An invasive beetle that attacks and kills ash trees are threatening a large portion of eastern Iowa.
There are about 25 counties and an estimated 60-million ash trees across eastern Iowa threatened by the Emerald Ash Borer.
However, researchers in the Iowa City area may have found a way to reuse ash tree wood.
They say the wood from threatened ash trees, mixed coal produces steam providing electricity as an energy source.
Ferman Milster, principle engineer for University of Iowa Office of Sustainability says they could use the renewable fuel to help power the campus.
