Abstract


Managing Municipal Solid Waste in order to control waste materials in Tehran Metropolitan with a population of over 8.5 million persons and daily production of 7500 tons of trash seems an evitable necessity. Daily production of such amount of trash and accumulation of them in the southern part of Tehran (Kahrizak) due to lack of proper and standard methods of landfilling have caused severe problems by creating a latex lake of twelve hectares. Among these problems, penetration of infection and contamination to underground waters, causing excessive problems for soil and agricultural lands can be mentioned. In such conditions caused for Tehran, lack of solution finding for the issue would bring heavy outcomes for the Tehran Metropolitan in terms of environmental and economic issues. In this paper, efforts are taken to find a new place as a landfill by applying sustainable development approach. For this, in order to use the criteria propounded in sustainable development, multi-criteria decision making methods has been applied for weighing and spatial analysis has been used to combining them for indicating the most appropriate site. In this way, the new site would be selected by observance of sustainable development would be a place with the least environmental and social damages while being economically affordable.
