  • Cement Production - an overview ScienceDirect Topics

    The production of cement is either through the wet or dry process with the dry process as the preferred option because of the lower energy intensity. Cement production accounts for about 5% of total anthropogenic emissions IFC, 2017). Cement-based structures constitute the largest surface area of all man-made structures (Odigure, 2009). World cement demand was about 2.283 billion tons in 2005 ...

  • 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 ...
