Biorefineries at a glance

� »Biorefinery is an overall concept of a processing

plant where biomass feedstocks are converted and

extracted into a spectrum of valuable products.«

(US-DoE, E3 Handbook, 2000)

� Biorefinery concepts should fit to regional biomass

production characteristics

No. 7

Succinic acid = C4H6O4 = dicarboxylic acid

� Succinic acid can be produced from renewable resources by fermentation under consumption of carbon dioxide

� Succinic acid is a bifunctional molecule, that can be converted to:

� Monomers for high value polymers (polyamides, polyesters)

� Specialty chemicals and environmentally friendly solvents

No. 22

� Biorefinery is the concept of intelligent biomass utilization – not a single technology or plant layout

� Different processes and products will be suitable for different regional conditions

� Fraunhofer UMSICHT is working on succinic acid, biodiesel and bio-syngas processing

� Further development in key technologies (catalysis, biotechnology, downstream processing, process integration …) is necessary

� Agricultural production system and logistics have to be integrated

� New concepts should be examined by LCA
