20080234399 | Process For the Recycling of Plastics - Process for recycling soluble or dispersible plastics from a waste product containing plastics by treatment with an organic solvent, concentrating the plastics solution thus obtained to more than 40 wt % of plastics, preconditioning the concentrated plastics solution to a pressure of at least 2 bar using a first pump and a temperature of 1-10° C. below the boiling temperature of the solvent at that pressure, bringing this preconditioned concentrated plastics solution above the critical point of the plastics solution using a high-pressure pump and a high-pressure heat exchanger, spraying the concentrated plastics solution above the critical point to recover the plastics through evaporation of the organic solvent, and recovery of the organic solvent. The process has advantages over known processes in that higher concentrations of plastics can be processed, without the danger of cavitations, and the need for solvent and energy can be reduced. | 09-25-2008 |
20090069453 | SYSTEM FOR RECYCLING A USED PLASTIC, METHOD FOR REPROCESSING A USED ABS RESIN, AND RECLAIMED ABS RESIN - A system to recycle plastics, which enables a supply of recycled plastics having a stable quality required for the recycled products. A system to recycle a used plastic material as a resin material including (a) means to sort used plastic materials for the purpose of recycling said used plastic materials, (b) means to crush and melt said used plastic material after it has been sorted, (c) reviving means to regain a desired property, and (d) means to measure a physical property of a reclaimed plastic after it has been revived and to indicate said measured physical property for quality assurance. | 03-12-2009 |
20090221727 | Composition and Process for Conversion of Paint Sludge Into Reusable Paint - The present invention relates to a composition for the conversion of paint sludge into reusable paint, to a process for the preparation of said composition and to a process for the conversion of waste paint sludge back to useful paint. The sludge conversion process of the invention consumes the environmentally hazardous sludge collected from paint application systems by converting this paint sludge into a reusable paint. | 09-03-2009 |
20090239961 | Recycling - A process for recycling a coloured thermoplastic material comprising an absorbed disperse dye comprises contacting the optionally comminuted coloured thermoplastic material with a caustic wash and recovering an at least partly colour-modified thermoplastic composition from the caustic wash. | 09-24-2009 |
20100099781 | RECYCLING SUPERABSORBENT POLYMER FINES - 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. | 04-22-2010 |
