Abstract

L'invention concerne un procédé de recyclage de produits de papier enduits et/ou revêtus de polymères, selon lequel les produits de papier enduits et/ou revêtus de polymères sont placés dans une suspension aqueuse de vieux papier. Cette suspension de vieux papier a) est battue en présence d'au moins une hydrolase, b) est battue en milieu alcalin, et/ou c) est traitée dans un procédé de désencrage en milieu alcalin, les polymères étant ensuite séparés de la suspension de vieux papier, les polymères étant des polymères biodégradables.
