Assessment of Bio-Gas from Municipal Solid Waste for Generation of Electricity - A case study of Agartala city

摘要

Municipal solid waste (MSW) management seems to become one of the major concerns of the modern city planning. The increasing quantum of MSW has pressed hard on policymakers to introduce sustainable modes of waste management techniques considering the aspect of 4 R Principle. At the same instant the energy demand of modern city life has also appeared to be a matter of study with the changing environmental and socio-economic scenarios. On the verge of these dual challenges selection of proper technology for sustainable waste management with sufficient scope of energy recovery is the call of the period. Considering the aforementioned fact an attempt is made in this paper to evaluate the potential of MSW generated in Agartala city for generating bio-gas on preliminary basis for electricity generation. The study shows that with the present trend of waste quantity and quality approximately 249.41 MT of MSW will be produced per day by 2021 empirically yielding 52376.10 m~3 of methane and this may further increase to a value of 108559.50 m~3 by the year 2051 when the approximate generation of MSW may reach 516.95 MT per day for the city of Agartala.
