ICARUS will upcycle waste material resources of most selected process industries (covering minerals, cement, ceramic, non-ferrous metals, steel, water, pulp&paper and chemical ones) to achieve circular and sustainable process industries overcoming their final application in construction sector. This project will accelerate the process industry uptake and contributing towards the developed education and skills activities and outcomes in this area as well as linking all value chain from industrial players recyclers, public authorities, and standardisation actors. ICARUS tackles resources usage in the construction sector (housing and infrastructure), accounting for 50% of the total material extraction, and being responsible for more than 35% of waste streams in the EU. Furthermore, the circular economy in the sector is still at a very early stage, with an estimated level of circularity for the EU of 12.4% material use rate in the year 2021. ICARUS approach aims to give technological support to stakeholders of energy-intensive and construction industries as key players for the transition to a more green and digital processes industries supported by standardization aspects to promote values and a resilient, green and digital Single Market and business models including co-creation and co-design to successful market implementation. ICARUS will represent a breakthrough in the research and demonstration of new technologies to upgrade Secondary Raw Materials ensuring similar quality as primary raw materials, of three waste streams to improve circular economy principles in several intensive industries with its implementation in the construction sector, to improve circular economy principles in P4P process industries. These new technologies will be demonstrated throughout 3 demo cases: 1-Upcycling of Lithium Aluminosilicate Residue;2-Upcycling of SRMs from urban waste cellulose;3-Upcycling of steelmaking slags via Carbon Capture and Storage .
