  • TREATED WASTE PLASTIC MATERIALS
    Publication number: 20260015480
    Abstract: Quantities of plastic solids derived from mixed plastic waste are provided. The quantities can comprise polyolefins and/or polyethylene terephthalate and can be co-located with other quantities of plastic solids. The quantities of solids plastics can comprise particulate plastic solids that are suitable for use as feedstocks to various chemical recycling processes.
    Type: Application

    Publication date: January 15, 2026
    Applicant: Eastman Chemical Company
    Inventors: Bruce Roger DeBruin, Kyle Lyn Collings, Robert Ryan Stanley
  • Particulate plastic solids handling apparatus and methods
    Patent number: 12515377
    Abstract: Facilities and systems for handling of particulate plastic solids obtained from a mixed waste plastic separation system are provided. The facilities comprise at least one enclosed structure and an elongate overhead conveyor associated with the at least one enclosed structure that is configured to selectively deposit the particulate plastic solids into a plastic solids transport system that interconnects the handling facility and a plastic chemical recycling facility and/or at least one inventory pile within the at least one enclosed structure.
    Type: Grant

    Assignee: Eastman Chemical Company
    Inventors: Bruce Roger DeBruin, James Stewart Nelson, Brandon G Head, Robert Ryan Stanley
  • Treated waste plastic materials
    Patent number: 12454604
    Abstract: Isolated quantities of plastic solids having greater than 70% by weight polyethylene terephthalate (PET) also include a) from 0.1% to 10% by weight polyvinyl chloride (PVC), and a moisture content of less than 4% by weight, or b) from 0.05% to 10% or 0.1% to 4% by weight halogens, or c) from 0.1% to 4% by weight polyvinyl chloride (PVC), and at least 0.1% by weight of solid materials that do not phase change below 270° C. and 1 atm. The quantities of these solid plastics are suitable for use as feedstocks to various chemical recycling processes.
