The result of several years of collaboration between the Biogenic Minerals team and local fishermen, manufacturers, and food industry experts, Icecal A is a pure calcium carbonate powder using the neglected source, the Ocean Quahog shell, to provide a high-quality, low-cost product.


Icecal A has been developed to meet the European Union Environmental and Fishery Regulations. By utilizing the unprofitable Ocean Quahog, in which the meat content is not considered worthwhile given the shell makes up the vast majority of a catchweight, we can create a sustainable source of a much-needed product in the form of Icecal A, a high-quality calcium carbonate powder.

ICecal A - Farm is a high-quality calcium powder for use in agriculture.
