Key Takeaways:

Frankfurt Airport (Fraport AG) is piloting a 200-meter stretch of airfield road made from innovative cashew-based asphalt, marking the first use of such biogenic material at an airport.
Developed by B2Square, this sustainable asphalt utilizes natural cashew shell extract, significantly reducing its carbon footprint, enhancing durability, incorporating atmospheric CO2, and minimizing energy consumption during application.
The initiative aims to reduce the airport's environmental impact, with potential for broader adoption across the apron area if the ongoing two-year performance monitoring proves successful.

Fraport AG, the operator of Frankfurt Airport (EDDF) in Germany, is kick-starting a new approach to sustainable construction by testing a 200-meter stretch of road on the airfield made from cashew-based asphalt. This material, developed by startup B2Square, is the first of its kind to be used at an airport.

Traditional asphalt is produced from petroleum by-products. In contrast, B2Square’s biogenic asphalt utilizes a natural hydrocarbon resin combined with an organic extract from cashew shells.
