While the roster of feedstocks utilized for sustainable aviation fuel (SAF) continues to grow, one of the most ubiquitous and intriguing being explored by a UK company is sewage. Firefly Green Fuels has developed a process to turn human waste into SAF.A biofuels industry veteran, CEO James Hygate set out to find a low-value, abundant feedstock. “Globally, sewage is a material in constant production, it's an unavoidable byproduct of human existence,” he told AIN. “We know that in many places this sewage is already processed, leaving a tricky-to-dispose final product known as sewage sludge or biosolids. We are engaged in very productive talks with utility companies who are excited about the potential of our technology to take this problematic waste product off their hands.”  Using the proven ______ process, Firefly Green Fuels has successfully produced samples of SAF from sewage sludge and expects to submit its pathway to ATSM, the governing body for fuel standards, by the end of the year.The company has calculated that each person produces enough raw waste to make slightly more than one gallon of SAF a year. “Whilst there isn't nearly enough waste for this solution to power every flight in the world, we can make a significant impact towards reducing the aviation industry's fossil fuel dependency,” Hygate noted.Firefly expects its first commercial plant will come online before the end of the decade., plain_text
