Bioorganic Waste from Municipal Solid Waste

The increasing global demand for energy, coupled with the urgent need to manage municipal solid waste sustainably. A significant portion of municipal solid waste comprises bioorganic waste, which holds massive potential as a renewable resource for energy recovery. Bioorganic waste is rich in organic compounds that can be efficiently converted for energy production; generally; it comprises food waste, paper, agricultural by-products, yard waste, and other biodegradable materials. Its high organic content and energy density make it a good source for energy recovery, offering a dual benefit of renewable energy production and waste reduction. This chapter outlines how bioorganic waste from municipal solid waste can be a valuable feedstock to produce energy with an emphasis on both thermochemical and biochemical processes. It examines the composition and characteristics of bioorganic waste by highlighting the preprocessing steps such as shredding, moisture reduction, and sorting for optimizing the conversion efficiency. Biochemical processes such as fermentation and anaerobic digestion are discussed, which harness microbial activity to break down the bioorganic waste into biofuels, biogas, and other valuable products. Furthermore, it discusses about thermochemical processes that include pyrolysis, gasification, and incineration for converting bioorganic waste into biochar, heat, and syngas. The chapter addresses the integration of these energy recovery systems within existing waste management infrastructures, promoting a circular economy model. The environmental benefits, including greenhouse gas mitigation, reduction in landfill dependency, and resource conservation, are thoroughly discussed.
