Seaweed Farming news from around the world.

Welcome to 2026.

New for 2026 - Ulva Sea Farms are exploring the use of Ulvan extracts to make an alternative to man-made antibiotics. As you probably know, the overuse of these antibiotics has led to the viruses becoming resistant to the antibiotics. Our research into an alternative antibiotic from Ulva can change all that. Please email for more details.

January 26. We appreciate that not everyone can afford to invest in a large seaweed project or a complete Ulva Pen. Therefore, we are offering bite-sized pieces to test the water, so to speak. For this month only, you can invest in a part of an Ulva seaweed Pen for just £500 GBP. This will give you one 7th of the Ulva grown in an Ulva Pen and one 7th of the profits. A 7th of the Ulva grown in an Ulva pen is approximately 2000 Kg of wet Ulva seaweed. The selling price is between 40p and 50p per kilogram, giving you a return of between £800 and £1000 per season. The initial investment will run for five years. For more information, terms and conditions and the legal agreement, don't hesitate to get in touch with us at ulvaseafarms@email.com or call 07955 232363

Project Africa  2026.

We are actively seeking interested parties and funding to establish seaweed farms off the coasts of Kenya and Somalia.  Please contact us for more details.

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

November 2025

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.  

October 2025 News.

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.

September 2025

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.
