Emergency crews are responding to a large fire at the Thommen AG recycling facility in Kaiseraugst, Aargau, which began at 10:10 p.m. on Tuesday. Dense black smoke is visible over the area, and a large contingent of firefighters is currently on-site. While initial reports suggest there are no injuries, there has been no official confirmation from authorities regarding the status of staff or the cause of the blaze.
Did You Know? The Thommen AG facility in Kaiseraugst experienced a significant fire as recently as January 2025, which authorities confirmed was sparked by a forklift and spread from a hall to an office building.
Operational risks in the recycling sector
The fire highlights the recurring safety challenges inherent in the recycling and waste management industry. According to a previous statement from a Thommen AG employee, the shredding of various materials frequently creates hazardous conditions. The employee noted that high-speed machinery can eject debris, which in turn generates sparks capable of igniting fires. The worker described the environment as a “risk job” where explosions and fire department interventions have occurred in the past.

What could happen next?
Given the scale of the current operation and the company’s history of incidents, the primary next step involves a formal investigation by the Aargau Cantonal Police to determine the ignition source. If the fire is linked to operational processes like the previous January incident, local authorities may conduct a review of safety protocols at the site. Future developments will likely depend on the containment of the fire and the subsequent assessment of structural damage to the facility’s processing halls and office buildings.
