INTRODUCTIONINTRODUCTIONSUPPLY CHAIN FOR BIOFUEL

ECONOMIC ASPECT OF BIOFUEL PRODUCTIONECONOMIC ASPECT OF BIOFUEL PRODUCTION

Feedstock Production: comprises the cultivation of biomass resources such as corn, crop residues, and woody residues used as raw material inputs for biofuels production.

Feedstock Logistics: consists of harvesting or collecting feedstock from the area of production, processing it for use in biorefineries, storing it between harvests, and delivering it to the plant gate.

Conversion: This is an industrial activity in which the raw biomass is converted into biofuel along with one or more co products.

Distribution and retailing of finished fuels: This involves distribution of finished fuel for blending with fossil fuels. In the case of electricity, this involves the transmission and distribution of electricity to demand centers.

Consumption of bioenergy: This refers to the ultimate end use in which the biofuel enters the fuel tank of a vehicle or provides electricity

BioethanolProduction Costs

•The production cost for sugar beet takes advantage fromthe existing sugar and alcohol industry, so that the processing costs are the lowest.

•Two salient facts have to be underlined:-The most important share in the final cost calculations is attributable to the procurement costs of bio-mass. -The second salient fact is that the processing cost for straw is rather high.

Important factors:• The number of chemicals that are produced in the ethanol industry • Potentially even more in the 2nd generation bio-ethanol industry, serving a wide range of uses in the pharmaceuticals, cosmetics, beverages and medical sectors as well as for industrial uses. • The market potential for bioethanol is therefore not just limited to transport fuel or energy production but has potential to supply the existing chemicals industry

Bio-ethanol reduction costs are given according to the linear relationship:

Cost = 108 + 2.86*WP

where WP stands for wheat price.

Bioethanolvs. Conventional fuels• One of the biggest barriers to large-scaledevelopment of biofuels remains their higher economic costs compared to conventional fuels.Estimates show that bioethanol in the EU becomes competitive when the oil price reaches US$ 70 a barrel while in the US it becomes competitive at US$ 50 - 60 a barrel. For Brazil the threshold is much lower – between US$ 25 and US$ 30 a barrel.

•There are also differences depending on the feedstock used. •The current high oil prices mean that biofuels production have become competitive in some parts of the world.

Bioethanol

- Sugar cane ethanol in Brazil costs $0.30/lge free-on-board (FOB). Thiscost is competitive with that of gasoline at oil prices of $40-$50/bbl ($0.3-$0.4/lge). In other regions, costs can be more than $0.40- $0.50/lge, although potential exists for cost reduction.

- Ethanol from maize, sugar-beet and wheat cost around $0.6-$0.8/lge(excl. subsidies), potentially reducible to $0.4-$0.6/lge.

- Ligno-cellulosic ethanol currently costs around $1.0/lge at the pilot scale,assuming a basic feedstock price of $3.6/GJ for delivered straw (whereas cereals for ethanol production may cost $10-$20/GJ). The cost is projected to halve in the next decade with process improvement, scaling up of plants, low-cost waste feedstock and co-production of other by-products (bio-refineries).

Biodiesel

Different bio-diesel types:

•Esterificated oilsNon esterificated oilsWaste vegetable oil

The most common bio-diesel technology uses the so-called "transesterification" technique, a process that combines oils and fats with mono-alcohols in the presence of a base catalyst to form fatty acid esters (biodiesel).

Limiting factors:• feedstock prices• biodiesel production costs• oil prices• taxation of energy products.

BiodieselProduction costs

Two salient facts have to be underlined with respect to this cost structure:

• The large share in the final cost attributable to the procurement costs of biomass.

• The selling of by-products is a significant source of income that contributes to make the whole process competitive.

BiodieselTaxation

Partial or total exemptions on bio-fuels should be followed by an increase on the supply of raw material, and conditioned on a long term supplying commitment by farmers. As the development of technologies using cheaper raw materials increases, the total exemption could be unnecessary and should be modulated, depending on the economic results obtained.

Biodieselvs. Diesel

•It has been proved that at current production costs bio-diesel is not competitive against gas-oil.•Blends are a real opportunity for bio-diesel development, giving an appropriate income for farmers, competitive prices for final consumers and even providing a less polluting image to major oil companies.

IEA Energy Technology Essential of 2007

• Biodiesel from animal fat varies $0.4-$0.5/lde, biodiesel from vegetable oil is $0.6-$0.8/lde and biodiesel from BTL is more than $0.9/lde. • Biodiesel from animal fat is currently the cheapest option ($0.4-$0.5/lde) while traditional trans-esterification of vegetable oil is at present around $0.6-$0.8/lde. Cost reductions of $0.1-$0.3/lde are expected from economies of scale for new processes. The cost of BTL diesel from ligno-cellulose is more than $0.9/lde (feedstock $3.6/GJ), with a potential reduction to $0.7- $0.8/lde.

Biofuels has increased substantially in the EU. (quadruplicated to 2.4 million tonnes in 2004) (EurObserv’ER, 2005)

Targets for the share of bio-fuels. The Member States are free to choose a strategy to achieve these targets, i.e. use of biofuels in pure form (in fleets), in blends with fossil fuels, or a combination of the two.

Another way to produce biodiesel, is through micro-algae cultivation.

This way of production is still in experimental level, but the scenarios

and research on the field are quite promising and establish an

alternative production pathway for the future.

The economic analysis for biogas, it was derived, especially for the

farmers, that the production and the sale resulting by biogas, represents

an excellent investment useful for management to earn constant cash

flow to be used for current manage on the company. Farms, which

already receive incentives for their business, may receive other about

renewable energy.

There is a high expenditure of fossil fuels to create biofuels, from

transportation of feedstocks (i.e., corn) and the fossil fuels that are used

in the energy inten­sive process of creating nitrogen fertilizer, pesticides,

and powered irrigation. A full long-term ethical analysis would require

the impacts over generations of crops, generations of farming

communities, ecosystem survival and impact on any moral agent to be

consid­ered-
