US: St Marys Cement won three national awards at the Slag Cement in Sustainable Concrete Awards 2023. The producer won the awards for supplying its slag cement for the construction of Wixom Assembly Park in Wixom, Michigan; of 333 North Water in Milwaukee, Wisconsin, and of Excellerate Manufacturing in Appleton, Wisconsin.
US: Eagle Materials and Heidelberg Materials North America, through their joint venture Texas Lehigh Cement Company, are currently building a new slag cement plant in Houston, Texas. When operational, the plant will have a production capacity of 500,000t/yr. Texas Lehigh Cement Company expects it to enter operation later in mid-2024. The plant's production will supplement that of the company's existing Buda cement plant in Texas.
Netherlands: Ireland-based Ecocem has agreed a deal with Overslagbedrijf Moerdijk (OBM) to expand production and storage capacity at the company’s Moerdijk slag cement grinding plant. The project is intended to allow the unit to both produce and store the company’s advanced cement technology (ACT) product. It will quadruple the storage capacity for key materials at the site up to 40,000t. Ecocem has signed a long-term agreement to lease the site from OBM, who will manage the handling and storing materials on Ecocem’s behalf.
This expansion of the Moerdijk plant is part of Ecocem’s plans to expand its manufacturing and storage capacity to support the commercialisation of ACT across all its plants. It follows the expansion of its Dunkirk plant in France, which was announced in June 2023. These expansion plans will be supported by licencing and partnership strategies to accelerate availability and adoption of scalable low clinker cement at speed.
Conor O’Riain, Managing Director (Europe), at Ecocem, said: “We are increasing our capacity at all of our locations and our deal with OBM is a hugely important aspect of our expansion strategy. It will accelerate our ability to manufacture ACT our low clinker cement technology and make it available commercially by 2026. At the same time, we are actively pursuing licensing and partnership agreements in the construction industry to ensure the benefits of this technology are shared widely and we accelerate progress to Net Zero.”
In February 2024 Ecocem said that its ACT technology received an ETA (European Technical Assessment), which provides the technology with a route to full commercialisation by 2026.
Boliden announces upcoming alternative cement plant
22 March 2024Finland: Boliden says it has a developed a 95% reduced-CO2 alternative cement production process based on the use of slag. Nordic Daily News has reported that the process has received verification from ‘established players in the cement industry.’ A preliminary study is underway, wherein Boliden will establish a 250,000t/yr production plant. Additionally, the process extracts usable metal from slag.
US: The Department of Transportation has announced a US$5m initiative to investigate the use of steel slag in cement and concrete. This will take the form of a collaboration between the Department of Transportation and a selected US-based steel producer and university partner. The initiative seeks to reduce CO2 emissions in the production of building materials. Prospective participants may view the grant opportunity here.
Transport secretary Pete Buttigieg said "We're proud to make this funding available to help develop the next generation of construction materials so that the future of our transport infrastructure is more resilient, more sustainable and made in America.”
Robert Hampshire, deputy assistant secretary for research and technology and chief science officer, said “This funding initiative will develop and advance innovative materials and technologies that support the nation’s goals to decarbonise the transportation sector by 2050, strengthen resilience of the nation’s transportation infrastructure, and address adverse environmental impacts created by the transportation system.”

11 January 2024India: JSW Cement has appointed Finland-based Coolbrook to install its RotoDynamic Heater electric kiln technology at the Vijayagar steel works and slag and cement grinding plant in Karnataka. The Press Trust of India has reported that the partners expect the technology to reduce the CO2 emissions of the plant’s slag cement.
Heidelberg Materials North America inaugurates expanded Port Canaveral slag cement plant and terminal
26 May 2023US: Heidelberg Materials North America has inaugurated the Port Canaveral slag cement plant and terminal in Florida, following an expansion. MENAFN News has reported that the producer invested US$24m in the installation of a new roller press at the facility.
Heidelberg Materials North America said "Heidelberg Materials' investment in the Port Canaveral slag cement facility is reflective of our commitment to supporting sustainable and resilient construction projects in the state of Florida and throughout the country. It is also aligned with our goal to significantly reduce our carbon footprint by 2030 and another milestone in our overall strategy to grow our portfolio of more sustainable products, technologies and customer-focused solutions on the path to Net Zero."
Construction underway on India’s first slag road
08 March 2023India: Construction is underway on a section of National Highway 66 in Maharashtra which is being built of concrete made from ground granulated blast furnace slag (GGBFS) and slag cement. India Today News has reported that the Central Road Research Institute developed the technology, in partnership with the National Institute for Transforming India Aayog and the Council of Scientific and Industrial Research.
Australia: Hallett Group plans to establish a slag cement grinding plant in Port Augusta, South Australia. Magnet News has reported the cost of the project as US$83.9m, towards which the producer has received US$13.4m in government funding. The plant will produce cement using South Australian ground granulated blast furnace slag (GGBFS) from Nyrstar’s Port Pirie and Liberty Primary Steel’s Whyalla steel refineries and fly ash from the site of the former Port Augusta power plant. Its operations will be 100% renewably powered. An accompanying new distribution facility at Port Adelaide will ship the cement to markets. The project will create 50 new jobs.
When the Port Augusta grinding plant becomes operational in 2023, its products will reduce regional CO2 emissions by 300,000t/yr, subsequently rising to 1Mt/yr, according to the company’s expansion plans.
Hallett Group chief executive officer Kane Salisbury said "We're talking about 1% of the entire country's 2030 [CO2 reduction] commitment, delivered through this project." Salisbury added "We're looking at turning South Australia into a global leader in manufacturing green cement."
Poland: The Building Research Institute has issued environmental product declarations (EPDs) for Cemex Poland’s CEM III slag cement and five other cements produced at its Chełm and Rudniki cement plants and Gdynia grinding plant. The company additionally obtained EPD certification for its Vertua Classic and Vertua Plus concrete products, which contain cement produced using supplementary cementitious materials (SCMs).
Materials director Michał Grys said “For us, product certification is another important step towards sustainable construction and a sustainable future. EPD declarations provide our clients with additional confirmation of the properties of products offered by Cemex Poland. They also improve their chances of obtaining LEED or BREEAM certificates for their investments.”
