A process to capture and  convert gaseous carbon dioxide gas into a mineralized solid form, bound to mineral rocks such as Serpentine. Other feedstock from waste materials have also shown great promise for mineralisation. In this process, the carbon dioxide is captured then converted into a carbonate in the feedstock, which is thermodynamically more stable and inert. Once bound, the carbon dioxide is not susceptible to re-emission into the atmosphere unless subjected to extreme conditions.

Our Innovation

CO2 mineralization offers Singapore the ability to effectively capture and repurpose waste CO2 from incineration plants, enabling net carbon abatement. Additionally, the technology also produces an alternative sand, which could supplement Singapore’s heavy need to import sand for national development. Abt 90% of sand is imported from our neighbouring countries.

In summary, CO2 mineralization as a CCU technology could be considered as a part of a suite of technologies for Singapore to achieve this goal, while contributing to national sustainability and development targets.

Potential Applications

The applications for this technology would be usable for a wide range of industries with a focus on the manufacturing and constructions sectors. This technology would be used for mining and coal power generation. As it creates alternative sand, this technology could also be applied to cement and steel production, metal refineries, various other coal to gas plants. 

Our Value Proposition

This innovation presents a green sustainable solution to reduction of CO2 level. Not only does it help Singapore achieve its sustainability goals and decrease CO2 levels, it creates green building materials that can also be used to create other valuable end-products. Overall this technology provides a solution to generating higher value propositions for Singapore to meet both its development and sustainability targets.
