It allows depolymerizing the PET plastic back to the original building blocks Terephthalic acid or its Ester (DMT) and Ethylene Glycol in smooth conditions and with a very reduced use of reagents and solvents. In Europe, we are the pioneers in adopting low carbon and economically viable eco-depolymerization chemical technology in PET recycling. The monomers thus obtained can give back virgin PET of food grade or any other premium quality in an infinite closed loop.
