"Breakthroughs in Carbon-Negative Technology: Concrete and Photobioreactors"

Researchers at Washington State University have developed a carbon-negative concrete that is nearly as strong as regular concrete by infusing regular cement with biochar, a type of charcoal made from organic waste, that had been strengthened beforehand with concrete wastewater. The biochar was able to absorb up to 23% of its weight in carbon dioxide from the air while still reaching a strength comparable to ordinary cement. The research could significantly reduce carbon emissions of the concrete industry, which is one of the most energy- and carbon-intensive of all manufacturing industries.
