    Retrofitability Of Co 2 Capture Technologies To Cement

    2 emissions from the cement industry make up 6 to 7 of the total anthropogenic co 2 emissions. co 2 generation is an inherent part of the cement production process, due to the calcination of limestone (caco 3 cao co 2). around 60 of the direct co 2 emissions are released from this conversion, while 40 comes from burning of fuels.
