The construction industry produces approximately 40% of the global CO2 emissions. Within this enormous amount, about 800 million tons of global CO2 emissions per year account for the traditional clay brick manufacturing. This is more than the global aviation fleet! The low-tech methods used for brick production often rely on hazardous materials for fuel. More modern methods are inherently cleaner but still require a firing process which consumes large amounts of fossil fuels. Finding a more sustainable brick manufacturing solution therefore has a huge positive environmental impact.
bioMASON grows biocement utilizing microorganisms
US-based startup bioMASON has developed a technology that does not require high heat to manufacture clay and concrete construction products. Instead it uses mine dust, recycled mass or plain sand as aggregate, natural bacteria for inducing cement formation combined with feedstocks nutrients and minerals extracted from natural waste streams. bioMASON’s founder and CEO, Ginger Dosier, got inspired by the very hard cementitious materials found in coral. Where the construction industry requires massive amounts of fossil fuels to manufacture cement, mother nature uses ambient sea temperature, low energy and minimal material input to produce the same result.
How will this impact the construction industry?
bioMASON’s goal is to incorporate her technology in the existing production lines of brick manufacturers. Moreover, drawing the parallel with how coral is able to locally source the necessary materials, bioMASON would like to capitalize on the benefits of distributed manufacturing. By setting up closed-loop production modules at construction sites, builders can utilize indigenous raw materials to produce biocement and bricks creating zero waste.
