Real-World Sustainable Substitutes: The 11 Best Replacing Plastic Materials Podcasts With Scalable Alternatives
Let's go!
As plastic pollution accelerates alongside climate change, innovators are racing to replace petroleum-based materials with scalable, climate-positive alternatives. In this live episode from the 2026 San Francisco Climate Week, Dylan Garrett speaks with Julia Marsh, CEO and co-founder of Sway, Molly Morse, CEO at Mango Materials, and Ryan Starling, Design Director at frog Design, about how seaweed-based polymers and methane-derived bioplastics could transform the future of packaging and consumer products. They explore why sustainable materials must work within existing manufacturing infrastructure, how rigorous life cycle analysis helps win over brands and buyers, and why nature’s own materials often outperform engineered alternatives. The conversation also examines supply chain resistance, composting policy barriers, and the importance of designing climate solutions that align environmental impact with economic incentives and real-world adoption.
