Steve Smith, of Renew Energy Systems of Osage, made a proposal to the St. Ansgar School Board this week. He said his company's biomass boiler could save the school district up to 45 percent in heating costs over several years by burning things such as oat hulls and corn stover.
Smith said if the proposal is approved, the district could become to the first in the state to use biomass for all of its heating needs.
School board member Ed Kleinwort said officials are considering the proposal.
"It's a long way from being a done deal, but it is indeed something we want to look at," he said.
Smith said more meetings with city officials will take place in the coming weeks.
