Abstract

L'invention concerne un procédé de fabrication de pâte destinée à la fabrication de produits en papier au moyen d'un rayonnement micro-ondes afin de prétraiter la source de pâte avant tout traitement ultérieur. La mise en oeuvre de ce procédé permet d'économiser sensiblement de l'énergie tout en diminuant les répercussions sur l'environnement et en améliorant les propriétés du papier.
