Abstract: The present invention relates to processes for degrading plastic products and the uses thereof. The processes of the invention particularly comprise a step of amorphizing a plastic product prior to a step of depolymerization. The processes of the invention are particularly useful for degrading a plastic product comprising polyethylene terephthalate and/or polylactic acid. The invention also relates to a method of producing monomers and/or oligomers from a plastic product comprising at least one polyester, particularly polyethylene terephthalate and/or polylactic acid, comprising submitting the plastic product both to an amorphization step and to a depolymerization step.

Abstract: The invention relates to a method for recycling at least one mixed PET plastic article, the method comprising degrading at least PET of the mixed PET plastic article to monomers and/or oligomers using an enzyme and recovering the resulting monomers and/or oligomers. The method of the invention may be used for depolymerizing, simultaneously or sequentially at least two different polymers of the mixed PET plastic article, and/or for recycling at least two mixed PET plastic articles.
