Bacteria Used to Manufacture Bricks With Zero Emissions
A relatively new company founded by Ginger Krieg Dosier known as bioMASON is now able to produce bricks without the need to fire them in a kiln for several days, a process that the company says produces 800 million tons of carbon dioxide emissions each year.
Rather than being fire hardened, these bricks include a special type of bacteria that produces calcium carbonate to harden the sand and aggregate in the mixture. The specific hardness can be controlled for various projects by the amount of water and nutrients fed to the microorganisms. The finished product is called biocement, and it not only eliminates carbon emissions but also the need for fuel, which saves both energy and money.
