Abstract

The present invention concerns a method for the selection and separation of polymers originating from urban and/or industrial plastic waste to obtain plastic materials for recycling which comprises a first step of supplying a mixture of polymers composed of flakes of polymers having dimensions ranging from 6 to 100 mm; a step of identification by means of near-infrared (NIR) spectroscopy of the flakes of coloured and white plastic material and the flakes of black plastic material and subsequent separation from one other; several consecutive steps of identification by means of NIR spectroscopy of the different types of polymer from the coloured and white plastic material and subsequent separation of said polymer types.
