Fast population growth and urbanization has increased the generation of municipal solid waste in Oman. Currently, Oman relies on landfills to handle growing amounts of waste, which has burdened the existing solid waste management infrastructure. This situation calls for establishing incineration plants that can considerably reduce the volume of waste, and can simultaneously produce electricity. However, one of the crucial steps in the planning of an incineration plant is the selection of an appropriate site that can overcome environmental and economic implications and eliminate community dissatisfaction. Therefore, to select an optimal site for incineration plant in Muscat and South Batinah governorates, where landfills receive the highest waste amounts per day, this research identified 11 criteria that cover the environmental, economic, and social concerns. These criteria were processed by combining the multicriteria decision making (MCDM) method and geographical information system (GIS) software where the suitability of individual criteria were evaluated and then integrated using the weighted overlay analysis to generate a final suitability map for incineration site selection. The final suitability map indicated that only 2% of the land is suitable for setting up an incineration plant in the study area, and the most suitable location with adequate area was found in Barka wilaya of South Batinah governorate. Due to the escalation in MSW generation, Oman is looking for alternative strategies to reduce the volume of MSW. This has led to country's interest in establishing a waste-to-energy plant (particularly incineration) in the future. However, locating a suitable site for the installation of an MSW incineration plant in Oman has never been studied before. Therefore, to bridge the gap in knowledge, this research focuses on selecting a suitable site for a municipal solid waste incineration plant using GIS and multicriteria decision analysis. This study highlights the suitability of Muscat and North Batinah governorates of Oman where landfills receive huge amounts of MSW on a daily basis and are close to becoming saturated. Moreover, the suitability of land in both governorates is assessed to overcome environmental and economic implications and eliminate community dissatisfaction. This research not only provides the level of suitability of land in both governorates, but also selects a suitable site, which will be beneficial for the government of Oman in future when making a decision regarding the location of the plant.
快速的人口增长和城市化进程导致阿曼的城市固体废物产生量不断增加。目前，阿曼主要依靠垃圾填埋场来处理日益增长的垃圾量，但这已经给现有的固体废物管理基础设施带来了负担。因此，建立焚烧厂来显著减少垃圾量并同时产生电力是当务之急。然而，在规划焚烧厂时，至关重要的一步是选择一个合适的厂址，该厂址能够克服环境和经济方面的影响，并消除社区的不满。因此，为了在接收每日最高垃圾量的马斯喀特和南巴提奈省选择一个焚烧厂的最佳厂址，本研究确定了 11 项涵盖环境、经济和社会问题的标准。这些标准通过多标准决策 (MCDM) 方法和地理信息系统 (GIS) 软件进行处理，对各个标准的适宜性进行评估，然后通过加权叠加分析进行整合，生成焚烧厂址选择的最终适宜性图。最终的适宜性图表明，在研究区域内，只有 2%的土地适合建立焚烧厂，而在南巴提奈省的巴尔卡威尔亚发现了最适合的、具有足够面积的位置。由于城市固体废物产生量的增加，阿曼正在寻找减少城市固体废物量的替代策略。这导致该国对未来建立废物能源厂（特别是焚烧厂）产生了兴趣。然而，在阿曼，从未有人研究过为安装城市固体废物焚烧厂选择合适厂址的问题。因此，为了填补知识空白，本研究使用 GIS 和多标准决策分析来选择适合的城市固体废物焚烧厂厂址。本研究重点关注接收大量城市固体废物的马斯喀特和北巴提奈省，这两个省的垃圾填埋场已经接近饱和。此外，评估了这两个省的土地适宜性，以克服环境和经济方面的影响，并消除社区的不满。本研究不仅提供了这两个省的土地适宜性水平，还选择了一个合适的厂址，这将有助于阿曼政府在未来做出有关工厂选址的决策。
