Demonstration of a Digital Product Passport System for Second-Hand Electronic Devices

The foundation for the Digital Product Passport (DPP) was presented in the recent European Ecodesign for Sustainable Products Regulation (ESPR) in July 2024. DPP systems will provide ICT support to increase the circular economy of products significantly. With the DPP, a significant step forward will be taken by providing comprehensive, trusted, and publicly accessible product information for items or batches regarding digital records. Currently, the DPP building is undergoing a standardization process. Nevertheless, commercial players are preparing DPP systems but mainly with a proprietary implementation, making it difficult for researchers to experiment. In this demo paper, we will show an open-source implementation of a DPP system for managing the lifecycle of second-hand electronic devices such as computers. Our system is oriented towards the use cases of economic actors such as repairers, refurbishers, and the customers of these devices. Our system integrates a blockchain-based registry for the actors to trust the data and operations. The implementation of the demo DPP system is publicly available and can be deployed as a set of microservices.
