April 21, 2026 [INEOS]- INEOS Inovyn has signed an agreement for the sale of its shares in INOVYN Produzione Italia SpA, which operates the Rosignano and Tavazzano sites in Italy, to Esseco Industrial.

The Rosignano and Tavazzano sites in Italy produce essential chemicals that underpin critical sectors, including pharmaceuticals, energy, water treatment, food, defence and construction.

The site at Rosignano is Italy’s largest domestic chlor-alkali plant, producing caustic soda and chlorine, which employs over 160 staff. Tavazzano produces sodium hypochlorite and employs 25 staff.

The transaction, which remains subject to the customary regulatory approvals, is expected to be completed during 2026. Until then INEOS Inovyn will continue to manage both sites, with no change to existing customer or supplier arrangements.

INEOS Inovyn’s R&D activity based in Rosignano will remain with INEOS Inovyn and will be carved out, subject to any consultation process required by applicable law.
