Materials
The CO2nstruct project focuses on six carbon-intensive materials. These were further subdivided into 14 main subclasses that are investigated throughout the project. The materials are here briefly described with current circular economy practices introduced for one selected subclass after Lima et al. (2024). The text is based on the publication from CO2NSTRUCT “Mapping circular economy practices for steel, cement, glass, brick, insulation and wood – A review for climate mitigation modeling”, which can be found here.
