Australia: Boral Australia has launched Innovo, an asphalt system product that uses steel slag as a raw material amongst other recyclables. Recycled materials that can be used in the mix include steel slag, recycled plastics, tyres, recycled crushed glass, recycled asphalt pavement and printer toner. The product has been used in various projects in Queensland, New South Wales, Victoria, South Australia and Western Australia.

Japan: Taiheiyo Cement, JFE Steel and the Global Institute for Environmental Technology are working together to develop a carbon capture and storage system. The system will use wet alkaline earth metals extracted from steel slag to produce carbonates from exhaust gases at cement and steel plants. The partners are investigating the possibility of using these carbonates, specifically calcium carbonate and magnesium carbonate, as additives in cement production at Taiheiyo Cement’s plants. Taiheiyo Cement president Masafumi Shigehara said, “With the effects of climate change becoming apparent both in Japan and overseas, the importance of global warming counter-measures is increasing.”

World: Data from the World Steel Association shows that global crude steel production fell by 1.4% year-on-year to 443Mt in the first three months of 2020. Asia produced 316Mt of crude steel in the first quarter of 2020, a year-on-year decrease of 0.3%. The European Union (EU) produced 38.3Mt of crude steel in the first quarter of 2020, down by 10%. North America’s crude steel production fell by 4% to 29.5Mt.

US: The Slag Cement Association (SCA) data shows that slag cement shipments rose by 10.8% year-on-year to 3.8Mt in 2019 from 3.5Mt in 2018. This is the fourth consecutive year that slag cement shipments have increased at a rate of 10% or greater. The SCA collects shipment data from its members.

“We have seen a substantial increase in slag cement use as concrete professionals become more and more familiar with the product” said Ed Griffith, president of the SCA.
