From page 229...
... Carbon dioxide removal The objective is large-scale removal of carbon dioxide from the atmosphere. Carbon dioxide removal approaches considered by the committee are coastal and land ecosystem management, accelerated weathering, bioenergy with carbon capture, direct air capture, and geologic sequestration.

... Gaseous carbon waste Carbon dioxide, methane, or biogas that is present in a waste gas stream. streams Life-cycle assessment A technique used to catalog energy, water, and materials (e.g., chemicals, metals)

From page 231...
... Mineral carbonation Formation of carbonates by contacting alkaline solids, often in an aqueous suspension, with carbon dioxide in a fluid state. In the context of this study, mineral carbonation refers to forming a useful product, rather than related chemical processes to sequester carbon in the form of natural carbonates.
