Abstract Reducing weight is a crucial factor in automobile industries for structural applications. Waste management includes the collection of storage and recycling of waste. Indians are producing around 230 million tons of waste a year because of the world’s largest population. An attempt was made in varying weight fractions to develop magnesium hybrid composites using the powder metallurgy (P/M) technique. The mechanical properties like micro-hardness, tensile, impact strength are analyzed. The size distribution and physical properties like FTIR, density are tested for magnesium hybrid composites. Microstructure analysis is taken using a scanning electron microscope (SEM), Energy-dispersive X-ray Spectroscopy (EDS) and X-ray powder diffraction (XRD) are analyzed. The waste materials are not only found abundantly but also a threat to the environment. It is a good additive for composite materials, which turns industrial-waste into industrial-wealth. The present study’s hypothesis is the utilization of waste materials into raw materials that solves storage and reduces material cost will favor industrial sectors. The current work examines the tribology using pin-on-disc apparatus by varying applied loads, sliding speeds with sliding distances. Wear debris, and worn surfaces have been analyzed to predict material behavior. The results reveal that superior wear resistance is achieved in AZ91D/7.5% (SiO2–HA) hybrid composite compare with other composites. Keywords Eggshell and agro waste . Mechanical properties .

1 Introduction For many centuries, composite materials exist and consist of two or more constituent materials potential applications over monolithic materials in various engineering fields. The individual components remain separate, and the cost is the primary factor for the materials’ features. The magnesium plays a significant role in fuel-efficient engines in trucks, cars, sea travel, and even high-speed rail. Reducing the weight of a vehicle tends to the

downfall of fuel consumption and emissions [1]. The hybrid metal matrix composites (HMMC’s) evoke a keen interest in achieving high hardness, good wear resistance, and increased fatigue life and light-weight material compared to conventional alloys. Waste materials are a significant issue in today’s life, which shows dissimilarity in health and environmental issues. The quantity and type of agricultural wastes from the different farming process is varying from country to country. In Asia, especially in India, the cultivation
