Turning Waste into Fuel: The Promise of Spent Coffee Grounds in Aviation

Recent research highlights the potential of spent coffee grounds (SCG), a prevalent lignocellulosic biomass waste in Europe, for the production of sustainable aviation fuel (SAF). Comprising approximately 50% carbohydrates and 30% lignin, SCG can be effectively fractionated using methanol and alcohol-glycerol solvent mixtures, paving the way for innovative recycling processes that contribute to renewable energy solutions and reduce reliance on fossil fuels.
