CREW Carbon specializes in removing greenhouse gas emissions from wastewater by utilizing engineered enhanced weathering. Their unique solution involves adding natural minerals, such as calcium carbonate, to wastewater, which reacts with CO2 to form stable bicarbonate ions. This process not only improves pH and alkalinity control safely and cost-effectively but also permanently captures carbon dioxide within existing treatment systems. The effectiveness of CREW Carbon’s technology has been proven by capturing thousands of tons of CO2 annually. Their patented technology, developed at Yale University, is protected under U.S. Patent No. US11,938,445B2.
