METHANE EMISSION FROM MUNICIPAL SOLID WASTE BY GAS CHROMATOGRAPHYSANJAY SENGUPTA, J. C. TREHAN AND S. KOUL
An analysis by G.C. is presented of possible Indian production of methane from anaerobic decay of organic municipal solid wastes (MSW) in landfills. The maximum extent of anaerobic biodegradation of soil from MSW has been determined in this investigation. rpcc estimated global anthropogenic sources which landfills are expected to contribute 30-40 Tg/yr of methane and calculations show that the methane production from the whole world indicated by IPCC to be about 68 Tg/Yr which agrees with the upper limit of 70 TgiYr. Our incubation study reveals that the maximum biogradability of Indian MSW is about 45% at 35°C. The methane efflux obtained ranges from 0.3 to 0.7 mg/m/hr which shows that by this study this is only about 3% of the total methane budget from global. MSW indicating that methane release from MSW is one of the major sources contributing to global methane budget.
