The problem
Concrete accounts for 8% of global CO2 emissions.
Approximately 4 billion tonnes of cement are produced annually which creates 3 billion tonnes of CO2 per year, accounting for 8% of global CO2 emissions.
Presently, the concrete industry is relying on waste by-products of other carbon intensive industries to reduce embodied carbon through using less traditional cement – these are not viable long-term solutions.
C4C exists to provide a solution to this, turning an emission problem into an emission solution.

the solution
Utilise CO2 from flue gas.
Strengthen Concrete.
Reduce Costs.
Strengthen Concrete.
Reduce Costs.
C4C has developed a novel technology that is tailored to the needs of the industry. Helping industry emitters to utilise the CO2 from their flue gas and helping concrete producers reduce their cement and embodied emissions of their concrete - win-win all round
By exploiting the full natural potential of concrete for the permanent storage of CO2, our technology is set to become the global standard for CO2 sequestration and embodied carbon reduction for ready-mix and pre-cast concrete.

No other technology has the capability to utilise flue gas and abundant calcium waste to produce a high value product that makes concrete stronger, cheaper and cleaner. Our world leading concrete chemistry expertise enables us to help producers maximise the benefits our product in their mixes and meet their needs.

the technology
Making materials from CO2 - creating lower cost and lower emission concrete
Our technology takes raw flue gas from cement and lime production plants, combining it with abundant calcium waste sources to produce a reactive calcium carbonate material that permanently sequesters CO2 in concrete - making concrete stronger, more durable and with less cement.
There is no change to concrete production processes, as the C4C material is mixed in fresh concrete alongside everything component material. This approach permanently locks up CO2 in concrete, helping cement producers solve their flue gas problem and helping concrete producers solve their cement problem.
Our technology makes concrete stronger and cheaper, whilst reducing embodied carbon. Providing a revolutionary solution to decarbonise the construction industry. Our mission is to help create more sustainable built environments to facilitate the lives of people around the world and help cities transition to net-zero and beyond.

THE GOAL
Mitigate 2 Billion Tonnes Of CO2 by 2040.
With both CO2 sequestration and cement reduction, we dramatically reduce the carbon footprint of concrete, with our technologies under development having the potential to make concrete net-negative.
