"Our customers want environmentally sustainable packaging. They appreciate that our corrugated packaging is recyclable and averages 50% post-consumer recycled fiber content and 57% total recycled fiber content.. Now, this third- party, SFI certification offers further assurance that our forest resource is managed using sustainable forestry standards and that our operations and products are consistent with SFI sustainable forest management principles," says James R. Keller, senior vice president, Containerboard Packaging & Recycling.

To earn the use of the SFI-certified procurement label, two-thirds of a company's packaging raw material must originate from mills with certified wood fiber procurement systems or recycled paper sources. Weyerhaeuser exceeds this standard with eighty-five percent of our packaging plants' raw material coming from Weyerhaeuser mills with procurement systems certified to the SFI standard.

The SFI program is a comprehensive system of principles, objectives and performance measures developed by professional foresters, conservationists, scientists and other stakeholders from outside industry. The program combines the perpetual growing and harvesting of trees with the long-term protection of forest biodiversity, wildlife, plants, soil and water quality and other forest values.
