Abstract

Recovery of Rare Earth Elements From End-of-Life Magnets has moved quickly from a niche engineering question to something a
wider community can now investigate with reasonably reliable tools, but the evidence behind it has not always kept pace. We pull
together the current evidence for recovery of rare earth elements from end-of-life magnets, covering the methodological, practical,
regulatory and cost angles, with an eye on where practice has genuinely settled and where engineers and reviewers are still
largely working it out for themselves. Selective, context-specific adoption looks better supported by the evidence gathered here
than either broad rollout or blanket avoidance.
