Items made from Seaweed Biodigester

Ulva Sea Farms and all things Seaweed.



June  2026 - 1) We have been working closely with a UK biopolymer and moulding company to produce what we believe is the first natural biopolymer made with macroalgae (seaweed). This environmentally friendly material can be used as a realistic alternative to oil-based plastics. Our seaweed biopolymer is compostable, it can also be heated and reused, and it won't break down into microplastics or pollute the oceans. Pictured above are items made from seaweed biopolymer.

For more information or investment opportunities, please email us at ulvaseafarms@email.com or check out our biopolymer web page.


2)  After many months of trials, Ulva Sea Farms is pleased to show our Seaweed Biodigester. Using waste. We convert this seaweed into a rich liquid fertiliser; the byproduct is methane gas, which can be used for cooking.  These unique biodigesters are ideal for helping poorer communities around the world, using a natural waste resource to make plant food and a clean source of fuel to cook with. Our Seaweed biodigesters are cheap to produce. For more information, please email us.    

17th March - Our trial with natural antibiotics made from Ulva is a step closer; unlike synthetic antibiotics, our Ulva antibiotics work equally well but don't have a negative impact on the environment. There are investment opportunities here if you are interested in natural antibiotics derived from macroalgae. For more information, please email us at ulvaseafarms@email.com  


8th March 26 We are actively seeking three individuals to front several cookery episodes, using Ulva, Sea Spaghetti and Kelp as the main ingredients. We will provide the ingredients and recipes. The roles are open to all ages; no prior professional cooking skills are required. Under-16s will need to be supervised. Email ulvaseafarms@email.com to express your interest. 

New for 2026 - Ulva Sea Farms is 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.


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 closely examining the farming of 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.
