In this episode of Mulch Matters, we are joined by Dr. Carol Miles from Washington State University, for a compelling conversation about her recent trip to China to attend the International Strawberry Symposium. Our discussion offers a fascinating window into the contrasts and connections between Chinese and U.S. agricultural practices, particularly around strawberry production and plastic mulch use.

Carol reflects on the incredible technological leap she observed in Chinese greenhouses, where high-tech, hydroponic tabletop systems are now used in showcase facilities. But she also shares her experience visiting local farms after the symposium, where strawberry production looked much more traditional—though still impressive. One of the most striking takeaways was how small-scale farms in China can remain highly profitable and deeply integrated into the community, offering lessons in sustainability and land stewardship that may be overlooked in the U.S.

This conversation is not only an agricultural deep-dive—it’s a thoughtful reflection on culture, economy, and the future of food systems. Whether you’re a grower, researcher, or simply curious about how other countries are innovating in agriculture, this episode will leave you with fresh perspectives and new questions to consider.

In this episode we have an engaging conversation with Kevin DeWhitt, the founder of PDO Technology, about the pressing issue of plastic waste management in agriculture. As the world grapples with plastic pollution, innovative solutions are needed to tackle this environmental challenge. Kevin brings his expertise in pyrolysis, a cutting-edge process that breaks down plastic mulch waste and repurposes it into valuable resources. This process not only reduces landfill dependency but also supports a circular economy, promoting sustainability in agricultural practices.

During our discussion, Kevin explains the intricate workings of PDO Technology and how it efficiently processes agricultural plastics, even when they are contaminated with soil or organic matter. Unlike conventional recycling methods that struggle with dirty plastics, PDO’s technology thrives in handling the toughest waste, ensuring that no plastic is left behind. He also highlights the importance of collaboration with farmers, universities, and industry leaders to create a comprehensive approach to waste management.

The conversation delves into the challenges and breakthroughs in plastic recycling, from logistical hurdles in waste collection to technological advancements that make recycling more feasible. Kevin shares insights into the evolving landscape of sustainable agriculture and how innovative solutions are shaping the future. His passion for sustainability is evident as he discusses the potential for widespread adoption of these technologies, paving the way for a more responsible and efficient system for handling plastic waste.

As the world shifts towards more sustainable practices, it is crucial to explore viable alternatives for managing agricultural plastics. This episode provides valuable insights into the role of science, technology, and collaboration in driving meaningful change. Listeners who are interested in cutting-edge recycling technologies, sustainable farming, or practical solutions for plastic waste management will find this discussion both informative and inspiring.
