“…When the concentration of alkali is raised, however, the O-H stretching and H-bonded broad absorption band in the region is reduced. These are due to a decrease in the functional group of phenolic or aliphatic hydroxyl in the fiber due to reaction with sodium hydroxide that promotes free hydroxyl that caused the addition of extra peak in free hydroxyl bond structure [64]. The elimination of hemicelluloses and lignin could be linked to the reduction in these vibrational bands of the IR spectrum of alkali-treated fibers [37].…”

The mechanical properties of single Yushania alpina bamboo fibers have not been explored. This is a serious limitation on their application. The main purpose of this work is to fill up information gaps to prepare for the growing usage of Ethiopian bamboo in a variety of applications. This study looks at the characterization and optimization of Y.alpina bamboo fiber properties extracted both chemically and mechanically. Using response surface methodology (RSM) the mechanical properties were optimized and linear, quadratic and interaction of independent variables were determined. Samples of length 25–30 cm were harvested at various ages from the middle of the stem which was then soaked in different NaOH concentrations weight by volume for different times. Using a rolling machine that has three rollers, the fiber is mechanically extracted. The optimal mechanical properties were observed at plant age of 1.8 years, alkali concentration of 10%, and a soaking duration of 2.0 days. The model is significant (P ≤ 0.005) with a 95% confidence level for predicted values that were closer to the measured values, indicating that the model's fit to the measured properties was strong at the optimized values. The optimized points of age and soaking duration ware subjected to chemical, thermal and morphological analysis for each corresponding NaOH Concentration (6, 12, and 18%) levels. Scanning electron microscopy (SEM) was employed to examine the microstructure of the fibers and discovered that the 18% NaOH treated fiber resulted in more wrinkles in the surface of bamboo fibers when compared with the 6 and 12%NaOH Bamboo fiber. Using thermogravimetric analysis (TGA) and differential thermal gravimetric (DTG), the study investigated weight loss increased as alkali concentration increased but the scenario functioned for proper concentration.

“…The heat resistance calculated to the composite with 20 wt/wt% decreased considerably due to the excess of fiber loading, which presented a lower heat resistance. Therefore, the improvement in the composites' thermal stability can occur due to a better adhesion promoted by the roughness of the macadamia nutshell's surface, improving the mechanical properties 10,29 . Hidalgo‐Salazar, Muñoz, and Mina 60 verified an increase in LDPE‐Al's thermal stability with fiber, which was attributed to the formation of spherulite nucleation points, caused by an increase in crystallinity.…”

Macadamia nutshell residues are generated in large quantities, around 70%-77% for each ton produced, and it is a waste material with high technoeconomic potential. This work purpose a sustainable alternative to valorize macadamia nutshell residues (MN) as reinforcing in low-density polyethylene (LDPE) composites through melt mixing, using different fiber contents (0, 5, 10, and 20 wt%), and investigate the influence of fibers (residues) in composites by mechanical tests and thermal analysis. The fibers addition has significantly increased the composites' stiffness compared with neat LDPE, causing a reduction of toughness and resilience, leading to lower impact energy absorption. The LPDE/MN20% composite obtained the best tensile and flexural mechanical performance, resulting in a maximum modulus, which implies an increase of 36.9% and 77.6% compared with the neat LDPE. The addition of macadamia fibers on the composites acted as nucleation points of spherulites, which promoted an increase in the crystallization degree. Consequently, better performance of mechanical properties was observed in the green composites. Thus, the macadamia nutshell residues present a promising future as filler in LDPE for enhancing composites' thermal and mechanical properties.

Still, there are common steps, such as, drying, extraction of the components, shelling, and separation process, giving the nut kernels and dry nutshell. 2 The agroindustrial crop's valorization is interesting for synthetic chemistry, perfumery, cosmetics, biomedicine, and energy industries.
