The proposal focuses on constructing new structures by reusing large fragments of mineral waste from urban pavements, mainly asphalt and concrete, without the need for prior separation or transformation. The proposed system employs a simple and cost-effective process that adapts to existing infrastructure and enables the production of large-scale building elements such as walls or retaining structures. This approach minimises material handling while significantly reducing the carbon footprint. The result is a modular, prefabricated solution that paves the way for a more circular and sustainable construction model.
