Biomass cogeneration uses industrial waste such as wood residue to produce electricity for the grid, as well as steam for industrial use. When compared to the separate generation of electricity and steam using fossil fuels, biomass cogeneration offers several environmental benefits, including a significant reduction of greenhouse gas emissions.
The most important type of biomass in Canada is industrial wood waste, which is used to produce electricity and steam. The pulp and paper industry is by far the largest industrial user of bioenergy, which accounts for more than half of the energy used in this industry. (source: Natural Resources Canada website)
Did you know?
- At the end of 2014, Canada had 70 bioenergy power plants with a total installed capacity of 2,043 megawatts.
- The majority of this capacity was built around the use of wood biomass and spent pulping liquor, as well as landfill gas.
- In Canada, 8.7 gigawatt-hours were generated using wood refuse, spent pulping liquor, landfill gas and organic municipal solid waste in 2014.
- Most of the biomass-fired capacity comes from provinces with significant forestry activities: British Columbia, Ontario, Quebec, Alberta and New Brunswick.

Canada Biomass Projects
Kruger Energy manages two biomass cogeneration plants. The first, in Brompton, Quebec, has a capacity of 23 MW. The second in Corner Brook, Newfoundland has a capacity of 17.6 MW. Both plants produce high-pressure, high-temperature steam from a biomass boiler which feeds a steam turbine.
The cogeneration plant in Brompton mainly uses residue from construction wood, while the one in Corner Brook mainly uses tree bark.
