Study on site selection of municipal solid waste landfill based on FAHP and FTOPSIS techniques in Barasat Municipality Area, West Bengal, India

In recent years, India has experienced a dramatic rise in waste generation due to rapid urbanization coupled with economic growth and higher consumption patterns. Thus, finding an ideal site to dump a city’s solid waste is crucial for managing waste in growing urban areas (e.g., ULBs, Class I and II Cities). In this study, ideal municipal solid waste landfill sites were delineated in Barasat Municipality Area (BMA) using Fuzzy Analytical Hierarchy Process (FAHP) and Fuzzy Technique for Order Performance by Similarity to Ideal Solution (FTOPSIS) model. As output, 8 ideal solid waste landfill sites were identified which were further assessed based on expert’s views and post-analysis field observation. Finally, sites 1b and 7 were selected as the most ideal for proposing new waste landfill locations in Barasat Municipality Area (BMA). The outcomes from this study will help local authorities make informed decisions about planning, choosing the best locations for waste landfills in the near future and sustainable waste management. • Waste generation in India has increased from 98.79 g/capita/day in 2017–2018 to123.45 g/capita/day in 2021–2022. • West Bengal is ranked 3rd (69.11 %) in terms of gaps in solid waste management in India with 9475 TPD in 2021–2022. • Present research adopts an integrated approach for selecting solid waste landfill sites, considering TRASH criteria. • Initially this study proposes a number of 8 potential MSW landfill sites covering 1.84 % area of BMA. • Post-field validation has identified 2 sites (i.e., 1b and 7) as highly suitable by following the SWM 2016 regulation.
