Taking a look at the most read news stories on the Global Cement website in 2022 reveals what readers have been interested in. The usual bias applies due to the prominence of countries where English is prevalent and there is a concentration on stories from earlier in the year. Yet, even with these constraints, key trends identified elsewhere emerge. Read the December 2022 issue of Global Cement Magazine for a roundup of what we think has been noteworthy.

Top 10 news stories on Global Cement website in 2022

1. Holcim receives bids for Ambuja Cements
2. JK Lakshmi Cement and TARA to launch limestone calcined clay cement production
3. Ramco Cements to commission new plant at Kurnool in February 2022
4. CalPortland to buy Redding cement plant from Martin Marietta
5. ACC launches Houses of Tomorrow in India
6. CRH exits Russian market
7. HeidelbergCement freezes investments in Russian operations
8. US facing cement shortage
9. HeidelbergCement, Holcim and Sabancı Holding are potential buyers for Sika’s US assets
10. Jaiprakash Associates seeking to sell all assets

The two large India-based acquisition and merger (M&A) stories are both present at early stages of their development. Firstly, Adani Group went on to buy Holcim’s two subsidiaries, Ambuja Cements and ACC, becoming the second largest cement producer in the country. Secondly, Jaiprakash Associates was reported to be in dire financial straits in the autumn and looking to sell off more assets. This came to pass in mid-December 2022 when Dalmia Cement (Bharat) reached a deal to buy Jaiprakash Associates’ cement assets for US$684m. Incidentally, Adani Group made the news this week when it published plans to suspend production at two of its newly acquired cement plants in Himachal Pradesh due to high freight rates. The state government responded with a court order requiring the cement producer to justify its actions that, in its view, would detrimentally affect the lives of many. While it seems unlikely that the plants will close permanently, this incident does demonstrate that Adani Group is starting to take action with its new cement business.

The other M&A story concerns cement companies buying assets outside of the standard cement, concrete and aggregates triad. Global Cement has covered this business shift increasingly since Holcim acquired Firestone Building Products in 2021. The story in 2022 that readers were interested in concerned potential buyers for Sika US, an admixture manufacturer. This one also has a sustainability angle because admixtures can be used to make cement and concrete more efficient in different ways. A more obvious example of cement production becoming more environmentally friendly was that of an India-based cement producer preparing to start production of limestone calcined clay cement (LC3). The increased production of blended cements around the world has been a big story in 2022, particularly in the US.

Cement shortages in parts of the US were a theme we picked up on a few times in 2022. Nationally it followed supply issues in the southwest in early 2021 that led Cemex to restart a mothballed kiln at a plant in Mexico with the express aim of serving the export market.

In April 2022 shortages were being reported on the other side of the country in Alabama and South Carolina. Ultimately this was blamed on labour and supply chain issues in the aftermath of the coronavirus shutdowns. The other big US story in 2022 was back in California where CalPortland agreed to buy the Redding cement plant from Martin Marietta. The subsidiary of Japan-based Taiheiyo Cement later struck a further deal to buy the Tehachapi plant, also from Martin Marietta, in August 2022. Both of these integrated plants were previously sold by Lehigh Hanson to Martin Marietta in 2021. In November 2022 Lehigh Hanson announced that its remaining integrated unit in California, the Permanente plant near Cupertino, was going to be transitioned to a distribution and quarry site.

Finally, the top news stories in 2022 where not immune to the effects of the Russian invasion of Ukraine. The big underlying narrative has been a jolt to global energy prices. What could be seen here though were the efforts of the multinational cement producers to limit their exposure to the market in Russia and any potential legal action. CRH led the exodus, although it had a relatively small business to offload. Heidelberg Materials froze its investments in its Russia-based subsidiary in March 2022. Holcim completed the divestment of its business to local management in mid-December 2022. Buzzi Unicem withdrew from any operational involvement with its subsidiary SLK Cement in May 2022.

US: Taiheiyo Cement subsidiary CalPortland has concluded a deal with Martin Marietta Materials for the acquisition of the latter's Tehachapi cement plant in California for US$250m. The deal also covers two business centres.

Taiheiyo Cement said "We expect the US cement business to continue to have strong demand from the private sector in view of projected economic growth and chronic housing shortages going forward. Additionally, we expect the infrastructure demands to accelerate as a result of the passing of the more than US$1tn infrastructure investment bill by the US Congress. Further, California is likely to have even greater growth because it will host the 2028 Los Angeles Olympics. The planned acquisition of Martin Marietta Materials' assets is intended to ensure that we capture this increased demand. It is an essential element in maximising our future corporate value."

CalPortland completed its acquisition of the Redding cement plant from Martin Marietta this week. As previously announced the transaction involved the integrated cement plant in northern California, related cement terminals and 14 ready mixed concrete (RMC) plants also in the state. However, CalPortland’s parent company Japan-based Taiheiyo Cement revealed this time round that it is considering buying the Tehachapi cement plant from Martin Marietta too. It says it has some sort of preferential purchase agreement in place, although a final decision is yet to be made.

If CalPortland and Taiheiyo Cement do end up buying the Tehachapi plant as well as Redding then it will mark a fairly quick turnaround of owners. HeidelbergCement subsidiary Lehigh Hanson announced that it was selling up assets in its US West region to Martin Marietta for US$2.3bn in May 2021. The deal was completed by October 2021. Then, CalPortland said it was buying the Redding plant in March 2022. From an outside perspective it was not clear what Martin Marietta might have had planned for its new assets. Over three quarters of Martin Marietta’s revenue in 2021 came from its Aggregates and RMC products. However, it is also a prominent regional US cement producer with two plants in Texas and two plants in California, along with associated terminals. So, building up its cement business in California didn’t seem unfeasible. Now, as can be seen, it is likely to be sticking to its primary focus of aggregates and RMC. It is also worth noting that California has some of the stricter CO₂ reduction policies in the US with a 40% reduction target for 2030 (compared to 1990 levels) and a local emissions trading scheme that started in 2013.

Looking at the local cement production base in California, the latest development with the former Lehigh Hanson plants shows the changing situation since the subsidiary of HeidelbergCement left the region. Beforehand, Cemex, Lehigh Hanson and CalPortland each had a similar clinker production capacity. Then, Martin Marietta took the lead and now CalPortland looks set to become the frontrunner if it buys Tehachapi. With the Redding deal completed it now operates three integrated cement plants in California and one in Arizona. Alongside this it runs 15 terminals in Alaska, Arizona, California, Nevada, Oregon and Washington – and – two terminals in Alberta and British Colombia in Canada. The Redding plant is also a distinctive addition to its portfolio as it is further north than the other clinker units.

United States Geological Survey (USGS) data shows that cement shipments to California grew by 5% from 10.05Mt in 2019 to 10.57Mt in 2021. So far in 2022, shipments to the state rose by 3.4% year-on-year to 3.56Mt for January to April 2022 compared to 3.44Mt in the same period in 2021. However, clinker production fell by 5% to 8.94Mt in 2021 from 9.45Mt in 2019. This trend seems to have continued into 2022 with a 9% fall to 2.54Mt for January to April 2022 compared to 2.81Mt in the same period in 2021. Despite this, California remained the second largest OPC and blended cement producer in the US in April 2022. In its Western US Regional Outlook in May 2022, the Portland Cement Association (PCA) forecast that the Pacific region of the US (including California) will experience flat growth in cement consumption in 2023 due to a slowdown in residential consumption. However, consumption is then expected to bounce back sharply in 2024 as the effects of the infrastructure bill take effect.

This suggests that CalPortland has picked an uncertain time to start buying cement plants in California. Yet only last year, in 2021, Cemex began restarting production at a previously mothballed cement plant in Mexico to supply the south-west US. Alongside all of this, environmental regulations are tightening. However, the key difference between Martin Marietta and CalPortland is that the latter is owned by Japan-based Taiheiyo Cement, which is more cement-focused than the aggregate and concrete oriented Martin Marietta. No doubt Taiheiyo Cement’s intention to become more international also played a part in its decision making. If CalPortland does decide to buy Tehachapi then this may give observers an idea of how much further its ambitions go.

US: CalPortland has appointed Hamed Maraghechi as its Director of the Central Research Laboratory. He will be based at the CalPortland Center of Technical Excellence in southern California where he will conduct new research and testing related to issues such as carbon reduction and sequestration to help the company achieve its commitment to lowering greenhouse gases. He will also oversee all advanced analytical services for customers and for internal operations, in this newly created position.

Maraghechi holds a PhD in Civil and Environmental Engineering with a materials focus from the Pennsylvania State University, a master’s degree in Civil and Environmental Engineering from the University of Hawaiʻi at Mānoa and a master’s degree in Polymer Engineering from the University of Tehran in Iran. He was most recently a senior scientist at Fortera working on the design and development of low CO₂ cement and concrete formulations. Prior to Fortera, he worked as a scientist at Boral IP Holdings and the École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland.

US: The Portland Cement Association (PCA) has received the 2022 Energy Star Partner of the Year award from the Environmental Protection Agency and the Department of Energy. This is the third year in a row that PCA has earned this award.

"We are proud to have won this award for the third consecutive year. This latest award confirms our commitment to reducing cement sector CO₂ emissions through longstanding, long-term efforts to improve energy efficiency," said Michael Ireland, president and chief executive officer of the PCA. "This award shows once again that the cement and concrete industries are leading the way toward a more sustainable future, even as demand for our products grows."

The 2022 Energy Star Partner of the Year Award follows the launch of PCA's Roadmap to Carbon Neutrality in October 2021. In addition to PCA's recognition, two member companies also earned awards. CalPortland and Cemex won Partner of the Year awards in the energy management category. This is the fifth year in a row that Cemex has won this award, and the 18th successive year for CalPortland.

US: CalPortland has converted production at the 1.3Mt/yr Mojave cement plant in California to its Advancement HS, a Portland limestone cement (PLC) product. The plant will reduce its CO₂ emissions by 10% on a per ton basis. The company said the move supported the Portland Cement Association’s Roadmap to Carbon Neutrality and the industry’s overall efforts to address climate change.

US: The Environmental Protection Agency (EPA) has awarded its Energy Star certification to cement plants belonging to two Titan America subsidiaries. Titan Florida’s Pennsuco, Florida, cement plant has secured its 14th consecutive Energy Star, while Roanoke Cement’s Troutville, Virginia, cement has secured its 15th consecutive Energy Star.

Other cement plants to receive Energy Stars in 2022 included two Argos USA plants (Calera, Alabama, and Harleyville, South Carolina), two GCC plants (Pueblo, Colorado, and Rapid City, South Dakota), Buzzi Unicem’s Chattanooga, Tennessee, plant and three plants in Arizona: CalPortland’s Rillito plant, Drake Cement’s Paulden plant and Salt River Materials Group’s Clarkdale plant.

US: The former Lehigh Hanson Redding cement plant is the subject of a new acquisition deal. Martin Marietta has now agreed to sell the plant, which is in California, and related cement terminals to CalPortland for US$250m. The deal also covers 14 ready-mix concrete locations. The parties have also established arrangements for any future agreement for the sale of Martin Marietta’s Tehachapi cement facility and its related cement distribution terminals. Martin Marietta acquired both plants from Lehigh Hanson in October 2021.

CalPortland’s parent company Taiheiyo Cement said that the acquisition will enable it to build a supply system to meet the growing demand for cement in northern California, Oregon and Nevada. It added that the Redding Plant is an important plant in northern California, which its expects can improve customer satisfaction through an investment to develop more efficient systems. The company concluded “As a result, we expect steady growth in revenue and profits for Taiheiyo Cement’s US cement and ready mixed concrete businesses, which in turn will contribute to the achievement of the medium-term management plan from fiscal years 2022 to 2024.”

Holcim Schweiz hit a milestone recently with the aerial drone programme at its Siggenthal cement plant. The project with Voliro, a Switzerland-based technology start-up, has started to use multi-rotor drones to conduct official measurement flights. They used them to take measurements to determine the steel wall thicknesses of the cement kiln and the cyclone preheater. The work has been part of Holcim’s ‘Plants of Tomorrow’ industrial automation plan with unmanned aerial vehicles (UAV). Key features of the particular drones being used are that they can be rotated around all axes by a special rotor system and can even fly upside down.

Holcim has been using drones in and around cement plants for a few years now. When it launched the Plants of Tomorrow plan in 2019, Switzerland-based drone supplier Flyability said that the cement company had chosen its Elios 2 model to perform confined space inspection. Earlier in 2017 another supplier, SenseFly, said that LafargeHolcim Tanzania had been using its fixed-wing products. Holcim is also far from alone in its use of drones. A few examples among many include Cemex USA’s work with Kespry earlier in 2021, HeidelbergCement’s work in North America and Germany in 2020 and 2021 and Votorantim’s testing at its Córdoba and Niebla plants in Spain back in late 2015. 

UAV usage by armed forces dates back to examples like unmanned incendiary balloons being deployed in the 19^th century to Azerbaijan’s reported decisive use of drones in its war against Armenia in late 2020. The current era of industrial UAVs began after 2000 when governments starting issuing civilian permits, miniaturisation occurred and improvements in cameras, sensors and computing power followed. For the mineral processing sector the trend started with drones being used for stockpile management and quarry surveying. At present this is the main area that UAVs are used for by the sector, often coupled with photogrammetry techniques. CalPortland’s Adam Chapman’s paper at the 2021 IEEE-IAS/PCA Virtual Cement Conference described one company’s use of UAVs in the cement industry since 2016, looking at licensing, cost, quality of data, drone technology, fleet management and field experiences.

More recently though, tests of drones used to survey cement plant buildings and structures have started being publicised such as Holcim’s work at Siggenthal. A presentation by consultant John Kline and Chris Place of Exelon Clearsight summarised the use of drones for structural inspection at cement plants at the Global CemProducer 3 webinar in January 2021. The key benefits they promoted of using an UAV in this way were: improved safety because workers have reduced risk from climbing, working at height or in confined spaces; less time to conduct a survey; higher resolution photographs and video; better coverage through grid method surveying; and an overall lower cost. However, on that last point, other commentators have noted that market-leading drones for surveying are relatively expensive and easy to damage. Drones have since been used to start going inside structures at cement plants with Kline demonstrating their use to inspect the condition of refractory within the cooler, kiln, pre-heater and cyclone of a production line at the Global CemProducer 2 webinar in July 2020. HeidelbergCement has also been doing similar things, with an inspection trial using a drone of the kiln at the Schelklingen plant in Germany during the 2021 maintenance shutdown period at the site.

So far the use of drones by the cement industry has mostly been in a surveying or inspection capacity. Given the short time that UAVs have been used like this there is likely to be scope for lots more development both within existing fields and new ones as the sector works out how best the technology can be used. One application we couldn’t find in the research for this short article was the use of drones for security and surveillance tasks at cement plants and quarries although this may be happening already. However, there could be a more active role for drones if or when a company finds a way for them to start making basic repairs or carrying out simple maintenance in those hard to reach areas that drones excel at accessing. Research examples exist of UAVs being used to spray concrete or repair materials onto minor defects in concrete structures. Yet considerable challenges face these kinds of applications such as the weight of a loaded multi-rotor drone or damage from rebound. Before we all get too worried about drones replacing our jobs though it is worth considering that Amazon’s plan to deliver packages by UAV was first announced in 2013 and it still hasn’t happened yet. It may yet, but for now in most situations humans remain cheaper and more practical than robots or drones.

North America: US-based CalPortland has become a corporate member of the Wildlife Habitat Council. The council manages habitats to support sustainable ecosystems and the communities surrounding them. The Japan-based Taiheiyo Cement subsidiary says that the move formalises its commitment to integrating biodiversity and conservation action into its sustainability efforts.

President and chief executive officer Allen Hamblen said "Our membership with the Wildlife Habitat Council provides a unique opportunity to take corporate sustainability goals and objectives and translate them into tangible, on-the-ground actions which ensure a sustainable environment for the next generation."
