The plant management investigated the origin of the emissions to be able to predict CO peaks and anticipate potential issues ahead of time. It turned out that the quarry was the main source of CO emissions. The total organic carbon (TOC) content of the limestone mined correlated well with the levels of CO emissions.

Step 1: Quarry. For its raw materials, cement manufacturing uses minerals containing the four essential elements for its creation: calcium, silicon, aluminum, and iron. Most plants rely on a nearby quarry for limestone. The most common combination of ingredients is limestone coupled with much smaller quantities of clay and sand.
