The Czech BIORAF project employs the techniques of green chemistry for biomass utilization to high added-value products and energy sources. Refining it results in food supplements, fodders and fertilizers, new-generation biofuels and energy from the biomass of microbial, plant or animal origin. Biorefining is a unique approach for a new sustainable substitution of fossil fuels minimizing an adverse effect on the environment while exploiting the whole volume of biomass. and Pavel Topka.
