A review paper on aerobic and anaerobic biodegradation

Biodegradation, whether aerobic or anaerobic, is a method for cleaving large molecules from a mosaic of chemicals and materials in a series of steps, with some of the smaller molecules being valorized as a pollution abatement strategy and a source of energy through biogas generation. Biogas may be made from virtually any kind of biomass, including main agricultural sectors and different organic waste streams, which can be used as a sustainable energy source. Animal dung that has not been properly handled or managed is a significant cause of pollution in the air and water. Some of the most serious concerns include nutrient leakage, particularly of nitrogen and phosphorus, as well as ammonia evaporation and microbial contamination. the animal manufacturing is responsible for 18 percent of total CO2 equivalent emissions and 37 percent of atmospheric methane, which has 23 times the global temperature potential of CO2. Furthermore, the global animal production sector is responsible for 65 percent of human activity nitrous oxide and 64 percent of anthropogenic ammonia emissions.
