To tackle the climate crisis, we need radical action and bold ideas. Those advocating and delivering green solutions, lowering humanity's impact on the planet, are our champions. The podcast “Rooted in Change” interviews European cleantech protagonists about their solutions. Guests share ideas on how to accelerate change and deliver meaningful global impact.
Thanks to AI, finding new enzymes is almost easy. But running them continuously at an industrial scale? That’s the real challenge and exactly what Biozeroc is tackling. They build the missing layer to keep enzymes alive and there and enable a continuous processing infrastructure. By plugging their continuous reactors directly into existing plants, they completely take enzyme lifetime out of process design. Liv shares in this episode her entrepreneurial journey, how her upbringing in Northern Sweden has ingrained a deep admiration for nature and the one thing that keeps her going. We recorded this special episode live at The Drop, featuring some great questions from the audience.

Estelle Clerc - CellX
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 CellX replaces these outdated practices by capturing and scaling unique bacterial consortia to break down these pollutants biologically.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.

Lukas Porz - Illutherm
Decarbonizing high-temperature industrial heating remains one of the hardest challenges in the energy transition, often requiring massive amounts of fossil fuels. The industry continues to rely on traditional kilns that waste huge amounts of energy heating the surrounding air and walls, until now. Illutherm replaces these outdated, carbon-heavy methods by introducing a breakthrough digital solution: heating with blue LED light. By generating heat directly inside the material itself, this highly precise technology can bring materials from 0 to over 1000°C in just a matter of seconds, maximizing efficiency and enabling completely CO2-neutral industrial processing. Lukas talks about how he first came across this groundbreaking idea, how fast the company has managed to scale and Illutherm's ambitious plans going forward to revolutionize industrial heat.
