In a method for reprocessing plastic waste material, in embodiments PET waste material, the plastic waste material is dried by a flash dryer in a conveying line and then fed into a multi-shaft screw machine. In the multi-shaft screw machine, the dried plastic waste material is reprocessed. Pre-drying enables simple, energy-efficient, economical, reliable and effective reprocessing.

Provided is a method for producing recycled pellets, capable of using loss films that have been inapplicable so far including a thick loss film, a wide loss film, and a loss film made of a material that has high hardness and therefore is less likely to be bent, and also capable of producing recycled pellets similar to virgin pellets. A method for producing recycled pellets includes the steps of: twisting one or more loss films (R) continuously supplied in one direction while applying a stretch to the loss film; pressurizing a twisted part to pressure-bond contact parts of the loss film (R), thereby forming a twisted string (R); and cutting the twisted string (R) to produce recycled pellets (P). The loss film (R) is preheated at a softening temperature of the loss film (R) prior to twisting the loss film (R) while stretching it.

The present invention provides a flame-retardant styrene polymer composition comprising an organic bromine compound, zinc stearate and calcium stearate, the use for preparing styrene polymer films or foams and a process for recycling of styrene polymer-containing scrap.

A system and method for processing an artificial turf, and a product produced by the method, is provided. The method includes providing an artificial turf having an infill, separating at least a portion of the infill from the artificial turf, downsizing the artificial turf into artificial turf fragments and rotationally mixing and translating, by a melt system, the artificial turf fragments at a pressure less than a maximum predefined pressure to form a melt. The maximum predefined pressure is between about 0.08 - 20 bar.

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.

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.

The present invention provides an apparatus for recycling composite material and a method for recycling composite material by using same, the apparatus including: a mixing tank in which pulverized products of fiber-reinforced waste plastic are dispersed and mixed in water together with a filler, thereby forming a composite material mixture; a fixing agent addition part for forming a recyclable material by supplying, to the composite material mixture, a fixing agent that aggregates the pulverized products of the fiber-reinforced waste plastic and the filler; and a filtering tank in which the recyclable material is supplied such that a recyclable composite sheet is formed.

A process for the segregation, sterilization, and purification of recycled plastic medical waste with the subsequent production of plastic products made therefrom is disclosed. Also disclosed is a method for the front-end segregation of recycled plastic medical waste into a polypropylene waste stream and a mixed plastic waste stream. These segregated streams are further purified through a processing method that removes contaminating fibrous, metal and other waste products. Polypropylene and mixed plastic streams isolated using these methods yield a homogenous material that can be blended with other materials for the production of raw plastic or for extrusion to form commercial plastic products. A method for tracking regulated and non-regulated medical waste stream production kinetics and chain of custody from discrete waste disposal sites is also disclosed.

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.

The invention relates to the manufacture of hollow objects made of plastics material by way of an extruder. In order to improve the quality of the manufactured objects and the regularity of manufacture, the extruder that is fed at least with the initial metered quantity and to which at least a part of the molded blanks and/or of the molded and heated blanks used for manufacturing said objects and/or of the finally manufactured objects will be recycled is a twin-screw extruder.
