Growing the Future: Scaling White Biotech to Outperform Fossil Plastics with Jeroen van Rotterdam

About this episode

Join Jeroen van Rotterdam, Co-Founder and CEO of Foamlab, for a deep dive into the industrial transition from extracted synthetic foams to bio-fabricated materials grown by nature. Every year, millions of tons of fossil-based plastic foams are manufactured for packaging, insulation, textiles, and automotive components—materials that generate persistent microplastic pollution and are virtually impossible to recycle economically. Jeroen explains why sustainability shouldn't be a trade-off, how white biotechnology yields materials with mechanical properties superior to petrochemical plastics, and how AI-driven bio-process optimization is accelerating the transition from laboratory Petri dishes to pilot-plant production scale.

🎯 Insights You’ll Learn:

The White Biotech Imperative: Why replacing non-degradable polystyrene and polyurethane requires shifting from petroleum extraction to industrial fermentation using microorganisms.

Bacterial Nanocellulose Platform: How bacteria consume simple sugars to synthesize high-purity cellulose networks that can be tuned into soft sponges, flexible textiles, or rigid load-bearing structural foams.

AI-Accelerated Biomaterial Engineering: Utilizing artificial intelligence and neural predictive models to optimize fermentation parameters, strain performance, and structural foam density in days rather than years.

Overcoming the Biotech Scale-Up Bottleneck: Lessons from raising €3 million in growth capital to build a pilot manufacturing plant, transition out of the lab, and navigate high-yield bioreactor engineering.

Lessons from Enterprise Tech to Deep-Tech Biotech: How Jeroen’s executive leadership experience at Citrix, Dell/EMC, and enterprise software startups informs his pragmatic commercial approach to unit economics and beachhead market selection.

🌍 Why This Matters:

Fossil-based foams like expanded polystyrene (Styrofoam) represent a $29 billion global market built on materials that persist in ecosystems for centuries. Merely tweaking traditional plastic formulations is no longer enough; industrial manufacturing requires a fundamental materials reset. Jeroen van Rotterdam and the team at Foamlab—a TU Delft spin-off—are proving that biology can cultivate materials that meet or exceed synthetic performance specs without environmental liabilities. By leveraging white biotech, automated fermentation tuning, and strategic pilot scale-ups, Foamlab provides a clear blueprint for turning greenhouse-intensive supply chains into circular, bio-based loops.

👤 Expert Background:

Former Executive Vice President of Engineering, Cloud, and Security at Citrix, and former executive at Dell/EMC.

Serial Tech Entrepreneur & Angel Investor, who previously founded X-Hive (acquired by EMC) and actively supports deep-tech and sustainable materials startups.

🎙️ Hosted by Gary Fowler, CEO of GSD Venture Studios — global AI entrepreneur, investor, and innovation leader spotlighting founders navigating the realities of building in the AI era.

💡 Perfect For:

Biotech investors, circular economy directors, materials science researchers, industrial packaging architects, automotive/aerospace supply chain leads, and deep-tech founders navigating pilot facility scale-ups.

🚀 Timely Topic:

As international regulations tighten around single-use plastics and microplastic pollution, the competitive edge belongs to companies that can supply high-performing, bio-fabricated alternatives at industrial scale. Jeroen van Rotterdam is sharing the exact operational and technological framework driving this shift in 2026.
