这项研究涉及的关键材料之间的制造和寿命结束的生命周期阶段的耗散损失。根据欧盟对关键材料的定义，根据现有数据对各种材料的耗散损失进行了筛选，并确定了最重要的数据差距。此外，耗散损失的分类方案（消散到环境中、消散到其他物质流中、消散到垃圾填埋场中）和评估其程度，并应用该分类方案进行了第一次定性评估。结合现有的关键性评估，该结果可用于生成金属图，该金属图指示用于详细分析金属耗散的未来研究需求。结果包括沿着选定的生命周期阶段的耗散损失（在可行的情况下）的定量估计，并讨论了分析和避免耗散损失，提高资源效率的研究需要。
This study deals with dissipative losses of critical materials between the life-cycle stages of manufacturing and end-of-life. Following the EU definition for critical materials, a screening of dissipative losses for the respective materials has been performed based on existing data and the most significant data gaps have been identified. Furthermore, a classification scheme for dissipative losses (dissipation into environment, dissipation into other material flows, dissipation to landfills) and for assessing their degree has been developed and a first qualitative assessment applying this classification scheme has been performed.In combination with existing criticality assessments, the results can be used to generate a map of metals indicating future research needs for analyzing metal dissipation in detail. The results include quantitative estimates of dissipative losses (where feasible) along the chosen life-cycle stages, and discuss research needs for analysis and avoidance of dissipative losses for improved resource efficiency.
