Architect's Better Brick is Greener, with lower CO2 emissions
Bricks are usually fired at high temperatures in a coal-powered kiln, with laboratory-produced prototype one brick yielding 1.3 pounds of unhealthy CO2 emissions. Architecture Professor Ginger Krief Dosier of the American University of Sharjah has won a prize for growing a “Better Brick” using sand, bacteria, calcium chloride, and urea, with a new process called microbial-induced calcite precipitation (MICP).
The Next Generation Design Competition showcases the “Better Brick” on its landing page, highlighting the claim that it could reduce worldwide annual CO2 emissions by millions of tons. The laboratory-produced prototype is about the size of a Lego, but it could revolutionize the building industry, especially in countries like China and India which use outdated kilns.
]The combination of microbiology, chemistry, and design used to make the prize-winning creation took the 32-year old Professor Dosier several years of research and experimentation. She anticipates several years of further research to bring the technology from the laboratory to the manufacturing stage.
