As global industries confront mounting complexity, regulatory mandates, and urgent sustainability targets, end‑to‑end transparency has become nonnegotiable. Design for Traceability (DfT) delivers a transformative blueprint—encoding traceability into the very DNA of products and materials. By harnessing Smart Identification Technologies (SIT)— including Radio-Frequency Identification (RFID), Near Field Communication (NFC), QR codes, IoT sensors, and blockchain—DfT establishes immutable “digital DNA,” realized through interoperable Digital Product Passports (DPPs) and Material Passports (MPs). These passports grant real‑time visibility, secure authentication, and frictionless data exchange, catalyzing circular resource loops while ensuring compliance with evolving regulations.The DfT framework is anchored by five interdependent pillars: Lifecycle‑Centric Design: Embeds traceability at inception via modular architecture, durable materials, and design-for-disassembly, extending product life and simplifying end-of-life recovery. Digital Traceability Infrastructure: Constructs a secure, interoperable data ecosystem by integrating SIT and distributed ledger technology, enabling continuous monitoring, analytics, and decision support through DPP and MP integration. Circular Business Models: Transitions from one‑time sales to service‑based offerings, remanufacturing, and R‑strategies (Reduce, Reuse, Recycle), unlocking new revenue streams and preserving asset value. Stakeholder Collaboration: Builds shared platforms and decentralized governance to unite manufacturers, regulators, consumers, and recyclers in transparent data‑sharing networks, strengthening trust and supply‑chain resilience. Regulatory Alignment: Integrates traceability into corporate strategy to anticipate stringent sustainability mandates, leveraging digital audits and transparent reporting for streamlined compliance. By interweaving these pillars, DfT empowers organizations to mitigate supply‑chain risks, optimize resource utilization, and accelerate the shift toward a resilient, transparent circular economy. This holistic framework equips policymakers, industry leaders, and designers with actionable strategies to embed sustainability, accountability, and innovation at every stage of the product lifecycle.
