Municipal solid waste landfill site selection using analytic hierarchy process method for Tafresh Town
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2015, Vol 6, Issue 1
Abstract
Waste disposal is the last stage of waste management which is the subject of a precise process including site selection, preparation and operation; every stage needs research and management actions. Selection criteria include engineering, environmental, and economic criteria. Geographical Information System (GIS) is a framework for storage, maintenance, management and analysis of geographical data and it has been designed for working with data that has spatial and descriptive dependency. No site selection study focusing waste disposal has been performed in Tafresh town in Iran, which is located at 222 Km southwest of Tehran and have a population of over 16900 people and total waste production of 7665 tons per year. This study has been done using Analytic Hierarchy Process (AHP) in which criteria such as distance from residential areas, distance from roads, land use, distance from wells, distance from faults, geology, distance from sensitive ecosystems, etc. were used and after data geo referencing, the weighting of the criteria and adjusting them with the geographical features of the area, data overlaid and finally three locations proposed for landfill were introduced in Tafresh town. Among the proposed areas, one was selected as the best location according to the hypotheses. The obtained results of this study may be helpful for policy makers of Tafresh town.
