Biogas technology provides alternative source of energy mainly from organic wastes. It is produced when bacteria degrade organic matter in the absence of air. Biogas contains around 55-65% of methane, 30-40% of carbon dioxide and small quantities of hydrogen, Nitrogen, Carbon monoxide, Oxygen and Hydrogensulphide. The calorific value of biogas is appreciably high around 4700 kcal or 20 MJ; at around 55% methane content.
The systems that are used to create bio-energy can greatly contribute to reducing greenhouse gases as they have the possibility of reducing the need to use fossil fuels. By providing a non-polluting energy source which is also renewable, the earth is being kept clean of harmful emissions. A mini biogas plant with a capacity of 20Cft is in operation in the college mess. The raw materials for bio gas production are: leftovers of food items, vegetable peelings and cow dung and water etc. The gas produced will be used in the college mess kitchen for cooking of items on small scale.
