Sustainable management of PFAS contaminated materials (Less-PFAS)

Published: 16 October 2019

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.

P Fas LTU
Four ways to make free radicals that attack and break down PFAS molecules. The methods are tested separately and in combination.

They are so widespread through soil, groundwater and surface water, that nearly each of us already has PFAS in our blood. Since knowledge about the environmental and health effects of PFAS is still emerging, the problem has not been addressed sufficiently. Today's methods of dealing with PFAS-contaminated material - to dig up and transport them to landfills - are not sustainable. PFAS are very mobile and can still spread to water bodies through groundwater and landfill leachate. The need for development of cost efficient techniques that would enable the treatment of PFAS contaminated sites through destruction of these toxic and carcinogenic compounds is paramount.

The aim of this project is, in cooperation with partners from Sweden, Finland and Norway, and with the support of the industry, to optimize the existing and most promising PFAS destruction methods, and scale them up to practical solutions in field. The project will contribute to opportunities for enterprises with innovation activities in the region to grow and capitalize on environmental technologies that are developed within the project. The benefits in the long term will consist of reduced soil treatment costs and improved environmental quality through lower risks for pollution spreading as well as through the decreased amounts of toxic compounds in circulation.
