PFAS project at Campus Vesta
Transformative soil cleanup results with advanced phytoremediation
Land: training site of Belgian fire brigade and police with historical PFAS pollution from firefighting foam.
Project approach: PFAS extraction from soil and groundwater with hemp, willows and natural soil additives.
- Initial Contamination: 0.5–30 µg/kgDM in the topsoil layer
- Treatment Levels in 1 plant cycle of 4 months: reduced to 0.5–12 µg/kgDM
- Project results in year 1: 67% overall PFAS reduction
- Project duration: ongoing, 3 years
Our innovative phytoremediation technique delivers outstanding results, significantly reducing soil contamination. Why our method works faster:
- Enhanced plant development: special additives boost plant growth while increasing PFAS mobility.
- Effective PFAS breakdown: These additives facilitate chain shortening and more pick up of PFAs by plants, making even stubborn PFAS accessible for absorption.
- Accelerated cleanup: speeds up the remediation process by up to 3x, delivering faster and more efficient results.
Collected biomass will go through the pollution destruction process and biochar production.
Experience the future of soil restoration - cleaner, greener, and quicker!

Hemp and willows clean PFAS from the ground in Ranst
At the provincial institute for safety training Campus Vesta in Ranst, experiments are being conducted to remove PFAS from the ground using willows and hemp. The trees and plants absorb polluted water so that the ground does not have to be dug up.

Hemp plants remove PFAS from the soil in Ranst
The area around the institute for safety training in Ranst is full of PFAS. This is due to the firefighting foam that was used there for a long time. A large project with hemp plants must now clean up the historically polluted site.
