Carbon Negative Bricks – Pirrouet

Instead of being fired in kilns, Pirouett bricks from Vandersanden are cured in airtight, CO2-filled climate chambers for 48 hours. Using waste products from the steel industry and just 20% primary raw materials, the bricks are made through a process whereby carbon dioxide is permanently bound to calcium. Per metric ton of bricks, 60 kg of CO2 is captured and stored.
