Domtar’s Windsor Mill woodroom upgrade cuts fiber loss and increases productivity

Domtar is the largest integrated manufacturer and marketer of uncoated freesheet paper in North America, and one of the largest manufacturers of pulp in the world. The company count on a network of 13 pulp and paper mills and 11 manufacturing and converting facilities which gives them approximately 2.7 million tons of papermaking capacity and 1.5 million air-dried metric tons (ADMT) of market pulp capacity annually.

Domtar contracted Progesys for construction management and commissioning in an integrated team model. The Windsor Mill woodroom modernization project consists in demolition of one of the two-chip production lines and the installation of the new rotary debarker and horizontal chipper processing system. During the dismantling, demolition, and construction phases, the second line, present in the same building, continued to operate to maintain a maximum production capacity. The combined demolition and construction phases required 10 months including the installation of structure around debarker infeed, installation of deck and loader system, building mechanical modifications as well as electrical and instrument works.
