Constructing with Carbon

Carbon dioxide from industrial flue gas is converted to carbonate by combining CO2-containing gas with a water-based capture solution, thereby avoiding costly purification methods involved in other carbon capture methods. The carbonated solutions formed are then applied to coat particles and form limestone building materials, comparable to the natural formation of limestone in the ocean. Materials sold by the company include aggregates, sack concrete, and roofing granules.
