Abstract:

Sharda University is developing and the demand for cooking gas is increasing, the university still relies on gas from the Indraprastha Gas limited to meet its cooking requirements. It spends much for buying cooking gas, while the use of fuels such as gasoline and diesels in our generators contributes to the increase in the greenhouse gases; the demand for biogas digester arises as a result of huge amount of food waste produced per day and its potential. It was recorded that biogas digesters that uses kitchen waste are 800 times efficient than conventional biogas systems, therefore a 4.8 m3 capacity of biogas digester that would digest 86 kg of daily food waste to 25.8 m3of biogas was successfully designed, constructed, tested and analysed to reduce over dependence on CNG for cooking in the three Mandela hostel messes of the University. After testing the digester for 40 days, its performance was found low; this could be due to the leakages from the gas storage chamber resulting from the use of bricks instead of stones in its fabrication during construction process. High amount of carbohydrate waste (85 %) instead of vegetables could hinder the digester performance. The biogas produced is considered as an ideal gas, and the ideal gas equation was therefore used to find the volume of biogas produced. 7.5108 L was the maximum volume produced on 27th day at 35oC. The maximum temperature recorded during the process was 42oC. The amount of food waste produced and the corresponding gas consumption by each mess of the university are discussed.
