Wet coffee waste becomes coal-grade fuel in under two minutes
BY THE OPTIMIST DAILY EDITORIAL TEAM Researchers at the Korea Institute of Geoscience and Mineral Resources developed a plasma-based process that converts wet coffee grounds into coal-grade biochar in under 90 seconds, with no pre-drying required. The system, described in Chemical Engineering Journal, uses high-temperature plasma flames to process moisture-rich biomass directly, with the water content working as part of the conversion rather than against it. Why wet biomass has been a persistent
