Syensqo (pronounced “Science Co”) is a Belgian multinational chemicals and advanced materials company, headquartered in Brussels, Belgium. It was established in December 2023, through the spin-off from Solvay.[2][3][4] The current CEO is Mike Radossich, who succeeded Ilham Kadri in January 2026.[5][6]

Syensqo has been publicly listed since December 11, 2023 and joined the BEL20 soon after.[7] The company is present globally with 54 industrial sites and 12 major R&D centers, and it employs 13,000 people in 30 countries.[8]

History

In 2022, Solvay announced the intention to separate into two independent stock listed companies: Solvay and Syensqo.[9]

Solvay would retain its historic soda ash, Peroxides, Silica, and Coatis production, as well as the Specialty Chemicals division. The Materials, Composites, and Solutions divisions were split off into Syensqo.[10] The goal of separating the two companies was to give independence and flexibility in pursuing different strategies.[11]

The name Syensqo is explained as follows: SY represents the first and last letters in Solvay. EN is a nod to Solvay’s founder, Ernest Solvay. SYENS refers to Solvay’s scientific heritage, which goes back to 1911, when Ernest Solvay brought 24 scientists together for the first Solvay Conference. Q refers to quantum physics, which was discussed at the conference. QO is for company.[12]

On Friday, December 8, 2023,[13] shareholders approved the plan to split Solvay into two separate entities.[14][15] As a result, Ilham Kadri, former CEO of Solvay, became the CEO of Syensqo, whereas Philippe Kehren became the CEO of Solvay.[16]

The split became effective on December 11th, 2023, with shares listed on Euronext Brussels and Euronext Paris.[17][18][19] On September 16, 2024 Syensqo announced its intention to delist from Euronext Paris.[20][21]

Syensqo also recognizes scientific advancements and major discoveries through the Science for the Future Ernest Solvay Prize by Syensqo, previously known as the Solvay Prize. With the support of the Syensqo Fund, the prize is awarded to individuals who have made significant contributions in the field of chemistry. The recipient of the 2026 prize is Xiaowei Zhuang, Professor of Science at Harvard University and Investigator at the Howard Hughes Medical Institute, for her work in advanced molecular and cellular imaging.[77][78]
Previous prize laureates include scientists such as Peter G. Schultz (2013), Ben Feringa (2015), Susumu Kitagawa (2017), Carolyn Bertozzi (2020), Katalin Karikó (2022) and Omar Yaghi (2024)[79][80], some of whom have also received Nobel Prizes.[81][82][83][84][85]

Controversies

Syensqo produces a piece of the "Hermes 450" drone in its UK factory, for UAV Tactical Systems (a company co-owned by the Israeli Elbits Systems Ltd and the French Thales). The drone model was that used by Israel in the bombing of humanitarian workers from the NGO World Central Kitchen in Gaza, on April 1, 2024.[86]

In June 2025, activists blocked Syensqo headquarters in Brussels to demand the respect of the military embargo towards Israel (in place since 2009 in Belgium). “We make no secret of the fact that we are active in the defense industry value chain. But it's not weapons production, it's a mix of things”, Syensqo said.[87]
