Why Alto Ingredients Is Expanding Pekin Production Capacity
Read MoreHide Full Article
Key Takeaways
Alto Ingredients is expanding Pekin dry mill capacity by about 8%, adding roughly 5 million gallons annually.
ALTO expects higher production from Q4 2026, increasing gallons eligible for Section 45Z tax credits.
Alto Ingredients is adding logistics infrastructure to improve shipment flexibility and plant efficiency.
Alto Ingredients, Inc. (ALTO - Free Report) is investing in additional production capacity at the Pekin dry mill as it looks to improve operational efficiency while capturing greater value from favorable industry incentives. Rather than building new facilities, the company is focusing on debottlenecking its most efficient plant, a move designed to increase output with relatively modest capital investment while strengthening profitability.
The project will be completed during a planned outage in June and is expected to increase the Pekin dry mill's annual production capacity by about 8%, or roughly 5 million gallons. Alto Ingredients expects the higher production rates to begin contributing from the fourth quarter of 2026. The additional volumes are expected to do more than boost production. These are expected to help improve plant utilization and create additional margin opportunities by increasing the number of gallons eligible for Section 45Z clean fuel production tax credits.
The company is also investing in supporting infrastructure at Pekin. In the first quarter, Alto Ingredients started repairs on its original dock and began construction of a second alcohol loadout facility, which is expected to improve logistics and provide added flexibility for shipments.
The expansion highlights Alto Ingredients’ strategy of generating more value from existing assets rather than pursuing large-scale expansion projects. With higher output, better logistics and greater access to clean fuel incentives, Pekin is becoming a central part of the company's operational improvement efforts in 2026.
