Evaluation of Sustainable Solid Waste Systems Using the ENTROPI-TOPSIS Method

Abstract

Solid waste management has become a critical necessity for both developed and developing countries. Globally, socio-economic, demographic, and environmental factors are increasing the volume of solid waste day by day.  The lack of consistent waste data reduces the effectiveness of management strategies in this field and creates significant obstacles, particularly in achieving various development goals related to promoting environmental sustainability and the circular economy. This study aims to prioritize solid waste management strategies in line with environmental sustainability, public health, and sustainable development goals, based on various criteria. In this context, five alternative solid waste strategies—incineration, biological treatment, landfilling, composting, and gasification—were weighted using ENTROPI-TOPSIS methods based on nine criteria. The findings indicate that the criteria of greatest importance, in order, are CO₂ emissions, recycling, and energy production. Additionally, the findings reveal that biological treatment, incineration, and composting are the most suitable solution alternatives.
