Abstract

Nowadays,proper disposal of solid municipal waste is considered as one of the major environmental challenges inIran.Throw garbage near roads, agricultural land; it causes aesthetic degradation, agricultural pollution, surface and underground waters. This research uses the environmental, criteria to measure the potential of landfill sites in finding the location of disposal. The study area is Shahindej with adecomposable waste production of35tons per day.that peyear requires1.5hectares and occupies an area of25 hectares over a15year period. To find susceptible areasto landfill, recent research has combined the Fuzzy-ANP method byusing ArcGIS and SupperDecision software. In terms of standards such as environmental, geological conditions, and apply the limitations ofthe region suchas natural protected areas, water resources and agriculture to search for the best area. From the research results, two priorities were obtained: The first priority was only onesite with over25hectares square and a second priority was infour different ranges.By validating locations located with selected criteria, three locations were compatible with those criteria. Finally, with the reclassification and, the location on the eastern side of Mahmoudabad was better than the other two. The combination of fuzzylogic andANPmodel was the main innovation in this research, which resulted in a model with high flexibility and a near-realistic approach.
