Abstract

A method for treatment of electric and electronic scrap, in which method the scrap to be treated is crushed into particles of such size that each particle consists essentially or mainly of one material and the particles consisted essentially of plastic materials are selected for continued treatment, the particles are charged according to their triboelectric properties by rotating them (2) in a drum for rubbing them against the inner wall of the drum and each other and thereafter the particles are sorted (4) by means of an electric field, is characterised in that the material of the inner wall is selected to be a material from the upper end of the triboelectric series and said particles are before the sorting (4) additionally charged by bombing (3) them with electrons. The invention concerns also a corresponding apparatus.
