Wizz Air, a budget airline based in Hungary, is pioneering a revolutionary step in sustainable travel by embracing a new form of sustainable aviation fuel (SAF) derived from an unconventional source: human waste. This commitment involves a significant order from Bristol-based startup Firefly, which specializes in transforming treated sewage into viable fuel. Over the next 15 years, Wizz Air plans to integrate up to 525,000 metric tons of this eco-friendly fuel into its operations, a move poised to dramatically decrease the airline’s carbon emissions and set a new standard in the industry.

Firefly’s innovative technology not only recycles waste but also promises to reduce lifecycle emissions by 100,000 tonnes of CO2-equivalent per year for Wizz Air. This development is particularly timely, as the aviation industry, responsible for about 2% of global carbon emissions, faces growing pressure to reduce its environmental footprint.

The technical aspects of Firefly’s SAF are impressive; the fuel can be mixed in a 50:50 ratio with conventional kerosene without any modifications to aircraft engines. Plans for a production facility in Harwich, Essex, are underway, with operations expected to start between 2028 and 2029. This facility will mark a significant step forward in scaling up the production of SAFs to meet growing industry needs.

Yvonne Moynihan, Corporate and ESG Officer at Wizz Air, highlighted the strategic importance of this initiative. “Alongside fleet renewal and operational efficiency, sustainable aviation fuel plays a crucial role in reducing carbon emissions from aviation,” she stated. “Our investment in Firefly underscores our commitment to mainstream the use of SAF in our operations by 2030.”

The environmental benefits of using SAF derived from human waste are clear. This SAF is projected to deliver a 90% reduction in greenhouse gas emissions compared to traditional fossil jet fuel over its lifecycle. However, the path to integrating SAF into daily operations is fraught with challenges, including high development costs and the sheer scale of production needed to meet global aviation demands.

Despite these hurdles, the aviation industry has steadily increased its focus on sustainable fuel options to mitigate its impact on the environment. Wizz Air’s initiative is among the first to utilize human waste as a primary resource, potentially setting a transformative precedent for the sector.

The implications of this development extend beyond immediate environmental benefits. Success in this venture could catalyze a significant shift in how airlines across the globe approach carbon reduction. The looming regulatory mandates from the EU, which require significant increases in SAF usage by 2030 and 2050, underscore the urgency and importance of these innovations.

Moynihan remarked, “Achieving our aspiration requires a significant ramp-up of SAF production and deployment. Therefore, we call on policymakers to address barriers to SAF deployment at scale by incentivizing production, providing price support, and embracing additional sustainable feedstocks for biofuel production.”
