The main goal of this study was to evaluate the production
potential of cellulose nanofibers from two different industrial
residues using a mild pretreatment and ultrafine grinding. The process
is evaluated in terms of yield, energy efficiency and output
quality, and thus, the potential for scaling up is assessed. To study
the effect of the raw material source on the fibrillation process,
measurements ofthe viscosity and microstructure were performed
during the grinding process. The mechanical properties ofthe dried
fiber networks were used as an indirect measurement ofthe degree
of separation. In addition, the morphology was studied using SEMand AFM and the crystallinity with both XRD and Raman spectroscopy.
