Geographically supported tool for a circular built environment. Visualization of stocks and flows of construction and demolition materials. .

The objective is to develop an integrated digital tool aimed at end users in the construction and demolition sector. The spatial material flow analysis of three construction and demolition waste streams namely wood, concrete and steel in Flanders, in 2020-2021-2022 will be visualized. Based on this, different scenarios are developed to determine possible locations and parameters for the implementation of different types of hubs for the storage, recycling and reuse of construction and demolition waste. Finally, an environmental impact assessment will be developed to evaluate the performance of different scenarios and determine the best solutions.
