Flint Hills Resources, an independent subsidiary of Koch Industries, has won an auction to purchase two ethanol plants owned by Hawkeye Growth. Both plants share the highly successful Fagen 110 million gallon design. The plants are in Menlo and Shell Rock. The auction was instituted by the primary lender, The Royal bank of Scotland plc even though Hawkeye Growth claimed that it was not in default. The owners of Hawkeye Growth were reportedly outbid.
