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 present invention relates to novel esterase, more particularly to esterase variants having improved activity compared to the esterase of SECS ID NO: 1 and the uses thereof for degrading polyester containing material, such as plastic products. The esterases of the invention are particularly suited to degrade polyethylene terephthalate, and material containing polyethylene terephthalate.
