Production of cement refers to the method of energy and resource used, which absorbs almost 12% to 15% of total industrial energy utilization [28]. It also actually reported for 5% to 8% of CO 2 emissions from cement production [26]. Global cement manufacturing hit 4.1 Gt amount of CO 2 during 2017 [30].

CCUS applications do not all have the same cost. Looking specifically at carbon capture, the cost can vary greatly by CO 2 source, from a range of USD 15-25/t CO 2 for industrial processes producing "pure" or highly concentrated CO 2 streams (such as ethanol production or natural gas processing) to USD 40-120/t CO 2 for processes with "dilute" gas streams, such as cement production and ...

Non-renewable energy comes from sources that will run out or will not be replenished in our lifetimes—or even in many, many lifetimes. Most non-renewable energy sources are fossil fuels: coal, petroleum, and natural gas.Carbon is the main element in fossil fuels.For this reason, the time period that fossil fuels formed (about 360-300 million years ago) is called the Carboniferous Period.
