The building sector is always looking for new sustainable material solutions to meet the various market needs. On the occasion of Made Expo in Milan, the arch. Marco Capellini had the pleasure to meet some companies to discuss innovative and circular solutions. It was an excellent opportunity to identify solutions of circular materials to be carried out, starting from the creation of new “recipes” and from pre-consumer waste or demolition waste. Research projects that look at the circularity of materials, performance and aesthetic aspects for flooring, cladding elements and insulation products developed in collaboration with Matrec.
