Cement Industry Overview

The cement industry has boosted efficiency by concentrating new capital investment in plants that use the dry process of cement manufacture, and by phasing out operations that rely on the more energy-intensive wet process. Since 1974, the number of wet process kilns has dropped from 234 to 25 -- a decline of 89 percent -- while the number of dry process kilns has only been reduced from 198 to
