Air

Tomorrow's Mill will be the cleanest in Canada resulting in no detectable odour, clean air, and no visible plumes above the mill. 

Among the many new technologies leading to improved air quality is the replacement of the power boiler scrubber with a wet electrostatic precipitator which will result in a high-efficiency collection of the fine particulate matter and contribute to eliminating visible plumes above the mill. 

Other predicted air improvements include:

• 80% reduction in total reduced sulphur (TRS) emissions
  • No detectable odour in surrounding communities
• 75% reduction in Power Boiler particulate
• 70% reduction in visible stack plumes
• 50% reduction in chlorine dioxide emissions
• 9% reduction in greenhouse gases

No detectable mill odour in surrounding communities

Outcome: No detectable mill odour during normal operating conditions

• Convert the recovery boiler to a low-odor configuration.
• Collect vent gases from the brown stock washer hoods to destruct in the power boiler.
• Install a dedicated combustion device for both the concentrated and diluted sulphur-containing off-gases.
• Implement a company “Zero off-gas venting” policy.

Reduce visible plumes

Outcome: 70% reduction of visible mill plumes

• Replace the power boiler scrubber with a wet electrostatic precipitator, providing a high-efficiency collection of fine particulate matter
