Brompton Biomass Cogeneration Plant

Kruger Energy has built and commissioned a 23-MW biomass cogeneration plant at the Kruger paper mill in Brompton (Sherbrooke), Québec.

The plant, which went on line in 2007, includes a hog boiler which burns papermill sludge, bark and other wood residue, as well as a steam turbine wich generates electrical energy that is sold to Hydro-Québec Distribution under a 20-year power purchase agreement and provides the steam required to dry the paper.

Highlights

• Production of green energy
• Greenhouse gas emissions reduced by 83,000 metric tons annually, which compares to removing 18,000 vehicles from the road
• Paper mill sludge, bark and particle waste diverted from landfills (600 dry metric tons per day)
• Less bark waste reduces the risk of leachate contamination
• Reduced fossil fuel consumption (30 million liters annually)
• Air quality improvement
• No new electrical line installed 

Impact reduction measures:

• Silencers installed to prevent increased noise levels
• Limited handling of sludge to eliminate potential odors
• Training program for heavy-truck drivers to ensure speed limits and noise reduction measures are observed
• Efficient cooling tower used to minimize the vapor plume
• New facility integrated with the current mill
