A comprehensive multi-criteria decision making-based land capability assessment for municipal solid waste landfill sitting

Abstract

The municipal waste management has always been one of the most challenging environmental concerns. Today, although different strategies have been developed, sanitary disposal of municipal waste is still considered as one of the most widely used alternatives, especially in developing countries such as Iran. To investigate the land capability of Pishva, for landfill sitting, the important criteria were categorized in two groups of ecological and socioeconomic and then a multi-criteria decision-making model was used with decision-making trial and evaluation decision-making trial and evaluation (DEMATEL)-analytical network process (ANP) approach. First and foremost, the interaction of criteria was determined implementing DEMATEL. It was found that the soil depth criterion not only is the most effective but also is the most influenced one. Moreover, ANP structure was developed to weigh the criteria. In comparison to socioeconomic criteria, ecological ones play a more significant role. Afterwards, factor maps and constraints were standardized using fuzzy and Boolean logic, respectively, and all layers were combined to generate the final capability map of Pishva applying WLC method. The capability map showed that 71% of the area is not capable of landfilling, and only 5% of Pishva has a high capability. The results proved the great effectiveness of the methods proposed in this study.

Decision making method based on Pythagorean fuzzy sets and its application to solid waste management

“…The results obtained from the proposed method suggests that 'operational and maintenance challenges' is most influenced criteria. This result is not consistent with an empirical study conducted by Soroudi et al [35] where 'soil depth' is the most influenced criteria. They utilised the DEMATEL and the analytical network process to determine interaction and weight of criteria of SWM.…”

A worldwide meta-analysis review of restriction criteria for landfill siting using geographic information systems

“…The distance from fault lines was used in approximately 37% of articles reviewed, and the values vary from 60 m, used by Ersoy and Bulut (2009), to 1500 m, used by Soroudi et al (2018). In the IQR, the distances are between 100 and 500 m, the median is 160 m, and the mean is approximately 315 m (Table 4 and Figure 7d).…”

“…On the other hand, some authors also used a maximum distance restriction from roads, since the proximity to roads should decrease the costs of making new road connections as well as transportation and collection costs. Some of the authors that used the maximum distance from roads in decreasing order are Nas et al (2010) with 10000 m, Al-Ruzouq et al (2018) with 6000 m, Bahrani et al (2016) with 5000 m, Soroudi et al (2018) with 4000 m, and Babalola and Busu (2011) with 2000 m. Besides, some authors, such as Aksoy and San (2019); Moeinaddini et al (2010), also used the visibility from roads and residential areas as one of the factors considered to find an area for a landfill. Therefore, the distance from roads could be classified in both economic and social restrictions, but in this review, we opted to classify it as an economic restriction.…”

Redesigning the Municipal Solid Waste Supply Chain Considering the Classified Collection and Disposal: A Case Study of Incinerable Waste in Beijing

“…Liu et al analyzed the natural environment and human environment of Beijing by GIS and, using the multi-objective programming method, planned the layout of the waste collection station [23]. Furthermore, the disposal of waste has the most serious impact on the environment, so the location problem of waste disposal plants is mainly discussed, and the layout of landfill is mostly focused on plants' location selection [24][25][26][27][28]. The energy conversion rate also is one of the factors that affect the location of waste disposal plants.…”
