SIOUX FALLS, SD-Ethanol manufacturer POET has opened its 76,000-sf office expansion of its headquarters here. The building at 4615 North Lewis Ave. is now 114,000 sf, and has 200 employees at the site.

The 20-year-old company, formerly known as Broin, has 21 ethanol production facilities in six states, including Iowa, Minnesota, Missouri, Michigan, Indiana and South Dakota. The firm is also under construction with six more facilities in Ohio, Minnesota and Indiana, says a company spokesman. POET produces about 1.1 billion gallons of ethanol a year, he says, and employs more than 1,300 people across the Midwest.

The building started out at 19,000 sf as an expansion of the Broin family farm in 1983, the spokesman tells, and was expanded to 36,000 sf in 2003. The company doubled its staff to 200 with this new expansion, the spokesman says.
