Despite environmental regulations in Ecuador, particularly in the Province of Azuay, the solid waste final disposal management is still a socio-environmental problem, worsened by weak governance processes. The province has three sanitary landfills with almost expired service lives. The site selection was based on circumstantial reasons, which makes landfills more likely to cause environmental pollution and, therefore, have negative implications for public health. The largest landfill serves Cuenca and also leases service to other small cities. The remaining two are small and, accordingly, have limited technology and fewer resources. In this context, the main aim of this study is to evaluate the terrain of the province to find the most suitable area for landfill siting. A multi-criteria decision analysis, integrated with a geographical information system and analytical hierarchy process methodology, was conducted. Fourteen factors and seven constraints were simultaneously analysed, divided into technical, environmental, social, and economic categories; 15 of these criteria were from the Ecuadorian Unified Text of the Secondary Legislation of the Environmental Ministry. According to the results, 76.17% of the territory is not suitable for landfill implementation, and the unrestricted area represents the remaining 23.83%. The highest landfill suitability index (70–81%) is located in the south of the province in Santa Isabel, Oña, and Nabón cantons, which are dry and clay-rich areas.

尽管厄瓜多尔，特别是阿苏埃省有环境法规，但固体废物的最终处置管理仍然是一个社会环境问题，由于治理程序薄弱而恶化。该省有3个卫生垃圾填埋场，使用寿命将近。选址的依据是环境因素，这会使垃圾填埋场更容易造成环境污染，因此对公共卫生产生负面影响。最大的垃圾填埋场不仅为昆卡省提供服务，还向其他小城市提供服务。其余两个很小，因此技术有限且资源较少。在这种情况下，本研究的主要目的是评估该省的地形，以找到最适合填埋场选址的区域。多标准决策分析，与地理信息系统和层次分析法相结合。同时分析了14个因素和7个限制因素，分为技术，环境，社会和经济类别。这些标准中的15条来自环境部二级立法的厄瓜多尔统一文本。根据调查结果，该地区76.17％的土地不适合实施垃圾掩埋，而其余的23.83％则为无限制区域。最高的垃圾填埋适宜性指数（70-81％）位于该省南部的圣伊萨贝尔，奥尼亚州和纳蓬州，这些州是干燥且粘土丰富的地区。环境，社会和经济类别；这些标准中的15条来自环境部二级立法的厄瓜多尔统一文本。根据调查结果，该地区76.17％的土地不适合实施垃圾掩埋，而其余的23.83％则为无限制区域。最高的垃圾填埋适宜性指数（70-81％）位于该省南部的圣伊萨贝尔，奥纳和纳邦州，这些州是干燥且粘土丰富的地区。环境，社会和经济类别；这些标准中的15条来自环境部二级立法的厄瓜多尔统一文本。根据调查结果，该地区76.17％的土地不适合实施垃圾掩埋，而其余的23.83％则为无限制区域。最高的垃圾填埋适宜性指数（70-81％）位于该省南部的圣伊萨贝尔，奥尼亚州和纳蓬州，这些州是干燥且粘土丰富的地区。
