Next Step Biofuels' Russ Zeeck says these corn pellets could be a new form of renewable energy. They are made from the corn stalks, leafs and cobs left behind after harvest.
Plus, converting the corn plants into pellets makes them easier to ship.
Zeeck says coal-fired power plants can burn the corn pellets along with coal. Doing so might help reduce pollution, and the corn pellets would be considered a renewable source of energy.
