Low Carbon Food Colorings

Oterra x VAXA Technologies have partnered to launch 'Arctic Blue,' a natural blue colorant derived from spirulina cultivated through an advanced, carbon-neutral process. Unlike conventional spirulina farming, this innovative method uses closed bioreactors powered by geothermal energy, drastically reducing land and water use. Positioned between Europe and the U.S., the facility provides an eco-friendly alternative to artificial colorants, helping food and beverage brands lower Scope 3 emissions while maintaining vibrant color and high pigment strength.

This advanced spirulina production eliminates common issues of open pond cultivation, such as strong odors, while ensuring ease of use in food applications. Arctic Blue maintains spirulina's rich, natural color but dissolves more efficiently, making it ideal for confectionery, bakery, and frozen desserts. With growing consumer demand for natural ingredients, this partnership sets a new benchmark for sustainable food coloring solutions. Oterra’s collaboration with VAXA exemplifies how innovation can drive environmentally responsible alternatives without compromising performance.
