WASTE CEMENT AND CONCRETE MANAGEMENT AS COST-

Cement production generates GHG from two main sources: calcination and fuel combustion. Calcination is the chemical process in which calcium carbonate (CaCO3) is heated to high temperatures, converting it to lime or calcium oxide (CaO), and releasing carbon dioxide (CO2). So it is not surprising that the main type of GHG from cement production ...

Cement Production - an overview ScienceDirect Topics

Cement production is one of the largest industries in the world. Annual world production in 2013 was approximately 4 GT (of which, about half was in China). It is produced in kilns at around 1400o C (2500 o F), and approximately 750 kg (1650 lb) of CO 2 are released for each tonne (2205 lb.) that is made.

CO2 Emissions Profile of the U.S. Cement Industry

Cement production also is a key source of CO2 emissions, due in part to the significant reliance on coal and petroleum coke to fuel the kilns for clinker production. Globally, CO2 emissions from cement production were estimated at 829 MMTCO2 in 2000 7, approximately 3.4% of global CO 2 emissions from fossil fuel combustion and cement production.
