The present disclosure relates to degradation of polymer materials, such as plastic materials. More specifically, the present disclosure relates to a method for digestion of one or more plastic-comprising material by the use of at least one larva of the species selected from the group consisting of Galleria mellonella, Tenebrio molitor and Alphitobius diaperinus. The product obtained by the method is also within the inventive concept. The disclosure furthermore relates to use of said at least one larva for digestion of a plastic-comprising material.

The present invention relates to a chemical and biological integrated degradation process for PET, for recycling PET, and, more specifically, the present invention provides a PET upcycling technique for producing a high-value product via a chemical pretreatment process of PET, a TPA and EG production process using an enzyme, and a process for converting TPA and EG to PCA and GLA, respectively.

The present invention relates to a method for treatment of polyhydroxyalkanoate (PHA) containing post-consumer product, the method comprising contacting a post-consumer product with a polypeptide that can catalyze degradation of the PHA, the contact taking place at a temperature at least 45? C. In a specific embodiment, the poly peptide is a wild-type PHA depolymerase expressed by a thermophilic microorganism or a modified PHA depolymerase that includes one or more single-site mutations as compared to the wild-type PHA depolymerase. In another specific embodiment, the polypeptide comprising a modified poly hydroxy butyrate (PHB) depolymerase comprising one or more single-site mutations as compared to SEQ ID NO: 1, and the modified PHB depolymerase having an optimum temperature of at least 45? C. The present invention also relates to a host cell transformed to express a polypeptide that catalyzes degradation of a PHA, the polypeptide having an optimum temperature for the degradation reaction of at least 45? C., wherein the host cell is selected from an E. coli cell or a thermophilic microorganism.

A method for processing plastics includes receiving input plastics to be processed. The method further includes driving the input plastics through a reactor chamber having at least two zones each containing heated fluid that is heated to greater temperatures in a subsequent zone such that remaining plastics of the input plastics are exposed to increasingly greater temperatures in each zone of the reactor chamber. The method also includes collecting condensable vapors that flow out of the at least two zones of the reactor chamber. The method further includes condensing the condensable vapors into a liquid condensate. The method also includes removing biochar products from the heated fluid. The method further includes removing contaminants from the reactor chamber.

Apparatus, systems (including solvent or enzyme), and methods of degrading plastic are described. Plastic waste is stretched in the presence of solvent. The surface may be further treated to increase hydrophilicity. The resulting plastics can be treated with plastic-degrading enzyme either with microorganisms or direct application of enzyme.

A process of treatment of waste blend textiles comprising polyester fibers and cotton fibres depolymerizes polyester in a controlled environment to obtain treated textile comprising cotton staple fibers suitable to be recycled into cotton yarns.

The present disclosure relates to the production of biomass from at least one plastic polymer. More specifically, the present disclosure relates to use of a feed for production of biomass, wherein larvae of the family Pyralidae or of the family Tenebrionidae are fed on a feed comprising at least one plastic polymer, a related use of increasing pupation in a population of larva.

A recycled-carbon-fiber tow composition comprising a recycled carbon fiber tow taken from a carbon-fiber-reinforced thermosetting resin molded body; and a surface modifier having a chemical functional group (hereinafter, referred to as second chemical functional group) that has chemical affinity with a chemical functional group (hereinafter, referred to as first chemical functional group) existing on a surface of the carbon fiber, wherein the recycled carbon fiber tow is formed such that carbon fibers are bundled into a tow with amorphous carbon that substantially contains no resin residue, the recycled-carbon-fiber tow composition contains 0.1 to 1 weight % of the surface modifier when an entirety of the recycled-carbon-fiber tow composition is 100 weight %, and n amount of residual carbon content measured when the recycled-carbon-fiber tow composition has been heated in a condition of 600? C.?60 minutes is 1 to 5 weight %.
