Cement production accounts for up to 8% of total anthropogenic CO2 emissions each year (Miller, John, Pacca, & Horvath, 2018). This large amount of CO2 emissions can be attributed to the manufacturing process of cement. Cement is manufactured through a closely controlled chemical combination of calcium, silicon, aluminum, iron and other ingredients. Calcium carbonate, added as limestone and heated to high temperatures converts to calcium oxide and releases CO2 into the environment. This results in one pound of CO2 emitted for every one pound of cement produced (Goguen, 2013). In addition, heating these materials to temperatures over 1800 degrees Fahrenheit, which is necessary for cement production, requires the combustion of large quantities of fossil fuels, further contributing to CO2 emissions.
