stonesis

Stonesis is a mineral composite developed from the reuse of waste generated in the marble industrial process. The material is the result of practical and experimental research conducted in collaboration between the University of Porto and TCC Whitestone, aiming to explore new possibilities for valorizing by-products from the natural stone industry.

Its formulation combines fine marble powder, cutting slurry, and mineral fragments, bound by a controlled cementitious binder. The proportion between these components was carefully studied to ensure mechanical strength, dimensional stability, and a high-quality surface finish, while maintaining a low environmental impact.

The development process of Stonesis involved multiple testing stages, from density and moisture analyses to molding, pigmentation, and CNC machining trials. The research also considered aesthetic and tactile aspects, allowing the creation of different textures and tones depending on the type of residue used, such as travertine, Moleanos, and other Portuguese marbles.

More than an alternative material, Stonesis represents a circular design methodology applied to industry. It demonstrates that it is possible to generate high-value products from waste, bridging academic research and real-world production, and promoting a more sustainable and responsible manufacturing model.
