CO2 whose atmospheric concentration has risen from pre-industrial levels of 280 ppm to 380 ppm in 2005 is the most important greenhouse gas (GHG), being responsible for about two-thirds of the enhanced greenhouse effect. Increasing public concern has led to the development of a number of carbon sequestration processes for mitigating CO2. Mineral carbonation is an attractive method for the removal of CO2 as it results in permanent storage of CO2 as mineral carbonates that are environmentally benign. This technology could contribute significantly to CO2 sequestration in the proximity of the emission source, without the need of storing the gas into a geological reservoir. Usage of industrial solid alkaline waste materials as a raw material is a promising strategy in this technology.

The study will reveal the potential capacity of the identified industrial alkaline solid residue in sequestering CO2. The overall performance of the identified residue for the sequestration technology will be discussed in terms of its carbon capture capacity, utility and economy.
