The team’s fuel from food waste resulted in a 165% drop in net carbon emissions compared to fossil jet fuel, not only because it’s cleaner, but also because the process removes millions of tons of food waste from landfills nationwide where it would produce methane, a greenhouse gas over 20 times more potent than carbon dioxide. NREL’s analysis team has shown U.S. wet waste, including food waste, has enough energy content to replace about 20% of U.S. jet fuel consumption. The group aspires to someday blend up to 70% of a version of its sustainable aviation fuel with conventional jet fuel.
