1. A method of sequestering carbon dioxide from a cement and production facility comprising
i) treating flue gas comprising carbon dioxide from a cement manufacturing process of the cement production facility to render the carbon dioxide transportable, wherein the flue gas comprises flue gas from a preheater exhaust gas at a discharge of an exhaust fan;
ii) transporting the carbon dioxide to a concrete production facility; and
iii) treating a cement binder mix at the concrete production facility with the carbon dioxide to sequester the carbon dioxide in a concrete product, wherein the cement binder mix comprises cement produced at the cement production facility.
