Design of biogas digester for effective utilization of kitchen waste from hostel mess

The uses of renewable energy sources are becoming very essential due to the limited reserves of fossil fuels. Biogas is a valuable renewable energy source containing 55% methane and a sustainable mode of waste disposal. This research work focusses on the biogas production from the food waste collected from a hostel mess. Kitchen waste is one of the wastes having high calorific value and can be used for solving the problem of increased demand of fuel and waste disposal. The use of biogas using kitchen waste as feedstock can help solving the problem of energy scarcity and at the same time; allow safe disposal of kitchen waste which is often unscientifically dumped or discarded. It maximizes the reduction of food waste to the ground. This biogas plant will provide biogas for cooking purpose and also manure for vegetation purpose. The kitchen waste is obtained up to 27.5 per kg/day may be produce gas up to 6.54 m3/day within 30 days of retention period.
