A comprehensive analysis of process-related CO2 emissions from Iran's cement industry

Cleaner Environmental Systems
Direct emissions from the cement industry account for 7%–8% of global anthropogenic CO₂ emissions, primarily from thermal decomposition of carbonates (i.e., calcination) during clinker production. Iran ranks among the world's top ten cement producers and
