The poultry industry in Nigeria has gone through series of developmental stages in the last forty years. One of the major problems is the accumulation of large amount of wastes, especially manures and litters, generated by intensive production of poultry. Poultry industry is also facing energy related problems to remain in business and have their break-evens. This study evaluated the engineering economic viability of the process of biogas generation from these poultry droppings. The study was carried out using techno-economics analysis methodologies adapted from National Advanced Biofuels Consortium (NABC). A set of questionnaire was also administered on one hundred and eighty (180) poultry farmers in all the Southwestern States of Nigeria using snowball sampling technique. Data were analyzed using engineering economic techniques and descriptive statistics. The engineering economic analysis of the biogas production revealed that the Net Present Value (NPV) of poultry farms having bird capacities of 1,000; 2,000; 3,000; 4,000 and 5,000 were all positives $848; $4386; $7,857; $12,050 and $15,176 respectively, while only the NPV of 500 birds’ capacity poultry farm was negative -$411. Also, biogas generated from these poultry capacities 500 to 5,000 birds can amount to $1,502 to $7,562 and the accumulated slurry from these poultry capacities can generate $10 to $100. In conclusion, biogas production is technologically and economically viable for a poultry farm with above 1,000 birds.
