UAE: India-based UltraTech Cement has revised its former offer to acquire a 32% stake in RAK White Cement.The group told investors on 25 June 2024 that it is now seeking to acquire a 25% stake. The acceptance period for its previous offer elapsed on 24 June 2024.

The Hillhead Quarrying, Construction and Recycling Show is in full flow this week, taking place near Buxton in Derbyshire. As one delegate marvelled on the panoramic minibus journey down to the quarry, “It’s like a music festival without the music and… other stuff.” Indeed. Of course what one doesn’t find at Glastonbury and the like is a near comprehensive range of suppliers, over 600 of them, to the industry all in one place… in a quarry! Where else can one get up close and see the new hydrogen-powered generators and excavating vehicles that are being piloted? The official attendance figures don’t get released until after the event but on the ground it looks as busy as ever. It’s truly the place to be this week.

The show gives us a reason to take a look at the UK cement sector. Like many other countries around the world it is an election year in the UK, with a General Election scheduled for 4 July 2024. The result of this should determine the next Prime Minister and the ruling party. So, naturally, the MPA, the trade association for the aggregates, asphalt, cement, concrete, dimension stone, lime, mortar and industrial sand industries, is taking the opportunity to remind the political parties what its priorities are. The quick version is: support for decarbonisation; a streamlined planning system; and better delivery of projects. This sounds familiar to priorities in other countries but one British spin on this includes the UK’s carbon border adjustment mechanism (CBAM).

Edwin Trout’s feature on the UK cement sector in the June 2024 issue of Global Cement Magazine presents a good overview of the last 12 months. The general UK economy has faced shocks in recent years such as Brexit, Covid-19 and the war in Ukraine. However, this has been further compounded by a downturn and high interest rates since late 2022 when the then Prime Minister Liz Truss caused market turbulence in the wake of a badly received government financial statement. As Trout relates, sales of heavy building materials have been in relative decline since mid-2022 with more of the same expected in 2024. Production of cement in 2023 is currently uncertain given the reporting time lag from the MPA but up until 2022 domestic cement sales fell somewhat but imports grew. This has created a situation where overall cement sales in 2022 were 12Mt, not far behind the annual level in the early 2000s. However, the share of imports has nearly doubled since then. More recent MPA data on mortar and ready-mixed concrete sales throughout the first nine months of 2023 suggest that market activity has decreased and poor weather at the start of 2024 looks set to have made this worse.

Despite the apparent slowdown in building materials sales the cement companies have been conducting smaller-scale maintenance and upgrade projects at their facilities and supply chain schemes such as the cement storage unit for deep sea shipping lines that Aggregate Industries said in February 2024 it was going to build at the Port of Southampton. The news the cement companies want to show off has been a steady stream of information about ongoing decarbonisation projects in the cement sector. C-Capture started a carbon capture trial at Heidelberg Materials’ Ketton cement works in Rutland in May 2024, Capsol Technologies said in March 2024 that it had been selected to conduct a study on its carbon capture technology at Aggregate Industries Cauldon cement plant in Staffordshire, Heidelberg Materials' Ribblesdale cement plant in Lancashire announced in March 2024 that it was taking part in a study to assess the use of ammonia as a hydrogen source for fuelling cement kilns and Heidelberg Materials awarded Japan-based Mitsubishi Heavy Industries (MHI) a front end engineering design contract for a carbon capture installation at its Padeswood cement plant in Flintshire in February 2024. Finally, on the divestment front, CRH completed the sale of its UK-based lime business to SigmaRoc for €155m in March 2024. The business operates from sites in Tunstead and Hindlow with five permitted lime kilns.

That’s it for this short recap on the UK for now. For a longer look at the UK cement sector read Edwin Trout’s feature in June 2024 issue of Global Cement Magazine.

Hillhead 2024 runs until 27 June 2024

UK: MQP (Midland Quarry Products) has appointed Andrew Boileau as its managing director. He succeeds Rick Green, who has retired after a 40-year career in the industry, taking responsibility for MQP’s three quarries and 10 asphalt plants located across the Midlands. MQP is a subsidiary of Heidelberg Materials.

Boileau previously worked as the Programme Director for STARK Building Materials. He has also held various senior roles at Saint-Gobain, including Managing Director of Gibbs and Dandy.

Türkiye: Çimsa has secured a US$26.7m loan from the European Bank for Reconstruction and Development (EBRD). The bank says that the loans will finance decarbonisation projects, including the establishment of waste heat recovery (WHR) and solar power units.

Çimsa CEO Umut Zenar said, "We are determined to advance our sustainability goals and take important steps in our energy efficiency and decarbonisation efforts. This collaboration with the EBRD represents a significant milestone in our journey towards a greener future. We are proud to be the first cement company in Türkiye to receive this type of financing from the EBRD, reflecting our commitment to leading the industry in sustainability initiatives.”

The EBRD expects Türkiye to require US$10bn worth of investments up to 2030 to be on track for its target of net zero CO₂ emissions by 2053.

US: A team at the University of Princeton has developed a new alternative cement using oyster shells. The team says that the oyster shells provide calcium carbonate in the form of aragonite, along with biopolymers. Together, these raise the resulting cement’s crack resistance by 19% and its ductility by 17% compared with ordinary Portland cement (OPC).

Team leader Reza Moini said “Our bio-inspired approach is not to simply mimic nature’s microstructure, but to learn from the underlying principles and use that to inform the engineering of human-made materials. One of the key mechanisms that makes a nacreous shell tough is the sliding of the tablet at the nanometer level. Here, we focus on the mechanism of tablet sliding by engineering the built-in tabulated structure of cement paste in balance with the properties of the polymer and the interface between them. In other words, we intentionally engineer defects in the brittle materials as a way to make them stronger by design.“

India: JK Cement has inaugurated its 2Mt/yr Prayagraj grinding plant in Uttar Pradesh. The Economic Times newspaper has reported that the plant raises JK Cement’s cement production capacity by 9% to 24Mt/yr.

India: Ambuja Cements and Ravi Sanghi plan to launch an offer for sale of a stake in Sanghi Industries. The Times of India newspaper has reported that Ambuja Cements will offer 2.4% of shares and Ravi Sanghi will offer 1.2%, giving a total offer of 3.6%. Following the completion of the intended sale, the companies’ combined stake in Sanghi Industries will drop to 75%, in line with shareholding rules for promoters.

US: Heidelberg Materials has successfully converted its cement plant in Speed, Indiana, into a slag grinding facility. The facility ceased Portland cement production in 2023 following the opening of a new plant in Mitchell, Indiana, and now produces slag cement using domestically sourced slag granules. The Speed site has a grinding capacity of over 400,000t/yr and also functions as a distribution hub for the Mitchell plant's cement and other products.

Italy/UK: UK-based carbon capture technology provider Nuada has launched carbon capture trials with Buzzi at its cement facility in Monselice, aiming to accelerate the decarbonisation of the cement industry. The MOF-based VPSA carbon capture plant is now fully operational, capturing 1t/day of CO₂ directly from the facility's stack.

Nuada posted on LinkedIn “Nuada's carbon capture solution is the most energy-efficient developed to date, redefining the decarbonisation landscape for hard-to-abate sectors like cement. Together with Buzzi, we are showcasing the future of carbon capture in the cement industry.”

Switzerland: Neustark has raised US$69m in a growth equity round to scale up its carbon dioxide removal technology. The funding, led by Decarbonisation Partners—a collaboration between BlackRock and Temasek—will support Neustark's aim to permanently remove 1Mt of CO₂ by 2030. Climate tech growth investor Blume Equity also joined the round, alongside existing backers Holcim, Siemens Financial Services, Verve Ventures and ACE Ventures.

Neustark has developed a technology that captures biogenic CO₂ at its source and utilises it in building materials through an accelerated mineralisation process. This method is currently applied at 19 carbon capture and storage plants in Switzerland, Austria, Liechtenstein and Germany, with 40 more under construction across Europe.

Johannes Tiefenthaler, co-CEO and founder at Neustark, said “We turn the world’s largest waste stream, demolition concrete, into a carbon sink. In the past year, we have already deployed our unique solution at 19 sites. This growth investment will take us into the next exciting phase of our mission, helping us to further scale our impact across Europe, enter new markets in North America and Asia Pacific, and develop new solutions to store even more CO₂ in mineral waste streams.”
