Why Firefly Green Fuels believes waste could decarbonise aviation

In this episode, Dirk Singer speaks with James Hygate, Founder and CEO of Firefly Green Fuels, about one of the more unconventional and potentially scalable sustainable aviation fuel pathways: converting sewage biosolids into jet fuel.Hygate discusses: Why Firefly is “feedstock-led”, and why that matters more than the technologyHow sewage biosolids emerged as the preferred feedstock for Firefly due to their abundance, consistency, and increasing difficulty of disposal.How hydrothermal liquefaction (HTL) works like “a pressure cooker” to turn sewage into biocrude and biochar Why Firefly believes its fuel could achieve over 90% lifecycle CO2 savings, potentially even becoming carbon-negativeHow sewage-to-SAF could scale in the UK  and why it could “come from left field” in mandate mathsWhat is required for SAF projects to be bankable including long-term feedstock supply and offtake agreementsHow sewage-based SAF can reach cost parity with Jet AIf you LOVED this episode, you’ll also love the conversation we had with Dr Mar Fernández-Méndez, Co-founder of MacroCarbon, who shares how the startup plans to turn seaweed into SAF.
