Abstract
Solid wastes are generated and dump indiscriminately in Nigeria due to poor implementation of standards, thus causing environmental and public health hazards. Nigeria generates more than 32 million tons of solid waste annually, out of which only 20-30% is collected and disposed in an open dump site. Different researchers have reported that organic waste fraction of solid waste generated in Nigeria has the highest percentage which is over 50%. However, this fraction of organic waste is yet to be properly utilized for biogas production. This research work is focused on the performance evaluation of biogas potential yields from co-digestion of kitchen wastes and water hyacinth. A 0.030m3 anaerobic mild steel digester was fabricated and used to digest the composition of water hyacinth and kitchen wastes. The experiment was conducted under mesophilic temperature range and a pH range of 6.0-7.4. The results obtained show that a cumulative biogas yield of 0.0499m3 was obtained from 30kg of substrates composition of kitchen waste and water hyacinth. Besides, optimum biogas yields were obtained at optimum mesophilic temperature.
