Within a future sustainable society, biomass is expected to become one of the major renewable resources for the production of both food, feed, materials, chemicals, fuels, power and/or heat. The development and implementation of biorefinery processes – i.e. the sustainable processing of biomass into a spectrum of marketable products and energy – is an absolute necessity to meet the vision, i.e. to use the available biomass as efficiently as possible, and with the lowest environmental impact. The goal of this Status Report Biorefinery 2007 is to present an overview of the current status and developments in the biorefinery area both from a national (Dutch), European and global point of view. The description of the current status includes: an overview of both existing biorefinery concepts and concepts that still have to be developed (a.o. Green, Whole Crop, Ligno Cellulosic Feedstock, Two Platform, Thermo Chemical, and Marine Biorefineries)
