S2 Ep9: Can We Destroy Forever Chemicals? with Dr. Bruce Rittmann

In this episode of the Not Impossible Podcast, host and Not Impossible Labs founder Mick Ebeling sits down with Dr. Bruce Rittmann, one of the world’s most influential environmental engineers, to explore a growing global problem hiding in plain sight: forever chemicals.

Also known as PFAS, these man-made compounds are used in everyday products like non-stick cookware, waterproof clothing, and stain-resistant materials. They are designed to last, but that same durability means they do not naturally break down, allowing them to accumulate in water, food, and the human body.

Dr. Rittmann explains how microorganisms, often overlooked by humans, can become powerful partners in addressing this challenge. By delivering electrons in the right way and using catalytic materials like palladium, his team has developed a process that does more than filter pollution or move it elsewhere. It chemically transforms some of the most persistent contaminants on Earth into compounds that can finally be broken down safely.

Together, Mick and Dr. Rittmann unpack the science behind forever chemicals, the breakthrough moment that made this approach possible, and what it would take to scale this technology in real-world water treatment systems. From contaminated sites to drinking water facilities, this conversation explores how a problem once thought permanent may no longer be forever.

TOPICS COVERED

What forever chemicals are and why they are so difficult to break down
How PFAS ended up in everyday products and the environment
The role microorganisms play in transforming harmful pollutants
What scaling this technology looks like in real-world water treatment systems
