  • Patent number: 11008433
    Abstract: A method for separating and purifying polymers of a reclaimed product (rP) is disclosed. The rP is contacted at an elevated temperature and pressure, with an extraction solvent to produce an extracted rP (erP). A solvent, at conditions sufficient to solubilize the first polymer, contacts the erP to produce a solution, which is purified at an elevated temperature and pressure by filtering it and contacting it with a solid medium to produce a purified solution of the first polymer. The purified polymer is then separated from the purified solution, and the method steps are repeated until all polymers are separated and purified.

  • Patent number: 8546455
    Abstract: The invention relates to a method of solubilizing expanded polystyrene (EPS), in which the EPS is brought into contact with at least one initial solvent, enabling the transition of the EPS from an expanded solid state to the gel state. The aforementioned gel is subsequently treated with at least one complementary solvent that is different from the initial solvent, enabling the solubilization thereof such as to produce a true solution. The invention also relates to the product thus obtained and to the use of said product.

  • Patent number: 8536238
    Abstract: A process for the preparation of thermal insulation sheets fashioned from certain unseparated mixtures of post-consumer plastic articles is disclosed. The mixtures of such articles contain polyethylene terephthalate (PET) and polystyrene (PS) and optionally also articles made of high density polyethylene (HDPE). An unseparated mixture of such articles is provided. This mixture is crushed and shredded to form plastic flakes, and these plastic flakes are then homogenized. Homogenization of the flakes can be carried out either by melt-blending them or by further comminution to produce very fine particles of the mixed plastics. The resulting homogenized mixture of plastic types is then compression molded into sheets.

  • Patent number: 8530531
    Abstract: Method for the recycling of polyvinyl butyral based on obtaining recycled polyvinyl butyral (PVB) from laminated glass which is shattered and the polyvinyl butyral (PVB) is separated. The sheet obtained is cut into pieces and cleaned to eliminate dirt and foreign matter. The solid state PVB is subjected to a first polyvinyl butyral (PVB) purification stage with a chemical treatment with a first reagent and a final chemical treatment with a second reagent. The obtained purified polyvinyl butyral is suitable to be used in the manufacture of laminated glass.

  • Patent number: 8487049
    Abstract: A process is described for recycling superabsorbent polymer fines into a process that includes treating the superabsorbent polymer fines with caustic and a polymerization step for making the superabsorbent polymer gel. The process requires treating the superabsorbent polymer fines with a caustic, followed by mixture with polymerizable monomer solution, and polymerizing the mixture of the superabsorbent polymer fines and monomer to form the aqueous fluid absorbent polymer. In the process, the fines are incorporated into the new polymer gel and become indistinguishable there from. The gel may then be comminuted into a particulate dried and then separated into a portion having a desired minimum particle size in a fines portion having less than the desired size. The particulate may then be coated with a surface crosslinking agent and surface additives and heated for surface conversion.

  • Patent number: 8466205
    Abstract: The present invention pertains to carpet and methods of making and recycling carpet. In one aspect, the carpet includes: a primary backing which has a face and a back surface; a plurality of fibers attached to the primary backing and extending from the face of the primary backing and exposed at the back surface of the primary backing; an adhesive composition backing; and an optional secondary backing adjacent to the adhesive backing. The method of making carpet includes extrusion coating the adhesive composition onto the back surface of a primary backing to form the adhesive composition backing. The method of recycling carpet can recover one or more polymeric carpet components.

  • 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.
