Closure Announcement
Dow plans to close its 94,000 tonnes/year polyether polyols plant in Tertre, Belgium, by the end of Q1 2026. This decision is part of a strategy to rationalize its European asset footprint due to persistent structural challenges.
Reasons for Closure
The closure is driven by high operating costs, particularly energy expenses, and a burdensome regulatory environment in Europe. Additionally, the European polyether polyols market faces weak demand from key sectors like automotive, appliances, and construction, along with excess production capacity. Increased imports from Asia have also reduced competitiveness.
Impact on Workforce
The shutdown will affect 37 Dow roles and 8 contractor positions at the Tertre site. Dow is working with local stakeholders and trade unions to comply with relevant information and consultation processes.
Wider European Strategy
The Tertre plant closure is part of Dow's broader strategy to optimize its European operations. This includes shutting down an ethylene cracker in Böhlen, Germany, and chlor-alkali and vinyl assets in Schkopau, Germany, by Q4 2027, as well as a basics siloxanes plant in Barry, U.K., by mid-2026.
Financial Objectives
These actions are expected to result in an Operating EBITDA uplift of approximately $200 million globally, with benefits starting in 2026 and full delivery by 2029. The strategy aims to enhance profitability by exiting high-cost, energy-intensive assets and aligning production capacity with market demand.
