Meaning of bioREFINE - 2G

BIOREFINE - 2G approach

Utilisation of otherwise unused C5-wood sugars to produce diacids (throughengineered strains) as starting components for value-added biopolymers

Borregaard – Wood treatment

ULUND & DTU – fermentation strain

Identifiying a strain and a fermentation protocol toenable:

• Up take of C5 sugars

• high production of diacid

Optimizing genetic and regulatory processes

within cells to increase the cells' production of a certain substance

Biotrend - Purification

ecopol tech & AIMPLAS - Polymerization

ifu - Life Cycle Sustainability Assessment

Sustainability:

“Meeting current needs without

compromising the needs of future

generations”

Assessing the impacts of newly

developed process to ensure that

sustainability goals are met.

Sustainability

Goal of Life Cycle Sustainability Assessment

• fully understand environmental, economic and social impacts of products produced by the newly developed bioprocess

• report on the sustainability of the products to the funding association

• serves as a showcase on the newly integrated methods regarding economic and social indicators and impacts into the framework of an already established Environmental Life Cycle Assessment

• support the dialogue with the project partners on the method of a LCSA and to inform on preliminary results based on the most recent developments

Social Life Cycle Assessment

• Based on UNEP/SETAC

Guidelines

• Qualitative only

• Questionnaire forsite-specific assessment

• Literature research for specific

region/sector assessment

• Social Hotspot Database to assess supply chain

• Site performance good with very

low to low social risks

• Good performance for background

processes in norway

• Wood and chemicals supply should

be assessed specific when theprocess gets implemented

Conclusions

• LCSA: integrated modelling should be performed to enableassessments of processes in early design phase

• Preliminary results identified hotspots for ongoing processdesign improvements.

• Uptake of C5-sugars and production of diacid pose double challenge. Additionally complex wood sugar medium includingcontaminants and inhibitorsand requires improvements toenable sustainability goals

• Auxiliaries to condition waste streams need to be reduced. Production of diacid not yet implemented on scale-up. Assessment should be updated with ongoing improvements.

Thank you very much for your attention!
