Fraport AG, the operator of Frankfurt Airport, is kickstarting 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 the 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.
This process reduces the material’s carbon footprint and enhances its durability, the airport said in a news release. By incorporating carbon dioxide from the atmosphere into the asphalt, the material helps offset greenhouse gas emissions. Additionally, the low-temperature application method further minimizes energy consumption.
Fraport’s environmental management department views this sustainable asphalt as a significant step toward reducing the airport’s carbon footprint. If the test proves successful, the airport could expand the use of this material throughout the apron area.
According to the airport, the test stretch is being closely monitored by an independent laboratory to assess the asphalt’s long-term performance and durability over the next two years.
