SOUTH BEND, Ind. (AP) — A once-idled ethanol plant in South Bend is producing and shipping the fuel again.

Noble Americas bought the plant two years ago after a previous owner went bankrupt and the plant had to close. On Wednesday, Noble announced that the plant had begun shipping fuel within the past couple of months after an extensive retrofitting process.

Some of the equipment in the 30-year-old plant had to be replaced. Noble Americas’ President Bill Cronin says the company likely spent around $100 million on new equipment.

In addition to ethanol, the plant also produces carbon dioxide and distillers dried grains used for animal feeds.

The plant has 70 full-time employees.
