A construction project using CO2 negative facing bricks

A CO2 negative facing brick by brick manufacturer Vandersanden is being used in its first construction project, which should save 42.500 kg CO2.

Called Pirrouet, the facing brick by Vandersanden is made of up to 80% of the raw materials come from residual flows from the steel industry. It also uses CO2 as a raw material to harden the stones. This means CO2 is absorbed rather than generated, which makes the bricks CO2 negative.

The facing brick is used for a new construction project, called ‘Groen Nobelhorst’ in Almere, in the Netherlands. Heutink Group and Heren5 Architects are building sixty sustainable homes there. A total of 320,000 Pirrouet facing bricks are used for the project. Together they absorb 42,500 kg of CO2. Vandersanden claims the CO2 is not released at the end of the bricks’ lifespan.
