Chevron to resume operations at Ralston, Iowa biodiesel plant

November 12, 2026 |

In Iowa, Chevron will resume operation at its biodiesel production facility in Ralston, Iowa. The restart is supported by a commercial and operational agreement between Chevron and farmer-owned Landus Cooperative, an Iowa-based agriculture services cooperative.

The decision follows improved biodiesel market conditions, and the neighboring Landus processing facility gives the plant an efficient feedstock supply chain. Landus has recently made updates to its Ralston processing facility. Ralston is well-positioned in the country’s second largest state for soybean farming, and the Landus facility processes more than 28 million bushels of soybeans a year, making it the largest mechanical crush facility in the U.S. 

Once fully operational, the Ralston facility will help increase the supply of biodiesel available to regional customers, support the broader diesel market and provide increased opportunities for soybeans raised by Iowa farmers. The restart is expected to create employment and contracting opportunities in the region, but timing and scope of workforce additions are still being assessed. 

At full production, Ralston has a biodiesel production capacity of nearly 42 million gallons per year, enough to fuel more than 275,000 typical 18-wheelers. Chevron idled the facility in 2024 after a market downturn.
