A new source of sustainable feedstock

Today’s manufacturers need more than sustainable sourcing. They need reliable supply, traceability and the data to back it up.

Seafields transforms abundant Sargassum into a consistent, traceable feedstock for the next generation of sustainable products.

  • Seafields Pilot operations

    Granular impact data

    Our smart AlgaePonix monitor Sargassum health, biomass and environmental conditions, creating traceable data to support lifecycle assessments and environmental reporting.

  • Beached Sargassum

    Stronger green premium narrative

    Turn a coastal problem into a productive resource. Using Sargassum creates a compelling sustainability story around cleaner coastlines, ecosystem protection and more productive use of natural biomass.

  • Seafields team and pilot paddock

    Shorter, smarter supply chains

    Sargassum is intercepted, stabilised and preprocessed close to source, reducing unnecessary transport while preserving its value as an industrial feedstock.

    What Seafields delivers

    Reliable, traceable Sargassum feedstock for biostimulants, biochar, pulp, biomaterials and other emerging markets.

Product Pathways

Our proprietary AlgaePonix paddocks keep Sargassum alive and stabilised, transforming an abundant but unpredictable ocean biomass into a reliable, traceable feedstock for industry.

From biostimulants and biochar to pulp and biomaterials, Sargassum has the potential to replace conventional inputs across a growing range of products, creating value from a resource that is currently largely treated as waste.

And nothing needs to go to waste: liquid fractions can supply biostimulants, while the remaining solids can become pulp and biochar, including low-carbon additives for cement and concrete.
