The demand, high costs and health implications of using energy derived from
hydrocarbon compound have necessitated the continuous search for
alternative source of energy. Cow dung as a renewable source of energy
supply has been proven to be very efficient. This study investigated the
production of biogas using cow dung from cow field near the polytechnic. A
2ml/g of the cow dung was used in this study. The digestion was carried out in
a 10 L anaerobic digester at a temperature of 250C to 300C and uncontrolled
pH for a period of 1 month. About 23 cm3 of biogas was produced on the
22nd day. Thus biogas production from cow dung is a good and cheap
alternative source of energy. The use of biogas will not only serve as a source
of fuel but will also help in the management of waste. The biomass generated
after digestion can be used both as animal feed and to improve soil fertility. It
is therefore recommended that large scale production of biogas from wastes
should be undertaken by all as the wastes around you today can become your
wealth tomorrow
