To make paper from trees only takes a few steps. Once trees are harvested in the forest they are taken to a paper mill where their bark is removed. The wooden logs are then chipped into tiny flakes. These chips are mixed with chemicals and water to break them down into individual fibers. The chemicals are necessary to break down substances called lignins in the wood.
Lignins are natural glues which hold plant fibers together.
At this point, the mixture of fibers, chemicals, and water is called pulp. The slushy pulp is spread out over large mesh screens and allowed to dry. As the pulp dries, it is pressed flat and put on a role. Now it is considered paper. Of course there are several types of paper.
