Abstract : Waste management has become a major environmental concern due to the increasing accumulation of organic waste and its associated impacts on environmental quality and public health. Open dumping and uncontrolled burning of waste contribute significantly to greenhouse gas emissions and environmental degradation. This study investigated the production of biogas from cow dung using a laboratory-scale anaerobic digester. A 20 L capacity prototype biogas digester was designed, fabricated, and tested under batch operating conditions. Fresh cow dung was mixed with water in a ratio of 1:2 and supplemented with Moringa oleifera leaves as a biological starter to enhance microbial activity. The digestion process was monitored for 21 days, during which temperature, pH, gas production, and gas composition were evaluated. Results showed that biogas production commenced on the third day of digestion and increased steadily until peak production was attained.

Keywords : Biogas, Anaerobic Digestion, Cow Dung, Renewable Energy, Waste Management, Methane Production.
