Energy supply and utilization is one of the economic indices of regional development and standard of living. Energy availability in the rural areas of Nigeria is fast becoming a great challenge with the high cost of cooking gas and kerosene and environmental problems associated with firewood. The paper demonstrated the use of a pilot model study (floating drum plant) of bio-decomposition of animal waste (cattle dung and fodder) in an anaerobic condition (single batch system) to generate methane for domestic cooking. This is a unique way of waste management with additional values of energy accessibility, reliability, quality, cost and benefits including environmental and social aspects. Method involved the pre-treatment of the substrate and its inoculation. Material compositions were batched by weight. Gas produced was monitored for 10 times at 3 days interval effective from the fifth day of retention. Efficiency increased to peak at the 11th day (32.8% of the total cumulative, TC) and reduced to 1.2% TC at the 22nd day.
