Abstract. In this paper, experimental research was accompanied to examine the yield of biogas from kitchen waste (KW), cow dung (CD) and chicken manure (CM) through using anaerobic co-digestion process. The experimental protocol was defined to detect the consequence of organic loading rate (OLR), temperature, and pH on the effectiveness of the yield of biogas. A transportable biogas reactor was invented for effective biogas manufacture which comprises an agitator and a heating system. The CD, KW and CM co-digestion ratios are 1:2:0, 1:2:2, 1:2:4 and 1:2:6 separately at loading rates of 360, 367.5 338.25 and 427.5 g/l were studied. The result presented that the uppermost degradation amount of 3.98 ml/g obtained from the loading rate of 367.5 g/l. Further, KW was co-digested at different temperatures 25, 35, 40, 45, and 50 °C respectively in same loading rate of 367.5 gm/l. The result showed that the highest rate of degradation 7.00 g/l was investigated at temperature 37 °C. Then KW was co-digested at different pH. Mono-basic phosphate (NaH2PO4) and di-basic phosphates (Na2HPO4) were used to yield buffer result for maintaining diverse pH level. Five diverse pH levels are 6.8, 7.0, 7.2, 7.4, and 7.6. The result showed that the highest degradation rate of 8.6 ml/g obtained from pH 7.4. The result from this study proved that optimum loading rate 367.5 g/l, temperature 36–38 °C, and pH 7.40 is more effective for biogas production.
