Show Notes:

In this episode of Harvesting Wisdom, titled “Beyond the Bin: Denali’s Role in Reimagining Waste”, host Mike McMahon welcomes Margaret Wilson, General Manager of Denali Arizona, to explore the critical role of large-scale composting in building a circular, climate-smart future.

With decades of experience in engineering and military logistics, Margaret brings a unique perspective to her work at Denali. From converting food waste into compost and animal feed, to reclaiming cooking oil for biodiesel, Denali is reshaping the waste conversation—not just in Arizona, but nationwide.

You’ll hear about how Denali works with major municipalities like Phoenix, Goodyear, and Glendale, and collaborates with Walmart and other corporations to close the loop on food and organic waste. They discuss cutting-edge composting technology, VOC regulations, and how education and community behavior are pivotal to the success of sustainable systems.
