Welcome to the world of seaweed packaging!

LET'S DIVE IN

WHO MADE THIS?

We're Sway.
Nice to meet you!

Sway is a team of material scientists, designers, ocean lovers, and compost enthusiasts creating and scaling seaweed packaging — starting with bags for shipping and shopping. Get to know us!

Founded in 2020 and operating from the California Bay Area, our company is truly thrilled that Sway packaging is out in the wild. It's been quite the journey to get here!

We believe in a future where everyday materials can replenish the planet, from sea to soil — and so do our partners.

WHAT IS THIS?

The world's first scalable flexible film made with seaweed.

You're among the very first to experience this totally new packaging — and your feedback is super valuable as we continue to improve it.

WHY SEAWEED?

Seaweed helps replenish the planet.

This marine crop is abundant in natural polymers, the building blocks of Sway materials. When compared to common renewable packaging inputs like corn, potato, or sugarcane, the benefits of seaweed go above and beyond.

Seaweed thrives off sunlight and sea water, requiring little to no inputs — unlike terrestrial crops, farmed through systems of industrial agriculture. It’s fast-growing, space-efficient, and grown around the world.

Plus, seaweed creates regenerative impact (giving back more than it takes): increasing habitat for marine life, boosting biodiversity, and mitigating climate change impacts like ocean acidification and erosion. New science is proving that seaweed farming even sequesters carbon!

Hear from Sway Co-Founder & CEO Julia how seaweed became our hero ingredient.

HOW TO DISPOSE

Compost this bag!

Sway packaging is home and industrial compostable! We certify our materials through TUV Austria, the global gold standard.

Toss this bag in your backyard pile, countertop composter, or green bin — whatever composting method works for you. With the right heat, moisture, and microbes, this bag will fully decompose into healthy soil within 6 months.

Tips for success:
• If your bag has an adhesive strip, cut off before composting.
• If you compost industrially, check your local guidelines first.
• For faster decomposition, cut your bag into smaller pieces!

Note: This bag is not recyclable. When compost isn’t available, please dispose in trash. In landfill, it will break down like a piece of fruit.

 

FAQs

What is this bag made from?
Seaweed, plants, and compostable polymers. The material is majority biobased, and always improving. It's the first of its kind to be produced at scale, thanks to our incredible scientists and manufacturing partners achieving the previously unthinkable!
What does it decompose into?
Per TÜV Austria certification, our materials compost safely into carbon dioxide, water, inorganic compounds, and biomass. No microplastics, distinguishable remnants, or toxic residues left behind.
Will it decompose anywhere?
Sway packaging is designed for compost, where it breaks down with the help of heat, moisture, and microbes. Throwing it out in nature won't create the same magical decomposition formula — please don't litter.
How fast does it break down?
Per TÜV Austria certification, our materials break down within 6 months (and often less) in healthy compost environments. The same bag made from plastic would take 800 years to break down – into microplastics!
 
We'd love to see your composting results. Place your Sway bag in your home compost, snap photos along the way, and share how it breaks down through our feedback survey.
How can I make it break down even faster?
The smaller the piece of material, the easier microbes can break it down. To accelerate decomposition, cut your Sway bag into small pieces before placing in the compost.
What if I don't compost?
You might have more options than you think! Municipal programs, farm drop-offs, and private services are widely available. Search "compost service near me" to find local options. Or if you're curious about starting a home compost practice, check out Sway's quick guide.
 
This material is not recyclable — when compost isn’t an option, toss it in the waste bin. Even when Sway bags aren't composted, this material has already made an impact by reducing petroleum and uplifting renewable and regenerative ingredients, like seaweed! That's half the equation.🔎

Pretty neat, right?

We think so too — and we're keen to hear your honest feedback from your experience with our material. This will help us improve seaweed packaging more quickly!
