Recycling paper is a big part of keeping our environment clean.
When paper, cardboard or wood products are recycling ensures the water is polluted 35 percent less and the air is polluted 74 percent less than they would be otherwise.
the recycling process can be highly complex.
first, the customer throws out old magazines, juice cartons, and even telephone directories.
second, a recycling truck comes around to homes and office buildings.
this truck picks up those and takes them to a recycling plant.
then various types of paper are sorted by grade.
this is the third process.
getting the out of the paper fiber is the fourth and most important process.
this is called the deinking process.
all the ink on newspapers, scrap paper and even milk cartons needs to be removed.
it involves a difficult chemical and mechanical process.
the paper is washed with soapy water.
this removes the ink and any plastic coating or glue.
at this point, the paper is very wet and mushy.
the fifth process is putting this wet paper into a vast holding tank.
the staff at the recycling plant then adds different material to the wet paper.
this is how different types of new paper are made.
of course,A4 paper for computer printers needs to be a different thickness then that of paper grocery bigs.
the sixth process is spreading the types of paper onto large flat sheets.
the largest of these sheets will be used for newsprint to make newspapers.
the final process is the drying stage.
after that the paper is ready to be shipped.
by recycling paper, we can not only save trees, but also save energy.
making one roll of recycled newspapers uses 40-64 percent lass energy than going to the forest and cutting down another tree.
but there are limits to recycling paper.
after a piece of wood pulp paper is recycled 4-5 times, the individual fibers in the paper become too weak.
the recycled paper cannot be made into new paper products.
