Digital Product Passports for Circular Electronics: A Review of Data Requirements and Custody

Abstract

There is real interest in digital product passports for circular electronics right now, and real uncertainty about exactly where it
delivers the most value. We pull together the current evidence for digital product passports for circular electronics, 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.
