Abstract

A method and apparatus for separating paper fiber from mixed waste materials which contain one or more sources of paper fiber in order to obtain substantially pure paper fiber which can be recycled to high grade end uses is disclosed. In addition, the process and apparatus separates plastic with or without metal in order to obtain substantially pure plastic which can be recycled to high grade end uses.
