The construction sector is recognized as one of the most polluting sectors in the world, with substantial environmental, social and economic impacts throughout its production process. Construction and demolition waste (CDW), which accounts for around a third of global waste, is a significant challenge, especially in urban areas.

“Fragments of the Past” is a circular material developed by designer Mayra Deberg as part of a materials research project at the Faculty of Engineering of the University of Porto. This material is made from recycled CDW combined with granite dust and a cement-based binder, offering a contemporary reinterpretation of the traditional terrazzo technique. By reusing locally sourced waste, it significantly reduces the need for virgin aggregates, promoting a sustainable approach to the use of resources.

The material’s flexibility allows it to be molded into various shapes, making it ideal for decorative objects and furniture applications.
