The average clinker production plant size has been steadily increasing over the years, and now construction has begun on what will be the largest single clinker production line in the world. At 12,000 metric tons per day clinker and 4 million metric tons annual cement capacity, this massive greenfield plant is being built by Holcim in the United States along the Mississippi River in Ste. Genevieve County, Missouri. The uniqueness of this undertaking is not only the size, but also the strict efficiency goals and environmental regulations that will apply to the site development, construction, and operation. Preliminary evaluation of the Ste. Genevieve project began in the late 1990's, and Holcim ultimately underwent a six year process of reviews and permits involving eight federal and state regulatory agencies. With all permits finally in hand, Holcim awarded a contract in early 2006 to one supplier for all the main and auxiliary mechanical and electrical equipment as well as engineering services, training, and commissioning. The focal point of the plant will be the single pyroprocess system with new generation clinker cooler and in-line preheater with low NOx and CO calciner. Furthermore, the supply of four (4) vertical roller mills has also reinforced this solution as the market standard for finish cement grinding. Because the plant will meet emission limits among the lowest permitted for any cement plant in the United States and the world, any environmental impact will be minimized. In addition, approximately 2200 acres (55% of the total property's acreage) will be preserved in its natural condition for the entire life of the plant. The success of the Ste. Genevieve project is based on the strong partnership and open relationship that has been developed between Holcim and the supplier. Start-up of the plant is scheduled for 2009. With a foundation of a sound technical solution and combined worldwide resources, this extraordinary project will no doubt be a source of pride for all parties involved.
