Blast furnaces that use coking coal generate the largest share of emissions in the steelmaking process.

A cohort of 16 northwest Indiana residents hope to bring cleaner steel to the Region. This comes as U.S. Steel and Cleveland Cliffs plan to extend the life of their coal-based blast furnaces.

International Recycling Group Erie’s recycling facility in Pennsylvania would make plastic pellets to replace coke in steel blast furnaces — which generate a lot of greenhouse gas emissions. But activists worry using the plastic would release hazardous chemicals into the air and storing it would be a fire hazard.

Climate advocates said the climate action plans for both companies look similar, and neither is particularly ambitious.

Gov. Eric Holcomb said the sale of U.S. Steel to a Japanese company reflects the need to remain competitive in a global marketplace.

A Northwestern steel plant announced plans to delay relining a blast furnace in Burns Harbor, Indiana. This comes after calls from advocates to abandon its plan to lock in “dirty” steel techniques.

Indiana is a powerhouse for steel manufacturing more than a quarter of all U.S. steel is made here. But the state could lose that title if it doesnt transition to a greener way of making steel. Thats according to a new report by the American Council for an Energy-Efficient Economy and the Citizens Action Coalition of Indiana.

A report by the Indiana Department of Environmental Management this week says U.S. Steel violated its permit when it released excess iron into a Lake Michigan waterway last month, causing it to turn a rusty color.

U.S. Steel Midwest idled the plant in Portage, about 30 miles east of Chicago, as a precaution after it said a wastewater treatment facility experienced “an upset condition” that sent the rusty colored plume containing elevated levels of lead into the Burns Waterway on Sunday.

State and federal environmental agencies are working with U.S. Steel to investigate the cause of the leak and find out if it's harmful.
