Seaweed Packaging

We make sustainable packaging from seaweed.

What’s the problem?

The plastic problem grows larger every day

91% of all plastic are not recycled. 5.5 trillion pieces of plastic are in the ocean today.

the perfect solution doesn’t exist, yet

Most existing bioplastics are input intensive, expensive, and don’t degrade naturally.

most plastic waste is packaging

Plastic wrappers and bags make up over 40% of the waste in our oceans.

why seaweed?

We’re big fans of regeneration.

Seaweed grows all year long without need for food, fertilizer, pesticides, land, or even fresh water. It also consumes crazy amounts of CO2, mitigates ocean acidity, exudes oxygen, and helps support biodiversity and healthy ecosystems!

The petroleum supply chain is “infrastructure for human life” because the extraction, refinement, and transformation of it creates only a net positive for human society but is deadly to the rest of earth. A seaweed supply chain creates “infrastructure for all of life” because it creates a net positive for the all of earth, humans included.

A Material of the Future

Packaging material makes up the bulk of single-use plastic pollution, but no perfect solution yet exists. We talked to experts in material engineering, marine biology and aquaculture to learn whether seaweed could be an answer to the plastic problem.


Frequently Asked Questions

What is Sway working on?

We’re currently developing a material that can beat traditional plastics, and researching methods for scaling this system. Unlike other alternatives to plastic, Sway products are derived from regenerative crops, actively improve ecosystems, and don’t require industrial facilities to degrade.

Why are we so interested in flexible plastic packaging?

Bags, pouches, wrappers, and films made from LDPE and Polypropylene are inexpensive and lightweight, making them a convenient packaging solution. No alternative yet matches the performance of traditional plastics while also remaining marine safe.
