Anaerobic Digestion (AD) is a technology used for the treatment of organic waste for biogas production in the absence of oxygen (Budyono et al (2001), Zehnder (1972). Biogas is a biofuel produced from the anaerobic fermentation of carbohydrates in plant material or waste (eg food peelings or manure) by bacteria . Let us have a deeper understanding of the generation of biogas from poultry waste: Working of a Poultry Waste Biogas Plant It has been demonstrated by this study that by using combine feedstock (cow dung and food wastes) the efficiency of biogas generation can be increased. Anaerobic digestion is a microbial process for production of biogas, which consists of primarily methane (CH4) & carbon dioxide (CO2). Technol. The volume of Biogas generated was less compared with the past studies conducted under sunlight (out door).

The use of biogas will not only serve as a source of fuel but will also help in the management of waste. cow-sheep manure at low temperature (291-298) K. The methane yields obtained in the mixture experiments were in the range 0.07-0.14 m3/kg added, with a methane concentration in the gas of between 47% and 55% [7]. 'tems based on cow dung and human waste. However, due to instabilities in set-up and operation, a large number of factors affect biogas production efficiency biogas production from cow dung and food waste. The time required for sonication was calculated as a function of the volume of feed and total solids. What is biogas? This research shows that biogas can be produced from cow dung through anaerobic digestion. Different ratios of cow dung and cafeteria wastes were taken in different digesters as follows. It also indicates that blending paper was te with cow dung or any other animal waste wil l give sustained. Food wastes (corn cobs and plantain peels at the ratio of 1;1) were collected from the Abia State Polytechnic canteen and cow dung from Aba North LGA slaughter house as feedstock for the anaerobic digestion system to produce biogas energy. The percentage of volatile solids was 52.5, 86.3 and 18.9 for cow dung, food waste and digested slurry respectively. In this experimental work, an equal ratio of 2.5kg kitchen waste and 2.5kg water with small amount (1.75kg) of cow dung was weighted. Production of biogas is n the ele are entrations.

The research exposed further that cow dung as animal waste has large possibilities for production of biogas. The pH value of the cow dung and food waste was initially measured and adjusted to nearer to neutral and gradually increased to acidic and again it got stabilised to the neutral pH which favoured the production of biogas. As the world divests from fossil fuels, new and varied energy sources will be necessary to satisfy the energy needs of the world and biogas can help. Biogas digesters are most efficient when working on organic waste with a neutral pH. What is the need for biogas production? Biogas can be used as energy source and also for numerous purposes.
