Hazardous waste management demands detailed planning due to the risks posed by hazardous wastes on public and environment and high investments required. This study aims to provide a framework that leads Ministry of Environment and Forestry (MoEF) in planning of hazardous waste facilities to be built. This framework considers the facility and transport cost along with impacts of hazardous waste management. The linear optimization models for several scenarios are developed in order to evaluate possible approaches in management of hazardous wastes. During cost calculations economy of scale principle is considered. Estimation of impact includes not only population impact but also environmental impact for which a methodology is developed in the scope of this study. This methodology considers the effect of hazardous waste transportation on lakes, rivers, dams, seashores, forests and agricultural areas, which are defined as vulnerable environmental elements. Evaluation of the results suggests that establishment of designated hazardous waste facilities with co-incineration practices and use of transfer stations give most satisfactory outcome. Co-incineration practices decrease incineration costs, which has the highest contribution to overall cost while transfer stations provide great improvement in total impact. Locations for recovery, treatment, incineration facilities and landfills are selected. These selections both confirm decisions made in the past regarding existing locations and become suggestions for locations for new facilities. It is observed that integrated facilities are favored. The importance of countrywide planning should also be underlined. It is believed that results of this study provides a basis to evaluate possible alternatives for further improvement of hazardous waste management system in Turkey that would be most useful to MoEF.
