Methane Flux Estimation in MSW Open Dump Site by In-Situ Measurement and IPCC (DM and FOD) Model

Abstract

This paper deals with the use of different methods to predict methane
generation on an open dump site. Methane recovery data obtained on
site as part of a research program being carried out at the Devguradia
dumpsite, Indore, is analyzed and used to obtain field methane emission
in three seasons. Field data from Municipal solid waste (MSW)
dump site are presented and discussed measured in-situ technique
i.e. using close chamber methods. The Intergovernmental Panel on
Climate Change (IPCC) Default Method (DM) and First order Decay
(FOD) method is used to estimate methane generation. It is found
that despite the assumptions and the simplicity of the adopted procedures,
the values methane obtained are slightly varying to those
measured in the field. The values obtained were 4.5, 2.9 and 0.35
Gg/y respectively.
