Abstract
Within the context of the Sustainable Product Initiative of the EU, product passports will likely be required in more and more sectors. However, their introduction is associated with challenges considering data collection and technical implementation, as the degree of standardization and availability of technical implementations for product passports is still low. To address these challenges, this work presents a digital product passport using asset administration shells to enable standardized connectivity via REST interfaces and, thus, standardized information exchange. The data model created contains submodels that specify information concerning the entire lifecycle of the product. Furthermore, these data enable the determination of the carbon footprint of the products as well as remanufacturing. The product passport will be implemented as a Gaia-X service to enable a secure and decentralized collection, exchange, and storage of product related data. The developed digital product passport and the Gaia-X ecosystem will be set up as demonstrators in the Learning Factory Global Production.
