A Sustainable Supercrop

The seaweed advantage

Ecosystem service provider

Seaweed filters water, absorbing excess nutrients, sequestering carbon, and fostering marine biodiversity.

Regenerative, low input crop

Seaweed grows rapidly, thrives on minimal resources, and naturally replenishes nutrients for sustainable growth.

Natural/biodegradable

Seaweed decomposes safely, reducing waste and fostering eco-friendly alternatives to petroleum-based plastic.

Process/Lifecycle

We start with seaweed—and end with a cleaner planet

  • Step 1

    Seaweed harvesting

    Seaweed is collected from seaweed farms globally, which fosters renewable resources and enhances ecosystem resilience.

  • Step 2

    Bioplastic processing

    Seaweed is processed and compounded to create sustainable, biodegradable bioplastics. Depending on the product, the polymer is either spun or pelletized

  • Step 3

    Biodegradation

    At the end of the product lifespan, microorganisms break down seaweed bioplastic into simpler, non-toxic compounds that safely rejoin the ecosystem.

Not All Polymers Are Created Equal

We’re different.
