Seaweed Farming news from around the world.

December 2025

15th December - Are you interested in Seaweed as a food? Do you have a recipe idea? If so, speak to us about your exciting ideas.

12th December - Ulva Sea Farms is looking closely at farming Ulva, including Ulva Intestinalis. These macroalgae show promise as a natural alternative to man-made biotics. Want to know more? email us ulvaseafarms@email.com

We are excited to announce a partnership with a Tunisian company to farm Ulva and Gracilaria verrucosa off the coast of Tunisia. The Ulva will be used to produce extracts, mainly Polysaccharides and the Gracilaria for a thickening agent. If you are interested in investing in this large-scale project, please do not hesitate to contact us.

Our interest in rare earth minerals paid off this month when we analysed the invasive Sargassum, growing off the Cornish coast. It showed minute particles of Lithium within the biomass, proving that seaweeds can contribute to the capture of these precious metals. Please email for more information.

For the last eight months, we have been trialing new technology to remove rare earth elements from seawater using a number of innovative ways, including the device pictured in the photo above. We've called it Bob, as it doesn't have an official name yet; it simply bobs up and down in the sea, utilising solar power to extract micro particles of rare earth minerals from seawater.  

How does it work? Here's a simplified image of the process.

As you can see from the chart above, there is an immense amount of much-needed rare earth minerals in our oceans. The question is, what is the most cost-effective method to capture these minerals?

Another method we are looking to use is the water tumbling method, where seawater close to known REE sources is pumped into Ulva tanks. Ulva is known to attract rare earth elements, and this method allows the Ulva time to capture the minute particles within its biomass. The biomass is then dried, and the dried seaweed is removed, leaving the minerals behind.
