Converting waste into carbon-storing materials: A win-win for the environment
O.C.O Technology Limited operates a carbon capture and utilization (CCU) facility in Avonmouth, Bristol. The facility transforms industrial waste into valuable material while permanently removing CO₂ from the atmosphere.
The process utilizes Air Pollution Control Residue (APCr) – a hazardous fine-grained waste material found in flue gas residues. In the UK, APCr is usually transported over long distances for treatment and disposal at hazardous waste landfills. The project captures CO₂ and injects it into the waste material. It is then converted into artificial limestone through a chemical process.
This limestone stores carbon for more than 1,000 years while preventing the environmental damage caused by conventional limestone quarrying. The manufactured limestone can then be used in concrete, road construction, and other infrastructure projects, saving resources and reducing the demand for virgin aggregates.

Carbon capture and utilisation: Turning emissions into valuable resources
Reducing greenhouse gas emissions is essential to mitigate climate change. But many industrial processes, like cement, lime, or glass manufacturing, are not free of emissions. Thus, innovative approaches aim to remove unavoidable emissions from the atmosphere or capture emissions at the source of heavy industries.
Carbon capture and utilisation (CCU) captures carbon emissions from industrial processes and uses them as feedstock for other operations. The captured CO2 can be used to produce concrete, fuel, chemicals, or plastics. Depending on the intended use, the CO2 is either temporarily or permanently sequestered, which has a positive effect on the climate because they have permanence from several decades to over 1,000 years.
The project aims to contribute to these United Nations’ Sustainable Development Goals (SDGs).
