Kelp seaweed growing on lines

Own a  Seaweed FARM

Seaweed is the futures it has many uses from a sustainable human food to bio fuel, from animal feed and health to edible food packaging.

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 sustainable healthy foods 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 amongst 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 to vegetarianism and veganism you won'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.Seaweed recipe ideas are endless. Or simply sell it in bulk either fresh or dried, Pharmacuitacle, Cosmetics and Agricultural companies buy huge amounts of seaweeds for their products.

                                              The Humble algae is the hot new cash crop — and could be a surprising key to sustaining our growing population.


                         “Seaweed is very important for its natural ecosystem values,” Charles Yarish, PhD, leading seaweed expert and a professor in the department of ecology and evolutionary biology said. “Farming it is a win-win for the environment and the economy.” 

               So, how is it that these rootless sea tangles are on their way to major cash-crop status?


                   Marine plants (most of them photosynthetic algae like seaweed) produce around 80 percent of the oxygen we breathe, meaning if they disappeared from the face of the earth tomorrow, our species would struggle to survive. Seaweed also provides a key habitat for marine creatures, and the first link in the aquatic food chain. Without it, the entire system collapses. It is also the food of the future and is available now!


            But the seaweed is also a nutrient-packed superfood that’s sustainable to grow — it requires no fresh water (an increasingly scarce resource as the planet approaches 11 billion people) and no chemical fertilizers. It also packs a protein- and nutrient-rich punch.  “Kelp is the new kale. Watch out because it’s coming, and it will be everywhere in the next decade.”

            You could argue that seaweed is already everywhere, at least in a subtle way. Mostly grown at thriving farms in Asia, it’s been quietly incorporated into products likely in your pantry and bathroom right now. What’s not being cultivated for food is bought up by other industries. Seaweed extracts are used as textural additives in soups, jams, dressings and ice creams. They’re also a not-so-secret ingredient for brewers, since seaweed makes for a long-lasting, pillowy head on beer. Additionally, from January 2011 through October 2015, 2 percent of body-care products launched globally, including shampoos, lotions and toothpastes, contained seaweed. It may even be the world’s next great biofuel.

             Translation: Seaweed is money. The industry was worth $6 billion globally in 2014, and that number is expected to hit $18 billion by 2021.


              Considering these myriad benefits, Yarish sat down in 2009 while on sabbatical from UConn to contemplate why seaweed farming hadn’t yet taken hold in America and Europe. At the time, the U.S. couldn’t claim a single commercial operation. Today, there are more than 20, with more on the horizon, so let's not get left behind and get the UK seaweed farms on the radar.


             They don’t grow passively. As they mature, seaweeds absorb nutrients from the water, including carbon and nitrogen from agricultural runoff or the burning of fossil fuels. In other words, seaweed is a superhero of the sea, tackling two main culprits:  global warming and ocean acidification. By sucking up these nutrients, seaweed helps restore the pH level of the water, protecting biodiversity threatened by a changing climate. According to the Guardian, if seaweed farms covered just 9 percent of the world’s oceans, we could counteract all human carbon emissions.
