Hydrocarbon-associated substrates reveal promising fungi for poly (ethylene terephthalate) (PET) depolymerization [PDF]

Brazilian Journal of Microbiology, 2019
Recalcitrant characteristics and insolubility in water make the disposal of synthetic polymers a great environmental problem to be faced by modern society. Strategies towards the recycling of post-consumer polymers, like poly (ethylene terephthalate, PET) degradation/depolymerization have been studied but still need improvement. To contribute with this

From Plastic Waste to Pharmaceutical Precursors: PET Upcycling Through Ruthenium Catalyzed Semi-Hydrogenation. [PDF]

Angew Chem Int Ed Engl
We present a new catalytic process that converts real‐life PET waste into ethyl 4‐hydroxymethylbenzoate (EHMB), which serves as a valuable intermediate for the synthesis of pharmaceuticals, an insecticide, and a novel polyester. Abstract We report here the upcycling of PET (polyethylene terephthalate) waste via semihydrogenation to make ethyl 4 ...

Novel terephthalamide diol monomers synthesis from PET waste to Poly(Urethane acrylates)

Frontiers in Chemistry, 2023
Due to its excellent properties, poly(ethylene terephthalate) (PET) is one of the most produced and consumed polymers. Among plastics, it represents the main contributor to environmental pollution.
