Industrial landfill site selection using Analytical Hierarchy Process (Case study: Razi industrial town of Isfahan-Iran)

Suitable landfill site selection is a significant step in the integrated management of solid waste. Because of some dangerous industrial waste, landfill site selection is more important. The selection process should be considered different criteria. The purpose of this study was to determine the appropriate location of industrial waste landfill Razi complex by using Analytical Hierarchy Process (AHP). In this study, three locations were proposed as site of landfill. Socio-economic (such as distance of industries, availability, cost of site preparation and access to soil cover) and physical factors (for example: dominant wind direction, soil permeability and ground-waters flow direction) were considered in the decision process. The Super Decisions software used to develop decision-making process. Based on the results, "2nd alternative"( mountain of Fish Pool) that is the current landfill site of Razi industrial town with a score of 0.593, based on software output, was chosen as the best alternative for disposal of Razi industrial wastes of Razi town-Isfahan. Inconsistency rate in this study, 0.039 was obtained.
