Government of Canada Supporting Environmental Improvements at The Pas Mill

The Government of Canada’s Pulp and Paper Green Transformation Program (PPGTP) is laying the groundwork for a greener, more sustainable future for Canada’s pulp and paper sector by supporting smart investments that improve a mill’s environmental performance. This support includes investments in technologies that enhance energy efficiency and the production of renewable energy.

Tolko Industries Ltd. will be applying its PPGTP credits toward a capital improvement project that will improve the energy efficiency and reduce fossil fuel consumption of its mill in The Pas, Manitoba.

The Pas mill operates one power boiler on site that produces steam from both bark and wood waste (60 percent) and bunker C and waste oil (40 percent).

During the process of evaporating water and concentrating black liquor into a combustible fuel, solids tend to bake onto the surface of the evaporator tubes, thereby fouling the tubes and reducing their efficiency. As the tubes become fouled, higher temperatures are required to evaporate the water, which leads to a negative feedback loop of increased baking-on of solids, lower efficiencies and increased power consumption for steam generation.

The new mini-boil system will allow the #1 and #2 effects of the multiple effects evaporator (MEE) to be automatically flushed with water once every four days without interrupting the circulation of black liquor in the rest of the MEE.

Prevention of the gradual fouling of the evaporator through the mini-boil system will reduce the mill’s consumption of steam, fossil fuels and electricity — leading to lower greenhouse gas emissions.

Tolko Industries Ltd. is a private, Canadian-owned forest products company based in Vernon, British Columbia. Founded in 1956, Tolko manufactures and markets specialty forest products, including lumber, plywood, veneer and kraft papers. The company has manufacturing operations across Western Canada and forest management operations in British Columbia, Alberta, Saskatchewan and Manitoba.

Tolko operates a specialty kraft paper mill in The Pas, Manitoba, which it purchased in 1997. The mill is an integrated facility that produces pulp from chips purchased from the company’s woodland operations and external sources. The mill consumes all of the pulp it produces and manufactures several grades of unbleached paper.

How the Pulp and Paper Green Transformation Program Works

Thirty-eight pulp and paper mills across Canada, representing 24 companies, generated credits under the Pulp and Paper Green Transformation Program based on their 2009 production levels of black liquor, a liquid by-product of the pulping process used to generate heat and power. Qualified companies are required to submit project proposals for their facilities and have until March 31, 2012, to apply the credits to environmental improvement projects. The program is working with these companies as they prepare their project proposals and as projects undergo environmental assessments.

Under the terms of the program, eligible firms can invest the credits generated at one mill in any of their pulp and paper facilities across Canada. Consequently, newsprint and pulp mills that did not generate credits could still benefit from this program.  

This program does not limit funding recipients from seeking grants from provincial, municipal or other funding sources to help ensure they meet their environmental stewardship goals.

By investing in clean energy technologies, this program is helping the forest industry contribute to the growth of a domestic clean energy industry and creating and maintaining high-quality jobs for Canadians, while helping to protect and preserve our environment.
