Tom Carter, Calera Corporation, provided an overview of the Calera
process and its potential applications to industrial processes. As
described by Mr. Carter, the Calera process, Carbonate Mineralization
via Aqueous Precipitation (CMAP), converts CO2 from industrial flue gas
streams to CO3 and  combines it with minerals to form carbonate
minerals, which can be used as aggregate, supplemental cementitious
materials, and potentially cement. The process has a capture rate for
CO2 from flue gases of 70-90%. The process also captures 95-99% of SO2
in the exhaust gas stream. Calera operated a pilot plant in California
and is currently ramping the plant to a demonstration level. The company
is also working with several electric utility companies to develop
demonstration level projects which can later be scaled up to full scale.
