Abstract :

Background and Objective: Hazardous waste management is one of the most important issues of today. Failure to pay attention to proper planning and management can cause surface, groundwater, soil and air pollution on a large scale. On the other hand, more attention to environmental criteria in national macro-planning has led to the creation of a scientific attitude to bury hazardous waste by selecting suitable landfills for these materials, which lack of attention and observance of scientific and biological principles have polluted water, soil, air and endangered the health of humans and other living organisms. The purpose of this study is to locate hazardous waste landfills using multi-criteria decision making and GIS methods.Material and Methodology:  In this research, using the Delphi method to determine the criteria and ANP, TOPSIS and GIS software, a suitable place for landfilling in Lorestan province (for which no landfill has been considered so far) has been specified.Findings: The area of the city of Azna, Aligudarz, Kuhdasht and Poldokhtar as the best place for special waste landfill in the province were introduced.Discussion and Conclusion: The results show that two TOPSIS and AHP in the GIS in locating many landfills is capable to perform that corresponded with research in other areas.
