As with the other emissions classes in this review, limits for mercury emissions from cement plants are on a downward trend. From 1 January 2016 Germany will reduce its legal limit for mercury emissions from cement plants down to .02mg/Nm 3. This will make it the most stringent regulator of mercury emissions in the global cement industry.
