Cancer Chemical Leaks: Manufacturer Faces Prosecution
4 Aug
Summary
- Huntsman Polyurethanes faces potential prosecution over benzene emissions.
- Emissions of carcinogenic benzene rose significantly between 2022 and 2024.
- Modeling showed benzene levels exceeding air quality standards by 933%.
The Environment Agency (EA) is investigating Huntsman Polyurethanes in Teesside for potential prosecution over emissions of benzene, a known carcinogen.
Documents reveal that a new process implemented in 2023, which replaced a benzene emission reduction system, has periodically paused. This resulted in benzene being directly released into the air. EA records show emissions increased from 13 tonnes in 2022 to 17 tonnes in 2024.
Independent modeling commissioned in March 2026 indicated significant breaches of legally binding air quality standards, with benzene emissions predicted to exceed the 24-hour limit by 933% in one scenario. Despite these findings, the EA stated that predicted environmental concentrations remain below relevant standards, and local air quality experts do not believe there is a significant risk to nearby schools.
However, campaigners and scientists criticize the EA's response as slow and inadequate, emphasizing that there is no safe level of benzene exposure. Huntsman maintains its emissions are compliant with its permit conditions, though the company refused to share its personal monitoring data with the Guardian or the EA. The EA has informed the UK Health Security Agency and the Health and Safety Executive.
