Carbon Dioxide Capture in Cement Manufacturing

Market Overview:

The US cement industry produces over 41million metric tons (MMT) of process-related CO2 per year1. That total excludes the CO2 released from the burning of fossil fuel to heat the process. This invention provides a method of capturing much of that CO2 for sale or storage.

Using several possible methods, the CO2 may be captured and reintroduced into the system before being captured again and extracted from the system. The initial reuse of the gas influences the production of alite and belite. The alite to belite ratio influences the curing and strength properties of the concrete. Using the CO2 in this way allows the cement manufacturer to provide customization and value to customers while significantly reducing greenhouse gas emissions.


· Cement production


· Captures CO2

· Creates hydrating belite and alite, which control early and late cure strengths of concrete

· CO2 is clean and sufficient for sale or storage
