  • Process of recycling mixed PET plastic articles
    Patent number: 10385183
    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.
    Type: Grant

  • A METHOD FOR DEGRADING A PLASTIC
    Publication number: 20160280881
    Abstract: The present invention relates to a method for degrading a plastic containing non-biodegradable polymers comprising submitting said plastic to at least one enzyme for modifying a polymer of said plastic which has a methane potential less than 5 Nm3/t+/?20%, wherein at least one product resulting from the modification exhibits a methane potential greater than 10 Nm3/t+/?20%.
