COMPARATIVE STUDY ON BIOGAS PRODUCTION FROM COW DUNG, FOOD WASTE AND ORGANIC WASTES

Anaerobic digestion is one of the ecofriendly methods to treat and dispose the biodegradable wastes and has more advantages when compared to any other waste treatment methods. Biogas production and composting of slurry from the biogas plant is one of the methods to reduce volume of waste (zero waste discharge) and maximum energy recovery from the organic wastes is possible. In this study the production potential of biogas from bio degradable organic wastes such as food waste, cow dung and fresh organic wastes under the same operating condition of room temperature between 28ºC to 32ºCare compared. A pilot plant of 0.3 cubic meter gas holding capacity is used as digester.
