Optimal Positioning for Disposing Sanitary/Hospital Wastes, Case Study: Bonab Township

As one of the most dangerous forms of the urban wastes, sanitary and hospital wastes can threaten seriously citizens’ health if they are ill-managed. Optimal positioning of disposable sanitary/hospital wastes is a most significant stage in disposal management of such dangerous wastes. Taking advantage of effective factors in positioning optimal sites for disposing the sanitary/hospital wastes, this study has tried to locate the optimal sites and areas in Bonab Township for disposing the wastes using quantitative models. A descriptive-analytical method was used to materialize our functional-developmental objectives in this study. Network analysis models pragmatics and Decision Making Trial and Evaluation Laboratory (DEMATEL) were used to locate optimal and proper spaces for disposing the wastes. 12 factors were considered to develop spatial layers. A fuzzy logic was used for measurements and different fuzzy operators were used in the spatial layers overlapping process. The results indicate that the existing site for hospital waste disposal in Bonab Township will not meet the increasing needs of the city whose population is growing in future. Finally, the optimal site was selected out of five spatial areas introduced by the mixed models using both spatial assessment and measurements. The site is supposed to be used for managing the hospital/sanitary wastes disposal in this township.
