Day to day increase in waste generation demands Renewable technology for solid waste management for an effective economic and social growth of the people. Anaerobic digestion is a biological method used to convert organic wastes into a stable product for different applications such as cooking, electricity generation, etc. with reduced environmental impacts. The biogas produced can be used as an alternative renewable energy source.Biogas productions is a great substitute for fossil fuels. This process can also utilize MSW for production of electricity. Electricity generation through biogas helps in solving environmental issues, electricity shortage and Solid waste management problem. This paper focuses on technical feasibility and electrical potential mappingof Haridwar City through Anaerobic Digestion Technology. Key Words: Waste to Energy, Anaerobic Digestion, Municipal Solid Waste, Solid Waste Management, Electricity Generation, Renewable Energy I. INTRODUCTION he current trend of economic growth and standard of living of people increases municipal solid waste (MSW) generation and effects on current landfill scenario, unavailability of land, open burning landfill causes pollution and has greatly effects on public health. There is an urgency for an effective solid waste management due to all of these reasons. WTE incineration helps in reducing greenhouse gases (GHGs) by avoiding dumping to landfill, foils the methane emission from landfill and generating renewable energy in form of electricity which further helps in reducing dependency on fossil fuels. In Incineration Technology MSW is combusted in presence of oxygen. Heat produced then utilized to produce steam which turns the turbine and then alternator to produce electricity. Harmful flue gases are treated and then released in atmosphere. By product is utilized in cement factory. In Landfill gas recovery Anaerobic biodegradation results in methane production in landfill which is recovered to produce either electricity or heat. In Biomethanation technology. Organic matter of MSW is converted to biogas by means of anaerobic digestion in presence of methanogenic bacteria. This biogas can further be utilized for cooking or electricity production. In Refuse Derived Fuel technology fuses whole MSW irrespective of individual calorific value of organic and inorganic matter. It forms briquettes and pellets which can be used further as a fuel in many applications. Currently largest source of GHGs emissions in the world are landfills with an assessment of almost 21% of the total methane production. As a GHG Methane is 21 times stronger than carbon dioxide. II. LITERATURE REVIEW Mufeed Sharholy et.al (2007) [1] used ArcGIS technique which included MSW sample collection and questioner survey on randomly selected houses and concluded that 45.3% of organic matter and 40% miscellaneous material (glass, paper, plastics etc.) and mentioned the qualitative and quantitative characteristics of MSW for MSWM for developing GIS maps for city of Allahabad. He also explained MSWSM collection, storage and disposal methods. Tsai et.al (2014) [2] did content and chemical analysis of MSW from year 2008 to 2012 with the use of CHP technology and compared the efficiency of plants of Taiwan with different parts of Europe, Germany and Netherlands. He also classified plants on the basis of capacity of waste handling, power generation and efficiency was done and discussed use of district heating and cooling and its use and advantage. S Rathi et.al (2014) [3] used Dulong Formulae heat energy in incineration technology to calculate and analyse potential generation of electricity in Kanpur city of 33MW from MSW of 1200 tonnes/day by considering conversion efficiency, station allowance, unaccounted heat loss and net power generated and classified solid wastes on physical and chemical composition. NIE et.al (2008) [4] explained new technology of circulating fluidized bed and emission of reduction by using equipment such as house filtration, flue gas cleaning and activated carbon in incinerator, adopted by 30 plants for development of China. Biodegradable matter shares 31-36% of total MSW in big cities and 65% in small cities having calorific value of around 5000KJ/Kg. Dioxin emission was limited to 1.0ng TEQ/Nm 3 . Ojha et.al (2011) [5] explained, classified and compared cities on the basis of population, MSW composition, total waste generated; very big city, big city, medium city, small city and calculated potential of 1700 MW electricity from WTE incineration with some solutions and suggestion to problems occurring in MSWM. Arena et.al (2015) [6] proposed the opinion to solve waste problem as using it as a resource. He explained WTE technology was successful and reliable because of thermal conversion, heat recovery and air pollution T
