38. 联合国大学的研究填补了废物管理、水再利用和废物量化等专题领域的数据和数字空白。例子之一是智能水域项目，该项目旨在制定促进废水资源智能再利用的系统框架。此外，以可靠的电子废物数据为基础，才能确保开发用于回收的基础设施，并制定和有效实施健全的政策和法律文书。联合国大学主办的可持续循环项目(2022 年改由联合国训练研究所主办)，是一项包括参与电子废物统计的主要国际利益攸关方在内的全球性努力，目标是协助各国编制健全的国家电子废物数据。
38. UNU research bridges data and digital gaps in thematic areas such as waste management, water reuse and waste quantification. An example is the SMART-WaterDomain project, which is aimed at developing a systematic framework to facilitate the smart reuse of wastewater resources. In addition, ensuring the development and efficient implementation of recycling infrastructure, sound policies and legal instruments requires a foundation of reliable e-waste data. The UNU-hosted Sustainable Cycles (SCYCLE) project (hosted by the United Nations Institute for Training and Research since 2022) is a global effort that includes key international stakeholders involved in e-waste statistics. Its objective is to assist countries in the production of sound, national e-waste data.
