Circular Nutrition: Unlocking the Value of Upcycled Ingredients in Pet Food

To begin, Dr. D. Ocker shares her professional journey through academia, pet food research and development, human food innovation, and ingredient technology. Throughout her career, she has remained passionate about identifying opportunities to transform underutilized food resources into valuable nutritional ingredients. Next, Trent Small discusses his role at International Ingredients Corporation and explains how IIC evaluates emerging ingredient opportunities, assesses manufacturing feasibility, and develops partnerships across multiple animal nutrition sectors. As a result, listeners gain a better understanding of how ingredient innovation moves from concept to commercial application. (03:44 – 08:56) From there, the conversation shifts to defining circular nutrition and examining the growing role of upcycled ingredients in pet food. Specifically, Dr. D. Ocker explains how food-system co-products that are no longer suitable for human retail markets can be safely and effectively repurposed into functional pet food ingredients rather than entering waste streams. (09:49 – 15:12) To illustrate this concept, the panel reviews examples including dried cheese powders, bacon fat powders, dairy-derived ingredients, and other food-industry co-products. In many cases, ingredients may become unsuitable for retail sale due to packaging errors, labeling issues, or logistical challenges, yet they still retain significant nutritional value. (11:11 – 15:12) Furthermore, the speakers explore the sustainability benefits of circular nutrition. Dr. D. Ocker reviews the EPA Food Recovery Hierarchy and highlights how directing food-system co-products toward animal and pet nutrition helps maximize resource utilization. Consequently, fewer valuable resources are lost through lower-value applications such as composting or disposal. (13:34 – 16:05) In addition to sustainability considerations, the discussion addresses ingredient sourcing, safety, and regulatory compliance. The panel explains how suppliers and manufacturers collaborate through auditing programs, quality assurance processes, and traceability systems to ensure ingredient integrity throughout the supply chain. Therefore, pet food manufacturers can confidently incorporate alternative ingredient streams while maintaining quality and compliance standards. (17:08 – 19:41) The conversation then turns to the distinction between co-products and by-products, a topic that often generates confusion among consumers. While many consumers associate certain ingredients with lower quality, the speakers emphasize that numerous highly nutritious ingredients, including organ meats and specialty animal-derived ingredients, are frequently underutilized because of perception rather than nutritional value. As such, consumer education remains an important opportunity for the industry. (19:42 – 23:37) Innovation and Sustainability in the Future of Pet Food Building on this discussion, the panel explores emerging opportunities in companion animal nutrition. For example, specialized dairy-derived ingredients sourced from colostrum and casein-containing streams may offer new possibilities for functional pet food products and targeted nutritional solutions. (24:28 – 27:56) Meanwhile, sustainability reporting continues to play an increasingly important role across the pet food industry. The speakers review Scope 1, Scope 2, and Scope 3 emissions considerations and discuss why manufacturers are requesting more environmental data from suppliers than ever before. Ultimately, ingredient sourcing decisions can influence broader sustainability goals and corporate environmental initiatives. (27:57 – 34:43) Finally, the episode concludes with a broader conversation about responsible sourcing, ingredient transparency, innovation, and purpose-driven product development. The panel encourages nutritionists, formulators, and pet food professionals to remain open to unconventional ingredient opportunities and to continue exploring ways to improve resource utilization across the food system.
