ABSTRACT

Biogas is a renewable source of energy which is developed to fulfill the energy needs of the society. This research aims to design a minisized biogas plant which can be used effectively to produce the alternative energy, and also to examine the difference quality of biogas which is produced from slurry. Biogas production requires Anaerobic digestion. Project wasto Create an Organic Processing Facility to create biogas which will be more cost effective, eco-friendly, generate a high-quality renewable fuel, and reduce carbon dioxide & methane emissions. Kitchen waste is the best alternative for biogas production in a community level biogas plant. 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. The calorific value of biogas is appreciably high (around 4700 kcal or 20 MJ at around 55% methane content). The gas can effectively be utilized for generation of power through a biogas-based power-generation system after dewatering and cleaning of the gas. In addition, the slurry produced in the process provides valuable organic manure for farming and sustaining the soil fertility. Here we also compare the rate of biogas production from kitchen waste with the other energy sources used for cooking purposes like LPG, Kerosene and Coal
