Abstract:
The invention relates to a method for the separation of a mixture of plastics, comprising several different types of plastic, by means of an electrical contact pre-treatment, which permits an increase in the ecological and economical efficiency and in the purity level of the separation. Said method comprises bringing the plastic mixture into contact with a pre-determined plastic type, whereby the plastic mixture is treated in such a way that a first group of plastics in the plastic mixture is essentially positively charged, a second group of plastics in the plastics mixture is essentially negatively charged and a third group of plastics in the plastics mixture is essentially uncharged. The third group of plastics is essentially the pre-determined plastic type.
