Seaweed
The Packaging You’re Holding is Groundbreaking!
Sway Polybags
Made with seaweed, plants, and home compostable polymers.
HOW TO DISPOSE
This bag is home and industrially compostable (certification pending). This bag is not recyclable. Individuals who do not have access to composting should landfill these bags.
Sway Retail Boxes
100% recycled paper fiber box with compostable seaweed-based window.
HOW TO DISPOSE
This box is curbside recyclable. Put it in your recycling bin and the seaweed-based window will be screened out during the repulping process.
The seaweed-based window is home-compostable, meaning it will break down into a healthy soil amendment. Simply remove the window from the box, throw the window in home or industrial compost, and curbside recycle the box.

Seaweed as a Packaging Input
Why It Matters
Seaweed is an emerging packaging input with big regenerative potential. Most biobased packaging inputs such as corn, sugarcane, potatoes, or wood chips, degrade soils, threaten biodiversity, require high volumes of freshwater, result in nitrogen and phosphorus runoff, or rely heavily on fossil fuels for production.
Seaweed is different. Seaweed cultivation requires no land, fresh water, or fertilizers to grow, while actually improving ocean health, strengthening marine life and biodiversity, and improving the livelihoods of the coastal communities.
Seaweed holds incredible promise, and Sway is paving the path towards making this material widely available long-term.
The packaging you’re holding is an early step in achieving this vision!
Sway Polybag Compostability
Learn More
The Sway Polybag is pending the TUV Austria Home and Industrial Compost certification. The testing is actively in progress and expected to be completed by mid-2025.
We are confident that the Sway Polybag will pass the TUV Austria standards due to previous success with home compost testing (ISO 20200) and field partner testing in industrial composting sites. Until we have the certification, we will be comfortable with end users composting the Sway Polybags at home.
Once we can print the certification on the bags, industrial composting will become an additional end-of-life solution.
EcoEnclose is thrilled to partner with Sway, a biomaterial innovation company dedicated to moving beyond sustainability towards regeneration.
Sway seeks to extend the ocean's inherent generosity by pairing seaweed's benevolent qualities with advanced materials science. They are designing next-generation replacements for plastic that replenish seas, soils, and coastal communities. The flexible films they are developing are the real deal: Certified 100% Biobased, home compostable, and scalable.
