Europe’s Water Revolution Targets PFAS Destruction

Utilities adopt new tech to destroy PFAS as Europe enforces strict clean-water rules

17 Mar 2025

Europe’s water utilities are moving swiftly to confront a growing public health concern: the persistence of per- and polyfluoroalkyl substances, known as PFAS, in drinking water. Tougher national limits and mounting public scrutiny have prompted a shift away from simply filtering the chemicals toward technologies designed to break them down entirely.

PFAS, often called “forever chemicals” for their resistance to degradation, were widely used in products such as nonstick cookware and firefighting foams. In recent years, regulators have tightened standards as evidence of environmental and health risks has mounted. Sweden, for example, has set a limit of 4 nanograms per liter for certain PFAS compounds in drinking water, a threshold that strains many conventional treatment systems.

In response, companies are promoting methods that aim to destroy the compounds rather than capture and store them. The Swiss firm Oxyle has partnered with the Belgian water treatment company Waterleau to deploy a catalytic treatment system in Europe. After what the companies described as a successful rollout in Halle, Belgium, pilot projects are being prepared in France and Italy. According to company statements, the process reduces PFAS to near-zero levels without generating hazardous byproducts, offering an alternative to carbon filtration and high-temperature incineration.

Axine, working with Nijhuis Saur Industries, is targeting industrial sources of contamination. Its electraCLEAR process uses electricity to break down PFAS at the source, an approach aimed at sectors such as electronics and textiles, where contamination risks can be concentrated. The companies say the system includes installation and monitoring services intended to help facilities meet tightening regulatory requirements.

Procurement standards are beginning to reflect the shift. Tenders in Belgium, Italy and other countries increasingly call for proof of near-total PFAS elimination rather than partial reduction, according to industry officials.

Still, challenges remain, including energy demands and affordability for smaller utilities. With public awareness rising and European funding expanding, however, the emphasis on permanent destruction appears likely to shape water policy and investment decisions in the years ahead.
