Green composites were prepared by recycling waste Aluminum and ceramic debris of marble and granite stones obtainedduring stone cutting at building construction sites. The composites were developed using the most economical stir castingprocess under ambient conditions with five weight percent of white marble powder and black granite powders. Themicrostructure characterization was done with my optical and SEM micrography as well as XRD. The microstructure showsfair particle distribution and improved hardness by 22-25% than the base matrix. The tensile strength and elastic modulusalso improved. The density remained stagnant due to porosity. A decline in elongation and impact strength was observed. Thestudy recommends using waste Aluminum and waste ceramic powders to develop green composites for non-critical industrialapplications such as structures, furniture, stationary machine parts, and automobile chassis.
