An airline has placed an order for sustainable aviation fuel that is made from human waste. EcoWatch, established in 2005 as a newspaper in Ohio focused on the environment, is now a digital platform that publishes high-quality, science-based content on environmental topics, including issues, reasons, and solutions.
Wizz Air, a low-cost airline from Hungary, has made a purchase of sustainable aviation fuel (SAF) produced from organic waste materials.
A startup company in Bristol, UK called Firefly has created a sustainable aviation fuel (SAF) by converting treated sewage into fuel. Wizz Air has made a significant investment in this concept by ordering up to 525,000 metric tons of SAF from Firefly over the next 15 years, as reported by The Guardian.
Yvonne Moynihan, Wizz Air's corporate and ESG officer, expressed in a press release the importance of sustainable aviation fuel (SAF) in reducing carbon emissions in aviation. By investing in Firefly, Wizz Air aims to decrease their lifecycle emissions by 100,000 tonnes of CO2 equivalent annually, demonstrating their dedication to incorporating SAF into their operations by 2030.
The aviation industry contributes approximately 2% of worldwide carbon emissions, but innovations like Sustainable Aviation Fuel (SAF) can help lower the environmental impact of air travel. However, The Guardian noted that the development of SAF can be hindered by high costs and limited resources. SAFs can be pricier to produce compared to traditional aviation fuel, and many rely on materials like used cooking oil or food waste that may have limited availability.
Firefly observed that there is a significant amount of biosolids from treated sewage that is not very valuable and could be more cost-effective to convert into SAFs than other materials. It was also mentioned that sewage sludge can be mixed with up to 50% traditional fuel made from kerosene without requiring any changes to aircraft engines, as reported by Yahoo! Finance.
Firefly is currently testing the fuel they plan to use, and they are considering building a factory in Harwich, Essex, England, as reported by Yahoo! Finance. Anglian Water has made an agreement to provide the necessary biosolids for the facility to produce SAF. Firefly anticipates that they will be able to supply SAF by either 2028 or 2029.
Aside from aiding the airline in achieving its target of using SAF to fuel 10% of its flights by 2030, the purchase of SAF from Firefly could also assist Wizz Air in complying with the EU's regulations. These regulations mandate that flights departing from the EU must use 20% SAF by 2030 and increase to 70% SAF by 2050.
"Moynihan emphasized that reaching our goal will require a substantial increase in SAF production and implementation. As a result, it is important for policymakers to remove obstacles hindering the widespread use of SAF by offering incentives for production, ensuring stable prices, and exploring more sustainable sources for biofuel production."
