Abstract:
Compositions comprising synthetic rock, e.g., aggregate, and methods of producing and using them are provided. The rock, e.g., aggregate, contains CO2 and/or other components of an industrial waste stream. The CO2 may be in the form of divalent cation carbonates, e.g., magnesium and calcium carbonates. Aspects of the invention include contacting a CO2 containing gaseous stream with a water to dissolve CO2, and placing the water under precipitation conditions sufficient to produce a carbonate containing precipitate product, e.g., a divalent cation carbonate.

Abstract:
Aspects of the invention include methods of removing carbon dioxide (CO2) from a CO2 containing gas. In some instances, the methods include contacting CO2 containing gas with a bicarbonate buffered aqueous medium under conditions sufficient to produce a bicarbonate rich product. Where desired, the resultant bicarbonate rich product or a component thereof may then be stored or further processed, e.g., combined with a divalent alkaline earth metal cation, under conditions sufficient to produce a solid carbonate composition. Aspects of the invention further include systems for practicing the methods, as well as products produced by the methods.
Abstract:
Provided are methods for sequestering carbon dioxide utilizing magnesium hydroxide. A recovery method and system for recovering a gaseous component is provided. Methods and systems may utilize an alkaline component produced by thermal activation of magnesium hydroxide. Compositions of sequestered carbon dioxide comprising magnesium carbonate or magnesium bicarbonate are provided.

Abstract:
A system and method of generating and trading a CO2 commodity that is correlated to a quantified amount of CO2 sequestered in a CO2 sequestering product comprising a carbonate and/or a bicarbonate. The tradable commodity can be purchased or sold for use in managing CO2 emissions.
Abstract:
Formed building materials comprising a sequestered CO2 are provided. The building materials of the invention include a composition comprising a carbonate/bicarbonate component. Additional aspects of the invention include methods of making and using the formed building materials.
