Deep decarbonisation within the process. The formation of carbon dioxide during the calcination reaction is unavoidable and can account for up to 65% of carbon dioxide emissions from cement production. "Capture of the carbon dioxide is an option and retrofitting carbon capture equipment to cement plants is conceivable," says d'Hubert.
Cement production is not only a source of combustion-related CO2 emissions, but it is also one of the largest sources of industrial process-related emissions in the United States. Between 1990 and 2001, U.S. process-related emissions increased 24%, …
