Special Issue Information

Dear Colleagues,

Since the 1990s, the term nanocellulose has been included in the scientific literature. Due to its physical, chemical, mechanical, and biocompatibility characteristics, it represents an innovative and promising material.

Multiple potential applications were proposed by the early 2000s onwards. Most of the nanocellulose uses were identified in the paper and packaging industries; nonetheless, biomedical, cosmetic, aerospace, environmental, agricultural, automotive, and energy applications have also been explored. The inherent high surface area of nanocellulose particles is an important feature that brings numerous and fascinating possibilities.

The evolution from lab-scale to pilot plants and industries is a consequence of innovation in the processes that face financial, technical, and environmental challenges. Propelling nanocellulose industries to the next generation of products and services deeply depends on the process by fostering new industrial views and developing markets for innovative products.

The versatility displayed by nanocellulose variants is remarkable. New approaches, such as tissue engineering or the creation of matrices for multiple purposes, including wastewater treatment, air quality, biosensoring, cosmeceuticals, delivery systems, and wound healing, are only a few of the bioengineering applications for this material. On the other hand, the search for innovation through the replacement of existing goods and services with improved nanocellulose-based ones faces big challenges for the widespread use of nanocellulose materials.

In this Special Issue, we intend to foster discussion and revise the current solutions toward the incorporation of nanocellulose types in diverse markets. The focus of this Special Issue is the innovation of processes, which embraces multiple dimensions such as intellectual property, national and international regulation frameworks, market and consumer preferences, environmental considerations, and toxicological approaches that need to be overcome before nanocellulose is used in day-to day-goods and services.

We welcome articles focused on, but not limited to, the innovation in processes that are engaged in biorefineries or industries implementing zero-emissions policies. We are searching for the processes involved in scientific and engineering advances for the industrial production of nanocellulose. Themes like novel nanocellulose functionalization for specific solutions, novel composites with a commercial focus, industrial experience in processes and products, adaptation to regulatory frameworks affecting innovation and production, and market perception, opportunities, and challenges are welcome in this Special Issue.

The study explores γ-valerolactone (GVL) pulps as a sustainable approach to producing microfibrillated (MFC) and nanofibrillated (NFC) cellulose from sugarcane bagasse, a widely available agro-industrial by-product. Pulp was obtained by acid-catalyzed organosolv delignification with a GVL–water system. MFC was generated through a simple disc refiner, while NFC was produced by TEMPO-mediated oxidation followed by mechanical treatment in a colloidal mill. NFC and MFC produced using the same methodology from a commercial sugarcane totally chlorine-free (TCF) soda–anthraquinone (soda–AQ) pulp served as a reference. Structural and physicochemical characterization involved optical transmittance, turbidity, conductimetry, X-ray diffraction, viscosity, FTIR, carboxyl content, cationic demand, degree of polymerization, and morphology by scanning electron microscopy (SEM). Results demonstrated that xylan and residual lignin contents influenced MFC formation, and the NFC showed properties comparable to those of the commercial pulp with fewer fibrillation passes. The study highlights GVL pulping as a greener, efficient alternative to conventional processes, opening new pathways for producing viscosity-controlled nanocellulose suspensions suitable for advanced applications.
