Sustainable Landfill Site Selection in Urban Areas: Case Study of Millenium City in India

Landfills remain the predominant approach to managing solid waste in urban settings due to their cost-effectiveness, particularly in developing nations. In this regard, landfill site selection is a serious issue in the urban planning process because of its implications for the economy, environment, ecology, and public health. Municipal Corporation Gurugram records indicate that the city alone generates solid waste of about 1100 metric tons per day. The city's growing urban population and rapid expansion as a commercial and financial center presented numerous waste management difficulties. Existing studies lack comprehensive integration of multi-criteria decision analysis and GIS technologies for landfill site selection in rapidly urbanizing cities like Gurugram. In the present study, multi-criteria decision analysis and GIS technologies are used to identify suitable sites for landfills, considering most environmental factors. With the rate of population and settlements increasing, it is suggested that the landfill site serve for at least 20 years. In accordance with the regulations outlined in the Solid Waste Management Rules of 2016, a meticulous process was undertaken to identify and prioritize the ten most crucial criteria for evaluation in prescribed methodologies. The study's conclusions could help municipal planners and waste management authorities create an effective solid waste management system that takes into account all possible advantages and disadvantages.
