And because steel is so capital-intensive, industry leaders will have to be convinced of the economic benefits of investing millions, if not billions, of dollars in new, sustainable technologies.
"Nobody is green for the sake of being green," said Richard J. Fruehan, co-director of Carnegie-Mellon Universitys Center for Iron and Steel Research in Pittsburgh. "There has got to be an economic incentive."
For many steelmakers, the economic incentive to do things differently came with an unprecedented increase in ferrous scrap prices.
