摘要

The selection of efficient landfill sites is a major problem in waste management for rapidly growing urban cities. In this study, a GIS-based approach combined with the Multi-Criteria Decision Making (MCDM) was used to identify the suitable landfill sites in Dindigul, India. The key parameters, such as slope, drainage, surface water body, habitation, protected areas, road and railway network, soil, landuse pattern, geomorphology, geology, groundwater level, and other site-specific parameters, were analyzed following Central Pollution Control Board 2007 guidelines. Thematic maps were developed and analysed using a GIS-based MCDM technique, identifying 13 preliminary sites. After assessing the Google Earth imagery, 7 potential sites were found. Following an appropriate field investigation, two sites, namely Site-3 and Site-5, with an area of 44.56 hectares and 12.85 hectares, were found to be suitable for Municipal Solid Waste disposal, respectively. Furthermore, both identified facilities are located away from the residential area and outside the city ensuring public health safety. The methodology also aligns with the Sustainable Development Goals (SDGs), especially SDG 11 (Sustainable Cities and Communities), SDG 12 (Responsible Consumption and Production), and SDG 15 (Life on Land). The proposed method is adoptable for waste management planning in other cities, promoting sustainable landfill site selection.
