Zusammenfassung:	Removal of stickies from waste paper and paperboard is obtained with the use of a modified kaolin-based stickies removal composition. The modified kaolin-based stickies removal composition is produced by modifying the kaolin clay, separating the modified kaolin clay from the non-reactive kaolin clay, and then adding a nonionic surfactant to the modified kaolin-based particles. Removal of stickies is improved by the use of this modified kaolin-based stickies removal composition during the recycling of the waste paper and paperboard. Selon l'invention, l'élimination de matières collantes de déchets de papier et de carton est obtenue grâce à l'utilisation d'une composition d'élimination de matières collantes à base de kaolin modifié. La composition d'élimination de matières collantes à base de kaolin modifié est produite en modifiant l'argile de kaolin, en séparant l'argile de kaolin modifiée de l'argile de kaolin non réactive, puis en ajoutant un tensioactif non ionique aux particules à base de kaolin modifié. L'élimination de matières collantes est améliorée en utilisant cette composition d'élimination de matières collantes à base de kaolin modifié pendant le recyclage des déchets de papier et de carton.
