Abstract:
This study was carried out to assess the energy recovery potential from solid organic by-products of a poultry slaughtering facilityand to explore the potential of an energy self-sufficient industry. There are several processes to convert organic material to energy; the technology of interest in this study was biogas transformation, the biological conversion of degradable organic material into methane. The scenario was confined to a full scale poultry slaughtering facility processing 150,000heads weekly and having a Specific Energy Consumption (SEC) of 3096MJ t-1 of dress carcass weight. The methane potential of chicken manure, soft offal, dissolved air flotation sludge as well as a mixed waste stream (combination of the soft offal and sludge) was determined through a series of biochemical methane potential assays under mesophilic conditions. The methane potential of the chracterised waste streams ranged from 251.5-694.6mlCH4 gVS-1. The highest methane yield achieved was from the mixed waste stream, 594.6mlCH4 gVS-1or 206.68m3 biogas t-1 of wet waste with a 66% methane content. The technical analysis explored the combustion of the potential raw biogas production from the digestion of 5680t of the mixed waste in a combined heat and power unit with anoverall efficiency of 86%. The biogas generation and subsequent energy recovery could potentially subsidies 57.5% (43.4% electricity and 82.6% thermal) of the SEC of the poultry slaughterhouse sampled.
