About the project

CIRC-BOOST is a 4-year project, funded under the Horizon Europe Programme, that focuses on testing and upscaling circular solutions in buildings and the construction sector through five pilot projects deployed in different European regions. The pilots will demonstrate, at large-scale, novel and integrated solutions for demolition, construction waste processing, management, and valorisation in new products.
