Evaluation of management of composite waste containing wax with different decision-making techniques

Composite wastes containing wax are difficult to manage in sustainable waste management systems due to their complex structure. It is important to take a holistic approach in terms of environmental, economic, and technical aspects while determining the most appropriate evaluation method. At this point, it is possible to use Multi-Criteria Decision Making Techniques (MCDM), in which the most suitable alternative can be selected with the help of certain criteria in solving problems in numerous fields. Therefore, in this thesis, the management process of composite wastes containing wax has been evaluated with a holistic approach by using Analytical Network Process (ANP) and TOPSIS method. The criteria determined are weighted by Entropy, SWARA, and CRITIC methods. With the results obtained from each weighting method, separate evaluations were made with TOPSIS and ANP. According to the results, it was determined that the pyrolysis alternative is the most suitable option.
