The pollution of leather industry contains a wide variety of toxic substance. Many diseases are spread by these viruses, which enter the body through the mouth and nose. Leather industry waste that contains chrome is another sort of trash. Chrome Containing Leather Waste (CCLW) also generates various types of pollution. The study's response parameters are surface quality and energy consumption, while the machining parameters are cutting speed, feed rate, and depth of cut. The ideal set of machining settings, including those for minimal surface roughness and minimum energy consumption, have been determined using the response surface methodology (RSM). CCLW is used as primary reinforcement while for secondary reinforcement particle alumina has been utilized. Stir casting parameters were optimized using Response surface methodology (RSM), collagen was preheated at temperature 177.36°C, weight percent of collagen 1.43, stirring duration of stir casting is 180 s, alumina preheat temperature of 300°C and alumina weight percent of 5 has been determined to be best amalgamation of casting parameters. At optimal combination of characteristics, tensile strength of prepared composite was determined to be 162.45 MPa, composite tensile strength was increased by around 20.33 %.
