All kind of living necessitates food to produce energy and release waste as by-product. Then, it is a ring of the food chain. The circumstance changes in industrial environment where a huge amount of waste is produced. Today many public or private industrial institutions are faced to new management disciplines as environmental protection, responsibility for solid waste collection and recovery [6]. The recovery of exploitable waste decrease the volume of the waste going to land filling area, with important grades. But the percentage of recovery and the expenses varies for different collection method of solid waste. The exploitation of the solid waste involves a collection process as clean as possible. There are many methods of collection. This study will help us to understand which collection method is the best for the current situation. Since the paper and the carton paper are the most produced exploitable solid waste in Turkey, it seemed adequate to observe this system. Based on the data received from an institution executing the system of collection from manufacturers we will illustrate the current situation. Then, we will observe other alternatives by using data received from Ministry of Environment and Forestry (MEF) of Turkey. The application part of the study includes the selection of the best collection method by using a multiobjective decision making method named fuzzy goal programming (FGP) approach and then a multi-criteria decision making method named fuzzy TOPSIS.
