Modeling the Spatial Arrangement of Plastic Recovery Centers (Case Study: Fars Province)

Today the most prominent health and environmental problems of cities is ascending trend of solid wastes that should be managed and the institutionalization of phenomena such as recycling, composting, and biogas energy recovery from municipal solid waste be taken into consideration. By considering more than 65 percent of organic wastes in urban garbage in the study area, there was observed a need to investment in the production of compost. Process to determine the suitability of land for locating compost production units requires consideration of multiple criteria. That makes use of multi-criteria analysis models and techniques in this paper. The application of TOPSIS Model as one of the leading techniques in multi-criteria decision making has been examined in experimental field of research and resulting output has been presented in the form of classified spatial suitability of land for the deployment of composting units. Results of the research indicate that the pixels in the output map of the model which were introduced by priority, had the optimal conditions in terms of criteria that were considered in locating. Therefore, this model can be used as a Decision Support System (DSS), in the modeling spatial arrangement of compost production centers (centers for composting municipal organic wastes).
