A new method of growing microalgae for animal feed has been trialled in Iceland’s Hellisheidi geothermal park.

Animal Feed by Daiga Ellaby

This method uses LED light, briny water, and CO2 concentrated air as an alternative to land-based cultivation for animal feeds such as soy. The concentrations of these are controlled by photo-bioreactors.

These photo-bioreactors grow microorganisms that recycle carbon, phosphorus, and nitrogen, making a closed-loop process that is much more efficient than traditional agriculture.

This process can provide nutritional content that mimics soybeans at less than 0.6% of the land and water use.
