BC materials transforms excavated earth of construction sites into building materials.As a first step, building requires the extraction of earth on site, which is hard to stock and challenging to transport. Belgium for example excavates around 37 million tons per year, and 70% of it is being dumped or landfilled as waste. Building in itself is one of the most polluting human activities, being responsible for 30% of carbon emissions, air pollution, material resource use, and 75% of total waste production, while only bringing in an estimated 4% of GDP.BC materials wants to help contractors, architects and clients to achieve their climate targets, and improve the indoor living quality of their projects. We transform pure earth of construction sites to local building materials such as clay plasters, compressed earth blocks and rammed earth for walls and floors. These products are circular, carbon neutral, healthy and possess minimal grey energy.
