INEOS is a privately held chemical company headquartered in Rolle, Switzerland. The company was formed in 1998 to acquire the assets of the BP site at Antwerp, Belgium from INSPEC. Since then, Ineos has been an aggressive acquirer of a variety of chemical manufacturing assets often those spun off from industry leaders including: Amoco, BASF, Bayer, Borealis, BP, Degussa, Dow, Enichem, Erdoichemie, Hoechst, ICI, Innovene, Lanxess, Monsanto, Norsk Hydro, and Solvay.
In 2014 Solvay and Ineos combined their chlor-alkali and vinyl business in a jv called Inovyn. The European Commission required the divestiture of certain plants. In 2015, the divested plants were sold to ICIG (International Chemical Investors Group). In 2014, Westlake Chemical increased its ownership of a PVC jv with Suzhou Huasu Plastics Co. in China by buying out the interest of INEOS, subject to government approval.
In 2015, Ineos announced plans to construct on 350K mt linear alpha olefins plant on the US Gulf Coast. Completion is expected in 2017.
