Special Issue Information

Nanocellulose (NC), cellulose in nanostructures, has been proved to be one of the most prominent green materials of modern times because of its remarkable features, including recyclability, biocompatibility, low-risk toxicity, and tunable surface properties. Currently, NC-based materials from sourcing, synthesis, and surface modification governed by its structural and physicochemical features, including excellent mechanical properties and biocompatibility, are applied for functional paper, optoelectronics, antibacterial coatings, packaging, mechanically reinforced polymer composites, tissue scaffolds, drug delivery, biosensors, energy storage, catalysis, and environmental remediation. With increasing environmental and ecological concerns due to the use of petroleum-based chemicals and products, the synthesis of sustainable materials from natural resources such as NCs is of great public value. This Special Issue, “New Application of Nanocellulose,” aims to address the recent advances and emerging uses of NCs in the fabrication of nanocomposites (including those based on polymers, metals, metal oxides, and carbon), suitable components to form inks for 3D printing, Pickering emulsifiers (emulsion stabilized by solid particles), effluent treatment (removal of toxic heavy metal ions and organic pollutants), food packaging and biomedical applications (drug delivery, repairing connective tissue and for constructing contact lenses and protective barriers). Finally, the challenges and opportunities of NCs-based emerging materials.

Paper production and recycling result in large amounts of recycled paper sludge (RPS) that is currently being disposed of in very costly and unsustainable practices, raising the importance of developing green solutions for waste management. The use of nanocellulose (NC) as the next generation of materials has gained much attention due to its economic potential. However, there are substantial challenges in NC extraction, detection, and quantification methods. In this study, NC was produced from RPS as a means of converting waste into a resource. The process included a short, 30 min ozonation (21 mg O3/g RPS), which allowed a sufficient delignification and facilitated the following hydrolysis step. Among all tested durations, a 4-h hydrolysis with 64% w/w sulfuric acid resulted in the highest NC production. Fluorescent staining by calcofluor white was used for simple and low-cost detection of NC in-situ. Crude NC showed a significant 63% dye uptake of 0.1 ppm acid red 131 within 30 min. Compared to the standard disposal methods of RPS, its utilization for NC production supports the circular economy concept and significantly contributes to the development of cellulose bio-based nanomaterials for water treatment applications.
