| Abstract | As the effects of climate change are felt, the country needs to transition to sustainable energy sources. With this goal, the experiment studied the potential of buffalo manure and market fruit and vegetable wastes in biogas production through anaerobic co-digestion, as the combination of these substrates has yet to be explored, and the Philippines is home to millions of buffalo. The study examined how moisture content, the initial pH of the substrate mixture, and buffalo manure content affect the methane production of the different proportions of feedstocks. The results of the experiments showed that the methane generated after 15 days was highest at 64.5 ml/gVS in the mixture of 50% buffalo manure, 94% initial moisture content, and initial pH of 7. A statistical model relating the three parameter (buffalo manure content, initial moisture content and initial pH of the substrate mixture) to methane yield (ml/gVS) was generated. It can be used to estimate the latter given the values of the the said three process parameters. The hydrolysis rate constant, k, values of samples with 25, 50, and 75% buffalo manure content are 0.0440, 0.0297, and 0.0178 day-1, respectively. The ammonium level of all mixtures exceeded 600 mg/l in specific periods which indicates that ammonium inhibits the methanogenesis process, which may have inhibited methane generation. The data gathered from this research can be used as basis for designing larger scale methane production from buffalo manure and fruits and vegetables wastes. The results of this study can be used for encouraging the use of anaerobic co-digestion of the waste to produce methane as clean fuel and as strategy for decarbonization. |
