The recycling of post-consumer PET (POSTC-PET) as a technology is a cross-disciplinary practice with many fields of science involved. These include polymer chemistry and physics, process engineering and manufacturing engineering. This paper presents a concise background of the current state of knowledge with respect to POSTC-PET recycling covering the disciplines mentioned above. In the first s...

BACKGROUND, AIMS, AND SCOPE Heavy metal contaminants in environment, especially in drinking water, are always of great concern due to their health impact. Due to the use of heavy metals as catalysts during plastic syntheses, particularly antimony, human exposure to metal release from plastic bottles has been a serious concern in recent years. The aim and scope of this study were to assess metal...

Chemical recycling to monomers is one of the key strategies in tackling issues deriving from persistent plastic pollution environment, and poly(ethylene terephthalate) (PET) among most used polymers modern society. In this context, we herein describe glycolysis PET bis-hydroxyethyl terephthalate (BHET), promoted by basic cholinium salts differing for anions, also comprising amino acid anions. W...

absorption of flavor compounds from food into the package is one of the interactions which occurbetween food and packaging material. this phenomenon is of high importance, because absorptionof flavors into the packaging material could diminish the flavor intensity of the product as well asloss of mechanical/border properties of the packaging material, so the final loss of quality in thefood pro...

The increasing amount of marine plastic waste poses challenges including, not only the collection, but also subsequent recyclability plastic. An artificial accelerated weathering procedure was developed, which modelled environment and investigated weathered non-weathered PET. Marine conditions were simulated for poly(ethylene terephthalate) (PET) bottle material high-density polyethylene (HDPE)...
