“…The OH stretch is a strong, broad band often detectable between 3400 and 3300 cm −1 , and it offers crucial underlying information on the hydrogen bonding environment and other functional groups in its surroundings. The finding agrees with the data reported in prior work on the utilization of natural filler in composite materials 93,94 . FTIR spectral analysis further reveals that alcohol groups with a broad and strong intensity (i.e., secondary CHOH) also showed up at 3328.45 cm −1 44 …”

Creating environmentally friendly materials like polymer matrix composites (PMCs) enhanced with natural fillers has grown in recent decades. It supports the United Nations sustainable development goals (SDGs) by reducing the reliance on non‐renewable resources, minimizing waste generation, and promoting sustainable land and water management practices. This investigation assesses the viability of employing Elaeocarpus ganitrus (rudraksha) seeds as a filler (rudraksha seed filler [RSF] in environmentally sustainable composite materials. Various loading concentrations and sizes of RSFs were incorporated by hand lay‐up into polymer epoxy resin (ER). The effect of filler on the mechanical properties of composites was observed. Thermal properties of RSF/epoxy composites were investigated using thermogravimetric analysis (TGA) and Fourier transform infrared (FTIR). The 10 wt% 100‐mesh filler had the maximum tensile strength (TS) at 42.30 MPa and flexural strength (FS) at 87.4 MPa, surpassing other filler sizes and loading concentrations. Meanwhile, the highest impact properties have been achieved with 20 wt% of RSF with 0.436 J. The results of this study highlight the significant impact of filler type and concentration on the mechanical properties of the material. These findings offer valuable insights that may be applied to various industrial contexts. Furthermore, incorporating 10% up to 30 wt% RSF in epoxy composites has brought more thermal stability than virgin epoxy. It revealed that the RSFs possess higher decomposition temperatures than the epoxy matrix. RSF has a potential sustainable reinforcement in polymer composites and holds great promise for addressing environmental challenges and aligning with several SDGs.Highlights Interest in eco‐friendly materials, like polymer composites with natural reinforcements, has been increasing in recent decades. Rudraksha sees filler is lightweight with low moisture, high carbon content, and some mineral elements. The addition of Rudraksha seed filler has enhanced the tensile, flexural, and impact properties of the composites. Rudraksha seed filler possess higher decomposition temperatures than the epoxy matrix. Rudraksha seed filler has a promising future as a sustainable friction material for automotive brake pads.

“…In this way, it can be stated that other factors, such as water content, starch content, and starch-sodium metasilicate ratio-analyzed in our work-can lead to an increase in the bending strength of the panels by approximately two times. Similar results are obtained when modified starch is used [32][33][34]. In this case, the bending strength is significantly higher.…”

“…The works of other authors show that the performance properties of the boards created with starch binding material, especially the bending strength, can differ several times [17][18][19][20][32][33][34]. This is largely due to the density of the panels.…”

In the current study, high-strength boards for the construction industry were developed from renewable natural resources, fibrous hemp shives, and corn starch. During the research, the influence of the composition of the mixture, the processing of raw materials, and technological parameters on the operational properties of the board were evaluated. The influence of the binding material and the water content on the properties of the molded boards was evaluated. It was established that the rational amount of starch is 15% of the mass of the shives, and the amount of water is 10%. It has been established that with the proper selection of the forming parameters of the board, it is possible to avoid internal disintegration of the structure due to the water vapor pressure, increase the bending strength, and ensure uniform sintering of the board throughout the entire volume. It was found that additional processing of hemp shives can increase bending strength by more than 40%. Furthermore, during the processing of shives by chemical means, soluble substances are washed out, which reduces the density and thermal conductivity of the shives. Selection of a rational level of compression allowed us to increase the bending strength of the boards by 40%. The assessment of all factors made it possible to obtain boards with a bending strength of 40 MPa. The additives used made it possible to reduce the water absorption of the boards up to 16 times and obtain non-flammable boards. The thermal conductivity of the resulting boards varied from 0.07 to 0.095 W/(m·K). The analysis of macrostructure and microstructure allowed us to evaluate the process of the formation of bonds between hemp shives.

“…Recent technological advancements have led to the development of bio-based packaging materials made from biomass polymers such as starch, cellulose, lignin and chitin, such as biocomposites using natural fibers [5][6][7][8][9] . These compostable materials possess similar functionality to petroleum-based synthetic polymers, such as their structural integrity, flexibility, and versatility in various applications, but offer the added benefits of being inherently biodegradable.…”

Biocomposites have gained attention in the packaging industry due to their potential as sustainable alternatives to conventional synthetic materials. In this study, novel cotton incorporated poly (lactic acid)/ thermoplastic starch biocomposites were developed for packaging applications using in short shelf life products the extrusion method. Pelletized samples obtained by extrusion were stamped from plates obtained by compression and were characterized through measurement of density, hardness, contact angle and water absorption, as well as Fourier transform infrared spectroscopy (FTIR), thermal analysis and scanning electron microscopy (SEM). No significant changes in the density results were observed. A slight increase in the hardness of formulations in relation to the PLA was associated with the presence of cotton fiber in biocomposites. The FTIR results revealed physical interaction of PLA, TPS and cotton fiber. By DSC analysis, for all formulations the melting exhibited only one peak, suggesting good homogeneity and interaction among the components, as observed by TG/DTG results, and corroborating SEM analysis. The biocomposite PLA/TPS/Cotton 85/10/5 wt.% displayed greater increase in water absorption than both 95/5/0 and 90/5/5 wt.% formulations, which can be attributed to the increase in starch proportion, confirming the contact angle results. The hydrophilic tendency corroborated the biodegradation process in the packaging end-of-life.
