Buying the former biodiesel refinery at 5640 44th Ave South in Clinton, Iowa, presents a strategic opportunity for an investor to acquire a market-ready, operational asset in one of the nation’s top biofuel producing regions. The facility, situated in the Lincolnway Industrial Rail & Air Park, offers exceptional logistical advantages, including a direct connection to the Union Pacific main line and proximity to the Mississippi River, ensuring efficient distribution to major Midwest markets. The plant features established infrastructure, such as a 10-million-gallon annual capacity and an acid esterification pretreatment system that allows for diverse feedstocks. A new owner could leverage Iowa’s robust renewable fuel tax credits and infrastructure grants to either restart biodiesel production or repurpose the industrial space for other high-demand manufacturing or storage needs.  

Located in the Lincolnway Industrial Rail and Air Park, which is a heavy-industrial park strategically located in east central Iowa, on the Illinois border and within driving distance to the Chicago markets.  Iowa Site Certification was obtained in 2016.
