Abstract
A report by the FOOD WASTE INDEX by UNEP estimates 931 millions of food waste was generated in 2019. The food waste alone causes 10% greenhouse gas emission .Demand for renewable energy has increased due to the depletion of fossil fuels .Anaerobic Digestion is a complicated biodegradable process involving a several bio chemical reactions in the absence of oxygen. In INDIA, the total potential of BIO-GAS production from various organic wastes is about 40,734 Mm3/year. The optimum studies were presented to improve the bio gas yield and production rate. This Review paper presents the overview of the parameters effecting and improving the biogas production from food waste through Anaerobic Digestion. The optimum value for HRT was found in the range of 25-30 days. The optimum value of OLR is around 2-3 gm VS/ L/day. The optimum temperature range is 25-30 degrees centigrade.
