“…However, the research regarding the production of fine papers still needs to explore the CMF effects in conditions similar to those of the papermaking industry, namely by considering the complex interactions between cellulosic pulps, CMF, mineral fillers, and the wide range of additives commonly used to produce these paper grades. Some studies have already addressed the theme, with different types of nanocellulose, fillers or addition strategies (Ankerfors et al, 2014;Diab et al, 2015;He, Yang, Cho, Yong, & Jong, 2017;Hii, Gregersen, Chinga-Carrasco, & Eriksen, 2012;Lourenço et al, 2017;Lourenço, Godinho, Gamelas, Sarmento, & Ferreira, 2019). Also, several works have reported the useful interactions between CMF and mineral fillers Tenhunen et al, 2018).…”

Nanocelluloses have been increasingly used in composites since their reduced size, high aspect ratio and stiffness confer great strength to the materials. In papermaking, it has been proved that harsh and expensive chemical pre-treatments to generate nanofibrils, such as TEMPO-mediated oxidation, are not the most favourable and therefore the use of cellulose microfibrils (CMF) have gained extra attention, especially those produced with the aid of enzymatic hydrolysis. In the present work, strategies to improve filler flocculation and the papermaking properties, by using enzymatic CMF, are provided. The CMF degree of polymerization was found to be directly related to precipitated calcium carbonate flocculation, leading to higher retentions in the fibre matrix. Besides, the paper dry and wet strengths were much improved, allowing in return the production of high-filler loaded handsheets with reduced requirements for common paper additives.

“…Any additional energy input beyond this limit will represent an energy loss in the overall energy balance associated with MFC manufacturing. In agreement with this logic, He et al (2017) concluded that MNFC production should be focused on tailoring the properties of the fibrillated fibers to be incorporated into a specific application, i.e., achieving an optimal degree of fibrillation for a given application, rather than trying to retrofit MNFC, whose dimensions are completely nanoscale, to possible applications.…”

“…This can be seen with the use of filler in printing and writing grades. Fillers are significantly cheaper than fiber so companies use as much filler as they possibly can without negatively impacting the paper properties (He et al 2017). This fulfills the customer's expectation while keeping the cost as low as possible, which translates into a higher profit margin.…”

“…The degree of fibrillation influences the dewatering capacity of pulp suspensions and the solid content of the paper after wet pressing. He et al (2017) described an increase in the drainage time as a function of the degree of fibrillation of CNFs, which was accompanied by an overall reduction in the degree of polymerization, zeta potential, and degree of crystallinity. As the fibrillation of fibers progresses, particles are more easily incorporated into the fiber web.…”

Based on publications related to the use of micro-and nanofibrillated cellulose (MNFC) in papermaking applications, three sets of parameters (intrinsic and extrinsic variables, furnish composition, and degree of dispersion) were proposed. This holistic approach intends to facilitate understanding and manipulation of the main factors describing the colloidal behavior in systems comprising of MNFC, pulp fibers, and additives, which directly impact paper product performance. A preliminary techno-economic assessment showed that cost reductions driven by the addition of MNFC in paper furnishes could be as high as USD 149 per ton of fiber (up to 20% fiber reduction without adverse effects on paper's strength) depending on the cost of papermaking fibers. It was also determined that better performance in terms of strength development associated with a higher degree of MNFC fibrillation offset its high manufacturing cost. However, there is a limit from which additional fibrillation does not seem to contribute to further strength gains that can justify the increasing production cost. Further research is needed regarding raw materials, degree of fibrillation, and combination with polyelectrolytes to further explore the potential of MNFC for the reduction of weight of paper products.

“…Micro-and nanofibrillated (MNFC) has emerged as a promising candidate to generate either high-value applications or low-cost alternatives. Thus far, available reports have been focused on the improvement in tensile strength by addition of MNFC in paper furnishes (Eriksen et al 2008;Taipale et al 2010;He et al 2017). This might be mainly beneficial for poor quality furnishes composed of recycled fibers, where strength properties of such fibers can be insufficient to meet specifications of a paper grade.…”
