VANCOUVER ISLAND—  Paper Excellence says it is indefinitely ceasing its paper operations at one of its Vancouver Island facilities in two months. In an announcement Thursday, the company said its Catalyst Crofton facility, south of Nanaimo, B.C., will stop producing paper in early December, a move that's expected to affect at least 150 workers. This is the second Paper Excellence mill to indefinitely cease operations in B.C. within the last year. In December, the company shut down its Catalyst Paper tiskwat mill in Powell River, B.C. "Paper Excellence is working with both Provincial and Federal Governments while it conducts studies at the Crofton facility to consider accelerating its conversion into natural food and packaging grades," said the company Thursday.
