Carmody Groarke develops bricks made of city waste for museum facade in Ghent, Belgium

Waste from the city of Ghent, Belgium, is being turned into the building blocks of a major cultural institution. For a renovation and expansion of the Design Museum Gent, an innovative new recycling process is turning old bits of broken concrete and glass into the bricks that will cover the museum’s exterior.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 co...
