Per- and polyfluoroalkyl substances, or PFAS, are a frequently discussed topic in health and environmental protection. Once released, they remain in the environment for a long time, accumulate in the food chain, and can harm both humans and the environment. These substances, known as “forever chemicals,” are detectable worldwide in water, soil, plants, animals, and humans.

PFAS are used due to their thermal and chemical stability, as well as their water- and grease-repellent properties. They are found in items such as mobile phones, wind turbines, cosmetics, solar panels, medical devices, and rain jackets, and are difficult to replace in many of these products. Despite their widespread use, the European Chemicals Agency (ECHA) has proposed a ban on the production, use, and marketing of PFAS. Companies must now review their supply chains and find alternatives.
