A Global Leader in Soda Ash Production

Founded in 2015, Ciner (pronounced ‘jin-ner’) Resources Corporation is one of the leading low cost suppliers of natural soda ash. Our facility in Green River, Wyoming has been producing high-quality, environmentally-friendly soda ash and distributing it around the world since 1962.

Our success as a company is a direct result of our people and the values on which our company has been built…Leadership, Integrity, Respect and Commitment. They are not just words to us, they define who we are as a company and how we operate every day. We are very proud of the fact that not only is our soda ash produced in a world-class facility that has the fewest emissions per ton, but our employees take a lot of pride in nurturing a culture where safety is a value, not just a priority. It’s how we do business; it’s who we are. At Ciner we truly believe the most important thing to come out of the mine are the miners.

Together with our colleagues in Turkey, we are the world’s largest producer of low cost natural soda ash.

Headquartered in Atlanta, Georgia, we are a subsidiary of Ciner Enterprises Inc., the North American subsidiary of Ciner Group in Istanbul, Turkey, and London, UK.

Our mission is to nurture a culture founded on safety, supported by integrity, leadership, commitment, and respect. Ciner is committed to behavior-based principle-driven safety, health processes, and programs, led by effective management systems and employee involvement.

Every Ciner employee, from the plant in Green River, to our corporate headquarters in Atlanta, is empowered to modify any operation that poses a potential threat to themselves, their fellow workers, the surrounding community, or the environment.


Our stellar safety performance continues to speak for itself. Ciner Wyoming’s Big Island Mine and Production Facility is a four-time winner of the U.S. Department of Labor Sentinels of Safety award for being the country’s safest underground mine. Our mine and surface rescue teams are consistently among the best in the country, with seven national mine rescue and three international surface rescue championships.

Committed to our Environment

Ciner understands how important the environment is to our industry. We take pride in the fact that all of our products are made from naturally occurring ingredients. Soda ash is a mineral mined from the ground and refined with no additional chemicals added to the product. Our product is pure and safe enough to be added to food products that are consumed every day. In addition, Ciner soda ash is more environmentally friendly than other products that could be used in its place. Ciner is committed to working towards producing innovative, reliable, and safe products for the environment and for the future.

Recycle | Refine | Reuse

The natural soda ash industry in the Green River Basin uses evaporative crystallizer technology. Similar to all evaporative systems, a concentrated aqueous solution is introduced to maintain the purity and quality of the refined soda ash product. The run-off of this stream (a mixture of soda ash and water) is contained in holding ponds throughout the facility. Ciner has developed a unique solution to reduce the capacity of these ponds and recover the useable soda ash, effectively recovering waste while improving efficiencies. The purified soda ash crystals, chemically sodium carbonate decahydrate, is harvested from the ponds seasonally and introduced as an additional feedstock to complement the mining of trona ore to produce soda ash at the facility.
