This demonstration focuses on different inventory methods for identifying flat glass recycling and finding a method for transferring information between different software/programs and actors. This to secure that 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 the inventory with a structured methodology and dataset enable the physical movement of components and the flow of information for enabling circular material flows. 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.
