 — How this would fit with any kiln electrification plans is unknown. However, one attraction of moving to an electrical kiln, for all of the projects above, is to cut out the 40 – 50% of a cement plant's CO 2 emissions that arise from the fuel that is burnt. Taking a kiln electric also makes CO 2 capture easier.
