Mogelijkheden van fytoremediatie voor saneren van PFAS

The objectives of the PLANTS study are as follows:

1. Investigate PFAS uptake mechanisms by plants: Examine the physiological, morphological, and genetic factors that contribute to differences in PFAS uptake among plant species and cultivars.
2. Assess soil influence on PFAS: Analyse how soil characteristics (texture, organic matter content, ..) impact PFAS sorption and bioavailability.
3. Map PFAS distribution in plants: Identify the locations and quantities of PFAS compounds within various plant tissues to develop a comprehensive mass balance. Evaluate also potential evapotranspiration/volatilisation
4. Assess the influence of soil life (rich vs poor, microorganisms, earthworms) on (partial) transformation of PFAS
5. Evaluate phytoremediation potential at field scale: Develop and optimise phytoremediation technologies at field scale (agricultural area, Blokkersdijk and private gardens). Operational conditions, for which PFAS compounds and soil conditions is phytoremediation a solution.
6. Social acceptance, context mapping: stakeholder consultation, development of a roadmap and assessment framework for the future implementation of phytoremediation, co-creation solutions
7. Investigate downstream processing of plant waste fractions: determine at which level of contamination plant biomass is no longer usable for composting, sorting plant waste fractions, timing of harvest, treatment methods of plant waste fractions (incineration, hydrothermal treatment,..)
8. Evaluation of the feasibility/implementation of phytoremediation at larger scale: economic feasibility, scalability, multi-criteria decision analyses
