Mass cultivation of northern diatoms: Turning pollution into capital

Hans-Christian Eilertsen, Professor
UiT - The Arctic University of Norway
There are many initiatives aimed at mass production of microalgae. Potential products are biofuel, food, feed, pigments and pharmaceuticals. Economic sustainable production is though hindered by expensive and complicated low-yielding photobioreactors and high processing costs.
 
Our project is a cooperation between UiT The Arctic University of Norway and the ferrosilicon producer Finnfjord AS. We have, as of today, 26 000L reactors installed and integrated in the production line at the factory. Our successful project concept is completely different from other initiatives. It offers solutions to the above-mentioned economic obstacles by offering new and innovative solutions that reduce cultivation and processing costs, while at the same factory CO2 and NOx outlets are reduced. The microalgae we apply are photosynthetic efficient, lipid-rich diatoms with high CO2 sequestration abilities, adapted to northern temperate climates. Our primary product will be (fish) health promoting fish feed, but other products (e.g. from bioprospecting) are also included.
