Beschreibung
Zusammenfassung:	A substantially dry composite material comprising a nanofibrillated polysaccharide and two or more additives, wherein the composite nanofibrillated polysaccharide is a microfibrillated cellulose and wherein the additives are lime milk and carbon dioxide, wherein the additives are allowed to react with each other and forming a precipitated calcium carbonate on the nanofibrillated polysaccharide, thereby forming a composite product comprising precipitated calcium carbonate and nanofibrillated polysaccharide.
