Making Paper from Wood
Do you know
that paper is made from wood? Ya, paper that we use in our daily life is
made from wood or tree. The process of making paper from wood is quite
long. The process is called wood-chipping. Wood-chipping is a process
used to obtain pulp and paper products from forest trees.
The
wood-chipping process begins when the trees are cut down in a selected
area of the forest called a coupe. 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 wood chips. The wood chips 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.
Finally the pulp is rolled out to make paper.
