Design of Anaerobic Digester to Produce Biogas from Organic Waste

Abstract

Biogas is produced gas from biodegradable organic material in the absence of oxygen and consists of a large percentage of methane which is estimated at about 70%, the remaining is CO2 and other gases as small percentage depending on the type of biomass used. Biogas is clean and renewable energies source and can be used in cooking and generating electricity, the project also contributes to reducing global warming and improving the environment, particularly in rural areas. This research deals with the generation of biogas from organic waste which include livestock manure, kitchen waste can also be used (remains of rotten fruits and vegetables), and sewage. The anaerobic digestion of organic waste is processed at the anaerobic digester; this research designed of anaerobic digester produces 38.4 cubic meters of biogas per day and absorbs all organic waste from cattle farm at Assalaya sugar factory, which is estimated at about 960 kg per day.
