Every year the world produces 10 billion kilograms of coffee waste globally.
Most of the coffee waste ends up in landfills and contributes to climate change.
Organic products like coffee grounds can't be added directly to concrete because they leak chemicals that weaken the building material's strength.
Using low energy levels the team heated coffee waste to over 350 C ( around 660 F ) while depriving it of oxygen.
