Biorefinery can be defined as a framework or a structure in which biomass is utilized optimally to produce multiple products and tries to be self-sustaining and not harmful to the environment.
A biorefinery is a facility that integrates biomass conversion processes and equipment to produce fuels, power, and value-added chemicals from biomass. Biorefinery is analogous to today’s petroleum refinery, which has multiple fuels and products from petroleum. By producing several products, a biorefinery takes advantage of the various components in biomass and their intermediates, maximizing the value derived from the biomass feedstock.
Global issues such as environmental problems and food security are currently of concern to all of us. Circular economy is a promising approach towards resolving these global issues. The production of bioenergy and biomaterials can sustain the energy–environment nexus as well as substitute the devoid of petroleum as the production feedstock, thereby contributing to a cleaner and low-carbon environment. In addition, the assimilation of waste into bioprocesses for the production of valuable products and metabolites leads towards a sustainable circular bioeconomy.
