Abstract

La présente invention concerne un procédé pour préparer une pulpe minérale en préparant des fibres minérales écologiques en utilisant des ressources en résidus de charbon telles que les résidus de charbon, les cendres de charbon, la poussière de charbon, la pierre ponce, les rebuts de charbon ou les résidus générés dans les installations industrielles autour des mines de charbon et des mines de charbon désaffectées, ainsi que des déchets industriels tels que les résidus de sable de fonderie ou de laitier comme additif, en ajoutant une pulpe et en réalisant une modification chimique ainsi qu'une étape de fabrication du papier et de ramollissement. Les divers types de fibres minérales fournis lors d'une étape intermédiaire pour la préparation sont des matériaux industriels, de construction, d'isolation contre la chaleur, ignifuges, de friction, d'isolation contre le froid et agricoles et ces fibres minérales sont utiles en tant que matériau écologique flexible et doté d'une excellente force de rappel. De plus, la pulpe minérale peut se substituer, comme matériau final, à la pulpe naturelle importée. L'énergie dépensée et les émissions polluantes sont remarquablement réduites grâce au recyclage des ressources en résidus, ce qui contribue ainsi à une croissance verte et permet de participer au développement économique et à la création d'emplois dans les régions minières désertées.
