This demonstration focuses on illustrating a circular value flow where flat glass from existing buildings is recovered, processed, and used to produce new flat glass, ultimately reinstalled as a window component. The aim is to show how both the physical movement of materials and the flow of information are essential for enabling circularity. A key aspect of circular physical flows is the timely exchange of accurate data. Each actor in the value chain must be able to share and access relevant information at the right moment. In this context, the demonstration highlights how material can be traced both physically and digitally across different steps in the value chain. The demonstration also shows how Circular Value Flow Planning (CVFP), along with the required digital capabilities, is integrated into the CP-IM platform. This includes using data for circularity assessments and strategic material planning.
