It’s essential that newspaper is clean and dry when it’s sent for recycling. The top contaminants of newspapers include:
Food waste
Body fluids like blood
Chemicals
Paints
Coffee
Oil or grease
When any of these materials contaminate your newspapers, it could be impossible to recycle them. This is because when newspapers are recycled, they’re made into new materials. It’s almost impossible to remove any contaminants. For example, if your newspapers are contaminated with blood, there’s a health risk to the public if they’re recycled to make other products.
