Biomass processing involves converting organic materials, such as plant and animal waste, into usable energy or products. This process can include methods like combustion, fermentation, and anaerobic digestion, which break down the biomass to release energy or produce biofuels like ethanol and biodiesel. The goal of biomass processing is to create renewable energy sources that can reduce reliance on fossil fuels and lower greenhouse gas emissions. By utilizing materials that would otherwise go to waste, biomass processing contributes to sustainable practices and helps in managing waste effectively.
