The technology of green synthesis of calcium acetate from quail egg shells

Abstract

The concept of sustainable development is centred around recycling waste materials generated by the agro-industrial complex. One of the ways to achieve this is by using biowaste derived from food products, such as quail eggshells, as a sustainable and eco-friendly raw material to replace limestone or carbonate stone in the production of calcium acetate (Ca(CH3COO)2·H2O). This research shows the possibility of producing calcium acetate in laboratory conditions by chemical transformation with acetic acid using quail eggshells as the raw material. 50 g of quail eggshells were subjected to chemical treatment with 10% acetic acid, producing 60.09 g of calcium acetate monohydrate, with a maximum yield of 76%. The X-ray diffraction data of the resulting product strongly suggested the presence of calcium acetate, and the crystallinity of the salt was found to be 72.57%. Based on these observations, it can be concluded that quail eggshells can be used as an alternative raw material for producing calcium acetate in a sustainable manner.
