The Green River area in Sweetwater County is known as the "Trona Capital of the World." So, what is trona? It is a naturally-occurring mineral that is chemically known as sodium sesquicarbonate. Trona is the raw material which is refined into soda ash. Soda ash, in turn, is used to make glass, paper products, laundry detergents, and many other products. It also is used in the manufacturing of other chemicals, such as sodium bicarbonate (baking soda) and sodium phosphates (detergents). These major area employers, located west of Green River, include:
