“…Table 7 summarizes some studies conducted using agro waste and synthetic reinforcement materials. Common agro waste materials reported in the literature include ashes of palm kernel shells [181], rice husk [41,62,106], cassava peel [58], green plantain peel [54,182], coconut shell [39,64,183], groundnut shell [55], corn cob shell [184], bamboo leaf ash [156,185], and lemon grass [43]. Various processing routes have been employed to fabricate agro waste-based reinforcement hybrid composite materials, including FSP, double stir casting (DSC), stir casting (SC), two-stage ultrasonic SC, stir-squeeze casting, and hybrid precursor system.…”

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.

“…NCRs exhibit high strength, improved hardness, and enhanced wear resistance as the load on the matrix is e ciently transferred onto these reinforcements. Examples of NCRs that have been utilized in production of AMCs include rice-husk ash (RHA) [12][13][14], coconut-shell ash (CSA) [15][16][17][18], palm-kernel shell ash (PKSA) [6,19,20], corn cob ash (CCA) [21], date palm seeds ash (DPSA) [22], bean pod ash (BPA) [23][24][25][26], groundnut shell ash (GSA) [27], plantain peel ash (PPA) [28,29], bamboo leaf ash (BLA) [30,31]. For example, when combined with alumina as reinforcements in Al-Mg-Si matrix, RHA was reported to produce lightweight composites [9].…”

The AA6063 alloy, renowned for its effective resistance against corrosion and favourable mechanical properties, has limited applications within the automotive and aerospace sectors owing to its reduced hardness and wear properties. Manihot esculenta and Plantago major are essential food crops cultivated largely within sub-Saharan Africa. The peels of these food crops contribute to environmental pollution through indiscriminate disposal. This study aims to contribute to the current understanding exploring the potential use of the Manihot esculenta peel ash (MEPA) and Plantago major peel ash (PMPA) as innovative reinforcements for in-situ fabrication of AA6063/Al2O3 hybrid composites. Comparative assessments of the hardness behaviours and wear performances of MEP-based aluminium matrix composites (AMCs) and the PMP-based AMCs reveal MEP’s superior impact, enhancing AA6063 matrix hardness to 107 BHN, in contrast to PMP’s 86 BHN. MEP and PMP particulates as reinforcements notably improved AA6063 hardness by 328% and 244%, respectively. Incorporating the ashes of these solid wastes also enhanced the abrasion resistance of the fabricated AMCs. While the MEP ash particles performed better than the PMP ash particles in hardness and wear, natural ceramic agro waste reinforcements (MEPA and PMPA) provide an economical alternative to expensive artificial ceramic reinforcement (Al2O3). These findings highlight the potential of using MEPA and PMPA agro wastes as sustainable engineering solutions to reinforce AMCs for improved applications.

“…Coconut shells may be used to make many value-added products, and charcoal and activated charcoal are often utilized for their adsorption properties [4,5]. Coconut shell composite is cheaper and ecological [6][7][8]. Coconut shell particles transmit the matrix's load, and considerably affect the composite's mechanical properties.…”

“…Both later lost value. Kumar et al [7] discovered that property values increased in hybrid nano-metal matrix composited (HMMC) AA7075 reinforced with nanomicrosized particulated Al 2 O 3 and coconut shell ash (CSA). Ultrasonic-assisted stir-casting mixed Al 2 O 3 and CSA, and mechanical, thermal, and corrosion data were examined.…”
