Biorefinery

Definition

A biorefinery is a facility that integrates biomass conversion processes and equipment to produce fuels, power, and value-added chemicals from biomass. It serves as a sustainable alternative to fossil fuel refineries, aiming to maximize the use of renewable resources while minimizing waste and environmental impact. Biorefineries can utilize various feedstocks, including agricultural residues, forestry products, and organic waste, contributing to a circular economy.
