  • ENZYMATIC RECYCLING OF POLYURETHANES BY A COMBINATION OF CUTINASES AND ESTERASES
    Publication number: 20240084094
    Abstract: The present invention relates generally to the field of degrading polyurethane (PU), for example PU layers in multi-layer packaging. For example, the present invention relates to a method of degrading polyurethane (PU) comprising the step of subjecting the PU to an enzyme cocktail comprising at least one esterase and at least one cutinase. The PU may be a PU-based layer in a multilayer packaging structure comprised in a packaging. Remarkably, the subject matter of the present invention allows the efficient selective degradation of PU containing layers in multi-layer packaging materials.
    Type: Application

  • ENZYMATIC RECYCLING OF POLYURETHANES BY CUTINASES
    Publication number: 20230391978
    Abstract: The present invention relates generally to the field of degrading polyurethane (PU), for example PU layers in multi-layer packaging. For example, the present invention relates to a method of degrading polyurethane (PU) in packaging material comprising the step of subjecting the packaging material comprising the PU to at least one cutinase. The PU may be a PU-based layer in a multilayer packaging structure comprised in a packaging. Remarkably, the subject matter of the present invention allows the selective degradation of PU containing layers in multi-layer packaging materials.
