How is paper produced?
Paper starts with fibers. Wood is the most common source, but cotton, linen and others can be used and often are. The fibers are mixed together into slurry. Chemicals are used to clean and whiten or color the slurry. The slurry is laid out on a screen and the water drains away leaving a layer of fibers, patterns in this screen leave watermarks that can be seen when you hold the paper up to the light. These are rolled smooth and dried and then cut into the appropriate size. The production of pulp paper can be an ecology and environmentaly friendly process, that insures both renewable habitat. The biggest potential loss is the water used in processing. == == == == A little more than one third of a tree is needed to make 3,000 sheets of copy paper. The actual answer of course depends on the tree and on the type of paper. For more details see the related link to Conservatree. Nearly 4 billion trees worldwide are cut down each year for paper, representing about 35% of all harvested trees. Paper is one of the easiest products to recycle. Although paper manufacturers typically manage and replant forests that they harvest, you can reduce the need to cut as many trees by recycling paper and cardboard.
