Slaughterhouse operations generate huge volumes of organic wastes which include dung, fats, blood,
animal trimmings, urine, and paunch contents. Slaughterhouse wastes should be carefully handled and
processed because are a potential source of bacterial, prion, viral, and parasitic pathogens, that can infect
humans and animals. Disposal methods include composting, rendering, anaerobic digestion (AD), alkaline
hydrolysis (AH), incineration and incineration. Slaughterhouse waste especially that with high fat and
protein of slaughterhouse is excellent substrate for anaerobic digestion processes that leads to both disposal, nutrient recycling, and in methane generation. Slaughterhouse waste can pollute air, soil, and water if disposed of untreated or poorly managed. This study demonstrates the potential of abattoir waste in the energy transition to renewable energy and low carbon electricity. The performance of operating
slaughterhouse was used as a basis feasibility assessment. The composition of slaughterhouse waste was
presented, and production output estimated under current and optimal conditions. Slaughterhouses can be
meet their own internal energy use and export excess as biogas, biomethane or electricity. This will earn
extra revenue, mitigate against greenhouse gas emissions by displacing fossil fuel sources and solve the
challenge of waste treatment and disposal.
