  • 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).
