DESIGN OF FIXED DOME DOMESTIC BIO DIGESTER FOR DEGRADATION OF KITCHEN WASTE USING MESOPHILIC & THERMOPHILIC REACTIONS (ANAEROBIC)

Solid waste generation rates are rising fast with a pace of 11 million tons per day on a worldwide scenario. Therefore, there is a need to solve this problem by segregating and degrading the waste using various technological advancements. Biogas technology can alleviate several problems mainly energy crisis in rural areas, low agriculture yield and sanitation affairs. The main purpose of the study is to outline conditions under which biodigesters would be feasible to society and help to decipher the mentioned problems. It focuses on solving waste management at household level and production of biogas as an alternative source of energy. Wet organic waste from homes is crushed and mixed with water and fed to the fixed dome biodigester which will produce 0.4 cubic meter of gas per day. As the domestic biodigester operates in the absence of oxygen in sealed tanks, it reduces problems related to odors. The digester can be fitted with solar panels or electric heaters, depending upon the climatic conditions. The main agenda is designing and fabricating such a biodigester that is economical, compact and functions effectively.
