Türkiye: Oyak Cement will convert Mill 3 at its Darıca integrated cement plant to a slag grinding unit, according to local press reports.
The company has submitted the project to the government and the environmental impact assessment process has reportedly begun. The US$252,000 investment will add 14 jobs. The modified facility will grind 1200t/day (360,000t/yr) of slag, along with 18,000t of limestone in its other mills.
Germany: Research by the FEhS Building Materials Institute has concluded that steel slags are environmentally safe to use as aggregates, even when impurities exceed limit values. The research concluded that slag samples with ‘excessive’ heavy metals content nonetheless released no contaminants when contained in finished concrete.
The institute called for an amendment to MVV technical building specifications to reflect real substance release rather than the amounts of substances contained.

US: Eco Material Technologies has opened its 50,000t/yr Blissville rail terminal in New York City. The company says that the terminal will distribute supplementary cementitious materials (SCMs), including harvested fly ash, to the New York Metropolitan Area. Precision Terminal Logistics will operate the site, using rail connections including the New York and Atlantic Railway to despatch deliveries. Eco Materials expects the facility to quickly reach full capacity due to ‘strong’ regional demand.
CEO Grant Quasha said that the terminal will help the alternative cement segment to reduce its reliance on imported steel slag as a raw material.
South Korea: Steel company Posco Group has partnered with seven South Korean cement and ready-mix concrete producers and five construction firms, along with the Korea Concrete Institute and the Research Institute of Industrial Science & Technology, to develop novel concretes from slag. The Korea Herald newspaper has reported that Posco Group will supply its slag for the development process.
The project aligns with Posco Group’s ‘super-gap’ future market-orientated innovation strategy.
