Calcium Carbonate Market to Reach a Value of ~US$ 28 Bn by 2027 Global Calcium Carbonate Market: Key Highlights In terms of value, the global calcium carbonate market is anticipated to expand at a CAGR of ~6% from 2019 to 2027. Calcium carbonate is widely used as a filler or pigment in paper, plastic, and paints & coatings. It is also used as a dietary supplement. The demand for precipitated as well as ground calcium carbonate in these enduse industries has been continuously rising. As such, the global calcium carbonate market is estimated to expand at a steady pace during the forecast period. Calcium carbonate is used as an inexpensive dietary calcium supplement and antacid. Other applications of calcium carbonate are the polishing and cleaning of rice, and as a cleaning component in shoe polish. According to research conducted by the Washington University in St. Louis, Missouri, in 2016, the growth of cancerous tumors can be restricted using nanoparticles of calcium carbonate. Nanoparticles act on the pH of tumors, and change the pH from acidic to alkaline. Researchers are striving to determine the compatibility of calcium carbonate nanoparticles with chemotherapy drugs, and the optimal dose of these particles to prevent the metastasis of tumors. The usage of calcium carbonate nanoparticles as a measure against cancer is a new development in the medical field. This is expected to boost the demand for calcium carbonate in the healthcare industry. Regulatory Framework for Mining Calcium Carbonate to Hamper Demand Rise in human health and environmental concerns due to release of toxins such as dioxins and dioxin-like polychlorinated biphenyls during calcium carbonate mining is restricting the growth of the global calcium carbonate market. A large number of regulatory approvals are required to mine calcium carbonate from its reserves. This factor may hamper the global calcium carbonate market during the forecast period. Calcium carbonate is mined from limestone. Limestone is essential for maintaining underground water levels, and excess mining of calcium carbonate could lead to water depletion. Dust released during quarrying limestone affects the health of individuals. It causes allergy in the eyes, nose, mucous membrane, and skin of human beings. Exposure to this dust also causes coughing, sneezing, and nasal irritation. Thus, Occupational Safety and Health (OSHA) mandates certain industrial practices, such as the use of respirators when the concentration of calcium carbonate exceeds the prescribed limit in the U.S.
