Abstract

La présente invention concerne un procédé de recyclage d'un matériau isolant sous forme de matelas ou de feutre de laine minérale renfermant des fibres minérales qui représentent de 80 à 99% du poids du matériau isolant et un liant comprenant au moins une résine thermodurcie, ledit procédé comprenant une étape consistant à mettre ledit matériau isolant en contact avec au moins une amine sous forme liquide ou gazeuse, pendant une durée suffisante pour décomposer ledit liant. Elle a également pour objet l'utilisation d'une amine pour décomposer le liant contenu dans un matériau isolant sous forme de matelas ou de feutre renfermant des fibres minérales qui représentent de 80 à 99% du poids du matériau isolant et un liant comprenant au moins une résine thermodurcie.
