Solvay SA, Brussels, Belgium, an advanced materials and specialty chemicals company, has announced plans to increase its soda ash and sodium bicarbonate production capacity by 600 kilotons in the US and 200 kilotons in Bulgaria. The company will invest a combined $202 million over the next 3 years.

Solvay’s soda ash production at its trona-based Green River site in Wyoming will increase by 600 kilotons to meet long-term global demand for various purposes. The company will also expand its sodium bicarbonate capacity by 200 kilotons in its Devnya plant in Bulgaria, addressing worldwide demand growth for flue-gas treatments that improve air quality. The Bulgaria plant is part of an existing 75-25 joint operation with Sisecam, and the new production line there is expected to be operational by the end of 2020. The line will produce Solvair sorbents, which are sodium-based solutions that treat exhaust gases from factories, incineration plants, and ships as well as Bicar Z, a sodium bicarbonate buffer for animal nutrition.
