Biogas Production from Different Waste Matireals in India

Abstract

The requirement of liveliness has been better than before over the years as the sequence by rising of the world population and development of global industries especially for food and feed. In this article we discuss about biogas production from different raw materials and its application in agriculture. Biogas is produced by the anaerobic digestion or fermentation of biodegradable materials such as biomass, manure, sewage, municipal, animal waste, plant material and crops. Biogas composition includes 50%-60% methane and 25%-45% CO_2. Anaerobic process basically involve the decomposition of organic and inorganic matter in the absence of oxygen and at the end of this process nutrient rich digested slurry is produce which is use as a biofertilizer.  The extent of adaptation of biogas technology across the worlds is also briefly reviewed in this article. The need of a national policy is imperative to bring this technology at farmer's doorstep
