Leading the Circular Economy Revolution with Seaweed
What Seafields Does.
The leading supplier of sustainable biomass
Seafields transforms harmful Sargassum seaweed blooms into a sustainable, reliable resource for the circular economy. Our unique Algaeponix paddocks secure year-round supply with no supply chain risk, protecting marine ecosystems, fuelling sustainable industries, and removing carbon at scale.
This is allowed through our SeaClear and SeaGrow Solutions, which allow us to catch, cultivate and harvest Sargassum. Creating a valorisation pathway whilst protecting vital Caribbean coastlines.
Our Products.
From coastal protection to industry feedstock
Sargassum Management
We intercept Sargassum at sea with our SeaClear system, stopping harmful blooms before they reach coastline sand protecting fragile ecosystems.
The Seaweed is intercepted behind deflection barriers and then stored in our AlgaePonix paddocks.
Initial Processing
Harvested Sargassum is squeezed, cleaned, and dried, preparing the biomass for conversion into high-value, sustainable and circular products.
Biostimulants
Using our Carbonwave license, we process fresh Sargassum into natural biostimulants that boost crop growth and reduce the need for chemical, fossil-fuel based fertilizers
Dried Pulp
We supply dried pulp to biorefineries for green products. Our seaweed pulp is very high quality because we harvest it in-water. Any unsold pulp is converted into biochar, which can be used in green concrete and other sustainable building materials, locking the carbon away for hundreds to thousands of years.
“As far as we know, we are the only seaweed farming business from any seaweed species that can take a problematic seaweed bloom and preserve its freshness year-round in our unique Algaeponix paddocks.”
— John Auckland, CEO and Co-Founder

✔ Zero Waste to Landfill – Turn seaweed from a burden into a valuable resource.
Our Mission
A regional crisis into a global climate solution
Every year, millions of tonnes of Sargassum swamp the Caribbean, damaging tourism, killing marine life, and releasing methane as it rots. Where others see a problem, we see a resource: a low-impact, floating seaweed. Rather than relying on costly beach cleanups, we offer a proactive, tech-enabled solution, which supports expanded valorisation efforts.
We mitigate climate change in several ways by working with Sargassum: By intercepting Sargassum before it rots, we prevent methane emissions, one of the most potent drivers of climate change.
Any unused pulp is converted into biochar through our partners, securely locking away carbon for hundreds to thousands of years. And when transformed into biofuels or bioplastics, our Sargassum feedstock helps replace fossil fuels with renewable and circular alternatives.
