Leading the Circular Economy Revolution with Sargassum 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 achieved through our SeaClear and Sea*** Solutions, which allow us to catch, cultivate and harvest Sargassum. Creating a valorisation pathway whilst protecting vital Caribbean coastlines.
Our Services.
From coastal protection to industry feedstock
Sargassum Management
We intercept Sargassum at sea with our SeaClear system, stopping harmful blooms before they reach coastlines and protecting fragile ecosystems.
The seaweed is intercepted behind deflection barriers and then stored in the water 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
Under license from partners Carbonwave, we process fresh Sargassum into natural biostimulants that boost crop growth and resilience 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 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
Sargassum Management.
A cost-effective solution for Caribbean Hotels and Governments
Sargassum threatens guest experience, drives up costs, and harms marine ecosystems and local communities throughout the Caribbean. Traditional methods, manual removal and landfill disposal are ineffective, costly, and environmentally harmful. Seafields offers a cost-effective way to keep your beaches free of Sargassum using our in-water technology.
Manufacturers.
Sustainable inputs with verifiable impact
Today’s manufacturers need more than just sustainable sourcing, you need hard data, traceable supply chains, and a credible story that resonates with regulators and customers alike. Seafields provides Sargassum biomass as a feedstock designed to meet those needs.
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.
