  • Patent number: 11981779
    Abstract: A process and a system for depolymerizing plastic, such as waste polyester, into marketable monomers. A heterogeneous mixture of plastic particles, a solvent, and a catalyst are pumped continuously through a heating zone at a flow rate just high enough to maintain a particle speed great enough to keep the plastic particles in suspension. The temperature of the heterogeneous mixture is raised in the heating zone and maintained in a hold zone to complete depolymerization of the mixture into a homogeneous solution containing a liquefied plastic monomer. The homogeneous solution is cooled to solidify and precipitate the monomer. The precipitated monomer is separated from the solvent to be recycled. The solvent is recirculated to be reused as a constituent of the heterogeneous mixture.

  • Patent number: 11970586
    Abstract: A composite material may be prepared from a solid polymeric binder and a solid filler by feeding into an extruder the solid polymeric binder at a first feed rate and the solid filler at a second feed rate. The extruder extrudes an extrudate of the solid polymeric binder and solid filler to form the composite material. The composite material has a binder to filler ratio determined by the first feed rate and second feed rate. The solid polymeric binder and solid filler have different densities. Feeding the solid polymeric binder at the first feed rate and the solid filler at the second feed rate distributes the solid filler substantially homogeneously throughout the composite material.
