Windsor, Quebec, Canada, 11 January 2011 --
Domtar will upgrade its biomass boiler and reduce steam demand for two paper machines with CAD 24.8 million in federal funding being provided for its Windsor pulp mill under the Pulp and Paper Green Transformation Program.
The boiler upgrade includes improving the lower furnace combustion to enable the boiler to operate at increased steam flow by replacing the lower furnace arches, upgrading the wood residue grinder, and adding two new hog grinders.
Lowering the steam demand for two paper machines will be accomplished by installing new steam boxes to better control moisture content of the papers, produce a more uniform product, and save on steam to dry sheets; installing a stock screening system; and dedicating an existing pulp storage tank for recycled pulp storage.
These upgrades will result in a higher volume of alternative fuels being used at the mill to generate renewable energy and a reduction of 8400 metric tons per year in greenhouse gas emissions. In addition, the projects will lead to the elimination of approximately 25,000 metric tons of solid waste a year through the use of wood waste and other alternative fuels. As well, the mill will use less steam to produce more paper with recycled content
The Windsor mill has been in operation since 1865 and was acquired by Domtar in 1961. The mill produces uncoated freesheet paper, digital paper, copy paper, laser forms bond, envelopes, and recycled paper. It also produces bleached hardwood wet-lap market pulp.
The investment in Domtar's Windsor mill is just one of several announcements related to the Pulp and Paper Green Transformation Program made across the country on 06 January 2011. The investments totaled CAD 278 million.
The Pulp and Paper Green Transformation Program provides companies with credits based on their production of black liquor (CAD 0.16/L) in 2009. Black liquor is a liquid by-product of the pulping process used to generate heat and power.
Firms then have until 31 March 2012, to draw on these credits to finance approved capital projects that offer demonstrable environmental benefits, such as improvements to their energy efficiency or their capacity to produce alternative energy.
