PFAS—a challenge and a responsibility
PFAS (per- and polyfluoroalkyl substances) are persistent industrial chemicals with particular functional properties. At the same time, PFAS are the subject of public attention because of their persistence and the fact that they can accumulate in the environment and potentially harm human health. Evonik takes a responsible approach to handling PFAS and is working actively to evaluate the risks and develop sustainable alternatives. We aim to minimize potential environmental impacts, respond to regulatory developments at an early stage, and promote the use of sustainable alternatives wherever this is technically and economically feasible.
Evonik markets small amounts of polymers classified as a subgroup of PFAS for the manufacture of medical products. In addition, the company uses small quantities of PFAS compounds, for instance, in the production of pharmaceutical active ingredients. We also produce small amounts of polyfluoroalkyl substances, which we mainly use in coatings to protect surfaces—for instance, from graffiti. To this end, Evonik is working hard to develop fluorine-free alternatives.
The EU’s proposed restriction of PFAS affects around 10,000 substances in almost all usage forms. Evonik sees the risk that implementing this proposal could have a massive impact—for example, by disrupting value chains—and prevent important applications in batteries, semiconductors, and renewable energy generation. In particular, the use of PFAS-coated pipes, valves, and seals in plant engineering could be banned in the medium term, which would affect entire industrial plants, including those operated by Evonik. This is why we are advocating balanced regulatory action in respect of PFAS.
