Summary

Researchers in South Korea have developed a new technique that transforms wet coffee grounds into a coal-like biochar fuel in just 90 seconds. The method uses a two-step process involving hydrothermal carbonization and microwave pyrolysis, turning the moisture content of coffee waste from an obstacle into an advantage. This approach offers a cleaner way to recycle the over 10 million tons of coffee waste generated globally each year, producing a carbon-neutral fuel that could help reduce reliance on fossil fuels.

Coffee is one of the world's favorite drinks, but it leaves behind mountains of soggy waste.

For years, one problem kept that waste from becoming useful fuel: it was simply too wet.

Now, researchers in South Korea have found a way to turn that moisture from an obstacle into an advantage, transforming discarded coffee grounds into a coal-like fuel in less than two minutes.
