Assessment of Biogas Production from Anaerobic Digestion of Cassava Peelings, Poultry Dropings & Beans Wastes

The negative impact of the increased use of fossil fuels for energy generation and consumption has reached a global dimension and can no longer be over looked. All efforts are now being geared towards an alternative source of energy, renewable in nature and more environmental friendly in use. This study investigates the production of biogas ? a renewable energy from the anaerobic digestion of three different types of biodegradable wastes (Cassava peelings and poultry droppings, Beans waste and poultry droppings, Cassava peelings and beans wastes) as an alternative to fossil fuels for energy consumption. The study was carried out using a 0.1m3 capacity biogas digester constructed to investigate the anaerobic digestion in generating biogas. The experiment was batch operated and daily gas yield from the plant was monitored for 30 days. During this period, temperature, pressure and PH of the slurry was monitored. Cassava peelings and poultry dropping generated the highest maximum biogas of 0.035m2/kg/day at a PH value of 7.35 on the 19th day. This was followed by poultry droppings and beans mixture. Cassava peelings and beans waste had the least volume of biogas. This treatise assets that biogas is not only a renewable energy source but has a dual function of waste management in the course of its production.
