Poster presented at the DPP4EU event by Jérome Dierickx (TerraMatters), Elena Hidalgo (CETIM Technological Centre), David Ariza (CETIM Technological Centre), and Beatriz Mafra (Made2Flow), 22 May 2026. This poster presents the approach of the Horizon Europe project TRUSTEX ("Advancing Sustainable Textiles in the Circular Economy through Innovative EPR Schemes") to Digital Product Passports (DPPs) for textiles. It addresses a core barrier: the textile sector combines fragmented supply chains with a shortage of harmonised standards, which makes it difficult to collect and exchange the information a DPP requires. TRUSTEX develops interoperable digital infrastructures that turn fragmented and heterogeneous data into standardised, regulation-ready outputs. The methods build on the Product Circularity Data Sheet (PCDS, ISO 59040), which communicates circularity attributes such as recycled content, repairability, and end-of-life options in interoperable formats and supports ESPR compliance, while noting that taxonomy gaps and sector-specific complexities remain unresolved. The workflow moves from data collection at brands and suppliers, through terminology mapping and PCDS data alignment, to a backend database, a blockchain layer, and a user interface that presents DPP information to the final user. Participants hold dynamic roles, for example manufacturer, waste manager, and final user, with restricted access so that only verified participants add data and only authorised users assign roles, which guards against fraudulent entries. The key innovations combine standardised APIs that integrate emission-factor databases, life cycle assessment engines, and verified batch-level supply chain data; AI-driven data validation paired with blockchain trust mechanisms that detect inconsistencies and complement missing information with industry-verified secondary sources; and a blockchain architecture that records a cryptographic fingerprint of the data instead of the data itself, so tampering becomes detectable without exposing confidential business information. Role-based access control limits each participant to their area of responsibility. The conclusion sets out four design goals for DPP success: data maturity alignment, one-way protection through hashing, double-entry prevention, and universal access via the ERC-1155 standard for compatibility across textile applications. The poster argues that digitalisation is a fundamental requirement for overcoming current barriers to DPP adoption in the sector.
