  • Global 2 emissions from cement production

    Anthropogenic emissions of carbon dioxide to the atmo-sphere come from three main sources: (i) oxidation of fos- sil fuels, (ii) deforestation and other land-use changes, and (iii) carbonate decomposition. Cement – the largest source of emissions from the decomposition of carbonates – is a bind-ing material that has been used since ancient times. But it was following World War II that the ...

  • CARBON DIOXIDE EMISSIONS FROM THE GLOBAL

    The cement industry contributes about 5% to global anthropogenic CO emissions, making the cement industry an important sector for CO-emission mitigation strategies. CO 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 CO emissions from cement making, including process and energy ...

    Cement industry has been always among the largest CO 2 emission sources. Almost 5–7% of global CO 2 emissions are caused by cement plants, while 900 kg CO 2 is emitted to the atmosphere for producing one ton of cement. In this work, global strategies and potentials toward mitigation of CO 2 emissions in cement plant have been discussed and the most promising approaches have been
