The large amount of end-of-life (EoL) reverse osmosis (RO) membrane modules needed in desalination processes represents an important opportunity for material valorization. Alternative waste management routes are being developed worldwide to give them a second life within the Circular Economy (CE) principles. The aim of this study is the potential location identification for an EoL-RO direct recycling plant in the Segura River Basin, one of the most important desalination areas of Spain (with more than 42% of the Spanish desalination capacity). Using Geographical Information System (GIS) technologies, a Multi-criteria evaluation (MCE) methodology has been used for the suitability assessment for the membranes recycling plant best location. The evaluated criteria have been divided into restricted (natural protected areas, rivers, roads, reservoirs, supply channels and flood-prone areas) and conditioning (land use, topography and distance to shoreline). The spatial analysis shows that the 0.8% and 4.7% of the river basin area are optimally and highly suitable, respectively, for the recycling plant location. On the contrary, the totally restricted areas are more than 23% of the basin. This work will be the base for further environmental and economic studies of the reverse logistics: EoL-RO modules collection and the distribution of recycled products.

海水淡化过程中需要大量的报废（EoL）反渗透（RO）膜组件，这为材料增值提供了重要机会。全球范围内正在开发替代性废物管理路线，以使它们在循环经济（CE）原则范围内重生。这项研究的目的是在塞古拉河流域（西班牙最重要的海水淡化地区之一）（西班牙海水淡化能力的42％以上）中建立EoL-RO直接回收厂的潜在位置。使用地理信息系统（GIS）技术，已将多标准评估（MCE）方法用于膜回收厂最佳位置的适宜性评估。评估标准已分为限制条件（自然保护区，河流，道路，水库，供应渠道和洪水多发地区）和条件（土地使用，地形和距海岸线的距离）。空间分析表明，流域面积的0.8％和4.7％分别最适合于回收工厂的位置。相反，完全限制的面积超过流域的23％。这项工作将为进一步进行逆向物流的环境和经济研究奠定基础：EoL-RO模块的收集和回收产品的分配。
