With three tonnes used for every man, woman, and child on the planet each year, concrete is the second most used material in world, exceeded only by water in terms of quantities consumed by humanity.
Made from a mixture of clinker and gypsum, cement is the glue that binds the aggregates together to form this essential component of the modern construction industry.
C-Capture’s unique carbon capture technology
C-Capture’s unique carbon capture technology can be retrofitted to existing cement kilns, or designed into new kilns, to capture the carbon emissions from this globally prevalent industry and mitigate its impact on the climate crisis.
Emissions from concrete manufacture
Because of the way clinker is manufactured, using coal or natural gas fired kilns to intensely heat limestone (calcium carbonate, CaCO3), driving off carbon dioxide to form lime (calcium oxide, CaO), CO2 emissions are an unavoidable fact of this industry.
The 4 Gt of cement produced each year globally are responsible for 1.5-2.2 Gt of CO2emissions, approximately 5% of the global total. The World Business Council for Sustainable Development estimates that by 2050, the cement industry must prevent 0.5 Gt of CO2 emissions per year for us to stay on a path to 2 °C or less warming above pre-industrial levels.
