Abstract

Non-cementitious CO₂ sequestering compositions are provided. The compositions of the invention include a CO₂ sequestering additive, e.g., a CO₂ sequestering carbonate composition. Additional aspects of the invention include methods of making and using the non-cementitious CO₂ sequestering compositions.

Claims

1. A non-cementitious composition comprising a CO₂ sequestering additive, wherein the CO₂ sequestering additive comprises carbon that was released in the form of CO₂ from the combustion of fuel.

2. The non-cementitious composition according to claim 1, wherein the CO₂ sequestering additive is a carbonate compound composition.

3. The non-cementitious composition according to claim 2, wherein the carbonate compound composition comprises a precipitate from an alkaline-earth metal-containing water.

4. The non-cementitious composition according to claim 3, wherein the alkaline-earth metal-containing water comprises CO₂ derived from an industrial waste stream.

5. The non-cementitious composition of claim 1, wherein the composition is a paper product, polymeric product, lubricant, adhesive, rubber, chalk, asphalt product, paint, abrasive for paint removal, personal care product, ingestible product, animal ingestible product, agricultural product or environmental remediation product.

6-27. -27. (canceled)

28. A method of producing a non-cementitious composition, the method comprising:

obtaining a CO₂ sequestering additive, wherein the CO₂ sequestering additive comprises carbon that was released in the form of CO₂ from the combustion of fuel; and

producing a non-cementitious composition comprising the CO₂ sequestering additive.

29. The method according to claim 28, wherein the CO₂ sequestering additive is a carbonate compound composition.

30. The method according to claim 29, wherein the carbonate compound composition comprises a precipitate from an alkaline-earth metal-containing water.

31. The method according to claim 30, wherein the alkaline-earth metal containing water comprises CO₂ derived from an industrial waste stream.

32. The method of claim 28, wherein the non-cementitious composition is a paper product, polymeric product, lubricant, adhesive, rubber, chalk, asphalt product, paint, abrasive for paint removal, personal care product, ingestible product, animal ingestible product, agricultural product, soil amendment product, pesticide or environmental remediation product.

33-54. -54. (canceled)

55. A method of sequestering carbon dioxide, the method comprising:

precipitating a CO₂ 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 CO₂ from the combustion of fuel; and

producing a CO₂ sequestering additive comprising the carbonate compound composition; and

producing a non-cementitious composition comprising the CO₂ sequestering additive.

56. The method according to claim 55, wherein the alkaline-earth-metal-containing water is contacted to an industrial waste stream prior to the precipitating step.
