Expansion planned at Green Bison Soy Processing

<![CDATA[

SPIRITWOOD, N.D. — Green Bison Soy Processing is among four soybean crush facilities where ADM plans to upgrade equipment to expand North American oilseed crush capacity and “strengthen the company’s ability to meet growing demand for renewable fuels and other vegetable oil markets.”

In a news release on July 30, 2026, ADM said investments at four of its soybean crush plants will “unlock approximately 700,000 metric tons of additional annual crush capacity across the four facilities, equating to more than 25 million bushels of new demand for American farmers.”

The other facilities in which ADM plans to invest are in Frankfort, Indiana; Deerfield, Missouri; and Lincoln, Nebraska.

Green Bison Soy Processing, in Spiritwood, east of Jamestown, North Dakota, began operations during 2023. The plant is a joint venture between ADM, which is the 75% owner, and Marathon Petroleum, which owns the other 25%. The plant was North Dakota’s first dedicated soybean crushing plant and refinery. The plant has a processing capacity of 150,000 bushels of soybeans per day.

Evan Montgomery, chairman of the North Dakota Soybean Council, said he was “as shocked as anybody” to hear ADM plans to expand capacity at Green Bison, given how new the facility is and how expensive building projects are right now.

“To see the level of support, either on the biofuel side or on the production side, that they’re able to expand, is great,” he said. “That’s a fantastic sign that tells me … we’ve got the soybean production here, and they must have the demand on the other side.”

Green Bison is one of two crush plants in North Dakota, with North Dakota Soybean Processors having opened its plant in Casselton in 2024.

“These investments reflect ADM’s continued focus on targeted growth opportunities in areas where long-term demand trends are creating new opportunities for farmers and customers,” said Gary McGuigan, president of ADM’s North America Ag Services and Oilseeds business, in a statement. “Strong demand — supported by biofuels policy in the U.S. — is driving opportunities for farmers and the broader American agricultural sector. By choosing to build on our existing footprint and adopting individualized enhancement plans for each facility, we’re ensuring that we are investing wisely and preserving flexibility while ultimately delivering a meaningful increase in capacity across our North American network.”

The statement from ADM said: “The Spiritwood, North Dakota, facility operated through the Green Bison joint venture with Marathon Petroleum Corporation will benefit from operational optimization and select equipment improvements. Work is expected to be completed in mid-2028.”

ADM says it is evaluating other North American crush locations for similar future investments. The company already is upgrading its Clinton, Iowa, corn facility and capacity expansions at its elevator in Optima, Oklahoma.

“These investments will help connect more American farmers to growing domestic and global markets while strengthening the infrastructure that supports U.S. agriculture,” McGuigan said. “We’re proud to continue investing alongside the farmers, communities and colleagues who make these operations successful.”
