Abstract: The present invention relates to novel esterase, more particularly to esterase variants having improved thermostability compared to the esterase of SEQ 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.

Abstract: La presente invención se refiere a procesos para degradar productos de plástico y a los usos de los mismos. Los procesos de la invención comprenden en particular una etapa de amorfización de un producto de plástico antes de una etapa de despolimerización. Los procesos de la invención son particularmente útiles para degradar un producto de plástico que comprende tereftalato de polietileno y/o ácido poliláctico. La invención también se refiere a un método de producción de monómeros y/u oligómeros a partir de un producto de plástico que comprende al menos un poliéster, en particular, tereftalato de polietileno y/o ácido poliláctico, que comprende someter el producto de plástico tanto a una etapa de amorfización como a una etapa de despolimerización.

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.
