“…Currently, there is a global resource scarcity problem, compounded by limited domestic cotton production in China. Hence, the textile industry is urgently looking for biodegradable material and alternatives to scarce resources [1][2][3][4]. Since the widespread cultivation and planting of Arundo donax L. in China, it has become a crucial ecological barrier for environmental protection in the Yellow River Basin and Northwest Desert.…”

In this study, Arundo donax Linnaeus was utilized as the biomass and a TH/DS (Tetra-n-butylammonium hydroxide/Dimethyl sulfoxide, C16H37NO/C2H6OS) system was employed to dissolve biomass cellulose. The optimal process for the preparation of Arundo donax L. biomass regenerated cellulose fiber was determined through process optimization. The physical properties and antimicrobial performance of the resulting products were analyzed. The results demonstrated that the physical indicators of biomass regenerated cellulose fiber, prepared from Arundo donax L. cellulose, met the requirements of the standard for Viscose Filament (Dry breaking strength ≥ 1.65 CN/dtex, Elongation at dry breaking 15.5–26.0%, and Dry elongation CV value ≤ 10.0%). Additionally, excellent antimicrobial properties were exhibited by the biomass regenerated cellulose fiber developed in this study, with antibacterial rates against Staphylococcus aureus and other three strain indexes meeting the Viscose Filament standards. Furthermore, high antiviral activity of 99.99% against H1N1 and H3N2 strains of influenza A virus was observed in the experimental samples, indicating a remarkable antiviral effect. Valuable references for the comprehensive utilization of Arundo donax L. biomass resources are provided by this research.

Green composites for 3D printing have gained significant attention due to the potential of incorporating natural fillers to reduce costs and enhance performance while maintaining environmental benefits. The use of agricultural by‐products, such as horse gram (Hg), not only promotes waste utilization but also seeks to improve the mechanical properties of biopolymers like PLA. In this study, Hg powder was utilized as a natural filler to enhance the mechanical properties of PLA‐based composites. The composites were fabricated with 1%, 2%, 3%, and 4% Hg powder filler content, and the filament was processed through a single screw extruder machine. Their mechanical properties were systematically evaluated to determine the optimal filler ratio. The results indicate that the incorporation of 1% Hg filler into PLA provided superior mechanical performance compared to Neat PLA. Specifically, tensile strength increased by 11.19%, flexural strength improved by 5.32%, and compression strength increased by 5.94%. In contrast, composites with 2% and 3% Hg filler showed a reduction in these mechanical properties, highlighting that the 1% Hg/PLA composite achieves the best balance between strength and filler content. The findings suggest that the 1% Hg/PLA composite offers an optimized combination of tensile, flexural, and compression properties, making it a strong candidate for environmentally sustainable engineering applications such as lightweight structural components, automotive interior parts, and consumer product casings.Highlights One percent Hg filler improved tensile, flexural strength, and hardness through uniform dispersion. Higher filler content (3%–4%) led to agglomeration, reducing composite performance. XRD and SEM analyses revealed reduced PLA crystallinity and structural defects at higher filler levels.

The recycling of materials is in line with the policy of a closed-loop economy and is currently an option for managing waste in order to reuse it to create new products. To this end, 3D printing is being used to produce materials not only from pure polymers but also from their composites. Further development in this field seems interesting and necessary, and the use of recycled materials will help to reduce waste and energy consumption. This article deals with the use of degradable waste materials for the production of insulating materials by 3D printing. For the study, samples with different numbers of layers (one and five), composite thickness (20, 40, 60, 80, and 100 mm) and composition (including colored resins that were transparent, black, gray, and metallized, as well as resins that were colored gray using soybean oil and gray using natural fibers) were made. The role of natural fillers was played by glycerin and biomass ash with a weight ratio of 5%. The finished materials were tested, and the values of the coefficient of thermal resistance and heat transfer were determined. The best thermal properties among the tested materials were distinguished by a five-layer sample made of soybean-oil-based resin with a thickness of 100 mm. This sample’s heat transfer coefficient was: 0.16 W/m2K. As a material for thermal insulation in 3D printing technology, biodegradable components have great potential.
