Sustainable management of PFAS-contaminated materials
Per- and polyfluoroalkyl substances (PFAS) are extremely stable chemical compounds, widely used in multiple applications and products worldwide. Due to their chemical stability, PFAS are extremely difficult to break down, which means that the substances spreads over large areas and accumulate in nature over time. The specific aims of the Less-PFAS project are to:
- To develop a sorbent that combined with the specific degradation technique could be applied to clean water and simultaneously destroy PFAS.
- To optimise existing PFAS degradation techniques and scale them up to practically applicable methods in field.
- To demonstrate/validate the techniques on a pilot scale.
- To provide companies with ready-to use techniques to clean PFAS contaminated soil and water.
- To spread the information about the chemical itself and about the possibilities to sustainably manage PFAS-contaminated materials.
Less-PFAS is financed by the EU program Interreg Nord. University of Oulu is also receiving co-financing from the Regional Council of Lapland.
