An inventory of primary air pollutants and CO2 emissions from cement
It is estimated that the clinker to cement ratio could drop to 65% (CCA, personal communication). A few cement plants in China have begun to use solid waste as a fuel in kilns as a substitute for coal. WBCSD (2009a) projected that the share of alternative fuel in clinker fuel use in Asia could increase at an annual rate of 0.6%. CCS ...

New approach suggests path to emissions-free cement
Ordinary Portland cement, the most widely used standard variety, is made by grinding up limestone and then cooking it with sand and clay at high heat, which is produced by burning coal. The process produces carbon dioxide in two different ways: from the burning of the coal, and from gases released from the limestone during the heating.
