Abstract

Poultry industry is growing at a rapid pace as a result of increased demand of meat product globally. The sector also generates massive amount of organic waste, which consists of protein, uric acid, ammonia as well as other nitrogen constituents. The waste is harmful to humans, animals and the environment if left uncontrolled in the open ground. The waste can be useful, if treated anaerobically to produce biogas. Countries like USA, Germany, etc. the waste is digested in an anaerobic digester to generate biogas, which is being utilized for heat application and generating electricity. (German Society for Sustainable Biogas and Bioenergy Utilization, 2009). However, impurities of H2S, CO2 and moisture contents in the biogas reduces the quality of the gas generated and hence the efficiency of electricity generation and the life of the engine/heating device (Nallamothu, et al., 2013). The anaerobic digester includes: plug flow, floating drum and the fixed dome digester. They used in the treatment of poultry waste to recover useful resources such as biogas. The design of a fixed dome digester will be considered, providing a clear description of the structures, constructions and used building materials. The techno-economic feasibility will cover the technical and financial aspects involved in designing the fixed dome digester. The study will encourage the public in constructing fixed dome digester for biogas production to meet their need for energy.
