We invested $180 million on air quality improvements at our three Prince George pulp mills in the last five years, delivering a 40% reduction in particulate discharge. This is fully in line with the Prince George Air Improvement Roundtable’s goal for reduced emissions from all major sources in the airshed by 2016.
In 2015, we commissioned the electrostatic precipitator on a power boiler at Prince George Pulp and Paper, which significantly lowered particulate emissions, and replaced the atmospheric black liquor fibre filter at Intercontinental, which eliminated the highest source of TRS from the mill. Prince George Pulp and Paper also improved its energy efficiency by burning boiler ash with the highest heat value a second time. The ash reinjection system, which became fully operational in June, exceeded expectations with 3% hog fuel savings and reduced the volume of ash to landfill by 60% to 70%.
