It may be categorized according to its origin (domestic, 2 LITERATURE REVIEW industrial, commercial, construction or institutional); according to its contents (organic material, glass, metal, Kumar et al., (2004) investigated the reactivity of plastic paper etc); or according to hazard potential methane. They concluded that it has more than 20 (toxic, non-toxin, flammable, radioactive, infectious times the global warming potential of carbon dioxide etc). Management of solid waste reduces or eliminates and that the concentration of it in the atmosphere is adverse impacts on the environment and human health increasing with one to two per cent per year. The and supports economic development and improved article continues by highlighting that about 3 to 19% of quality of life. A number of processes are involved in anthropogenic sources of methane originate from effectively managing waste for a municipality. These landfills include monitoring, collection, transport, processing, recycling and disposal. Murphy, McKeog, and Kiely (2004) completed a study in Ireland analyzing the usages of biogas and bio Key Words: Municipal, solid, waste, Municipal Solid Waste management, and handling, fuels. This study provides a detailed summary of comparisons with other fuel sources with regards to its effect on the environment, finical dependence, and functioning of the plant. One of the conclusions the 1.INTRODUCTION study found was a greater economic advantage with utilizing bio fuels for transport rather than power Anaerobic digestion like composting uses biological production; however, power generation was more processes to decompose organic waste. However, permanent and has less maintenance demands where composting can use a variety of microbes and Thomsen et al. (2004) found that increasing oxygen must have air, anaerobic digestion uses bacteria and an pressure during wet oxidation on the digested bio oxygen free environment to decompose the waste. waste increased the total amount of methane yield. Aerobic respiration, typical of composting, results in Specifically, the yield which is normally 50 to 60% the formation of Carbon dioxide and water. While the increased by 35 to 40% demonstrating the increased anaerobic respiration results in the formation of ability to retrieve methane to produce economic Carbon Dioxide and methane. In addition to generating benefits. the humus which is used as a soil enhancer, Anaerobic Digestion is also used as a method of producing biogas which can be used to generate electricity. Optimal conditions for the process require nutrients such as nitrogen, phosphorous and potassium, it requires that Š 2016, IRJET
