EXTRACTION OF CALCIUM CARBONATE FROM WASTE

2020-1-30 · Mineral limestone, which is made of calcium carbonate (CaCO 3) is used as filler materials for polymer composites to reduce the cost and improve certain properties. On the other hand, eggshells contain high amounts of CaCO 3 with some organic membranes but are generally considered as a waste.
