Sway offers home-compostable replacements for thin-film plastic packaging derived from seaweed. We envision a future where every bag, pouch, and wrapper can help replenish ocean ecosystems and reduce plastic pollution, while simultaneously contributing to the sequestration of tons of carbon, supporting coastal livelihoods, and creating healthy soil in your own backyard after use. A material that gives more than it takes. That's what we're building at Sway — the material and cultural dimensions of a plastic-free future.
The company was co-founded by Julia Marsh, Matt Mayes, and Leland Maschmeyer and is headquartered in Oakland, California, United States.
