Amid rising global energy uncertainty triggered by ongoing geopolitical conflicts and fuel supply concerns, a Midwestern ethanol plant in the United States has expanded its production capacity from 40 million gallons per year (MMGY) to 105 MMGY using a new engineering optimisation program, Chemanalyst.News reported.
The expansion was carried out by RCM Technologies through its division RCM Thermal Kinetics under the NEXT (New Ethanol eXpansion Technology) program, launched in early 2025 to help ethanol producers increase output from existing facilities without major equipment replacement.
The project marks the first completed engineering installation under the NEXT program. Originally designed to produce 40 MMGY, the plant has now crossed the 100-million-gallon production level while continuing to operate with its original distillation columns and without installing parallel columns.
Before the latest upgrade, the facility had already expanded its output to 65 MMGY and later to 86 MMGY with support from Thermal Kinetics. For many years, that level was considered the practical production limit for more than 100 ethanol plants built under the same design model across North America.
According to Christopher J. Brown of RCM Technologies, the breakthrough was achieved through process optimisation techniques developed by senior engineer Roy Viteri. Instead of replacing major equipment, the team applied targeted engineering improvements that unlocked additional capacity within the plant’s existing infrastructure.
The expansion to 105 MMGY sets a new benchmark for ethanol plants designed under the traditional 40-MMGY model and demonstrates how modern engineering can significantly increase production while avoiding heavy capital investment.
Scott Yenzer, General Manager for Industrial Markets, said the project is the first completed installation under the NEXT program and highlights the growing interest from ethanol producers seeking to improve efficiency and reduce production costs as demand for alternative fuels rises worldwide.
