Everybody agrees sustainable aviation fuel is essential for reducing aviation’s emissions. So why isn’t it already everywhere?

Former SkyNRG CEO Philippe Lacamp explains why the biggest challenge is no longer proving SAF works, but producing enough of it. We discuss investment, regulation and the enormous industrial effort required to build a new fuel industry.

The question now is whether we can produce enough SAF, fast enough.

Bart Langius explains why replacing fossil-based plastics is not just a chemistry challenge, but an industrial one. At Avantium, he is helping bring PEF, a polyester made from plant sugars, from pilot scale into the market. The conversation looks at Europe’s weakening petrochemical position and the real hurdles facing new materials: cost, scale, customer risk, and recycling systems. It is a practical look at what it takes to build a new materials category.

Olivier Rolland is a chemist turned sustainability strategist working at the intersection of biology, business, and climate impact. Over two decades, he has worked on bio-based materials, sustainable aviation fuel, and large-scale supply systems across companies like Michelin, Total, Boeing, and now L’Oréal. He shares what it takes to bring sustainable technologies to market, why economic viability is often the missing piece, and how large companies are rethinking their value chains from the inside out.
