Last week, Fortress Specialty Cellulose Inc. (FSC) signed an agreement with Forevergreen Energy Inc. to supply recovered energy to the mill in Thurso, Quebec.
Recovered energy is energy that is harnessed from hot streams with potential high energy content, such as hot flue gases, steam from cooling towers, or even waste water from different cooling processes. In the case of the Thurso mill, energy gathered from recovery boilers used during the pulping process will be channeled through a waste recovery system on site and recycled in the form of energy for the mill.
Forevergreen – a subsidiary of the Ottawa clean-tech firm Thermal Energy International Inc – currently has a heat recovery unit in the mill, which was put it at the request of the mill’s previous owners, Fraser Papers.
FSC’s new contract with Forevergreen provides many benefits, both for the company and for the environment. Using recycled energy decreases overall fuel and energy costs and also has the capacity to reduce pollution.
This isn’t the only mill in which Fortress uses recycled energy. At the Landqart mill in Switzerland – where Fortress Paper Ltd. makes security and specialty papers – the company imports steam from a refuse incinerating plant 7km away as a source of heat in the process of converting pulp to paper.
FSC is also developing a cogeneration plant on site in Thurso that will generate energy by using excess heat from the cellulose manufacturing process and from mill waste. The energy created in this process will be supplied not only to the mill, but is also being purchased by the province of Quebec for the region’s power grid.
The recovered energy agreement with Forevergreen is effective starting this month until December 31, 2012. At the end of this contract, FSC has the option to extend the contract for up to two years or to purchase Thermal’s system for nearly $1 million.
