Soda ash consumption tends to increase in proportion to population and gross domestic product growth rates.

The Green River Basin in Wyoming holds the largest and one of the highest purity known deposits of trona ore in the world. Based upon current production rates and proven and probable reserves reported by Ciner, the reserve life of Ciner Wyoming LLC assets is well in excess of 60 years.
