Mitsubishi Chemical Group may close its methyl methacrylate (MMA) plant in Billingham, England. The facility, where methacrylates have been made since 1930, has been idle since January, initially because of a planned overhaul. However, it stayed closed because of a downturn in the European economy and rising natural gas costs due to the war in Ukraine. Mitsubishi plans to make a final decision next month. The plant has a capacity of 200,000 metric tons per year. In October, Mitsubishi delayed a final investment decision for a new MMA plant in Louisiana, citing market volatility.
