Site selection using multi-criteria decision is one of the most important abilities for GIS application, which can be helpful for finding the best site based on some favorite factors and constraints. Siting and finding the appropriate place is one of the most important parts of the landfill waste management system for a city. Koya city, with a population of 59,725, is one of the largest cities in the Erbil Province in Kurdistan Regional Government. Due to the recent population increase, the changes in the consumption habits of people and the use of packaging materials have all in recent decades increased the waste volume produced in the city. Despite this problem, there is not still an appropriate way for solid waste disposal in this city. One of the most important factors, which should be considered in the new waste disposal process, is the location of the disposal center. The suitability of selected site for the disposal center affects the amount of generated energy and the cost of disposal generation. Suitable sites should be determined based on technical, economical and socio-environmental issues. Therefore, multiple criteria should be considered in this process. GIS along with appropriate models and a spatial analysis method can be used to define the suitability of different locations for the construction of disposal centers. This research focused on determining suitable locations for the construction of suitable disposal centers. Our case study is Koya city in the Kurdistan Regional Government. At first, important parameters in a hazardous material disposal center siting for the studied area were identified. Then, the maps of the studied area were prepared and integrated. Boolean, index overlay was used for the integrating of maps.
