An interactive visualization tool for circular economy and building materials recovery

Construction materials represent the largest material stock accumulated in modern society. The unprecedented growth of material stock is directly linked to high resource and energy consumption, demolition of waste discharges, and is correlated with the increased embodied energy and the associated CO2 emissions. Governments in Europe are looking for possibilities in the construction sector to replace raw materials with secondary resources through reuse and recycling by transitioning to a circular economy. But for cities, the practical aspects of the initiative remain challenging in multiple aspects. This work aims to introduce a visualization tool for built environment material stocks and flows to support circularity enabling recycling and reuse of these materials in existing buildings and infrastructures. The recovery of building materials in the circular economy requires map-based visualization tools through which statistical analyses can be made on buildings or groups of buildings. For this, it is necessary that the visualization tool contains API links to real building inventory data from local public authorities and advanced functions of real-time analysis of the attribute table and geospatial data.
