Ball Milling Eggshells and Starch: Unveiling a Sustainable Material in theCircular Economy

This study investigates the potential of ball milling as a high-energy grinding process, to create biobasedfillers from waste materials. We explore the combination of starch, a readily availablebiopolymer, and eggshells, a considerable source of calcium carbonate (CaCO3) waste. Thisapproach aligns with the circular economy principles by utilizing waste products to generatefunctional materials. This research focuses on the production of nanoparticles from eggshells throughball milling with starch. Ball milling time reduces particle size, as analyzed by X-ray diffraction(XRD), scanning electron microscopy (FESEM) and Fourier transform infrared spectroscopy (FTIR)analysis of functional groups.This research holds promise for the development of eco-friendly andpossibly functional fillers for the plastics industry, contributing to a more sustainable future
