Circular Algae

We locate, harvest and process harmful algal blooms.


We are Circular Algae. We use satellite and sensor data to detect, predict and collect harmful algal blooms that plague our coastal seas. The removed algae along with removed excess nutrients and heavy metals will help facilitate a more stable sea environment for flora and fauna to return and flourish. We sell the captured algae as an animal feed supplement and for biogas and bioplastic production while saved CO2 equivalent can be monetized to finance our environmental efforts. We service a market spectrum with a combined size of over half a trillion euros. Algae used as fish and animal feed is most environmentally protective as it uses no arable land and feeding cattle algae stops them from producing methane – one of the largest contributors to global warming! By replacing land grown animal feed by wild-harvested microalgae we save 95% of freshwater and reduce the ecological footprint of dairy and meat industry over 50% from current levels.
