Common Questions
Why is Solvay closing plants in Europe in 2026?
Solvay cited uncompetitive European energy costs compared to Asian and US producers. High TTF gas prices make energy-intensive processes like soda ash and peroxide production economically unviable.Source: Lowdown / JPMorgan
What is the difference between Solvay and Syensqo?
Solvay demerged in 2023-24 into Solvay (essential chemicals: soda ash, peroxides, silica) and Syensqo (advanced specialty materials for aerospace and electronics). Both are listed on Euronext Brussels.
Which European chemical companies are at risk from high energy prices in 2026?
JPMorgan identified Yara and BASF as facing EUR 2.5bn annual margin erosion at TTF above EUR 50. Ineos and Solvay have already confirmed plant closures in 2026.Source: JPMorgan / Lowdown

Background

Solvay is a Belgian specialty chemicals group founded in 1863, headquartered in Brussels, listed on Euronext Brussels (SOLB). In 2023-24 it split into two listed companies: Solvay (essential chemicals: soda ash, peroxides, silica) and Syensqo (specialty materials for aerospace and electronics). It operates energy-intensive production sites across Belgium, France, Germany, Italy, Spain, and Poland.

Solvay is closing European plants in 2026 due to uncompetitive energy costs. Cefic data showed European chemical capacity fell 37 million tonnes (9%) between 2022 and 2025, with Solvay and Ineos among plant-closers and approximately 20,000 jobs lost. European chemical exports fell from 23% to 14% of world trade 2018 to Q1 2026. Industry leaders frame the cost disadvantage as structural rather than cyclical; plants closed will not reopen unless European energy prices converge with Asian and US levels.

Why is Solvay closing European chemical plants in 2026?
Solvay is closing European plants because sustained high gas and electricity prices have made energy-intensive soda ash and peroxide production uncompetitive versus Asian and US producers. The cost disadvantage is now framed as structural rather than cyclical.Source: European Energy Markets, Update #2 and #11
What happened to Solvay in 2023 when it split into two companies?
In 2023-24 Solvay demerged into two separately listed companies: Solvay (essential chemicals including soda ash, peroxides, and silica) and Syensqo (advanced specialty materials for aerospace and electronics).Source: Solvay corporate announcement 2023
How much European chemical manufacturing capacity has been lost since 2022?
European chemical manufacturing capacity fell by approximately 37 million tonnes (9%) between 2022 and 2025, with around 20,000 direct jobs lost, according to Cefic data published April 2026.Source: European Energy Markets, Update #2
Is Solvay the same company as Syensqo?
No. In 2023-24 Solvay split into two separately listed entities: Solvay retains essential chemicals (soda ash, peroxides, silica) while Syensqo focuses on advanced specialty materials for aerospace and electronics.Source: Solvay demerger documentation
