Abstract
La presente invención se relaciona generalmente con el campo de la degradación de poliuretano (PU), por ejemplo, capas de PU en empaques de múltiples capas. Por ejemplo, la presente invención se relaciona con un método para degradar poliuretano (PU) que comprende la etapa de someter el PU a un cóctel de enzimas que comprende al menos una lipasa y al menos una cutinasa. El PU puede ser una capa a base de PU en una estructura de empaquetado de múltiples capas comprendida en un empaque. Notablemente, la materia de la presente invención permite la degradación selectiva eficiente de las capas que contienen PU en materiales de empaque de múltiples capas.
