Why not research and invent new products than can replace the carbon intensive process of making cement? Well, that is exactly what is happening amongst some forward-thinking people! As I mentioned before, a tremendous amount of CO2 is emitted during the process of producing cement. The manufacturing of one ton of portland cement produces one ton of CO2 emissions. This is not an option moving forward! Portland cement accounts for 8% of global CO2 emissions.

Let’s talk about the ingredients of cement that makes it’s CO2 emissions so high. Portland cement is a mixture of sand, gravel, water, and lime. High CO2 emissions are produced during the making of lime which acts as the glue to the cement. First you must extract the raw material… Continue reading →
