Emissions from the Cement Industry State of the Planet
网页2012年5月9日Cement manufacturing is highly energy- and emissions-intensive because of the extreme heat required to produce it. Producing a ton of cement requires 4.7 million BTU of energy, equivalent to about 400 pounds of coal, and generates nearly a ton of CO 2. Given its high emissions and critical importance to society, cement is an obvious place to
