Investing in the Port of Stockton, Building a natural American Soda Ash Terminal

Denmar U.S. is proposing to build and operate a new, state-of-the-art export facility for American natural soda ash at the Port of Stockton, California. This facility will represent a robust and lasting investment in Stockton and San Joaquin County, helping the Port grow the local economy while ensuring Denmar can help meet the global demand for a domestically-produced, naturally occurring product.

What is Soda Ash?

Soda ash is an essential raw material used most frequently in the manufacturing of glass, as well as detergents, electric car batteries, and other household products. Used in manufacturing for more than 5,000 years, Denmar’s American natural soda ash is derived from Green River, WY in the largest natural deposit of soda ash in the world.


About 50 million years ago, volcanic activity, decaying plant matter, and climate change caused the evaporation of a large lake, leaving behind the world’s largest trona deposit located in Green River, Wyoming.
Ancient Egyptians dug up dry lakebed deposits, using soda ash to make glass ornaments and vessels.
Romans used soda ash for baking bread, making glass, and medicinal purposes.
Soda ash has been used in manufacturing for over 5,000 years.
Up until the 19th century, soda ash was extracted from the ashes of plants that grew in sodium- rich soil. The method was so common, it is how the powder received the name ‘soda ash.’
Now mined from trona deposits, soda ash is one of the world’s most abundant natural resources.

Why Stockton and San Joaquin County?

Our goal is to build a modern, safe and reliable export facility to help meet the growing global demand for American natural soda ash. Ideally located to reach global markets, the Port of Stockton offers existing infrastructure that will allow us to operate a facility with enough capacity to meet the demand for this important domestic commodity.

To ensure the project moves forward supporting local jobs, Denmar U.S. entered into a Letter-Of-Intent with the San Joaquin Building Trades Council for construction and will hire locally from Stockton’s strong workforce.

Investing in Stockton and San Joaquin County

Partnering with the San Joaquin County Building & Construction Trades Council

To ensure the project moves forward supporting local jobs for construction, Denmar U.S. entered into a Letter-of-Intent with the San Joaquin Building Trades Council. SJBTC represents 21 different construction trade union affiliates and more than 10,000 men and women, who work in the construction trade industry and live in San Joaquin, Calaveras and Alpine Counties.

Investing in New Jobs and Generating Local Tax Revenue

The new terminal will create more than 439 jobs and $38.3 million in local labor income annually during the two-year construction phase at a company with a strong safety record. At full capacity, the operation of this new terminal is expected to create 189 jobs and $17.8 million labor income each year in 2023 and 2024. Beginning annually in 2025, operations will expand to create 323 jobs and $32.4 million in labor income ongoing. By 2025, annual state and local tax revenues will grow to approximately $5 million, including $2 million in direct taxes and an additional $3 million in state and local tax payments supported through upstream business-to-business transactions and household consumption.

Building Lasting Roots in Stockton, San Joaquin County and across California’s Central Valley

Denmar U.S. will initially export 4.8 million tons per annum of American natural soda ash through the Port of Stockton, with plans to increase volumes over time to 7 million tons per annum, making a commitment to the local community through a significant capital investment.

Environmental Impact

Natural vs. Synthetic

Soda ash is a critical component for making everything from laundry detergents and recyclable glass to lithium batteries used in electric cars. Natural soda ash has been in use for more than 5,000 years, and our facility in Green River, Wyoming helps offset the need for synthetic soda ash, which is energy-intensive to make and produces substantial toxic byproducts. Today, American natural soda ash exports are offsetting the use of synthetic soda ash. Synthetic soda ash is carbon-intensive to make, largely from coal power and produces substantial toxic byproducts.

Clean and Efficient

Our soda ash is mined with no additional chemicals added. The product is pure, safe, water-soluble, nonhazardous, and effectively used to make products that help create a cleaner, safer environment.


The current timeline aims to begin construction later this next year, with an estimated facility opening in Q4 2022.
