Deal to sell Heron Lake Bioenergy falls through

In Minnesota, the deal to sell Heron Lake Bioenergy to Guardian Energy Heron Lake LLC, has fallen through, forcing the company to go back to its current 1,100 investors—many of them local farmers—to bail out the company’s $37.5 million in debt. The company suffered an operating loss of $33 million last year. Guardian Energy was formed by four ethanol companies who previously acquired an ethanol plant in Janesville in 2009.
