BIOGAS PRODUCTION FROM POULTRY WASTE MODIFIED WITH SAWDUST
The high demand for energy as a result of the increase in population and the need to keep our environments clean makes research on biogas from wastes very necessary. The study was conducted to use poultry wastes mixed with sawdust to generate gases that can be used for cooking. The poultry waste was mixed with saw dust in the ratio 4:0, 4:1, 2:1 and 1:1 over a period of 4 weeks. The gases collected were subjected to laboratory analysis using Gas Chromatography of Perkin Elmer model. Methane yields of 3.45 x 10-3m3, 3.05 x 10-3m3, 2.03 x 10-3m3 and 1.00 x 10-3m3 were generated respectively. The more saw dust added the less gas of interest produced. Analysis of residue showed concentrations of N, P, and K in the residue are 0.847 %, 0.28 %, and 2.09 % respectively which implies materials that can be incorporated in soil amendment. Removing saw dust from the environment to generate gas reduces environmental pollution caused by burning.
