The average municipal solid waste (MSW) produced from a city of 1 Million people at a rate of 200 g/d/capita is decomposed by a method known as the Bangalore process (anaerobically). Assume that MSW contains 30% inorganic solids and 65% of solids get converted into various gases out of which 30 % is methane which has a calorific value of 36000 kJ/m³. Then calculate the total energy produced in million megajoules (1MMJ = 10¹²) in a year. Given that volume of gases produced at STP is 0.9m³/kg.
