Development of Primer as a Value Added Product from Waste PET
Abstract: Polyethylene terephthalate was depolymerized by two different chemical recycling techniques i.e. glycolysis and aminolysis. Glycolysis is carried out with Zinc hydroxide and with conventional catalyst i.e. Zinc acetate for the comparable yield of the monomer. Glycolysis is carried out with ethylene glycol whereas aminolysis is done with ethanolamine. Products obtained from both the techniques namely Bis(2-hydroxyethyl) terephthalate (BHET) and Bis(2-hydroxyethyl) terephthalamide (BHETA) have different chemical structure but have hydroxyl functionality …

AI-Assisted Kinetic Modeling of PLA Hydrolysis Under Subcritical Water Conditions for Sustainable Polymer Recycling
Abstract: The accumulation of poly (lactic acid) (PLA) in terrestrial and marine ecosystems has intensified the demand for closed-loop, green recycling technologies. Subcritical water (SCW) hydrolysis offers a promising, catalyst-free pathway for the rapid depolymerization of PLA into its constituent monomer, lactic acid. However, the complex, highly non-linear kinetics governing macro-molecular degradation under variable hydrothermal conditions limit real-time process optimization and industrial scalability. This study develops a novel artificial intelligence (AI)-assisted …
