Agro-marine waste presents environmental challenges, demanding sustainable solutions. This study explores the potential of ashes from periwinkle shells, plantain stems, and eucalyptus wood for sustainable material use. Physical analyses reveal Periwinkle Shell Powder (PSP) with the highest bulk density (0.52–1.24 g/cm³) and specific gravity (2.05),...
This study investigates the valorization of Periwinkle Shell Powder (PSP) as a sustainable and cost-effective reinforcement material in AA6061 aluminum composites. The incorporation of PSP enhances the microstructural, thermal, and mechanical properties of AA6061, demonstrating its potential for improved performance and sustainability. Microstructu...
This study presents the development and evaluation of AA6061 hybrid composites reinforced with plantain fiber ash (PFA), eucalyptus wood ash (EWA), and periwinkle shell powder (PSP) to enhance mechanical properties while promoting sustainable manufacturing practices. Hybrid composites were fabricated with varying reinforcement ratios and characteri...
Aluminum-based composites reinforced with agro-marine waste materials present an eco-friendly, cost-effective solution for industries needing lightweight and durable materials. This study develops and evaluates the mechanical properties of aluminum (AA6061) composites reinforced with plantain stem ash, eucalyptus wood ash, and periwinkle shell powd...
Introduction: This study examines the microstructural and mechanical improvements in AA6061 hybrid composites reinforced with agricultural and marine waste materials: plantain fibre ash (PFA), Eucalyptus Wood Ash (EWA), and Periwinkle Shell Powder (PSP). The goal is to enhance mechanical properties while promoting sustainable manufacturing. Methods...
The number of waste tyres is on the increase, because of the growing use of transport vehicles. Almost one trillion waste tyres are generated in the world annually. Established methods of disposal, recycling and re-use of waste tyres have failed to keep pace with generation, proven to be ineffective, cost-intensive and in some cases environmentally...
The use of agro-marine waste particulates in composites has gained attention as a result of the desire for sustainable and cost-effective materials. In this review, the biomechanical and crystallography properties of AA 6061 alloy reinforcement of various agro-marine waste particulates were investigated, including sugarcane bagasse, fly ash, coconu...
This study utilizes response surface methodology (RSM) to estimate the engineering parameters of PFAP/silumin composites. The tensile strengths of the developed composites were evaluated using a Box-Behnken design (BBD), considering factors such as weight fraction, particle size, soaking time, plantain fiber ash particulate concentration, and silum...
The management of waste products may reduce pollution and dumping sites. Therefore, one of the main goals of contemporary research is to recover these wastes through conversion into a more environmentally acceptable material that applies to fabrication engineering. This study demonstrated that waste products such as plantain waste are good reinforc...
Sugarcane bagasse (SB) and Coir fibre (CF) are two cellulose fibres/agricultural waste products found to constitute great environmental challenges, this has initiated a need to study them for probable potentialities as alternative use in the field of material science and engineering development apart from their localized usage. Consequently, this p...
Ecofriendly, ecoefficient and sustainable civil engineering work has been research with emphasis on
adapting the byproducts of solid waste recycling and reuse to achieving infrastructural activities with low
or zero carbon emission. The direct combustion model, "the solid waste incinerator caustic soda oxides
of carbon entrapment model" (SWI-NaOH-O...
