Landfill locate in Bukan by Boolean logic andAnalytical Hierarchy Process (AHP)

Population growth, industrial development and increase in quality and quantity of consumer products has led to the increase of waste generated. According to Department of Municipal Utilities of Bukan an average of 189 tons of waste is generated daily, that means per capita waste generation is about 640 to 820 grams per day, which is slightly higher than the country average (the equivalent of 600 to 800 grams per day).Therefore the selection of a municipal waste landfill is one of the most important steps and goals in management of municipal solid waste of Bukan.
This study is analytical-descriptive, therefore by full recognition of locating criteria such as communicational lines, distance between rural and urban areas, surface waters privacy, distance from fault, land usage, slope and the direction of slope which play critical rule in selecting the waste landfill site and utilizing Boolean Logic and weighting of layers using AHP model in GIS software, the best location for landfill waste is selected based on mentioned criteria.
Findings: Results obtained from the poll of experts in the AHP model has showed that Hydrology criterion with a weight of 0/235 as the most important and land use with a weigh of 0/023 as the least important one have been known. Also after extracting the information layers of criteria from the maps and prioritizing locating ranges in 5 classes, it has been found that there are notable zones to landfill waste in the city of Bokan which ultimately a zone with the area of 138 Hectares is chosen. The selected are is located between Bokan and Simineh and to the south of Kani Shaqaq village.
Discussion and Generally, considering the results of the presented research, it can be said that prioritised ranges for positioning can be determined by combining the Boolean logic method and AHP model, acceptably.
