Design Approach of Bio-Gas Digester for Energy Harvesting by Municipal Solid Waste Management in Agartala City

Municipal solid waste is considered as a potential source of energy as it can yield a good quantity of bio-gas through organic digestion process. At the same instant this mode of waste management can be implemented in large scale for the developing countries where the fraction of organic materials is higher in solid waste. Application of appropriate design principle as well as the optimization tools upon the controlling parameters of a particular biogas digester results in a drastic development of energy recovery from municipal solid waste (MSW). The present study illustrates the categories as well as the design aspects of biogas digester considering the baseline data of Agartala city, India. The design approach narrates the necessity of 18 nos of biogas digesters of 7.60 m dia and 7.00 m height for Agartala city by the year 2021. However shortage of field base data of solid waste production & characterization for newly developed urban bodies of the sate emerges as a major challenge in formulizing the bio-gas production plan for such areas. The study will serve as a baseline study for further project planning regarding energy source generation through bio-gas technology in urban and semi urban zones.
