Wood fiber--where does it come from?

You may be surprised to learn that about one-third of the raw material used to make paper in the U.S. is residue - wood chips and scraps left behind from forest and sawmill operations. These "leftovers" would probably be burned or discarded if not used by the paper industry.

Another third of the raw material is recovered paper. Although some papers contain 100 percent recycled fiber, papermakers often combine various amounts of recycled and new fiber to produce the desired quality and grade of paper.

Only about one-third of the fiber used to make paper in the U.S. is from whole trees, which the industry calls round wood. It is not considered economical to use large logs for paper when they could instead be used for lumber. For this reason, only trees smaller than 8 inches in diameter, or larger trees not suitable for solid wood products, typically are harvested for papermaking.

Pre-consumer and post-consumer paper--what's the difference?

Pre-consumer recovered paper consists of trimmings and scraps from printing, carton manufacturing, or other converting processes which are reused to make pulp without reaching the final consumer.

Post-consumer recovered paper (like old corrugated boxes, newspapers, magazines, and office paper), has been used by the ultimate consumer and is then returned to the mill for recycling.
