Poly(ethylene terephthalate) Film Recycling

Chemical Degradation of Poly(Ethylene Terephthalate)

The possibility of converting polyethylene terephthalate (PET) waste into terephthalic acid as a primary material by using different techniques through trans-esterification, with an alcohol and through hydrolysis in basic medium, has been investigated. In addition, utilization of activating agents such as inorganic salts and phase transfer catalysts has been investigated. Mineral water and beve...

Organocatalytic Depolymerization of Poly(ethylene terephthalate)

We describe the organocatalytic depolymerization of poly(ethylene terephthalate) (PET), using a commercially available guanidine catalyst, 1,5,7-triazabicyclo[4.4.0]dec-5-ene (TBD). Postconsumer PET beverage bottles were used and processed with 1.0 mol % (0.7 wt %) of TBD and excess amount of ethylene glycol (EG) at 190 C for 3.5 hours under atmospheric pressure to give bis(2-hydroxyethyl) tere...

Poly (ethylene terephthalate) recycling for high value added textiles

This study reviews the problems in the use and disposal of poly (ethylene terephthalate) (PET) and includes the concise background of virgin and recycled PET as well as their possible applications. The current state of knowledge with respect to PET recycling method is presented. Recycling of PET is the most desirable method for waste management, providing an opportunity for reductions in oil us...

Enzymatic surface modification of poly(ethylene terephthalate).

This study unambiguously confirms hydrolysis using cutinase of the persistent synthetic polymer poly(ethylene terephthalate), the most important synthetic fiber in the textile industry by direct measurement and identification of the different hydrolysis products. In this aqueous heterogeneous system, dissolved cutinase from Fusarium solani pisi acts on different solid poly(ethylene terephthalat...
