HYDROUSA_ Evidence Matrix dataset

The evidence matrix consists of cases demonstrating water reuse and recovery of other resources in cities, rural settlements, agriculture, coastal areas and industries, using technologies with Technology Readiness Level (TRL) 6 and above to recovery resources from wastewater, including NBS and any others. The aim was to identify cases demonstrated in Europe, and if the course of the search yielded cases demonstrated outside of Europe, but transferable to Europe, these were also taken up in the matrix (7 non-European cases, all located in the Southern Mediterranean). Demonstration cases include Horizon 2020 CIRC, WATER and WASTE and other EU-funded projects (total 96 cases), but also nationally funded projects (5 cases) and private sector projects (6 cases). European and national-level policy and framework initiatives for circular water economy were collected, including signed Innovation Deals (1 Innovation Deal for water reuse identified), public strategies, action plans, laws, Directives, Regulations, financing programmes, platforms, tools and frameworks, all at EU level or national level in EU member states. The collection process involved screening of online databases and reports related to circular economy, with a focus on water and wastewater, as well as reports published by the European Commission, the European Environment Agency, EUROSTAT, Cradle to Cradle, the Ellen MacArthur Foundation and Circle Economy, among others. The cases were categorized with key attributes to provide an overview and allow for filtering and targeted searching by users. Key information was retrieved from project websites, Cordis, reports and online articles.

本证据矩阵收录多类示范案例，覆盖城市、乡村聚居区、农业、沿海区域及工业领域的水回用与其他资源回收实践，所用技术的技术就绪水平（Technology Readiness Level，TRL）达6级及以上，可从废水中回收资源，包含自然基解决方案（Nature-based Solutions）及其他相关技术。本数据集的构建目标为筛选欧洲境内的示范案例；若检索过程中获取非欧洲境内但可迁移至欧洲应用的案例，同样将其纳入本矩阵（共7个非欧洲案例，均位于地中海南部区域）。示范案例涵盖地平线2020（Horizon 2020）框架下的CIRC、WATER及WASTE等欧盟资助项目（总计96个案例），同时包含国家资助项目（5个）与私营部门项目（6个）。本次收集了欧盟及欧盟成员国国家级的循环水经济政策与框架举措，包括已签署的创新协议（已识别出1项水回用相关创新协议）、公共战略、行动计划、法律、指令、法规、融资计划、平台、工具及框架等。数据收集过程中，研究人员对循环经济相关的在线数据库及报告（重点关注水与废水领域）开展筛选，同时纳入欧盟委员会、欧洲环境署、欧盟统计局（EUROSTAT）、从摇篮到摇篮（Cradle to Cradle）、艾伦·麦克阿瑟基金会（Ellen MacArthur Foundation）及循环经济联盟（Circle Economy）等机构发布的报告。所有案例均通过关键属性进行分类，以提供整体概览并支持用户开展筛选与定向检索。核心信息均从项目官网、欧盟研究与创新项目数据库（Cordis）、各类报告及在线文章中提取。
