Landfill Site Selection Process

Landfill site selection is a complex process, which requires evaluation of multiple criteria. Decision makers often face difficulties in making the right decision in multiple attribute environment. Multi-criteria decision making (MCDM) has been found to be a useful approach to solve such kind of problems. In this paper, an integrated Fuzzy-AHP-TOPSIS based methodology is applied to solve the municipal solid waste landfill site selection problem in the city of Mumbai, India. The methodology has been developed under Indian socio-economic and regulatory set-up. The Fuzzy Analytic Hierarchy Process (F-AHP) is used to make pairwise comparisons of identified criteria by expert from various domains for assigning weights and rank to the decision criteria.…show more content…
Landfill sites are considered as undesirable facilities and are usually opposed socially (Rodriguez et al., 2006, Colebrook and Sicilia, 2007). Due to scarcity of land and increasing amount of waste, it is very much necessary to use the land resource thoughtfully. Landfill site selection in an urban area, especially the coastal region, is a critical issue because of its enormous impact on the environmental health of the region and the economy. During the siting process the challenge is to make an environment friendly and financially sound selection. Siting a suitable landfill location deal with the choice of a set of points, taking into account different criteria and verifying a given set of limitations, in addition optimally fulfilling the needs and the purpose. The lack of ability to properly site landfills has led to a great deal of controversy and negative effects. Public awareness of environmental impacts, and distrust for scientific studies to determine siting locations, certainly leave waste managers with little room for error. Facility location models are widely used for locating waste landfill sites to minimize exposure to the public and…show more content…
Many authors have applied multiple objective techniques in the waste facility location analysis (Stowers and Palekar, 1993; Erkut and Verter, 1995; Current and Ratick, 1995). Cheng et al. (2002) addressed the need for using MCDM methodologies in solid waste management systems because these systems can have complex and conflicting impacts on different stakeholders. Harvey and O’Flaherty (1972) developed a model which determines the optimal locations of the landfill sites as well as the locations of the transfer stations. They implemented their model on a fourteen-district problem where there were five alternative sites for the transfer stations and three possible landfill
