Anaerobic Digestion: Addressing the Problem of Food Waste by Converting it into Biogas

In some parts of rural India, biogas production is a crucial energy source. The statistics show that it is equivalent to 5% of total LPG production. It is a promising renewable source of energy. The resources required for biogas production are easily available in rural and urban areas. Biogas is mostly generated by using degradable wastes such as animal dung, agro-waste, industrial waste, poultry waste, vegetable, and food waste (FW), in addition to a combination of a majority of these wastes. The boost in the production of biogas can be helpful in reducing the load on traditional energy resources. Biogas production can be boosted by using various techniques, such as adding different additives, different pretreatment methods, and using the appropriate co-digestion technique. The present article discusses how biogas production can be boosted by using various techniques.
