A small hole is made in the center by a machine, and air is blown into the bottle to hollow it out. A neck is shaped for a cap or lid. Annealing oven, or leer, slowly heats, then cools, the glassware, which makes it strong. Cans are smashed and cut into dime-size shreds. Shreds are placed in a gas-powered aluminum furnace, making liquid metal.
Liquid flows into molds that form ingots, or bars of metal.
Rollers squeeze the ingots into sheets for new cans. Sheets are rolled into coils and sent to a plant, where they are shaped into cans again. All Rights Reserved worldwide.
