![]() In a circular economy and strict legislative policies, it is essential to keep byproduct materials in circulation through restorative and regenerative methods to maintain their highest value for a long time 1, 2. Thus, sustainable development regarding the environment and natural resources has become an increasingly imperative issue globally. It is unsustainable for the planet to continue to consume its natural resources at the current rate, and therefore it is vital to the future of our planet and species to seek ways to conserve natural resources. As a result, the current work offers a sustainable approach to manage PMS for use in paper coatings as a high-value-added material.Īs the global economy grows, so does the rise in consumption and therefore the burden on natural resources. Notably, the lightness was improved, which also indicates increasing color gamut volume in printing applications. Optical analysis showed slight decrease in brightness and gloss, as was expected. The marginal increase in permeability coefficient and surface roughness, 54% and 10%, respectively, suggests improving color reproduction and preventing color density losses. Results indicated that the obtained CNF PMS in paper coating shows 52% decrease in porosity, presenting significant improvement in the coating microstructure. The effect of CNF PMS additive amounts at two coating layers on microstructure and surface properties of coatings such as porosity, air permeability surface roughness and optical properties such as brightness, gloss and CIE L*a*b* is studied, which they can also provide insight for the eventual print performance. ![]() The purpose of present study is to provide a sustainable approach to PMS utilization as a paper coating additive in the cellulose nanofibrils (CNF PMS) form via simply scalable wire-wound rod coating method. PMS contains significant amounts of cellulose that can be extracted as a raw material. Yet, the shift to using paper mill sludge (PMS) as a source for CNF underscores the significance of reusing and recycling industrial byproducts. Traditionally, cellulose nanofiber (CNF) production has primarily relied on virgin cellulose sources.
