What if I told you that most of the platinum and palladium in old diesel vehicles ends up lost or landfilled, even though these are some of the world’s most critical and valuable materials?

In this episode of the Sustainable Supply Chain podcast, I sit down with Don Weatherbee, CEO of Regenx, to explore how his company is turning waste into opportunity. Regenx has developed a low-energy, chemical-based process to recover platinum and palladium from diesel catalytic converters, materials that traditional smelters have largely ignored.

We discuss why diesel converters are harder to recycle than petrol ones, how their process avoids the high energy costs of smelting, and why circular supply chains like this are vital for reducing dependency on mining in places like South Africa and Russia.

Don shares insights on scaling urban mining, the importance of building local processing capacity, and the hidden supply chain of 27 million catalytic converters scrapped globally each year, most of which are never properly recycled.

If you care about circular economy strategies, critical raw material supply, or the future of sustainable manufacturing, this episode is for you.
