Estimation of Methane Generation from the Landfill Sites
Landfill Gas (LFG) recovery is a very important element of an integrated solid waste management. The use of the landfills for solid waste disposal will continue to be the predominant method worldwide. This includes the information on how LFG to energy technologies worldwide can be implemented to extract the energy locked up in the landfills. This contributes the consolidation of knowledge in the field of LFG.Provide an overview of the status and prospects of LFG including the technical aspects and benefits of LFG recovery. Estimate of the methane generation estimation once the empirical constants have been determined by using the LFG models.In the present study, various physico-chemical parameters of the MSW were analysed to characterize the waste dumped at Okhla landfill sites in Delhi, India, which shows that it contains a high fraction of degradable organic components. The decomposition of organic components produces methane, a significant contributor to global warming. Based on the waste composition, waste age and the total amount dumped, a first-order model (FOD) was applied to estimate the methane generation potential of the Okhla landfill site, which yields an estimate of 25.98×106 m3/year.
