Frankfurt Airport in Germany is trying a new type of road material. It comes from cashew shells.
This eco-friendly asphalt, called bio-bitumen, is better for the natural world. Regular asphalt comes from oil. The airport says that this new asphalt will help it lower its pollution. The airport wants to reach no emissions by 2045. Bio-bitumen is also stronger and lasts longer than regular asphalt.
To test it, the airport uses bio-bitumen on one side of the road and regular asphalt on the other. If it works well, they plan to use more bio-bitumen in the future.
Difficult words: asphalt (material for making roads), regular (usual), pollution (bad things in water or air).
