Conversion of agro-cum-catering waste to renewable energy

Abstract

Non-conventional energy sources are an eco friendly choice to fulfill the growing energy requirements. The waste of food processing industries, pulp & paper industries, domestic and municipal waste, flowers waste, soiled and mutilated currency notes can be used for the energy generation. Flowers waste is anaerobically digested to produce the biogas. Electricity can be generated form the biogas with the help of an electricity generator. Soiled currency is shredded and briquettes are made which can be used for energy generation. Fruits and vegetable waste can be anaerobically digested in a digester with two gasholders to produce biogas. Slurry produced can be used as manure. The biogas produced from fruits and vegetable waste is about 2.5 times higher than biogas obtained from cattle dung.
