Pioneering Seaweed Farming to Revolutionize Food, Sustainability, and Ocean Conservation

Finding it's home on the Yorkshire coastline, SeaGrown is a pioneering company leading the way in sustainable seaweed farming in the UK. Based in Scarborough, this innovative venture is harnessing the power of the North Sea to grow and harvest nutrient-rich, environmentally friendly seaweed, offering a versatile, sustainable, and delicious ingredient to chefs, food lovers, and businesses across the country. With a strong commitment to marine conservation, sustainable food production, and reducing carbon footprints, SeaGrown is not just cultivating seaweed—it’s creating a blue economy that benefits both people and the planet.

A Mission for Sustainability and Ocean Restoration

Unlike traditional farming, seaweed cultivation requires no fresh water, no fertilizers, and no pesticides, making it one of the most sustainable food sources on the planet. SeaGrown has taken full advantage of this natural wonder by establishing the UK’s first offshore seaweed farm, where their crops grow naturally in the nutrient-rich waters of the North Sea. As they expand their operations, they’re also working to restore ocean biodiversity, creating habitats that support marine life and improve water quality.

Seaweed is often referred to as a “climate superfood” because of its ability to absorb carbon dioxide, produce oxygen, and combat ocean acidification. By growing seaweed on a large scale, SeaGrown is helping to reduce carbon emissions while providing a sustainable alternative to land-based crops that require extensive resources to cultivate.

The Power of Seaweed: A Superfood with Endless Benefits

Seaweed is a nutritional powerhouse, packed with essential vitamins, minerals, and antioxidants that provide numerous health benefits. It is rich in iodine, essential for thyroid function, and contains high levels of fiber, protein, and omega-3 fatty acids, making it a fantastic addition to a balanced diet.

SeaGrown offers a range of natural and dried seaweed products that can be used in various ways:

  • Cooking & Seasoning – Sprinkle dried seaweed flakes over soups, salads, or seafood dishes for an umami-rich flavour boost.
  • Plant-Based Nutrition – A perfect ingredient for vegan diets, providing natural iodine and essential nutrients.
  • Sustainable Alternative Ingredients – Used in food production as a natural thickener, salt replacement, or flavour enhancer.
  • Health & Wellbeing – Packed with minerals that promote gut health, support the immune system, and improve skin health.

By bringing wild and farmed Yorkshire seaweed to kitchens across the UK, SeaGrown is introducing more people to the incredible versatility and benefits of this ocean superfood.

Beyond Food: Seaweed’s Role in a Sustainable Future

SeaGrown isn’t just focused on food—they’re also exploring seaweed’s potential in biodegradable packaging, cosmetics, pharmaceuticals, and even biofuels. With growing concerns about plastic pollution and unsustainable farming practices, seaweed presents an exciting eco-friendly solution across multiple industries.

By investing in research and innovation, SeaGrown is at the forefront of marine-based sustainability projects, proving that the ocean holds the key to a greener future. Their work in developing seaweed-based alternatives for commercial industries highlights the vast potential of this remarkable marine crop.
