Abstract

The study aimed to study selection of electronic waste collection site based on 6 environmental factors including distance from community, slope, digital elevation model, distance from water resources, distance from road and land use integrated with analytic hierarchy process (AHP) model in QGIS Version 2.18.5. AHP model was designed based on questionnaire, made by 7 experts, to examine important environmental criteria and assign importance values of each criteria for selecting suitable electronic waste collection site. In addition, suitable electronic waste collection sites derived from AHP were verified by field survey. The results showed that percentage of very suitable, moderate suitable, less suitable and unsuitable sites for electronic waste collection were 13.26 %, 58.10 %, 21.77 % and 6.87 %, respectively.
