The construction industry is characterized as one of the most polluting on the planet. Construction and demolition waste (CDW) represent about one-third of all waste generated globally. "Fragments of the Past" is a material research project aimed at valorizing building waste from the perspective of upcycling, applied in the development of decorative objects. Developed from CDW (glass, stones, bricks, concrete), combined with the dust produced from cutting granite stones and a small percentage of cement, the circular material seeks to revive the history behind construction waste.
