WASTE TIRE DETERMINATION METHOD, RECLAIMED MATERIAL MANUFACTURING METHOD, TIRE MANUFACTURING METHOD
A reclaimed material manufacturing method includes: step S11 of acquiring tire information concerning a waste tire (200); steps S12 to S17 of determining, based on the tire information acquired in step s11, whether or not a part or all of the waste tire (200) is suitable as a raw material for a predetermined reclaimed material; and a first manufacturing step of manufacturing the reclaimed material by using the part or all of the waste tire (200) determined in steps S12 to S17 as suitable as a raw material for the reclaimed material.
RECYCLED, THERMALLY STABLE POLYSTYRENE COMPOSITION AND PROCESS FOR PROVIDING SUPERIOR THERMAL STABILITY IN THE MECHANICAL RECYCLING OF POLYSTYRENE
The invention relates to a recycled, thermally stable polystyrene composition P, comprising a recycled polystyrene composition A, which comprises at least one polystyrene A-1 that is prepared by a thermally initiated and/or 1,1-bis(tert-butylperoxy)-3,3,5-trimethylcyclohexane initiated radical polymerization, and at least one sterically hindered phenolic antioxidant as component B. The invention also relates to a process for providing superior thermal stability in the mechanical recycling of polystyrene. Further, a recycled, thermally stable polystyrene composition P, a process for preparing the recycled, thermally stable polystyrene composition P and the use of the recycled, thermally stable polystyrene composition P for preparing molded articles are described.
Closed-loop recycling of scalable plastics
The present disclosure relates to a nontoxic poly(ethyl cyanoacrylate) (PECA) plastic. The PECA-based plastic is sourced from non-petroleum feedstocks and can be thermally and/or mechanically converted back to the ethyl cyanoacrylate monomer in a closed-loop recycling system with high monomer recovery. The disclosure also provides for methods of making the PECA plastics and methods of recycling the PECA plastics.
PROCESS AND PLANT FOR REMOVING DYES FROM WASTE TEXTILES
In a process for removing dyes from a waste textile material, including at least 50% by weight of polyester fibers, a batch of said textile material in an extraction chamber is extracted with a solvent that is circulated through the textile and the extraction chamber; said solution comprising solvent and extracted material is used as a solvent to extract dye from another batch of textile material, and in that said steps of extraction are repeated, until the amount of extracted material in said solution comprising solvent and extracted material reach a concentration whereby further dye extraction is impaired.
Processing petroleum-derived materials
A method of contacting petroleum-derived plastic materials with a lipid composition comprising fatty acid moieties, and an optional filler, to produce an agglomerate or a composite of the agglomerate, as well as an apparatus for carrying out the method and extruding the agglomerate or composite with a specific form or shape.
POLYAMIDE COMPOSITION PREPARED FROM A POWDER OF POLYAMIDES TO BE RECYCLED
The application relates to a method for preparing a polyamide composition, which comprises the steps of: a) providing a mixture comprising a virgin polyamide vPA and a polyamide to be recycled rPA in the form of an untransformed powder resulting from additive manufacturing by sintering or from a coating method by powdering or by electrostatic spraying, or powder obtained by grinding a polyamide-based part of an object to be recycled; b) kneading the mixture in the molten state, as a result of which a polyamide composition is obtained; and c) recovering the polyamide composition.
The invention also relates to the polyamide composition obtained and to the uses thereof for preparing articles by extrusion, injection or overmoulding.
