How Is Paper Recycled?
Recycled paper is new paper made out of old. Old newspaper is first shredded into little pieces. Then it is put into chemicals that clean it and turn it into a soggy mush, called pulp. Pumps spray the pulp onto a moving screen in the paper-making machine.
The water in the pulp drains through the screen, leaving an even mat of paper fibers. Rollers press the mat into a flat sheet of paper. When it is dry, it is fresh, clean paper–thus, recycled paper.
Since most paper is made from trees, recycling old paper is one way many of our trees can be saved. Recycling one ton of paper saves roughly 17 trees. It has been estimated that recycling half the world’s paper would avoid the harvesting of 20 million acres (81,000 km²) of forestland.
