In order to upscale circular solutions in buildings and the construction sector in general, a concentrated research effort involving multiple actors and stakeholders is needed. This includes the development and deployment of both digital and technical solutions in building urban material databanks, digital twins, as well as demolition, decontamination and recycling and reuse of waste materials. With this in mind, the Circ-Boost project proposes to become a focal point and interaction node for different emerging technologies to foster circularity in buildings and the construction sector. The project's core consists of five pilot projects, deployed in different European regions, highlighting and demonstrating at large scale novel and integrated solutions for demolition, construction waste processing, management, and valorisation in new products. Transversal activities of digitalization will allow collaboration between the pilot projects and more efficient use of digital tools and platforms. Targeted activities are envisioned for boosting and maximising the pilot projects' commercial and business potential through effective exploitation measures. Furthermore, in order to ensure that the solutions demonstrated will actually be adopted by the industry, the project will support construction and design companies in educating and training their workforce to optimally use the new technologies as part of training activities. The Circ-Boost project will also leverage the partners' existing regional and international networks and connect with new networks, initiatives, and projects to disseminate and compare project results with a wide audience of construction stakeholders increasing the overall uptake potential of circular solutions. Finally, tailor-made communication and dissemination measures will further support the dissemination of project results with policy makers, and European-wide construction industry, as well as the promotion of the project's success.
