“…Figure 5 shows the TEM image of CNCs obtained by acid hydrolysis. The TEM results in Figure 5 a,b show that the CNCs produced by acid hydrolysis showed a rod-like structure, which was consistent with the CNCs produced by other sources before [ 34 , 39 , 46 ]. CNCs have slight agglomeration, as is shown from Figure 5 a, due to the presence of intermolecular and intramolecular hydrogen bonds and the high specific surface area of CNCs [ 53 ].…”

“…Because the glycosidic bonds in the amorphous region are preferentially hydrolyzed and broken during the hydrolysis process, the cellulose molecules are rearranged and the crystallinity is higher. The crystallinity index increases with crystallite size due to the reduction in amorphous regions [ 46 , 47 ].…”

“…Figure 4 e,f shows that the surface particles of the D-JC completely disappeared and some small pores appeared, which facilitated the penetration of NaClO 2 , resulting in a pure cellulose B-JC as shown in Figure 4 g,h. Compared with other samples, the diameter of the B-JC was significantly reduced in Figure 4 h, which further indicated the removal of non-fiber components, thereby separating individual fibers [ 46 ]. Figure 4 h shows that the cellulose fiber surface was relatively rough and cracks appeared.…”

Jujube cores are fiber-rich industrial waste. Dewaxing, alkali treatment, bleaching, and sulfuric acid hydrolysis were used to generate cellulose nanocrystals (CNCs) from the jujube cores in this study. The morphological, structural, crystallinity, and thermal properties of the fibers were investigated using FE-SEM, TEM, AFM, FT-IR, XRD, and TGA under various processes. CNCs’ zeta (ζ) potential and water contact angle (WAC) were also investigated. The findings demonstrate that non-fibrous components were effectively removed, and the fiber particles shrunk over time because of many activities. CNCs had a rod-like shape, with a length of 205.7 ± 52.4 nm and a 20.5 aspect ratio. The crystal structure of cellulose Iβ was preserved by the CNCs, and the crystallinity was 72.36%. The temperature of the fibers’ thermal degradation lowered during the operations, although CNCs still had outstanding thermal stability (>200 °C). Aside from the CNCs, the aqueous suspension of CNCs was slightly agglomerated; thus, the zeta (ζ) potential of the CNCs’ suspension was −23.72 ± 1.7 mV, and the powder had high hydrophilicity. This research will be valuable to individuals who want to explore the possibility for CNCs made of jujube cores.

“…The tensile characteristics are one of the most critical parameters used to determine the maximum strain that the bio nanocomposite films may withstand before failing. [ 5 ] The tensile strength and Young's modulus of pristine PVA were 29.5 ± 1.5 MPa and 6.8 GPa, respectively. Simultaneously, the tensile strength of CCNCs loaded with PVA films at 1 and 2 wt% is 43.7 ± 3.2 and 52.5 ± 2.5 MPa, respectively.…”

The agricultural waste dumped onto the land is creating an environmental problem. The conversion of those easily available agro-wastes into value-added nano reinforcement materials for biopolymers is an alternative method of waste utilization and minimization. In the current study, the red banana peduncle (RBP) waste was used as a precursor in the extraction of carboxylated cellulose nanocrystals (CCNCs) by alkalization, acidified chlorination citric acid hydrolysis, as well as the assessment of its reinforcing capability in polyvinyl alcohol. The characterization of the extracted CCNCs is analyzed through electron microscopy, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), and Thermogravimetric analysis (TGA), respectively. The CCNCs exhibit a rod-like shape (235 ± 20 nm length and 17.2 ± 6 nm width) with a high crystallinity of 89.7%, a negative zeta potential (À48 mV), and good thermal resistivity against degradation up to 280 C. Furthermore, the effects of CCNCs integration on the bionanocomposite films' tensile, optical, bio decomposition, and thermal behavior were examined. The bionanocomposite film with improved physical, functional, thermal and bio decomposition characteristics offers the possibility for active packaging applications.

The contemporary world is concerned only with non-biodegradable waste management which needs more sophisticated procedures as compared to biodegradable waste management. Biodegradable waste has the potential to become useful to society through a simple volarization technique. The researchers are behind sustainable nanotechnology pathways which are made possible by using biodegradable waste for the preparation of nanomaterials. This review emphasizes the potentialities of biodegradable waste produced as a viable alternative to create a sustainable economy that benefits all humans. Volarization results in the utilization of biowastes as well as provides safer and hazard-free green methods for the synthesis of nanoparticles. Starting from different sources to the application which includes therapeutics, food industry and water treatment. The review hovers over the pros and cons of biowaste-mediated nanoparticles and concludes with possible advances in the application. In the present scenario, the combination of green synthesis and biowaste can bring about a wide variety of applications in nanotechnology once the hurdles of bulk-scale industrial production are resolved. Given these points, the review is focused on the cost-effective synthesis of metal and metal oxide nanoparticles.
