“…Inorganic NRs derived from synthetic minerals like fibers and metallic reinforcement have also been reported [91]. NRs are also called green reinforcement materials (GRM), AWs, biofibers, biofillers, or natural fibers [6,52,92,93], reflecting their derivative source from agricultural-based biomass. Like SRs, NRs are utilized to enhance the mechanical, corrosion, and thermal performane of composites and to produce lightweight materials for various applications in engineering, building, construction, energy storage, transportation, and more [94][95][96][97][98].…”

“…Thirdly, AWs are cost-effective due to their natural recyclability and abundance, resulting in lower processing costs than synthetic alternatives [197]. Furthermore, agro waste materials as renewable resources reduces dependence on finite resources [93,198]. Lastly, AWs are biodegradable organic byproducts [18], which can be further processed into ash for sustainable engineering repurposing, making them environmentally biodegradable.…”

The utilization of agro waste as reinforcement in metal matrix composites (MMCs) has sparked interest regarding its feasibility and sustainability in engineering practices. Compared to synthetic reinforcements, its efficacy as a potentially cost-effective and environmentally friendly alternative has been explored by diverse studies. This review critically examines existing literature on agro waste-based reinforced MMCs, evaluating experimental findings on mechanical, tribological, density, and corrosion performance from a sustainable engineering perspective. Furthermore, it explores the innovative strategy of employing multi-component metal matrix composites to fabricate composites with improved performance attributes. The utilization of multi-component reinforcements has the capability to tackle issues like the challenge of disproportionate reduction in ductility and toughness peculiar to monolithic and hybrid MMCs. Despite promising results in some studies, numerous unexplored research areas and gaps remain, emphasizing the need for further investigation to provide valuable guidance for future research and development of agro waste in sustainable engineering applications.

In the global pursuit of using sustainable component materials, reinforcement materials derived from agricultural straw waste have attracted widespread attention to develop polymer composites. However, the polar and hydrophilic properties of straw fibers limit their interfacial adhesion behavior, which leads to poor physico‐mechanical and tribological properties of the resulting polymer composites. In this work, cotton straw fibers (CSFs) were derived from agricultural cotton straw wastes, and then were treated with sodium hydroxide solutions of different concentrations (0–7 wt.%). Physical and mechanical properties were analyzed and tribological properties of the developed CSF reinforced polymer composites were investigated systematically. The experiment results indicated that the incorporation of treated‐CSFs in the polymer composite had less effect on the density, whereas it significantly enhanced the water absorption, impact strength and tribological properties. The worn surface morphology analysis revealed that the addition of the treated‐CSFs is conducive to the formation of the contact plateaus, which is in turn beneficial in improving the wear resistance of the treated‐CSF reinforced polymer composites. Overall, the developed polymer composites reinforced with the treated‐CSFs have shown better physico‐mechanical and tribological properties. The present work confirms the possibility of using agricultural corn straw waste as reinforcement fibers, and then paves the path for the development of future commercial plant fiber reinforced polymer composites.Highlights The usability of cotton straw waste as a reinforcement in polymer composite was investigated. The physico‐mechanical and tribological properties of the polymer composites were evaluated. The alkali‐treated cotton straw fibres were more effective in improving the impact resistance and tribological properties. Use of cotton straw waste in the polymer composite reduced its impact on the environment.

There has been growing interest in using sustainable and eco‐friendly products to produce engineering materials. For this purpose, composite material applications obtained from agricultural wastes are gaining popularity. This study examines the synergistic effect of rice husk and rice stalk wastes on the fade and recovery performance of brake friction composites. Brake friction materials were developed using rice husk and rice stalk separately and in two different weight percentages as a 5–10 ratio in the formulation. For comparison purposes, a reference brake pad using copper as a substitute and a commercially available brake pad were used. Various physical, mechanical and thermal properties were analyzed. The tribological behavior of friction composites was evaluated on the Krauss test device in line with the ECE R90 procedure. The worn surface properties were analyzed using scanning electron microscopy. Tribo test results of friction composites were taken as criteria for performance optimization. While the importance weight of the criteria was determined by AHP, the VIKOR method was used in the sorting of alternatives. The experimental results have revealed that rice husk‐added friction composites had a good coefficient of friction value with better fade and recovery performance compared to rice stalk‐added ones. Increasing the amount of rice husk and rice stalk in the formulation tended to decrease the fade performance; however, it has increased the wear rate and recovery properties. Optimization results have shown that the brake friction composite containing 5 wt % rice husk ranks first in meeting the desired tribological criteria.Highlights Cu‐free rice husk and rice stalk‐added friction composites were developed. Fibrous structure in the matrix developed the contact plateaus. Rice husk‐based tribo‐layer protected the composite from further wear damage. The addition of agro‐waste to friction composites exhibited good potential.
