Circlechain Circular Digital Passport Platform issues immutable digital passports for products, materials, and waste using a private consortium blockchain. Each item is assigned a passport that records its full lifecycle—from production to reuse or recycling. The platform offers Traceability, TrackChantier 4.0 for construction site waste tracking, and Déchetterie 4.0 for waste center management. Users—such as developers, artisans, and waste handlers—report data through mobile or desktop portals. Smart data flows enable automated reporting to Eco-organisms and environmental regulators, simplifying compliance with French REP regulations. Digital passports improve trust among stakeholders and support sustainable resource recovery. The system enhances waste tracking, operational efficiency, and circularity metrics, while minimizing fraud and paper administration. Target users include public authorities, NGOs, waste authorities, waste producers (construction industry), and recycling intermediaries. The solution enables streamlined collaboration, real-time transparency, and optimized material reuse.
