DescriptionCarbon To Stone is developing a new approach that couples Direct Air Capture (DAC) with mineralization. Conventional DAC processes use heat or pressure changes to regenerate solvents reacting with CO₂, resulting in high energy use. Carbon To Stone chemically regenerates the solvent by reacting it with alkaline material such as steel slag, fly ash, or mine tailings to produce carbonates that could be used for alternative cements. This approach reduces both the energy and the cost required for the same tonnage of CO₂ captured.
