“…Whether by the action of the steam explosion or by the fine grinding process, the parenchyma cells were easier to separate into smaller filaments compared with the fibers, which was beneficial to the pore-filling of the tableware during water filtration. Additionally, during hydrothermal pressing, the starch granules and modified starch granules in the original lumen of the parenchyma cells formed a starch film through hydration. , This can block pores and restrict the entry of water. During the densification stage of pressing, starch flows again under high pressure and temperature, combining with the fine fibrils.…”

Disposable bamboo fiber tableware is a novel type of product that utilizes sustainable, high-performance bamboo fiber to minimize plastic pollution. In this study, we developed a high-utility bamboo fiber tableware product by employing a novel hybrid fiber-membrane strategy: We used a combination of steam explosion technology and mechanical refining to achieve the “up-down” separation of bamboo. During the molding process, slender bamboo fibers mixed with starch were interwoven into a strong three-dimensional network structure, which resulted in the abundant formation of physical interwinding, fiber bridging, and hydrogen bonding. The above structural features conferred excellent strength, water resistance, oil resistance, better high- and low-temperature resistance, a low content of dissolved substances, and the capacity for rapid degradation when compared with plastic and polylactic acid tableware. We conducted a product life cycle evaluation and found that replacing 20% of plastic tableware products with the bamboo fiber tableware product developed herein would be equal to reducing carbon emissions equivalent to 300,000 cars in a small city.

“…As LFVC samples tended to have larger cell cavities and intercellular spaces, the resin was more likely to penetrate into the pores and form spiky structures on transverse conduits. [ 49 ] The density increase was more significant in the LFVC samples, whereas there was little difference in density between the MLTB samples. The density gap between the OB samples was narrowed according to the degree of resin penetration in single‐layer TB and MLTB samples.…”

Transparent bamboo (TB) is a new type of biomass and light transmitting material with potential to serve as substitute for transparent wood. However, the potential of the bamboo structure in preparing transparent composites is underexplored. Inspired by the functional gradient structure of bamboo, a simple and efficient two‐step strategy to prepare TB with different transmittance levels, fiber textures, and colors is used. The performance of single‐ and multilayer TB with various fiber volume contents prepared using different lamination methods is evaluated. It is found that the optical and mechanical properties of TB differ with the fiber volume content and the lamination method used. TB composed of veneers with low fiber volume shows the highest light transmittance (44.6%), whereas TB composed of veneers with high fiber volume has the highest tensile strength (45.7 MPa). In terms of water resistance, cross lamination inhibits expansion in width (water absorption rate, 16.37–21.26%) and thickness (thickness swelling rate, 10.22–21.74%). The lamination structure and fiber volume content in the preparation of TB should be selected according to the specific application scenarios. The graded utilization of bamboo veneer with a fiber gradient can effectively realize the rational allocation of bamboo resources and promote sustainable development.

“…The chemical composition of other bamboo species in the current study was compared in Table 5. The table showed that the cellulose content (49.26 wt%) of 3year-old O. abyssinica was higher than that of other bamboo species such as Dendrocalamus brandisii (47.24 wt%) [69], Bambusa blumeana (40.3-45.1 wt%) [70], Bambusa tuldoides (35.2 wt%) [71,38], Gigantochloa levis (33.8 wt%) [71], Passiflora edulis (44.64 wt%) [39], and Daphniphyllum oldhami (47.1 wt%] [66]. This showed that O. abyssinica has a great potential for pulp yield and papermaking properties than the mentioned bamboo species.…”

This study examined the chemical composition, fiber morphology, and physical properties of Oxytenanthera abyssinica culm to assess its pulping potential. Technical Association of the Pulp and Paper Industry (TAPPI) and Franklin’s methods have been used for experiments. The statistical analysis showed that the chemical composition of O. abyssinica is influenced by the age of the plant. The amount of cellulose in the culm increases with age, while hand extractive content decreases with age. The average chemical content of the three years aged O. abyssinica was 49.26 ± 0.13 wt%, 21.31 ± 0.15 wt%, and 20.63 ± 0.12 wt% for cellulose, hemicellulose, and lignin contents, respectively. A significant difference exists between 1, 2, and 3-year aged plants ( P < 0.05 ) in cellulose, lignin, ash, and extractive content. The position of the culm also affects the fiber morphology of O. abyssinica. The fiber’s length, diameter, cell wall thickness, and lumen diameter increase from top to bottom, whereas the flexibility and slenderness ratio decrease. The average fiber morphology of O. abyssinica was flexibility ratio ( 0.72 ± 0.10 ), Runkel ratio ( 0.35 ± 0.10 ), slenderness ratio ( 109.98 ± 0.21 ), lumen diameter ( 15.63 ± 0.03 μm), cell wall thickness ( 2.74 ± 0.03 μm), fiber length ( 2.40 ± 0.10 mm), and fiber diameter ( 21.83 ± 0.09 μm). The above data showed that the mean value of the fiber length of the plant is greater than 1.5 mm, the Runkel ratio was less than 1, and the slenderness ratio was greater than 70 standard values. The result also showed that the average bulk density and the moisture content were 660 kg/m3 and 9.6%, respectively. Although O. abyssinica is widely grown in the study area, no comprehensive studies have been carried out on fiber morphology, chemical composition, and physical properties based on age and height. Thus, this research was carried out to study the plant’s fiber characteristics to assess its suitability for pulp and paper production. Based on the above data, the 3-year aged bottom part of O. abyssinica is recommended for more yield pulp and high-quality paper production than the first and second-year aged plant.
