There is a claim that repeats itself in every DPP vendor pitch deck, every sustainability officer’s briefing, and every CIRPASS-2 working group session when the conversation turns to ESPR implementation: *“Compliance will require significant new data collection infrastructure.”*
This is wrong. And it is falsifiable with one question: ask the person making that claim whether they have ever opened a bulk Lab Test Report from an accredited textile laboratory.
The data is already there. It has been there for every bulk shipment since the brand last updated its Quality Management Report requirements. The problem is not a data problem. The problem is that no one has built the system that reads it.

## The Durability Index Is Not a New Test
The Durability Index V2.0 — which I deposited on Zenodo (DOI: 10.5281/zenodo.20034567) and formally submitted to the European Commission Joint Research Centre, Unit B5, Seville, on 21 February 2026, together with an industrial dataset of 120 laboratory test reports — is computed exclusively from test data that is already mandatory in standard textile sourcing practice.
Nine ISO parameters. Pilling resistance (ISO 12945-2). Abrasion resistance (ISO 12947-2). Tensile strength (ISO 13934). Tearing strength (ISO 13937). Bursting strength (ISO 13938-2 — a binary structural gate: either the fabric holds or it does not). Colour fastness to washing (ISO 105-C06). Colour fastness to light (ISO 105-B02). Dimensional stability (ISO 5077). Seam slippage (ISO 13936). One garment-level protocol: thirty domestic washing cycles per ISO 6330, followed by appearance grading per ISO 15487.
Every accredited laboratory that issues a bulk Lab Test Report for an apparel brand already produces the data for eight of these nine fabric tests as a matter of routine. The reports are physically attached to the shipment. The brand QC team files them. They sit in SharePoint folders, in supplier portals, in email attachments marked “BV Report TGL#008” or “(5921)209-0190.”
Reeco reads those reports. It aggregates the scores. It outputs a number on a 200-point scale with a defined performance band — ACCEPTABLE, GOOD, EXCELLENT, or UNACCEPTABLE — and a cryptographic reference to the methodology document. That number goes into the Digital Product Passport. Zero additional laboratory cost. Zero new equipment. Zero parallel QC infrastructure.
The DI does not introduce new tests. It formalises what the industry has already paid for.

## The Mass Balance Problem — and Why It Matters for the DPP
A GRS Transaction Certificate certifies kilograms. It says: this supplier holds a certificate for X kg of recycled material under the Global Recycled Standard, valid until a given date, issued by a specific certification body.
ESPR requires a Digital Product Passport at unit level. Not at kg level. Not at shipment level. At the level of the individual garment — or, in the case of fabric, the individual batch with a defined GSM, cut width, and yield coefficient.
The gap is structural: a TC certifying 3,792.20 kg of recycled pre-consumer flax does not tell you how many metres of fabric that covers, how many garments can be declared compliant, or whether the brand’s DPP declarations remain within the certified balance.
Reeco bridges this gap algorithmically. The mass balance engine computes: GSM × cut width × yield coefficient = per-unit fibre mass. It divides the TC certified weight by that per-unit mass to determine how many units the TC actually covers. It tracks each DPP issuance against the remaining balance. When the declared units approach the certified limit, the system documents the shortfall and informs the brand. The brand retains autonomous decision-making authority — always. What Reeco provides is the auditable evidence that the brand was informed, at the moment of issuance, with a cryptographically signed record of the computation.
This is not a dashboard. A dashboard shows you numbers. This is a verification layer — one that produces a signed audit trail that a market surveillance authority, a customs inspector, or a third-party auditor can interrogate independently.

## A Live Credential. Not a Concept.
Today — 17 May 2026 — I am publishing the first fully-formed Reeco DPP with mass balance coverage and Durability Index embedded in a live, publicly resolvable UNTP 0.7.0 Verifiable Credential.
The product: TGL Linen 80/20 GRS Woven Shirting, 130 gsm, 55” cut width. Composition: 80% Flax (Linen), 20% Recycled pre-consumer Flax (Linen) certified GRS. Transaction Certificate: CUC-02403817, issued by Control Union Certifications B.V., Zwolle, Netherlands, dated 14 March 2023. Certified weight: 3,792.20 kg GRS. Gross shipment: 19,344 kg. Seller: Tung Ga Linen & Cotton (Changzhou) Co., Ltd., Jiangsu, China.
Durability Index: 132/200. Band: ACCEPTABLE. Based on Bureau Veritas test report (5921)209-0190, article TGL#008, 100% linen woven print bulk. Bursting gate: PASS (structural conformity confirmed). Garment Durability Test (ISO 6330 × 30 cycles + ISO 15487 grading): pending — this is the only component the Lab Test Report does not routinely include. Everything else was computed from an existing report.
The credential is live at:
**https://ia.reeco.eco/v0.7/dpp/cc8d2131-463f-4965-8018-1d513fc63b1c**
The signed JWS (Ed25519, kid: ed25519-1, issuer: did:web:ia.reeco.eco) is at:
**https://ia.reeco.eco/v0.7/dpp/cc8d2131-463f-4965-8018-1d513fc63b1c/jws**
You can retrieve it right now. You can verify the signature against the DID document at https://ia.reeco.eco/.well-known/did.json. You can confirm that the credentialSubject contains materialProvenance with mass fractions, performanceClaim with the GRS TC reference and the DI score, and the DOI pointing to the published methodology.
This is UNTP 0.7.0 — the UN/CEFACT specification for which Reeco is listed in the official Software Register (MR !732, merged April 2026). The credential conforms to the W3C Verifiable Credentials Data Model 2.0. It is machine-readable, cryptographically tamper-evident, and independently resolvable by any UNTP-compatible verifier without contacting Reeco.

## What This Means Operationally
If you are a brand sustainability officer, this is the question your DPP provider cannot avoid: *show me a live credential — not a mockup, not a sandbox URL, not a slide — that contains fibre composition with mass fractions, a TC reference that maps to a verifiable certificate number, a mass balance computation, and a durability metric traceable to an ISO methodology and a publicly accessible DOI.*
If they cannot show it to you, they are selling you a document format. ESPR is not a document format. ESPR is an enforcement framework — one that will require exactly this level of verifiability when market surveillance authorities begin systematic inspections, with the first textile delegated acts expected no later than 2027.
Reeco is currently extending this infrastructure to DPP Providers operating under the Global Textile Scheme (GTS) framework — the B2B licensing channel through which the mass balance methodology becomes available at scale across the EU supply chain.
The Durability Index was calibrated on 120 real industrial lab reports transmitted to JRC Unit B5 on 21 February 2026 in response to a JRC raw-data request. The mass balance methodology is the same one I formally documented in the CIRPASS-2 survey (Contribution ID: bb6997ac, January 2026) — the structural gap between GRS per-kg certification and ESPR per-unit DPP requirement. Both methodologies are published, versioned, and DOI-referenced.
I am not describing what Reeco will do. I am describing what Reeco did — today, with a real TC, a real Lab Test Report, and a live endpoint that you can query right now.
The system is live.
