Paper is sorted by type and sent to a paper mill. Hydrapulper cooks the paper until it is a thick soup of fibers. Detergents and chemicals remove inks. The paper is now pulp, which looks like cottage cheese. Impurities are removed by a moving screen, spinners, and a series of washers.
Pulp is bleached with chlorine to make it white and washed again.
Machine rolls out pulp and dries new paper. Paper is cut to size, wrapped, and shipped. Cullet is dropped into weighing bin along with ingredients to make new glass. Bottle-size portions flow down a chute into molds, where they are shaped and cooled. A small hole is made in the center by a machine, and air is blown into the bottle to hollow it out.
