CHEMICAL RECYCLING OF PLASTIC DRY FINES
Processes and facilities for using one or more PET-containing materials as a feedstock to a chemical recycling facility, and in particular a solvolysis facility, are provided herein. The PET-containing materials used as feedstock may comprise a quantity of PET-containing dry fines. The PET-containing dry fines may be derived from various processes and facilities, including PET reclaimer facilities and/or manufacturers of PET articles. For example, the dry fines may be collected from solid-liquid separators and/or dust collectors from processes that include conveying, drying, densification, centrifugation processes, and/or grinding PET-containing plastic material. Such dry fines are generally undesirable or unusable to mechanical PET recycling facilities, and typically are sent to landfills and/or incinerators. However, the processes and facilities described herein make use of the PET and other plastics present in these otherwise undesirable or unusable dry fines.
METHOD FOR THE DEVULCANISATION OF A VULCANISAED RUBBER MIXTURE, DEVICE FOR CARRYING OUT THE METHOD, AS WELL AS A RUBBER MIXTURE AND VEHICLE PNEUMATIC TYRE, COMPRISING A COMPONENT MADE OF THE RUBBER MIXTURE
The invention relates to a process for devulcanizing a vulcanized rubber mixture, comprising the following steps: A) providing or producing a vulcanized rubber mixture, B) comminuting the vulcanized rubber mixture into a granulate of vulcanized rubber particles, C) extruding the vulcanized rubber particles produced in step B) in a twin-screw extruder to form a devulcanized rubber mixture, wherein, during the extruding in step C) at least one regeneration reagent is added to the extruded rubber particles, wherein the regeneration reagent comprises at least one silane, at least one plasticizer, at least one aging stabilizer or mixtures thereof. The invention also comprises an apparatus for performing the method and the uses of the apparatus, and a rubber mixture and also a pneumatic vehicle tyre or a technical rubber article comprising a component composed of the rubber mixture.
Polyester film and method for reproducing polyester container using same
The embodiments relate to a polyester film, which comprises a copolymerized polyester resin comprising a diol component and a dicarboxylic acid component and has a heat shrinkage rate of 30% or more in the main shrinkage direction upon thermal treatment at a temperature of 80° C. for 10 seconds and a melting point of 170° C. or higher as measured by differential scanning calorimetry, which not only solve the environmental problems by improving the recyclability of the polyester container, but also are capable of enhancing the yield and productivity, and a process for regenerating a polyester container using the same.

RECLAIMED MATERIAL FOR MANUFACTURING SHOES AND METHOD OF PRODUCING RECLAIMED RUBBER BY PROCESSING RECYCLED SHOE MATERIAL WASTE
A method of producing a reclaimed rubber made of recycled shoe material waste includes the following steps. Step S1: collect a scrap rubber which is the shoe material waste. Step S2: grind the scrap rubber to form scrap rubber granules. Step S3: devulcanize the scrap rubber granules to form a reclaimed rubber. A reclaimed material for manufacturing shoes includes a reclaimed rubber formulation and a crosslinking agent, wherein the reclaimed rubber formulation is constituted by compounding a basic rubber formulation and the reclaimed rubber, wherein the reclaimed material for manufacturing shoes includes 65-94.8 wt % of the basic rubber formulation, 5-30 wt % of the reclaimed rubber, and 0.2 wt % to 5 wt % of crosslinking agent. Mechanical properties of the reclaimed material for manufacturing shoes meet required standards of shoe outsole material. A method of consuming rubber waste produced during the shoe manufacturing process is disclosed herein.

METHOD FOR PRODUCTION OF ARTICLES AND SEMI-FINISHED PRODUCTS MADE OF CELLULOSE ACETATE
Method for production of articles and semi-finished products made of cellulose acetate, comprising the steps of recover-mg waste material consisting of cellulose acetate derived from previously made cellulose acetate articles and/or semi-finished products, distributing or positioning a mixture of at least one polymeric material inside a mould, heating and pressing the mixture inside the mould in order to form the articles or semi-finished products. The mixture is formed at least partially by the waste material consisting of cellulose acetate and the articles and/or semi-finished products may be subjected to a cooling and pressing step. The mixture is formed at least partially by fragments of cellulose acetate.

PROCESS FOR FEEDING PLASTIC WASTE MATERIAL TO A THERMOCHEMICAL OR PYROLYSIS REACTOR
Process for feeding plastic material, e.g. a plastic waste, to a processor such as a thermochemical reactor, e.g. a pyrolysis reactor. The process comprises an optional shredder or disintegrator (1), a conveying system (2), a feed hopper (3) with a lock hopper or rotary valve, a melting tank (6) with an agitator (5) followed by a melt pump (7) for the delivery of molten plastic to the processor. The advantage of the current process includes the ability to supply a consistent, metered flow to the processor, independent of the recycled plastic's melt properties, or the form or particle size and distribution of the plastic material.
