Biorefining is the process of "building" multiple products from biomass as a feedstock or raw material much like a petroleum refinery that is currently in use.
[1] The process of biorefining can be characterized as the sustainable processing of biomass, which eventually yields:[2] A biorefinery is a facility like a petroleum refinery that comprises the various process steps or unit operations and related equipment to produce various bioproducts including fuels, power, materials and chemicals from biomass.
Industrial biorefineries have been identified as the most promising route to the creation of a new domestic biobased industry producing entire spectrum of bioproducts or bio-based products.
Biomass has various components such as lignin, cellulose, hemicelluloses, extractives, etc.
The various bioproducts can include fiber, fuels, chemicals, plastics etc.
