Durgapur, an industrial city, is the second and third-largest city in West Bengal in terms of population and area respectively. The city is suffering from an enormous generation of waste and improper waste management. The wastes are dumped in an unscientific and unplanned way, negatively impacting the environment and public health. Hence, the National Green Tribunal has advised the city planners to find new landfill sites following the Central Pollution Control Board's guidance. This paper focuses on the new landfill site selection of Durgapur city using the Multi-criteria Decision Making (MCDM) methods with Geographic Information System (GIS). The methodologies used for the site selection processes are GIS (for mapping the 14 criteria and overlay analysis) and MCDM methods: Analytical Hierarchy Process, Straight Rank Sum Method, and Ratio Scale Weighting Method (to derive the weights). Finally, the five landfill sites are selected after calculating the change detection.
