You can separate mixed plastics waste into its individual components with the hamos EKS electrostatic separators, as well as separating undesired plastic contamination. Using the hamos EKS, your mixed materials can be separated into pure sorted fractions with a minimum of effort by using the tribo-electric behaviour of the different plastics.
