General definition Biorefinery:



A biorefinery is a facility that integrates biomass conversion processes and
equipment to produce fuels, power and chemicals from biomass. The biorefinery
concept is analogous to today‘s petroleum refineries, which produce multiple fuels
and products from petroleum
