Abstract

Sanitary disposal is one of the waste disposal methods, which contains a lot of harmful effects especially air pollution. As a result of the biodegradation process, pollutant gas contains Biogas, Methane, Carbon Dioxide, produced from landfills within which, Methane gas has a huge effect on air pollution in comparison to other gases. In this paper, seven cities of Iran, including Tabriz, Tehran, Shiraz, Bandar Abbas, Khoy, Astara, and Mashhad have been studied for the simulation of pollutant gas emissions according to various climatic conditions in them. After collecting population growth rate, type of landfill area, and the average lifetime of the displacement site pollutant Emissions from Landfills were simulated by using LandGEM software. The findings of this study demonstrate that the highest methane production rate among the studied cities, due to the humid and normal weather for Astara and the dry weather for other cities will occur in 1415 (2036) in Tehran. Using the results obtained from this study, it is possible to design methane gas collection systems for each site. therefore, in addition to the use of pollutant gases, its accumulation in the landfill site and the explosion probabilities are also prevented.
