Abstract: Provided herein are methods, apparatus, and systems for delivering carbon dioxide as a mixture of solid and gaseous carbon dioxide to a destination. In particular, provided herein are kits for retrofitting a concrete operation to supply gaseous and solid carbon dioxide to concrete in the operation, where the kit includes a conduit to connect to a source of liquid carbon dioxide and to a carbon dioxide injector, the carbon dioxide injector, a second conduit to connect with the carbon dioxide injector, a third conduit to connect with the second conduit, and an intermediate processing unit.

Abstract: Provided herein are methods and compositions for determining and reporting carbon dioxide sequestered and/or carbon dioxide avoided in operations involving concrete, including concrete raw material transport, concrete production, and concrete use.
