Effectiveness of Biogas Production from Slaughter Waste using Two Mixing Ratios (Waste: Water Ratio of 1:1 and 1:2)

Sulemana Wumbei Sayibu, Ofosu Martin Ampadu


Biogas technology is widely used as a better alternative in the handling of waste in many societies in the world. This paper looks at the yield and the composition of biogas produced from slaughter waste using these two mixing ratios with a retention period of forty days. The study revealed that the 1:1 ratio gave 27.92 liters of Biogas per kilogram of waste, while the 1:2 gave 31.46 liters of Biogas per kilogram of waste. Analysis of the Biogas also revealed that for the 1:1 ratio, the composition of the Biogas was 67% methane, 30.7% carbon dioxide, 0.7% Hydrogen sulphide and 1.6% Oxygen. For the 1:2 ratio, the composition was 70.5% methane, 27.2% carbon dioxide, 0.6% Hydrogen sulphide and 1.7% Oxygen. The study therefore concludes that the 1:2 ratio was a better option for mixing waste and water when producing Biogas from slaughter waste.

Keywords: Biogas, Retention period, Slaughter waste, Methane, Carbon dioxide, Hydrogen sulphide, Oxygen.
