Sanitary landfill site selection using GIS-based on a fuzzy multi-criteria evaluation technique: a case study of the City of Kraljevo, Serbia

Abstract

Adequate disposal of municipal solid waste (MSW) is one of Serbia's most complex environmental challenges. The problem is more serious in urban areas, since large amounts of waste are disposed of in locations that do not comply with environmental, technical, and socio-economic standards. Such is the case for the city of Kraljevo, where about 116,000 inhabitants do not have a sanitary landfill facility. This research includes a multi-criteria analysis, conducted with the help of geographic information systems, to find a suitable landfill site location. After data collection, the first step was to process 15 environmental and socio-economic factors utilizing the fuzzy analytic-hierarchy process method. The second step comprised the visual analysis and selection of the ten most suitable locations from the synthetic convenience map. The third step involved the final ranking of sites by means of the fuzzy multi-objective analysis by ratio, plus the full multiplicative form method, based on four additional beneficial and non-beneficial criteria. The results show that sanitary landfill candidate site A4 is the most suitable location for constructing a sanitary landfill site due to its large area (569 ha) and relatively short distance from the urban zone (8 km). This study is the first to integrate geographic information systems and the fuzzy analytic-hierarchy process, multi-objective analysis by ratio, and the full multiplicative form algorithm for sanitary landfill selection. The results of the research can be used as a reference for safe waste disposal in the city of Kraljevo.

GIS-MCDM Integrated approach for suitable landfill site selection: Case study of the southwestern part of Bejaia Province, Algeria

“…The selection of a land ll site is closely related to the slope gradient of the terrain, as it in uences various aspects such as drainage patterns, soil erosion rates, site accessibility, visibility, and protection from prevailing winds (Abdo et al, 2023;Balew et al, 2022;Chabuk et al, 2016;Durlević et al, 2023). On the other hand, steeper areas may not be economically viable due to the need for excessive excavation (Bahrani et al, 2016).…”

“…Household waste arising from the daily activities of households, institutions and businesses represents a major challenge on a global scale (Durlević et al, 2023;Mallick, 2021;Zewdie & Yeshanew, 2023). The diversity of this waste, which varies considerably from region to region, encompasses organic and inorganic components and biodegradable and non-biodegradable fractions, ranging from food waste to packaging materials, glass, plastic and much more….…”

“…This type of procedure-multi-criteria analysis-considers various quantitative and qualitative criteria that need to be determined in order to find the best solution. In such situations, decision making is based on proper structuring and explicitly evaluating all criteria using appropriate models and software packages [39,40]. For the purpose of the study, the Best-Worst method (BWM) was used as one of the latest and most reliable multicriteria decision-making models [41].…”
