Abstract

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.

Claims

exact text as granted — not AI-modified

1 . A method of sequestering carbon dioxide, the method comprising:
 precipitating a CO 2  sequestering carbonate compound composition from an alkaline-earth-metal-containing water, wherein the carbonate compound composition comprises carbon that was released in the form of CO 2  from the combustion of fuel; and   producing a CO 2  sequestering additive comprising the carbonate compound composition; and   producing a non-cementitious composition comprising the CO 2  sequestering additive.   
     
     
         2 . The method according to  claim 1 , wherein the alkaline-earth-metal-containing water is contacted to an industrial waste stream prior to the precipitating step.
