  • Systems and methods for recycling waste plastics
    Patent number: 12139671
    Abstract: Systems and methods for processing waste plastics are provided. One method includes mixing, heating and compacting a supply of the waste plastic based feedstock having an appreciable amount of halide compounds or heteroatoms from one or more sources of contamination; providing an amendment comprising alkaline earth oxides and/or hydroxides, oxides of iron, and/or oxides of aluminum to be mixed, heated and compacted with the waste plastic based feedstock to form a densified melt of plastic material including the amendment; and pyrolyzing the densified melt of plastic material including the amendment within a pyrolysis reactor. Another method includes pyrolyzing a supply of the waste plastic feedstock within a pyrolysis reactor to generate a hydrocarbon gas stream and a solids residue stream; condensing out a tars product from the hydrocarbon gas stream output from the pyrolysis reactor with a quenching apparatus; and pyrolyzing the tars product within a supplemental pyrolysis reactor.
    Type: Grant
    Filed: June 29, 2022
    Date of Patent: November 12, 2024
    Assignee: AGILYX CORPORATION
    Inventors: Sean Crawford, Barry Cavinaw
