  • Patent number: 10864712
    Abstract: A method for laminating profile and plate materials produced from processed mixed plastic waste and other plastic surfaces comprises steps of collecting and processing of mixed plastic waste for recycling for making profile and plate materials and lamination of profile and plate materials produced from processed mixed plastic waste, wherein the lamination of profile and plate materials produced from processed mixed plastic waste comprises stabilizing the profile temperature before lamination; determining the surface quality; making the surface quality of profile suitable by propane gas treatment of the profile; heating the profile surface before the lamination process; heating the adhesive right before the lamination; applying the adhesive to the laminate surface; carrying out the lamination process; and directing the laminated profiles for storying.

  • Patent number: 10301448
    Abstract: A process for making polymer composition from mixed plastic waste is disclosed. The composition comprises plastic waste of different types obtained from recycled unidentified, uncleaned, unsorted, compacted and homogenized plastic waste. Preferably the plastic waste comprises polyethylene (PE), approximately 50-60% of its total volume; polypropylene (PP), approximately 20-30% of its total volume; polystyrene (PS), approximately 5-10% of its total volume; a mixture of unidentified plastic and other materials, approximately 1-10% of its total volume. The mixture of unidentified plastics comprises polyamides (PA), Polyethylene terephthalate (PET), Polyacetal (POM), and Polycarbonate (PC).

  • Patent number: 9815225
    Abstract: A blade system for device for recycling mixed plastic is disclosed. Furthermore, a device and a method for recycling unidentified, unclean, and unsorted mixed plastic into reusable plastic mixture is disclose. The present solution allows the recycling of mixed plastic waste outdoors, both in warm and cold climate conditions. In the course recycling mixed plastic waste the mixed plastic waste is taken to a melting temperature, at which the mixed plastic waste is mixed in a molten state, and the organic and bacterial material is destroyed during the thermal processing. After the melting, mixing and thermal processing of the mixed plastic waste, the compaction process of the molten mixed plastic waste is performed. Volume compacting is performed, and the mass of mixed plastic waste in a molten state is rapidly cooled down, crushed, after-cooled and homogenized.
