Sea & Sun Organic

Since 2011 Sea & Sun Technology is running an algae cultivation plant. Besides the production of other algae like Arthrospira platensis (Spirulina) we are aiming on the production of natural Astaxanthin from Haematococcus pluvialis (“Made in Germany”). The greenhouse with a total area of 6000 m2 is currently equipped with Open Raceway Ponds with volumes from 4.000 – 50.000 L each as well as photobioreactors (bubble columns, flat plate) with a total production volume of 8.000 L. Machines for the downstream processing (centrifuge, chain mill, spray dryer) are available.
To ensure the quality of microalgae products and to improve our work scientists from interdisciplinary fields are working in the R&D lab. Together with several universities and other companies various microalgae-projects have been implemented within the last years.
