hëmpcrete is a material mixed with a binder that hardens it into a solid in the form of blocks and panels. Made from the dried woody core of hëmp stalks and a lime-based binder, hëmpcrete can be cast just like concrete. But unlike concrete and its binding cement, which accounts for about 8% of human-generated carbon dioxide emissions annually, hëmpcrete actually sequesters CO2. According to a recent study, hëmpcrete can sequester 307 kilograms of CO2 per cubic meter (19 pounds per cubic foot), roughly the equivalent of the annual carbon emissions of three refrigerators.
