Abstract

CH4 has a high potential for energy production and by utilizing the proper technology, large amounts of energy can be extracted from it. This study aimed to estimate the amounts of methane emissions from the municipal solid waste landfill in Yasuj city using LandGEM software. The LandGEM model which is used for this aim is based on input data of open landfill year, land closure year, methane production rate, potential methane production capacity, and waste acceptance rate. According to the results, methane gas production during the years 2009, 2010, 2011 and 2012 was obtained to be 250, 275, 303, and 330 m3/h respectively. The results also showed that maximum methane production rate occurred during the years 2010–2012 and then reduced with a soft slope from 2012. The method and results of this research can be used for design and execute of methane gas collection systems and also, control of greenhouse gases emission for the landfills.

Highlights

The production of municipal solid waste (MSW) increases with socio-economic condition development [2,3]
Methane emission estimates based on LandGEM is the practical method in nature which vary according to the landfill management and waste composition were considered while developing this method [15]
The methane gas emission has been estimated using the LandGEM model for Yasuj landfill

Summary

Introduction

The production of municipal solid waste (MSW) increases with socio-economic condition development [2,3]. Rapid population growth has further added to the amount of municipal solid waste production. The government of Iran has a policy that each province or city should have a comprehensive solid waste management plan. Many technical and economic problems prevent a comprehensive waste management plan. As landfill is a low-cost and technically feasible method, has a high of attention in solid waste management plans [2,4,5]. The unavoidable after-effects of solid waste disposal in a landfill are gas and leachate generation due to climate condition, microbial disintegration, refuse properties and landfilling operations [6,7]
