  • Patent number: 9359482
    Abstract: A process for reducing the content of residual organic substances in mixtures of plastics from durable goods can include separating a feed stream into two or more mixtures of flakes and preforming a cleaning process to remove a portion of one or more of the absorbed organic substances from one or more of the mixtures. Each mixture can contain one or more plastic types and at least one organic substance absorbed into the one or more plastic types. The flakes in the mixtures can have an average particle diameter of less than 10 millimeters.
    Type: Grant
    Filed: August 1, 2012
    Date of Patent: June 7, 2016
    Assignee: MBA Polymers, Inc.
    Inventors: Brian L. Riise, Ron C. Rau, Michael B. Biddle
  • Patent number: 8450382
    Abstract: Techniques for creating recycled plastic materials from waste plastic materials are described. A recycled plastic material contains at least a primary polymer, a secondary polymer, and residual additives. Predetermined properties of the recycled plastic material can be controlled by selecting the types of waste plastic materials used in the recycling feed, determining the types and amounts of recycled plastic material recovered from a separation process and blending the recycled plastic material with other materials.
    Type: Grant
    Filed: February 7, 2011
    Date of Patent: May 28, 2013
    Assignee: MBA Polymers, Inc.
    Inventors: Brian L. Riise, Laurence E. Allen, III, Ron C. Rau, Michael B. Biddle

  • Patent number: 7802685
    Abstract: Multistep recycling processes for preparing recycled plastic materials. The processes feature a sequence of operations selected from the group consisting of preprocessing operations, size reduction operations, gravity concentration operations, color sorting, sorting by thickness, friction, or differential terminal velocity or drag in air, surface to mass control operations, separation processes enhanced by narrow surface to mass distributions, blending operations, and extrusion and compounding operations. Plastic-rich mixtures are subjected to the process, and one or more recycled plastic materials are collected as outputs of the sequence of processes.
