tree life cycle

step 1: trees are typically grown to make paper out of them. but eventually they are cut down and put through a debarker and chipper
.
step 2: this is called the pulp preperation which is washed refined and sometimes bleached then turned into a pulp slush which than color dyes and coatings are mixed in.

step 3: the pulp travels down a screen and the water is drained away and recycled as the paper turns into a sheet or web than it is squeezed in between big rollers to remove most of the water and than heated so it dries out the rest of the water

step 4: the finished paper is wound into rolls an then cut into little sheets to for more manageable moving
