CHICAGO—  Wood fiber from sustainably managed forests is essential to the paper cycle. Approximately 6% of the recovered paper supply is used in printing and writing grades. In the U.S. and Canada, the majority of the required fresh wood fiber used in papermaking comes from sawmill chips, which are a by-product of lumber production. North America benefits from a good supply of recycled fiber which is used locally to manufacture paper products. In Canada, almost 70% of the paper is recovered for recycling.  82% of recovered paper is used in tissue, container boards, and other packaging or board products.
