Purpose: The study explores the integration of blockchain technology with Digital Product Passports (DPP) to facilitate information transparency to address industry-wide concerns. Methodology: This research employed a qualitative exploratory design, utilizing detailed semi-structured interviews with individuals involved in the relative field. The research synthesized insights from industry reports, academic discourse, and empirical data to offer a holistic perspective on the subject matter.

Findings: The study reveals a pressing need for standardized and transparent mechanisms for sharing information within the industry's supply chains. As an initial stage, adopting a Digital Product Passport contains many challenges. The research identifies three key categories of challenges (i.e. Technological, Organizational, and Regulatory challenges) and tries to investigate the role of blockchain technology in the supply chain to solve them.

Implications: The integration of DPPs and blockchain holds the potential to revolutionize supply chain collaboration, enhance consumer trust, and facilitate the transition to a circular economy. The study underscores the importance of stakeholder collaboration, education, and the establishment of industry-wide standards to unlock the full transformative potential of these technologies.

Value: This research contributes to the growing discourse on circular supply chains by explaining the role of DPPs and blockchain technology in promoting transparency, and traceability. The study offers a comprehensive framework for understanding the data requirements of digital product passports, bridging the gap in the existing literature. The findings serve as a foundation for informed decision-making by industry practitioners, policymakers, and researchers.
