Southwest Airlines is partnering with SAFFiRE Renewables to build a pilot plant in Kansas that will convert corn waste into sustainable aviation fuel (SAF). The plant is expected to be operational by Q4 2025 and will produce cellulosic ethanol, which can be converted into SAF with a significantly lower carbon footprint than traditional jet fuel. This project is a major step towards making aviation more sustainable and highlights the potential of public-private partnerships in advancing biofuel technologies.
