Making Paper from Woodchips
General statement:
Woodchipping is a process used to obtain pulp and paper
products from forest trees. The woodchipping process begins when the trees are
cut down in a selected area of the forest called a coupe.
Squence of explanation:
Next the tops and branches of the trees are cut out and then
the logs are taken to the mill. At the mill the bark of the logs is removed and
the logs are taken to a chipper which cuts them into small pieces called
woodchips. The woodchips are then screened to remove dirt and other impurities.
At this stage they are either exported in this form or changed into pulp by
chemicals and heat. The pulp is then bleached and the water content is removed.
Closing:
Finally the pulp is rolled out to make paper.
