Once Todd Waste Management have baled the cardboard it is then sent to paper mills to process. The mills break the cardboard down into a pulp and wash it to remove dirt and ink. The mills blend this pulp with fresher, stronger pulp made from wood chips. Machines dry and flatten this pulp mixture into new cardboard. The recycled cardboard can make new paperboard or both the outer lining and ribbed inner layer of corrugated cardboard. Once completed, the mills can ship the recycled cardboard off to manufacturing plants to make new boxes.
