Taiwan Cement said this week that it is aiming for cement to account for less than half of its sales by 2025. At the annual shareholders’ meeting chair Nelson Chang defended the cement sector as a core business but said that the company was expanding more into the green energy sector through its energy storage and vehicle charging lines. Chang directly linked the strategy to growing carbon taxes around the world, such as the European Union Emissions Trading Scheme, where the carbon price has been occasionally close to pushing past Euro100/t since early 2022. Taiwan Cement formed a joint venture with Türkiye-based Oyak Group in 2018 that runs Cimpor in Portugal.

Taiwan Cement’s plan to decrease its reliance on cement is becoming a familiar one. Holcim notably revealed in 2021 that it was growing its light building materials division. Its cement division represented 60% of sales in 2020 with concrete and aggregates making up most of the rest to 92% and the remaining 8% on other products including light building materials. This started to change with the acquisition of roofing and building envelope producer Firestone Building Products in 2021. Other similar acquisitions have followed. Holcim’s current target is to grow the Solutions & Products division to around 30% by 2025, with cement reduced to somewhere between a third and half of sales. Earlier this year Japan-based Taiheiyo Cement said it was doing a similar thing as part of its medium-term strategy to 2035. In its case cement represented 70% of its sales in 2022 but it is now aiming to reduce this to 65% by 2025 and 50% by 2035.

A common pattern for the business composition of European cement companies is a mixture of heavy building materials made up of cement, concrete and aggregate. However, not every cement company follows the same route. Some cement companies are simply parts of larger conglomerates. UltraTech Cement, for example, is mostly just a cement company. However, it is also part of Aditya Birla Group, which runs a wide range of industries including chemicals, textiles, financial services, telecoms, mining and more. Depending on how one looks at it, UltraTech Cement’s cement business ratio is large or Aditya Birla Group’s ratio is small. Siam Cement Group (SCG) in Thailand is another example of a cement producer operated by a conglomerate with other major businesses.

A different approach that some cement producers take is to mix cement production with complimentary businesses outside of heavy building materials. A good example of this is Votorantim Cement in Brazil, which manufactures cement and steel. Companhia Siderúrgica Nacional (CSN) is another Brazil-based cement producer that is also well known for steel production. Adani Group in India, meanwhile, was well known for logistics, power generation and airports before it purchased Ambuja Cements and ACC from Holcim in 2022.

The driver for cement companies looking to reduce cement as a proportion of their businesses has varied between the three examples presented above. Holcim’s approach has been in response to growing European carbon costs but it also fits with a general desire to broaden its business as the company has sought to reshape itself following the merger between Lafarge and Holcim. Taiheiyo Cement’s plans also have a sustainability angle but the Japanese market has been in slow decline since the 1990s and this has been made worse by the spike in energy prices since 2022. Investing in new businesses makes sense for either of these reasons. Lastly, Taiwan Cement says it is taking action in response to carbon prices around the world. However, its proximity to many other large-scale producers in the Far East may also be a factor. Whether more companies follow suit and also start to reduce the ratio of their cement businesses remains to be seen. Yet, mounting carbon taxes and global production overcapacity look set to make more of the larger cement producers consider their options in certain places.

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.

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 two largest cement producers in Japan released their results for their 2023 financial years this week. Much like manufacturers elsewhere in the world they reported mounting sales revenues, but they also noted losses. Input prices such as coal rose in 2022 and these were passed on to consumers in the form of higher prices. However, this was insufficient to stop them making a loss.

In the case of Taiheiyo Cement, its domestic sales volumes of cement remained stable at 13.4Mt in the year to 31 March 2023. It made a loss at home in Japan but still reported a profit in its overseas businesses, despite export volumes falling by 41% year-on-year to 2.44Mt. The group also noted delays at construction sites due to a lack of workers. Recent domestic developments for Taiheiyo include an agreement in October 2022 to buy the cement business of chemicals company Denka. Outside of Japan, in China, the group suspended the production and sale of cement from its Jiangnan-Onoda Cement subsidiary in February 2023 citing a 'tougher competitive environment,' although it justified this decision as part of its strategy to refocus on Southeast Asia. Then, in late April 2023, the company was forced to stop its proposed acquisition of the Tehachapi cement plant in the US due to an inability to obtain regulatory approval.

Sumitomo Osaka reported a similar situation, with cement sales volumes also down year-on-year. Again, cement price increases were unable to catch coal prices made worse by negative currency exchange effects. Having got the bad news out of the way, it then it took the opportunity to outline its medium term strategy to 2035. It said that becoming carbon neutral was the key to this. In its 2022 financial year cement accounted for around 70% of total sales. However, it is now aiming to reduce this to 65% by 2025 and 50% by 2035. If this sounds familiar this is because it is similar to what Holcim is doing with its growing light building materials division and its diversification away from the heavy building materials trio of cement, concrete and aggregates. Sumitomo Osaka plans to invest over US$3.5bn towards this goal by developing its presence in the semiconductors sector, building its business in Australia and starting new ventures in decarbonisation.

Of the other cement producers, Tokuyama Corporation said in late April 2023 that it was considering suspending operation of one of the three kilns at its 4.54Mt/yr Nanyo cement plant as part of measures to strengthen profitability. It reported a growing loss for the current financial year that it blamed on raw material and fuel costs. Mitsubishi Materials and Ube Industries formed their merged cement businesses in April 2022 known as Mitsubishi UBE Cement Corporation. Ube said, as part of its latest financial results, that, despite a gradual decrease in the domestic market, cement sales had remained stable but that the business was “heavily affected” by rising energy prices such as coal. It added that demand for cement and concrete remain strong in its overseas market in North America.

The Japanese cement market peaked in the 1990s. Domestic sales of cement in Japan have declined over the last decade, as can be seen in Graph 1 above, but at a slower rate. Exports rose to a peak of just under 12Mt in 2017 but have slipped a little since then. Data from the Japan Cement Association placed production at 53.2Mt in 2022 compared to 61.7Mt in 2013. This trend explains the move by the cement producers towards decarbonisation, offshoring, diversification and consolidation. The bump in fuel prices over the past year may have accelerated this process, as examples such as Taiheiyo Cement’s takeover of Denka and Sumitomo Osaka’s new business strategy suggest. The race continues to keep cement production profitable in a changing business environment.
