Laying the foundation for zero-carbon cement
Another efficiency lever is advanced analytics. One European cement producer achieved 6 percent fuel savings by creating self-learning models of a kiln's heat profile and optimizing the shape and intensity of the kiln flame. Future cement plants could leapfrog competitors by combining digital technology and more sustainable operations.
