Fecha de publicación: -- Fuente: WIPO "circular economy" The present disclosure provides a system for creating and managing a Consolidated Digital Product Passport (cDPP) for a complex product system. The system comprises a hierarchical passport structure (402) configured to organize digital product passports from a sub-component level to a system level, a data collection module (412) for collecting product information from different business management software systems, and a data aggregation module (414) for aggregating data from lower-level digital product passports to create higher-level digital product passports. The system may utilize blockchain-based data storage (416) for data immutability and traceability, and include an update mechanism (418) for dynamically updating digital product passport information throughout the product lifecycle. The system enables real-time tracking and management of product information across multiple levels of complexity, enhancing transparency and sustainability in product lifecycles.
