Cement production accounts for 8% of CO2 emissions worldwide. Hopefully we'll start seeing this process and others like it go mainstream in the near future and make a dent in that figure.
A diagram of the process, which encompasses production of both portland and masonry cement, is shown in Figure 11.6-1. As shown in the figure, the process can be divided into the following primary components: raw materials acquisition and handling, kiln feed preparation, pyroprocessing, and finished cement grinding.
