Project EXTRADE developed an innovative process for recycling rare earths (RE) from permanent magnets used in small applications. To assess the potential of further research from lab scale toward industrialization, this study performs economic and environmental evaluations. Because data are incomplete at current levels of process development, this study propagates uncertainty into the results. Results show that the EXTRADE process, as a complement to the Hard Disk Drive (HDD) waste management system currently in operation in France, could be both economically profitable and beneficial in terms of climate change. However, at this stage of development the price of output products is a key determinant of the economic profitability while still particularly uncertain. Also, the EXTRADE process may offer a climate change benefit due to the substitution of recycled RE oxides for those produced from primary resources (80% chance to be superior to 990 tonnes CO₂‐eq over 5 years). The amount of the waste recycled is another key, uncertain parameter regarding both the environmental and economic benefits provided by the process.

从磁铁中回收稀土的经济评估和碳足迹：实验室规模的评估为工业化铺平了道路

EXTRADE项目开发了一种创新方法，可从小型应用中的永磁体中回收稀土（RE）。为了评估从实验室规模到工业化的进一步研究的潜力，本研究进行了经济和环境评估。由于当前过程开发水平的数据不完整，因此本研究将不确定性传播到结果中。结果表明，EXTRADE工艺作为对法国目前正在运行的硬盘驱动器（HDD）废物管理系统的补充，可以在经济上既有利可图，又对气候变化有利。然而，在目前的发展阶段，产出产品的价格是经济盈利能力的关键决定因素，尽管仍然特别不确定。也，5年内₂ eq）。回收废物的数量是有关该过程所提供的环境和经济效益的另一个关键，不确定的参数。
