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 plastic product, the method comprising degrading at least one polymer of the plastic product to monomers using an enzyme and recovering the resulting monomers. The method of the invention may be used for degrading, simultaneously or sequentially at least two different polymers of the plastic product, and/or for recycling at least two plastic products.
