Summary: A waste-valorization approach was developed to transform recalcitrant hydrolysis lignin into multifunctional bio-based products, including nanocomposite films with tailored properties. The influence of lignin type on particle size and ecotoxicity, as well as the carbon footprint of the entire process, were evaluated to consider an integration to industrial scale. This work provides a proof of concept for utilizing lignin-rich side streams from bioethanol production for functional nanomaterials and renewable composites.

Summary: A new method for the synthesis of nanofibrillar cellulose/polystyrene composite is proposed, which involves ultrasonic treatment of styrene emulsion in cellulose-water solution. This method eliminates the need for additional heating and significantly reduces the synthesis time compared to previous methods. Comprehensive analysis indicates that the mechanical, physical, and biodegradable properties of the composite obtained by the ultrasonic method are comparable to those obtained by the conventional thermal method.

Summary: Nanocellulose (NC) has garnered significant attention as a green packaging material for its ability to protect food from pathogens and biodegrade after disposal. This review explores various methods of preparing NC-based films, including layer by layer assembly, electrospinning, coating, extrusion, casting, vacuum filtration, and immersion. The article summarizes the interaction between microorganisms and NC, focusing on the impact of NC on microbial adhesion and the influence of microorganisms on the degradation of NC-based films. The challenges of NC in packaging, such as hydrophobicity, antibacterial properties, and industrialization are discussed, along with future perspectives for NC-based films as packaging materials.

Summary: This study evaluated the degradability of polylactic acid (PLA) and starch-based bioplastics (SBB) under industrial conditions. The results showed that the disintegration of these bioplastics did not meet the standard requirements, with residues found in compost. Phytotoxicity tests indicated that PLA elutriate had the lowest Germination Index, while SBB had a potential negative effect on soil fauna. Further investigation is needed to understand the fate of these materials in industrial conditions and assess the effects of residues in compost.

Summary: This study investigates the isolation of cellulose nanofibrils (CNF) from sugarcane bagasse and the production of CNF-based aerogels using oxidation/fibrillation processes. The resulting TMI/NR composite aerogels exhibit excellent adsorption performance and are able to effectively remove pollutants from water.

Summary: This study found that microfibrillated cellulose (MFC) enhances the biodegradation of PLA while cellulose nanocrystals (CNCs) inhibit it. However, a synergistic effect was observed when both fibers were present, accelerating the biodegradation process of the hierarchical PLA biocomposites.

Summary: This study demonstrated the production of bio-based films/nanopapers using cellulose nanofibrils (CNFs) from banana tree pseudostem (BTPT) wastes and Eucalyptus kraft cellulose (EKC), showing attractive mechanical properties and biodegradability. Increasing the number of fibrillation cycles resulted in more transparent films with significant reduction in water absorption.

Summary: This study investigated the impact of cellulose nanocrystal (NCC) content on the biodegradation kinetics of PLA-based multiscale cellulosic biocomposites (PLAMCBs). Thermo-oxidation treatment at 70°C for 160 hours was found to enhance the biodegradability of PLA. The addition of cellulosic fibrous reinforcements and the partial substitution of micro cellulose (MFC) with cellulose nanocrystals (NCCs) also increased the biodegradability of the biocomposite by facilitating hydrolysis.

Summary: The study demonstrates the beneficial effects of premixing highly loaded poly (butylene succinate) (PBS) / nanofibrillated cellulose (NFC) nanocomposites under solution conditions and using them as a masterbatch for melt blending. The masterbatch process significantly reduces solvent usage and improves NFC dispersion in the polymer matrix. Samples processed with the masterbatch show enhanced overall mechanical properties compared to conventional solvent casting, indicating a high potential for high-performance materials.

Summary: The study investigated the effects of starch and 2-hydroxyethyl cellulose additives on the structure, properties, ecotoxicity, and degradation of fully aliphatic polyester-ether polyurethane foams. The addition of starch and HEC resulted in tougher foam with slightly increased open-cell content but coarser cellular structure, larger cell sizes, and reduced water absorption. Biodegradation by bacteria was similar for all tested foams, while fungus biodegradation was more efficient in starch and HEC-modified foams, which also exhibited higher ecotoxicity for higher organisms.

Summary: Phosphorylated cellulose nanocrystals (P-CNCs) are derivatives of cellulose nanocrystals (CNCs) that have garnered attention in various industries. A new eco-efficient process combining pre-phosphorylation with mechanical fibrillation was developed for the production of P-CNCs. This process not only improved the quality of P-CNCs, but also showed better environmental and economic performance compared to existing production processes.
