To provide a method and an apparatus for feeding and carrying a ground plastic simply, inexpensively in a high separation accuracy and to provide an electrostatic separator for a ground plastic.

This separator exhibits an improved separation accuracy by comprising a passage 6 carrying plastics and formed by connecting an air blowing means 1, a heating means 2, and the feed path 5 of a feed means to each other; a means that charges the plastics during their conveying; an electrostatic separation means that separates the plastics according to their types; a plurality of recovery receivers disposed below the electrostatic separation means; a means that decreases the rate of the plastics fed to the electrode, a feed position regulation means, etc.
