Abstract

Jute fiber used in the production of yarn is traditionally treated with a 2% emulsion of jute batching oil (JBO) to reduce stiffness and improve processability. However, due to the high cost and potential carcinogenic effects of JBO, there is a pressing need for alternative methods. This study investigates the use of a microbial consortium to achieve a cost-effective and eco-friendly reduction of JBO use in yarn production. A total of 51 bacterial strains were isolated from JBO-treated jute fiber at Janata Jute Mills, with 17 strains exhibiting significant growth in 2% JBO. After excluding duplicates, potential pathogens, and strains with endoglucanase activity, a final consortium of nine bacteria was established. The physical properties of jute fiber treated with this consortium alongside varying concentrations of JBO (1% and 2%) were analyzed over different incubation periods. Results indicated that treatment with 1% JBO and the bacterial consortium produced comparable effects on temperature and moisture regain to the control group (2% JBO). Notably, fibers treated with the consortium exhibited enhanced elasticity, showing a 46.6% increase in maximum pressure and 12.2% increase in extension at breakage compared to the control (2% JBO). Additionally, wastage during processing was reduced by 24.1% for breaker card processing in the treated group. Scanning electron microscopy (SEM) revealed a rough surface morphology in the treated fibers, indicative of biofilm formation. This study suggests that employing microbial consortia with reduced JBO concentrations offers a promising alternative for enhancing fiber quality in jute yarn manufacturing while promoting environmentally sustainable practices.

Abstract

Water hyacinth (Eichhornia crassipes) is an abundant aquatic biomass whose utilisation as a reinforcement fibre is limited by high contents of hemicellulose, lignin, waxes, and inorganic deposits. This study evaluates the effect of 10 % NaOH treatment on the structural, chemical, thermal, and mechanical properties of water hyacinth fibres (WHF). Scanning electron microscopy with energy-dispersive spectroscopy (SEM/EDS), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), X-ray fluorescence (XRF), thermogravimetric analysis (TGA/DTG), and single-fibre tensile testing were employed. Alkali treatment induced extensive defibrillation of compact fibre bundles into individual microfibrils (≈2–7 µm), transformation of cellulose I to cellulose II, and a marked increase in crystallinity from approximately 25 % to 71 %. Potassium and chloride contents were reduced by more than 99 %, and the maximum thermal degradation temperature increased from about 337 °C to 367 °C. Tensile strength and Young’s modulus increased from 18.4 ± 3.1 MPa to 58.1 ± 2.9 MPa and from 1.42 ± 0.18 GPa to 4.83 ± 0.23 GPa, respectively. These results demonstrate that NaOH treatment effectively purifies and structurally optimises WHF, significantly enhancing its thermal resistance and mechanical performance for sustainable composite reinforcement applications.

Abstract

The growing demand for sustainable materials and effective waste management has encouraged the development of environmentally friendly composites. Green composites are a promising alternative to conventional materials for environmental preservation. In this study, bacterial cellulose derived from nata de coco was used as a matrix, while haircut waste particles served as a filler. Composites were fabricated via compression molding at 170 °C with filler contents of 0, 15, 25, 35, and 45 wt.%. The synthesized materials were characterized through tensile testing, scanning electron microscopy (SEM), and Fourier transform infrared (FTIR) spectroscopy. Increasing hair-particle content increased the elastic modulus from 44.11 ± 3.02 MPa (A1) to 130.46 ± 4.94 MPa (A2), indicating enhanced stiffness of the composite; however, further increases in filler content slightly reduced the modulus due to possible void formation and weaker interfacial adhesion. In contrast, the tensile strength decreased progressively from 11.54 ± 0.56 MPa (A1) to 5.16 ± 0.52 MPa (A5) with increasing filler content. SEM observations revealed the formation of voids and weaker matrix–filler interactions at higher filler contents, which contributed to the reduction in tensile strength. FTIR spectra showed the presence of O–H, C–H, and C=O functional groups, suggesting possible interactions between bacterial cellulose and hair particles. Overall, a filler content of 15 wt.% provides the best balance between stiffness and structural integrity, demonstrating the potential of hair waste as a sustainable reinforcement in bacterial cellulose-based green composites.

Abstract

This study focuses on the development and characterization of adhesives based on Polyvinyl Alcohol (PVA), Tannic Acid (TA), and Cellulose Nanofibre (CNF). The main objective is to optimize the temperature used in the production process. Phenol-formaldehyde and other synthetic adhesives frequently encounter environmental obstacles, necessitating the search for more ecologically sound alternatives. TA, a naturally occurring polyphenolic molecule, has significant potential as an eco-friendly glue ingredient. This study assesses the impact of temperature fluctuations (30, 45, 60, 75, and 90°C) during the glue manufacturing process on its mechanical characteristics, specifically emphasizing shear stress. Experiments were conducted at a rotational speed of 1500 revolutions per minute (RPM) for 30 minutes. The results indicated that the adhesive performed best at 90°C, achieving a maximum shear stress value of 3.41 MPa. The results demonstrated a significant enhancement in the shear strength of the bioadhesive, exhibiting an approximately sixfold increase as the processing temperature was elevated from 30°C to 90°C. Microstructural analysis reveals that the voids formed during the mixing process decrease at this specific temperature. The results indicate that elevated temperatures lead to a significant reduction in void formation. The FTIR measurement revealed the absorption of hydroxyl groups around 3305 cm⁻¹, suggesting the presence of robust crosslinking. Furthermore, elevated temperatures lead to a significant reduction of free OH- groups within the bioadhesive. The PVA/TA/CNF adhesive possesses extensive potential for application in industries that necessitate adhesives with exceptional strength. The study is anticipated to offer comprehensive understanding of how to improve the manufacturing process of TA-based adhesives, and its impact on the creation of adhesive materials that are more sustainable and environmentally friendly.

Abstract

Extensive and irresponsible use of conventional plastic has brought serious problems to the planet due to its low biodegradability. In order to reduce the risks, packaging materials made from biodegradable materials are extremely needed. This study develops active packaging films using sago starch and bacterial cellulose incorporated with Gunuang Omeh orange peel essential oil. It also evaluated the effect of different drying temperatures on the physicochemical, mechanical, structural, and antimicrobial properties of the resulting films. The solvent casting method was used to prepare sample films with 3 drying temperatures (40, 45, and 50°C). The functional properties and antibacterial activity against E. coli and S. aureus of films with and without essential oil were characterized and analyzed. The results showed that drying temperature significantly influences the performance of the biofilms. Higher tensile strength (2.38 MPa) and lower moisture absorption were found at 45°C dried films. The presence of essential oil slightly increased water solubility and improved antibacterial activity, with inhibition zones ranging from 7.70–15.77 mm against E. coli and 4.83–5.75 mm against S. aureus. In conclusion, sago starch–bacterial cellulose films incorporated with Gunuang Omeh orange essential oil demonstrate a future potential as eco-friendly packaging materials, with drying temperature identified as a critical processing parameter for optimizing functional performance.

Abstract

Hybrid natural-synthetic fiber composites are attractive for automotive acoustic trim only when composition effects are separated from geometric effects and the computational assumptions are fully reproducible. This study presents a transparent screening framework linking normal-incidence acoustic absorption, a literature-informed vibration-damping proxy, specific stiffness, mass and constituent-production environmental metrics. Twelve polypropylene-based formulations were compared at a common thickness of 20 mm; 16, 20 and 24 mm were then evaluated separately in the thickness-sensitivity analysis. Open porosity and flow resistivity were generated by explicit bounded composition-to-property rules and used in the Miki equivalent-fluid model. Environmental inputs were evaluated with 20,000-trial triangular uncertainty propagation, while the multi-criteria ranking used winsorized normalization and 10,000 weight-perturbation scenarios of +/-15%. At 20 mm, broadband absorption averages (500-4000 Hz) occupied a narrow range of 0.612-0.636, demonstrating that acoustic comparisons are sensitive to geometry and that thickness must be controlled when isolating composition effects. Increasing thickness from 16 to 24 mm raised the modeled broadband absorption of representative natural-fiber-rich panels from about 0.55 to 0.69. C25-G10-R5 ranked first under the baseline weights and in 100% of weight-perturbation scenarios; JC30-G10 remained in the top three in 100% of scenarios and C35-rP5 in 79.1%. Median constituent-production greenhouse-gas reductions relative to GF40-PP ranged from approximately 26% to 56% for the non-aramid hybrid candidates, whereas the aramid-containing design was environmentally unfavorable. The reported damping values are screening proxies, not measured loss factors, and the environmental calculation is not a full ISO-compliant comparative LCA. The framework is therefore intended for hypothesis generation and experimental down-selection rather than direct certification of material performance.

Abstract

Modelling of the Transport Behaviour of selected solvents through Epoxy Coated Grey Fabrics had been carried out. The epoxy coated fabrics were formulated by coating the grey states of cotton (EC), nylon (EN), linen (EN), polyester (EP) with epoxy resin as published. 20ml of Hydrogen peroxide was mixed with colbalt and methyl ethyl ketone to form mixture 1, 20ml of borax was mixed with cobalt, and methyl ethyl ketone peroxide to form mixture 2. 40ml of epoxy was measured out in a beaker and poured into a basin and 20ml each of mixture 1 and 2 were injected gradually at different points in the basin. The grey fabrics were then dipped in each of mixtures to form epoxy coated grey fabric. The methyl ethyl ketone peroxide (MEKP) and cobalt were used as catalyst and accelerator respectively. The grey fabric were then dipped in the mixture of 1 and epoxy and 2 and epoxy to form epoxy coated grey fabrics and allowed to cool at room temperature. The epxy grey coated fabrics were totally immersed in water bath at temperatures of 18°C and 27°C at intervals of 300 seconds until equilibrium was reached. Sorption properties were calculated using the molar percentage uptake (qt) obtained from molar uptake at equilibrium (qe). The results obtained were validated using the least square technique with Matlab software. The epoxy grey coated fabrics were characterized using Scanning Electron Microscope (SEM) and Fourier Transport Infrared Spectroscopy (FTIR) to examine the internal structure, and functional groups. Results obtained indicated that the molar uptake of both composites followed the typical isotherm curves. The enthalpy of sorption obtained was positive and suggested Henrys type of sorption. The epoxy coated grey fabrics reached equilibrium at shortest time for the 18°C while 27°C took longer time. Elemental composition of the epoxy coated grey fabrics were obtained using the elemental dispersive X-Ray from SEM; they indicated presence of carbon, oxygen, sodium, potassium, silicon, calcium, aluminum, magnesium and iron.

Abstract

Red palm oil is a carotenoid-rich lipid source with functional potential, but its bioactive compounds are susceptible to oxidative degradation during processing and storage. This study aimed to develop red palm oil emulsion hydrogel beads using sodium alginate and bacterial cellulose as encapsulating materials and to evaluate the effect of their ratios on physicochemical and encapsulation properties. Beads were prepared by emulsion ionotropic gelation using CaCl₂ as a crosslinking agent. A completely randomized design with five treatments and three replications was used, and data were analyzed by ANOVA followed by Duncan’s New Multiple Range Test at a 5% significance level. The sodium alginate-to-bacterial cellulose ratio significantly affected yield, bead size, sphericity factor, swelling capacity, total carotenoid content, and encapsulation efficiency. Increasing bacterial cellulose proportion improved bead yield, diameter, carotenoid retention, and encapsulation efficiency. Treatment E, containing 50 mL sodium alginate, 25 mL bacterial cellulose, and 25 mL red palm oil emulsion, showed the best characteristics, with 63.17% yield, 3.55 mm bead size, 0.004 sphericity factor, 44.47 µg/g total carotenoid content, and 83.21% encapsulation efficiency. These findings indicate that sodium alginate–bacterial cellulose hydrogel beads are promising encapsulants for carotenoid-rich red palm oil emulsion.

Abstract

Biocomposites are materials composed of a combination of polymer matrices and natural reinforcing agents that are environmentally friendly and have the potential to replace non-biodegradable synthetic polymers. The development of biodegradable foam biocomposites represents an innovation in lightweight materials that can be applied as sustainable packaging. This study aimed to examine the effect of microcrystalline cellulose (MCC) concentration on the characteristics of foam biocomposites and to determine the optimal concentration to produce the best quality foam. The research employed a Randomized Block Design (RBD) with three MCC concentration treatments (1.5%, 3.5%, and 5.5%) across three gelatinization times (1 minute, 2 minutes, and 3 minutes). The observed variables included tensile strength, density, tear resistance, compression set, thickness, swelling, elongation at break, and biodegradation time. The data were analyzed using Analysis of Variance (ANOVA) followed by the Honestly Significant Difference (HSD) test. The results showed that MCC concentration and gelatinization time significantly affected tensile strength, density, tear resistance, compression set, thickness, swelling, elongation at break, and biodegradation time. The best foam biocomposite was obtained at 5.5% microcrystalline cellulose concentration and 1 minute of gelatinization time, with tensile strength of 5.04 N/cm², density of 0.38 g/cm³, tear resistance of 3.60 N/cm², compression set of 19.99%, thickness of 15.11 mm, thickness swelling of 1.22%, elongation at break of 3.02%, and biodegradation time of 13 days.
