Calcean
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.
