The workshop aims to be a discussion forum for exploring current scientific and technological possibilities offered by sustainable materials for energy and climate purposes. Special attention will be given to new solutions based on concrete and cement-based materials. The workshop addresses complex issues with innovation potential at the interface of science, environment, technology and society. The workshop is economically supported by the Transborder Laboratory of Cooperation (LTC) Green Concrete and the projects NaturSeaPV (GA 101084348) and CSINC (GA 101223135), both funded by the European Commission.
