| Abstract | ||
| Nigeria is presently grappling with a substantial energy crisis due fuel subsidy removal; however, many Households possesses organic waste which has notable potential for biogas energy production owing to its high biodegradability and calorific value, thereby reducing the dependence on fossil fuels. An evaluation of the physical and chemical properties of household organic waste was conducted. The produced Biogas was collected utilizing a compressor and subsequently subjected to Gas Chromatography with Headspace for characterization. The findings from the physical and chemical analysis of the household waste include a moisture content of 59.2%, total solids at 40.8%, volatile solids at 77.3%, and carbon content at 42.9%. The biogas characterization reveals its composition, comprising 63% methane (CH4), 31% carbon dioxide (CO2), and 1% hydrogen sulfide (H2S), with a calorific value of 24.10 MJ/m3 while the byproduct of the anaerobic process, known as digestate, represents a valuable nutrient source essential for agricultural fertilization. This study proposes that every household in Nigeria has the potential to serve as a supplier of biogas energy and bio-fertilizer by harnessing their organic waste | ||
