Production – EuLA: European Lime Association

Lime is made from indigenous limestone or chalk rock, one of the most abundant materials in the Earth''s crust. Limestone and chalk are both sedimentary rocks and are chemically known as calcium carbonate. When crushed or ground, they are widely used as aggregates and building products. As a raw material, calcium carbonate can also be processed to form lime.Reinventing Cement for a Zero-Carbon Future | DCVC2021-11-19 · It''s made by crushing limestone, chalk, and marl, and heating it to more than 1,450 °C (2,640 °F) in huge rotary kilns. This thermal decomposition process breaks down calcium carbonate into calcium oxide, or "quicklime," and carbon. The quicklime combines with raw materials such as slag and fly ash—known as "supplementary ...
