Top of the crops

Imagine being able to grow nutrient-dense vegetables without the need for soil, fertiliser or even fresh water? Oh, and this particular plant has the ability to absorb carbon, release oxygen and support biodiversity. Too good to be true?

Welcome to the world of seaweed, an oceanic treasure with transformational properties and the power to paving the way to a sustainable future.

Carbon negative

Seaweed is an extraordinary macro algae contributing around 70% of the total oxygen on Earth. It converts CO2 into biomass through photosynthesis. In fact, some giant kelp species can grow an impressive 50cm daily.
Seaweed is a true powerhouse when it comes to tackling climate change. Not only does it detoxify our oceans but it also produces 70% more oxygen than any plant you’ll find on land. It even absorbs carbon more effectively than trees. This modest, marine marvel is a remarkable eco-friendly carbon solution that we’ve failed to truly appreciate, until now.

Carbon reduction

Seaweed speedily pulls CO2 from the air with every growth spree. Better still is the knowledge that each harvest is a win-win, because when it regrows, it takes more carbon from the atmosphere. And when we add seaweed to our diets, we're capturing carbon and turning it into energy for ourselves. It’s easy to digest and packed with good stuff like fibre, protein, and essential nutrients.

Ocean remediation

Seaweed is a steadfast guardian of the deep. Now more than ever it’s being studied and understood for its importance in marine ecosystems and pollution remediation. It’s a vital player in the effort to preserve and restore the health of our oceans.

Replacing carbon-intensive products

Seaweed can be a replacement for carbon-intensive, land-based agriculture and food systems. Enriched with essential nutrients, seaweed offers a sustainable alternative. It even has the potential to eclipse soy as a protein-rich, delectably umami-flavoured product. Did you know that Kombu, a type of kelp, reigns supreme in umami, surpassing all other food ingredients on land or sea?

Supporting the UN Sustainable Development Goals

Seaweed stands as a linchpin in achieving 9 out of the 17 UN Sustainable Development Goals, which encompass critical social impact. This is something we passionately believe in. We engage and support communities by employing local fishermen in eco-friendly pursuits, create jobs and trigger a positive ripple throughout the industry on both the west and east coasts of Scotland.
