Study of Energy Use and CO2 Emissions in the Manufacturing of Clinker and Cement

Cement is one of the most widely used materials in construction. This study presents a process-wise evaluation of energy use and CO2 emissions for clinker, Ordinary Portland Cement (OPC) and Portland Pozzolana Cement (PPC) using the principles of life-cycle assessment. Two cement plants located in India are considered as typical case studies. The gate-to-gate system boundary condition is considered. The energy use for clinker is found to be 3990...
