SUM4Re proposes a comprehensive approach to creating materials banks from the built environment by combining urban mining and technologies for automated on-site data acquisition and building materials identification and asset components. The project aims to achieve nine objectives, including developing a traceability system for building materials, developing a holistic methodological framework for assessing circular use of construction products, and developing on-site and off-site smart digital solutions to identify construction entities and analyse their properties. The relevance of the project lies in the need to address the increasing generation of construction and demolition waste, which is the largest waste stream in the EU, as well as the problems associated with CO2 emissions and climate change.
