We transform the ocean’s abundant seaweed, Sargassum, into a powerful climate solution.

From protecting Caribbean beaches with our SeaClear and SeaGrow farms to scaling sustainable biomass production in the open ocean, we’re building a zero-waste, nature-based industry that removes gigatonnes of CO₂ whilst valorising Sargassum to create bio-based products for a regenerative future.

Seafields aquafarms will employ thousands of people in economically deprived areas, creating good jobs year round in an industry that is expected to grow exponentially.

13

Seafields will remove carbon from the atmosphere on a large scale, working with dozens of other organisations in the CDR (Carbon Dioxide Removal) sector to achieve the goal of 'net zero' and beyond.

Seafields will grow and harvest Sargassum for products that replace fossil fuels, including bioplastics, fertilizers and emulsifiers.

No single company can solve the climate crisis alone. Seafields is part of a powerful network of private and public sector partners sharing experiences and helping to raise awareness of the potential of marine biomass.

Seafields is a science-based company. With the goal of developing the largest aquafarm in the world, we will pave the way for similar sustainable infrastructure projects.

Seafields' aqua farms serve as nurseries for fish and other marine life, helping to create new ecosystems in the open ocean.

Heal the planet working with the oceans.

We are the first company to successfully domesticate pelagic Sargassum, the free-floating seaweed capable of thriving in the open ocean. Our proprietary Algeaponix systems enable the year-round harvesting and cultivation of this fast-growing, carbon-hungry seaweed, turning it into a consistent, scalable feedstock for sustainable industries.

From biostimulants and emulsifiers to biochar and vegan leather, Sargassum’s applications are vast. By supplying companies creating planet-positive materials, we’re replacing fossil-fuel-based inputs and enabling new bio-based value chains.

Reducing our carbon output is only fixing one part of the global problem facing humanity. The only way to not only reach net zero but regenerate our life-giving ecosystems is to remove – or sequester – some of the 50 gigatonnes of greenhouse gases that we emit each year.
