Earthfeed: From Soil to Shelf

In this podcast episode, Kelly Williams from Earthfirst and Rob Cotton from PepsiCo delve into the challenges and innovations in sustainable packaging. They discuss PepsiCo's journey in developing compostable and environmentally friendly packaging, starting from their first industrial compostable bag for SunChips in 2009. They highlight the technical difficulties of creating compostable films that meet PepsiCo’s rigorous moisture and oxygen barrier requirements, with Rob emphasizing that achieving high-performance, compostable packaging has been possible only through recent innovations in polymers and coatings. A significant theme in their conversation is the industry's need for collaboration, where PepsiCo shares technology and encourages small and medium brands to adopt sustainable packaging. Rob discusses the broader impacts of environmental legislation, such as the UN Plastics Treaty and Extended Producer Responsibility taxes, on pushing companies toward sustainable packaging. He also mentions PepsiCo’s efforts to make these new materials accessible by partnering with suppliers and converters. The episode ultimately encourages brands of all sizes to embrace sustainable packaging, assuring smaller companies that these advanced materials have been extensively tested and optimized for performance and environmental safety. Both hosts emphasize the importance of working together to combat plastic pollution and promote sustainability, underscoring a commitment to reducing environmental impact on a global scale.

In this episode of "Earth Feed: From Soil to Shelf," Kelly Williams hosts Dr. Evan White, an assistant research scientist and director of the Biosynetic Laboratory at the University of Georgia's New Materials Institute. They dive deep into the challenges and opportunities of transitioning to compostable packaging. The conversation explores the science behind compostable materials, the impact of various packaging chemistries, and how consumer behaviors influence sustainable waste management. Dr. White shares insights from a recent study funded by the Walmart Foundation on composting infrastructure, addressing the importance of scaling solutions from small cities to larger ones. The discussion also emphasizes the role of public-private partnerships in fostering innovation and sustainability in packaging.
