ArcelorMittal USA on Tuesday was named a Energy Star Partner of the Year for sustained excellence by the U.S. Environmental Protection Agency and the U.S. Department of Energy.
ArcelorMittal, which operates steel mills in East Chicago and Burns Harbor, provides steel for the automobile, construction, household appliance and energy markets.
ArcelorMittal is one of 70 sustained excellence winners nationwide.
The company was recognized for its, "commitment to identifying and implementing innovative solutions to increase the sustainability of its operations, reduce greenhouse gas emissions, protect the environment and natural resources while saving energy and costs," according to a joint statement by the U.S. EPA and U.S. DOE.
Accomplishments by ArcelorMittal in 2012 noted in the award announcement include coordinating with other manufacturers, utilities and the EPA to host a meeting in Northwest Indiana to introduce manufacturers to EPA's Energy Star industrial energy management resources.
ArcelorMittal used variable frequency drives to trap steam and manage leaks, thereby improving motors. One plant saved $200,000 in electricity and another $200,000 in maintenance costs as a result of the work.
A boiler project transferring blast furnace gas to a new boiler generating steam and electricity is expected to save $20 million annually.
The company also reduced energy intensity by 3.6 percent, the equivalent of powering 224,470 homes for one year.
Award winners were chosen from nearly 20,000 Energy Star partners, including manufacturers, retailers, public schools, hospitals, real estate companies and home builders.
ArcelorMittal also operates a global research and development facility in East Chicago, a hot strip mill in Riverdale, a plate mill in Gary and processing and finishing joint venture facilities in New Carlisle.
