THE MODELING OF CARBON DIOXIDE, METHANE AND NON-METHANE ORGANIC GASES EMISSION RATES IN SOLID WASTE LANDFILL IN CITY OF JAHROM, IRAN
Abstract
Introduction: Under the influence of existing microorganisms in soil, the landfilled municipal solid waste, would produce and release high quantities of carbon dioxide, methane and non-methane organic compounds into the atmosphere in anaerobic conditions. The aim of this study was to estimate the amount volume of produced gasses in the landfill located at city of Jahrom.
Materials and methods: To conduct this research, the primary data including waste composition, waste density, waste production capitation, the weight of the annual produced waste were collected using experimentations and calculations. These data were then used in LandGEM for the purpose of landfill gases volume estimation. The Screen view was then used for modeling of pollutants dispersion into atmosphere in 15 km radius around the landfill.
Results: Studies suggest that the waste generation in city of Jahrom is 313.35 g/person.d. The climax of carbon dioxide and methane production in this landfill in 2028 was equal to 10570000 m3/year. Estimation shows that by recycling the obtained methane in this landfill, it is possible to generate 8375 MW of energy by 2016. It is also indicated that the concentration of produced pollutants in the landfill is calculable in 15 km radius.
Conclusions: The obtained results from this study could be used to determine the role of Iran in global emission of greenhouse gasses and be considered for the Iranian energy production planning’s.
