Solution for removing PFAS attracts funding

07/02/2025
Swiss start-up Oxyle has successfully closed a funding round that raised $16 million to scale its solution to remove PFAS from wastewater. This adds to a 2022 pre-seed round that brought in $3 million, and the total raised to $26 million including additional non-dilutive funding from grants and awards.

The start-up based in Zurich has developed a technology that doesn’t filter what are known as “forever chemicals”, but destroys the molecules, achieving over 99% elimination rates while consuming much less energy than alternative destruction methods, it said.

The company’s three-stage process combines foam fractionation, catalytic destruction, and machine-learning powered monitoring, in what is described as a modular system that eliminates the need for secondary waste disposal through incineration or landfilling.

The company was co-founded by Fajer Mushtaq and Silvan Staufert at ETH Zurich, where Ms Mushtaq earned her PhD in Micro- and Nanosystems focused on water remediation and Mr Staufert completed his PhD in Mechanical and Process Engineering.

The young team said it had already secured revenue-generating customer pilots for its first commercial operational installation. Last November, it deployed the full-scale system in Switzerland, treating 10 cubic meters of contaminated groundwater per hour at less than 1 kWh/m³.
