Abstract: 

Today as the land-filling of solid wastes without taking into consideration the environmental issues would threaten the land greatly, the selection of an appropriate site for hygiene disposal of the wastes is a necessity. On the other hand, the site selection of optimum landfills for solid wastes is one of the most important aspects of waste management. In this paper, we have attempted to specify a landfill site selection for solid wastes of Bonab city, located on the North West Iran within the East Azerbaijan Province using the Analytic Hierarchy Process (AHP). The per capita tonnage of solid waste production in this city is about 820 g/day, most of which is created during spring and summer, rising at 70 tons per day. Taking into consideration all of the standards, necessities, and borderlines by AHP, we selected 9 suitable sites for solid waste disposal (landfill) in Bonab, through the application of GIS software (ArcView, and ArcGIS), and the application of Spatial Analysis.
Out of 9 permitted landfill options, site No.4 was chosen as the most optimum place for landfilling. This site is located in the south east of Bonab 7 km away from Malekan city road. Analytic Hierarchy Process (AHP) is one of the most widely used tools for multi-criteria decision making. We have applied this technique for the solid waste landfill site selection of the city of Bonab, located on North West Iran within the East Azerbaijan Province. The per capita tonnage of solid waste production in this city is about 820 g/day, most of which is created during spring and summer, rising at 70 tons per day.
The present landfill site is located in a region called Ghreh Ghoshoon in southern districts. The utilization of the site began in 2001; total of the land-filling area is predicted to be 10 ha. A traditional landfilling method used to be applied for waste disposal. There are 9 permitted zones for landfill site according to the maps and studies carried out. Using an AHP method, we chose the best option taking into consideration criteria such as geomorphology, environmental conditions, hydro climatic elements, land uses, and economic aspects.
