Seaweed is the future, it has many uses from a sustainable human food to bio fuel, animal feed and health to edible food packaging, eco friendly fertiliser and much more.

Owning or part owning a seaweed farm is an exciting and financially rewarding business, not only will it give you a healthy return and income but you will be an active part of the new seaweed culture; changing the perception of seaweeds, providing healthy alternatives and sustainable foods for both humans and animals.

Growing seaweed offers an excellent income, the seaweed grows during the winter months and only requires minimum tending, it doesn’t need water or fertiliser and once the lines are in the water, they only need to be checked occasionally.

By farming seaweeds, you will not only be helping mankind change it’s perception of this sustainable healthy food but you will also be helping the Oceans and marine life by providing habitat for them and helping remove carbon from the ocean while it grows.

The overwhelming benefits of seaweed are starting to gather pace among well-informed consumers. There is a heightened demand for seaweed in all its forms, with Global Market Insights predicting that the commercial seaweed market will exceed $87 billion by 2024.

It is up to you what you do with your seaweed harvest, however seaweed is very diverse and with more and more people becoming health conscious and more people turning vegetarian and vegan you shouldn’t have any problems selling the seaweed on. You can also process the  seaweed into your own unique products, pickles, breads, chutneys, soups, dried seaweed or simply sell it on. Or simply sell it in bulk either fresh or dried, Pharmaceutical, Cosmetics and agricultural companies buy huge amounts of seaweeds for their products and more recently there has been an increase in interest from Asia, due to the warming seas and pollutants in there own waters.

Green Ocean Farming
Ownership or Partnership?


We are offering two options to own a Seaweed farm in 2021, firstly complete ownership costing approximately £35k – £55k, (in an area of your choice) run by you with our help. We will advise you through the setting up phase and help plan the infrastructure and laying of equipment, including bottom weights / Eco weights / anchors, buoys, floats, lines and importantly supplying 1 Km of  seeded seaweed lines in 100m lengths to go onto the growing lines.

Also help with licensing paperwork and legal documents, advise on harvesting and the sale of your seaweed  (site approval subject to surveys). A licence to farm seaweed is valid for five years after which it will need to be renewed.

The prices quoted exclude the actual license fee and the fee charged by Crown Estate


The second more popular choice is to have your 10 x 100m seaweed lines run alongside ours Pembrokeshire, so we can do the day to day work, checking on buoys and lines where required, checking water quality and temperature and the growth rate of the seaweed.  Also help with finding buyers or selling through us and we can harvest the seaweed for you. The 2021 investment is currently the same for both options £35k. Offer closes 28th Feb 2021.

Growth,  Profit and Returns

The current price for wet seaweed (Kelp) is £4 per kilogram, a 100m line will give you around 1200 + Kg of wet seaweed, some lines may be less some maybe more.

If the seaweed was dried it would command a higher price but obviously there will be a cost in drying and transporting the seaweed.  We can also  help you find a buyer or sell it for you.

Our own seaweeds are destined for food production, bio plastic, fertiliser and biochar. Other uses for UK seaweed are – Animal feed, Bio fuel, Fibres for materials
