Washington State University researchers developed a carbon-negative concrete formula by infusing cement with biochar, reducing the industry’s carbon emissions.
This environmentally friendly concrete reaches strength comparable to regular cement while absorbing up to 23% of its weight in CO2 from the air.
In a proof-of-concept work, the researchers at Washington State University infused standard cement with biochar, a type of charcoal produced from organic waste, which had previously been fortified with concrete wastewater.
