From Waste to Wealth: How Urban Mining Can Solve the Critical Metals Shortage Artwork

Resilient Supply Chain — How Leaders Keep Business Moving

Resilient Supply Chain is for supply chain, operations, procurement and technology leaders who need practical ways to manage disruption, reduce risk and keep business moving.

Each Monday, technology and sustainability analyst, keynote speaker and former SAP Global VP Tom Raftery speaks with the executives, operators, founders and innovators redesigning how goods, information and decisions move through global supply chains.

These are candid conversations about what works in practice—not polished PR narratives or vague predictions. Guests explain how they are responding to supplier failures, geopolitical shocks, volatile costs, capacity constraints, changing regulations and rising pressure to improve both performance and sustainability.

The podcast examines:
Faster planning and decision-making under uncertainty
Supplier risk, sourcing strategy and business continuity
AI, automation, visibility and operational intelligence
Warehousing, logistics and fulfilment performance
Scope 3 emissions, circularity and responsible sourcing
The systems, incentives and organisational changes needed to turn data into action

The central question is simple: what helps a supply chain withstand disruption, adapt quickly and continue serving the business?

New episodes are published every Monday at 7am CET. Resilient Supply Chain+ subscribers also receive bonus analysis, highlights and briefings on emerging industry trends.

Follow Resilient Supply Chain for practical lessons from the people solving real operational problems—and building supply chains that perform when conditions do not go to plan.

From Waste to Wealth: How Urban Mining Can Solve the Critical Metals Shortage

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.
