PFAS has already made a number of appearances on this show, but safely eliminating these toxic "forever chemicals" and other micropollutants remains a massive challenge. Finding the exact microorganisms capable of degrading them is like finding a needle in the haystack, which is why the industry still heavily relies on costly, unsustainable disposal methods like incineration. CellX replaces these outdated practices by capturing and scaling unique bacterial consortia to break down these pollutants biologically.

Positioning themselves as a comprehensive biosolutions company rather than just a PFAS remediation startup, they use patented microtechnology to deploy these bacteria to treat both industrial wastewater and contaminated soils. Estelle joins the podcast to talk about how they managed to discover these rare bacterial degraders, the mechanics behind their biological treatment, and why the Zurich ecosystem provided the perfect foundation to spin off the company.
