Global cement emissions standards

The new emissions standard for Chinese cement SO 2 emissions limits for the period after 1 March 2014 is not yet known. The USA is the only country to regulate its emissions limits in non-SI units, with its Portland Cement Maximum Achievable Control Technology (PC MACT) regulations stating a limit of 0.4lb/ton of clinker produced.

Air Pollutant Emissions Projections for the Cement and

In this study, we analyzed and projected the total PM and SO2 emissions from the Chinese cement and steel industry from 2010–2050 under three different scenarios: a Base Case scenario, an Advanced scenario, and an Advanced EOP (end-of-pipe) scenario. We used bottom-up emissions control technologies data and assumptions to project the emissions.

Print Fingertip: Portland cement and the environment

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.
