= ﻿HOW PAPER IS MADE =

Paper is made from a mix of trees, some are hard wood, some are soft wood, some are tall, some are old, some are wide and some are thin.
===The chopped trees are cut into logs and transported often by water to the pulp-mills. There they are first debarked in a large machine. Then broken down into a pulp by grinding or by boiling with chemicals in a pressure cooker called a digester.===

===The bark is striped off by a machine and may be used as fuel. The pulp is pressed into thin sheets. The sheets of wet pulp go through rollers which presses them a bit more. The sheets are dried on huge heated rollers which then becomes paper, the paper is rolled up or cut into sheets.===
