Conventional biogas has considerably low output methane gas for a given organic input. Considering the need for efficient biogas plant, SOWMS （solid organic waste managing system） has been designed and implemented on a trial basis by constructing community bin at ward number 4 of Gothatar VDC, Nepal. When composition of output biogas from the SOWMS was tested for five times, at different days, the average composition of gas was 55% methane and 35% carbon dioxide. The gas produced from 1 kg of waste is calculated to be 45 liters and pH value of slurry was found to be 7.8. These values indicate that designed system has good performance and that it can be optimized in the future research. Finally, this research work has some social implications that can have potential impact to uplift the society.展开更多
