This announcement follows Ineos Styrolution’s prior announcement on June 11, 2024, in which it shared its decision to permanently close the Sarnia site by June 2026 based on the economics of the facility within the wider industry context. The operations in Sarnia have been shut down since April 2024 due to orders from regulatory authorities that forced the site to declare force majeure.

“Since announcing the difficult decision to permanently close our Sarnia site, we have conducted an extensive assessment to determine the operational viability of restarting the site on a temporary basis. Ultimately, the conclusion of the assessment was that temporarily restarting the site is not operationally feasible or economically justifiable,” said Ineos Styrolution’s CEO, Steve Harrington. “We are now focused on conducting a safe, responsible, and compliant closure process and supporting our employees, contractors, customers, and partners, including offering transition support for impacted employees. I want to extend my deepest appreciation to our Sarnia team for their contributions to our business over the years.”

While the precise date of the site closure is yet to be determined, Ineos Styrolution is working closely with all necessary parties and expects to complete the decommissioning and orderly wind-down process by early Q4 2025.
