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

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(CH 3 COO) 2 ·H 2 O). 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.
