The US cement industry has seen a significant number of plants affected by emissions limits placed on kilns under NESHAP and CISWI regulations. Now, it appears that Canadian cement kilns will soon face similar struggles to reduce emission levels. Under a new Multi-Sector Air Pollutants Regulation, cement kilns in Canada would be required to make significant reductions in SOx and NOx emissions. The proposed regulation would provide the first mandatory national emission standard for some industries. Preliminary numbers provided by the Canadian government place total emissions reductions at 96,000 tons of SO2 and 63,000 tons of NOx between 2017 and 2035.
