Abstract: 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 multi-
objective decision making method named fuzzy goal programming (FGP) approach and
then a multi-criteria decision making method named fuzzy TOPSIS.
