They have a regular magnet that picks up iron related material. Then the mixture of plastic and glass goes through a rotating metal tube with holes the size of glass bottles while a strong fan blows the lighter plastics to another belt. Most plastic and aluminum ends up on this last belt. The plastic was sorted by hand while a special magenet repelled the aluminum into its own bin. The machine was an old one, and newer machines sort more, faster, and with fewer people. Progress?
