Solvay plans to increase its annual production capacity of natural soda ash at its Green River plant in Wyoming, US, by 150,000 metric tons.

The increase, which is scheduled to come into play early next year, is required to meet the growing demand of its U.S. export markets.

“This capacity expansion is an important step in Solvay’s three-year action plan to reinforce its global leadership in soda ash by addressing different regional market dynamics. In line with the plan, announced last June, the Group is gradually expanding its U.S. production capacity by about 12%,” said Christophe Clemente, President of Solvay’s Soda Ash & Derivatives global business unit.

Green River’s industrial mining assets produce natural soda, used in glass manufacturing, from the trona mineral. Construction works have already begun to expand production capacity at Solvay’s Green River trona mine from more than 2 million metric tons a year.

Green River is Solvay’s largest U.S. production site, with more than 400 employees.
