Ineos Inovyn has signed an agreement to sell 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, defense, and construction.
The site at Rosignano is Italy’s largest domestic chlor-alkali plant, producing caustic soda and chlorine. Tavazzano produces sodium hypochlorite.
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.
Esseco Industrial is the industrial holding company of Esseco Group, an Italian industrial group now in its fourth generation with a history spanning over a century. Operating in 10 countries with 8 production sites, including its chlor-alkali facilities in Pieve Vergonte and Saline di Volterra. Esseco Industrial employs approximately 725 people and serves 2,500 customers, offering products and services for the organic and inorganic chemical industries, with a specialization in sulfur derivatives and chlor-alkali.
