Eggshell Powder Filled Starch Green Composites

The impact of incorporating eggshell microparticles on corn starch (CS) was examined regardingwater absorption, tensile strength, Izod impact, and thermal properties. The study revealed that theeggshell particulates exhibit proper interactions with starch. It was observed that initially, the waterabsorption of starch composites reinforced with eggshell powder (ESP) decreased upon addition ofeggshell microparticles, followed by an increase. Incorporating eggshell powder into corn starchresulted in a decrease in tensile strength and Young's modulus of the samples, while the elongationat break remained relatively constant. By increasing baking time, the samples' flexibility decreased,leading to a more brittle composites. Also, the thermoplastic behaviour was observed in samples
