THE PRODUCTION OF BIOGAS USING COW DUNG AND FOOD WASTE

THE PRODUCTION OF BIOGAS USING COW DUNG AND FOOD WASTE

Abstract

In Nigeria, the scarcity of petroleum supply particularly kerosene has become a national concern. Biogas technology has gained national interest. This research was to generate biogas using cow dung and food wastes. Food wastes (corn cobs and plantain peels at the ratio of 1;1) were collected from the Abia State Polytechniccanteen and cow dung from Aba North LGA slaughter house as feedstock for the anaerobic digestion system to produce biogas energy. This design was to combined feedstock with high caloric content and anaerobic microbes. The proximate composition revealed that the two feedstock contained energy yielding nutrients but at varying concentrations. The study revealed that the pH decreased possibly as the bacteria produce acids in the digester. The decrease was more observed in the cow slurry experiment as it recorded acidic at the 4^th day than the combined waste slurry which recorded acidic at 12^th days. The data showed the volume of biogas production in respect of number of days under the various slurry. It can be deduced from the data that gas production increased in the earlier days of the experiments and then started decreasing as acid concentration increases as indicated by the decrease in pH. This observation was more pronounced in combined waste slurry than the cow dung slurry. The result supported the observation that acid concentration greatly affects the biogas production. Thus the combined waste slurry produces more gas (30.58ml) than cow dung slurry (19.20ml) as food wastes contain more nutrients than the dung. It has been demonstrated by this study that by using combine feedstock (cow dung and food wastes) the efficiency of biogas generation can be increased.
