Enzymatic post-consumer poly(ethylene terephthalate) (PET) depolymerization using commercial enzymes [PDF]

open access: yes3 Biotech, 2023
Poly(ethylene terephthalate) (PET) is a synthetic polymer widely used globally. The high PET resistance to biotic degradation and its improper destination result in the accumulation of this plastic in the environment, largely affecting terrestrial and aquatic animals.

Microbial degradation and valorization of poly(ethylene terephthalate) (PET) monomers

World Journal of Microbiology and Biotechnology, 2022
The polyethylene terephthalate (PET) is one of the major plastics with a huge annual production. Alongside with its mass production and wide applications, PET pollution is threatening and damaging the environment and human health. Although mechanical or chemical methods can deal with PET, the process suffers from high cost and the hydrolyzed monomers ...

Marine hydrocarbon-degrading bacteria breakdown poly(ethylene terephthalate) (PET)

Science of The Total Environment, 2020
Pollution of aquatic ecosystems by plastic wastes poses severe environmental and health problems and has prompted scientific investigations on the fate and factors contributing to the modification of plastics in the marine environment. Here, we investigated, by means of microcosm studies, the role of hydrocarbon-degrading bacteria in the degradation of

Recycling of poly(ethylene terephthalate) (PET)

Makromolekulare Chemie. Macromolecular Symposia, 1992
AbstractAfter a survey of the mostly utilized recycling methods for fibres and bottles, the possibilities of recovering films are discussed in more detail. This presentation describes primarily the melt‐recovery method, which is used by us and by other manufacturers.

Finite strain behavior of poly(ethylene terephthalate) (PET) and poly(ethylene terephthalate)-glycol (PETG)

Polymer, 2005
Abstract Uniaxial and plane strain compression experiments are conducted on amorphous poly(ethylene terephthalate) (PET) and poly(ethylene terephthalate)-glycol (PETG) over a wide range of temperatures (25–110 °C) and strain rates (.005–1.0 s −1 ).

Migration of terephthalate from scraps of poly(ethylene terephthalate) (PET) in water and artificial seawater

Science of The Total Environment, 2022
We report the migration of terephthalate and some low molecular weight organic compounds from poly(ethylene terephthalate) (PET) scraps in Milli-Q water and artificial seawater (ASW). The photochemical processes and the subsequent dark reactions were investigated using PET scraps obtained from postconsumer bottles of commercial non‑carbonated mineral ...

Molar mass of poly (ethylene terephthalate) (PET) during ultimate uniaxial drawing

Polymer Engineering & Science, 2000
AbstractThe changes of the average molar mass Mw, Mn, Mz, and molar mass distributions during multistep uniaxial drawing of poly(ethylene terephthalate) (PET) to achieve ultimate mechanical properties have been studied in detail by means of size exclusion chromatography (SEC) with triple detection: concentration, viscosimetry, and light scattering ...
