Abstract: A method for preparing a binder composition containing water, plant fibers and mineral fillers, wherein the method comprises: preparing a suspension of plant fibers and mineral fillers in water, the weight ratio between the plant fibers and the mineral fillers being comprised between 99/1 and 2/98, refining this suspension, and obtaining a binder composition wherein the refined fibers have a mean size of between 10 and 700 ?m, and wherein the refined fibers, at least partially, embed the refined mineral fillers, wherein refining is carried out in the absence of any grinding medium made of ceramic or metal.

Abstract: The present invention relates to a process for improved dewatering and retention in the production of paper, where an anionic retention agent based on starches, cellulose derivatives or guar gums having no cationic groups and an acidic solution of an aluminum compound are added to the stock containing lignocellulose-containing fibres and optionally fillers. The pH of the stock prior to the addition of the aluminium compound should be at least about 6 to obtain the desired cationic aluminium hydroxide complexes in the stock. The present invention is cost effective and insensitive to the content of calcium in the white water.

Abstract: A process for improved dewatering and retention in the manufacture of paper, where a retention agent containing anionic groups and being based on a polysaccharide or being an acrylamide-based polymer and an alkaline solution of an aluminate are added to the stock containing lignocellulose-containing fibres and optionally fillers. The pH of the stock prior to the addition of the aluminate should be below about 7 to obtain the desired cationic aluminum hydroxide complexes in the stock. The present process is cost effective and insensitive to the content of calcium in the white water.
