Project Aims
• To produce at least one dicarboxylic acid in 2nd
generation biorefineries
• To develop downstream processing methods to purify
diacids from the fermentation broth at purities required
for polymerization
• To develop methods for polymerization of the selected
diacids to bio-based polymers
• To demonstrate and verify the fermentation process of
diacid production in a several thousand liter-scale demo
plant
• To evaluate the impact of biopolymers produced
through the BioREFINE-2G project through Life Cycle
Sustainability Assessment (LCSA)

S-LCA Summary
• Integration of S-LCA into original LCA model possible
• Visualization of results can point out hotspots
• We chose not to continue towards quantitative
indicators
• Within bioREFINE-2G: no established supply chain

Conclusions
• LCSA: three dimensions in one model is possible
• Different system boundaries are applied for LCA,
LCC, S-LCA
• LCSA has been a catalyst for ongoing discussions and
thus led to improved communication within theproject. The final project outcomes will benefit from
this process.

Outlook
• Further Refinement of all models
• Regionalized impact Assessment
• Anticipated highlight: Data Collection at BioRefinery
• Project Consortium looking for opportunity forfurther collaboration
• Project Consortium has grown confident in asking
life-cycle-related questions
