Anaerobic digestion has been considered as waste-to-energy technology, and is widely used in the treatment of different organic wastes, for example: organic fraction of municipal solid waste, sewage sludge, food waste, animal manure, etc. Anaerobic treatment comprises of decomposition of organic material in the absence of free oxygen and production of methane, carbon dioxide, ammonia and traces of other gases and organic acids of low molecular weight. Recently, large volume of goat dung generated from feedlot farming increases annually, most of which are disposed into landfills or are applied to the land without treatment. Anaerobic digestion provides an alternative option for energy recovery and waste treatment. This experiment was performed at National Centre for Energy Research and Development, University of Nigeria, Nsukka. The maximum atmospheric temperature recorded for the first four days of the experiment are 27⁰C, 29⁰C, 28⁰C and 30⁰C respectively. The highest volume of biogas recorded in the experiment was 7.1 litres. The moisture content of the dung was 15%.
