Let’s be honest. Plastic is on the out. It’s overflowing out of landfills and washing up on our shores. While plastic is a super useful material that has helped build the modern world. The problem is, it often outlives its intended use by thousands of years.

Enter Julia Marsh and Matt Mayes, co-founders of Sway Seaweed Packaging. Growing up with a deep connection to the ocean near Monterey, California, Julia has always marveled at the generosity and abundance of the ocean.

Seaweed is a resource that requires no arable land and freshwater to produce. It grows quickly, sequesters carbon, and is strong and flexible. Recognizing its unique properties, Julia and Matt have developed a biopolymer that can serve as a substitute for plastic packaging.

Their innovation is already used to package fashion products, offering a more sustainable alternative for the clear plastic windows that let you see inside the pack. The best part? The materials are 100% compostable, even in home compost settings, so they only last as long as they’re needed and then go back to nourishing the Earth.
