Abstract
Access to clean energy is a global challenge in developing countries. Global cities experience a burden of waste management due to higher generation rates. The study investigated the impact of combining Municipal food waste (MFW) and poultry manure (PM) on substrate physicochemical properties and biogas yield. MFW: PM ratio by weight of 5:1, 4:2, 3:3, 2:4 and 1:5 was used. Results indicate that MFW enhanced substrates’ total solids (%TS) and volatile solids (%VS), while PM enhanced pH and moisture content (%MC). An optimal MFW and PM ratio of 5:1 gave the substrate with 72% MC, 96.7% VS, and pH of 6.25 ± 3.1. Volume yield from MFW and PM mixture ranged from 2.71 ± 0.03–49.91 ± 0.28 L. Methane content and flammability ranged from 38 ± 3.42–58.9 ± 5.22% and 34.10 ± 3.28%–72.04 ± 14.0%, respectively. Co-digestion gave higher yield above 98%, compared to mono-digestion. The 5:1 ratio yielded the most significant volume of biogas with methane content of 58.9 ± 5.22% and lower explosive limit of 72.04 ± 19.47%. The 5:1 ratio can be adopted for biogas production and clean energy for cooking with a multiplier effect on MFW and PM management. Further research on blending PM with agricultural residues is recommended to improve biogas production by examining its impact on substrate pH and %MC.
