It turns out that coffee grounds are a valuable organic resource.

Researchers from the Melbourne University of Technology carried out a fascinating study.
They dried the coffee grounds and subjected them to pyrolysis at 350 degrees.
When the resulting biochar was incorporated into concrete, its strength improved by nearly 30%.
This approach has the potential to decrease sand extraction and help cafes eliminate excess waste.
