Frankfurt Airport Tests Eco-Friendly Asphalt Made from Cashew Shells

The trial aims to reduce carbon emissions by replacing petroleum-based bitumen with a biogenic alternative.

Fraport AG is experimenting with a new asphalt on a 200-meter stretch, using cashew nutshell oil as a binder instead of traditional petroleum-based bitumen.
The biobitumen, developed by B2Square, claims to improve durability and significantly enhance the climate footprint compared to conventional materials.
Initial tests are being conducted on a taxiway where one side uses standard asphalt and the other uses the innovative cashew-based version.
The project is part of Fraport's broader goal to achieve a CO2-free ground operation by 2045.
Cashew nutshell liquid, a byproduct from tropical regions, is used in creating the new asphalt, offering a sustainable alternative to reduce construction-related emissions.
