Pure Algae

Esben Rimi Christiansen from Pure Algae


At Pure Algae Denmark we strive to be forerunners in green and sustainable development. With our innovative technology and mindset, we want to contribute to a circular bioeconomy, where we return more to our planet, than we use of its resources. That is why we have developed Denmark’s first ever land-based facility for a controlled and commercial production of seaweed. Here we can cultivate seaweed of the highest quality, all year round, in an environmentally and climate-friendly manner.
