Building requires first of all the extraction of earth on site. The resulting piles of earth are difficult to stock and polluting to transport. In Brussels and Flanders, 22,5 million tonnes are excavated annually. Around 75% is non-polluted, and of this amount 40% is reused in a non-circular way for road infrastructure and 60% is dumped as waste in closed quarries. BC materials closes the loop from excavation earths to circular building product. BC materials manufactures these earths locally into clay plasters, compressed earth blocks and rammed earth. These products are CO2-neutral and help to achieve a healthy interior climate. After use, these products can be given back to Earth or remanufactured into an earth building product in an infinite circular process. In the Brussels Region, we manufacture our 3 products (Kastar, Brusseleir and Brickette) in a safe way. But we also offer on-site production services in all of Belgium, to stay close to ressource extraction and to minimize transport.
