Efficient Depolymerization of Polyethylene Terephthalate Waste via Mechanocatalytic Methanolysis Using the K2CO3 Catalyst
Tackling plastic waste has garnered growing attention in recent years, spurring intensified research into plastic depolymerization. Among various plastics, polyethylene terephthalate (PET) stands out as the most widely recycled. Although several depolymerization methods have been reported, many still rely on high tem...

Multifactor Optimization of Solvolytic Recycling of Polyethylene Terephthalate in Designer Deep Eutectic Solvents
A circular economy for polyethylene terephthalate (PET) aims to achieve complete material recirculation and reduce dependence on fossil-based feedstocks. Among recycling strategies, depolymerization offers the greatest potential for true circularity. This work investigates deep eutectic solvent (DES)-assisted PET depol...

Hydrodeoxygenation of Mixed Plastic Wastes Towards Aviation Fuels over Ni−Re Alloy Catalyst
To address the challenge of mixed plastic waste management, we present a one-pot hydrodeoxygenation (HDO) process that selectively converts mixed oxygenated aromatic plastics including polyethylene terephthalate (PET), polycarbonate (PC), polyphenyl ether (PPO), and bisphenol-A-based epoxy resin (E20) into high-value...

Molecular Recycling of Polyethylene Terephthalate (PET) Waste via Ytterbium Triflate-Catalyzed Hydrolysis
Returning waste polyethylene terephthalate (PET) to its original monomers (e.g., terephthalic acid (TPA)) constitutes closed-loop molecular recycling. Hydrolysis can accomplish this conversion and ytterbium triflate (Yb(OTf)3) is an effective catalyst. PET hydrolysis with Yb(OTf)3 at 220 °C for 40 min resulted in 92% P...

Sustainable Electrosynthesis of Hexamethylenetetramine via Paired Electrolysis of Nitrate and PET Waste.
Hexamethylenetetramine (HMTA) is a critical organonitrogen compound widely used in the defense, pharmaceutical, and polymer industries. Conventional HMTA production relies on toxic formaldehyde (HCHO) and energy-intensive Haber-Bosch-derived ammonia (NH3) as feedstocks. This study demonstrates a sustainable electrocata...

Electrophilic substitution in poly(ethylene terephthalate) waste for upcycling to functional metal–organic frameworks
In contrast to polymer-to-polymer recycling of waste polyethylene terephthalate (wPET), chemical upcycling into added-value molecules beyond terephthalic acid is a promising strategy. Among possible transformations, electrophilic substitution offers a direct path, yet has remained unrealized due to the electron-deficie...
