Built for EU ESPR & PPWR
DPP-Polymer turns batch data from compounders and recyclers into audit-ready Digital Product Passports: material properties, recycled content, carbon footprint and chain of custody, published through a standard GS1 QR code.

Built for European industrial supply chains
Platform
Replace spreadsheets, PDFs and email chains with a single verified record that travels with every batch.
One structured passport per batch, aligned with the data requirements of the EU Digital Product Passport.
Every role sees exactly what it needs: administrators, auditors, customers, suppliers and the public.
Follow material from feedstock to finished compound, with every handover documented.
Compliance
Each passport field maps to a requirement, so auditors and buyers get answers instead of attachments.
| Framework | Reference | What DPP-Polymer records |
|---|---|---|
| ESPR | Regulation (EU) 2024/1781 | Structured passport per batch with a unique identifier, a QR data carrier resolving to a public passport, and lifecycle states (issued, revoked, superseded) that never delete history. |
| PPWR | Regulation (EU) 2025/40 | Post-consumer and post-industrial recycled-content shares and per-batch packaging compliance declarations. |
| REACH | Regulation (EC) No 1907/2006 | Substance of Very High Concern declarations above 0.1 % w/w, with portfolio-wide alerts. |
| ISCC PLUS | Mass-balance chain of custody | Chain-of-custody records and certificates reviewed by named auditors, with expiry monitoring. |
| GS1 Digital Link | ISO/IEC 18975 | Standard web URIs per GTIN and batch, printed as QR labels for packaging and delivery documents. |
| Product carbon footprint | Cradle-to-gate, kg CO₂e/kg | Footprint per batch from feedstock and process inputs, calculated with exact decimal arithmetic and stored with the passport. |
DPP-Polymer supports your compliance documentation. Responsibility for the accuracy of declarations remains with the manufacturer or economic operator placing the product on the market.
Security
Supply-chain data is commercially sensitive. Access is scoped by role and enforced on the server, not just hidden in the interface.
Administrator
Creates and manages passports, accounts and settings.
Auditor
Verifies certificates and custody records; reads audit trails.
Customer
Sees only the batches it has purchased.
Supplier
Submits batch data through a single-use invitation for review.
Public
Scans the QR code and reads the issued passport only.
Deny by default
Every API route and server action checks the caller's session or key on the server. A release that adds an unprotected endpoint fails its build.
Tamper-evident records
Passports are sealed with SHA-256 and every change is written to a hash-linked audit log that can be re-verified at any time. Records are revoked or superseded, never deleted.
EU data residency
Passport data is stored in a managed PostgreSQL database in Frankfurt, Germany, and served only over encrypted connections.
We work with polymer compounders and recyclers to issue their first passports on real material, so the data is in place before customers and regulators ask for it.
Scope
Pick one product line and the passport fields your customers ask for.
Onboard
Import batch data from your ERP or invite suppliers to submit it.
Issue
Publish passports, print GS1 QR labels and share access with auditors and buyers.
