The increasing focus of the European Union on a sustainable and circular economy in the industrial sector has led to the development of the Digital Product Passport (DPP). It acts as a digital identity assigned to physical prod-ucts, providing a structured record of essential lifecycle information, including composition, maintenance, environmental impact, and end-of-life manage-ment. By facilitating data flow among authorities, supply chain businesses, and consumers, the DPP enhances traceability and regulatory compliance, serving as a key lever for circular economy strategies. Integrating the DPP into a PLM system presents significant challenges, such as ensuring data standardization, achieving interoperability, and maintaining compliance with evolving regula-tions. This paper explores the theoretical integration of the DPP into a PLM system, analyzing technical requirements, exploring potential architecture, and assessing implications for product data management. The research identifies key functional areas where the DPP can enhance PLM capabilities, such as da-ta exchange, regulatory compliance, and supply chain transparency. By pro-posing a conceptual framework for DPP-PLM integration, this work aims to lay the foundation for future implementations, thereby contributing to a more sustainable and circular approach to product lifecycle management.
