Feasibility study on electricity generation from poultry litter based biogas in Bangladesh

Renewable Energy (RE) technology holds great potentials as alternatives to conventional energy generation to reduce the large deficit in electricity supply that currently exists in Bangladesh. Biogas plants are being considered as a promising RE source to supply electricity in a localized area. Traditional biogas plants have been based on cow manure from dairy farms. Recently biogas plants are being deployed based on poultry waste since the calorific value of poultry waste is higher than that of cow manure and also due to the existence of large number of moderate to big size poultry farms in this country. This paper presents studies on the amount of available electrical energy and also the economic feasibility of biogas plants deployed in poultry farms. The results presented in this paper shows that 60 kWh of electrical energy can be generated daily from a farm size of 6000 birds and the cost of investment can be recovered within a period of approximately 4 to 6 years.
