A Review on utilization of agricultural wastes as reinforcement for aluminium matrix composites: A Circular Economy Approach

Abstract

Global warming presents significant challenges that demand immediate attention. A number of issues are known to be infamously contributing to this worldwide issue, including industrial operations, the disposal of plastics, electrical devices, and agricultural waste. As world leaders gather to pass rules and regulations to safeguard our planet, researchers have suggested green manufacturing and agro-based alternatives to address this threat. This study challenges synthetic materials like carbon fiber and asbestos, which are known kingpins that can increase landfills worldwide and have detrimental health effects, by demonstrating the feasibility of turning agricultural waste into valuable engineering materials as an alternative manufacturing material. With an emphasis on aluminum matrix, which is a crucial component in manufacturing because of its exceptional qualities, including cheap cost and density, high strength to weight ratio, and resistance to corrosion, among others. According to a review of the literature, fly ash, bottom ash, rice husk ash, and bean pod ash are only a few of the elements that have been used as reinforcement in metal matrix composites. Publicly available research indicates that incorporating agricultural waste particles into a metal matrix in a specific ratio produces a number of desired characteristics, such as decreased greenhouse gas emissions, increased energy efficiency, and improved mechanical performance. The features and applications in several areas were studied in the article. It has been determined that aluminum matrix composites supplemented with agricultural wastes are a viable option for mitigating climate change by lowering CO2 emissions and promoting sustainable production and consumption.
