Sway Polybag

Made from seaweed, plants, and compostable polymers. The Sway Polybag is home and industrially compostable (certification pending). Learn more below.

Don’t compost? Consider starting, or find a nearby facility! Farm programs, community gardens, or private services may also be available locally.

This bag is not recyclable. When composting isn't available, put it in the trash – but rest assured, each Sway Polybag still creates a positive social and environmental impact. Seaweed improves ocean health and supports coastal communities!

Sway Retail Boxes

The clear window on these 100% recycled paper boxes is Certified 100% Biobased, made entirely from seaweed and plants!

Recycle the whole box, or peel off and compost the window for maximum circular benefits. The window is Certified Home & Industrial Compostable by TUV Austria.

In recycling systems, the seaweed window will be screened out during the repulping process. In a healthy compost, the seaweed window will break down into a nutrient-rich soil amendment.

Seaweed is an abundant, fast-growing, space-efficient marine crop that’s quickly gaining recognition for its ability to mimic plastic. When compared to common renewable packaging inputs like corn, potato, or sugarcane, the benefits of seaweed truly go above and beyond!

Seaweed thrives off just sunlight and sea water, requiring very few inputs – unlike resource-intensive terrestrial crops farmed through systems of industrial agriculture.

It’s also considered regenerative, creating positive impacts as it grows: increasing habitat for marine life, boosting biodiversity, and mitigating harmful climate change impacts like ocean acidification and erosion. New science shows that seaweed can even sequester substantial amounts of carbon!

The Sway Polybag is currently pending home and industrial compost certification by TUV Austria. While all Sway materials are designed to be compostable, certification takes time – testing is actively in progress, with results expected in 2025.

Successful lab and field testing gives us strong confidence that the Sway Polybag will pass certification with flying colors.

Until we receive official TUV certification, home composting the Sway Polybag is the best option. Better yet, you can play a role in Sway R&D by sharing feedback and photos on how the bag decomposed through Sway’s feedback form!

When Sway Polybags receive certification, industrial composting will become an additional end-of-life solution – and we will print the certification logo in a high-visibility area of the Sway Polybag to ensure the most possible bags are properly composted.

Thank you for playing a role and supporting next-generation materials as we bring them to market!
