Once in full production, the Röhm Bay City plant will produce 250,000 metric tons of MMA annually while delivering several very tangible benefits: the new technology is based on the raw materials ethylene, natural gas and methanol and enables higher product yield, lower energy consumption and reduced water and waste impact compared to traditional production routes.

“Our investment in Röhm reflects Advent’s pursuit of helping to develop and grow innovative, world-class businesses and solutions. The Bay City plant implementing the new Lima technology brings sustainable and high-quality product to the growing U.S. MMA market, which is currently in a supply deficit in the U.S.,” said Ron Ayles, Managing Partner of Advent International. “We have invested at the right time in the right place and are now the sole C2-based producer in the U.S.. We look forward to our continued partnership with Röhm to further grow Röhm as the inventor and technology leader in methacrylates globally.”

Röhm has already received strong interest from its customers for MMA produced via its proprietary C2 process. The Bay City plant is ideally situated to serve both U.S. and global markets. “Demand is surpassing our initial expectations. In the coming weeks, we will diligently ramp up production rates and we are already evaluating further growth opportunities for our business,” said Bohnen.
