  • Method and apparatus for color removal from PET-flake (shredded PET)
    Patent number: 9890261
    Abstract: Organic colorants incorporated in colored PET-flake, as being obtained by shredding PET bottles, can be extracted from the PET-flake by extracting the PET-flake with ethylene glycol (EG) at ambient pressure and at the boiling temperature of EG. Pre-treating of PET-flake in EG or other suitable organic compounds prior to extraction enhances the discoloration.
    Type: Grant
    Filed: September 23, 2015
    Date of Patent: February 13, 2018
    Assignee: OXXYNOVA GMBH
    Inventors: Katharina Besse, Thomas Rieckmann, Samantha Walter

  • Method and device for the decontamination of plastic flakes
    Patent number: 8557882
    Abstract: A method for preparing contaminated plastics ground into flakes, such as RPET or such polymers, having at least decontamination and SSP treatment steps, with at least one reactor, with heating to the process temperature taking place essentially outside the reactor. Also, a device for carrying out the method, and having at least one decontamination reactor and at least one SSP reactor, a device for heating plastic flakes to the process temperature being arranged upstream of the decontamination reactor. Also an SSP reactor having at least two individual reactors, and preferably between 3 and 7 individual reactors.
