A new electrostatic precipitator at Kruger’s Wayagamack mill in Trois-Rivières, Que., has already cut the biomass boiler’s particulate matter emissions by 85 per cent. The new equipment was installed in June at a cost of $4.5 million.
Kruger recently shared the air emissions measurement results for its Wayagamack mill, covering the period since commissioning of the new electrostatic precipitator.
This improvement is consistent with the results achieved with a previous electrostatic precipitator installed on the mill’s recovery boiler’s flue gas scrubbing system. That project had been completed in 2012 at a cost of $3.5 million.
Overall, the combined effect of both precipitators has resulted in a 75 per cent drop in the Wayagamack mill’s particulate emissions.
Since 2012, Kruger has invested approximately $10 million in its two paper mills in Trois-Rivières to make technological improvements that help the environment.
“Kruger continually invests in its facilities to lessen the impact of its operations on the environment, while ensuring the sustainability of its plants and therefore preserving quality jobs in the region,” says François D’Amours, senior vice-president and COO, Kruger Publication Papers Inc.
Both mills have significantly reduced their fossil fuel consumption by prioritizing the use of energy from renewable resources, which has led to a marked decrease in their GHG emissions, so much so that the mill on Gene H. Kruger Boulevard is no longer considered a major greenhouse gas (GHG) emitter.
According to Kruger, from 2008 to 2013, the combined GHG emissions from the Trois-Rivières and Wayagamack mills fell from 182,271 T to 58,478 T, which is the equivalent of taking some 26,000 cars off the road annually.
