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.
Description
ousehold organic waste encompasses all the biodegradable materials generated in
households as a result of daily activities. This type of waste primarily consists of
organic matter derived from food scraps, yard trimmings, and other biodegradable
materials. They are either discarded or slated for disposal (Saleh & Hassan, 2023). This
underutilized energy resource often undergoes decomposition in landfills and dumpsites,
resulting in the emission of greenhouse gases into the atmosphere (Ramprasad et al., 2022).
Primary sources of food waste generation comprise households, hotels, restaurants,
supermarkets, residential complexes, cafeterias, food processing plants, among others. Food
waste has the potential for recycling through processes such as anaerobic digestion (AD),
composting, and vermicomposting (Somashekar, Rinku, and Manzoor, 2014).
