Bluecal - A sustainable and clean calcium production from seafood waste

Clams from clam fishing and processing get discarded as waste. Main problem for processing has been the lack of knowledge of their chemical potential and the organic tissue that needs to be cleaned off. Sustainable sources of calcium are not many, and most of them demand sacrifices, such as scares from extraction zones and mines, or utilization of the harvesting of vulnerable sea beds. The solution Bluecal aims to utilize waste from clam fishing giving boosting rural fishing areas and giving the market for food calcium a cheap organic and sustainable alternative. Bluecal gives end users the option of buying sustainable calcium products at the same price level as other traditional goods on the market, with the added benefit of lowering environmental impact by avoiding waste being sent to landfills and decreasing energy usage in production stages.
