Summary The valorization of sawdust (SW) biomass by‐product, to extract cellulose through alkali and bleaching processes, including side‐streams to recover hemicellulose and lignin, is performed with the intention of evaluating differences with a proposed green method (GM). The study is developed with the intention of having a process at laboratory scale without leading to the complicated nanoscale processing. This study contemplates a process with scalable characteristics for the future, which contributes to wood processing waste around the world. Particularly, agroindustrial wastes from Durango (SWT1) and Hidalgo (SWT2), local communities of Mexico, were studied. SWT1 and SWT2 samples were processed with ethanol, sodium hydroxide followed by bleaching with sodium chlorite/acetic acid to remove, extractives (E), hemicellulose (H) and lignin (L), respectively. Selected‐SWT2 was processed through a proposed GM using hydrogen peroxide/sodium hydroxide. On the basis of results including Fourier transform infrared spectroscopy, thermogravimetric/differential analysis (TGA/DTG), X‐ray diffraction (XRD), dynamic light scattering, high heating value, scanning electron microscopy techniques and chemical composition, GM was capable of producing a biomass rich in α‐cellulose (58.0%: SWT2‐C), whereas processed SWT1 and SWT2 through conventional method led to a more percentage of H, β‐ and γ‐C mixtures than α‐polymorphous; 41.0% and 51.0%, respectively. This new method could impact of an important manner to the development of biodegradable thermoplastics. The approximation, from deconvolution of TGA/DTA, led to determine adequately the composition of hemicellulose (SWT1‐C: 51.0%, SWT2‐C: 36.0–0.00%), lignin (SWT1‐C: 17.0%, SWT2‐C: 20.0%) and cellulose (SWT1‐C: 32.0%, SWT2‐C: 44.0%). XRD analysis also indicated that samples contain the following percentage of polymorphous cellulose compounds: SWT1‐C (Type II: 71.3%), SWT2‐C (Type I α: 44.6% and II: 41.4%) and SWT2‐C‐GM (Type II: 38.8%), which confirms that the combination of the type of biomass and the applied pretreatment plays a fundamental role for final applications; in this case, it can be appropriate for elastomers and thermoplastic uses. As a final point, the cellulose composition and thermal stability of both sources is comparable with the commonly used raw material for commercial products.

The expanding field of lignin-containing nanocellulose offers a sustainable alternative to fossil-based substances in applications such as packaging, coatings, and composites. This has underscored the importance to explore the impact of raw materials due to the complexities of lignin structures and different raw fiber characteristics, which plays a significant role in determining the properties of the resultant lignin-rich cellulose materials. This study presents a detailed investigation and comparison on the production and structure-property relationships of lignin-containing microfibrillated cellulose (LMFC) fibers prepared from unbleached softwood and hardwood kraft pulps. The microfibrillation process was analyzed for both softwood and hardwood pulps, comparing the results across various stages of fibrillation. Distinguishing features of lignin structures in softwood and hardwood pulps were identified through Py-GC/MS analysis. Additionally, Digital Image Correlation was employed to investigate the varying failure patterns in LMFC films derived from different wood species. Softwood-derived LMFC films demonstrate less strain-concentrated regions and strain variation, attributed to the formation of more physical crosslinking joints by the elongated fibers. Consequently, softwood-origin LMFC films displayed superior load-sharing and enhanced tensile strength (287 MPa) compared to those derived from hardwood. Additionally, the denser lignin structures in unbleached softwood pulp further boosted the stiffness of resultant softwood-derived films. Upon recycling, LMFC films exhibited superior recovery of mechanical properties following drying, suggesting their significant potential for widespread commercial use.
