Employees raise concerns over corrosive residue from teflon plant in North Zealand, Denmark

For decades, a North Zealand teflon manufacturing facility has faced recurring issues with corrosive residue falling from its stack, according to numerous former employees who worked there between 2000 and 2023. Kenny Johannes Madsen, who was employed at the plant during the 2000s, stated, “It happened quite often and persisted throughout my time there. It was a well-known phenomenon.”

This residue has reportedly caused damage to employees’ vehicles. Brian Pedersen, who left the company in 2023, described the visible marks on his car, stating, “It was clear whenever I had been there. I knew it could not be washed off; it required polishing.”

The plant specializes in metal surface treatment and utilizes PFAS chemicals, commonly associated with Teflon. Professor Lisbeth E. Knudsen from the University of Copenhagen emphasized that the heating processes likely contribute to the corrosive fallout, commenting, “For decades, allowing these caustic substances to drip from the chimney is highly irresponsible.”

Interviews with ten past workers revealed a consistent pattern of similar issues. One anonymous employee from the 2010s noted, “Stains that were difficult to remove persisted throughout my employment, and the problem remained unresolved during my time.”

Accoat’s management claims the incidents are isolated and acknowledges past failures to resolve them quickly. They reported three such cases since 2020. However, local authorities have begun investigating PFAS contamination around the facility, located near residential areas and schools. Concerns are growing as questions arise about potential emissions from the plant.

Even with mitigation efforts in place, employees and experts express ongoing concern regarding the nature of the residue. Some believe that the associated risks and long-term ramifications remain inadequately addressed.
