Environmentally harmful calcination of lime is circumvented by grinding raw lime with sodium silicate. Chemists at Johannes Gutenberg University Mainz (JGU) in Germany have now developed a method that could drastically reduce CO₂ emissions from cement production in the long run. In this process, the raw lime (CaCO₃) is no longer converted ...

Emissions of PM, PM-10, and PM-2.5 occur from a number of operations in stone quarrying and processing. A substantial portion of these emissions consists of heavy particles that may settle out within the plant. As in other operations, crushed stone emission sources may be categorized as either process sources or fugitive dust sources.
