Heidelberg Materials North America held an official opening ceremony this week for its upgraded slag cement plant and terminal at Cape Canaveral in Florida. The US$24m project added a new roller press to the unit to increase its production capacity. In a statement Chris Ward, the president and chief executive officer of the company, said that it had made the investment to meet sustainability and resilient construction goals. Industrial Accessories Company (IAC) said in mid-2021 that it had been named as the engineering, procurement, and construction (EPC) contractor for the project. It planned to install a hydraulic roller press supplied by FLSmidth. IAC also said it was providing instrumentation equipment, hoppers, bins, belt conveyors, bucket elevators and dust collectors amongst other kit and services.

Other recent US slag cement-related news stories have concerned terminals. In late August 2022 Royal White Cement said it had leased a site on the Houston Ship Channel in Houston, Texas to handle and store approximately 100,000t of multiple cementitous products such as slag, ordinary Portland cement and white Cement. In May 2022 Titan America announced plans to spend US$37m on an upgrade to its Norfolk terminal in Chesapeake, Virginia. The major improvement was to add a 70,000t storage dome, with enlarged truck and railway capacity, to allow the site to import and distribute raw materials such as fly ash, slag and aggregates. Completion on this one was scheduled for some point in 2023. Titan added that the project was similar to the addition of a 70,000t dome under construction at the time at Titan's import terminal in Tampa, Florida.

The United States Geological Survey (USGS) estimates that domestic sales of iron and steel (ferrous) slags in the US amounted to 15Mt in 2022. Sales were around 20Mt in the 2000s but this fell to current levels in the 2010s as blast furnaces closed. In 2022 the USGS noted that, “domestic ground granulated blast furnace slag (GGBFS) remained in limited supply because granulation cooling was known to be available at only two active US blast furnaces while, elsewhere, only one domestic plant produced pelletised slag in limited supply.” It added that the grinding of granulated blast furnace slag was only being carried out domestically by cement companies. Imports of slag were 2Mt in 2022. This is a decline from a peak of 2.6Mt in 2018 but higher than the period 2000 – 2015. The price of slag, meanwhile, hit a high of US$53/t in 2022. This is the highest price recorded by the USGS since at least 2000. It is double that of 2017.

Charles Zeynel of ZAG International noted in the June 2023 issue of Global Cement Magazine that cement producers in Florida, California, Texas, Georgia and the Carolinas are far from steel mills, so they import granulated blast furnace slag (GBFS) and other secondary cementitious materials (SCM). This certainly fits with Heidelberg Materials’ plan to upgrade its slag cement plant and terminal at Cape Canaveral. Also on the US market, Zeynel added that due to rising global demand for SCMs more of the available share of GBFS was being purchased by ‘richer’ markets such as Europe, North America and Australia. He continued that GBFS and GGBFS producers had also started increasing the price of their wares internationally. This too is apparent in the prices published by the USGS.

One final story with links to slag to note this week concerns the launch of the Alliance for Low-Carbon Cement & Concrete (ALCC) in Europe. The group brings together companies producing products or services intended to decarbonise the cement and concrete sectors. Two of the members – Ecocem and Hoffman Green Cement Technologies – are Europe-based slag cement producers. Two other members – Fortera and TerraCO₂ – are companies based in North America that are marketing and selling low-carbon SCMs.

Various start-up companies have been emerging on a regular basis in both North America and Europe with the aim of decarbonising cement and concrete in various different ways. The formation of the ALCC can be seen as part of this trend as the more successful non-traditional cement-concrete-aggregate companies establish themselves. One point that cement producers in North America are likely to be well aware of is that concrete is becoming less linked to clinker as the cost of carbon mounts and the clinker factor of cement lowers. Slag supplies may be finite but Heidelberg Materials North America’s latest investment in Florida is further acceptance that one doesn’t just need clinker to make concrete.

The 15th Global Slag Conference, Exhibition & Awards take place on 6 - 7 June 2023 in Düsseldorf, Germany

Finland: Finnsementti is carrying out upgrades to its two integrated cement plants as part of its sustainability targets to 2030. The subsidiary of Ireland-based CRH is installing new main burner equipment at its Lappeenranta plant with completion scheduled for mid-2023. The project is intended to allow the plant to increase its use of alternative fuels. The company’s Parainen plant is replacing its satellite coolers with a grate cooler with completion scheduled for the spring of 2024. This work is expected to decrease the plant’s emissions by 10%. Overall the group is preparing to decrease its CO₂ emissions by 30% by 2030 compared to 2021 levels.

Sweden: Heidelberg Materials Sweden has called for swifter action to be taken by the government on a planned upgrade to the mains electricity supply to the island of Gotland. The building materials company is planning to build a full-scale carbon capture and sequestration (CCS) unit at its integrated Slite cement plant on the island by 2030. However, the newly approved plans to build two new electrical transmission cables to Gotland are currently scheduled for completion in 2031. The cement plant is expected to require annual electricity requirements of up to 1.5TWh with a power requirement of up to 250MW when the CCS unit is completed.

The cement producer has welcomed the government’s upgrade plans so far but has impressed the urgency of its timeline to build a CCS unit at the Slite plant. It says it is currently considering investing around Euro850m on the project. If completed the CCS unit is expected to capture up to 1.8Mt/yr of CO₂. The company said that this corresponds to approximately 3% of Sweden's emissions annually.

UK: Cemex UK has completed upgrades of its Dove Holes, Selby and Bletchley depots in partnership with MLP Railway Maintenance. As a result of the upgrade, the Selby depot in North Yorkshire can now receive an increased number of wagons per train, and complete turnarounds more quickly. Meanwhile, the producer relayed two reception lines at the Dove Holes depot in Derbyshire and installed new walkways, CCTV and a waterproof display screen for offloading at the Bletchley depot in Buckinghamshire.

Cemex UK’s rail and sea manager Mark Grimshaw-Smith said “It’s important that we continue to invest in our railheads across the UK. This not only ensures that the safety and wellbeing of those who work on our sites is enhanced on an ongoing basis, but it also provides further resilience in the operation, transporting more materials by train and thus taking more trucks off the road.”

Germany: Holcim Deutschland has commenced a carbon capture trial at its 950,000t/yr Beckum cement plant in Beckum-Kollenbach, North Rhine-Westphalia. The trial will employ amine scrubbing technology to separate CO₂, which it will then seek to commercialise for other industrial uses. Holcim Deutschland's partners for the project are Technische Universität Berlin and construction engineering firm thyssenkrupp Uhde. The trial also has funding from the German government.

Bangladesh: Premier Cement Mills plans to install a new vertical roller mill at its West Mukterpur cement plant in Munshiganj. For this purpose, it secured a US$32.7m long-term loan from state-owned Infrastructure Development Company Limited (IDCOL). The New Nation newspaper has reported that IDCOL focuses on financing projects to increase energy efficiency, alongside the development of renewable energy.

US: 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."

UAE: Holcim subsidiary Lafarge Emirates Cement (LEC) has begun construction of a 10MW waste heat recovery (WHR) plant at its 3.2Mt/yr Fujairah cement plant. Supplier Engie Solutions says that it expects to commission the installation later in 2023. Trade Arabia News has reported that the equipment is based on a closed-loop organic Rankine cycle and will eliminate 29,000t/yr of CO₂ - 28% of the Fujairah cement plant's energy-related CO₂ emissions.

LEC general manager Olivier Milhaud said "Engie’s energy-as-a-service model means guaranteed energy savings and higher reliability and resilience, with no capital outlay and no need for additional staff." He continued "We are fully committed to the UAE’s sustainability goals, including the 2050 Net Zero vision."

Sinoma International Engineering was revealed this week as the winner of a contract to build a new production line at Southern Province Cement’s Jizan plant. The China-based engineering firm said that the US$330m contract was to build a full line, from limestone crushing to bagging, with an output of 5000t/day. The construction period is expected to take just over two years, suggesting a commissioning date in mid-2025 if work starts now. The project has been in the pipeline for a while with an announcement in mid-2021. It was previously reported that the new line is intended to replace the two existing production lines at the site once completed.

Other recent projects in the country include Yamama Cement’s plans to move its cement plant near Riyadh to a new location. Sinoma International Engineering was also selected as the main contractor in November 2022 for the US$220m project. The relocated line – using both old and new equipment – will have a production capacity of 10,000t/yr. Project duration was estimated at around two-and-a half years following financial contractual commitments. So the earliest this one might be completed is also mid-2025. Eastern Province Cement also started making moves to build a new major upgrade in March 2023 when it started the tendering process for a planned 10,000t/day production line at its Al Khursaniyah Plant. The intention is to replace some of the obsolete lines at the unit. The project dates back to 2015, when it was first announced.

The timing of these new projects is compelling given that sales by the local industry peaked in 2015. They declined in 2018 to a low of around 40Mt before stabilising at around 50Mt for the last three years. However, one trend to note is how clinker exports reached 7.1Mt in 2022, the highest figure in a decade, since export rules were relaxed in 2017. They have grown year-on-year since 2018 with the exception of 2020. Cement exports have been lower since 2013 hitting a high of 1.9Mt in 2019, although 2022 was nearly as good at 1.8Mt.

The other big news story from the local sector in 2023 was the US$37m fine that the General Authority for Competition (GAC) levied for price fixing in April 2023. 14 of the 17 main cement companies in the country were found to have broken local competition law following an investigation. Detail on specifically what happened is light, but the GAC said that it took exception to companies “controlling prices of commodities and services meant for sale by increasing, decreasing, fixing their prices or in any other manner detrimental to lawful competition.”

As ever with the Saudi construction market, government spending is expected to keep things buoyant. Although input and logistic costs have risen like everywhere else, energy costs have also risen. This, no doubt, is useful to a government planning on building a bunch of so-called ‘Giga’ projects. Local sales of cement may have dipped slightly in 2022 but building all these big new projects will require plenty of cement. A report by the SICO Bank in January 2023 forecast that local cement demand was expected to remain ‘flat’ in 2023 but that it would grow by 5% year-on-year in 2024. Interestingly, it added that demand from the tourism and exhibition sector would also fuel demand in the run-up to 2030 as various schemes connected to the ‘Giga’ projects reached fruition.

Each of the three projects detailed above are intended to replace existing capacity. This suggests that none of these companies expect the market to grow significantly anytime soon. These cement producers are likely to be focusing on improving efficiencies from their existing market share. Alongside this, exports of cement and clinker have grown, giving combined local and export sales that are similar to the market peak in 2015. Efficiency savings and adapting to a mature market appear to be the way forward for Saudi cement producers in the near-term.

India: UltraTech Cement has announced a plans to install a RotoDynamic Heater (RDH) supplied by Finland-based Coolbrook at one of its cement plants. The RDH uses renewably powered electrical heat, eliminating the need for cement fuels. UltraTech Cement will initially test the equipment in the drying of alternative fuel (AF) in its existing AF line.

UltraTech Cement managing director Kailash Jhanwar said “As a founding member of the Global Cement and Concrete Association (GCCA), we are committed to the sectoral aspiration of delivering net zero concrete by 2050. Towards this end, we are continuously striving to innovate at every stage of the whole life of concrete. Coolbrook’s RDH technology represents an exciting technological pathway that we believe has the potential to exponentially accelerate our progress towards full decarbonisation. Every megawatt of clean energy we add to our mix makes a big difference.”
