US: The US Department of Energy has awarded a grant of US$1.5m to a combined industry and academic team led by Cornell University’s School of Civil and Environmental Engineering. The team will research uses of slag and other waste products from steel production. The study aims to investigate the overall material efficiency of steel production in order to reduce waste. It will explore several avenues, including the use of recovered silica for heavy metals capture at industrial plants and the synthesis of calcium carbonate from slag for use in steel production. Additionally, the team hopes to produce useable iron oxide from the by-products.

Assistant professor Greeshma Gadikota said, “This exciting project directly addresses our societal mission of meeting our resource needs in an environmentally sustainable manner. Iron and steel use is ubiquitous in our infrastructure.” She added that the study is “A unique opportunity to engage and train our students in developing innovative technologies that are central to our ability to live.” The study’s title is ‘Integrated reuse and co-utilisation of slag, sludge and dust with inherent heavy metal capture and nanoscale calcium carbonate production as an enhanced fluxing agent in steel plants.’
