| Abstract | Cement manufacturing is a critically important industry in the United States and throughout the world. In 2006, U.S. cement plants produced 99.8 million metric tons of cement. Worldwide production accounted for about 2.5 billion metric tons. As with most large manufacturing industries, by-product materials are generated. These industrial by-product and waste materials must be managed responsibly to insure a clean and safe environment. Cement kiln dust (CKD) is a significant by-product material of the cement manufacturing process. Over the past several years dramatic advances have been achieved in the management and use of cement kiln dust, thus reducing its dependency on landfill disposal. Sustainability is the cornerstone of the cement industry, not only in the products that use cement, but also in its manufacturing process. From 1990 to 2006, the U.S. cement industry has reduced the amount of landfilled CKD 47 percent. This reduction in landfilled CKD comes despite the fact that domestic clinker production, as reported by the participants in the PCA CKD study, increased 95 percent during this same period. Overall clinker capacity in the U.S. has increased 28 percent since 1990. Many of the older, inefficient plants are being replaced by more modern plants or being renovated with new technologies to be more efficient as well as more environmentally friendly. The majority of CKD is recycled back into the cement kiln as raw feed. In addition, new technology has |
