Earthfeed: From Soil to Shelf

In this episode of the Earth Feed Podcast: From Soil to Shelf, host Kelly Williams and guest Diana Thomas, Sustainability Director at Biologiq, explore the complexities of composting, sustainable packaging, and the intersection of food waste with packaging choices. Diana draws on her experience in sustainability and compostable certification to debunk myths and provide insights into what works in compost piles. Key topics discussed include: Food Waste and Composting: Diana highlights that food waste is a significant contributor to global carbon emissions, underscoring the importance of effective composting systems and packaging designed for biodegradability. Paper vs. Plastics Debate: They discuss the misconception that paper is universally better than plastics. Diana explains the environmental trade-offs, including the energy and water intensity of paper production and its challenges in composting. The conversation emphasizes that combining paper and bioplastics could create more sustainable solutions. Bioplastics and Efficiency: Diana shares insights into bioplastics' benefits, such as reduced chemical additives, efficient decomposition in advanced composting systems, and lower environmental impact compared to fossil-based plastics. Challenges in Composting Infrastructure: The limited capacity of industrial composting facilities to process packaging materials is a bottleneck. The conversation advocates for systemic changes, such as policy reform and community-led composting initiatives, to support better waste management. Education and Greenwashing: Diana and Kelly stress the importance of educating consumers on sustainable options and combatting greenwashing practices. They encourage transparency and accountability in sustainability claims. The episode concludes on an optimistic note, emphasizing the growing cultural shift toward sustainability and the importance of collaborative efforts to advance composting infrastructure and regenerative practices. This engaging discussion offers practical insights for consumers, businesses, and policymakers aiming to tackle packaging and waste challenges.

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.
