reactor is a novel continuous rotating tumblerreactor that mixes wood pellets and hot steel balls. The novelty of this reactor is represented by the hot steel ballscontained in the granular bed, which enhance granular conductivity and transfer heat directly to the wood phase. This study aims at modeling this reactor; however, due to the originality of the technology, a novel model has to beintroduced to take into account the complex mechanics involved. For this reason, DEM modeling is used to simulateaccurately the bed composed by wood pellets and steel balls. With the results from the DEM modeling [2], acombination of ideal reactors able to simulate the real case is found; it is then possible to write a Matlab 1D code totake into account pyrolysis reactions kinetics coupled with radiative, convective and conductive heat transferbetween steel balls, wood/char particles, gases and reactor wall. The impact of these different phenomena isassessed through a sensibility study.

Pyrolysis and Pressure: New Insights Based on Fixed-Bed Experiments in Chemical Regime


The effect of pressure on biomass pyrolysis has been studied for 40 years since the pioneering work of Antal andco-workers. It was shown that pressure induces an increase of char yield due to secondary reactions that transformvolatiles into char. But contradictory data are presented in the literature on the effect of pressure. In this study, thepyrolysis of oak wood has been studied in a fixed bed reactor system. The diameter of the reactor, the sample massand the heating rate were chosen to remain in chemical regime and to lessen the thermal effect related toexo/endothermicity of the pyrolysis reactions that depends on pressure. To better understand the effect of pressure,the parameters which can also act on the residence time of the pyrolysis vapours in the reactor - that are the gasflow rate, bed mass and bed density - are well controlled. To better understand and explain the effect of studiedparameters, our methodology is based on the characterization of char yield, composition and morphology (surfacearea, SEM, Raman spectra). The yield and composition of condensable vapours and gases are also determined.

Linking the Monitoring and Evaluation of Sustainable Bioeconomy Development with the CountryPerformance in SDG Reporting


Bioeconomy has been proposed as a strategy to overcome many global and national challenges, from climate actionto income diversification in rural areas. Yet, monitoring and evaluation of bioeconomy is crucial to ensure itsdevelopment in a sustainable manner; thus, the ultimate goal is not to measure the bioeconomy per se, but itssustainability. Ideally, the monitoring and evaluation should focus on the quality and impact of bioeconomydevelopment, rather than merely its achievements. One way to ensure sustainability of bioeconomy strategies wouldbe linking its reporting with internationally-agreed targets of Sustainable Development Goals of the United Nations(SDGs). Although there are case studies, scientific articles and technical reports in literature of bioeconomy andother related strategies (e.g. green economy, circular economy) and their links to SDGs, the complete picture on thisheterogeneous literature is missing. The objective of this work is to lay out the opportunities regarding monitoringand evaluation of bioeconomy and bioeconomy-related concepts to aid the countries report their status on attainingSDGs.

Self-Assessment as an Effective Measure of Waste Management to Improve Recycling Behavior atConsumer Level


The objective of our study is to identify solutions and methods on how to reduce food waste at consumer level.Within our study, we apply the method of self-assessment in a gastronomic context in addition to existing operationalwaste management systems. To automate the self-assessment process, we developed a software applicationconnected with an electronic scale. This offers the possibility to document disposals directly at source and to receivea real-time feedback of the wasted food. We installed this waste management tool in more than 20 differentgastronomic facilities and achieved in most cases an improvement compared to the status quo. In the meantime, weare developing an online version of this monitoring instrument in order to enable a larger usage of this application. Inour oral presentation, we will give a brief insight in the findings of our study. Furthermore, we will discuss chancesand limitations using this method to reduce food waste in large scale.

Increasing Biofuel Production from Wastes & Residues to meet Transport Energy Targets


The UK Department for Transport (DfT) recently announced its intention to raise the targets of the RenewableTransport Fuel Obligation (RTFO), paving the way for future growth of the UK biofuels industry. DfT also have longterm strategic aims for decarbonising the heavy goods vehicle and aviation sectors where biofuels are expected toprovide a contribution. Alongside these targets the Government has imposed restrictions, limiting the contributionsby crop-based biofuels. As a result there will likely be significant rises in demand for non-crop feedstocks, such aswastes and residues. There are consequently many questions about future availability of biomass feedstocks for thetransport sector, what characteristics available feedstocks may have, and how they can be best used to producebiofuels. This presentation will provide an overview of a research project undertaken by the University of Manchester, AstonUniversity and Cranfield University that aimed to address each of these areas of concern. We carried out biomassresource modelling, feedstock charterisation analysis and techno-economic analyses to evaluate the feasibility ofgrowing the UK biofuel from waste sector.

Operational Experience of the Bioliq® Pilot Plant for Synthetic Fuel Production


Ten years ago, the fast pyrolysis plant as the first part of the bioliq pilot plant was mechanically completed atKarlsruhe Institute of Technology. Since then, the process chain to produce synthetic gasoline from lignocellulosicbiomass was further completed by high pressure entrained flow gasification, high pressure hot gas cleaning, onestage methanol/dimethyl ether and gasoline synthesis plants. This pilot facility with load capacities varying between 2and 5 MWth is used for technical demonstration and as large research platform for optimization and further technicaldevelopment of the individual technologies as well as of the combined process. Another important task is to providetechnically relevant syngas quantities for testing of syngas purification and synthesis processes as well as ofadequate biofuel quantities for application test such as engine-test benches or car driving tests.In a number of presentations and papers published so far, the focus was mainly on the individual process steps oron the concept and design of the pilot plant. Here an overview on experiences, lessons learned and improvementsalong the whole process chain is compiled.

Evaluation at Laboratory Scale of Nickel-Catalyst Pellets for in Situ Tar Steam Reforming in BiomassThermochemical Conversion


Ceramic-catalytic candles represent an innovative approach to syngas cleaning, as they allow an in in-situ (in thefreeboard of the fluidized bed gasifier) operation which simplifies downstream cleaning and conditioning treatmentsof the raw syngas, with respect to the current practice of low temperature tar scrubbing.Recently, in order to avoid practical constrains related to the nickel-impregnation procedure, a simpler concept wasproposed: a plain ceramic candle (filter) filled with pellets of a commercial nickel-based reforming catalyst. However,the complexity and the high number of variables of a gasification process hinders a deeper insight in the intrinsicbehaviour of the catalyst inside candles.The study presented here aims to fill this gap: (i) experimentally investigating the same nickel-based catalyst pelletsby using a bench-scale packed bed reactor rig for steam reforming of tar key-compounds: (ii) modelling steamreforming of tar by a lumped approach, considering tar as a unique carbonaceous pseudo-compound whose carbonatoms (Ctar) are involved in a steam reforming reaction (Ctar + H2O ? CO + H2) accompanied by WGS.

Agroclimatic Zoning of Straw Removal and its Impacts on Sugarcane Yield


The green cane harvesting system has resulted in the deposition of large amounts of straw (tops, green and dryleaves) on the soil surface after harvesting. The straw has been considered very attractive with the growing globaldemand for bioenergy, once it has a significant potential as feedstock for second-generation ethanol production andbioelectricity cogeneration. However, there are some trade-offs associated with straw removal because the strawmulching on the soil results in some benefits in terms of soil water storage, nutrient cycling, soil erosion control, soilbiodiversity, soil carbon stocks, soil temperature and weed control. The objective of this study is to define thesuitability for the straw removal based on climatic data aiming to benefit sugarcane yield in the BrazilianCentre-South region. This climatic spatial analysis will allow to create a map with straw removal suitability classes,based on multicriteria assessment techniques, and will support the construction of guidelines for the sector, whichwill estimate the amount of straw that can be sustainably removed without impair crop yield for each region.

Variable Biofuel Demand: Potential Impacts on Food Security, Agricultural Productivity and ILUC


There is much debate on the potential and actual impact of biofuel policy and production on crop production andfood availability, resulting in a series of distinct but opposing views. While the debate so far has not led toconvergence, the call for a more balanced view is emerging. Moreover, there is a need for development of policyoptions which can help to contain and restrict potential negative impacts of biofuel production. Varying the demandfor biofuels could potentially be the solution. This project evaluates the perspectives of introducing a variabledemand approach in bioenergy policy aiming to stimulate investments and enhancing efficiency in crop productionwhile limiting competition with food in years of reduced crop availability. The opinion of over fifty international expertsin the field of bioenergy policy, technology and sustainability is presented in a detailed and quantified way. It providesinsights on where research should be directed to establish effective policies that enhance biofuel production whilelimiting potential negative impacts on food availability.

Bioenergy Strategies to Address Deforestation and Household Air Pollution in Western Kenya


Over 700 million people in Africa are expected to continue relying on charcoal and firewood by 2040. In WesternKenya, inefficient cooking practices persist as a major cause of air pollution, disease and premature deaths. Thisresearch applies a modelling approach that combines the Long-Range Energy Alternatives Planning (LEAP) systemand the Life-Cycle Assessment tool Simapro 8.5 for analysing biomass strategies for the region. The present systemanalysis shows the effect of biomass strategies on the reduction of wood fuel harvesting and short-lived climatepollutant emissions, achieved by the replacement of traditional cooking fuels/technologies by novel alternatives by2035. In the Kisumu County, the deployment of pellet and biogas fired cookstoves will reduce the harvesting of woodfuel from the natural forests and the net CO2eq emissions by over 90%, as compared to the BAU scenario. Thepolicy measures will contribute to reduce the emissions of PM1 and BC by up to 60 and 40%, respectively. Theenvironmental externalities on health will be significantly reduced, and socio-economic benefits can be capitalised interms of innovation systems to communities and industries

The Connection Between Cyclic Operation and Emissions of a Biomass Heating Plant


The economic efficiency is a decisive factor in the realisation of biomass-fuelled heating plants. In many cases, costconsiderations are therefore more important than the efficient dimensioning of the installed capacity. Plants withhigher power output are often operated in real operation in a cyclic manner in order to cover a low heating load incombination with a heat accumulator. In such an operating mode, however, the furnace rarely reaches a stationaryoperating state. This leads on the one hand to low efficiency in fuel utilisation and on the other hand to increasedemissions. This behaviour can be examined in a long-term study with several heating plants. The aim of this projectis to provide evidence of how strongly cyclic operation and increased emissions correlate in real plants.

Production and Characterization of Biochar from Agricultural Residues Containing Plastics


Since agricultural biomass waste contaminated with agricultural plastics is a prominent waste stream in intenseagricultural areas and complete separation of the plastic residues from the biomass is not always straightforward,there is a high possibility to use agricultural biomass and agricultural plastic wastes together in a single stream toproduce valuable products via recycling. Therefore, applying pyrolysis for recycling of agricultural biomasscontaminated with agricultural plastic materials seems to be a valid approach to address the problem of agriculturalplastic wastes. Hence, the effect of low levels of agricultural plastics in the biomass on the mass balance andproduct composition of pyrolysis products was examined during this study.

Production of pyrolytic products from palm kernel cake using fast pyrolysis


Palm kernel cake (PKC) was pyrolyzed in a bench-scale pyrolysis fluidized bed reactor equipped with charseparation system and bio-oil recovery system. Fast pyrolysis was carried out under the various reactiontemperatures to investigate behavior nitrogen content of each pyrolysis product. The maximum yield of bio-oil fromPKC was approximately 63 wt% at the reaction temperature of 402 ºC. The nitrogen compounds in bio-oil wereconfirmed by GC-MS. The main nitrogen compounds of bio-oils were pyridine and actamaide. The nitrogen contentof the bio-oil increased until 500 ºC and decreased after 550 ºC. As the reaction temperature increased, the nitrogencontent of char was decreased and the nitrogen content of gas was increased.

The fraction ofbiochar with particle diameter less than 50 µm was used to form the slurry. The studies of evaporation andcombustion of drops of slurry were carried out in a single drop combustion cell, provided with optical accesses. Atthe center of the cell it is placed a bare thermocouple junctions (d = 75 µm) to which the drop is suspended bymeans of a microsyringe. The thermocouple provided the temperature of droplets during the different phases ofdroplet evolution. A high speed digital imaging systems was used to follow the phenomenology exhibited by thedroplets. By coupling the data from the thermocouple and the image analysis, the thermal evolution and thephenomenologies suffered by the slurry were analysed in detail. In the full paper, the fundamental combustioncharacteristics of the bioslurry will be discussed. These data are fundamental for development of innovativeformulations that can optimize the use of bioslurry in energy conversion systems.

Can the High Correlation Between Yield, Stem Height and Stem Diameter in Giant Reed (Arundo Donax L.)Have a Practical Use?


We assessed the correlation between dry matter yield, average stem height, average stem diameter, and stemdensity on a field experiment with diverse N supply, determining substantial yield differences, in the years 2017 and2018. Yields were determined on plots of about 20 m2 area, whereas biometric variables were measured on sampleareas of 1.5 m2. The field experiment was conducted in the Low Po Valley Plain, Northern Italy, where giant reedgrowth is hardly limited by water availability and responds generously to nitrogen (N) fertilization.To our knowledgethe correlation between yield and the biometric variables stem height, stem diameter and stem density has not beenthoroughly investigated so far. Nevertheless, it is widely held that stem density is generally well correlated with yieldfor most of the crops.Our data revealed high correlation between yield and stem height in giant reed, as well asbetween yield and stem diameter. Unexpectedly, the stem density tended to be negatively correlated with yield.

Effect of Irrigation Reduction on Arundo Donax Biomass in a Pot Experiment


Arundo donax (Giant reed) is an energy crop with higher water requirements, but can survive in rainfed conditions.Recent works have been developed to evaluate its drought tolerance although crop irrigation increases biomassyield of Arundo donax. The aim of this work is to compare the effect of irrigation reduction in Arundo donax biomass production in soils withdifferent characteristics.Two soil with different properties (field capacity, pH, organic matter and nutrients) wereused. Plants were established in 10 liter pots in an umbraculum. Irrigation dose was adjusted according to soil fieldcapacity and environmental conditions. Two irrigation doses per soil were assayed 100% of field capacity and 75%of field capacity. Biomass was evaluated after one and two growing periods Irrigation reduction lead to a drastic reduction of biomass production of Arundo donax that was more acute after twogrowing periods of reduced water supply.

Economic and Environmental Advantages of Miscanthus Cultivation on Marginal Lands - Lesson learnedfrom the MISCOMAR Project


The objective of MISCOMAR project was to determine the technical potential of novel Miscanthus hybrids to deliverbiomass production options on marginal and contaminated land, and to determine and quantify changes in soilhealth and structure under these crops. We confirmed the suitability of Miscanthus for production on marginal and heavy metal contaminated land. Novel,seed-based hybrids produced high biomass yields on marginal soils and demonstrated phytostabilisation potential onland contaminated with heavy metals. Metal contamination in harvested biomass was low and did not affectanaerobic digestion or combustion quality.

Effects of Nitrogen Nutrition on Biomass Production of Typha Domingensis to Bioethanol Production


Typha domingensis Pers. is a perennial monocotyledon herb that is usually found in wetlands and marshlands. T.domingensis has a great capacity to remove nutrients from water, especially nitrogen, and hence it has been used inwastewater treatment plants. Also, it can be highlighted the production of easily fermentable starchy rhizomes andthe life form (helophyte), a perennial with annual growth cycle. Several studies have demonstrated the potential ofcattail rhizomes for bioethanol production; however, there are few studies of Typha´s requirements to enhance theproduction of rhizomes and the effect of nutrients on cattail growth.

Legume Intercropping with the Bioenergy Crop Sida Hermaphrodita on Marginal Soil


The cultivation of perennial biomass plants on marginal soils can serve as a sustainable alternative to conventionalbiomass production via annual cultures on fertile soils. Sida hermaphrodita (hereafter referred to as Sida) is apromising species to be cultivated in an extensive cropping system on marginal soils in combination with organicfertilization using biogas digestates.In order to enrich this cropping system with nitrogen (N) and to increase overall soil fertility of the production system,we tested the potential of intercropping with leguminous species in a 3-year outdoor mesocosm study. Resultsindicate that intercropping in all intercropping treatments increased the total biomass yield, however, grass speciescompeted with Sida for N more strongly than legumes. Legumes enriched the cropping system with fixedatmospheric nitrogen (N2) and legume facilitation effects varied between the legume species. T. pratense increasedthe biomass yield of Sida and increased the total biomass yield per mesocosm by 300%. Further, the total aboveground biomass of Sida and T. pratense contained seven times more N compared to the mono-cropped Sida.

Understanding the Potential of Kenaf in Heavy Metals Contaminated Soils


The increasing demand for biomass for the production of bioenergy is generating land-use conflicts which might beavoided through the establishment of dedicated energy crops on marginal land, e.g. heavy-metal contaminated land.Yet, heavy metals contaminated soils might cause marginality of soils through the degradation of their quality,inducing the reduction of crop yields and the quality of agricultural products, desertification, and the loss ofecosystem services. Therefore, assessment of bioenergy from marginal land should take into account constrainingfactors, such as productivity and biomass quality.

Performance of Three Cultivars of Kenaf (Hibiscus Cannabinus L.) In Zinc and Chromium ContaminatedSoils


The use of biomass for energy has been the subject of many studies on environmental protection, as well as studiesof sustainable alternatives to respond to energy needs in several areas of activity. In the environmental context, thesoil, being a resource of vital importance for the development of the species, when exposed to different types ofcontamination, can cause agricultural productivity loss. Soils contaminated with heavy metals can contributesignificantly to desertification, loss of ecosystem services, and high levels of heavy metals in the soil aredeterminants of growth, biomass production, biomass quality and crop productivity.Production of Kenaf in soils contaminated with heavy metals has been the subject of discussion in several forums,since this crop shows some suitability for phytoremediation, and the biomass being produced can still present someeconomically aggregated value. In fact, kenaf is a fiber crop with potential to be used as a feedstock for bioenergyand biomaterials.

Production of Oil Crops Under Heavy Metals Contaminated Soils


Soils contaminated with heavy metals might show signals of marginality through the degradation of their quality,inducing the reduction of crop yields and the quality of agricultural products. Cultivation of energy crops in heavymetals contaminated soils is an option once it contributes to reduce land use competition with food crops andadditionally, to the remediation of heavy metals contaminated soils. The work presented aims to study the effects ofdifferent heavy metals on growth, yield and biomass quality of different oil crops: Camelina sativa, both Winter andSpring varieties; Brassica carinata; Thlaspi arvense. The soils were artificially contaminated - Zn: 450 mg/kg; Pb:450 mg/kg; Cd: 4 mg/kg and Ni: 110 mg/kg, and the crops were also sowed in soils without contamination as control.Sowing was done in the beginning of November and along the growing cycle (until the end of May) the crops will befollowed in terms of height of the stems and the number of leaves. In order to better understand the responses of thecrops to the contamination, the mechanisms of the antioxidant responses of leaves will be also investigated.

Effect of Treated Sewage Sludge on Dry Weight Biomass Production in Ten Different Energy Crops.


Biomass production of energy purposes is a friendly alternative to petrol all over the world. In this terms, shortrotation crops (SRC) are emerging as one of the most efficient alternatives due to their short-term benefits. The use of sewage sludge as an organic amendment to improve soil productivity is a very attractive option, since inaddition to increasing soil fertility. It has a low cost and is a convenient alternative for the management of this type ofwaste, whose handling or disposal is often difficult and expensive.The objective of the study was to evaluate the effect on dry weight biomass production of two types of treatedsewage sludge, composted with pruning wastes (CP) and thermally dried (ST), and compare them with theproduction without application of any organic amendment (control).The assay tests ten taxa of woody species forenergy purposes. The application of thermally dried sludge (TD) increased representatively the production in dry weight in eight of tentaxa. Only one taxon presented higher production for composted sludge (CP), as well as a single taxon showedhigher yields in the control plot.

An Alternative Cropping System Suitable for Biomass Production and Remove Cadmium fromCadmium-Polluted Paddy Field


[Aim and approach used] Developing bioenergy plants in heavy metal polluted soil can not only avoid occupyingarable land for staple food crops by energy plants, but also be able to absorb, remove heavy metal and remediatepolluted soil. Rice is an important staple food for people especially in East or Southeast Asia. However, it is a majorsource of Cadmium (Cd) intake for human in Southeast China, since the paddy field was polluted by Cd. Italianryegrass (Lolium multiflorum Lam) is one of potential bioenergy plants since it has the characteristics in highbiomass productivity and high biofuel conversion efficiency. The alternative cropping systems, Italian ryegrass(energy grass) – Rice (staple food crop) rotation system with and/or without clipping, rice unitary cropping system inwinter fallow field were set up. [Scientific innovation] Cultivating energy grass - Italian ryegrass instead of winter fallow field before rice cultivationcan not only promote biomass production by using low/moderate Cd-polluted paddy field, but also phytoremediateCd-polluted paddy field. [Main results] In compare with winter fallow field, the total amount of biomass in Italia

Innovative Lignocellulosic Crop Rotation Systems as a Source of Feedstock for Biofuels Production


Crop intensification technologies have the potential to supply diversified indigenous lignocellulosic feedstocks, whilestrengthening links between food and energy security. In this study dedicated lignocellulosic crops with long termviability and economic feasibility (sunn hemp, fiber sorghum, kenaf, and hemp) are being tested to be incorporatedinto traditional crop rotations in order to increase the annual biomass yield per unit land. Preliminary results from Italyindicate that fiber sorghum and kenaf produced the highest and lowest yields, respectively, suggesting thatdepending on the species and growing conditions innovative lignocellulosic crop intensification systems couldsignificantly increase the availability of feedstocks locally for biofuels production, thus reducing the feedstock supplydistricts without land competition issues.

Bioenergy in Romania. A Short Overview of Biomass- And Biogas-Based Plants


A number of biomass- and biogas-based plants, currently operating in Romania, are presented and described in thispaper. Based on the available information, their operating conditions and capacities, the feedstock and conversiontechnology used as well as the techno-socio-economic barriers met by the operators/investors are listed andsummarized. As the study shows, majority of the plants operate in the co-generation mode, i.e., produce electricityand heat. Electricity is generally delivered to the national grid, receiving green certificates, while heat is used by theplant operator in various heat demanding processes as well as for district heating. Biomass-based plants are mainlyoperated by wood processing companies that generate large amounts of wood waste. Biogas-based plants arelocated and operated by companies in the agri-food sector.

The polycyclic plantations (PP) are innovative crops that allow to growth in the same crop woody species for veneer,plywood, sawn and biomass production. The possibility of producing, in addition to noble hardwood, also wood forplywood industry (mainly with poplar) and biomass for energy (or industry) purposes, represents a strong innovationthat makes these plantations more profitable both from the economic and environmental point of view with respect topure ones. Fast growing species as poplar showed very good yields in the first trials, opening the way for moresustainable forestry productions.

N Fertilisation Strategies for the Use of P-Rich Organic Amendments in Restoration of Soil Productivity.


The first priority for use of biomass is food and other high value products. The last option of biomass use in thecascade chain, from production to the different uses, may be as soil amendments and fertilizers. Solid fractions ofwet/dry separated manure are usually are rich in P, with a low NP ratio. We examined how the amount and the NPratio of composted dry fractions of anaerobically digested pig manure affected the productivity a legume (Red CloverLea) and a grass (Westerwold ryegrass, Bartigra) species in a pot experiment with two sandy nutrient poor soils. For both soils and species, three doses of the amendment were added to give soil P-AL values of 2, 4 or 6 mg/100gsoil, respectively. Doses of organic amendment were combined with ammonium nitrate to obtain treatments with NPratios of 4, 8 and 16 in addition to a treatment with no ammonium nitrate (NP ratio 1.8). The soils were inoculatedwith red clover rhizosphere soil. The red clover plants were harvested once at beginning flowering, while Westerwoldryegrass was harvested 4 times at shooting. In a third set of treatments, the soils of the red clover plants were frozenafter their harvest, thawed and repl

Production of Alkenes by Catalytic Cracking of Algal Biomass


The light alkenes ethene (C2), propene (C3), and butene (C4) are produced at refineries mostly by steam crackingand fluidized catalytic cracking of petroleum fractions, such as naphtha and ethane. Solid acid catalysts, such as thealuminosilicate Si/Al and zeolite, are commonly employed for cracking, as their surface acid sites are effective atcleaving C-C bonds. In recent years, various biomass feedstocks, primarily cellulosic ones like wood, sugarcanebagasse, rice husk, and saw dust, have been studied as renewable sources of light alkenes using catalysts similar tothose employed by the petrochemical industry. We explored catalytic conversion of microalgae to alkenes becausealgae are a promising sustainable feedstock thanks to a number of attributes, including fast growth rate (just days),elimination of food versus fuel competition, availability year-round, and ability to grow on low-grade resources, suchas waste water and flue gas CO2 from industrial emissions. We focused on production of light alkenes from wholemicroalgae cells, not from extracted algal lipids, in order to avoid the energy-intensive and costly lipid isolation step.

A Novel Dye-Based Light Manipulation Strategy to Increase Photosynthetic Active Radiation for theEnhancement of Microalgal Metabolites


Microalgae have attracted considerable interest due to their extensive application in the various industries. However,to achieve commercial feasibility efficient mass cultivation strategies with high metabolite productivity needs to beinvestigated. Light is a crucial factor that governs growth and biochemical composition of photoautotrophicorganisms. Microalgae only utilize a small fraction of solar radiation for photosynthesis. By improving/maximizing thelight utilization efficiency, microalgal biomass and/or metabolites production may be enhanced. In this study, weemployed organic dyes as light converters and concentrators and examined their effects on the growth, physiology,and metabolite production of Chlamydomonas reinhardtii. Organic dye emissions increased metabolite content butdid not increase biomass concentrations. Quantum efficiencies increased consistently implying light absorbed by thealgal photosystem 2 was being channelled toward photochemistry and photo-acclimation. The results confirmed thatphotosynthetic performance under acclimation can be associated with the augmentation of pigments toward lightcapture rather than dissipation. The study confirmed that the organic dyes converted some unused wavelengths touseable ones, thereby increasing the productivity of metabolites in microalgae.

Strategies for integrating biomass into energy systems, 5CO.2 ROOM 5A


Towards the Implementation of Small District Heating Grids in South-Eastern Europe


The objective of the CoolHeating project, funded by the EU’s Horizon2020 programme, is to support theimplementation of "small modular renewable heating and cooling grids" for communities in South-Eastern Europe.This is achieved through knowledge transfer and mutual activities of partners in countries where renewable districtheating and cooling examples exist (Austria, Denmark, Germany) and in countries which have less development(Croatia, Slovenia, Macedonia, Serbia, Bosnia-Herzegovina). Core activities, besides techno-economicalassessments, include measures to stimulate the interest of communities and citizens to set-up renewable districtheating systems as well as the capacity building about financing and business models. The outcome is the initiationof new small renewable district heating and cooling grids in 5 target communities up to the investment stage. Theselighthouse projects will have a long-term impact on the development of "small modular renewable heating andcooling grids" at the national levels in the target countries.

Model Based Simulation of a Steam Storage System for Flexible Biomass Combustion Plants


The extensive installation of renewable energy systems in the last few years — especially wind and photovoltaicpower — has caused various difficulties due to the rising share of variable, non dispatchable energy generation. Toensure grid stability in future, energy storage devices and dispatchable power plants are required.In this context, the Institute of new Energy Systems at Technische Hochschule Ingolstadt is working on a researchproject to enable flexible power generation of solid biomass fuelled plants. Within the research work, concepts aredeveloped to integrate high temperature storage (HTS) devices into the steam cycles of biomass combustion plants.The idea of storing and re-injecting steam to the steam cycle via storage systems allows flexible power generationaccording to the grid and market demand.A novel combination of the established steam accumulator and a solid thermal store is selected as the most suit-ingsystem concept. To investigate the performance and the system subservience of this approach, a Matlab/Simulinkmodel is developed.

Fundamental Aspects Of Pyrolysis, 3CO.3 ROOM 5B


Can the Oil Yield of Catalytic Pyrolysis of Biomass Exceed the One of Thermal Pyrolysis?


In the context of biofuels, the reported oil yields in catalytic pyrolysis are low ( 26 %), and the deoxygenation levelsare limited (15-20 % of final oxygen content). In this account, the aim of this study is trying to identify the phenomenaleading to these low oil yields in catalytic pyrolysis. To do so, thermal and catalytic pyrolysis of pine and cellulosicmaterials has been studied by following the yield and characteristics of two families of organic compounds in theproduced liquid, oil-phase organics (OPO) and aqueous-phase organics (APO). OPO represents the desired productfor energy purposes. To cover a wide range of operating conditions, we have analyzed the performance of twocatalysts with different acidity (ZSM5 zeolite and Na2O/g-Al2O3), two process configurations (in-situ vs. ex-situ) anddifferent catalyst-to-biomass ratios. Interestingly, under all the conditions studied the OPO yield never exceeded theyield obtained in thermal pyrolysis.

Secondary Char Formation During Slow Pyrolysis of Biomass


This study looks at the phenomenon of secondary char formation during the slow pyrolysis of biomass. While it iscommonly believed that the vapor phase may contribute to the solid yield under certain conditions, the contributionmay be insignificant and the specific conditions not well defined. The conducted literature review and experimentaltrials aim to contribute to this lack of knowledge.

Woody and Agricultural Biomass Torrefaction: a New Approach to Model Solid Conversion and VolatileSpecies Formation Based on Biomass Extracted Macromolecular Components


Biomass waste is an uderexploided and highly diverse ressource, including woody, herbaceous and agriculturalproducts. The European Project Mobile Flip proposes to develop mobile conversion units to valorize this biomasswaste at local scale. One of the proposed technologies is torrefaction (200-300°C, inert atmosphere). It produces asolid with properties closer to those of coal, suitable for energetic purposes, and releases volatile species that canhave an interesting added value as green chemicals.The objective of this study is to develop a torrefaction model able to predict both solid and volatile species yieldsversus operating conditions and biomass type thanks to experimental data obtained on extracted macromolecularcomponents from four biomass families on a TGA-GC/MS. An additive approach of the behavior of the extractedmacromolecular components in torrefaction was proposed to represent the global behavior of biomass intorrefaction. The obtained model was succesfully validated with 14 biomasses representative of the Europeandiversity.

Co-Pyrolysis of Mexican Biomasses with Lldpe Using Modified Clinoptilolite as Catalyst


Three different Mexican biomasses originary from Veracruz state (persian lemon peel, bitter orange peel andcoconut shell) were physically mixed with a common polymer (linear low-density polyethylene, LLDPE) and appliedfor in-situ catalytic co-pyrolysis by using an acidified clinoptilolite as catalyst. The presence of polymer decreased inall cases the bio-oil and gas yields, while increasing biochar yields. On the other hand, the presence of catalystincreased the gas yields for lemon peels, while increasing bio-oil yields for orange peels and coconut shells. Thequality of biogas was enhanced when both polyethylene and clinoptilolite were present in the mixtures, by increasingH2, CO and CH4 production. Some tests such as GC-MS, calorimetry and elemental analysis (for bio-oils), andTGA/DSC coupled to MS are still pending, while also thermogravimetric kinetic modelling is contemplated for thebetter understanding of this catalytic co-pyrolysis process.

European strategies for Biomass Utilisation, 4CO.4 ROOM 5C


Three Switch Points on the Road to a Long Term Sustainable Bioenergy Strategy


Bioenergy is a limited resource. To reach the 2° target from Paris agreement, bioenergy provision has to serveenergy and climate policy most efficient. As bioenergy systems are already established, transformation strategies willbe necessary. There are many aspects to consider when deciding about those strategies politically. Technologyreadiness, energy system integration, economic effects, environmental risks, acceptance and GHG-abatementpotentials but few of the important factors are to consider.

The Regional Carbon Neutrality Achievement by Reducing Emissions and Developing Sustainable ForestUse in Finland


The aim of the study is to promote ways to reach the goals of the carbon neutrality at theSouth Savo region in eastern Finland by examining the solutions for emission reductionsand forest use. The study has taken the first step for reaching the cost-effective carbonneutrality at the regional level in Finland. The carbon dioxide neutral region means thatthe region’s internal activity does not change the carbon content of the atmosphere. Thecarbon neutral society produces just as much carbon emissions as it can bind from theatmosphere.

Waste Framework Directive and Circular Economy Package on EC 2030 Bioenergy Targets: towards aSustainable Bioenergy Policy


Biowaste could represent a sustainable source for energy that can substitute fossil-based sources in the wholebioenergy sector. The expected energy demand from biomass in EU in 2030 is approximately 147 Mtoe by 2030,compared to 124 Mtoe in 2020. This amount has estimated considering the production of 45 to 64 Mtoe from EUagricultural residues, and of about 76-110 Mtoe of forestry biomass. An additional, important bioenergy source couldbe represented by the biowaste. The European Commission defined biowaste as biodegradable garden and parkwaste, food and kitchen waste from households, restaurants, and comparable waste from food processing plants(EC, 2016)1. Unfortunately, biowaste is still at early stage on being integrated in an efficient value chain. The targetof this assessment study is to demonstrate that a specific action plant for a new circular bioenergy policy is needed,that specifically promote the creation of “biowaste-based” end-of-waste materials, to establish effective supplychains targeted to collect and reuse non-contaminated biowaste as bioenergy source, ensuring the recovery of thevaluable renewable elements largely produced during our daily life.

The role of policy in facilitating market implementation, ICV.1 POSTER AREA


Bio-Think Project Fior Second Generation Biofuels


The French start-up BIO-THINK finalized a revolutionary process for using biomass to produce second generationbiofuels. These are liquid biofuels from waste and agricultural by-products in order to avoid the negative effects onfood of first generation biofuels. The process is today unique. It starts from the same fermentation as the production of biogas but the products areliquid and not gaseous fuels. It can be implemented at diverse scales. This process is simple and has better yields than many other biofuels processes. It does not rely on expensivepretreatments of biomass, as it is the case for cellulosic ethanol. BIO-THINK is preparing the implementation of an experimental unit of some kilos of acids of biofuels per day (10 to20 kg/d) costing 0,5 M€. It already looks for financing several million euros and for industrial partnerships to be ableto go to a demonstrator (1 to 1,5 t/d), before selling in 2021 its first small units.

An Experience of Customized Yeast Use in Bioethanol Production


This work followed the dynamics of the yeast population of a bioethanol plant during three seasons using asinoculum a yeast strain isolated from their own process (customized yeast) during the previous season. At the end of the three seasons, SM 854 behaves as the dominant strain, just as in the beginning of the season. Inview of these results, it is possible to assume that yeasts isolated from the process itself can have a promising useas inoculum. Nonetheless, it was possible to notice that yeast population dynamics varies from one season toanother.

Experimental Study on the Grindability Tests By Mixing Ratio with Coal and Biomass


Biomass is used for firing and co-firing in thermal power plant. It has a fibrous structure and has a low grindability ascompared to coal. When the biomass is used in the pulverized coal boiler, it causes problems such as incompletecombustion and increased power consumption of pulverizer. In this study, a method of measuring the grindabilityunder the mixing ratio with coal and biomass is developed and characteristics were analyzed. grindabilitymeasurement development was carried out base on the HGI method. HGI method of coal is measured on massbasis and the case of biomass is used volume basis.

Accurate Determination of Moisture Content in Wood Chips


The energy production in Danish CHP has recent years changed from fossil fuels to biomass such as wood chipsand wood pellets. Especially the share of wood chips has increased in the last years resulting in certain challengesas these contains a highly variable amount of water compared to most other fuels. The present experience withcommercially available online measurement systems is that it is not possible to perform a representative calibrationfor wood-chip measurements due to the inhomogeneity of the fuel. This entails that the measurements are unreliableand cannot be used as control parameter nor for quality control of the wood chips. The inhomogeneity of the woodchips requires numerous samples for analysis, which is cost-intensive. The goals of the ongoing Danish funded research project Real Moisture Content are to achieve a significantimprovement of the uncertainty of the determination of the water content in wood chips with new equipment onlinemeasurement equipment and to validate the basis of the reference method. A method for improving the quality of themeasurement of the water content in wood chips used for biomass boilers for district heating is thus

The Alternative and Renewable Transport Fuel Industrial Forum: Main Results of Two Years’ Work on EuPolicies and Markets


The Alternative and Renewable Transport Fuel forum (AFF) was initiated under the project: “Support for alternativeand renewable liquid and gaseous fuels forum (policy and market issues)”, a tender issued by the EuropeanCommission – DG Energy. AFF aims at bringing together selected representatives of the European Alternative andRenewable Transport Fuels (ART Fuels) production industry, the transport consumption industry, the maininternational cooperation actors and the EU policy makers and stakeholders. During the period following the EC proposal for REDII (end of 2016), the forum developed and communicated thepositions of the various teams through its website www.artfuelsforum.eu and other media. Following the elaborationof an AFF internal survey on market and policy development in the EU, the AFF analysis was carried out at bothGeneral and Sector-Specific levels, and translated into dedicated position documents. The main outcome of thiswork was therefore a set of recommendations to EU Commission, Parliament and Council, with industrial priorities toachieve the EU targets. Among others, the forum called for a more ambitious vision, possibly beyond the 2030.

BioReg Project: How to Fully Unlock the Unused Wood Waste Potential in Europe?


Absorbing the potential of wood waste in EU regions and industrial biobased ecosystems is the objective of theBioReg project funded by the European Union. For the purpose, five model regions were analyzed and threerecipient regions were engaged in replication of good practices. Therefore, the current work aims to identify ‘successfactors’, i.e. factors that have contributed to the development of successful wood waste ecosystems in the modelregions as well as factors that seem unsuccessful in this respect and to provide lessons and recommendations forregional authorities, policy makers and industry stakeholders in recipient regions. Lessons and recommendationshave been identified: a) Structuring the offer of wood waste products by means of a robust classification system; b)Increment of the exploitable deposit by enhancing collection and reducing landfill; c) Sorting development of differentclasses of wood waste; d) Careful sorting and handling to ensure the compliance with the quality requirements of thedifferent end uses; e) Promotion of the development of material recovery in panels; f) Development and optimizationof the energy recovery from the wood waste.

Biomass gasification, gas cleaning and utilisation for heat and power generation, 2CV.2 POSTER AREA


Enhancing Gasifier Hot Gas Filter Performance Through Innovative Ceramic Filter RegenerationTechniques


In this study, the problem of gasifier hot gas filter durability and performance is addressed. More specifically, aninnovative ceramic filter regeneration or cleaning through soot gasification is attempted. Current filter cleaningmethods include oxidative regeneration (leads to extensive material failure due to high temperature gradients) andreverse air/nitrogen pulses (interrupts process and induces additional solid waste handling costs). In this study, filterregeneration under reducing conditions is attempted with the use of steam and CO2 as carbon consumption mediain order to avoid high temperature peaks and increase biomass conversion efficiency as well as H2 and CO yields.The kinetic parameters of the proposed process are investigated through basic research and kinetic modeldevelopment. The results of the study are a key step towards the successful investigation of hot ceramic filterimplementation in small scale biomass gasifiers as a simultaneous filtering and tar catalysis component.

Environmentally Sustainable Fluidizable Catalyst for the Conversion of Tars from Biomass Gasification


Thermal biomass gasification is a promising chemical process. Gasification can efficiently convert low value solidbiomass into synthesis gas. In particular, biomass steam gasification in fluidized beds involves: (i) rapid biomassheating, (ii) effective heat and mass transfer between solid and gas phases, (iii) fast gasification at close touniform bed temperatures. Moreover, biomass gasification in fluidized beds allows the processing of a wide range offeedstocks with broad particle-size distributions. However, in order to produce a high quality syngas/or hydrogenfrom biomass gasification, it is necessary to address the technical challenges resulting from the undesirable tarformation. Regarding ash, different literature contributions describe ash activity in biomass gasification The ashinfluence on gasification has been attributed to alkali and alkaline earth ash components. Therefore, one canenvision a successful biomass gasification process that takes advantage of ash components, minimizing costlydownstream tar disposal and increasing the biomass conversion to valuable products.

Biomass-Based Systems for Atmospheric Water Generation, A 1.75 M$ Idea. Account of The X-Prize Award


The challenge was creating water from thin air to win $1.75 million Water Abundance XPRIZE. The XPrize is anonprofit organization that designs and manages public competitions intended to encourage technologicaldevelopment that could benefit humanity within the general mission to bring about "radical breakthroughs for thebenefit of humanity" through incentivized competition.The constraints were so tight that out of 100 teams from 30 countries that started in the contest, there are now only 2finalists. SkySourceAlliance team developed an unique integration of an atmospheric humidity harvesting processwith a biomass gasification. On October the 20th 2018 SkySourceAlliance won the prize. The core of the winningidea was the use of wood biomass to greatly expands the water vapor available for the atmospheric water generator(AWG) to harvest. The proposed solution had also the higher advantage to be weather-independant. This kind ofdependency has previously limited the relevance of AWG machines to environments with high relative humidity i.e.the tropics. The dependency was overcome through a smart integration between biomass gasification and standardAWGvapor compression cycle.

Enhancement of the Load Modulation Capability of a Pilot Plant Gasifier by Means of Secondary Air Control


The focus of this study is on the operation of small-scale biomass gasification systems for heat and powerproduction (CHP). Small-scale CHP biomass gasification units typically lack the capability for load modulation, whichrefers to the adjustment of energy production to meet the energy demand. Producing energy when it is needed (loadmodulation), is an aspect that should be considered in order to enhance the effectiveness of the plants. The aim ofthis study was the assessment of the load modulation capability of a pilot plant CHP system that is set up at theBiofuels and Bioenergy lab at the Free University of Bozen - Bolzano. The novelty of this research is the investigationof the effect at different loads of the ratio between primary and secondary air, with the aim to improve the loadmodulation capabilities by means of controlling the air distribution and achieving the higher possible conversionefficiency with varying amounts of producer gas power production. The results confirm that it is achievable to have high gas conversion at varying loads using the mass flow rate ofsecondary air as a control parameter for the management of the equivalence ratio into the reactor.

From Equilibrium to Kinetic Modelling: The Gasification of Apple Pruning Residues in a Spouted BedReactor


We have considered residues from the pruning of apple trees, an abundant agricultural waste. In previous works, weobtained their kinetic parameters through thermogravimetric analyses. Moreover, we succesfully gasified them in aspouted bed pilot plant. In this work, we simulated the gasification experiments taking into account the studiedreaction kinetics. We show that this kind of kinetic modelling allows obtaining more accurate results than theequilibrium approach. The plant was modelled through the commercial program Aspen Plus 10.

Predicting Producer Gas Composition in Bubbling Fluidized Beds Using Chemical Equilibrium andEmpirical Correlations


In this work, two approaches to predict the producer gas composition obtained by direct (air) biomass gasification inbubbling fluidized beds (BFB) were developed, compared and evaluated, namely nonstoichiometric thermodynamicequilibrium modelling and empirical modelling based on reported experimental results in the literature. The mainobjective is to identify deviations between thermodynamic equilibrium predictions and empirical correlationsdeveloped based on practical BFB gasifiers results. Several literature data regarding the characteristics of theproducer gas and gasification efficiency parameters is presented. Significant deviations were found between thenonstoichiometric thermodynamic equilibrium model and the developed empirical correlations. Furthermore, it wasfound that both model and empirical correlations need to be improved to increase the accuracy of the prediction ofthe producer gas composition, and consequently be able to serve as reliable tools to support the design, up-scalingand operation of direct (air) gasification plants with BFB reactors.

Assessing the Effect of Gasification Char on the Removal of Model Tar Compounds in a Tar CrackingReactor


Tar formation is one of the main issues in biomass gasification technologies, hindering their development andimplementation on a wide scale. Many studies have investigated the activity of char as catalyst or as catalystsupport for tar removal, but the main research has concerned char obtained from pyrolysis of biomass undercontrolled conditions. The present work investigates the use of char obtained from operating gasification systems asadsorbent and catalyst for the removal of tars using a specifically designed fixed?bed tar cracking reactor.Preliminary tests have been carried out using toluene as model tar compound and further experiments areenvisaged with other operating conditions (temperature and GHSV) and with other compounds (naphthalene andphenols, in particular) that are representatives of the different classes of tar usually found in the producer gas. Tarremoval efficiency of char samples is evaluated based on inlet and outlet concentrations of toluene.

Gasification of Woody Biomass in an Interconnected Fluidized Bed


The gasification of the mixed woody pellet in a 20 kWth interconnected fluidized bed (IFB) was carried out in thestudy. The four fluidization compartment beds connected by weirs and orifices are employed in the IFB system. Thetwo lean-phase beds denote the gasification zone and the combustion zone, respectively. The two dense-phasebeds denote the piping and feature to prevent the gas penetration from one lean-phase bed to another one. Theresults show that the contents of CO and H2 increased with increasing the gasification temperature, but the contentsof CO2 and CnHm show the contrary results. In addition, the contents of CH4, CO, and H2 increased with increasingthe gas velocity, but the content of CO2 shows the contrary result. The content of CnHm decreased when theoperation temperature was set as 700°C, but it increased at 750°C and 800°C, respectively. It is suggested that themetal contents in the rice husk acted as the catalyst on the CnHm production.

Evaluation of the operational behaviour of fixed-bed biomass gasifiers – A novel approach for steady-stateanalysis


The paper / presentation will show a comparison between typically applied standard methods and a newly developedmethod for the evaluation of the operational behaviour of fixed-bed biomass gasifiers at steady-state. Typically,standard methods select as many substance balances or mass balances as number of parameters to be estimatedin order to find one single unique solution. Unfortunately, the quality of such standard methods is strongly affected bymeasurement errors and not all information available is incorporated in the estimation of the unknown parameters.The newly developed method incorporates all information available, thus leads to a more reliable evaluation of thesteady-state operation of fixed-bed biomass gasifiers and is less prone to individual measurement errors thantypically applied standard methods.

Evaluation of Analytical Methods for Assessing Biomass Gasification Producer Gas Quality for Solid OxideFuel Cell (Sofc) Operation


An efficient utilization of solid biomass will play a major role in future renewable energy systems. The objective of theongoing project, Bio-CCHP, is to develop a novel tri-generation concept to produce energy, heat and cold withmaximum efficiency and flexibility. This goal is achieved by coupling of biomass gasification with a Solid Oxide FuelCell (SOFC) stack and a cooling machine. For industrial applicability of the concept, an accurate high temperatureproducer gas cleaning unit for SOFC-operation is essential and will be developed and tested. To evaluate gascleaning concepts suitable methods for gas analysis in low ppm and ppb-range are crucial. Therefore, a specialfocus of the project has been put on the comparison and validation of existing methods and on the investigation ofthe suitability of methods regarding detection limits, reproducibility, accuracy and precision as shown in this paper.The paper will show a comparison of different methods for gas analysis including gas sampling. The outcome aimsto provide a recommendation for the most accurate ones regarding trace constituents in biomass gasification basedproducer gas in low ppm and ppb-range.

An Experimental Study on the Effectiveness of Tar Capture in Biochar from Slow Pyrolysis


Slow pyrolysis is effective for biochar production since the low heating rates leads to a larger yield of biochar whilenot requiring a sophisticated rig. Biochar is the solid product with valuable physical and chemical properties such asa high carbon content, high heating value, and strong resistance to biological/chemical decomposition. When appliedto the combustion in thermal power plant, biochar has low density and it has higher shipping cost than coal. Also, theyield of bio-oil from pyrolysis is about 50% and it is difficult to directly utilization as fuel because of higher moisturecontent. This study investigated the properties of tar (bio-oil) capture in the biochar for improving fuel (biochar)quality.

Air Staging and In-Bed Quenching for Autothermal Generation of Char And Low-Tar Producer Gas


An autothermal fixed bed downdraft reactor which combines the production of solid char and producer gas isinvestigated. Air staging is used to reduce the amount of tar in the producer gas, which has been shown to bepositively influenced by the presence of char. In-bed quenching then leads to the release of a cold producer gas,which is filter from liquid constituents within the solid char bed. This combination of high temperature air staging andcold gas filtering is being explored for the production of both low-tar producer gas and solid char.

Integrating bioenergy production potential and agricultural land use in Angola


In Angola, only 30% of the population has access to electricit. Therefore, an assessment of the biomass resourcespotential for bioenergy in the province of Huíla, in Angola, is being conducted, to help designing effective interventionstrategies for the rural energy sector of this province of Angola. Hence, the aim of this work was to integrate thebioenergy production potential from the main agricultural residues and the current agricultural land use in theprovince of Huíla, in Angola. The most significant agricultural crops in the province are maize, sorghum and millet.The potential sustainable crop residues for bioenergy production was estimated by using the residue to product ratioand to meet the challenges of the sustainable production of bioenergy, with a focus on the environmental criteria, theenvironmental impacts derived from the implementation of the biosystems were studied. In this work, differentscenarios for the exploitation of this biomass were taken into account. For the different scenarios, the environmentalimpacts of the biochains were discussed, namely in terms of greenhouse gas (GHG) emissions and non-renewableenergy use.

Innovative Double Cropping Systems Including Camelina [camelina Sativa (L.) Crantz] A Valuable OilseedCrop for Bio-Based Applications


Cropping system intensification (i.e. double, mixed or relay cropping) is becoming an actual topic when dealing withnon-food crops since it has been identified as a simple and remunerative way to avoid food versus bioenergy debateand consequent indirect land use change (iLUC). Camelina in view of its cycle shortness was able to perfectly fit into double-cropping systems in the Mediterraneanbasin while in northern US, where summer season lasts not more than 100 days, relay cropping systems (i.e. theseeding of one crop into another standing crop) are more often adopted to achieve satisfactory seed yield.

Crop Residue Energy Potentials: Trade-Offs and Challenges


The use of crop residues for bio-energy can play an important role in climate change mitigation without jeopardizingfood security, although it can adversely impact soil fertility, and if complemented with higher organic fertilization, leadto higher nitrate leaching and agricultural emissions. We use a spatially and temporally explicit approach toinvestigate the potential of crop residues in light of wider environmental and socio-economic trade-offs. Using NorthRhine-Westphalia in Germany as a case-study, we combine agro-ecological modelling with calculations ofhierarchical residue potentials and stakeholder interviews to identify opportunities and barriers for residue utilization.Increased residue exploitation is associated with higher technical and market energy potentials, lower logistic costs,and higher emission reduction potentials. However, it leads to a deterioration of soil organic carbon, which can beoffset via improvements in agricultural management. A more stringent humus balance approach leads to anincrease in residue potentials without aggravating soil conditions, while optimized fertilization reduces nitrateleaching and agricultural emissions.

Resource Efficiency and GHG Emissions of Wood Product Cascading & Bioenergy in the European Union


Cascading use of biomass is a recognized strategy contributing to an efficient development of the bioeconomy andfor mitigating climate change. This study aims at assessing the potential of cascading use of woody biomass forreducing GHG (greenhouse gas) emissions and increasing the overall wood flow efficiency in the European Union’sforest and bioeconomy sectors. A life cycle approach was followed to quantify the potential benefits of cascading use of woody biomass. Differentsupply chain stages of production were analyzed: forgone fossil-fuels substitution, optimization at manufacturinglevel and forest regrowth. We started with the current waste wood and paper recycling practices (scenario S1). Thenwe compared this current scenario with two divergent options: a scenario in which all post-consumer wood andpaper waste is fully re-utilized for energy (S0) and a scenario with optimized future product cascading (S2). Overall, the optimal cascading S2 scores considerably better (-14 MtCO2-eq/year, equivalent with 8.3% GHGemission reduction) than the full energy scenario SO (-8 MtCO2eq/year or 4.7% GHG emission reduction), incomparison with current practices in the EU.

The BABET REAL 5 Project - Preparing the Implementation of a Second Generation (2G) BioethanolProduction Plant in Bavaria


In the framework of an investigation that was carried out for the BABET-REAL5 project, it could be shown that inLower Bavaria enough residual feedstock is available for the small-scale (minimum threshold: 30,000 tdm/year)production of second generation bioethanol without having a negative impact on the agricultural lands (i.e. soilcarbon). Further aspects (e.g. availability of operating materials) need to be considered to find the most suitedlocation and ensure sustainable feedstock production for the bioethanol production plant. In the following paper, acomprehensive approach is carried out to show what needs to be taken into account for a decision. The results will be presented on GIS maps together with additional information about price and ecological impact (asavailable). The methodology that was used for this investigation can also be used for the analysis of small-scaleindustrial bioethanol production in other regions.

Greenhouse Gas Abatement Optimal Crop Usage for Biofuels Across Transport Sectors in Germany


A complete decarbonisation of the transport sector relies heavily on power based solutions. However, thedeployment of these alternatives requires some time and some sectors, such as shipping, goods transport andaviation may be slower than personal transport in adapting to renewable modes and fuels, due to fewer availableoptions. Biofuels are another option to reduce the climate impact of transport, which are already being used.However, potential and sustainability constraints set limits for their deployment and thus biofuels may play animportant role as an intermediate decarbonisation solution until other renewable options can take over.In this work, the optimal role of biofuels from energy crops for greenhouse gas (GHG) abatement in the Germantransport sectors is investigated under different progressive long-term scenarios, from a set arable land areacorresponding to current use. The optimal deployment is modelled using a fully deterministic, bottom-up perfectforesight optimization model, with the goal function of maximizing total GHG-abatement.

Pyrolysis For Biochar Production, 3CO.7 ROOM 5B


Pecan Nut Biochar as a Potential Support for the Synthesis of Bimetallic Catalysts and their Activity inFurfural Conversion to 2-Methylfuran


Pyrolytic solids, also called biochars, are a potential support for catalyst synthesis and a more sustainable choice.Furthermore, it provides a mean to obtain a highly valuable material by characterizing and modifiying it in order todevelop desirable properties for catalytic applications instead of using it directly for soil remediation. All biocharswere characterized with FT-IR, where bands associated with the present minerals were identified. Characteristicbiochar signals were attributed to N-H and C-O-O vibrations at 1581 and 1450cm-1. Experimental pH valuesobtained for the different biochars showed a decrease in basicity on these materials when compared with the pH forthe original, unmixed catalysts. This may be favorable for furfural hydrogenation into 2-methylfuran, which has beenreported to require a moderate acidity and relatively strong basicity. SEM micrographs showed a combination ofplane and round morphologies, with different sizes and small agglomerates; for CaCO3 and CaO biochars, cubicmorphologies were also observed, which are related with the original catalysts present in the chars.

Biochar Characterization from Thermal Utilization of Biomass for Catalytic and Adsorption Applications


A softwood biomass (poplar) has be chosen for pyrolysis process in different temperatures. The yield of products(char, liquids, gas) has been examined and energy distribution is calculated. The biochar has been characterised byvarious analysis as follows: ultimate (for elemental composition and heating value calculation), proximate (toevaluate wether it contains some volatiles inside), XRF (to examine the inorganic part of the biochar and see if somemetals have been volatilised), BET (to analyse the internal surface area of the pores and their volume) and SEM (tosee the microscopical structure). Then biochar has been used for two purposes: a)as a catalyst to evaluate itscapacity to reform the tar, b)as a solid adsorbent to evaluate its capacity to adsorb the metals present in the gas.Then all the above-mentioned analysis have been repeated on the used biochar to compare the results. Finallydeactivation time of the biochar is studied to find solution for regeneration for continuous use.

Biomass Thermo-Conversion in Activated Carbons Using Microwave Hybrid Heating: Exploring Their Rolein Environmental Applications


The utilization of natural sources such as biomass has been highlighted as alternative in the preparation of newadded-value products. The recovery and recycling of inexhaustible, biocompatible and eco-friendly resources suchas biomass is a highly important issue currently facing the world. Particularly, by thermochemical conversion ofbiomass materials, it is possible to obtain fuels such as, bio-oil and a carbon-rich solid, which are of high interestfrom economic, scientific and industrial perspectives. The thermo-conversion of biomass in added-value productshas been achieved using conventional heating, however in recent years, microwave has been recognized as apromising alternative which addresses the limitations involved in conventional heating mechanisms. Determining thefundamental microwave dielectric properties and the penetration depth of microwaves in the material over the rangeof process parameters is an important step before designing microwave processing systems. In this regard, we havedeveloped a hybrid heating system using biomass and oxidizing agents to prepare carbon adsorbents with highspecific surface area and micro-mesoporosity

Development of an Integrated and Continuous Slow Pyrolysis and Activation Process for the Production ofActivated Carbon from Waste Biomass


The possibility of integrating a slow pyrolysis process with activation of the char produced is investigated using anauger reactor. Production of activated carbon is usually done in a two-step process, by first carbonising a carbonsource (coal, coconut shell, other biomasses, etc.) and then subjecting the solid product, char, to an activationprocess. With this work, by simultaneously producing and activating the char, the cost of production of activatedcarbon could be decreased, and further positive points are the fact that the process is continuous and that thefeedstock would be a biomass-based waste, wheat straw pellets. Activation will be carried out in two separate ways:chemical activation using KOH, and physical activation with a steam atmosphere. The properties of the solidproducts produced will be compared with the properties from the chars activated with the conventional two-stepprocess, as well as from non-activated char. The properties to focus on are the product’s surface area, pore sizedistribution and presence of chemical functionalities, which are key factors for the application of activated carbon inadsorption.

California RNG Production from Woody Biomass


GTI, in collaboration with Andritz (gasifier technology partner), Haldor Topsoe A/S (HTAS, synthesis gas, or syngascleaning and methanation technology supplier), and Black & Veatch (B&V engineering services and balance ofplant), investigated the potential to convert an existing biomass power station (DTE Energy Stockton) into a facilitythat produces RNG via the gasification of woody biomass. The specific scope and purpose of the project were tocomplete a site-specific engineering study for converting an existing woody biomass power plant to a plant thatproduces pipeline-ready RNG. The current annual feedstock consumption was assumed constant for the repurposedplant. The engineering design focused on a facility of approximately 82 million cubic meters (2900 million cubic feet)of RNG production annually. The design includes a connection to the natural gas pipeline system and the productionof RNG that meets the existing utility requirements for pipeline quality. A lifecycle analysis (LCA) quantifying theenvironmental benefits of the RNG produced is one of the key study results.

Fractionation of Lignocellulosic Biomass, Scale-Up and Downstream Processing Design for the Productionof Bio-Based Chemicals and Building Materia


A promising approach to address these challenges is to further optimize and upscale a mild organosolv process(FABIOLATM) that uses aqueous acetone (50 wt% at 140 oC)1. This fractionation process typically produces C5and C6 sugars in high yields and a potentially less-condensed and reactive lignin fraction with interesting propertiesfor high value product applications . The novelty of the study that will be presented is the simultaneous developmentand upscaling of the organosolv fractionation process combined with the downstream processing of the biomasscomponents at lab- and pilot-scale into high-value chemicals (e.g. malic acid, xylonic acid, acetone, ABE) as well asbuilding materials (PUR/PIR isolation foams, bitumen roofing materials).

Syngas Fermentation at Elevated Pressure - Experimental Results


Gas fermentation using anaerobic bacteria as a biocatalyst is an attractive biotechnological process for thesustainable conversion of synthesis gas. Thermochemical gasification of lignocellulosic biomass or wastes incombination with syngas fermentation offers a sustainable conversion route for the production of green fuels andchemicals. Almost every non-food related dry biomass is suitable for the generation of substrate gas, as well asindustrial off gases. A known bottleneck in syngas fermentation is gas-liquid mass transfer of low soluble gascomponents like H2 and CO. According to Henry’s law, gas solubility can be enhanced by an increase of gaspressure. Therefore, one approach to increase fermentation efficiency is to increase process pressure.

Effect of Medium Composition on Microbial Growth and Bioalcohol Formation in Syngas Fermentation


In this work, effect of the culture medium composition on the fermentation of Clostridium autoethanogenum, which isacetogenic bacteria to product ethanol from synthesis gas, was examined to improve the microbial growth andethanol production. From the results, it can be concluded that the examined medium composition did not improvethe bacterial growth and ethanol productivity simultaneously. Therefore, it is shown that the optimal mediumcomposition of growth and production stage may be different. The results can be applied to improve feasibility of insyngas fermentation.

Metabolic Engineering of Clostridium Sp. Strain WST for Enhanced Production Biobutanol from MarineBiomass


Consolidated bioprocessing is considered as an optimal solution for the direct bioconversion of renewable feedstockinto biofuels. Among the renewable biomass, marine agar biomass had higher concentration of fermentable sugarsviz., galactose which can be efficiently converted into liquid biofuels. Clostridium sp. is well known for its uniquegenomic organization with which it is able to generate biosolvents via ABE fermentation pathway. However, there isno reported Clostridium sp. (native/genetically altered) which contains agar hydrolytic arsenal or has extracellularexpression of recombinant hydrolytic enzymes. Hence, in the present study, a galactose utilizing Clostridium sp.strain WST has been genetically modified for the heterologous expression of extracellular agarases to improve theconversion efficiency of agar polysaccharide to biobutanol.

Improvement of Cellulose Accessibility with Producing Hemicellulose and Lignin Derived Compounds bySequential Pretreatment Processes


Biorefinery, a facility which can produce power fuels, and chemicals from biomass, is called as integrated process.However, biorefinery processes are not competitive because of its inherent recalcitrance. For improving acompetitiveness of biorefinery, it is necessary to efficiently produce glucose from cellulose, which is majorcomponent of biomass. In addition, hemicellulose and lignin are effectively separated in the process with producingvaluable derived products. In this study, liquid hot water treatment and diluted peracetic acid treatment weresequentially performed to improve the cellulose accessibility for enzymatic hydrolysis and to separate hemicelluloseand lignin-derived compounds which can be provided as a raw material for chemical production. To investigate theimprovement of cellulose accessibility, instrumental analysis including surface morphology and BET surface areaand pore characteristic were adopted, and to determine hemicellulos and lignin derived compounds, GC/MS andHPLC were introduced with solvent extraction.

Effect of Magnetic Solid Acid Catalyst for Deconstruction of Lignocellulosic Biomass


Aim of this study was to investigate deconstruction effect of ligocellulosic biomass using magnetic solid acid catalystfor acid hydrolysis and separation. In conventional dilute acid process, inorganic acid such as sulfuric acid orhydrochloric acid were used as acid catalysts. This required additional neutralization for acid catalyst recoveryprocess. On the other hand, solid acid catalyst released less anionic ion and could be separated from raw materials.To accomplish this, silica based solid catalyst was used and modified to improve acidity and separation. Specifically,improvement of acidity was achieved by insertion of sulfonic group and separation of catalyst was accomplished byintroducing magnetic nanoparticle (Fe3O4) in the acid catalyst. Acidic properties of catalyst and deconstructive effectof lignocellulosic biomass was evaluated

Pretreatment and Fractionation of Wheat Straw by Organosolv in Biphasic System


In this work we investigated the pretreatment of wheat straw in a biphasic system constituted by an organic solvent(butanol) and oxalic acid solution. The pretreatments were carried out in a 200 mL Parr reactor. The aqueous phaseand the organic phase contained solubilized hemicellulose and lignin respectively. The insoluble residue hasundergone enzymatic hydrolysis with commercial mix in shaken flasks at 50°C up to 72h. Results have shown thatthe treatment is highly efficient to destructure and fractionate straw since its conversion into glucose by enzymatichydrolysis reached 96% of the theoretical value.

Mango Fruit Waste: an Amazing Biorefinery Opportunity


It is estimated that by the beginning of the XXII century, solid waste generation rates will exceed 11 million tonnesper day setting forth the necessity for sustainable alternatives that supply energy and everyday product demands.Nowadays in Colombia, several companies produce pulp and dehydrated fruits; and their residues are comprisedmostly by peels, husks, and seeds (approximately 6.1 million tonnes per year). One example of this is mangoresidues, that just in 2010 reached about 200.000 tonnes per year, and from this, about 25% to 40% of the rawmaterial is left as residue. For that reason, mango waste is presented as an attractive alternative to designbiorefineries that provide both biocompounds to use in everyday products and biomass to produce bioenergy.Results demonstrate that different routes for a mango fruit waste biorefinery are available and that an energy-drivenbiorefinery would be the best option taking into account that the mango seed without oil and the mango endocarp(husk) could be digested obtaining high methane production rates and values, additionally the oil retrieved could beused in cosmetic products such as moisturizing creams.

Plug-Flow Reactor Based Acid Fermentation for Small-Scale Biorefineries


This project aims to establish a suitable bioreactor module for the flexible conversion of a wide variety of feedstockto produce either short-chain carboxylic acids in an acidic fermentation or methane as alternative. The processfollows a plug-flow principle. Although this technology is not new, its full potential concerning process robustness incomparison to the common stirred tank digester concepts is not used. Intensified monitoring, which takes advantageof the recent developments in digitalization to improve the digestion process, have been applied mostly inround-shaped reactors recently, but rarely in plug-flow reactors. Therefore, the authors propose the consideration ofgradient formation to increase process stability at various feedstock compositions beyond the currentstate-of-the-art. Several probe installations in the liquid phase along the length of lab-scale reactor will ensure aproper monitoring and the development of an expert system.

Converting Coffee Silverskin to Value-Added Products Under a Biorefinery Approach


In this work, bio-oils and biochars from the pyrolysis of coffee silverskin (CSS), a waste from the roasted coffee,have been studied inside biorefinery concept in order to transform the coffee waste into a resource. CSS waspyrolysed at 280 ºC, 400 ºC and 500 ºC and the resulting products (bio-oils and biochars) were studied andcharacterised. The preliminary results show that bio-oils are rich in value-added products as caffeine and phenolicderivatives that would be used in nutraceutical and chemical industry as antioxidants. Moreover, biochar could be apotential energy source for the coffee roasting process. Therefore, this study would allow the valorisation of CSSthrough pyrolysis and so, coming closer towards circular economy and bioeconomy in the coffee industry, convertingits only by-product (CSS) to a resource.

Secondary Tar Cracking in Fixed Bed Using Char Residues from the Wood Gasification


High tar content in the product gas during gasification is one of the major problems which limit the further usage ofthe produced gas. Tar decomposition using char from the pyrolysis of biomass becomes more popular. Alternatively,using the char residue derived from the gasification process shall be also a means for further reducing the tarcontent. In this study, the catalytic effect under different operation conditions of char samples on the tar sample wasinvestigated using a ?xed-bed reactor. The char samples are derived from entrained flow gasification of standardwood pellets and biochar from high pressure carbonization process. Comparison of catalytic tar cracking propertiesbetween different chars is also evaluated. SPA method is used to calculate the tar conversion. TGA and BET arealso used to characterize the chars.

Gasification Ff Microalgae Waste on Supercritical Water Condition


Nowadays, microbial biomass is one of the candidates for renewable energy due to its carbon neutralcharacteristics. We can obtain microalgae biomass sources from freshwater waters in an easy and cheap way but itprovides great energy opportunities in a fast time. One microalgae, Chlorella vulgaris, has a percentage of 20-30 %oil phase. After extraction of the oil, further processing of biomass waste is needed. By utilizing 80% percent of thisbiomass waste as a material that is rich in energy but in a wet state as feedstock, we can produce syngas in areactor willed with supercritical water. This fuel gas can be used to replace the natural gas that is beginning todeplete. We got gas formation as carbon gas and hydrogen which can be produced from the decomposition of C.vulgaris waste at a temperature of 600 oC, 25 MPa. The syngas contains methane gas as well. After we comparedthe results with C. vulgaris without the oil extraction process, the amount of syngas obtained was greater for biomasswaste after extraction.

Biomass Gasification: The Effect of Equivalence Ratio on Syngas Quality in the Case of Externally HeatedReactor


A truly externally heated biomass reactor, such in the case of a gasification plant coupled with a concentrated solarpower system, the equivalence ratio (ER) is not the only parameter affecting the reaction temperature. In theproposed paper we investigate the effect of the variation of the equivalence ratio (ER) in the case of an externallyheated reactor, on both the temperature distribution within the reactor and syngas quality (i.e., composition and lowheating value).This will be done performing ad experimental campaign of waste biomass gasification using an electrically heatedreactor, and varying the ER from 0% (pyrolysis) to 30%.

Analysis of the Gasification Rate of Biomass in a Continuous Particle-Fed Solar-Radiated Gasifier


Solar steam gasification of biomass has been performed in a 1.5 kWth prototype continuous solar gasifier in thetemperature range 1100-1300 °C driven by real high-flux concentrated solar power, provided by a parabolic dishsolar concentrator. An experimental performance assessment of the solar gasifier through a parametric studyconsidering the influence of biomass feedstocks, biomass feeding rate, and operating temperature was conducted tooptimize the syngas production and operation stability of the solar reactor. Various biomass feedstocks werecontinuously fed and steam gasified with different gasification temperatures to produce syngas. Increasing biomassfeeding rate and temperature significantly promoted biomass consumption rate, syngas yield, and syngas quality, inturn enhancing solar reactor performances. However, excessively high biomass feeding rate adversely affected thekinetic rate of gasification reactions with a reduction of the produced H2 and CO at the expense of additional CO2,CH4, and C2Hm due to a decrease in gas residence time. The sensitivity of the syngas yield on the particle size wasalso shown in the considered range (0.3-4 mm).

Biomass and Waste Gasification for the Production of Methanol


The syngas conversion to methanol is an established process with a high technological readiness level. However, itscommercial production via gasification of biomass is obstructed by low fossil fuel and high woody biomass prices. Inthis study several innovative cases towards production of renewable methanol from syngas are compared to areference case where conventional technologies are applied. The results are evaluated in terms of energy efficiency,economic viability and CO2 emission reduction. The base of the analysis is 60 MW thermal input starting frombiomass and waste gasification and the overall efficiency is determined using Aspen modelling and experimentaldata. The incorporation of novel technologies downstream MILENA indirect gasification process - like SorptionEnhanced Reforming of hydrocarbons at low temperature by in-situ CO2 removal and Separation Enhancedmethanol synthesis using a membrane reactor - leads to better efficiency, due to higher product yield and lowerpower and natural gas demand. BTX separation and co-production is beneficial compared to reforming – especiallyfor waste gasification – in terms of overall efficiency and net annual revenues.

Experimental Investigation of Bed Materials Effects on Continuous Solar-Driven Steam Gasification ofBiomass in a Conical Spouted-Bed Cavity Reactor


The use of concentrated solar power technologies (CSP) to drive the endothermal reactions of gasification results insaving biomass resources. Moreover, high gasification temperatures (1200°C) are achieved which favour thereaction kinetics and tars thermal cracking. A novel 1.5 kWth solar conical cavity reactor was earlier designed andtested for allothermal continuous biomass gasification at temperatures up to 1400°C. A CFD (Computational FluidDynamics) model was developed and validated against our experimental data for the allothermal operation of thereactor. The simulations predicted a cavity wall temperature 200°C higher than the inner reaction zone. In fact, mostof the incoming solar radiations are absorbed directly by the reactor cavity while the gases and biomass particlesabsorb a smaller portion of the solar power input. In order, to address these issues different bed inert materials weretested. Their effects on biomass conversion and gas yield were analyzed. The spouted bed particles are expected toabsorb part of the entering solar radiations and to supply heat to the reaction zone by convection, radiation andparticle-to-particle interactions.

Chemical Fractionation of Ash Constituents in Entrained Flow Gasification of Straw


Pressurized entrained-flow gasification of biomass is a sustainable process to produce fuels and chemicals. In thebioliq process straw is pyrolysed and the resulting bioslurry is subsequently gasified into a tar-free, low-methansyngas used for the synthesis of biofuels. At the high temperatures above 1200 °C the ash melts and flows down theinner wall of the gasifier. The slag viscosity has to be in a certain range to form a protective layer at the reactor walland to guarantee a continuous removal. Therefore, the slag composition at the reactor wall has to be well known.Due to several fractionation processes in the gasifier the slag composition at the reactor wall does not corresponddirectly with the slurry ash. Therefore, experiments and thermodynamic calculations were conducted to identifydepletion and enrichment processes in the gasifier. Finally the composition of the slag at the reactor wall is obtainedand can be used for calculation and adjustment of the viscosity.

Catalytic Reforming of Tar Using Biochar as a Catalyst


The presence of tar in the gasification product gas is a key factor limiting the commercialization of many biomassgasification technologies. Catalytic reforming of tar is a promising way to remove tar from the product gas, because itconverts tar into useful gas products (H2, CO). This study investigates the role of O-containing functional groups inbiochar during steam reforming of tar using biochar as a catalyst. A series of steam reforming experiments werecarried out using mallee biochar as a catalyst. The biochar samples were pretreated by steam activation for differenttimes (0-50mins) prior to tar reforming. We studied the performance of various biochar samples in tar elimination aswell as the changes in the physicochemical structures of biochars. It was found that H2O activation increased theconcentration of O-containing functional groups, especially the aromatic C-O structures in biochar, which enhancedthe catalytic destruction of tar.

Truly, it is the natural aromatic structure, which suggests to generate aromatic basic andfine chemicals like guaiacol, phenol and vanillin from lignin. All of these are well-established ingredients in food andflavour industry – yet from petrochemical origin. Starting with a comparison of different lignin depolymerisationmethods (enzymatic, hydrothermal and chemical), highlighting advantages as well as disadvantages of eachapproach, novel achievements towards targeted are discussed. It emerged though, that combining chemicaldepolymerisation with radical starters, such as azobisisobutyronitrile, with hydrothermal conversion with CO2/waterunder elevated pressure and temperature results in a too broad product distribution. On the contrary, Trametesversicolor laccase forms no more than three major products. A combination of chemical/hydrothermal with enzymaticyields a limited product range, which has the prospect to reasonable costs.

Scaling-Up Native Lignin Depolymerisation for Biobased Epoxy Resin Production


The presentation describes research on producing novel epoxy resins from depolymerised native lignin. Lignin in situin wood is depolymerised by a hydrogenolysis process into an oil-like product containing low molecular weightpolyphenols. The biobased chemicals are reacting with epichlorohydrin to produce lignin-derived epoxy prepolymerswhich can be further blended and cured to give polyepoxies with excellent thermal and mechanical properties. Thispresentation describes recent developments of this technology including scaling-up the lignin hydrogenolysisprocess and the impact of reaction conditions on the properties and performance of the epoxy resins.

Specialty Chemicals from Lignins by "One-Pot Multi-Step" Biphasic Depolymerization (Bpd)


In this work, we describe an innovative method for a tailored biphasic depolymerization (BPD) of lignin in immisciblepolar/non-polar solvent mixtures for the production of specialty aromatics and chemical building blocks. The BPDsystems provide an environment for a "one-pot multi-step" valorization scheme combined with a protective extractionand scavenging of reactive intermediates. By fine-tuning the BPD systems’ content and properties, a favorable ratiobetween depolymerization and repolymerization can be obtained, thus tailoring the conversion towards concentratedstreams of specific aromatic products.

Packaging Materials Based on Polyhydroxyalkanoates and Lignin Derived from Grape Pomace


Polyhydroxyalkanoates are biodegradable thermoplastic polymers produced by microorganisms with a largeapplicability. This work suggests the utilization of grape pomace, which is the waste product of the winery industry,as a cheap source of fermentable sugars from grape skins and polyphenolic compounds from grape seeds. It will beshown that various bacteria, producing PHA can grow on sugars derived from grape skins. Next, methods for theisolation of low molecular weight phenolics as well as lignin from grape seeds and bunches will be presented. Thehypothesis that neutral isolated lignins without other impurities (e.g. sulfur) and with a narrow polydispersity can beused as active filler for polyhydroxyalkanoates to prepare foils for packaging purpose has been proofed. Inconclusions, the stabilizing and reinforcing activities of lignins have been proofed. This work was funded through theproject SoMoPro (No. 6SA18032). This project has received funding from the European Union’s Horizon 2020research and innovation programme under the Marie Sk?odowska-Curie, and it is co-financed by the SouthMoravian Region under grant agreement No. 665860.

Socio-Economic Assessment of Alternative Oil Crops Value Chains in Europe in the Cosmos Project: theCase of Camelina And Crambe


The use of Social Life Cycle Assessment (sLCA) and Social Impact Assessment (SIA) for the sustainabilityassessment of value chains has grown over the last few decades. Yet, it has been argued that, independently, theycannot provide a fuller picture of the socio-economic and policy impacts of bioenergy chains, and biorefineries inparticular. This paper discusses a socio-economic assessment of alternative crops for biorefineries in Europe thatuses a combined methodological framework, through a case-study of the COSMOS project (2017-2019). The projectaims to reduce Europe’s oleochemical industry dependence on imported plant oils (sources of fatty-acids andpolymer-building blocks) by turning camelina and crambe into profitable, sustainable, multipurpose, non-transgenicEuropean oil crops. This requires determining the level of acceptability of these alternative feedstocks, the scope formarket diffusion of new technologies, and the social implications.

Hydrothermal Valorisation of Htl Process Water: Salt Separation and Selective Gasification tto SyntheticNatural Gas


In this study, serial hydrothermal salt separation and catalytic gasification to methane were applied to valorisepotassium-catalysed HTL process waters, a waste stream problematic to valorise for the toxicity of its organiccompounds to anaerobic digestion microorganisms.A detailed study has been performed using PSI’s 1 kg.h-1 demonstration rig using process water from pine woodsaw dust. Results showed that the main inorganic constituents, Na and K, could be recovered and concentrated witha respective efficiency of up to 98% and 95%, a brine stream that can potentially be looped back to HTL plant. Inparallel, a steady and selective CH4 production (58 v/v%) was obtained with a high carbon and chemical energyefficiency.Information regarding Ru leaching from Ru/C catalyst along with salt deposition in the up-stream trap was collectedfor the first time and serve as a good base for their optimization.

Continuous Production of Phosphorus from Palm Oil Mill Effluent (Pome) by Supercritical WaterGasification


Increasing production of crude palm oil in Indonesia come along with severe pollution of liquid waste. This wastecalled palm oil mill effluent (POME) is harmful for environtment if no proper handling is carried out. Conventionally,biochemical technologies is employed to utilize POME as source of energy and valuable nutrients. However thismethod requires large treatment area as well as long reaction times. Supercritical water gasification (SCWG) is apotential technology to overcome this problem. Here, SCWG was used to produce inorgnic phosphorus fromorganics contained in raw POME. A continuous reactor was employed in this study and a set of experiments weredeveloped to spotlight the behavior of phosphorus convertion from POME under SCWG. It was found that organiscwas converted into inorganic phosphorus in a liquid phase, in which some precipitation of inorganic phosphorus wasobserved in the reactor. The rate of this convertion increased at higher temperature. The discussions of thisbehavior were developed based on comparison of mathematical model and experimental results.

Seasonal Biofuel Sampling with New Methodology for Optimizing the Combustion Process


A new methodology for sampling of spruce bark and chips biomass has been introduced at a Norwegian sawmill. The methodology provides a more accurate representation of the entire volumes of biomass and provides bettercontrol of the moisture content of raw material. In this study it was important to investigate how many representative samples is necessary to yield a result thatdetermines the feed-in biofuel volumes with required accuracy to have a stable heat production. Due to the vast amount of sampling necessary to achieve accurate and representative results, automated samplingby means of X-ray measurements was added in the campaigns for rapid determination of the moisture content. The project strongly contributes to the green transition overall to ensure that biomass combustion can fulfillegislations and restrictions for emissions and bioash recycling requirements.

Wastewater Virtual Biorefineries- Microalgae, Bioplastics and Fertilizers


The biorefinery concept is usually based on soil crops cultivated worldwide or water cultivated crops such asmicroalgae or macroalgae. However, in a context of circular economy is important to look to urban metabolismwastes, such as urban solid waste or wastewater streams. The municipal wastewater collected in Europe and usingthe 200 L/person/day of the Directive 91/271/EEC of 21 May 1991, amounts to 28.6 billion L/year of potencial waterback to urban households, 1378 ton/year bioplastic for urban products and 636 000 ton/year of fertilizers back toagriculture activities. A reference scenario of tertiary treatment wastewater plant, and three additional scenarios are studied where thetertiary treatment is made by microalgae, to produce animal food (as dry biomass incorporated in the diet ) or toproduce further fertilizers (as dry or wet biomass) and to produce biofilm (for food packaging industry).

Advanced Biorefineries for a Sustainable Waste Diversion


Communities all over are struggling with a huge challenge when it comes to waste management and they are oftendesperate to find new ways to reduce waste sent to landfills and incinerators. While governments are developingpolicies to address the need for more sustainable energy, including low-carbon transportation fuels, global consumergoods manufacturers are also putting pressure on leading chemical manufacturers to replace hydrocarbon-basedproducts with renewable chemical alternatives to meet the demand of their own customers. However, the challengeto reduce waste remains. This presentation will talk about how advanced biorefineries are creating value fromnon-recyclable waste by converting them into biofuels. These facilities are a sustainable alternative to landfilling andincineration and are complementary to recycling and composting.

Cfd Simulation Study of Mass Transfer Performance in a Bubble Column for Applications in SyngasFermentation


Currently sugarcane and corn represent the two sources from which the largest share of ethanol is producedworldwide. However, the availability of those agricultural feedstocks is limited, because of competition with foodproduction, arable land usage, and water availability. An alternative bioconversion method is biomass gasification tosyngas, followed by fermentation to biofuel. This relative new technology is extremely flexible and it has been applied, not only to the conversion of a largevariety of biomasses, but also to the conversion of municipal solid waste and steel mill off-gas to biofuel. However,important aspects need to be addressed in order to improve the overall performances of syngas fermentation. Oneof these is the lack of productivity in the fermentation step ([kg of product]/[m3 of reactor]/[day]).In this study CFD simulation is applied in order to investigate the mass transfer and the hydrodynamic of bubbly flowin a syngas fermenter. A Eulerian-Eulerian multi-fluid approach is used to analyze a bubble column unit, andexperimental data from an industrially relevant reactor will be used for the model validation.

Potential of Gulupa (Purple Passion Fruit) Waste for Biorefineries


In Colombia alone, approximately 12 million tons of food waste is produced annually, most of which accumulatesand overflows in landfills, producing a plethora of undesirable materials and effects. Taken this into account, severalpathways were implemented in which the peels of the passiflora edulis f. edulis (or gulupa, as it is colloquially known)were used to accomplish a variety of objectives. The passiflora edulis f. edulis, a member of the passiflora family(akin to the P. edulis f. flavicarpa, or the passionfruit), is a tropical fruit common to the Colombian cordillera. In thefirst place, a compositional analysis was done in order to thoroughly characterize the content of the peel using NRELprotocols[ and an additional method was used to quantify pectin content. Due to its rich composition, gulupa peelcould be used as a source of pectin, dyes and biomass for biogas production. All of these alternatives were exploredand finally a gulupa-based lipstick was formulated.

Designing an Integrated Thermochemical Biorefinery with a Novel Hydrogen Recycling Concept


TheScope of this work is to design a complete biofuels production chain, ranging from the solid biomass feedstockuntil the production of the high-value bio-intermediate. In other words, we developed flexible AspenPlusTM modellingtools for the three major subsystems: fast pyrolysis, bio-oil hydrotreating as well as the H2 recirculation system (i.e.the electrochemical hydrogen compressor) (more information can be found in the supplementary material). Theflexibility of the proposed model is proved by studying several key operating parameters of each subsystem (FPtemperature, HDT pressure and hydrogen recycling ratio etc.) and the effects thereof on the overall systemperformance. In addition, the performance of the electrochemical hydrogen compressor was investigated byconducting parametric analyses for diverse operating conditions (operating current densities, temperatures etc.). This abstract presents the ongoing work in the BRISK2 project. This project has received funding from the EuropeanUnion’s Horizon 2020’s research and innovation program under grant agreement No 731101.

Efficient Production of Sugars - and Lignin Streams Using Ethanol-Based Organosolv Pretreatments


The development of innovative and low-temperature options based on green solvents for the fractionation ofbiomass is one of the key challenges for biorefineries. This work aims to develop an innovative option aiming at an integrated biomass upgrade concept to improve theproduction of lignin derivatives to value-added applications (biomaterials, aromatics), and clean sugars streams fore.g. fermentation to biofuels and other value-added compounds.Among the most promising options for industrial implementation are the organosolv-based processes since theymay enable an integrated fractionation of biomass and to benefit from a lower CAPEX, specifically if ethanol is thebased solvent, as its recovery can be integrated in the most common biorefinery downstream processing concepts.Nevertheless, this approach still lacks selectivity and efficiency on the recovery and separation of the lignin andhemicellulose fractions.

Exploiting a New Lignocellulosic Biorefinery Model Based on the Use of Non-Conventional Yeasts for C5and C6 Fermentation


In this work two non-conventional wild-type yeasts, a thermotolerant methylotrophic Hansenula polymorpha CBS4732 and a halotolerant Debaryomyces hansenii CBS 767, were used for C5 and C6 fermentation. Hemicellulosicand cellulosic hydrolysates were obtained by hydrothermal pretreatment of wheat straw at 195 °C for 20 min and byenzymatic hydrolysis at 50 °C, respectively. The results revealed a great potential of both non-conventional yeasts tometabolize sugars from lignocellulosic hydrolysates even in the presence of inhibitor compounds to produce ethanoland arabinitol.

Integration of Gasification and Syngas Fermentation to Produce Biochemical Added Value Compounds


The production of bioethanol in second generation biorefineries originates lignin-rich residues that contain lignin,other unconverted fibres, feedstock minerals, and process chemicals. These residues are usually used for heat andpower production. However, other high added value valorisation processes, like gasification, should be studied.Gasification of lignin rich feedstocks differs considerably from gasification of common lignocellulosic biomass, mainlydue to the high ash content, generally with high content of silica and alkali metals, which may bring bedagglomeration, gasifier erosion and serious damage. Thus, it is fundamental to control gasification conditions,namely temperature to prevent ash melting and consequent agglomeration. The integration of gasification withsyngas fermentation is still at an early stage of development and many challenges need to be overcome, includingsyngas quality and suitable composition for the fermentation process. The present works focused on a newapplication, the use of syngas for fermentation to produce biochemical added value compounds.

Production of Biofuels and Bioproducts from Microalgae Using Ionic Liquid Based Processes.


The work deals with the combined production of biofuels and high value products from microalgae under abiorefinery scheme. For that purpose, novel processes based on ionic liquids have been used. These processeswere applied to both model mixtures and real microalgae obtaining promising results in terms of protein andcarbohydrate separation. This indicates the possibility of producing high value products (proteins) and biofuels (viasubsequent fermentative processing of the obtained carbohydrates) by means of the studied processes.

Molasses Cane Sugar Esterilization by Electrom Beam for Ethanol Production


The bacterial contamination present in the ethanol fermentation process negatively affects ethanol efficiency andproductivity. Nowadays, to control bacterial contamination, the Brazilian sucro-energetic ethanol industries performthe acid treatment of yeast, however, such treatment causes damages to the fermentation, as it promotes osmoticstress to the yeast, allows the presence of resistant bacteria and the substitution of selected yeast duringfermentation by wild strains. The sterilization of the must before fermentation is an alternative that can avoid suchlosses and also remove from the ethanol process the acid treatment of the yeast step. For these reasons, thepresent study aims to use the electron beam to sterilize molasses from sugarcane. In conclusion, the dose of 80kGywas sufficient for sterilization of molasses, in addition, the lower doses tested were able to reduce more than 99% ofthe microbial contamination present in the must, evidencing the possibility of applying the electron beam in thetreatment of must for fermentation , which may allow reduction in losses caused by microbial contamination and acidtreatment in ethanol fermentation, besides the

In Site Produced and Commercially Available Alkali-Active Xylanases Compared for Xylan Extraction fromSugarcane Bagasse


xylans can be extracted by xylanase from alkaline-sulfite pretreated material, producing high-purity xylans incomparison with other chemical methods. However, the yield of xylan extraction using xylanase was relatively low,suggesting some limitations for currently available commercial xylanase preparations. For xylan extraction,alkali-active xylanases are particularly desired because high molar mass xylans are significantly more soluble inalkaline medium. On-site production of enzymes is an alternative for several biorefinery designs. This tendency canbe useful to reduce enzyme costs, taking advantage of substrate availability in many biorefineries.

Complete Exploitation of Eucalyptus Nitens: Optimization of Hydrothermal Conversion of its CelluloseFraction to Levulinic Acid and Butyl Levulinate


The fractionation of the structural components of biomass and the valorization of each resulting fraction for specificpurposes enable the development of sustainable processes for biomass utilization, according to the perspective ofan integrated biorefinery. In this work, Eucalyptus nitens ADW (autohydrolysed-delignified sample) wood wasemployed. This cellulose-rich feedstock was used for the production of levulinic acid in water and butyl levulinate inn-butanol, both in diluted acid medium. The effects of the main reaction parameters were optimized. Under the bestreaction conditions, employing microwave irradiation, both target products were obtained with promising yields: inwater (180°C, 20 minutes, HCl), levulinic acid yield accounted for 65 mol%, value higher than those reported in theliterature for similar types of ADW biomasses, whereas, in n-butanol (190°C,15 minutes, H2SO4), butyl levulinateyield up to 30 mol% together with concentration of 54 g/L were reached, starting from an initial biomass loading of 20wt%, values never ascertained in the case of butyl levulinate, opening the way towards its real applications.

Evaluation of Methane Production by Anaerobic Biomass Using Surfactant as a Substrate


The Linear Alkylbenzene Sulphonate (LAS) is one of the most industrially used surfactants and, as a result of itslarge-scale use, it is found in wastewater treatment plants. The anaerobic degradation of LAS has been studied byresearchers in different configurations of reactors and reactional conditions. The aim of this work was to evaluate thespecific methanogenic activity of anaerobic biomass in batch reactors in the presence of LAS, besides quantifyingthe surfactant and organic matter removal as a result of the metabolic activity of the microorganisms. The relevanceof this research lies in the possibility to methane production from the surfactants degradation, once they arerecalcitrant compounds present in domestic wastewater and can cause damage to water bodies, compromisingrivers and aquatic life. The results obtained for the tests, with LAS concentrations of 2 and 5 g/L, confirmed thepossibility of LAS anaerobic degradation since the tests presented specific methanogenic activity of 22.95 and 7.08gDQO/gVS.d and percentage of LAS removal of 73.5% and 70.0%, respectively. In addition, 50.50% removal ofCOD was observed in reactors filled with 5 g/L of LAS.

Mesophilic and Thermophilic Bacteria in Anaerobic Digestion Process


Anaerobic digestion is a complex process where many inhibitor factors in the biomass, such as accumulation ofammonia, volatile fatty acids, and mushrooms, can cause inefficient performances and even process failure. In thiscontest, the substrate temperature and the structure of the microbial community are key parameters to regulate thestability and efficiency of the biogas production process. The temperature is a strategic parameter, which affects theway microorganisms live and act in the biomass. In this contribution, mesophilic (30 – 49 °C) and thermophilic (50 –70 °C) conditions are evaluated in terms of efficiency of the corresponding bacteria community.

Optimization of Feedstock Pre-Treatment for Anaerobic Digestion by In-Line Particle Size DistributionMonitoring with Laserlight Backreflection


Feedstock pre-treatment is evaluated with laserlight backreflection, which enables to monitor the particle sizedistribution in culture broth. Up to now, optimization of pre-treatment, e.g. enzyme addition, ultrasound or milling, isperformed with gas yield measurements, mostly in batch digestion. This takes time and is not easy to perform inparallel. In case of continuous cultivation, a closed mass balance to correctly determine gas yields is not easy toobtain. Therefore, the presented methodology offers a fast alternative method to adjust and optimize feedstockpre-treatment for anaerobic digestion as it is proven that the gas yield depends directly on the particle size in theculture broth.

Temperature Influence On Microbial Diversity And Reactor Performance In Syngas Bio-Upgrading Into RngProcess


Topic Gasification for synthesis gas production•Gas upgrading for SNG applications; Key words: biomethanation; synthesis gas; methane; thermophilic, mixed culture. Renewable natural gas (RNG) plays a key role in the future energy system as a sustainable fuel which is highlyefficient with ultralow emissions. The mandate of the present study is the characterization of a potentially highly efficient and robust biomethanationprocess, capable to go beyond the present biological kinetic limitation. We already reported that the temperature have an effect on the microbial interactions among members of microbialconsortia and determine the predominant metabolic pathways used by the consortia. The changes in the microbialcommunity structure due to higher temperatures lead to higher conversion rates. Consequently, a comparativeassessment of two process operational conditions, mesophilic and thermophilic, is proposed in the present work at alaboratory-scale (40 L). Technology evaluation based on process performance will be set the stage for a life cyclestudy and a future pilot-scale implementation.

Enzymatic Conversion of Mannosylerythritol Lipids in NADES


Natural deep eutectic solvents (NADES) are promising as new media for (bio)catalysis in the food, feed and pharmaindustries. However, their effects on enzymatic systems can be a complex combination of solvation, mass transferand enzyme activity influence, impeding proper interpretation of experimental kinetics. We used supervised machinelearning to create a new solubility model, giving insight in solvation and allowing distinction of various factorsaffecting the kinetics in the upgrading of mannosylerythritol lipids by Novozym-435 as a model system. In a broadersense, this work potentially lowers the impact of production processes, and allows reactions requiring natural mediaonly.

Evolutionary Engineering to Improve Lactic Acid Production From Xylose-Rich HemicellulosicHydrolysates: Obtaining an Acid Ph Tolerant Lactobacillus Pentosus Strain


Having in mind that xylose is the second most abundant sugar in lignocellulose, the use of C5 sugars is an attractiveand challenging approach for the biological production of fuels and chemicals. In this context, the use of C5 sugarsfor lactic acid production has been broadly reported in Lactobacillus pentosus via the phosphoketolase pathway. Thisacid is a rising platform chemical that can be used for the production of pharmaceuticals, chemicals andbiopolymers. The pH drop produced during fermentation due to lactic acid and acetic acid accumulation leads,however, to acid stress conditions affecting the producing microorganisms. In this study, L. pentosus CECT4023Twas developed to improve its acid pH tolerance in xylose fermentation using an evolutionary approach. After asequential batch cultivation with increasing xylose concentrations, a new strain was obtained (named MAX2)presenting even 2-fold more xylose consumption and lactic acid production than the parental strain at different initialpH values. This new strain could be applied in industry, reducing the concentration of neutralizers and maximizingthe lactic acid production from hemicellulosic substrates.

High Yield of Succinic Acid Production from Rice Straw by Metabolically Engineered Escherichia coli


Succinate has become a commercial interest because it can be used for the manufacture of commodity andspecialty chemicals for further syntheses of various high value-added chemicals. Succinate has been classified bythe US Department of Energy (DOE) as one of the top value-added chemicals that can be produced from biomass.Thailand produces rice straw as the agricultural waste approximately 38 million tons a year. Sugars locked in the ricestraw can be converted to valuable fermentation products including succinate. Our objectives were to optimize thepre-treatment process of rice straw by NaOH, followed by an enzymatic saccharification of the NaOH pre-treated ricestraw to maximize the level of fermentable sugars. Succinate production from the pre-treated rice straw bymetabolically engineered Escherichia coli was also demonstrated. Based on our results, succinate concentration andyield from rice straw are highest among those produced from other lignocelluloses reported to date. The results haveevidenced the feasibility of sequential fermentation of pre-treated rice straw with NaOH through SSF as a promisingprocess for succinate production.

In the past decades, as alternative to the petroleum based products, biopolymers, such as chitosan, have undergoneextensive investigation in order to minimize waste disposal problem. Moreover, biopolymers, and their applications,have shown an exponential growth in the past decades as a response to the consumer demand for moreenvironmentally friendly products. Currently, supplementation of the biopolymers by incorporation of antioxidant orantimicrobial compounds is being considered a strategy to improve the bioactivity of those biomaterials. Numerousplant phytochemicals (such as phenolic acids, flavonoids, terpenes, carotenoids, volatile oils, among others), widelydispersed in plants, can participate in protection against the harmful effects of Reactive Oxygen Species and exhibita wide range of biological effects. Therefore, these compounds have remarkable potential to be directly incorporatedas additives into polymeric matrices to serve as active systems. Therefore, the aim of this work was to developbiocomposites based on chitosan incorporated with rosemary or ginger essential oils extracted from the residues ofthose plants and to evaluate its bioactivity.

From Bioenergy to Bioeconomy. Same Sustainability Assessment in The North and Global South?


Bioeconomy not only looks at a more innovative and low-emissions economy but it also may contribute to reconcilethe integration of natural resources such as land for food security and biomass for other industrial purposes . It isexpected that in the next years, the transition from the current fossil-based to a future bio-based carbon economywill evolve creating an impact in all process industries. Ensuring a sustainable production of biomass and its processwill also contribute to socio-economic benefits that extend beyond the generation of jobs including ruraldevelopment, working conditions, income among others.This paper aims to present the proposed framework onsustainability assessment and some metrics used for bioeconomy mainly in the Global South as a response on thetrading and requirements in the North.

Identification and Certification of Low Indirect Land Use Impact Biomass for the EU Bioeconomy


Due to the incoherent nature of the EU BE political framework, the various BE sectors are characterised by differentrequirements and preconditions such as mandatory or voluntary sustainability criteria as well as the politicalstrategies for the development of the respective sectors. Amongst others, the lack of coherence can foster leakeageeffects such as the intensively debated problem of indirect land use change (iLUC), potentially resulting from EUbiofuel policies. During our work in STAR-ProBio, we have identified the most relevant parameters driving iLUC risksin the existing literature. These parameters, together with existing approaches for the certification of low iLUCbiofuels (e.g. from the RSB certification scheme) will be used to develop a comprehensive certification module forthe assessment and certification of low iLUC risk biomass to be used in the EU BE.

The Contribution of the New EU Bioeconomy Action Plan to the UN - Sustainable Development Goals(Sdgs)


This paper fits well in Topic 4, section 4.1 Sustainability and socio-economic impacts. Indeed, it looks closely at theEU Bioeconomy strategy in its operational form: the action plan (updated in October 2018). The EU Bioeconomystrategy aims at sustainably developing the production and use of biomass in its primary and processed form inEurope. Therefore, by linking the different actions of the strategy and their corresponding SDG targets andindicators, this study puts the EU Bioeconomy strategy in the global framework of the SDGs that has become thenew framework for sustainable development assessments. It results an assessment of the EU bioeconomy strategyto sustainable development in all of its dimensions (environmental and socio-economic). Finally, the identification ofsynergies and trade-offs between bioeconomy actions informs on the overall coherency of the strategy.

Hydrothermal liquefaction 1, 3CO.15 ROOM 5B


Hydrothermal Carbonization of Refuse Derived Fuel


Efficient energy recovery from wastes can be achieved by the production of waste derived fuels such as RefuseDerived Fuel (RDF), which is the broad designation for fuels obtained from waste and not obeying to specifictechnical characteristics. RDF often presents a high degree of heterogeneity that influences their physical andchemical properties such as calorific value, moisture, ash, and chlorine content, and limits their application inthermochemical conversion processes [1]. In order to optimize RDF applications as a raw material for combustion,pyrolysis or gasification, some RDF properties, such as apparent density and calorific value should be increased,while moisture, ash and chlorine contents should be minimized. As such, hydrothermal carbonization (HTC)represents a feasible alternative as an upgrading technology, by producing an hydrochar with enhanced fuelproperties when compared to the original raw material.

From Spent Coffee Grounds to Renewable Diesel: Solvent Extracted Bio-Oil Versus HydrothermalLiquefaction Bio-Oil as Feedstock


This study focuses on the upgrading from spent coffee grounds (SCG) to bio-oil, followed by a further upgrading ofthe bio-oil to renewable diesel. Two methods of upgrading to bio-oil were considered, namely extraction of the bio-oilby means of solvent extraction, and by means of hydrothermal liquefaction (HTL) of the SCG. These two types ofbio-oil was compared to each other, both quantitatively and qualitatively. The solvent extracted bio-oil had a loweryield (11.7 wt%) when compared to the HTL bio-oil (28.5 wt%), but a slightly higher calorific value (39 MJ/kg versus36 MJ/kg). The extracted has succesfully been upgraded further by using hydrotreatment to obtain a high qualityrenewable diesel (97 wt%). Current experiments are conducted to hydrotreat the HTL bio-oil. These two pathwayswill then be compared.

The Fate of Organics During Catalytic Hydrothermal Gasification


Hydrothermal liquefaction (HTL) is emerging as innovative technology to produce renewable transportation fuels.The energetic valorization of the remaining soluble organics in the HTL water phase could be achieved throughcatalytic hydrothermal gasification (cHTG) or anaerobic digestion. The description of the fate of organic molecules iscurrently not well understood at the molecular level for cHTG. The analysis, using high-resolution massspectrometry, shade light into the fundamental chemistry of cHTG and will be presented in detail.

Two Stage Catalytic Hydrotreatment of Highly Nitrogenous Bio-Crude from Continuous HydrothermalLiquefaction: A Rational Design of the Stabilization Stage, with Higher Yields and Drop-In Potential


Our contribution leads to the reduced coke formation and decarboxylation/decarbonylation reaction pathways duringcatalytic hydroprocessing of HTL bio-crude. This is achieved by operating at milder conditions in 1st stage(stabilization stage) and severe conditions in the 2nd stage (drop-in stage). Results showed 100 % removal of O and93 % removal of N heteroatoms after the 2nd stage with enhanced H/C molar ratios and higher heating values(HHV). Simulated distillation (Sim-Dis) shows ~ 75 % of the upgraded bio-crude below diesel range (340 °C) for bothalgae and sewage sludge.

The Effect of Temperature on Yields, Oil Quality and Composition in Catalytic and Non-Catalytic LigninSolvolysis with Formic Acid in 5-L Scale


Lignin is a low-cost, widespread, renewable by-product from pulp- and paper and bioethanol production, and thusan attrective feedstock for valorisation. The Lignin-to-Liquid (LtL) process using water and formic acid as reactionmedium promotes very efficient conversion of lignin to monomers.In this work, The lignin conversion efficiency istested under catalytic (using Goethite and Ruthenium on Alumina) and non-catalytic conditions at 305 °C and 350 °Cin aqueous solvents under stirred conditions in a 5 L pilot reactor. Oil yields differ with operating temperature,presence/absence and type of catalyst. Overall, higher oil and char yields are obtained at 305 °C. More than 63%weight of the lignin can be directly recovered as oil at both operating temperatures using Ruthenium on Alumina ascatalyst.

Combining Lignocellulosic Ethanol Production and Carbon Storage - Towards Net-Negative-EmissionBioethanol?


The combination of bioethanol production and CCS (BECCS) is seen as a promising approach that could contributeto the removal of carbon dioxide (CO2) from the atmosphere. This study performs a life-cycle assessment that takesinto consideration all aspects of the ethanol production chain (from cradle to grave) and the additional inputs andbenefits of the BECCS approach.For the analysis, a Croatian biorefinery project currently under development servesas case study and contributes to the practical relevance of the results. The results emphasize that approachescombining BECCS and low-input feedstocks, such as miscanthus, could play a crucial role in climate changemitigation scenarios of the transportation sector. Under certain conditions, net-negative emissions may even beattainable for bioethanol.

How Country Specific Targets for New Infrastructure Can Affect the Eu Biomethane Uptake in Road Sector


The current status of deployment of CNG and LNG refuelling infrastructure for road transport is presented in thispaper. Based on the National Policy Frameworks notified to the European Commission by the Member States, asrequired by the Directive 2014/94/EU on the deployment of alternative fuels infrastructure, we discuss how thenatural gas uptake in road transport at EU level could be influenced by the future infrastructure national targets andestimated vehicles objectives as well as by the support policy measures envisaged to achieve them. The MemberStates’ strategies are analysed from the point of view of their coherence and level of ambition. Eventually, it is worthnoting that the real market deployment of this potential will be determined by both the energy market conditions andby the Member States’ capability to stimulate the industry by a coherent set of supporting initiatives. The paper aimsto quantify the EU production potential of Renewable Natural Gas for a road demand scenario and compare it withthe current infrastructure situation and forecast for 2020, together with an analysis of support measures toinfrastructure/fuel use development.

Isolation and Characterization of a Novel Cellulolytic Activity from a Hot Spring ThermophilicAlyciclobacillus Sp.


Extremophilic microrganisms have received considerable attention as sources of thermostable enzymes resistantand active at harsh operative conditions required by many industrial processes. This research has been focused onthe screening of extremophilic bacteria from hot springs of Lagoa das Furnas on the island of São Miguel (Azores,Portugal) and in particular a cellulolytic microbial strain was isolated and identified as belonging to theAlicyclobacillus genus. The microorganism, growing at 60°C and pH 3.0 in solid and liquid culture containingcarboxymethyl cellulose as carbon source, exhibited high level of an extracellular endo-glucanase. Moreover, thekinetics of bacterial growth and extracellular cellulase production were evaluated followed by the partial enzymepurification and characterization. The enzymatic crude extract showed its optimal activity at 65°C and pH 4.0 andrelevant biocatalyst stability was assessed around these values of temperature and pH. The preliminary resultsindicated that the cellulase from this novel Alicyclobacillus strain can be certainly regarded as good candidate forenzymatic processes of cellulose hydrolysis.

A First Approach to the Use of Olive Stone for Bioethanol and Bioproducts Production in an OliveResidues-Based Biorefinery: Biomass Fractionation by Steam Explosion


The present work aims at evaluating the feasibility of integrating olive stones in a flexible and multi-productbiorefinery based in residues around olive crop and olive oil industry in Spain. Such a biorefinery would havebioethanol as the main product.To this end, and as a first step in the definition of the most suitable conversion process, thefractionation/pretreatment of olive stones by steam explosion is addressed. The effect of increasing temperature andthe use of acidic conditions in the pretreatment is assessed by the analysis of the fractionation of main componentsinto the solid and liquid fractions generated after pretreatment and calculation of mass balances. Moreover, theenzymatic digestibility and sugar release from the solid pretreated substrates was assessed by enzymatic hydrolysis(EH) tests at laboratory scale using a commercial cellulolytic cocktail

Metabolic Analysis of Biobutanol Production by a Newly Clostridium Sp. Strain Wk with HighButyrate-Tolerant and Ph Independent Properties


Biobutanol produced through ABE fermentation employing the solventogenic clostridia has recently attracted aconsiderable amount of attention due to its similar properties to gasoline and high value served as a promisingbiofuel and chemical feedstock. In our previous study, a newly identified butyrate-tolerant Clostridium sp. strain WKwas discovered able to convert additional butyrate into butanol without pH regulation process. In order to explain thisinteresting observation, our current study was designed to investigate the capability of producing butanol byClostridium sp. WK using glucose and additional butyrate as substrates and further analyze the transcriptional leveldifference of relevant genes/protein through the reverse transcript quantitative PCR (RT-qPCR) and isobaric tag forrelative and absolute quantitation (iTRAQ), respectively. These study should establish a comprehensive map tobetter understand the molecular mechanism of butyrate re-assimilation phenomenon to further enhance thebiobutanol production by this novel and potential Clostridial strain.

Lignin Modification with Laccases Produced by Pleurotus Ostreatus


Lignin mofication is important in order to increase the cellulose accesibility in rice husk, however the complexmechanism is not clearly understood. Furthermore, laccase seems to have a strong affinity for lignin, and we foundthe enzyme in the solid substrate. Then, laccase presence in pre-treatment has to be regulated by the fungi. Finally,lignin presence has an effect in laccase activity.

Study of Rice Husk Biological Pre-Treatment with Pleurotus Ostreatus


Semi-solid culture for rice husk pre-treatment is an interesting strategy in order to produce enzymes, biomass andmodified substrate. While, hydrolized sugars are easily solubilizated, all phases of culture are well defined for itsseparation. Furthermore, we observed hight laccase and exo-glucanase activities. Finally, the complex structure ofrice husk suggests that slight changes in lignin by P. ostreatus enzymes are enough to increase cellulose access.

Interest on the production of second generation fuels is increasing, consequently, the study for the production ofenzymes used in the biological pretreatment of lignocellulosic biomass is also growing. An example is the study andproduction of laccases enzymes, involved in the lignin modification. The main organisms studied to producelaccases is the white rot fungi, such as Pleurotus ostreatus. For this purpose, the production of laccases by P.ostreatus in different synthetic culture media has been widely evaluated, and have been found that glucose is themain carbon source. However, the highest laccase activity values have been reported in culture media with coppersulfate. Moreover, an inductive and synergistic effect of laccase activity between copper and lignin has beenreported. Despite, the inducing effect of the laccase activity of other lignocellulose-derived components and theirinteraction with copper sulfate in synthetic culture is yet unknown. In this study, the inducing effect of laccase activityby different lignocellulosic derived compounds with copper or not was evaluated. The pretreatment of rice husk withdifferents laccases will be evaluated.

Biotechnological Furfural Production from Sugarcane Straw and Bagasse Mixture


Diluted sulfuric acid is one of the most pretreatments for lignocellulosic materials mainly due to its efficiency in theseparation process of cell wall components. The hemicellulosic fraction obtained after pretreatment of the biomasscan be converted into value-added chemicals such as xylitol, ethanol, butanol, succinic acid and furfural. Furfural is achemical that can be used in a variety of industries. It is generally produced from agricultural waste containingpentoses as the main component, as for example from corncob, straw and rice husk. Usually, furfural can beproduced in two ways. The first one is a hydrolysis process of the biomass into xylose, which is subsequentlydehydrated in furfural, both reactions occur simultaneously in the same reactor. The other, consists in a two-phaseprocess that begins with hydrolysis of the biomass into xylose in a reactor, followed by a second stage, a dehydrationreaction, which is carried out in another reactor to obtain furfural. The advantage of the two-stage process is that theresidue from process (cellulose) can be used for the production of other bioproducts (glucose, for example).

Microwave-assisted hydrolysis of giant reed hemicellulose in the presence of Amberlyst-70 asheterogeneous catalyst


Biomass conversion to sugars represents the basis of future biorefineries, because sugars can be converted tobio-fuels, bio-chemicals or bio-based materials through fermentative or chemical routes. In particular,second-generation sugars, derived from the hydrolysis of lignocellulose polysaccharides, are a renewable rawmaterial more sustainable than first-generation ones, obtained from the hydrolysis of food crops.A promising strategy to guarantee sustainable bio-based economy involves the multi-stage fractionation/conversionof biomass feedstock in order to maximize sugars recovery minimizing the formation of by-products. The present study is focused on the investigation and optimization of the sustainable microwave-assistedheterogeneous hydrolysis of giant reed (Arundo donax L.) in order to convert hemicellulose to xylose, which can beused as substrate for the synthesis of several products, such as xylitol, furans and five carbon alcohols.The employment of microwave irradiation together with a recyclable solid acid catalyst, such as Amberlyst-70, couldbe a sustainable alternative to the hydrolysis of biomass carried out with mineral acids or enzymes.

Biomass Alcoholysis To Butyl Levulinate And Valorisation As Additive In CI Internal Combustion Engine


In the recent years we have seen an increasing interest towards the use of biomass as renewable carbon source forthe production of chemicals and transportation fuels. In particular, lignocellulosic biomass represents an abundantand inexpensive renewable resource with high carbon sequestration ability and non-polluting.In this paper the valorisation of the solution butanol/butyl levulinate/ dibutyl ether (DBE) as additive fuel incompression ignition (CI) internal combustion engine (ICE) was studied. This mixture was directly obtained from thecatalytic alcoholysis reaction of the cellulosic fraction of raw and pre-treated lignocellulosic biomasses with n-butanol(n-BuOH).The mixture was tested as blend with Diesel fuel in a CI-ICE with the measurement of pollutant emission andperformance. Results have been compared with those obtained by fuelling the engine with a commercial Diesel fuel.The obtained results evidenced the potentiality of these novel blending mixture to reduce the emissions of particulateand carbon monoxide without any increase in NOx emission and negligible changes in engine power and efficiency.

Incidence of Flocculent Yeast Strains in Ethanol Production Process


This work assessed the incident of essentially flocculent strains during the 2016 season at an industrial fermentationunit that started the season with a strain selected from its own process (SM 584) and that does not have the ability toflocculate.The performance shown by SM584 of remaining in the process as dominant in 97% of the season period andreverting the situation and ending the season as dominant again reinforces that using as inoculum a strain isolatedfrom the own process can be an interesting strategy, mainly when we note the diversity of yeasts with flocculentcharacteristics that allow them to dominate the process in case another strain is used as inoculum.

A Comparative Study on the Pretreatment of Reed Using Dilute Formic Acid or Inorganic Acids for SugarRecovery


In the North of the Netherlands large amounts of reed are available from natural resources. The material is easy touse and can be stored in its harvested form for a long time without additional requirements. In contrast to e.g., grassor other fresh biomass, it can be processed throughout the whole year leading to smaller, more efficient refineryfacilities. The aim of the project is to develop pretreatment methods that are compatible with a number offermentation processes (e.g., ethanol, butanol, lactic acid).

Butanol Production From Sugarcane Molasses by Clostridium Beijerinckii Using Ph Controlling And GasStripping Techniques


Biobutanol is an excellent biofuel. It can be produced by fermentation process called acetone-butanol-ethanol (ABE)fermentation. One of the main problems associated with the ABE production is low product concentration andproductivity caused by butanol toxicity and product inhibition. In ABE fermentation, pH has been recognized as a keyfactor, and removal butanol during the fermentation using gas stripping technique may reduce butanol toxicity. In thisresearch, the effects of pH-control and gas stripping systems on butanol fermentation from sugarcane molasses byClostridium beijerinckii TISTR 1461 were studied to improve the ABE fermentation. The results showed thatpH-control experiment at 5.2 gave the highest sugar consumption rate and butanol production rate withapproximately 39 and 23%, respectively compared to those of pH-uncontrolled experiment. When a gas strippingsystem was connected to the fermenter, the butanol concentration, butanol productivity and sugar consumption wereapproximately 12 to 14% higher than those without gas stripping system.

Preliminary Study of Continuous Ethanol Fermentation Using Low-Cost Cell Recycling System


To maintain high cell numbers in a continuous fermentation, the fermentation with a low-cost cell recycling system(LCRS) was studied to improve the ethanol fermentation efficiency by Saccharomyces cerevisiae. The systemconsisted of a glass U-tube acted as a sedimentation column which was connected to a 2-L fermenter. A syntheticmedium containing 180 g/L of sucrose was first used as ethanol production (EP) medium. The continuousfermentation with LCRS was operated at 30 °C; dilution rate; 0.02 h-1; aeration rate in the fermenter, 0.2 vvm andrecycle ratio, 1. The results showed that the average sugar consumption (SC), ethanol concentration (PE) andethanol productivity (Qp) of the system with LCRS were 10, 32 and 31% g/L higher than those of the system withoutLCRS. When the juice from sweet sorghum stem was used as the EP medium with LCRS, the PE and Qp weresimilar to those using the synthetic medium. The results from this study clearly demonstrated that the continuousfermentation with LCRS was successfully used to improve ethanol fermentation efficiency, and the juice from sweetsorghum stem could be used as an alternative raw material for ethanol production.

Fractionation of Woody Lignocelluloses by Organosolv Pretreatment Using a Bench-scale Rotary Reactor


In this study, an ethanol-based organsolv fractionation of wood chips under mild temperature was evaluated using a20 L bench-scale rotary reactor without internal blades. Wood chips mixed with a solution consisting of ethanol,water and sulfuric acid for a solid-to-liquid ratio of 15% were treated predominantly at 140 ? for 60 mins with differentload fills (30-50%)and rotational speeds (2.5-25 RPM) of reactor. The removal of lignin from wood chips was foundto depend on load fill and rotational speed. With a 50% load fill and a rotational speed larger than 12.5 RPM, theremoval rate of lignin and hemicellulose can be up to 80% and 95%, respectively. Besides, the recovery rate of solidcellulose can be up to 85%, and the enzymatic hydrolysis efficiency of such cellulose can be up to 95% in 72 hr withan enzyme dosage of 15FPU/g cellulose. For adequate setting of load fill and rotational speed, mixing inside the 20L rotary reactor is supposed to be good enough for organsolv fractionation, demonstrating that such reactor can be agood choice.

Anaerobic digestion for biogas and biomethane production, 2CV.8 POSTER AREA


Anaerobic Digestion of Broad Beans, Maize Silage and Zephyr


There is need to investigate the suitability of various biomasses for energy production. Maize is the dominating cropfor biogas production in Latvia, but the latest government decisions restrict its future use. The cultivation of morevaried crops with good economics and low environmental impact is thus desirable. Lately, broad beans (Vicia faba)are used to improve the fields. However climatic conditions often fail to achieve the required quality. A study was aimed to find out the potential of biogas from waste of broad beans, which are not usable for food anddamaged zephyr and to compare with biogas production from maize silage. Raw materials were fermented into 16laboratory bioreactors in a single filling system at 38 oC. An average, digestion during 34 days yielded in 1,068l·kgDOM-1 biogas (0.542 l·kgDOM-1 methane) from broad beans production waste and 0.896 l·kgDOM-1 biogas(0.434 l·kgDOM-1 methane) from maize silage. From crushed damaged zephyr was obtained 0.209 l·kgDOM-1biogas (0.178 l·kgDOM-1 methane) and from co-fermentation of broad beans with maize silage was obtained 0.962l·kgDOM-1 biogas (0.475 l·kgDOM-1 methane).

Simulations of the Fluid Dynamics in a Scaledown Laboratory Digester


Among the components of a biogas plant, the stirring system represents the most energy intensive sub system andis therefore in terms of operation costs one of the main contributors to the negative budget of a biogas plant. Thus, avalid optimization of the mixing process allows a significant improvement of the economic efficiency. Investigationson mechanical mixing can be performed by laboratory scaled experiments or on full-scale plants. However, the latteroption is challenging and resource-intensive, i.e., limited safety, partial visualization, expensive instrumentation, time-and men power-consuming. Thus, it is helpful to conduct experiments at laboratory scale and/or using computationalfluid dynamic (CFD) simulations. In this contribution, this approach is presented.

Methane Recovery from Bioethanol Production Waste Using Nitrogen and Flue Gas ExplosiveDecompression Pretreatment


After bioethanol production a vast amount of biomass, mainly residual lignin, unreacted cellulose and hemicellulose,enzymes, yeast, and other components, are left as process waste. Therefore, this research aims to usenon-recyclable waste material from bioethanol to produce biogas, in an anaerobic digestion process. For this, theprocess waste is mixed with other substrate (sludge, manure, etc organic waste) and BMP (biomethane potential),assays are performed to evaluate its biogas potential and to find the most suitable conditions. This research will give an outstanding contribution to bio-based societies where we expect to be waste free, either byreducing its production or transforming it value-added products.

Single Autumnal Harvest Provides Higher Biomass and Methane Yield than Double Harvests of Giant Reed(Arundo Donax L.)


There is currently great interest on using the perennial grass giant reed (Arundo donax L.) as partial substitute ofmaize for producing biogas. Giant reed presents the advantages of low agronomic input requirements and highproductivity in the Mediterranean area. Moreover, giant reed can be harvested twice (in summer and in autumn), dueto plant regrowth ability at the expenses of the nitrogen stored in the rhizomes. However, this harvest practice is highnitrogen demanding, thus it merits to be further evaluated, considering biomass and biogas production, incomparison to a single autumnal harvest strategy. Our findings throw light on the opportunity to apply single ordouble harvest strategies to produce biogas from giant reed. Our results have also a practical relevance, owing tothe diffusion of biogas plants in northern Italy, and the interest of the stakeholders for the partial replacement ofsilage maize with giant reed for biogas production.

Biogas Potential, Production and Optimisation from Co-Digestion of Water Hyacinth, Municipal Solid Wasteand Cow Dung


Biofuels such as biogas have a potential to extend and diversify energy supply, thus reducing dependence onimported fuels and pollution levels. The search for appropriate models to be used in optimisation and control theoryis now a high priority to optimise fermentation processes. Major aspects in present-day anaerobic co-digestion,particularly interactions between system performance and co-substrate ratios for optimal biogas yields still remainunderdeveloped.

Improving Energy Efficiency in Small-Scale Biogas-Powered Solid Oxide Fuel Cell Systems by Co2Removal and Bidirectional Operation


In the frame of the project BioCORE we will develop, build and validate the performance of a small-scale biogasupgrading unit in combination with a solid oxide fuel cell system under realistic operating conditions at a biogas plant.The upgrading unit is developed to perfectly match the SOFCs requirements, thus reducing cost and increasingSOFC performance.Furthermore we will take advantage of the ability of solid oxide fuel cells to act as a solid oxide electrolysis cell(SOEC) if voltage is applied, thus working in reversible mode, whenever demand for electricity in the grid is low.Together with the separated and stored CO2 from the previous fuel cell operation mode, synthetic natural gas (SNG)can be generated and fed into the gas grid.

Energy Conversion of Polymeric Resides in Co-Gasification with Pine Biomass in a Downdraft Reactor


The present work studies the possibility of energy recovery by thermal conversion of electrical cable insulation, a rawmaterial that has the potential for gasification processes. The co-gasification tests were carried out in a downdraftreactor of fixed bed, at temperatures between 750 and 950 ° C and an installed power of 3 kW. Mixtures of 10 and20% of electrical cable insulation were used. The results obtained, demonstrate the feasibility of using thistechnology for the thermochemical energy recovery, with the ideal conditions to produce syngas with higher LHV(more than 5 MJ / Nm³) occurring in mixtures with 10% mixture of electrically conductive insulation.

Biogas2030 - Options for Existing Biogas Plants and Further Development of Biogas Production inGermany


By 2030, the fixed remuneration under the Renewable Energy Sources Act (EEG) will expire for a large number ofexisting biogas plants. At the same time, the share of fluctuating renewable energies in the energy system willincrease sharply. For the operators of biogas plants, this results in a variety of new requirements. The centralquestion for existing plants is still which economically viable options exist for the continued operation of biogasplants. In a research project commissioned by the Federal Environment Agency, the options for economically andecologically meaningful continued operation of the existing biogas plants by 2030 were examined and whichperspectives for the sectors transport, heat and electricity correspond to the expansion targets with renewableenergies and the national Climate protection goals. For this purpose, options for existing biogas plants wereidentified and possible plant concepts assessed both ecologically and economically.In the context of the article, the results of the project "Options for existing biogas plants by 2030 from an economicand energy industry perspective" will be presented.

Repowering as a Considerable Method to Adapt Operating Biogas Plants to Prospective Purposes inGermany


German biogas plant operators have to make case-specific decisions if a further operation is beneficial after 20years of operation. Therefore, the German government decided to extend the claim of remuneration to a further 10years in consideration of specific technical and operational system requirements and regulations defined by anamendment of the EEG in 2017. In this context, the present project examines a significant number of 14 well-selected biogas plants with variousdesigns and concepts to collect representative and comprehensive data of the plant conditions after long-termoperation periods. Based on the consolidated information and data collection, repowering measures and sustainablesystem concepts are developed to reveal prospects for existing biogas plants regarding technical equipmentreplacements, economic operation, ecologic impacts and socio-economic aspects.

A Techno-Economics Analysis of Small-Scale Farm-Based Anaerobic Digestion Plants in an Irish DairyFarm Context


Ireland has committed itself to a 20% reduction in greenhouse gas (GHG) emissions by 2020 compared to a 2005baseline. Based on current trends Ireland is projected to miss this target with a reduction of only 4% to 6% (EPA,2017). The agriculture sector has been identified as the single largest contributor, producing 32.3% of the totalemissions produced in 2016 (Environmental Protection Agency, 2018). Small-scale anaerobic digestion (SSAD) holds promise as an attractive technology for the treatment of livestockmanure and the organic fraction of municipal wastes especially in low population communities or standalone wastetreatment facilities. SSAD is particularly applicable to the Irish agriculture sector where the average dairy herd sizeconsists of approximately 80 cows in 2016 (Irish Farmers’ Association, 2017). Despite the apparent benefits ofSSAD the technology is still not well understood with much of the research previously conducted focused onlarge-scale systems. This study aims to examine the technical, economic and environmental considerations of thedeployment of SSAD systems in commercial Irish dairy farms.

Anaerobic Digestion of Enzymatically Treated Dairy Cow Effluent


In Portugal, cattle production increased up to 91,000 t in 2016 (EUROSTAT, 2016) and has been contributing to theincrease of methane emissions into the atmosphere. As an appropriate process for the treatment of organiceffluents, anaerobic digestion is ideal to minimize this negative impact since it provides the agricultural and energeticvalorisation of the substrate through the production of digestate and biogas. Heating, cooling and electricity supplyconstitute different applications for this energy carrier gas with a relevant social, environmental and economicimportance, mainly for the region and neighbouring areas where it is produced. Dairy cow effluent is an example oflignocellulosic biomass, whose recalcitrant compounds, such as lignin and phenols, must be previously hydrolysedand made available for subsequent anaerobic digestion. The use of laccase and hemicellulase may be of greatinterest as pre-treatment for a wide range of pollutant compounds of effluents (Kumar et al., 2017).

Advanced Biofuel from Waste Wood Integrated in the Steel Industry


Within the H2020 project TORERO (TORefying wood with Ethanol as a Renewable Output: large-scaledemonstration), a cost-, resource-, and energy-efficient technology concept for producing bioethanol from a woodwaste feedstock, fully integrated in a large-scale, industrially functional steel mill is demonstrated. Wood waste isconverted to biocoal by torrefaction, biocoal replaces fossil powdered coal in a steel mill blast furnace. Carbonmonoxide and hydrogen in blast furnace exhaust fumes is microbially fermented to bioethanol, while material andenergy loops of the process are closed to a very large degree. Every steel mill that implements this concept will beable to produce at least 80 million litres of bioethanol per year by using 120,000 t of waste wood by year. This projectcreates a value chain for wood waste, which currently has no high value applications. TORERO technology can beused to upgrade existing facilities of the steel sector. To assess the sustainability a Life Cycle Assessment (LCA) isused for the environmental assessment, furthermore a social Life Cycle Assessment (s-LCA) is applied, providingscientific indicators for social aspects of this new value chain.

Comprehensive Lca of a Jet-A1 Aviation Fuel Containing Different Renewable Kerosene


Sustainable biofuels for aviation with correspondingly high specific GHG reductions will have to provide a decisivecontribution to reduce emissions from air traffic and it is to be expected that airports in Europe will be supplied withJet-A1 that also contains renewable fuels of various types in variable proportions (“multiblend”). Against thisbackground the main objective of the DEMO-SPK project is to examine the behaviour of a multiblend under realisticconditions. The focus of DEMO-SPK is on the investigation of conventional Jet-A1, mixed with several bio-basedkerosene components. This includes beside technical analyses (e.g. fuel properties,) a comprehensiveenvironmental and economic assessment of the multiblend. DEMO-SPK offers the unique opportunity to addressopen questions directly related to the large-scale introduction of alternative aviation fuels, for instance the influenceon air quality at the airport and the potential reduction of overall life cycle emissions. In this context, a comprehensivelife cycle assessment (LCA) of the used multiblend has been conducted under consideration of actualmeasurements of local non-CO2 emission at the airport.

Thermo-Catalytic Reforming (Tcr®) in Demonstration Scale - Experiences from Scale Up


Bioenergy will play a major role in the energy transition as we head towards a CO2-neutral energy system. Biogenicresidues like digestate from anaerobic digestions plants, sewage sludge, composting residues, paper residues etc.are various examples of residue streams available for innovative applications. For the conversion of suchfeedstocks, Fraunhofer UMSICHT developed the Thermo-Catalytic Reforming (TCR®) technology for powergeneration and biofuel production. Starting from a lab-scale TCR®-2 unit (2 kg/h), to a demo-scale TCR®-30 plant(30 kg/h), the TCR® technology was scaled-up to a 300 kg/h plant for the conversion of sewage sludge at anindustrial rate.

Insights into Microwave-Assisted Low Temperature Pyrolysis Behavior of Biomass: A Kinetic and HotSpots Formation Study


Microwave-assisted pyrolysis (MAP) is a promising technology for biomass conversion, and it occurs at relatively lowtemperatures with a lower activation energy compared with conventional pyrolysis (CP), which means less reactionlimitation and energy consumption. However, few studies had investigated the kinetics and microwave induced lowtemperature behaviors of MAP. The aim of our work is to provide a kinetic study of MAP, and explain thelow-temperature behaviors and related microwave hot spots. A self-designed microwave thermogravimetric analysisdevice along with the isoconversional KAS method were used to explore the weight loss and average apparentactivation energies of wood sawdust and biomass components (cellulose, hemicellulose and lignin). Dielectricproperties of biomass were measured within the main pyrolysis temperature range to reveal the generation processof hot spots and explain the relationship with low temperature pyrolysis behaviors.

Algae-Based Wastewater Treatment in Western Germany


In view of the challenge of closing nutrient cycles, we have built an an easily transferable system for wastewatertreatment by algae. The so-called Algal Turf Scrubber is a low-investment technique, which can be coupled toagricultural or surface runoff, secondary sewage, or industrial wastewater streams, and may also serve inhigh-quality water treatment. Nutrient uptake efficiency and prevalent algal species were investigated in anexperimental system connected to waste water effluent of the local treatment plant, and the resulting biomass washarvested and will be tested for application as a soil conditioner, bio-fertilizer or input material for other processes.

Microalgae Cultivation Conditions in a Lab-Scale PBR for the Directed Photosynthetic Production ofDesired Products: the Light Spectrum Effect


In recent years, microalgae have attracted noticeable research interest as a potential renewable source for theproduction of several value-added products, including carbohydrates, proteins, lipids and pigments. Both microalgaeculture growth and their photosynthetic metabolites production rates are affected by many environmental factorssuch as nutrient type and concentration, CO2 availability, temperature and light (type, wavelength, intensity andphotoperiod). The aim of this study is to assess these factors, giving special emphasis on the wavelength of artificialLED light, with respect to their effect on the growth and content/productivity of the desired products in microalgaecultures, with the prospect of employing the proposed cell factories in a biorefinery plant. Batch experiments were conducted in order to quantitatively and qualitatively designate the effect of intensity andwavelength (blue, red and white) of LED light combined with optimally selected cultivation conditions on the cultureof Stichococcus sp. in a 5 L laboratory scale photobioreactor.

Hydrothermal pre-treatment of the microalgae Scenedesmus obliquus: an approach for selectivefractionation for biorefinery applications


Microalgae are one of the most innovative promising biomass sources for biorefinery applications, as this type ofbiomass has been widely studied for the production of biofuels, mainly biodiesel from microalgae oil, and also as asource of bioproducts, namely pigments, protein, amino acids, and fatty acids. However, wastewater-grownmicroalgae might have a limited access to high-value applications and in order to make the best use of this biomassresource it is crucial to perform a specific biomass fractionation in order to enable its easy upgrade in the biorefineryframework. In this study, the autohydrolysis pre-treatment was studied and optimized using the microalgae Scenedesmusobliquus, grown in 70 L vertical photobioreactors containing non-supplemented secondary brewery wastewater asculture medium. The effects of the hydrothermal processing on the hydrolysis of polysaccharides and on proteinsolubilization were evaluated. Furthermore, results for combined physical, chemical, and enzymatic methods for theselective product extraction on this type of biomass are also presented and the strategies leading to higher sugars(and protein) yields from biomass are also discussed.

Efficient Production of Bio-Oil by Marine Microalgae Schizochytrium Sp.


The high production cost of heterotrophic microalgae oils can be reduced by developing efficient strategy offermentation and decreasing production cost. We isolated a novel oleaginous Schizochytrium sp. containing a highcontent of docosahexaenoic acid (DHA). To improve the efficiency of bio-oil, microbubble sparger was equipped on5 L fermentor. The oxygen transfer rate was increased approximately 8.6-fold in the same condition. Along withoptimized fermentation conditions, the best bio-oil yield and productivity (38.9 g/L and 405.2 mg/L/h) were obtainedvia fed-batch fermentation. Additionally, to reduce the bio-oil production cost, corn steep liquor (CSL) was used asole nitrogen source for replacement of yeast extract. In fed-batch fermentation using CSL, the best bio-oil yield andproductivity (38.5 g/L and 401.0 mg/L/h) were similar with the experiment using yeast extract as a nitrogen source.Thus, the production cost of bio-oil can be reduced. It was possible that CSL is successful substitution of nitrogensource. This study presents an efficient strategy for the production of bio-oil by heterotrophic microalgae.

Preliminary Studies of Micosporines for the Creation of Reducing Creams and Solar Blockers Based onAlgae Porphyra Spp, Magellan (Chile)


In coastal environments, algae are subject to variations in radiation, salinity, temperature, desiccation, among others.Many individuals of algae can tolerate these variations thanks to synthesis of multipurpose secondary metabolites,such as mycosporins (MAAs) in red algae. The main function of these compounds would be photoprotection againstUV radiation, as accessory pigments, intracellular nitrogen reservoirs, antioxidant, prevention of photoproductformation and possibly as osmotic regulators. The synthesis of MAAs would be related to specific wavelengths aswell as the presence of nitrogen in the medium, among other factors still little studied. The hypothesis that guidesthis work is that the variation in the salinity of the medium will promote an increase of MAAs regulating the osmoticpressure of the cells. Thus, the objective of the same is to determine if the variation of salinity promotes thesynthesis of MAAs in Porphyra spp cultivated in light and dark. In this way the hypothesis is accepted, that is, thatthe variation of salinity promoted an increase in the concentration of MAAs at 40 and 45 PSU.

Direct Vacuum Drying Technology


The aim of the research is an observation of a heat transfer in a processed wooden biomass, especially woodchips.The heat transfer between heating medium and dried material is a vital parameter for the construction of drying andprocessing technologies. Vacuum conditions positively influence the heat transfer, yet the technology is limited dueto closed chambers and separation of heating medium and dried material. Drying of wood chips is characterised bya high demand of energy, which means that the heat transfer is enormous. Area of interface between the driedmaterial and the heating medium is limited basically by construction. A direct contact of the medium and the driedmatter is the way of maximizing the heat transfer. The improvement of that aspect is the goal of the research. Totaldrying efficiency is moderated by critical vacuum condition, optimal volume flow and direct heating by medium. Theefficiency of principles is tuned by analytical and numerical simulations.

Evaluation of Screenig and Drying as Process Steps to Improve Fuel Properties of Low Quality Wood Chipsfor Use in Small-Scale Gasifier-Chp Plants


Small-scale, decentralized wood gas CHP plants might strongly contribute to the transition from the use of fossilfuels to renewable energies. However, considering limita-tions in sustainable wood supply chains and a growingcompetition for wood for material use (e. g. for biorefinery processes), biomass residues from circulatory andcascade might increasingly be applied in small wood gas CHP plants in the future. Due to the high hetero-geneity ofsuch low quality woody fuels and their overall higher content of combustion and gasification critical fuel propertiescompared to currently used qualityclean woody biomass assortments (i.e. stem wood),failure-free plant operation isa major challenge. Therefore, flexible, efficient and cost-effective secondary fuel processing steps such as screeningand drying were tested in the research project "VergaOpt" to improve wood chip properties. Af-ter processing, theseupgraded fuels were applied in several commercially installed wood gas CHP plants.

Comparison Between the Values of Sintering and Deposition Predictive Indexes and the ExperimentalResults from Agropellets Combustion Tests.


Main constituents found in agricultural crop residues, especially their inorganic matter (ash), are linked to sintering,agglomeration, deposition, corrosion and erosion, which minimise both thermal efficiency and the lifetime conversionunit. One of the ways to reduce the problems associates to combustion of the herbaceous biomass is to mix it with woodybiomass. The use of adequate mixed-pellets made up of herbaceous and woody agricultural biomass residues(agropellets) in conjunction with an adequate selection of air excess can help to palliate them. The development ofmixtures that minimize these problems can allow to increase the use of these fuels that present a great potential.In order to solve this key aspect, many indexes have been developed which use fuel composition to predict or detectbehaviour or tendencies related to ash issues. If these indexes are able to correctly predict the behavior of a fuel,mixtures could be formulated that would minimize the problems. The objective of the work that is going to bepresented in this paper is to compare the predictive indexes values for four fuels with the results obtained inexperimental tests to the same fuels.

Production and Characterisation of Pellets from Rice Straw and Rice Husk


For the purpose of this work, the pelletisation of residues from rice harvest (i.e. straw and husk) was performed andthe main properties of the products were evaluated. Pellets were produced in a commercial pelletiser with amaximum capacity of 200 kg/h from the local company Nova Pellet (Novara, Italy). The raw materials were collectedfrom a nearby farm and left to air dry. No ligand was necessary as moisture was in the range 10–12%. The samples were characterized in terms of their physical, chemical and physico-chemical properties. In addition,their mechanical performance was assessed by means of axial and diametral compression tests and durability tests.All the analysed properties were compared with the established quality standards for wood pellets.

Integration of Biogas in Brazilian Bioethanol Plants to Increase the Production of 2g Ethanol


Global warming demands greater renewable fuels availability and the ethanol and sugar sector in Brazil stands out inthe productions of biofuels (1G ethanol) and bioelectricity. Recent studies also show a considerable potential ofbiogas production by biodigestion of vinasse and filter cake and the production of lignocellulosic ethanol (2G ethanol)using sugarcane bagasse. However, using bagasse for producing 2G ethanol would impact the energy matrix of theethanol plant, since this biomass is currently used in CHP systems. A possible solution for this is using biogasproduced from vinasse and filter cake biodigestion to replace bagasse, therefore increasing its availability to produce2G ethanol. This work aims to performs a technical and economic study of using biogas produced from vinasse andfilter cake biodigestion as a substitute to sugarcane bagasse, shifting it towards the production of 2G ethanol.

Copious amounts of biogas are produced by wastewater treatment plants and anaerobic digesters worldwide. As anemerging commodity, however, biogas is facing challenges that can limit its integration into commercial andresidential energy systems. As a sustainable alternative to current biogas scrubbing practices, the (re)use ofabundant steel-making residuals, commonly referred to as “slags” can be engineered to reliably remove hydrogensulfide and siloxanes from biogas. Proof-of-concept studies confirmed the potential of this by-product to serve as apotent biogas scrubbing media in a pilot-scale demonstration at the Boulder Wastewater Treatment Plant, Colorado,USA. The significant findings from this preliminary study manifested in the immobilization of 98% of influent H2S,treating more than 13 m3 of biogas (with 1,000 ppmg H2S), and retaining 0.02 kg H2S per kg of slag media. Thisapproach will likely have immediate impact in the biogas recovery industry, such that it can be easily scaled in a“plug and play” scenario with current gas treatment infrastructure in a sustainable environmental paradigm.

Water impacts of Bioenergy production, 4DO.5 ROOM 5A


Significant Extension of Biofuel LCAs by Introducing Footprints of Phosphorus and Land Use


LCAs of biofuels have been published since the late 1980s. They covered so far several environmental impacts suchas greenhouse gas savings, energy depletion, ozone depletion, acidification, eutrophication, photosmog, toxicity andothers. Since a few years, some serious impacts concerning biomass production and use (and hence, biofuel pathways aswell) have been discussed to supplement the existing LCA impacts towards a more conclusive picture, namely:- Water footprint (including water scarcity)- Land use footprint (including land use quality)- Phosphorus footprintAll of them address a similar issue: they reflect resources which are in some areas and/or countries very limited,though obviously not all of them everywhere. That’s why complex methodologies are necessary to address theselimited resources well in a LCA. Up to date, there is no LCA of the whole range of biofuels published, which coversthese important impacts seriously and conclusive. At the upcoming EUBCE we want to close this gap.

Effect of Land Use Changes on the Sustainability Assessment of Biorefineries Using Dynamic Life CycleAssessment


Since the land use and land use changes is much debated issue regarding sustainability of biorefineries. The aim ofthe research is to compare the impacts created from biorefinery process in the case land use changes areaccounted in dynamic manner and to compare obtained impacts with “classical” LCA approach. In this study themodelling approach used will include coupling of life cycle assessment (LCA) with system dynamics methodology.System dynamics methodology would enrich possibilities of LCA, since this tool depicts interrelations of componentsin the systems studied.

Assessment of the Effects of Sugarcane Straw Removal on Watersheds Stream Flow


The use of biomass has shown promise as a source of renewable energy, significantly reducing greenhouse gasemissions (GHG), however, little attention is paid to the effects that the changes associated with the increase of thisproduction can generate in the water resources. Thus, in order to maintain the sustainability of bioenergy productionand the water security, it is important to avaluate the impacts of sugarcane straw removal in the water availability onwatersheds.

Trade-offs and synergies between carbon, hydrology and biodiversity impacts of biofuel production inBrazil


The objective of this study is to assess the spatial variation in the potential impacts of biomass feedstock productionfor the biobased economy on water, climate and biodiversity and analyse the spatial trade-offs and synergiesbetween these impacts. This is demonstrated for land use change dynamics in Brazil towards 2030 given anincrease in the global bioethanol demand and taking into account the developments in the global demand for othercommodities. Based on the land use change projections for a scenario with and a scenario without an additionaldemand for ethanol, the potential impacts on carbon, water and biodiversity are assessed spatially explicitly. Thecombined spatially explicit results of the potential impacts of an increased bioethanol demand on carbon, water andbiodiversity show synarchies and trade-offs and allow for the identification of the regions most at risk for adverseeffects.

Life Cycle Assessment of Duckweed Production and Bioprocessing in an Integrated Ecological WastewaterTreatment and Biorefinery Supply Chain


Duckweeds are efficient aquatic plants for wastewater treatment, due to their high nutrient uptake capabilities,growth rates, and resilience to severe environmental conditions. The high starch and cellulose, and low lignincontents of duckweed species make it an attractive alternative for conversion into biofuels and chemicals, as they donot require intensive pretreatment prior to saccharification, in contrast to lignocellulosic agricultural residues andenergy crops. Therefore, the conversion of duckweed grown as a byproduct of wastewater treatment into biofuelshas been previously studied through the thermochemical and sugar platforms of the lignocellulosic biorefineriesconcept. These prior studies have mostly focused on the technical viability of duckweed-based bioethanol productionusing laboratory- and pilot-scale enzymatic saccharification and fermentation experiments. However, theenvironmental implications of a duckweed biorefinery system are unknown. This study utilized life cycle assessment(LCA) as a tool to analyze the environmental impacts and energy consumption of an integrated ecologicalwastewater treatment and biorefinery system.

Novel Device Comb for the Production of Torrefied Pellet from Biomass Waste


The aim of this study is to develop an energy efficient device to use less energy associated with heat treatment. Thedevice is named COMB (Counter flOw Multi Baffle) and its main feature is a column. The characteristic of this deviceis that solid materials are injected at the top of the column and gas, which is a torrefaction medium, is injected at thebottom, and a number of baffles are attached on the wall to increase the contact efficiency of solid and gas. Torrefaction experiments were conducted on EFB obtained from Indonesia. Raw EFB was grinded and dried toproduce a pellet, which was torrefied using COMB. The experimental apparatus was BSU of capacity 15kg/h andtested at 250-350C. The amount of gas used was 1.5~3 Nm3/min. The experimental results showed that the calorific value was increased from 4,300kcal/kg to 5,700kca/kg.Hygroscopic property was changed from hydrophilic to hydrophobic from the experiments of 40 days under outsideconditions of sunny, snowy and rainy.

Development of a Transient CFD Model for Charcoal Production in a Discontinuous Batch Reactor andValidation With Measurement Data


In Austria, as in the entire EU, a considerable demand for biochar for various applications (barbeque, activatedcharcoal, biochar for soils, industrial applications, etc.) exists. Despite of existing raw material resources, the majorshare is imported from outside EU and often produced under inefficient conditions and at high emissions. Thecharcoal production based on pyrolysis is a challenging process, influenced by several parameters (temperature ofheating system, drying and heat-up in the biomass bed, pyrolysis behaviour of the biomass fuel, batch duration). Inorder to achieve high quality charcoal products out of different biomass fractions, these parameters have to beadjusted according to the composition, water content and density of the biomass used and a well controlled heat-upof the biomass in the reactor has to be ensured. Thus, optimised pyrolysis reactors for batch-wise charcoalproduction which enable the production of high quality charcoal under controlled carbonisation conditions and shortbatch durations are needed.

Preliminary Techno-Economic Assessment of Biomass Upgrading by Washing and Torrefaction


Based on experimental results obtained at pilot scale, three feedstocks were studied in a preliminarytechno-economic analysis to evaluate the feasibility of the biomass upgrading routes. These feedstocks wereroadside grass, wheat straw and miscanthus. Depending on the moisture content of the biomasses two lines wereexplored. Washing followed by torrefaction (prewash) and torrefaction followed by washing (postwash). All the testedmaterials could be technically upgraded on large scale to commodity fuels, with some limitations on the quality dueto still significant alkali content in case of the roadside grass. However, the roadside grass upgrading can beprofitable since a gate fee of about 20 € can be charged. Postwash was the best option in the case of driedbiomasses upgrading (straw and miscanthus). However, straw like biomass upgrading is not profitable unless a gatefee can be charged. This can be the case of residual straws from rice and sugar cane crops, upgrading the materiallocally and exporting it. Detailed description of the methods and the obtained results will be presented.

Biochars As Additives in Biogas Production From Food Waste


The last years have shown an explosion of interest about biochars. While the main application targeted continues tobe soil improving material, more and more studies explore other options, such as the combination of biochars withbiological processes like anaerobic digestion (AD) of food waste.Recent studies have shown that the addition of biochars in AD of food waste increased the biogas yield(Fagbohungbe et al., 2017). However, to our knowledge, the role of biochars has neither been addressed inimproving the trace elements bioavailability, nor in continuous AD process. The objective of this preliminary study is therefore to (i) to evaluate the ability of different types of biochar to leachtrace elements, and (ii) to evaluate the effect of biochar addition on continuous AD of food waste using an upflowanaerobic sludge blanket (UASB) reactor.

Pyrolyzed Biomass as a Carburizing Agent in Industrial Processes of Foundries to Improve the Co2Balance


Wind power plants or photovoltaic can actually not produce 100% CO2 neutral energy. This statement is based uponthe fact that this plants partially consist out of products from the iron and steel industry. Today it is not possible toproduce iron and steel without fossil resources. Fossil carbon is used to reduce iron ore in blast furnace. In foundriesfossil coke and coal are used to refined pig iron from the blast furnace to cast iron.The objective of this research is the substitution of fossil carbon in metallurgy processes with biomass. Thermalconversion by pyrolysis generates a solid product - biocoal. Characteristics such as high carbon content and lowcontent of volatile matter leads to a suitable biocoal to operate in iron and steelmaking industry. This can be obtainedby a controlled and optimized pyrolysis process.

Assessment of Pineapple Field Residue Valorisation in Costa Rica


More than 500.000 tons DM pineapple residue are produced each year in Costa Rica. The industry is underpressure to reduce its environmental impacts. One issue is the management of the crop residues. When the residueis incorporated into the soil it provides substrate for the development of the larvae of the blood-sucking stable fly(Stomoxis calcitrans) severely affecting cattle farming. We conclude that harvesting methods need to be introduced and markets need to be created that offer a solution forall the material. However, currently regulations are not in place to make it possible make biogas production andselling electricity or bio-CNG for transport which are the main options for adding value to the crop.

An Upgrade to Marginal Soils: Efficient Digestate Fertilization of Sida Hermaphrodita


Marginal soils are of great interest for the production of biomass as their use can avoid land use conflicts. Especiallycropping systems based on perennial energy crops like Sida hermaphrodita (hereafter referred to as Sida) andorganic fertilization via biogas digestates showed great potential for soil amelioration and the production ofsubstantial biomass yields. However, the establishment of Sida seedling remains a challenge. Digestate fertilizationshowed adverse effects on the root system of Sida seedlings and leaching of nutrients after digestate fertilization onthe marginal substrate is a high risk.We propose to mix digestates with an organic superabsorbent material (Geohumus®) before incorporating it into themarginal substrate. The material shall bind the digestate, prevent leaching and minimize the adverse effects ofdigestate on root growth.We conclude that the combination of digestate and superabsorbent materials has great potential to increase thesuccess of establishing Sida seedlings on marginal soils for biomass production.

Energy Characterization of Giant Reed (Arundo Donax, L.) Grown on Soil Contaminated with Copper. APreliminary Study


The use of energy crops on contaminated soils may allow the recovery of marginal lands providing renewable rawmaterial without subtraction of valuable soils to food crops. However, beyond the ability in removing thecontaminating element, an important aspect concerns the suitability of the feedstock for energy purposes. Thepresent study was conducted on giant reed (Arundo donax L.) plants grown in pot on soil artificially contaminatedwith increasing concentration (0, 200, 400, and 800 ppm) of copper (Cu). The plants were collected in winter at theend of the first year of grown. Goal of the study was to examine the influence of Cu on the main parametersassociated with energy use. To this aim, the plants were analyzed for the calorific values, the ash content, theelemental composition and potential yield of biogas estimated through Buswell formula.

Characterization of Agricultural Residues: Physical and Chemical Analysis for Energy Transformations


Among the lignocellulosic biomasses, the residues of agricultural crops such as prunings of olive trees, vines andhazels could be play a key role for the Italian agricultural sector. The aim of this work is to evaluate the physical andchemical characteristics of these residues in order to obtain information on the potential use in energy transformationprocesses such as combustion, pyrolysis and gasification. The analysis of biomass characterization included theevaluation of moisture content, ash content, volatile matter, fixed carbon, total solid, lower and higher calorific value,elemental composition in terms of carbon, hydrogen, nitrogen and sulphur contents. Preliminary results show thatthe agricultural lignocellulosic residues could be used as resource for combustion processes for production of heatand power or in pyro-gasification processes for production of syngas and biochar that represents a good soilimprover.

Poplar Wood From Srf for Pellet Production. Characterization of the Raw Materials Derived from 3 and 6Years Old Trees


This study examined the wood pelletizing process carried out using trees obtained from SRF poplar plantations. Inthis process, whole plants and stems (without branches) at the third and sixth year of vegetation were utilized. Thepellet produced using the 6-year-old poplar is of better quality than that obtained with the 3-year-old poplar in termsof bulk density, length and ash content. Furthermore, the use of the crown fraction (branches and twigs) in theproduction process seems to influence the physical parameters of the pellet, more than the energetic ones.

Residues from Harvesting of Tree Nuts: An Appraisal of Energy Value of Walnut and Almond Husks


In Italy permanent crops for nuts occupy around 284,000 ha (year 2011), often distributed in areas with extensiveagriculture. Usually, the edible nuts derive from the hardening of cell wall and are embedded into a series ofmembranes of different consistency like a ligneous shell and a fibrous husk which are discarded. To implement atthe best a more “circular” economy each source of biomass wasted by a production process should be assessed tounderstand its suitability for a specific option of reuse. In the present work, we focused the attention on the husk ofalmond (Prunus dulcis, Mill.) and walnut (Juglans regia, L.). Both co-products have been suggested for theextraction of antioxidants for nutraceutical and pharmaceutical applications. However, their use can be addressedalso to energy aims. In this study, the residual husks coming from the collection and processing have beencharacterized for the main energy parameters (moisture, calorific value, ash content, elemental composition) andthey were used to produce biochar through a laboratory-scale reactor.

Dissolution Kinetics of Corncob in Lithium Perchlorate Solvent System


Increasing concerns over environmental and geo-political issues on sustainability have driven industries to shift theirefforts to produce chemicals from renewable biomass especially lignocellulosic bio-waste. To improve theeconomical use of lignocellulosic bio-waste (e.g. corn cob), an efficient pretreatment route is required to make itscontent accessible to enzymatic hydrolysis to produce bio-products such as biofuels and bio-chemicals. The use ofmineral acidic (H2SO4) and alkaline (NaOH) media for pretreatment is very efficient but produces toxic effluents thatare not environmental benign. But designing an efficient operation unit for the pretreatment of the biomass dependson the understanding of the dissolution kinetics of the biomass. Against this background, this study presents resultsof the investigation of dissolution kinetics of corn cob in lithium perchlorate (LiClO4•2H2O), an environmental friendlymolten hydrate solvent system.

Use of Tropical Fruit Waste for the Production of Lignocellulolytic Enzymes and Fungal Biomass


Enzyme production plays an important role in the alternative energies perspective, since it consists of the use oforganic matter, microorganisms and waste for a safe, efficient, low-cost energy production and with lessenvironmental impact. In order to use the carbohydrates that are present in the biomass and adequate fractionationand degradation of the lignocellulosic structure through pretreatment is necessary. Lignicolous fungi such asPleurotus ostreatus produce a wide range of well-known enzymes that are useful in the pretreatment ofagro-industrial waste. Additionally, the fungal biomass obtained from this process serves as a promising source offood that could help resolve food scarcity problems around the world. In this work, the potential of enzymaticproduction and fungal biomass of Pleurotus ostreatus is evaluated using peels of banana, dragon fruit (yellow),gulupa, mango, pineapple, and the whole goldenberry fruit. From all of the residues pineapple and goldenberrypresent as clear candidates for biomass and enzyme production, reaching high activities, productivities and a fastgrowth rate associated with its consumption of sugars.

Milling of Materials on a Base of Cellulose


Materials on a base of cellulose have various forms and applications. They can appear in the form of wood chips,bark from trees, plants, peels of seeds or grains etc. Transformation of biomass into the form of small particles issometimes not quite easy. The main problem is that biomass contains long fibres that include water or other liquids,for example lignin, that cause a lot of problems with the cutting elements and the sieve of the mill. This paper dealswith size reduction of biomass in mills of various design.

New Insights in Hemp Seed Phenols and Polyphenols Through Uhplc-Esi-Qtof-Ms/ms Analysis


Hemp seeds are an extraordinary nutritional source and hemp seed oil (HSO) is especially rich in essentialpolyunsaturated fatty acids (PUFAs), vitamin E, and sterols. Indeed, whilst the high PUFAs abundance defines thehuge health benefits of HSO intake, it makes HSO turning rancid and deteriorating through oxidation. To preventthese side effects, antioxidant compounds, typical of hemp seeds, should be more favorably extracted. In particular,polyphenols are aimed at increasing HSO shelf-life and at improving its organoleptic features being able todeactivate and/or suppress harmful free radical species. Plant polyphenols, which are distinguishable on the basis of the number of phenol rings and the structural elementsthat bind these rings to one another, enjoy an ever-increasing recognition due to their antioxidant activity, which isable to efficaciously counter the ill-effects of oxygen metabolism in cells. Thus, maximizing polyphenol concentrationin HSO is the main objective to be pursued, and extractive conditions have to be optimized as high temperatures,commonly generated during cold-pressing extraction, could negatively affect both polyphenols concentration

Softwood Bark Valorisation - Why is There A Need to Consider Flow and Transformation of Contaminantsin Biorefinery Processes?


Bark is a large by-product from debarking logs at saw mills or pulp and paper mills. Today it is commonly combustedfor heat and energy production, but there are growing incentives to look into alternative valorisation routes for thisversatile resource. Barks chemical composition is highly species specific and varies due to geography, harvest andtransport methods. As the outer protective tree layer, bark accumulates contaminates e.g. heavy metals andpersistent organic pollutants (POPs). These contaminants will mitigate along with the bark through subsequentbiorefinery processing - it is therefore imperative to understand their flow and transformations when developingfuture biorefinery concepts. Softwood bark valorisation was compared in three biorefinery scenarios: co-combustion,gasification, and anaerobic digestion. The fate of POPs and heavy metals were mapped from process entry-to-exitfractions and data used for LCA. Results show that environmental impact assessment of selected biorefineryprocesses provides criteria for evaluating specific valorisation pathways, which may circumvent potential challengesin downstream processing.

Thermal Characterization Using Tg-Ms of Brewers’ Spent Grain from Craft Beer


Manufacture of craft beer is an increasingly significant sector in Spain. It is characterized by its limited production insmall familiar factories. The management of brewers’ spent grain (waste generated in its manufacture) presents animportant limitation for producers in this sector: the generated waste is not usually properly managed, as it lacksspace and conditions to store it.One of the ways to eliminate this waste is its thermal use. To know if this use can be viable, the characteristics ofthis by-product must be analyzed.In this work, thermal properties are studied using thermogravimetry and mass spectrometry (TG-MS) technologies tostablish the possible use of brewers’ spent grain from craft beer through thermal use. To this end, samples aresubjected to different heating ramps in different atmospheres, obtaining various thermal parameters and emission ofpollutants.

Demonstration Tests on Horse Manure at Energy Production Plant


The entrepreneurs in the horse sector in the South Savo region have had major problems with regard to theprocessing of horse manure. Large race- and riding-horse stables do not necessarily have fields where the horsemanure could be spread as fertiliser. At present, the organisation of the manure management system is a large costitem for the entrepreneurs, and this, in part, weakens their economic viability. In Finland horse manure was allowedto be used in energy production in November 2018. Demonstration tests showed that horse manure can be used asa raw material source for co-incineration. The quality of flue gases from the horse manure-peat mixture incinerationdid not differ significantly from peat incineration. Horse manure seems to be well suited as a source of bioenergy andfuel for co-incineration.

Pineapple and Banana Residues for Fiber Production: First Assessment for Biomass Harvesting andValue-Added Product Development


Pineapple is the second highest tropical fruit commercially produced in the world, around 25.1 million metric tonnes.Pineapple plant is widely cultivated for the fruit in tropical and subtropical regions of the world. The leaves ofpineapple plant contain approximately 3% of strong white silky fibres. These fibres can be extracted from the leaveseither by retting or mechanical means. The leaves are generally thicker and fleshy often with hard surface. However,the pineapple leaves go mostly as agriculture waste at present and no mechanized systems to harvest and deliverthe leaves to the processing plant still exists. Considering the rising of pineapple plantation across the world, thepineapple leaf fibers are being utilized for many purposes in different sectors of industries. Hence severalexperiments have been conducted to determine which type of value-added product could be provided, and theresults indicated that the better is to utilize it for fiber extraction. Cellulosic natural fibres from pineapple leaves areconsidered as a green alternative to the conventional polyethylene (PE) soil cover in agro-industry or a possiblefeedstock for textile purposes.

Biobased Electrode Materials from Corncob Doped with Different Metal Oxides for Energy StorageApplications: Production and Characterization


Energy storage and conversion technologies such as Supercapacitors or Fuel Cells are crucial for the extensiveimplementation of Electromobility. In this context, the development of sustainable biobased electrode materials isjust as important. Via pyrolysis, an environmentally friendly and simple carbonization process, combined with anactivation and functionalizing step, promising electrode materials can be produced out of different biomasses. Byapplying this process, it was shown that corncobs, for example, can be converted into highly porous and functionalactive materials which could substitute their fossil-based counterparts. By presenting the production process as wellas the physico-chemical and electrochemical properties of the obtained materials, new insights into the conversionof biomass into highly value-added materials for energy storage and conversion applications are given.

Hybrid Model for Ethanol Production Via Syngas Fermentation: Coupling Between aThermodynamics-Based Black-Box Model of Bacterial Reactions and Mass Transfer in a Large-ScaleBubble Column Bioreactor


The present study describes the construction of a mathematical model capable of simulating ethanol productioninside a 700 m3 bubble column bioreactor fed with gas of two possible compositions i.e., pure CO and a 3:1 mixtureof H2 and CO2. The model is composed of two parts: i) a black-box model for catabolic ethanol production andbiomass growth, and a ii) mass transfer model of the bioreactor. Thermodynamics are used to analyze the feasibilityof bacterial catabolic reactions and to estimate biomass yields, maximum CO and H2 uptake rates and the value ofhalf-saturation constants. The model predicted a better performance of the fermentation process when H2/CO2 are fed to the bioreactor.However, a balance between process stability and performance has to be met. The use of CO as additional energysource for catabolism could prevent H2 consumption from becoming unfeasible at relatively low biomassconcentrations, at the cost of poorer bioreactor performance.

Is it Possible to Produce Low Nitrogen Hydrolysate of Giant Reed Suitable for Single Cell Oil Production?


Microbial oil obtainable from the fermentation of lignocellulose hydrolysates represents a promising and sustainablesource for biodiesel or other biobased chemicals like biolubricants. Single cell oil (SCO) production by means ofoleagineous yeasts requires low nitrogen and sugar rich substrates. The lignocellulosic crop giant reed (Arundodonax L.) presents favourable characteristics, like high productivity, low input requirements, adaptability, however itsbiomass is relatively recalcitrant to hydrolysis even if pre-treated. Very few information is available on the possibilityto exploit giant reed biomass as substrate for SCO production. A recent study regarding the lipid production fromgiant reed biomass by the oleaginous yeast L. starkeyi, revealed a high sensitivity of this microorganism to inhibitorsgenerated during the acid hydrolysis. The alkaline pre-treatment was chosen with the aim of reducing the generationof inhibitors during lignin removal and of retaining most of the hemicellulose, so that the enzymatic hydrolysatecontained both hexoses and pentoses, that are exploitable by L. starkeyi.

Bio-Active Compounds in Grape Cane Extracts from Different Vitis Vinifera Cultivars


The grape and wine production generates large amounts of solid wastes whose management gives disposalproblems. However, these residues are rich in organic matter. The grape cane, deriving from the pruning process,represents the main solid waste from vineyards. This residue is undervalued although it has been shown to be agood source of high-added value bioactive compounds. Some of them, such as phenolic compounds, can beextracted and employed in food, cosmetic and pharmaceutical industries. The residues from three different cultivarsfrom Italian Campania region territory: “Aglianico”, “Fiano”, and “Greco” were used in the present work. The aim wasthe valorization of these wastes through the extraction of phenolic compounds and, at the same time, to outline aprofile of the polyphenols extracted from the canes of different Vitis vinifera cultivars. Because many factors such astemperature, extraction time, and solvent composition can influence the extraction process, this step is of crucialimportance. In the present work different extraction conditions were compared and the efficiency was established bythe estimation of the total phenolic content and HPLC analysis

D-Lactic Acid Fermentation on Brewers’ Spent Grain With Lactobacillus Delbrueckii Subsp. Delbrueckii


The aim of this work was the recovery of D-lactic acid of the starchy lignocellulosic biomass, brewers’ spent grain(BSG). Since BSG is the major by-product in the brewing industry, it is lignocellulosic waste, which is available inhigh quantities, for the conversion into added valuable components. In order to enhance the accessibility of thepolysaccharides to the enzymes, the BSG was pre-treated with steam explosion. Afterwards BSG was enzymaticallyhydrolysed. Optimisation of pre-treatment and hydrolysis was done following Response Surface Methodology. Biomass growth and lactic acid production of Lactobacillus delbrueckii subsp. delbrueckii on glucose, xylose,arabinose was characterised. Finally LA was produced on BSG hydrolysate.Lactic acid was successfully recovered from the starchy lignocellulosic material, brewers’ spent grain by convertingthe glucose present in the hydrolysate with yields of 0.98 g LA per g glucose consumed.

Sol Gel Coupling Adsorption Method for Extraction of High Purity Silica from Sugarcane Bagasse Ash forSolar Cell Application


Ultra-pure silicon is required in the development of solar cells for solar power application. But, the current method ofproducing the ultra-pure silicon is energy-inefficient and cost-intensive, making solar energy very unaffordable formany. However, the use of cheap silica source to produce silicon especially the use of biomass waste (e.g.sugarcane bagasse ash) could pave the way for developing a cost-effective protocol to produce ultra-pure siliconand thus makes solar energy affordable by many and thereby making realization of sustainable development goal(No. 7) achievable. In most tropical countries where sugarcane is grown at commercial scale, there are substantialquantities of bagasse ash-rich in amorphous silica. A simple low-cost chemical method for the extraction of puresilica from the ash is of importance since the conventional method to produce pure silica requires high energy, andthis could be instrumental to developing a cost-effective protocol to producing ultra-pure silicon. In this study, sol gelcoupled with adsorption method using an activated carbon was used to extract high purity silica from sugarcanebagasse ash.

Synthesis of Mesoporous High Purity Silica Particle from Rice Husk


Various biobased chemicals were synthesized from lignocellulosic biomass and showed its application in previousstudies. Relatively, using inorganic compounds from lignocellulosic biomass has not been receiving attention. Ricehusk contains high silica content, about 20%. Previous studies focused on only exctracting silica from rice husk.However, silica has a lot of properites and its properties decides its application. In this study, we synthesizedmesoporous high purity silica particles. The properties of mesopore and high purity are useful in its application.Therefore, the silica particles synthesized in this study could be used as a high value added material.

Combined Production of Hydrogen and Co2 from Biogas Via Sorption-Enhanced Reforming


Biogas production in Europe has significantly increased in the last decade. Biogas is used in combined heat andpower applications, or, upgraded to so-called biomethane, as transportation fuel or chemical feedstock. However,due the high methane content of biogas/biomethane, its conversion to green hydrogen via the reforming process isgaining increasing interest, for use as energy carrier in transportation or stationary applications in high efficiency fuelcells, or as a valuable bio-based chemical. Sorption-Enhanced Reforming (SER) is an emerging alternativereforming process with integrated CO2 separation which combines reforming, water gas shift and CO2 separationthanks to the addition of a solid CO2 sorbent. The key advantages are process intensification and higher hydrogenyield (95 vol%, dry basis) in one single step, compared to conventional steam methane reforming. Applied to biogas,since SER integrates CO2 separation, it has the potential to avoid the costly biogas upgrading step and to produceboth valuable green hydrogen and bio-CO2. In the present work, a study of the SER process using synthetic biogasas feedstock is presented.

Mucilage Extraction from Opuntia Spp for Production of Biofilms


Desertification processes are becoming a severe problem in areas like the Mediterranean and Central America.Crops able to survive in those conditions lead them to a high potential generation of resources and the developmentof other activities related to them.Crops like Opuntia spp, grows essentially in the tropical and subtropical regions,under arid climate conditions, preventing soil degradation and being helpful in the control of the desertificationprocesses. The cladodes have in its composition mucilage, a complex polymeric carbohydrate structure with theability to retard water loss and being able to form viscous or gelatinous colloids. Its gelling, thickening andemulsifying properties turn cactus mucilage useful to be applied in different areas such as cosmetics,pharmaceutical, and some other industries. In the food industry, it could find application in food packaging as ediblefilms and coatings because of its ability in forming a molecular network. Therefore, the aim of this work is to developan efficient and sustainable method to extract the mucilage from the cladodes with characteristics suitable to beused as a biofilm material.

Antioxidant and Whitening Activities of Regional Biomass in Jeju Island for Natural Cosmetic Materials


This study has been performed to investigate the antioxidant and whitening activities of four regional biomass inJeju, Korea and evaluate their potential as the natural cosmetic materials.A broad-leaf bamboo (Sasa quelpaertensis), a cactus (jeju cactus), a cactusfruit (jeju cactusfruit) and a brown alga(sargassum horneri) were used for the materials and the extractives were prepared by hot-water extraction at 80°Cand methanol extraction at 25°C.Methanol extractives showed the higher antioxidant activities than hot-water extractives. The methanol extractivefrom the broad-leaf bamboo is the best one for the antioxidant activity and its minimum inhibitory concentration 1.56mg/ml. The brown alga which was an environment issue material in Jeju isalnd showed the valid antioxidant activityby methanol extraction however the relatively high minimum inhibitory concentration, 25 mg/ml, raised the necessityfor the effective security and processing of the source material.As the result of whitening activity evaluation, only methanol extractives from the broad-leaf bamboo showed the validwhitening activity however the minimum inhibitory concentration was too high for the industrial app

Fermentation of Xylose-Rich Substrates by the Haloarchaeon Halorhabdus Utahensis towards HighValue-Added Bioproducts


Research that focuses on the use of high value-added bioproducts for industrial applications is essential for theimplementation of sustainable approaches forecasting a bio-based economy. The effective use of biomassfeedstocks, particularly lignocellulosic materials, in large-scale applications will evolve from innovative researchaimed at the development and implementation of biorefineries established for specific feedstocks. In this context, animportant step is the concept of fractionating biomass into its core constituents (cellulose, hemicellulose and lignin)for further enhanced valorization. Contrary to the valorization of cellulose fraction, which has been extensivelystudied, there is a gap in the valorization of the hemicellulose fraction (xylose- rich substrate) towards bioproducts. In this context, the present work aims to explore the ability of the haloarchaeon Halorhabdus utahensis (DSM-12940)to ferment xylose (or xylose-rich substrates) to high added-value bioproducts, such as pigments, exopolysaccharides(EPS) and polyhydroxyalkanoates (PHAs).

Surface Response Methodology towards Optimal Carotenoids Production by Gordonia Alkanivorans Strain1B


The process of obtaining carotenoids, mainly towards sectors that may influence the human health, such aspharmaceutical and cosmetic, is strictly regulated because of the potential toxicity of the synthetically derivedpigments. Thus, microbial pigments are in increasing demand since they are a promising natural and safe alternativesource for various industrial applications. Gordonia alkanivorans strain 1B is a fructophilic desulfurizing bacterium,which was also shown to be a good producer of carotenoids. However, its production abilities presented a greatvariation, depending on the conditions it was submitted to. In previous works, both the carbon source and sulfursource, demonstrated a great influence in the total carotenoid concentration, especially when combined with thepresence of a light source. So, in this study, a surface response methodology based on the Doehlert distribution for two factors (% of glucose ina mix glucose + fructose (10 g/L total sugars), and sulfate concentration) was used aiming to get the optimalcarotenoids production by G. alkanivorans strain 1B.

How to Improve the Environmental Impacts of Biobased Materials Development: Application Case ofBiobased Adipic Acid


Reducing environmental impacts, such as climate change, is one of the major challenges of today’s society. Indeed,the development of bio-based products, such as biofuels and biochemical products, can reduce the petroleumdependence as well as greenhouse gas emissions simultaneously (Hermann et al., 2007; Hottle et al., 2013; Patel etal., 2005). Adipic Acid has interesting potential because it is a versatile building block which have many applications.On the other hand, environmental of petro-based adipic acid and nitric plants account for about 5% of anthropogenicN2O emissions (IPCC, 2007). These motivated the development of production of AA based on renewable resourcessuch as lignocellulosic biomass (Vyver and Román-Leshkov, 2013). In order to determine the potential reduction, aLife-Cycle Assessment (LCA) was performed on the Bio AA upscaling from Levulinic Acid conversion, which isextracted from wood biomass. The presentation aims to show how the supply chain can influence of the locations ofproduction sites and energy sources can support decision-making for the devof the biomass valorization chain.

Holistic Approach to Predict the Ash Melting Behaviour of European Solid Biofuels


The objective of this work is to make a reliable prediction of the ash melting of different biofuels of actual or potentialrelevance in the EU utilizing a holistic approach based on a number of predictive methods combined withcombustion experimental tests of the fuels. A total of ten solid biomass fuels of actual or potential interest in Europe were initially selected for the study.Relevant physical-chemical tests of the biofuels were carried out by using ICP-OES for the determination of ashforming elements as well as X-ray diffraction and SEM for mineralogical compositions and morphologicalcharacteristics of the ash. Ash melting was determined according to CEN/TS 15370-1, and alternatively two sinteringindexes and two in house methods, so called “disintegration” and “sieving” methods were used. A secure prediction of the ash melting and sintering of solid biomass fuels is crucial for the characterization andproduction of solid biomass fuel and for the design of related high efficiency and low emission combustion strategies.

Practical Application of Edxrf Technology to Determine the Chemical Quality of Wood Chips


A good fuel quality of wood chips is significant for failure-free combustion and less emissions. Unfortunately, woodchips might become contaminated with mineral soil during the logging and chipping process. Currently there is noreliable quality management system for chemical quality of wood chips. In a previous study "biomass fuel indexes forthe contamination with mineral soil" (BFICS) were developed. The aim of this project is to apply an innovativeportable EDXRF (Energy Dispersive X-ray Fluorescence) in the process chain. The EDXRF was calibrated withpulverized standard samples of wood chips (n = 30) of different tree species, in particular spruce and pine. Thelinear correlations between the XRF and ICP seemed to be rather tight (R 0.98) for all critical elements (Al, Fe, Mn,K, Si). First results showed that the concentrations determined with XRF (standard variation 15 %) match up withICP results. The average deviation to ICP was for all elements below 12 %. Further experiments are currentlyconducted to improve data quality and to determine the influence of different particle size of the samples on thestability of the XRF measurement.

Pneumatic Transport of Torrefied Biomass in Dilute and Dense Phase


The present work will show the pneumatic transport behaviour of torrefied biomass, white wood pellets and coal asused in a pulverised power plant at different regimes including dilute phase (mass loadings 5 kg solids/kg gas) anddense phase (mass loadings 100 kg solids/kg gas). Complementary work on grindability and fluidization will beprovided for a better insight. About 25% less gas is necessary to transport torrefied biomass on dilute phase andabout 2-3 times more is transported in dense phase when compared with raw biomass. The fluidization tests showthat torrefaction conditions have to be adapted to the properties of the feedstock to obtain the desired results. Thepresent work pinpoints the role of particle morphology in the fluidization and pneumatic transport and how milledtorrefied biomass pellets resemble coal particles. For this purpose optical microscope images will be provided.

Agrophotovoltaics: Combining the Production of Biomass and Solar Energy – Seen from a Ghg Perspective


One promising solution to improve the land-use efficiency is Agrophotovoltaics (APV). APV combines biomassproduction with renewable electricity generation on the same area as a dual-use system. Hereby agricultural cropsare cultivated underneath a ground-mounted photovoltaics power plant. In this study a Life-Cycle Assessment (LCA) was conducted in order to assess the global warming potential (GWP)of APV. The LCA is based on an existing APV system at a farm in southern Germany in the region LakeConstance-Upper Swabia.Based on the results of the study, APV is a promising opportunity to reduce the greenhouse gas emission comparedwith conventional agricultural land-use.

Global Climate Change Mitigation Potential of Bioenergy with Carbon Capture and Storage


Bioenergy with carbon capture and storage (BECCS) can result in so-called net negative greenhouse gas (GHG)emissions and could thus strongly contribute to climate change mitigation. However, the production of bioenergymay lead to land-use change (LUC) emissions thus reducing the total negative emissions achieved by BECCS. AsLUC emissions vary depending on the original land cover, the appropriateness of feedstock cultivation for BECCSmay be very location specific. Here, we provide a fully geospatially-explicit global analysis of (negative) GHGemission factors (EFs) for BECCS, based on the LPJml global vegetation model and a literature analysis ofbioenergy supply chain EFs.

The climate impacts of using biomass depend on the substitution of usage options along the entire value chain. Themethod of material flow analysis enables the determination of direct carbon storage, the substitution betweenmaterial and energy use and their composition of raw materials. For the climate effects of wood combustion, itmakes a big difference whether forest wood or waste wood is used and whether it is used in private households orbiomass plants. The article presents a tool for differentiated determination of climate impacts.

Hydrothermal liquefaction 2, 3DO.9 ROOM 5B


A Helicopter View on Hydrothermal Liquefaction of Biomass in Continuous Plants: How to CompareResults from Different Studies?


Since the early attempts in the 1980s, a number of continuous hydrothermal liquefaction (HTL) plants have been runand documented in the open literature. Continuous plants are indeed necessary for the development of HTL on alarger scale. However, the degree of heterogeneity in this field is rapidly increasing: nowadays, documented studiesin the literature can range from very tiny devices to large commercial facilities. Additionally, continuous HTL hasbeen applied to a number of different substrates: wood, micro- and macro-algae, lignin, sewage sludge, manure andother organic by-products. Is there a way to navigate in this great variety? Can the documented results beinterpreted in some way and, most importantly, can they teach anything? This work tries to answer these questionsby showing a novel graphical approach to compare the results documented in the open literature. More than 200experimental points from around 40 different studies were analyzed, highlighting interesting trends. The developedmethodology could be proposed as a common paradigm to describe the performance of HTL processes, offering acommon tool to compare and critically understand the results.

Feedstock Dependent Phosphorus Recovery in a Pilot-Scale Htl Biocrude Production


The production of renewable drop-in fuels through hydrothermal liquefaction (HTL) is a promising step to overcomethe dependency on fossil oil. As common phosphate fertilizers are fossil based, the recovery of phosphate in a HTLprocess is improving the sustainability of the overall concept and adds value to the production chain. The presentstudy investigates strategies for phosphorus recovery from residual streams in biocrude oil production of threedifferent biomass feedstocks (Miscanthus, Spirulina, and sewage sludge).

Standardization Needs in HTL


Widely varying biocrude yields and quality data are reported in the HTL field. Often suchdata scattering is caused by differences in normalization on dry/wet, ash/ash free basis, aswell separation method – solvent type, gravimetric and others. Further, whereas HTLcrude oil resembles its fossil counterpart in many ways, there are distinct properties thatneed to be understood and addressed when applying standard methods intended for fossilhydrocarbons, in order to avoid significant misinterpretations.

The Impact of Marine Biomass Deliveries on the Truck-Transportation System Around the Power Plant


As marine transportation have high capacity, this generates interference to the local biomass supply chains, likedeliveries by trucks. A dynamic simulation model was developed to study this highly dynamic activity. The simulationmodel has been developed using agent-based modeling approach and includes a logic for truck-transportation chainincluding roadside chipping of forest biomass. Knowing interference gives the possibility to anticipate and plan the system to work optimally by designing aschedule according to sites requirements, manage storage beforehand and having the volume and frequency ofmarine deliveries optimal. As marine delivery needs room at storage, effective storage space is decreased as themarine delivery is ordered. This results in lower utilization of trucks as local deliveries are halted to prevent overflowof storage.

Harvesting Citrus and Olive Pruning Residues for Energy Use in Mediterranean Area of Italy


In South Italy, olive and citrus orchards cover about 918,000 and 145,000 hectares, respectively. The biomassproduced yearly in these agricultural systems has not been mobilized and used for bioenergy production. the majorityof farms considered pruning a problem rather than an opportunity and, hence, it is not used or incorrectly eliminatedin spite of the enormous available quantitative and potentially useful for several uses. This paper evaluated thetechnical possibilities for collecting residual biomass coming from pruning of Mediterranean fruit trees in order to beused as a source of energy optimizing the technology available for harvesting the agricultural biomass residues. Inparticular, several tests were carried out using a specific pruning shredder collector to determine variability oftechnical parameters (working width, harvesting speed, species, density, amount of pruning) lead often to a variedperformance and unit cost.

Biofuels from feedstock to biodiesel production, 3DV.6 POSTER AREA


The Production of Pyrolytic Jet Fuel from Biomass


Developing variable sources for replacing fossil jet fuel with renewable ones has been concerned as a main targetfor aviation green energy. The feedstock source should be able to reduce greenhouse gas and remove waste.Therefore, solid waste has been considered as a suitable source of renewable aviation fuel owing to its renewabilityand problems caused by incineration. In this study, the Miscanthus, which is a local troubled agriculture waste inTaiwan, was converted into products similar to traditional jet fuel through fluidized bed fast pyrolysis,hydro-processing and hydro-cracking/isomerization. A fluidized bed reactor was applied for turning the biomassmaterial into pyrolytic oil containing the groups of phenol, aldehyde, ketone, acid and alcohol. The pyrolytic oil wasthen converted into alkanes, toluene and cycloalkanes through hydro-processing in a fixed bed reactor. Thehydro-processed products was then hydro-cracked/isomerized into shorter chain alkanes, iso-alkanes andcycloalkanes in a fixed bed reactor. The chemical components of the fuel are confirmed via GC-MS/FID. The finalproduct which contains appropriate amount of normal, iso-, and cyclo-alkanes, i

Supercritical Ethanol Liquefaction of Lignin in A Continuous Reactor


In this work, we tried to develop a continuous reactor system for liquefaction of lignin to bio-oil in supercriticalethanol. A high-pressure slurry feeder was developed to deliver the feed made of lignin in ethanol to a tubularreactor. Two different type of reactors were tested to improve lignin liquefaction performance. Major reactionparameters such as lignin type (alkaline, dealkaline, kraft, and concentrated sulfuric acid hydrolysis (CSAH) lignins),reactor residence time, and reaction temperature were explored to optimize bio-oil production conditions. Ligninreactant and bio-oil product was characterized by proximate, ultimate, TG/DTG, and FT-IR analyses. Compositionalanalysis of bio-oil and gas products was also carried out by GC-MS and GC, respectively. CSAH lignin was the mostresistant to liquefaction in this work. Product distribution was sensitive to the variation in reaction temperature above350 oC at 350 bar.

One-Stage Bio-Oil Stabilization over a Sulphided NiMo/Al2O3 Catalyst


The upgrading of pyrolysis bio-oil is a crucial step before its further advanced use as a biofuel. Hydrotreatment is thepreferred upgrading process, but the tendency of bio-oil to form carbonaceous deposits and other negativeproperties causes catalyst deactivation and thus the gradual decrease in product quality. The deactivation of catalystleads to frequent termination of experiments after several hours/days of continuous hydrotreatment. All thoseproblems were recorded also for two-stage bio-oil hydrotreatment. We already reached a total time on stream (TOS)81 h of bio-oil hydrotreatment when different conditions were tested. Now, we decided to maintain the mostappropriate conditions (340 °C and 4 MPa) throughout the whole week over commercial sulphided NiMo/Al2O3catalyst designed for bio-oil hydrotreatment. We have succeeded in achieving 80 h TOS under the given conditionswithout an observable increase in pressure drop during the course of the experiment. This work provided valuableresults that will allow us further optimization of catalyst performance in particular to suppress its deactivation and,thus, extending its lifetime.

Obtaining Biodiesel from an Inedible Oil for Diesel Engines of Vehicles from the Amazon Rainforest


Biodiesel production from Jatropa Curcas in Peru is interest in the regional government of Tarapoto and otherregions of Peru. The advantages of the easy cultivation of this species make it possible to maintain a supply of rawmaterial for the production of biodiesel from Jatropha Curcas with a biorefinery processing perspective.Biodiesel can be produced at small and medium scale, having the potential to be an option for energy supply inisolated rural areas, especially in the Amazon rainforest. With the local production of biodiesel, the standard of livingin rural communities can be improved, reducing migrations and fixing the rural population in the countryside.Transesterification reaction defined the production of biodieselActually, concept of biorefinery in important for new plants of biodiesel. Where all waste (pulp of fruit, shell andcake) is used. The pulp of the fruit, the shell of the seed and the cake resulting from the extraction of the oil (whichcontains 56% of proteins), can be used for organic fertilization or for the production of more energy.We obtained biodiesel of Jatropha oil at 60°C in 40 minutes.

A Novel Approach on Isomerization of Long Chain Carboxylic Acids Basedo on Their Similarities withHydrocarbons


One of the most important aims of this research is to improve the cold flow properties of biodiesel to be able to blendit in petrodiesel in higher amounts. Isomerization is an excellent path to reduce the melting point of carboxylic acidswithout losing the oxidative stability. Depending on the position of the branch on the hydrocarbon tail of the fatty acidthis reduction could be up to 50 degrees centigrade which could be a breakthrough in biodiesel production industry.

Portugal National Day Conference


Current status of Bioenergy in Portugal Biomass in Portugal represents about 14% of the total primary energy consumption, which accounts to about 50% oftotal RES share. Portugal´s Southern European geographical location, in the cross of the Atlantic and Mediterraneanclimate zones, enables a diversified agricultural and forest production leading to a diverse biomass feedstock forbioenergy and bioproducts production. Currently, a major issue in the country is the prevention of forest fires througha sustainable forest management taking into consideration economic, environmental, and social dimensions. Before2020, five new power plants will enter in operation with a total of 71 MWe, with a total forest residual biomassconsumption of about 700.000 ton/year. Moreover, it is planned the promotion of decentralized small-scaleheat-producing biomass plants dimensioned for the locally identified heat needs (industrial heat networks, servicesor municipal equipment). The installation of advanced biorefineries is also being considered to fully deploy a fullysustainable bioenergy-based system towards the circular bioeconomy goal. The National Plan for PromotionBiorefineries (RCM nº 163/2017) is the national guideline for promoting next-generation biomass-based industriesfor 2030. This event will gather experts from industry and research into three sessions dedicated to heat and powerapplications, forest biorefineries, emerging technologies and biomass markets.

Tracking Sustainable Bioenergy Development: Focus on Africa


Current status of Bioenergy in Portugal Bioenergy production and use can make a valuable contribution to the sustainable development agenda. Withcareful management, various forms of bioenergy can help countries meet growing energy demand whileconcomitantly realizing carbon emissions reductions, climate change mitigation and adaptation efforts andimprovements to citizens’ livelihoods. These benefits are best obtained through effective monitoring, research andinformation sharing as they support the development of comprehensive national bioenergy policies. In this context, the sustainability of bioenergy has been approached in different ways and by different initiatives andorganizations. In 2011 the Global Bioenergy Partnership (GBEP), an initiative composed by over 50 governmentsand 26 International Organizations, published a set of 24 sustainability indicators for bioenergy. The indicatorscontain descriptions and annotated methodologies to guide countries in assessing the sustainability of their domesticbioenergy production and use. The GBEP indicators are currently in the implementation phase. As of March 2019, the GBEP indicators have beenimplemented in twelve countries (Argentina, Colombia, Egypt, Germany, Ghana, Indonesia, Italy, Jamaica, Japan,Netherlands, Paraguay and Vietnam) and Germany implemented the indicators for a second time. Four additionalcountries are currently in the process of implementing the indicators (Brazil, Ethiopia, Kenya and Uruguay). In light ofthe lessons learned, GBEP has developed an Implementation Guide on the use of the GBEP SustainabilityIndicators for Bioenergy to improve their practicality and provide related guidance for users. This side event will give the opportunity to share the experience of GBEP and other relevant international institutionsregarding the joint effort towards sustainable development of bioenergy with a particular focus on Africa. In this international context, IEA Bioenergy is working on the sustainability governance of the bioeconomy, andcontinuously contributed to respective GBEP activities over the last years. The work of the new IEA Bioenergy Task45 (Climate and sustainability effects of bioenergy within the broader bioeconomy,see http://task45.ieabioenergy.com) will continue collaboration with GBEP, and thus contributes to this side event.

Carbon Capture and Utilisation - Climate aspects, Technological status and Prospects for development


It is well known that CCS and CCUS are necessary, together with fossil fuels replacement, to reduce carbonconcentrations in atmosphere (IEA 2011, European Biofuels). Moreover, biofuels can play an important role toreplace fossil fuels, mainly when BECCSUS is added to the process, contributing to reduce carbon emissions and, inthe case of ethanol production, carbon capture from production process is a very interesting option in terms oftechnical feasibility and cost efficiency. Some existing experiences already exists such as the CCS at the corn-ethanol plant in Illinois, USA, supported bythe US Department of Energy. In Brazil, the most common use for CO2 for soft drink industries, which buy carbondioxide from some mills in the state of SP (for example, the Vale Onda Verde mill, at Nova Granada municipality).However, there are other possible uses, even with a higher added value. In Parana State, in Maringa, RaudiIndustries purchase CO2 from Copcana mill to produce sodium carbonate and to be fed in wood greenhouses aswell. The main and most profitable sources for CO2 production associated to biofuel production include fermentationprocess, upgrade process of biogas from vinasse and exhaust gases from the boilers. In the case of biogasupgrade, it is important to develop advanced technologies for vinasse biodigestion and for biogas upgrade. This isparticularly important in the case of sugarcane vinasse (a by-product of sugarcane ethanol). In this context, the main objective of the workshop is to present and discuss the perspectives for BECCSUS and theexisting experiences and challenges. The workshop will pay particular attention to the issue of science-based policymaking, discussing the best ways to use the most up-to-date scientific results in the policy making cycle to assessthe sustainability and mitigation potential of BECCSUS projects and applications. High-qualified speakers are invited, from Brazil, US and Europe, to present existing experiences and to discuss thechallenges. A recent Scientific Opinion on the climate benefits of the novel carbon capture and utilisationtechnologies, produced by the Group of Chief Scientific Advisors of the Scientific Advice Mechanism of the EU, aswell as the Evidence Review Report produced by the SAPEA consortium of European Academies that provide theevidence basis for the Opinion will be presented and discussed

EU-Japan biomass seminar - Sustainable value chains for distributed bioenergy projects


In recent years, the use of wood and wood residues for heat and power production from small-scale decentralizedplants has increased in Japan, thanks the adoption of a supportive National policy framework and to the availabilityof feed in tariffs for electricity. One of the technologies adopted is biomass gasification. Around 20 small-scalegasification plants are currently installed in Japan and more than 90 projects are in the planning phase, most ofthese installations are based on European technologies. Solutions are needed for adaptating those technologies tothe specific site conditions and for the efficient utilization of the forest biomass available locally, in order to ensure along-term sustainable development of this market sector. Building on the outcomes of the 1st EU-Japan Small-Scale Biomass Gasification Seminar held in Hiroshima inJanuary 2019, this event will gather experts from research and industry from both Europe and Japan, to discuss thechallenges and the solutions for the implementation of efficient biomass value chains for decentralized bioenergyprojects in Japan. The agenda will include presentations on the following topics: • Mobilization and storage of woody biomass resources: state of the art in Europe and Japan and applicability tothe local conditions. • Feedstock quality: biomass pre-treatment, characteristics and compliance with process requirements tomaximize the plant’s availability in local conditions. • Efficient use of residual heat: combined heat and power, biomass drying, district heating and locally applicablesolutions. • Processes, challenges and strategies for the valorisation of the solid and liquid by-products of small-scalebiomass gasifiers (char and wood vinegar) • A final roundtable with panellists from both Europe and Japan will discuss the opportunities for internationalresearch, knowledge transfer and industrial cooperation for sustainable decentralized bioenergy projects in Japan

Where will we get our biojet?


ICAO, the International Civil Aviation Organisation, has a target to cut carbon emissions in half by 2050. Whileefficiency improvements like more fuel-efficient aircraft and better air traffic logistics can bring about half of theemissions reductions required, the other half will have to come through renewable jet fuel. So if we hope to decarbonize the transport sector, we will need to have large amounts of biojet. It is possible to produce the biojet from a wide range of feedstocks, through a wide range of processes. Oleogenicpathways can use oil seeds from trees and oil-bearing crops like canola to produce kerosene from Hydro-processedEsters and Fatty Acids (HEFA). Carbohydrate crops like sugarcane and maize can be harnessed by conventionalprocesses to produce ethanol from sugar or starch and advanced processes to produce ethanol from stalks andstover, with subsequent upgrade to kerosene, in an ATJ (alcohol-to-jet) pathway. Wood pathways can use loggingand processing residues from forests to produce jet fuel through thermochemical conversion. Which pathways areused in different places will largely depend on which feedstocks are cheapest and most abundant. It will also depend on which conversion processes can be developed and commercialised at scale. This side eventwill explore the most likely pathways for biojet expansion and discuss the policies needed to put them in place.

Optimising value chains and ensuring the sustainability of advanced lignocellulosic biofuels with effectivesustainability criteria and verification


This side-event of the EUBCE is delivered by the Horizon 2020 project ADVANCEFUEL, and the EuropeanTechnology and Innovation Platform Bioenergy. It is open to all attendees of the EUBCE 2019. Advanced biofuels are expected to play a key role in the decarbonisation of the transportation sector in the EuropeanUnion. Policy support combined with a well-functioning system of sustainability criteria is required to foster themarket uptake of advanced biofuels, while also safeguarding the environmental and social sustainability. The recastof the Renewable Energy Directive (RED II), together with targeted support for advanced biofuels and bindingsustainability criteria for the whole bioenergy sector, is considered an important step forward. The sustainabilitycriteria for bioenergy defined in RED II initiate changes in national legislation at the Member State level as involuntary schemes. The legislation and voluntary sustainability certification bodies need to take into account that along-term development perspective is required, including defined means to actually monitor sustainability complianceof different bioenergy producers. Policy makers, voluntary scheme owners, and third party auditors need informationand guidance for implementing the defined sustainability requirements and to reliably safeguard their validation. Tofacilitate this, a harmonised and mutually recognised implementation and certification approach to the EuropeanMember States needs be targeted. Economic operators require information and guidance on how to provideevidence of compliance to the new sustainability criteria. Detailed information and guidelines are particularlyimportant for biofuel producers given the changes in feedstock uses, technologies, and deployment for theenvisioned increasing advanced biofuels market. This workshop engages expert speakers from research, industry, policy, and certification bodies to discusssustainability of advanced biofuels. In details the workshop will • Discuss sustainability criteria in the RED II and particularly emphasise the changes affecting efficient andsustainable production and use of advanced biofuels • Learn about the views of the European Technology and Innovation Platform (ETIP) Bioenergy representing manyimportant market players of the sector • Gather information from a policy and scheme owner perspective • Discuss and validate these findings by experts and stakeholders at the workshop • Identify the major sustainability issues and options for harmonisation of sustainability criteria and certification

Camelina & crambe oil crops as sources for medium-chain oils for specialty oleochemicals


The European oleochemical industry currently relies on imported coconut and palm kernel oils and fatty acids and oncastor oil as sources for medium-chain fatty acids (MCFA, C10–C14) and medium-chain polymer building blocks.These are needed for the production of plastics, surfactants, detergents, lubricants, plasticisers and other products.The COSMOS project, which runs from March 2015 to August 2019, aims at reducing this dependence by turningthe currently underutilised domestic oil crops camelina and crambe into profitable, sustainable, multipurpose,non-transgenic European oil crops for the production of oleochemicals. Seed properties of camelina and crambe have been screened and optimised through genetic techniques aiming athigh yield, low resource inputs, optimisation of the value generated from vegetative tissues and fatty acid profilesadapted to industrial needs. Large-scale field trials have been performed at different locations in Europe to assessthe potential of the crops in terms of cultivation practices, seed yield, oil content, ease of harvesting, and resourceinputs. Extracted oils have been fractionated into various fatty acid types for further uses and the press cakes havebeen fed to insects producing high-value proteins, chitin and fats. Insect fats and proteins will be isolated andprepared for use in food and feed products. The overall economic, social and environmental sustainability as well aslife cycle of the whole value chain will be assessed. The impact of the project for Europe will be assessed in terms ofvalue chain potentials for value creation and number of jobs that can be created. Towards the end of the project, the aim of this event is to present the research results of the project to a widerscientific audience. Presentations on the following topics are planned with regard to camelina and crambe: 1.Oilseed breeding and genetics; 2. Sustainable cultivation strategies; 3. Oil extraction and separation; 4. Vegetative tissue and seed meal valorisation by insects; 5. Integrated assessment of sustainability.

Novel and highly efficient micro-scale CHP system based on fuel flexible biomass gasification connected toa SOFC


Within the EU Horizon 2020 project “FlexiFuel-SOFC” (GA No. 641229) a new innovative, highly efficient and fuelflexible micro-scale biomass combined heat and power (CHP) technology (capacity range of 25 to 150 kW fuelpower) has been developed. By integrating a fixed-bed updraft gasifier, a compact gas cleaning system and a solidoxide fuel cell (SOFC), the technology has been developed to be capable of using a wide fuel spectrum (e.g. woodpellets/chips of various sizes and moisture contents, short-rotation coppice, selected agricultural fuels), while stillachieving high electric and overall efficiencies, as well as incomparably low gaseous and nearly zero particulatematter emissions – something almost unheard of in small-scale biomass systems. To realise this goal, thetechnology development (including process simulations, computer aided design, pilot plant construction,performance and evaluation of test runs, risk and safety analysis) has been complemented by a thoroughassessment of its techno-economic performance, environmental and social impacts, as well as market potential.This workshop will inform participants about the technical achievements of this exciting new technology, areas ofapplication, relevant impacts, as well as insights on how to bring this technology to the market.

Intensify production, transform biomass into energy and novel goods and protect soils in Europe


Future agriculture urgently needs to encompass the recovery of soils affected by pollution, degraded by drought,erosion, salinity, inadequate management or otherwise low productivity. A holistic view on the topic is needed for thefull potential of soils to be realized. a) Improving soils for agricultural purposes requires b) identification of crucial soil components and processes, both biotic and abiotic, c) assessment of plant species that sustainably produce high and safe biomass on marginal and/or contaminatedsoils and of plant-growth promoting microorganisms, d) selecting the optimum composition of organic amendments such as compost, biochar and digestate frombiogas production, e) using plants and their associated microorganisms to absorb or degrade pollutants, f) demonstrating potential of the soil for providing ecosystem services and for contributing to the circular economyin agricultural contexts. Involvement of citizens and stakeholders, including farms and farm-associated enterprises, is an integrated part ofthe solutions facilitating the implementation of sustainable and financially attractive production alternatives. Theholistic approach will encourage the implementation of production chains for sustainable intensification, which areadapted to environmental and socio-economic diversity within Europe. Our FACCE SURPLUS JPI project “Intensifyproduction, transform biomass to energy and novel goods and protect soils in Europe; INTENSE” has addressedthese topics. Our approach is to intensify agriculture within a sustainable framework, one essential part of thistransformation. Obviously, the keys for intensification is the status of agricultural soils and sound supply with water,structure forming materials and nutrients. Since soils, the fundamental medium for food production, are threatenedin many ways, the main question we want to answer are: 1) How can we preserve good soils? 2) How can we recuperate degraded soils and soils with natural low production potentials? 3) How can we preserve and develop the plethora of ecosystem goods and services of soils? In the EUBCE we present the key results, based on experimental evidence and analysis of options to intensify foodand biomass production by means of sustainable management tools.
