O.C.O are experts in the application of Accelerated Carbonation Technology (ACT) for carbon capture. ACT is a genuine Carbon Capture and utilisation process. Carbon dioxide is permanently captured as stable carbonate minerals. We are able to valorise thermal residues as construction products. In the UK, O.C.O Technology has three commercially operating plants producing carbon negative aggregate, which is being supplied to the construction industry as a sustainable construction material. Our aggregate is named M-LS. M for Manufactured, LS for LimeStone. M-LS is Carbon Negative. More CO₂ is permanently captured during the process than used in its manufacture. Accelerated Carbonation Technology (ACT) is an effective waste treatment process that stabilises contaminants, enhances the handling of the wastes, and can reduce disposal costs. A multitude of wastes can be readily treated and rendered less hazardous using ACT.
