Abstract. Calcium carbonate-based shells represent another large group of agro/biowaste. The overview of high-energy milling processing of eggshells, oyster shells, shrimp shells, other shells (e.g. nacre or scallop shells) and bones employing mechanochemical processes is provided in this chapter. The main application area of …

Calcium carbonate is abundantly available in nature as limestone, chalkboard, or marble and CaCO 3 fillers from these minerals can be produced at very low cost. Three forms of CaCO 3 fillers are used; arranged in the order of purity, they are dry processed, beneficiated, and precipitated. Calcium carbonate is considered a soft, nonabrasive filler.
