Chemical Upcycling of PET Waste towards Terephthalate Redox Nanoparticles for Energy Storage

open access: yesSustainable Chemistry, 2021
Over 30 million ton of poly(ethylene terephthalate) (PET) is produced each year and no more than 60% of all PET bottles are reclaimed for recycling due to material property deteriorations during the mechanical recycling process.

Significance of poly(ethylene terephthalate) (PET) substrate crystallinity on enzymatic degradation

open access: yesNew Biotechnology, 2023
Poly(ethylene terephthalate) (PET) is a semi-crystalline plastic polyester material with a global production volume of 83 Mt/year. PET is mainly used in textiles, but also widely used for packaging materials, notably plastic bottles, and is a major contributor to environmental plastic waste accumulation.
