The former Minnesota Energy plant in Buffalo Lake is seeing new life as trucks began carrying ethanol out of the gates on Tuesday. Steve Walker and Patrick Riggs started production in July after purchasing the plant and making about $2-million in upgrades to the facility. Now called Purified Renewable Energy LLC, the co-owners anticipate that ethanol will remain primarily corn-based for the immediate future, but also expect to use other feedstock and agriculture waste to produce the alternative fuel. They’ll be looking for ways to involve a variety of products in production as the ongoing drought continues to push the cost of corn upwards. The Buffalo Lake facility is licensed to produce upwards of 25-million gallons of ethanol per-year, and currently employs around 30 people.
