BIOENGINEERED BRICKS
Just add bacteria….
“There are over 1.3 trillion bricks manufactured each year worldwide, and over 10% are made by hand in coal-fired ovens. On average, the baking process emits 1.4 pounds of carbon per brick - more than the world’s entire aviation fleet. In countries like India and China, outdated coal-fired brick kilns consume more energy, emit more carbon, and produce great quantities of particulate air pollution. Dosier’s process replaces baking with simple mixing, and because it is low-tech (apart from the production of the bacterial activate), can be done onsite in localities without modern infrastructure. The process uses no heat at all:mixing sand and non-pathogenic bacteria (sporosar) and putting the mixture into molds. The bacteria induce calcite precipitation in the sand and yield bricks with sandstone-like properties. If biomanufactured bricks replaced each new brick on the planet, it would save nearly 800 million tons of CO2 annually.”
