Abstract: There has been a recent surge of interest in biobased foams for applications ranging from building sustainability (insulation) to biomedicine, pharmaceutics, and electronics (scaffolds), with nanocellulose-based foams being particularly promising due to their porous and low-density structure. This study compares the production energy, structure, and properties of foams made from TEMPO-oxidized lignocellulose nanofibers (F$_{TOLCNF}$) derived from unbleached wood pulp, and TEMPO-oxidized cellulose nanofibers (F$_{TOLCNF}$) from bleached cellulose pulp. Additionally, the incorporation of tannic acid (TA) as a biobased additive is explored for its ability to enhance the mechanical strength of F$_{TOLCNF}$, contributing to improved performance. This builds upon the inherent advantages of F$_{TOLCNF}$, which not only demonstrate superior structural integrity and load-bearing capacity (specific Young’s modulus of 37.4 J g$^{–1}$, compared to 16.4 J g$^{–1}$ for TOLCNF) but also exhibit a higher yield during production due to the minimal processing required for unbleached pulp. Furthermore, F$_{TOLCNF}$ production requires about 18% less cumulative energy than F$_{TOLCNF}$ (27 vs 33 MJ kg$^{–1}$), largely owing to the energy-efficient preparation of TOLCNF from unbleached wood pulp. F$_{TOLCNF}$ also have a significantly lower cumulative energy demand (CED) compared to fossil-based alternatives like expanded polystyrene (EPS) and polyurethane (PU), highlighting their reduced environmental impact. Despite their lightweight nature, F$_{TOLCNF}$ exhibit competitive compressive strength, making them viable candidates for eco-friendly applications across various industries. Overall, this study demonstrates that F$_{TOLCNF}$ are an attractive alternative to other bio- and fossil-based foams, offering a balance of energy efficiency, higher yield, mechanical performance, and sustainability.
