Disclosed is a method for preparing paper pulp from cornstalks comprising the steps of cooking, washing, screening, thickening, bleaching, beating and drying performed under moderate conditions which have little noxious effects on the environment. By using cornstalks as raw materials for paper pulp, it becomes possible to replace import of wood raw materials, to save foreign currency, to increase rural income, and to make high quality paper.

L'invention porte sur un procédé de préparation de la pâte à papier et, plus précisément, sur un procédé de préparation de la pâte à papier à partir de tiges de maïs, qui consiste notamment à cuire à haute pression, à battre, à disperser et à sécher d'une manière modérée peu nuisible à l'environnement. L'utilisation de tiges de maïs comme matière première pour la pâte à papier permet de remplacer l'importation du bois brut, d'économiser des devises, d'accroître les revenus du monde rural et de réaliser un papier de haute qualité semblable à celle du papier coréen.
