Air

Resolute Forest Products Thunder Bay produces kraft pulp. And like every pulp mill in the world, emits a “rotten egg” smell from the process. This doesn’t mean Resolute is not concerned about air emission. In fact we have aggressive air quality programs currently in place with enhancements planned for the future, as part of Resolute’s overall Air Improvement Program.

All machinery impacts the quality of our air by releasing:

  • dust particles
  • exhaust
  • heat
  • and odour

Environment Air - Environment Air At Resolute we’re proud to say we’ve been highly successful at reducing our air emissions. In fact, in our mills our performance is nothing short of dramatic—with reductions of over 80% in just 10 years.

So why does our kraft mill still smell?

But attention to air quality at Resolute involves a lot more than just getting rid of the smell. For example, massive “precipitators” trap ash and other solid material before it can hit the environment. Other equipment reduces gases and heat, converting some these into energy to run the mill.

All of our operations in northern Ontario have air quality programs in place. To find out more go to >> air: pulp and paper air: woodlands, air: sawmill.

OVERVIEW

Facts About TRS Total Reduced Sulphur Compounds (TRS) are gases that result from various steps in the manufacturing of kraft pulp.

Particulate Matter Fact Sheet Particulate matter emissions consist of small sized air-borne particles.

C' Recovery Boiler Overview Chemical Recovery boilers are critical to the operation of kraft pulp mills.

#6 Power Boiler The #6 Power Boiler is located at the north end of the Kraft Mill.

# 3 Power Boiler The #3 Power Boiler is located in the Steam Plant on the banks of the Kaministiquia River.

INITIATIVES

Overview of Recaust Process Calcium oxide (CaO or lime) is used in the kraft recovery process. First, some background about the process is in order.

Research in Air Quality Partners involved in air quality research include the Pulp and Paper Research Institute of Canada (PAPRICAN), Lakehead University, Lakes Environmental (Waterloo, Ontario), the University of Waterloo, and the Pulp and Paper Centre at the University of Toro

Dilute Non-Condensible Gas Collection Project The kraft pulping process involves cooking wood chips in a chemical pulping solution under high pressure and temperature.

PLANNING & PROGRAMS

Ambient Air Monitoring Data Resolute has an ambient air monitoring network that continuously measures various air quality parameters within the community.

Measuring Air Emissions The Province of Ontario monitors compliance with environmental regulations, including that of air quality.

Air Improvement Program Almost 10 years ago, based on a review of emission tests on our stacks, the Resolute Forest Products Thunder Bay mill began down the path to improving air quality.

Advanced Air Emission Modeling Project The Thunder Bay Operation was constructed in the early 1920s and like the mill, the adjacent City has continued to grow and prosper.
