In our study, the binding properties of fillers were improved by using cellulose nano- (CNF) and microfibrils (CMF). Savings in costs, materials and energy are looked for by increasing the filler content of the studied paper grade (SC-paper). The objective of this study was to create mechanically stable and durable aggregates that simultaneously enhanced dry and wet strength properties, filler retention and dewatering compared to traditional fillers. By developing the binding PCC-CMF/CNF aggregates, it was possible to increase the filler content of papers from 30% to 40% and to reduce variable costs in SC-paper production. The new material combinations also open up possibilities beyond paper applications.
