New plasma process converts wet coffee grounds into fuel in 90 seconds

Scientists have demonstrated a new plasma-based process that converts wet coffee waste into high-performance biochar without any pre-drying treatment. The technology could address one of the biggest challenges in biomass recycling while creating a valuable source of renewable fuel.

Developed by researchers at the Korea Institute of Geoscience and Mineral Resources (KIGAM), the system converts moisture-rich coffee grounds into carbon-rich biochar in less than two minutes. The resulting material delivers an energy content comparable to anthracite coal, offering a potential pathway for turning difficult waste streams into useful resources. Researchers believe the technology could help reduce waste disposal costs while expanding opportunities for decentralized waste-to-energy systems.
