US chemicals firm Dow said today it will permanently close its ethylene cracker in Bohlen, Germany, and chlor-alkali and vinyl assets in nearby Schkopau, in the fourth quarter of 2027.
It will close its siloxanes plant in Barry, UK, in mid-2026.
"The shutdown of upstream assets in Europe will right-size regional capacity, reduce merchant sale exposure, and remove higher-cost, energy-intensive portions of Dow's portfolio in the region," the company said.
The assets were included in Dow's strategic review in April. It said at the time the sites were being considered for idling or closure.
The Bohlen cracker has a nameplate capacity of 540,000 t/yr of ethylene and a propylene capacity of 285,000 t/yr. It also has a butadiene extraction unit with a nameplate capacity of 105,000 t/yr.
At Schkopau, Dow has a membrane cell chlor-alkali capacity of 250,000 t/yr and 740,000 t/yr of ethylene dichloride capacity. The site previously had around 330,000 t/yr of capacity for chloride monomer (VCM) production, with two lines operating at the site, but Dow closed the larger of the two lines to reduce capacity to roughly 110,000 t/yr earlier in 2024.
Dow's polyethylene assets in Schkopau — a 210,000 t/yr LLD-HDPE unit and 108,000 t/yr LDPE unit — were not part of the review and will continue to operate. Dow said closure of the upstream assets would "improve our ability to supply profitable derivative demand and optimise margins". The PE units can utilise an ethylene pipeline that runs between them and Dow's storage and import infrastructure in Stade, Germany.
The extended lead-time of the closures will allow Dow to wind down existing contracts and give customers time to attempt to source alternative material. Customers include the former Dow polypropylene plant at Schkopau, which it sold to Brazil-based petrochemical company Braskem in 2011 and that receives feedstock propylene from the Boehlen cracker.
