Freya Burton (LanzaTech) - Scaling Carbon Recycling Technology from Startup to Maturity

Freya Burton, Chief Sustainability Officer and Head of Europe at LanzaTech, discusses carbon recycling, sustainable aviation fuel, and the 20-year journey from a four-person startup to a public company on Episode 27 of Scaling Green Tech, a podcast by Adopter.

Burton describes how LanzaTech captures waste carbon from industrial sites such as steel mills and uses microbes to ferment it into ethanol, a process she likens to brewing beer with carbon instead of sugar and bacteria instead of yeast. She traces the company from its 2005 founding in New Zealand by Dr Sean Simpson and Dr Richard Forster, through a 2008 pilot and a 2012 demonstration plant in China, to its first commercial plant in 2018 and six plants today. The conversation turns to why LanzaTech narrowed its focus to sustainable aviation fuel after listing on the Nasdaq, and how it reframes its work around energy security and economic value rather than emissions alone. Burton also explains why getting fuels policy right has taken more than a decade of work across the UK, EU and US.

This episode is relevant for founders scaling capital-intensive climate tech, carbon capture and utilisation investors, sustainable aviation fuel producers and buyers, and policymakers working on fuels regulation.
