Green Steel : A UNSW/OneSteel collaboration UNSW’s world-first
patented “green steel” making process, Polymer Injection
Technology (PIT), is optomising electric arc furnace steelmaking
in Australia and overseas with significant environmental
benefits and cost savings. A productive partnership with the
Australian steel manufacturer, OneSteel, enabled UNSW to take
PIT through pilot trials and industrial testing to
commericalisation and licensing, in Australia and overseas.
Green steel was named in the 2012 List of Innovations that Could
Change the Way we Manufacture by the Society for Manufacturing
Engineers. The process, invented by Professor Veena Sahajwalla,
emerged from the novel proposition that waste plastics, or
polymers, and used tyres -- significant global waste burdens --
could be absorbed in EAF steel making; an industry which has
remained largely unchanged for decades in its reliance on coke
and coal. She discovered that by introducing a granulated blend
of carbon-based waste into an EA furnace at v
