Emissions from the Cement Industry. May 09, 2012· The direct emissions of cement occur through a stone process called calcination. Calcination occurs when limestone, which is made of calcium carbonate, is heated, breaking down into calcium oxide and CO 2.
Cement Plants: Cement from Waste Materials
Until rotary lime kilns were developed, the resulting calcium carbonate was too fine to re-burn. Plants using carbonate waste began to proliferate after 1890, the imperatives driving this being typified by Crosfields, who had been prosecuted for dumping their waste in the Mersey.

Calcium looping - Wikipedia
Calcium looping (CaL), or the regenerative calcium cycle (RCC), is a second-generation carbon capture technology. It is the most developed form of carbonate looping, where a metal (M) is reversibly reacted between its carbonate form (MCO 3) and its oxide form (MO) to separate carbon dioxide from other gases coming from either power generation or an industrial plant.
