BIOMETHANATION OF KITCHEN WASTE

Abstract

Kitchen waste is the best alternative for biogas production in community level biogas plant. It is produce when bacteria degrade organic matter in the absence of air. Biogas contains around 55-65% methane, 30-40% of carbon dioxide. The calorific value of biogas appreciably high. 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 valuables, organic manure for farming and sustaining the soil fertility. Each of the biogas plant 2kg slurry capacity in batch system for all measurement. During the seperiod, the temperature, solar radiation and relative humidity have been measured. We have so analyzed the constituent of biogas, pH, volume and rate of biogas production at different level of temperature observation on daily basis. Here we also compare the rate of biogas production from kitchen waste with the other energy sources used for cooking purpose like LPG, Kerosene and coal.
