Abstract

Circular economy strategies, driven by national and EU regulations and market demand, are reshaping the manufacturing industry towards sustainability and resilience. Closed-loop supply chains, integrating secondary materials, aim to minimize waste and carbon footprint while enhancing supply chain flexibility. Leveraging online B2B marketplaces, manufacturers, suppliers, and other stakeholders engage in dynamic networks, optimizing resource utilization through competitive service offerings. This work explores the integration of stakeholders across the product lifecycle into a digital marketplace with secure data exchange, following IDSA and Gaia-X concepts. It highlights the Digital Product Passport's (DPP) role in sharing product data throughout the product lifecycle. DPP and service offerings are realized using the Asset Administration Shell. Implemented in the SmartFactory-KL demonstration environment, it showcases circular process adoption and carbon footprint reduction through a service-oriented marketplace.
