A decision support mechanism in the determination of organic waste collection and recycling center location: A sample application for Turkiye

Abstract

The location problem of organic waste collection and recycling plants is a significant concern for policy makers in developing countries. Factors such as rapid population growth, unplanned urbanization, and limited resources pose challenges to the efficient management of organic waste. Inadequate waste disposal practices not only endanger the environment and human health but also hinder the development of sustainable and livable cities. Therefore, it is crucial to address the specific challenges associated with locating organic waste collection and recycling facilities to ensure effective waste management and promote environmental sustainability. This study aims to identify the most appropriate location for an organic waste collection and recycling facility for compost production. This study involves identifying the most influential aspects of organic waste collection and recycling center location selection through a literature review and expert opinion. The Analytical Hierarchy Process (AHP) methodology with fuzzy interval type-2 (T2F) sets is employed to weight the criteria. The COmbinative Distance-based Assessment (CODAS) approach is extended in a T2F environment to better reflect the uncertainty and evaluate the alternative locations. The study concludes by revealing the optimal location for the food waste collection center for Trabzon city in Turkiye. To verify the validity and reliability of the proposed integrated methodology, a comparative analysis was also performed using various decision-making methods.
