    Jan 25, 2022 Cement is typically produced by mining, grinding, and heating limestone in industrial kilns to temperatures as high as 2,820 degrees Fahrenheit (1,550 degrees Celsius). The process alters the rock’s chemistry and creates “clinker” — the basic component in nearly all types of cement — but also generates large quantities of carbon dioxide
