The manufacture of concrete, one of the most energy intensive materials, uses limestone shale converted into Portland cement through high-heat processes. Both concrete and clay manufacturing include energy intensive processes for raw material extraction, transportation, and fuel sources for heating kilns. 40% of global CO2 emissions are linked to the construction industry. An innovative start-up in North Caroline, bioMASON that uses a bio-chemical process to manufacture bricks could increase the sustainability of the construction sector.
bioMASON employs bacteria to “grow” a durable cement in ambient temperatures to manufacture biological cement-based masonry building materials. This process simply eliminates the need for firing by replacing the curing/hardening process with the formation of biologically controlled structural cement.
