    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: 8153699
    Abstract: A surfacing composition made of recycled paint, which requires no priming, has a non-reflective “flat” appearance, and is partially composed of dried paint. The composition provides a useful application for used or excess household paint, which would otherwise require special methods of disposal and potentially create future toxic cleanup problems. The composition is made of granular dried paint and a water-based sealer, which can be spread on a surface to repair imperfections. The surface can then be finished, and no priming is required. Due to the composition's flat appearance, the patch does not display any characteristic sheen where the repair has been made. The composition provides a simple means of recycling paint, and provides a simple and inexpensive means of repairing imperfections in walls and other surfaces while saving the step of priming the patch before painting or repainting.

  • Patent number: 7547734
    Abstract: Recycled resin is produced by a method including a dismantling/recovery step of dismantling products containing resin moldings and recovering the resin moldings, a removal step of removing unwanted matter including metal components from the resin moldings, a sorting step of discriminating the materials of the resin moldings, and a crushing step of crushing the resin moldings. The method further includes, prior to the crushing step, detecting the metal components, and, after the crushing step, separating out and thus removing metal remaining in crushed material.

  • Patent number: 7452918
    Abstract: A recycled plastic material is made from laser-engraved thermoplastic, metal-containing thermoplastic, thermoplastic used in an inkjet apparatus, or thermoplastic to which an ink or its composition have stuck. This recycled plastic material is manufactured by pulverizing any of these thermoplastics, cleaning the pulverized thermoplastic, removing a cleaning solution from the cleaned thermoplastic to dry it, and removing the dried thermoplastic solid matter other than the thermoplastic.

  • Publication number: 20080132591
    Abstract: A method of producing a thermoplastic polyurethane (TPU) compound including a polyurethane powder comprising microcellular polyurethane (MCU). The method minimizes discarding scrap MCU, reduces the cost of TPU articles by introducing a partial replacement for the TPU resin, and reduces injection-molding times to produce TPU articles. The TPU compound including polyurethane powder has superior melt temperature and compression set properties as compared to TPU compounds of similar Shore hardness that are free of the polyurethane powder. The invention also provides a TPU article including the TPU compound and a method of recycling a MCU foam.

  • Patent number: 7138435
    Abstract: A method of decomposing a thermosetting resin by a decomposer comprising the steps of: pre-heating the thermosetting resin up to a pre-heating temperature T0; kneading the pre-heated thermosetting resin together with a decomposer, and concurrently heating a mixture comprising the thermosetting resin and the decomposer up to a kneading temperature T1, thereby allowing a reaction to take place between the decomposer and the thermosetting resin to obtain a kneaded matter wherein the decomposer becomes consumed; and heating the kneaded matter to a maximum temperature T2 to thereby decompose the thermosetting resin; wherein the preheating temperature T0 is not higher than the boiling temperature of the decomposer; the kneading temperature T1 is not lower than the pre-heating temperature T0 but is lower than the thermal decomposition temperature of the thermosetting resin; the maximum temperature T2 is lower than the decomposition temperature of the thermosetting resin; and the pre-heating of the thermosetting resi

  • Patent number: 7056956
    Abstract: Process for recycling a plastic, according to which the plastic is brought into contact with a solvent capable of dissolving the same and the plastic dissolved in the solvent is precipitated using a non-solvent in the presence of a phase-separating agent, in which the phase-separating agent is compatible with the solvent and incompatible with the non-solvent, and is also present when the plastic is brought into contact with the solvent, and improves the dissolution of the plastic by the solvent.

  • Patent number: 6837950
    Abstract: The invention relates to methods for processing floor coverings (100), such as carpet and/or carpet tile, having at least one layer containing a polyurethane (104), such that at least this polyurethane—containing layer (104) can be recycled and reused. The method involves contacting the floor covering (100) with an organic polyol (110) and heating (120) it, so that the polyurethane—containing layer (104) softens and/or partially liquefies, but can be resolidified by contact with additional polyisocyanate (140).
