Impact

A well-run seaweed farm regenerates the sea, energizes the coast and builds a new industry.

Farming seaweed regenerates the sea and the coast

Chile is one of the world’s largest seaweed producers, but almost all of its harvest comes from natural beds: variable quality, little traceability and pressure on the ecosystem. Farming is how to grow without depleting the beds, and Chile already has the know-how to do it.

  • Environmental regeneration

    A seaweed farm captures carbon, takes up nitrogen and phosphorus from the water and offers shelter and food to fish, invertebrates and seabirds. It needs no freshwater, fertilizer or arable land.

  • Coastal regeneration

    It gives small-scale fishers and coastal communities an alternative to wild harvesting, with training, quality seed and formal work at sea.

  • Economic regeneration

    Farmed seaweed comes with a known origin and consistent quality, which opens markets that pay more than for wild-harvested seaweed and diversifies the coastal economy.

The gaps we help close

Kelp farming in Chile is still mostly at pilot scale. Closing these gaps is what turns pilots into an industry.

  1. 01

    Standardized seed

    Hatcheries with repeatable protocols, so that yield at sea does not depend on chance.

  2. 02

    Climate change adaptation

    Gametophyte banks and selection of local strains to conserve genetic diversity and face warmer seas.

  3. 03

    Technified seeding and harvest

    Direct machine seeding, line and mooring design, and mechanized harvest to produce at scale.

  4. 04

    Added value

    Products and processes that turn biomass into higher-value ingredients, from biostimulants to biomaterials.
