Synergistic chemo-enzymatic hydrolysis of poly(ethylene terephthalate) from textile waste.

ABSTRACT: Due to the rising global environment protection awareness, recycling strategies that comply with the circular economy principles are needed. Polyesters are among the most used materials in the textile industry; therefore, achieving a complete poly(ethylene terephthalate) (PET) hydrolysis in an environmentally friendly way is a current challenge. In this work, a chemo-enzymatic treatment was developed to recover the PET building blocks, namely terephthalic acid (TA) and ethylene glycol. To monitor the monomer and oligomer content in solid samples, a Fourier-transformed Raman method was successfully developed. A shift of the free carboxylic groups (1632 cm^-1 ) of TA into the deprotonated state (1604 and 1398 cm^-1 ) was observed and bands at 1728 and 1398 cm^-1
