Cover Story: The environmental assessment of metakaolin as a supplementary cementitious material (SCM) through an integrated production process simulation and life cycle assessment (LCA) approach is addressed. Process simulation models that reproduce the basic stages of metakaolin production have been developed. The effect of various operational parameters and scenarios on the process heat demand and CO2 emissions is examined. Process simulation results are used as inputs in the LCA, along with upstream literature data (cradle-to-gate approach). LCA results highlight the influence of process temperature, kaolin moisture, exhaust gas recirculation, and various fuels’ combustion (to provide kiln heat requirements) to the life cycle GWP (global warming potential—GWP(100)).
