PDF CO2 Emissions Profile of the U.S. Cement Industry

2 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

In fact, for every ton of clinker (a product of the cement kiln process of making Portland cement) replaced, CO2 emissions are reduced by approximately 0.8 ton. Since fly ash is used as a substitute for clinker, they reduce the amount of material used to produce cement and also the fuel required to produce the clinker.

Portland cement and the environment - Concrete

Portland cement and the environment. Portland cement is manufactured by heating limestone or chalk with clay in a rotary kiln to a high temperature (about 1450°C) to produce hard nodules of clinker that are then ground with a little gypsum in a ball mill. The firing process consumes significant quantities of fuel, usually coal or petroleum coke.

Carbon Dioxide Emissions From the Global Cement Industry

Abstract The cement industry contributes about 5% to global anthropogenic CO2 emissions, making the cement industry an important sector for CO2-emission mitigation strategies. CO2 is emitted from the calcination process of limestone, from combustion of fuels in the kiln, as well as from power generation. In this paper, we review the total CO2 emissions from cement making, including process and

Emissions from the Cement Industry

Cement manufacturing is highly energy- and emissions-intensive because of the extreme heat required to produce it. Producing a ton of cement requires 4.7 million BTU of energy, equivalent to about 400 pounds of coal, and generates nearly a ton of CO 2. Given its high emissions and critical importance to society, cement is an obvious place to

And depending on how that cement is produced, this can increase the material's environmental impact. This is in part because when calcium carbonate is fired in a kiln to produce conventional cement, a chemical reaction occurs that produces carbon dioxide (CO 2). Another source of cement's CO 2 emissions come from heating cement kilns. This
