In an ambitious move towards sustainable aviation, UK startup Firefly, in collaboration with Wizz Air, is pioneering the conversion of human waste into aircraft fuel. Based in Bristol, Firefly has developed a groundbreaking process to transform treated sewage into sustainable aviation fuel (SAF). Wizz Air, a low-cost airline, has shown its commitment by placing a significant order for Fireflys waste-based fuel, potentially amounting to hundreds of millions of pounds over the next 15 years.Commercial refinery to utilize biosolidsFireflys plan includes building a commercial refinery in Essex, with a pilot refinery already in the works in Harwich. This facility will utilize biosolids sourced from Anglian Water, converting them into usable aircraft fuel. What is the significance of this projectWhile traditional methods of producing SAF are costly and rely on limited waste feedstocks, Fireflys approach aims to provide a cheaper and more abundant solution. Paul Hilditch, Fireflys chief operations officer, describes the processed sewage as having the consistency of compost, with immense quantities readily available and currently of low value.🇬🇧 HUMAN WASTE MAY POWER YOUR NEXT FLIGHTBritish biofuel company Firefly has reached an agreement with the low-cost airline Wizz Air to build a commercial refinery that will help convert sewage into aviation fuel.Londons airports may be fueled by biofuel starting in 2028,… pic.twitter.com/3YxJTBr6Sq— Mario Nawfal (@MarioNawfal) April 13, 2024Although the SAF produced by Firefly is chemically identical to conventional jet fuel, regulatory testing is ongoing, and full-scale production hinges on securing necessary investments. However, Fireflys CEO, James Hygate, remains optimistic about delivering commercial supplies by 2028-29.Reducing carbon emissionsWizz Air sees SAF as crucial in reducing carbon emissions and aims to incorporate 10% SAF across its operations by 2030. The UK government also supports the shift towards sustainable aviation, expecting five commercial SAF plants to be under construction by 2025.Despite these advancements, some concerns linger regarding the sustainability of using human waste for aviation fuel. Critics argue that alternatives such as biomethane production may compete for the same resources. Additionally, questions arise regarding the carbon footprint of SAF production and its impact on soil enhancement compared to traditional agricultural use of biosolids.Nevertheless, proponents highlight the multifaceted benefits of converting sewage into jet fuel, including efficient waste disposal and potential global applications. As Fireflys Hilditch aptly puts it, Anywhere in the world where there are people, theres poo.
