Cement Energy Environment

11 In this article, I will only address the part related to the digital maturity in this holistic value chain model. CO 2 Footprint in Cement Industry When evaluating the carbon footprint of concrete, it is important to recognize the difference between cement and concrete. While cement is an energy-intensive intermediate product, the final output concrete is actually one of the world’s most CO 2 efficient and sustainable construction materials”. CO 2 emissions from a cement plant are divided into two source categories •Combustion (40 percent of emissions) •Calcination (60 percent of emissions) The combustion-generated CO 2 emissions are related to fuel use. The CO 2 emissions due to calcination are formed when the raw materials (mostly limestone and clay) are heated to more than 1450°C and CO 2 is liberated from the decomposed minerals. During the life of a concrete, the concrete that is exposed to air slowly absorbs nearly 60 percent of the CO 2 released by calcination during the cement manufacturing process. The focus of reductions in CO 2 emissions during cement manufacturing is on energy use, and the cement industry is Yet, we must consider the other CO 2 emissions in cement value chain in the following steps 1. Quarry earthmoving equipment 2. Purchased raw material transportation 3. Purchased fuel transportation
