On June 2020, the European Project ICEBERG was officially launched. The project aims to develop and demonstrate novel cost-effective circular smart solutions for an upgraded recovery of secondary building raw materials along the entire circular value chain: from end-of-life building materials (EBM) to new building products prepared for circularity, resource-efficiency and containing 30wt% to 100wt% of high-purity (>92%) recycled content. This will be undertaken through 6 pilot circular case studies, covering building materials accounting for more than 85% by weight of the European built environment.
