NSR AB is part of the project Reviving Baltic Resilience, which is an EU-funded project within the program Interreg South Baltic, where the University of Gdansk is the Lead Partner.

The project aims to prevent the discharge of dangerous and unwanted particles into the Baltic Sea, through technical solutions and cross-border cooperation within the South Baltic region.




PFAS (perfluorinated and polyfluorinated substances) is a group for about 3000 industrially produced chemicals. Since the 1950s, many products have been used in fire foam, impregnating agents and electronics, among other things. In general, the substances are water-soluble and are found in leachate from landfills and in stormwater from surfaces where materials with PFAS are handled. PFOS (perfluorooctane sulfonate) and PFOA (perfluorooctanoic acid) are the most noticed substances in the PFAS group. Because the environmental quality standard for, for example, PFOS in surface water is so low, there is a risk that many waste facilities will have problems diverting a leachate that has been treated in the traditional way because this type of treatment does not remove PFAS effectively. PFOS and PFOA have been identified as dangerous to both health and the environment.


NSR AB is carrying out a sub-project, where we are investigating three different facilities for purifying leachate from PFAS. We are testing a high-tech, a low-tech and a conventional facility. The facilities will be evaluated on the basis of the environment and economy.

Pilot plant for treatment of pfas NSR waste facility Helsingborg.

The purpose of the project at NSR is to compare two newer technologies for the purification of PFAS with the most proven technology on the market, carbon filters.

One of the innovation techniques is a high-tech filter method and the other is to be described as low-tech, a filter-based peat and ash from a previous incineration plant. During the experiments, the methods must be elucidated both from an economic perspective and with regard to performance.

Results and effects are implemented by analyzing the various parts of the process. The facilities will be evaluated on the basis of the environment and economy.
