Optimizing landfill site selection by using land classification maps

Abstract

Municipal solid waste disposal is a major environmental concern throughout the world. Proper landfill siting involves many environmental, economic, technical, and sociocultural challenges. In this study, a new quantitative method for landfill siting that reduces the number of evaluation criteria, simplifies siting procedures, and enhances the utility of available land evaluation maps was proposed. The method is demonstrated by selecting a suitable landfill site near the city of Marvdasht in Iran. The approach involves two separate stages. First, necessary criteria for preliminary landfill siting using four constraints and eight factors were obtained from a land classification map initially prepared for irrigation purposes. Thereafter, the criteria were standardized using a rating approach and then weighted to obtain a suitability map for landfill siting, with ratings in a 0-1 domain and divided into five suitability classes. Results were almost identical to those obtained with a more traditional environmental landfill siting approach. Because of far fewer evaluation criteria, the proposed weighting method was much easier to implement while producing a more convincing database for landfill siting. The classification map also considered land productivity. In the second stage, the six best alternative sites were evaluated for final landfill siting using four additional criteria. Sensitivity analyses were furthermore conducted to assess the stability of the obtained ranking. Results indicate that the method provides a precise siting procedure that should convince all pertinent stakeholders.

“…Step 1: selection of environmental decision criteria 100 In this study, the environmental factors and indicators selected were based on the literature that takes into account the environmental impact susceptibility associated with landfill sites (Leão, Bishop, and Evans 2004;Butt, Lockley, and Oduyemi 2008;Eskandari, Homaee, and Mahmodi 2012;Gbanie et al 2013;Butt et al 2014;Khan and Samadder 2015;Maanifar and Fataei 2015;Motlagh and Sayadi 2015;Eskandari et al 2015; 105 Bahrani et al 2016;Chabuk et al 2016;Chonattu, Prabhakar, and Harikumar 2016b;Demesouka, Vavatsikos, and Anagnostopoulos 2016;Chonattu, Prabhakar, and Harikumar 2016b AQ6 ; Kharat et al 2016;Eskandari, Homaee, and Falamaki 2016;Yıldırım and Güler 2016;Zhang et al 2016). In addition, existing guidelines, relevant legislation and regulations, experts' opinions obtained in informal meetings, and available relevant 110 data were considered in the development of the EISM.…”

“…It is not appropriate to have landfills close to surface water sources or in areas where the water table level is shallow due to the higher 155 contamination risk (Qian, Koerner, and Gray 2002;Sharma and Reddy 2004). Several studies have taken into consideration these aspects (Gbanie et al 2013;Eskandari et al 2015;Khan and Samadder 2015;Maanifar and Fataei 2015;Motlagh and Sayadi 2015;Bahrani et al 2016;Chabuk et al 2016;Chonattu, Prabhakar, and Harikumar 2016b;Yıldırım and Güler 2016). In this study, we used the surface water resources environ-160 mental indicators of (i) distance to rivers and lakes and (ii) flood frequency, while, for underground water resources we used the environmental indicators of (i) distance to wells and (ii) depth to water table.…”

Analysis of Multi-Criteria Evaluation Method of Landfill Site Selection for Municipal Solid Waste Management

“…1. In order to identify a landfill site, an evaluation process is required for optimal and best site selection [15]. This site selection process is increasingly becoming more complex and difficult, and it must be in accordance with rules and regulations governs by the authority [16].…”

Chelate-enhanced phytoextraction and phytostabilization of lead-contaminated soils by carrot (Daucus carota)

“…As result of industrialization, several hazardous inputs are daily imposed to soils worldwide (Nouri et al 2014;Davari et al 2015;Eskandari et al 2015). In recent years, many agricultural soils have been contaminated by inorganic and organic wastes due to mining activities, industrial emissions, application of sewage sludge and waste disposals (Asadi Kapourchaal et al 2011;Eskandari et al 2012;Farrokhian Firouzi et al 2015).…”
