Abstract
Abstract A method and apparatus for recycling cans is disclosed. Magnetic material comprising mostly steel cans is separated from a material input. Conductive material, comprising mostly aluminum cans, is then separated from the balance of the material input. The conductive material is weighed and paid for and the magnetic material and conductive material are recombined for storage.
