Calcination of hydrotalcite at 500[degrees]C removes its interlayer water, interlayer anions such as carbonates, and the hydroxyls to obtain a mixture of high surface area, basic metal oxides; the layer structure is destroyed (15), (16), although it may be regenerated in the presence of water containing suitable anions through the "Memory effect" (17).

The new process will not only involve a special clay-based material, called hydrotalcite, to capture the CO2, but will then use waste heat from the original industrial process itself to extract the concentrated CO2 from the hydrotalcite, after which it can be sent for utilisation or storage.
