Making Paper from Woodchips

Do you have any paper in your bag? It may seem like a silly question but do you know how to make paper? What is paper made of? Right. And how about wood chipping? Have you ever heard about it? Well, wood chipping is a process used to obtain pulp and paper products from fores trees.

First of all, the tops and branches of the tress 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. Hmm,... at this stage they are either exported in this form or changed into the pulp by chemicals and heat. I almost forgot, the pulp is then bleachead and the water content is removed. Finally, the pulp is rolled out to make paper.
