There is a high content of calcium carbonate in mussel and oyster shells, which can be used in the formulation of medicine, in construction or as filler in polymer materials. Most of the world’s Calcium Carbonate comes from Limestone mining, which the researchers describe as “ecologically harmful and unsustainable”. The Calcium Carbonate derived from the Limestone mining has a lot of heavy metals as compared to the Oyster Shell Calcium Carbonate and hence it becomes an excellent source for calcium supplements as well as fillers in many Polymer and Pharma Industries, due to the nature of Oyster Shell Calcium Carbonate. Moreover, the Oyster Shell Calcium Carbonate being an organic material is ecologically biodegradable and is free from heavy metals and toxic substances.
