Rare earth elements (REE), composed of the lanthanides (La-Lu) and Y, are used in many emerging technologies (e.g. permanent magnets, batteries, video displays and alloys). Although REE are strategic elements, with China as the leading REE producer (71% in 2018) (Shen et al., 2020), their production is not without environmental impacts.
