Meet the production facilities of Spirulina Nigrita...

The production plant is located in Therma Nigrita’s and occupy an area of 2 hectares. The location was suggested by the Aristotle’s University of Thessaloniki as an ideal place for such aquaculture as it combines a certain solar regime with geothermal energy availability. Cultivation and processing of the biomass is done in the facilities of the farm an exemplary vertical unit for Spirulina production in Greece.

Here is performed thw whole production process from aquaculture of the Spirulina, to the packaged finished product, "Spirulina Nigrita". Company is an innovative vertical plant the unique in Greece for the species.

GEO-SPIRULINA Ltd owns 22.5acres of land, with existing greenhouses 7.5acres and ability to put another 5acres of greenhouses.
