Overview of PFASs in waste stream and treatment options

The first seminar of Zero PFAS seminar series was held on November 26th, 2020. The aim of this seminar was to give the audience a start line for their action to tackle the PFASs issues.

"The seminar is the first of our three seminar-series in project Zero PFAS, and this was a starting point. We had to make sure the audience has the minimum level of knowledge to move the discussion further in the next coming seminars. We also hope that we seeded a sense of urgency in the issue to involve the policy makers as well as consumer to become aware of this issue," says project leader Mayumi Narongin Fujikawa from IVL Swedish Environmental Research Institute.

Presentation of Zero PFAS project

The seminar started with presentation of Zero PFAS project by project leaders Jing-Jing Yang and Mayumi Narongin-Fujikawa from IVL. Then the project partners around the Baltic Sea briefly presented the research status in their countries.

First up was Professor Magdalena Gajewska from Gdansk University of Technology, then Dr. Janis Rubulis from Riga Technical University. Both Poland and Latvia lack nationwide coordination of PFAS research, and they presented what further research can be useful to establish the national status of PFAS emissions. Then Professor Kai Bester from Aarhus University in Denmark and Associate Professor Lutz Ahrens from SLU (Swedish University of Agricultural Sciences) presented the Nordic advancement on the PFAS research. These short round table sessions concluded by the project financier Swedish Institute (SI), Dr. Gabor Schneider has presented the Baltic Leadership Programme and invited people to apply for SI’s new seed funding around the Baltic regions.

Tackle the PFASs issues

The program then continued with speakers, who are experts from different areas on tackling PFASs issues, where to start looking for PFASs, what it is, why it is important that we know and remove from the natural system.

Jonas Bermin from WSP, another environmental consultant company, explained what PFASs are. After we find out what and the vast amount of different PFAS compounds, it is important which PFASs is most hazardous and prioritized. The question is, where do we start looking among over 4000 PFASs? Associate Professor Leo Yeong from Örebro University shared his knowledge on analytical methods, and what analysis are available.

Investigate the wider picture

Then the programme moved on to investigate the wider picture, highlighting the dangers of PFASs. Where do PFASs come from? And what harm do they bring about to the nature and human bodies? Melissa Goicoechea Feldtmann from IVL started with the sources of PFASs, an eye-opener session that PFASs exist everywhere in our current lifestyles. We then had the pleasure to have Assistant Professor Carla Ng from University of Pittsburgh across the Atlantic to explain what consequences PFASs pollution has brought upon.

After a short break, Associate Professor Lutz Ahrens went through established PFAS removal technologies from waste stream, followed by Dr. Andriy Malovanyy from IVL with a case study of his work on PFAS removal project at R&D facility IVL Hammarby Sjöstadsverk in Stockholm, Sweden.

Watch the webinar on demand

The webinar had participants of over 150 people, and with the possibilities of post registration to listen to the recordings, the viewings have reached 200 people around the Baltic Sea. The webinar materials are available on this website, under Events.
