This study investigated the extraction of calcium chloride (CaCl2) from chicken eggshell waste. The objective of the study was to extract calcium as calcium chloride from waste of eggshell and characterize the physio-chemical properties of extracted calcium chloride. Calcium chloride was obtained using 4% and 5% hydrochloric acid (HCl) solutions, and the drying time was optimized to maximize yield. Analysis of a 2g sample of the extracted CaCl2 revealed an ash content of 1.71g (85%) and a moisture content of 3.4%. The resulting calcium chloride exhibited high solubility in water. The optimal extraction conditions were achieved using a 5% HCl solution with a drying time of 3hours, yielding 7.2g of CaCl2 per 10g of eggshell powder, corresponding to 72% anhydrous calcium chloride. Chicken eggshells, typically considered waste and discarded into the environment, contribute to pollution despite their high calcium content. Extraction of calcium in the form of calcium chloride offers a sustainable approach to waste valorization. Calcium is an essential nutrient involved in numerous biological processes, including nerve and muscle function, cell division, blood coagulation, and the prevention of chronic diseases such as osteoporosis. This study aimed to extract calcium from eggshell waste and characterize the physicochemical properties of the obtained calcium chloride, providing a potential solution for eggshell waste management and contributing to human health through calcium supplementation.
