NON-CEMENTITIOUS COMPOSITIONS COMPRISING CO2 SEQUESTERING ADDITIVES
Non-cementitious CO 2 sequestering compositions are provided. The compositions of the invention include a CO 2 sequestering additive, e.g., a CO 2 sequestering carbonate composition. Additional aspects of the invention include methods of making and using the non-cementitious CO 2 sequestering compositions.
1 - 2 . (canceled)
3 . A method of forming a non-cementitious composition, comprising:
precipitating a CO 2 sequestering composition by contacting CO 2 released from combustion of fuel with an aqueous composition, wherein said CO 2 sequestering composition comprises carbon from said CO 2 ; and
producing a non-cementitious composition comprising said CO 2 sequestering composition in an amount of 1% by weight or more.
4 . The method of claim 3 , wherein said precipitating comprises removing protons from said aqueous composition using a proton-removing agent.
5 . The method of claim 4 , wherein said proton-removing agent comprises naturally occurring proton-removing agent, synthetic proton-removing agent, microorganism, fungi, man-made waste stream, or any combination thereof.
6 . The method of claim 4 , further comprising forming said proton-removing agent by an electrochemical process.
7 . The method of claim 6 , further comprising producing hydroxide at a cathode and an acid at an anode in said electrochemical process.
8 . The method of claim 7 , wherein said acid is hydrochloric acid and said method further comprises producing vinyl chloride monomer from said hydrochloric acid.
9 . The method of claim 8 , further comprising producing poly(vinyl chloride) from said vinyl chloride monomer.
