How Paper Is Made By: Nathan Oleson

Proces of tre makeing Trees are all around you. But have you ever really thought about how they're put together? They're pretty cool. Just look at a tree trunk. The bark protects the inner wood from weather, insects and other dangers. Just inside the bark is a thin layer called the cambium, whose cells become both bark and inner wood. Next issapwood, which carries nourishing sap throughout the tree the same way our blood flows through our bodies to nourish us. Heartwood is the innermost part of the trunk, and even though it isn't alive, it provides the tree with strength and structure. All that wood material is formed of fibers, tiny cellulose strands stuck together with a natural adhesive material called lignin. It's by separating and reorganizing those fibers that we make paper. Consider the source Some paper is made brand-new from trees - either small trees harvested just for that purpose, or from sawmill scraps left over when larger trees are made into lumber. A second source of papermaking material is recycled fiber. Each year, more and more paper is recycled - its fibers used a second, third or fourth time. Every year, about 50% of the paper Americans use is recovered for recycling and other uses. Almost all of the paper you use today is made of wood fibers. Some specialty papers, like stationery and money, are made from linen, cotton, or other plants. Other papers contain a combination of cellulose fibers and synthetics such as latex. Still others are made completely from synthetic materials such as polyolefine. You might find latex in a waterproof mariner's chart, or polyolefine in a rugged courier envelope. But you'll find natural fiber paper almost everywhere!

Simply Put After harvesting, trees are cut into logs and are transported to the mill. At the mill, a debarker removes the bark from each log. The log is cut into boards of varying sizes. The wood that's left over is then converted into wood chips. The wood chips are then put into "pulp digesters" where they are broken down by steam and chemicals into a gloppy pudding of cellulose fibers and other wood components. A pump sprays a thin layer of the liquid paper pulp onto a moving wire screen.  As the pulp is carried along by the screen, the water in it drops away, and the cellulose fibers become matted together, forming paper. While the paper is still damp, it is fed through a series of heated rollers which press it and dry it. The paper is then spooled into huge rolls, cut into various sizes, and converted into paper products.

The end Yep that’s how paper is made.
