Abstract
Biogas extraction from human excreta and kitchen waste was investigated. A biogas production system was developed locally, a tank filled with human feces and kitchen waste. Anaerobic treatment of excreta and kitchen waste was able to produce biogas which is a potential renewable energy source. Sixteen groups of sample were first produced containing different percentage composition the materials. The biogas produced, the PH Value, temperature and moisture content of the sixteen different samples mix were analyzed. All of the samples experienced its peak in day 14, which was in thermophilic condition. Taguchi method of design of experiment was used to determine the optimum design parameters, the levels used are, Temperature (29, 38, 48, 57 oC), PH value (7.0, 7.3, 7.6 7.9), and moisture content (45, 50, 55, 60. %). The L16 (4^3) full factorial design with a mixed orthogonal array was selected to conduct the experiments. Biogas produced was used as response while PH Scale, moisture content and temperature was used as control factors. Result showed that the optimum setting for the methane gas produced is: temperature of 38, PH value 7.0 and moisture content of 60 percent. Analysis of variance (ANOVA) was used to confirm the experiment that the most significant factor for the biogas produced is the temperature, as depicted in their signal to noise ratio using Minitab 2020 software. Sensitivity test was carried out for the biogas yield between the Taguchi method, and the Regression model. Confirmation test was carried out using the optimum test parameters and the regression model and experimental results showed a deviation of 6.5% which is agreeable
