About one-third of the raw material used to make paper in the U. S. is reidue wood chips and scraps left behind from the forest and sawmill operation. These ‘’ leftovers’’ would probably be burned or discard 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 then 8 inches in diameter or larger trees not suitable for solid wood products, typically are harvested for papermaking. Papermakers combine mechanical, chemical and recycled pulp in varying amounts to produce the highest quality paper required by from the least possible amount of fiber. Some people say that it takes ‘’17 trees to make a ton of paper’’. Each year, the U. S. forest community plants some 1. 5 billion seedlings. That’s an average of more than 4 million new trees planted everyday! There are more than there were 70 years ago. 37 percent of the fiber used to make new paper products in the U. S. came from recycled sources in 2007. Newspaper 89 percent corrugated boxes 81 percent office paper 74 percent magazines 54 percents telephones directories 37 percent papermaking came from recycled paper 33 percent whole trees and other plants 33 percent wood chips and scraps from sawmills 33 percent. Everytime paper is recycled the fibers get shorter. After being recycled five to seven times, the fibers become to bond into new paper. Recycled paper masking tape, paper money, globes, bandages, dust masks, hospital gowns, coffee filters, lamp shades, car insulation, animal beddings, planting pots for seedlings, and egg cartons.
