Process for purifying mono-ethylene glycol

Abstract

The present invention relates to a process for purifying and recovering the mono-ethylene glycol (MEG) from a solution obtained from the depolymerization of at least one polyester having at least one unit of MEG. This solution is preferably obtained from an enzymatic depolymerization under alkaline conditions of polyethylene terephthalate (PET) included in a plastic product. The invention also relates to a process for recycling a polymer-containing material, such as plastic product, comprising at least one polyester having at least one unit of MEG, such as PET, and recovering the monomers thereof.
