FLEXFUEL2 The Green Biorefinery The idea behind a Green Biorefinery is that all crops and biomass resources are utilised as feedstocks in stepwise treatments. Basically with as low energy input as possibly by applying biotechnological methods; enzymes, fermentation, separation, and purification for various products. The concept produces a portfolio that is capable of replacing fossil fuel refined products. [Source: P. Kiel and J. B. Holm-Nielsen, University of Southern Denmark, 1994]

FLEXFUEL4 Introduction to FLEXFUEL The project will demonstrate use of biofuels from well to wheel. It demonstrates the hitherto cheapest production of ethanol by using organic material of which a large part is classified as waste. It demonstrates flexible change to fuels, and it has a large European potential. Therefore it has extremely high relevance to the objectives of the Specific Programme and the Work Programme.

FLEXFUEL22 Conclusion Biorefinery is integration of various robust treatment technologies for conversion of complex biomasses into various products for energy and industrial use. FLEXFUEL is an EU full scale demonstration plant for combining the production of bioethanol and biogas in a flexible way, where by-products from the main production in the first process plays a major role as a feedstock in the second process. Optimisation of biotechnological treatment processes with as low process energy input as possible and scale flexibility will be demonstrated.
