The Kiyanly Polymer Factory (), inaugurated October 17, 2018, features design capacity to produce 381 thousand tonnes of polyethylene and 81 thousand tonnes of polypropylene per year. Built at a cost of US$3.4 billion by LG International, Hyundai Engineering, Toyo Engineering, and Gap Inşaat, the plant cracks methane and ethane for production of polymers. In the first ten months of 2019, however, the factory produced only 67,900 tonnes of polyethylene and 12,700 tonnes of polypropylene. As of January 2023, the polymer plant had reportedly ceased operation.
