MONTREAL, Nov. 17 /PRNewswire/ - Domtar Corporation (NYSE/TSX: UFS) today announced the on-schedule start up of its new fluff pulp machine in Plymouth, North Carolina. The mill will have an annual production capacity of approximately 444,000 metric tons.

"This is another successful step in our strategic roadmap of pursuing growth opportunities that capitalize on our existing strengths and core competencies," said John D. Williams, President and Chief Executive Officer of Domtar. "The reconfiguration of the Plymouth mill to 100% fluff pulp production provides Domtar with a stronger presence in a growing global market and positions us as a leading fluff pulp manufacturer."

Mr. Williams also added, "The Plymouth mill is a competitive, world-class asset and I am confident that this will bring a renewed sense of purpose to its workforce and stability to the community. I would like to congratulate my colleagues at the mill for delivering this project on schedule and with an excellent safety record."

The Domtar-Plymouth mill's conversion to 100% fluff pulp production was previously announced in October 2009. Once running at full capacity, the mill will exclusively produce fluff pulp and operate two fiber lines and one fluff pulp machine.
