Abstract

Landfill site’s selection represents a complicated process due to the large number of variables to be adopted. In this study, an arid area (Babylon Governorate as a case study) was selected. It is located in the middle region of Iraq. In this area, the landfills do not satisfy the required international criteria. Fifteen of the most significant criteria were selected for this purpose. For suitable weight for each criterion, the multi-criteria decision-making (MCDM) methods were applied. These methods are AHP and RSW. In the GIS software 10.5, the raster maps of the chosen criterion were arranged and analyzed. The method of change detection was implemented to determine the matching pixels and non-matching pixels. The final results showed that there are two candidate locations for landfills for each district in the governorate (ten sites). The areas of the selected sites were sufficient to contain the cumulative quantity of solid waste from 2020 until 2030.

K1⁄41 where Mi is the index of suitability for area i; n is the number of criteria; CWk is the relative weighting of each criterion; SCik is the rating value of area i under criterion k
15 maps of criteria were entered into the GIS to produce the final map for landfill siting

Summary

Introduction

Selecting an adequate site for landfill is necessary to protect human and environment. The selection site for a landfill should meet the following factors like rapid economic growth, social, population growth rate, improvements in living standards, growing environmental awareness, and government and municipality funding (Siddiqui et al 1996; Lin and Kao 1999; Javaheri et al 2006). Different effective techniques were used for disposition of the municipal solid waste in terms of solid waste management. Examples of these techniques are landfills, recycling, biological treatment, and thermal treatment (Kontos et al 2003; Moeinaddini et al 2010). After recycling large parts of their waste, the remaining materials are still to be dumped in the proper location (Yesilnacar and Cetin 2008; Kim and Owens 2010)
