Zenodo (CERN European Organization for Nuclear Research)

Abstract

This document establishes a comprehensive framework for digital traceability in the critical raw materials (CRM) supply chain, focusing on secure, verifiable data management to ensure transparency, accountability, and sustainability. It outlines the implementation of a Digital Product Passport (DPP), leveraging blockchain, distributed ledger technologies (DLTs), and Life Cycle Assessment (LCA) to meet regulatory and industry standards. Key topics include CRM certification, environmental compliance, material fingerprinting, risk assessment using the P.A.S.T.A. methodology, and the creation of a unified Digital Materials Passport Data Model.
