Mineral Carbonation

Mineral carbonation is employed to capture and store CO<sub>2</sub> from various sources. There exist several potential end-uses for the produced carbonate minerals, particularly in the construction industry.


Mineral carbonation combines the steps of carbon capture and storage by reacting CO2 with alkaline materials to produce stable carbonate minerals with no risk of leakage under practical conditions. As depicted in the above figure, this technology can be applied to various sources of CO2, and there exist several potential end-uses for the produced carbonate minerals, particularly in the construction industry.

Our group is exciting about the prospects of this technology, and we aim our investigative approach at multiple levels:

Research Topics
  1. Process development and optimization for alkaline mine tailings
  2. Mapping for the co-location of CO2 and alkalinity sources to reveal promising geographical areas
  3. Investigation of product utilization through evaluation of material properties and analysis of CO2 avoidance potential
  4. Techno-economic analysis of current and proposed carbonation processes
