Why does paper need to be sorted before it’s recycled?
Successful recycling requires clean recovered paper which is free of contaminants such as food, plastic, metal, and other trash. Contaminated paper can introduce impurities and bacteria into the recycling process. Furthermore, different grades of paper – corrugated boxes, newspapers, and office paper – must be kept separate, because the different grades of recovered paper are used to make particular types of recycled paper products.
