Replenishing life at every step of the supply chain.

Sway uses the principles of the circular economy to design not only our products, but our entire supply chain to restore social and natural systems harmed by climate change and pollution.


Regeneration goes beyond the call for sustainability, encouraging us to design not simply to avoid harm, but to restore and replenish our aching planet.

While traditional plastics contribute to climate change at every step of their toxic existence, Sway materials are made with process in mind. We strive to undo the harms of plastic pollution everywhere, from the ocean to your backyard.

Sourcing Strategy

Rather than viewing the ocean as a victim, we believe solutions for some of our biggest climate challenges have been underwater all along. Our sourcing impact is reflected through 3 primary categories:

Cultivation Methods

Sway sources responsibly cultivated, ocean-farmed seaweed grown in harmony with the ocean. We make a couple exceptions for certain types of seaweed, like sargassum – an invasive equatorial species that Sway is exploring as an underutilized resource through the Puerto Rico Studio project. We require all prospective suppliers to report data including certifications, ecosystem impacts over time, processing footprint, and much more.


Global & Regional Diversity

Sway uses a diverse set of red and brown seaweeds from around the world as the base of our packaging technology. Seaweed is naturally rich in polymers (agar, alginate, and carrageenan), all of which Sway is exploring in our formulations. With diversity as a top priority, we help support the positive impacts of expanded seaweed cultivation while avoiding over-reliance on any one region or species.


Coastal Community Impact

Sway works exclusively with suppliers who provide dignified employment to farmers, meaning fair wages and good treatment. We are hard at work to support and help scale up suppliers for whom impact is the number one priority, such as supporting the transition to climate-resilient coastal economies with lobster fishermen in Maine, Indigenous communities in Brazil and Chile, and tourism-reliant communities in the Caribbean. And that’s just the beginning!

Partner Farms

Sway sources seaweed around the world, from commercial suppliers to small-scale farmers in emerging blue economy zones. Meet a few of our fantastic partners, each of which exemplifies the great diversity of social and environmental impacts seaweed can make.

Impact Ecosystem

Sway works in tandem with on-the-ground impact partners to ensure that as our product scales, so does our impact. 


Seaweed FAQ

Why seaweed?
Seaweed is a renewable marine crop plentiful in natural polymers, the building blocks of Sway’s material portfolio. When compared to common renewable packaging inputs like corn, potato, or sugarcane, the benefits of seaweed truly go above and beyond!

Seaweed thrives off sunlight and sea water, requiring very few inputs – unlike terrestrial crops farmed through systems of conventional agriculture. It’s abundant, fast-growing, space-efficient, and available on nearly every coastline in the world. Seaweed can also generate a whole lot of good as it grows: increasing habitat for marine life, boosting biodiversity, and mitigating climate change impacts like ocean acidification and erosion. Plus, new science suggests that seaweed can sequester substantial amounts of carbon!
What is regenerative ocean farming?
Regenerative ocean farming is a climate-friendly model of aquaculture where seaweed (and/or shellfish) are grown in a way that requires no freshwater, feed, or fertilizer — fueled simply by sun and ocean nutrients. This farming model can benefit coastal ecosystems and communities by increasing food security, creating jobs, improving water quality, protecting coastlines, and providing a range of additional ecosystem services!

We are excited to see these positive impacts taking place in real-time through Sway’s seaweed sourcing partners, like Atlantic Sea Farms, who offer kelp farming opportunities to local fishing communities as a way to diversify incomes, adapt to climate change, and continue working at sea sustainably.
Does Sway harvest the seaweed?
No. We source seaweed from a global network of trusted farmers and processors.
What kind of seaweed does Sway use?
Core to our sustainability strategy, Sway works with responsibly ocean-farmed macroalgae and extracts from around the world. We prioritize diversification in our sourcing to avoid over-reliance on any one region or species, and support the positive impacts of expanded seaweed cultivation around the globe!

We are also actively exploring the use of sargassum, an invasive species and untapped resource, through the Puerto Rico Studio project led by Newlab and Invest Puerto Rico.
Is there enough seaweed in the world?
Seaweed cultivation is an established and growing industry. Beyond its obvious use in food, seaweed is used as a binding ingredient in everyday items like cosmetics and pharmaceuticals. There could be seaweed in your toothpaste, shampoo, lotion, donut glaze, and even the pill caps for your daily vitamins.

Thanks to increased demand, annual seaweed cultivation has increased to over 35 million metric tons worldwide – more than doubling in the last decade!
How does Sway support the seaweed industry?
Sway works closely with partner farms and processors to contribute to new research around the impacts of seaweed farming including biodiversity, water quality, carbon sequestration, and social impact. Through these partnerships, we ensure the benefits of seaweed farming are prioritized as demand rises. Read more about our vision for a thriving seaweed economy on Grist.
