Comparison of Treatment Methodologies to Improve Anaerobic Biodegradability of the Organic Fraction of Municipal Solid Waste

The correct disposal of the organic part of municipal solid waste is becoming a critical concern around the world. The consequences of inappropriate disposal include degradation of the environment, public health risks, and a scarcity of dumping ground. Anaerobic digestion can help with embodied energy recovery from organic waste, as well as waste reduction. Among the parameters affecting digestion efficiency and cumulative methane production, the chemical makeup of the substrate is critical. In recent years, there has been a growing interest in treating substrate to improve digestive performance. This paper examines several treatment procedures, such as mechanical, thermal, chemical and biological for increasing methane yield from anaerobic digestion of municipal solid waste’s organic content. The correct disposal of the organic part of municipal solid waste is becoming a severe concern all over the world. To provide a proper understanding of the various processing methods, environmental pollution, treatment procedures, comparison of treatment methodology, and techno-economic assessment have all been presented.
