Abstract
Abstract The study was carried out to produce biogas from cow dung and poultry wastes. The study was also carried out to determine the heat efficiency of each of the biogas produced. Nineteen litre bio-digesters and gas collection systems were fabricated using locally available materials. The respective organic materials used for the feed stock were collected locally. The slurry was prepared from each of the wastes by mixing with five litres of clean water. Water dispenser bottles were used to digest slurries of cow dung and poultry wastes. The wastes were digested and analyzed in accordance with standard methods. The physico-chemical parameters and gas yields were monitored daily. The average digester temperatures during the study were within the mesophillic range (24-37°C) which is best for methanogens. The pH values were within the optimal range 7.0 and 7.5. The total gas yields were 826m1 and 286.3m1 for cow dung and poultry wastes. A domestic heating test was carried out for the two substrates digested using the biogas produced to raise 1 litre of water to boiling point (100°C). The time expended was recorded in minutes as follows- 7.42 mins,7.46mins for cow dung and poultry wastes using a stop watch. The experimental procedure lasted for 14 days. The study revealed that cow dung had the highest heat efficiency and cooking rate while Poultry wastes had the lowest heat efficiency.
