In our study, the binding properties of fillers were improved by using cellulose nano- (CNF) andmicrofibrils (CMF). Savings in costs, materials and energy are looked for by increasing the fillercontent of the studied paper grade (SC-paper). The objective of this study was to createmechanically stable and durable aggregates that simultaneously enhanced dry and wet strengthproperties, filler retention and dewatering compared to traditional fillers. By developing the bindingPCC-CMF/CNF aggregates, it was possible to increase the filler content of papers from 30% to40% and to reduce variable costs in SC-paper production. The new material combinations alsodeveloped open up possibilities beyond paper applications.
