One of the main tasks of the CIRPASS project is to explore the benefits and barriers to the use of a Digital Product Passport by key actors along the value chain. To do this, we consulted over 40 stakeholders and qualitatively analyzed six DPP use cases linked to specific circular economy actions in the three priority sectors (Battery, Electronics and Textile). The exploration of the DPP use cases in circular economy activities of the three sectors has revealed a compelling potential to address persistent data challenges. This report summarizes our main findings which highlight the ability of the DPP to reduce information asymmetry and foster trust in second-hand markets and life-extension applications, as well as to increase the recovery rate of valuable materials and products at end of their life (or use). These findings advocate for large-scale piloting of DPP use cases to further quantify the benefits and enrich the repository of use cases. Finally, we also identified barriers to the deployment of the DPP, which are summarized in the form of actionable recommendations.
