Oolitic Aragonite Sand
renewable | biogenic | sustainable
Calcean is changing the way we look at natural resources and their incorporation into familiar products and industries. Calcean utilizes renewable, biogenic calcium carbonate derived from oolitic aragonite sand originating in The Bahamas.
Oolitic aragonite is a renewable and sustainably sourced resource. It naturally forms on the banks of The Bahamas during natural precipitation events called ‘whitings.’ During these events, blooms of cyanobacteria sequester carbon from the atmosphere and a mineralization process occurs, forming oolitic aragonite. Learn more about this process here.
Oolitic aragonite is a versatile renewable resource that provides a number of benefits over standard mined ground calcium carbonate (GCC). GCC is not a renewable resource and has a different morphological structure than oolitic aragonite. Oolitic aragonite’s unique structure affords it many benefits, such as higher surface area, high negative zeta potential, and high calcium bioavailability.
Calcean offers a number of oolitic aragonite-based products in various gradations and particle sizes — perfect for any industry in the world looking for sustainable solutions.
