If you’re in San Francisco, join 5 Gyres and The Carbonauts for a live panel discussion, ‘Better Alternatives to Plastic – Now!’ on May 28 to learn about the role alternative materials can play in driving solutions.
About the Event
The Carbonauts and 5 Gyres invite you for an exclusive Sustainability Session and Panel featuring top leaders in the sustainable materials space.
Plastic waste can now be found in every corner of the globe. Plastics contaminate the environment, entangle countless marine and land animals, and are inextricably linked to the climate crisis since plastic production (especially single-use plastics) contributes significantly to global emissions.
Microplastics (plastic particles one μm to five mm in size) contaminate our food and water, accumulating in our bodies, posing a serious risk to our health. Unfortunately, even with the publication of alarming studies and reports on this issue, plastic production continues to increase. Tackling the climate crisis must include finding solutions to the accumulation of plastic waste in our environment and advocating for sustainable alternatives to single-use plastics.
5 Gyres uses science-driven research to lead the way in driving upstream solutions to the plastic crisis through education, advocacy, and community building.
We’ll hear from some of today’s pioneers leading the way in reducing plastic pollution and developing sustainable alternatives:
Kathleen Egan (Moderator) – A sustainability leader and 5 Gyres Board Member, Kathleen is dedicated to advancing solutions to plastic pollution through research, advocacy, and community engagement.
Helen Yang – CEO & Co-Founder of Clement Packaging, Helen is pioneering biodegradable and compostable packaging solutions to replace single-use plastics.
John Felts – CEO & Co-Founder of Cruz Foam, John is an innovator in eco-friendly, bio-based foam packaging, transforming waste materials into sustainable alternatives.
Jonathan Taylor – A polymer scientist and 5 Gyres Board Member, Jonathan specializes in material innovation and policy advocacy to combat plastic pollution.
Julia Marsh – CEO & Co-Founder of Sway, Julia is revolutionizing seaweed-based packaging that is regenerative, scalable, and designed to replace plastic films.
Join for complimentary, sustainable drinks, an in-depth and informative discussion, plus great conversations with your fellow sustainability peeps!

Our world is overwhelmed by single-use plastic packaging and products, and it’s having devastating consequences on our climate, communities, and health. But what if all those items weren’t made of toxic, fossil fuel-based plastic? What if they were made from regenerative materials like mushrooms or seaweed?
Join us Thursday, August 25, 2022, as we sit down with three companies providing innovative technologies to replace single-use plastics with renewable, compostable, and eco-friendly alternatives—Ecovative, LOLIWARE, and Sway. Unlike so-called “bio-based plastics,” seaweed and mushroom materials do not require harmful plasticizing chemicals to work, and are truly zero waste and regenerative alternatives. Panelists will include Julia Marsh, Co-Founder and CEO of Sway, Meghan Olson, Director of Mushroom® Packaging at Ecovative, and Dr. Victoria Piunova, Chief Technology Officer at LOLIWARE. The panel will be moderated by Julia Cohen, Managing Director of Plastic Pollution Coalition.
