Every product has a backstory. The phone in your pocket began as ore in a mine, plastic pellets from a refinery, and components shipped between half a dozen countries before it ever reached you. The same is true of the food on your plate, the clothes in your wardrobe, and the steel beams above your head. For most of industrial history, that backstory has been almost entirely invisible to consumers, regulators, and often to the manufacturers themselves.
Digital tracing across value chains is the effort to change that. It is the practice of capturing, sharing, and verifying information about a product as it moves through every stage of its life, from raw material extraction through manufacturing and use, to eventual reuse, recycling, or disposal. Think of it as a machine-readable diary that travels alongside the physical product.
Why now?
Three forces are pushing this idea from a nice-to-have into a near-term reality. The first is regulation. The European Union’s Ecodesign for Sustainable Products Regulation (ESPR) is introducing Digital Product Passports, structured records that will accompany products in priority categories such as batteries, textiles, electronics, and construction materials. The Corporate Sustainability Reporting Directive (CSRD) is asking companies to back up environmental claims with auditable data.
The second is technology. Cheap sensors, QR codes, RFID tags, cloud platforms, and maturing data-sharing standards mean that capturing and exchanging information across organisations is no longer prohibitively expensive. Blockchain technology approaches add ways to share data without forcing every partner onto the same platform.
The third is risk. Pandemics, conflicts, and shipping disruptions have all exposed how little visibility most companies have into their supply chains. Better tracing is, at its core, better situational awareness.
What does it actually look like?
A useful way to picture digital tracing is in three layers. At the base, identification gives each batch, component, or product a unique digital identity, typically through a serial number, QR code, or embedded chip. In the middle, data capture records what happens to that item at each step: where it was made, by whom, how much energy was spent and various other inputs. At the top, sharing and verification makes the right information available to the right parties with appropriate trust, so regulators see compliance data and recyclers see material composition, while commercially sensitive details remain protected.
From principle to practice: the DigInTraCE approach
These ideas are already being built. DigInTraCE is developing an end-to-end traceability framework for complex value chains across pulp and paper, chemicals, wood and furniture, plastics, and textiles, sectors where materials are routinely reprocessed, mixed, and reused.
The framework brings the three layers above into a single interoperable system. Components receive unique digital identities at the point of manufacture; data on composition, processing conditions, and environmental impact is captured from sensors, quality systems, and operator inputs; and that information is then exposed selectively to suppliers, manufacturers, recyclers, and regulators.
A central piece of this is the Digital Product Passport, implemented on blockchain technology. The use of the blockchain technology addresses one of the deepest challenges in cross-company tracing: trust. No single partner owns the record, entries cannot be silently rewritten, and the provenance of every claim remains verifiable.
The aim is not blockchain for its own sake, but a passport that survives the realities of supplier substitutions, mergers, and decades-long product lifecycles. A circular economy needs records that outlast the companies that created them.
The hard parts
It would be misleading to suggest this is mostly a technical challenge. The harder problems are organisational. Value chains often span dozens of independent companies, each with their own systems, incentives, and concerns about confidentiality. A small supplier may have no IT department and no obvious reason to share data with a brand five steps downstream. Standards remain fragmented across sectors, and a passport is only as trustworthy as the information feeding it.
There is also a real question of purpose. Tracing for its own sake produces dashboards but little change. The systems likely to succeed are those tied to concrete decisions: choosing a lower-carbon supplier, recovering valuable materials at end of life, or proving compliance without months of manual audit.
A quietly important shift
Digital tracing will not, on its own, deliver a circular economy or fix global supply chains. But it provides something those goals have long lacked: a shared, evidence-based picture of what is actually happening. Once products can tell their own story, in a language both machines and people can read, much else becomes possible, from honest sustainability claims to smarter recycling and resilient sourcing.
The technology is largely ready. The harder work, agreeing on standards, building trust between partners, and connecting traceability to decisions that matter, is just getting started.
