This concrete can eat carbon emissions
Concrete is responsible for more than four percent of all global CO2 emissions. In the race to find alternatives, some companies are using it to sequester CO2 instead
According to the Paris agreement, carbon emissions from cement production need to fall by at least 16 percent by 2030 for the world to reach its target of keeping global warming within the limit of 1.5C and well below 2C. “Ordinary Portland cement-based concrete products consume around 2.6 trillion liters of water annually,” says Solidia CEO Bryan Kalbfleisch, referring to the type of cement most commonly used in construction. “As soon as the product is approved with ASTM [the American Society for Testing and Materials, the international regulatory body] and other governing code associations, we can quickly scale within this enormous portion of the market,” Kalbfleisch says.
