Abstract
A method for recycling polyester containers, in particular PET containers, said method including the following method steps: sorting the containers, comminuting the containers to produce flakes, friction washing the flakes, sorting the flakes, and extruding and granulating the cleaned flakes. The flake-sorting process is used to separate flakes which have a foreign polymer that is different from the polyester, and the flake-sorting process is a combination of a color-sorting process, a screening step, and polymer-sorting process.
