Article by Amanda Doyle Jim Stunkel, Research Technician at NREL, with the SAF A BIOREFINING process that converts wet waste – including food waste and wastewater sludge – into sustainable aviation fuel (SAF) has been developed by researchers in the US. The SAF could be used in commercial flights within a couple of years if approved. Wet waste includes food waste, animal manure, wastewater sludge, and waste fats, oils, and grease. Food waste sent to landfill produces methane and is responsible for around 6% of greenhouse gas emissions worldwide. Using it as a feedstock to produce fuel can...
Southwest Airlines Continues Dedication To Environment Through Sustainable Aviation Fuel Initiatives Carrier partners with National Renewable Energy Laboratory to advance alternative fuel exploration News provided by Share this article Southwest ® has undertaken multiple efforts over the years to minimize its carbon footprint and the Company continues to seek opportunities to help mitigate emissions. NREL presents one of those opportunities, as Southwest intends to continue to support NREL's work to develop low-carbon, low-cost, high-performance aviation fuels created from wet waste. Southwe...
Courtesy of University of Dayton Large aviation companies like Southwest Airlines are taking notice of the group's work in the DOE’s wet waste flight demonstration project to find a biorefining process to produce sustainable aviation fuels compatible with existing jet engines and capable of supporting net-zero flight. Net-zero is the point where the reduction of carbon emissions balances what's emitted by jet engines Josh Heyne, a University of Dayton aerospace engineering researcher and national expert on sustainable aviation fuel testing, and engineering graduate student Zhibin Yang con...
Novel pathway for aviation fuel from food waste–derived volatile fatty acids (VFA) could lead to 70% blends, up to 165% reduction in GHG Researchers from the National Renewable Energy Laboratory (NREL), the University of Dayton, Yale University, and Oak Ridge National Laboratory have demonstrated the production of sustainable aviation fuels (SAF) from food waste–derived volatile fatty acids (VFA) by targeting normal paraffins for a near-term path to market and branched isoparaffins to increase the renewable content in the long term. In an open-access paper published in Proceedings of th...
