PALISADES, NEW YORK — Peter Kelemen spends time in Oman looking for ways to pull carbon out of the air and put it back underground. His colleague, David Goldberg, looks at ways to store it far below the sea floor off the Oregon coast. Chemical engineer Alissa Park is working with steel mills in China to turn slag and waste carbon dioxide into reusable material.
The Columbia University-Baotou Steel EcoPartnership Launches Joint-Venture Pilot Project to Test and Commercialize Technology to Repurpose Iron and Steel Slags
On May 25, 2017, Columbia University and Baotou Steel launched the joint-venture pilot project at the Columbia Beijing Center. This event consisted of a panel discussion and press conference. Details of the groundbreaking new technology and the planning of the pilot in China’s Inner Mongolia Autonomous Region were discussed for the first time by Columbia engineering researchers, Alissa Park and Xiaozhou Zhou. The pilot project will start construction in Bao Steel plants in Inner Mongolia in the summer of 2017 and is expected to be finished in the summer of 2018.
China currently manufactures half of the world’s iron and steel through a process that leaves enormous amounts of waste, or slag, to accumulate in landfills or in stockpiles out in the open where its toxic elements may cause environmental and health problems. In partnership with a major iron and steel company in China, two Columbia engineering researchers hope to repurpose some of this slag for use in a range of industries, including paper, plastic, paint, cement, oil, and gas.
