Using the
power of the ocean
to heal the ocean

We harness the natural properties of sustainably sourced seaweed, to create the best replacements for plastics. After use, our biodegradable products return to the soil to nourish it.

Goodbye Plastic
Hello SEAWEED

Our seaweed-based, natural polymer films are engineered to mimic all the great benefits of plastic, without any of the nasty bits. With constant innovation we produce the strongest, thinnest, most durable, 100% natural, biodegradable film.
