Revolutionary Carbon-Negative Concrete Invented to Reduce CO2 Emissions.
Researchers at Washington State University have developed a 'carbon-negative' concrete that removes up to 23% of its weight in carbon dioxide from the air during its formation by using 30% biochar, a type of charcoal made from organic waste, mixed with concrete wastewater. The new formula maintains a similar strength to ordinary cement and the carbon dioxide remains sequestered inside the concrete for its lifespan. The team hopes the invention will significantly reduce carbon emissions from the concrete industry and is now working to patent and commercialize the technology.
