Biofuels

If Cleveland-Cliffs’ plans work out, the biofuel company it bought last week will soon help fuel taconite mines and power plants in Eveleth and Silver Bay, Minn. Once those plants are built, the Cleveland-based company will burn a mix of the cubes and coal to run its United Taconite Mine in Eveleth, its Northshore Mining power plant in Silver Bay and the Tilden Mine in Michigan, spokeswoman Maureen Talarico said. Dana Byrne, a Cleveland-Cliffs vice president, said Renewafuel’s technology “enables us to be proactive in addressing challenging environmental issues for us and the states in which we operate. The fuel cubes, which are about the size of a charcoal briquette, generate twice as much energy as other biofuels. The cubes were successfully tested at the University of Iowa’s power plant and in the Empire Iron Ore Mine in Michigan. Spokeswoman Talarico said Cleveland-Cliffs expects to produce 100,000 tons of the cubes per year in Battle Creek and 150,000 tons a year in Minnesota and at subsequent plants.
