The Gent Waste Brick was designed by London-based practice Carmody Groarke in partnership with materials designers BC Materials and Local Works Studio. Together, they developed an energy-saving method that takes ground construction waste materials, mainly crushed concrete, masonry, and glass, from demolished buildings and infuses lime to form dry-cured bricks. This approach utilizes local materials rather than extracting clay or importing mass-produced bricks from elsewhere. As reported by Fast Company, the materials were collected mostly from within five miles of the museum. 

The bricks are formed in a shipping container-sized mobile processor and then dry cure for 60 days, a much less energy-intensive process than traditional brick production. As a result, they will reportedly produce a third of the amount of carbon dioxide over a 60-year lifespan than a conventional brick. For the museum expansion, the Gent Waste Bricks will be used on the museum's facade, which is expected to complete in 2024.
