A MULTI-CRITERIA DECISION-MAKING MODEL FOR SELECTING LOCATIONS FOR WASTE-TO-ENERGY PLANT IN HO CHI MINH CITY

Abstract

The rapid socio-economic development has led to an increase in waste generation, posing a significant challenge for many countries, including Vietnam. This necessitates the adoption of advanced and sustainable waste management solutions to replace traditional landfill disposal. One widely adopted approach is Waste-to-Energy (WtE) technology, which not only alleviates pressure on existing landfills but also generates renewable energy, contributing to environmental protection and meeting the growing energy demand. This study analyzes and evaluates potential locations for WtE plant construction using the hybrid AHP-TOPSIS method. Data were collected based on six criteria categorized into three main groups: environmental, economic, and social factors, in Ho Chi Minh City. The analysis of 24 locations identifies Cu Chi as the most suitable site for a WTE plant, minimizing environmental impacts and promoting sustainable development in Ho Chi Minh City.
