Solid wastes need to be characterized by sources, generation rates, types of wastes produced and composition in order to monitor and control prevailing waste management systems while improving the existing system. As per the conservative estimation done by the World Bank in 1999, the municipal solid waste (MSW) from urban areas of Asia has gone up from 760,000 tons/day in 1999 to 1.8 million tons/day in 2025. With the increasing income in the countries of Asia, the solid waste management would be more challenging in the coming days in the continent [1]. MSW generation is over-riding the population growth in Indian mega- cities [2]. Municipal solid waste (MSW) generally includes degradable (paper, textiles, food waste, straw and yard waste), partially degradable (wood, disposable napkins and sludge) and non-degradable materials (leather, plastics, rubbers, metals, glass, ash from fuel burning like coal, briquettes or woods, dust and electronic waste). Generally MSW is managed as collection from streets and disposal at landfills. Anaerobic decomposition of MSW in landfills generates about 60% methane (CH4) and 40% carbon dioxide (CO2) together with other trace gases [3]. This percentage differs spatially due to waste composition, age, quantity, moisture content and ratio of hydrogen/oxygen availability at the time of decomposition (e.g. fat, hemicelluloses etc.). Coming on to a more localized level, the Ahmedabad Urban City has a population of 55.6 lakhs (2009) of which 78 percent is residing within the municipal area. Ahmedabad has been the primate city of Gujarat, the largest in terms of the population size and contribution to state income. Over the years, rapid urbanization has led to spreading of population outside the city limits [4]. Because of such high expansion in the amount of population has led to the generation of a tremendous amount of waste as well. Solid Waste collection and disposal in Ahmedabad is being carried out by Ahmedabad Municipal Corporation as an obligatory function. The total waste generated in the city is of the order of 2200 tons per day. Based on the 2005 statistical records by AMC are [4]. Table 1.
