Peru: Grupo Gloria plans to invest US$100m in an upcoming lime plant in Lima. OneStone Consulting has reported that the plant will supply lime for Lima’s construction, agriculture and mining sectors.

Grupo Gloria subsidiary Cal & Cemento Sur already operates a five-kiln lime plant in Puno Region with five kilns, comprising three Maerz Parallel Flow Regeneration (PFR) vertical kilns and two horizontal kilns.

Australia: The Australian government’s ‘unwillingness’ to impose a carbon levy on imported cement, lime and clinker is threatening decarbonisation efforts and could cost up to 1400 jobs, according to the Financial Review.

The Cement Industry Federation, which represents local producers Adbri, Boral and Cement Australia, has said that the absence of a carbon levy on imports from countries with less robust climate commitments paved the way for the offshoring of local manufacturing, a process known as ‘carbon leakage’.

It said “Not addressing the issue of carbon leakage in a timely manner will be detrimental to Australian cement and lime manufacturing and could lead to the unnecessary loss of key Australian cement and lime facilities."

Imports currently account for over 40% of domestic clinker consumption and originate largely from southeast Asia. In 2023, an energy expert was appointed by the government to assess the feasibility of an Australian carbon border adjustment mechanism, with a final recommendation expected to be delivered in 2024. However, only an interim report was released in November 2024, with the final advice now reportedly due after the election in May 2025.

US: Carbon capture firm Nuada and lime producer MLC (formerly Mississippi Lime Company) have signed a memorandum of understanding to demonstrate net-zero lime production at MLC's Ste. Genevieve plant in Missouri. The partners aim to contribute to a reduction of the facility’s CO₂ emissions by 95%.

Nuada’s technology uses metal-organic frameworks as a solid sorbent alongside vacuum swing pressure adsorption, which utilises pressure rather than heat to separate CO₂ from flue gases.

Co-CEO Jose Casaban said "Our breakthrough in carbon capture technology sets a new standard for energy efficiency, paving the way for transformative decarbonisation in hard-to-abate sectors like lime manufacturing. Through this collaboration with MLC, we are driving the next generation of carbon capture forward, setting a new standard for emissions reduction and sustainability in the lime industry."

US: Researchers at UCLA's Institute for Carbon Management have developed a new method called ZeroCAL that could eliminate ‘nearly all’ of the carbon dioxide emissions from the process of cement production, according to the UCLA Newsroom. The team created a process using limestone and a water-based solution containing ethylenediaminetetraacetic acid. Through membrane nanofiltration and an electrochemical process, they produced calcium hydroxide.

To meet ZeroCAL’s water demand, the team suggests focusing on cement plants near coasts or rivers. The researchers are reportedly working with Ultratech Cement to build a demonstration plant that will produce ‘several’ tonnes of lime per day using the ZeroCAL process. Currently, the process requires more energy than traditional lime production methods, but ongoing research aims to reduce its energy consumption.

Gaurav Sant, director of the Institute and professor at UCLA Samueli School of Engineering, said “The ZeroCAL approach offers an elegant solution to eliminate carbon dioxide emissions associated with the process of cement production. First, it addresses the carbon emissions resulting from limestone’s decomposition while providing clean hydrogen and oxygen to heat the cement kiln. Second, it enables onsite decarbonisation while making use of existing kilns and limestone feedstocks without having to build separate carbon capture and storage facilities.”

CRH, formerly Cement Roadstone Holdings, announced this week that CEO Albert Manifold is retiring at the end of 2024. He will be replaced by current chief financial officer Jim Mintern in the role. Manifold will continue to work as an advisor to CRH in 2025. Manifold’s time at the head of CRH marks a decade of considerable change at the group. Crudely, CRH had a market capitalisation of US$19bn at the start of 2014 when Manifold became CEO. At the end of 2023 the group’s market capitalisation was US$50bn.

From a cement sector perspective the big events during Manifold’s tenure include CRH’s acquisition of assets around the world from the Lafarge-Holcim merger in 2015, the purchase of Ash Grove Cement in the US in 2018, the divestment of various businesses in emerging markets and the move of the company’s primary listing to the New York Stock Exchange in 2023. However, at the same time, CRH has been constantly sharpening its portfolio. So, for example, the group bought Germany-based lime and aggregates company Fels in 2017 only to later sell off its European lime business in 2023 and 2024. In the late 2010s the group sold off its US and Europe-based distribution businesses. Then, in 2022, it divested its Building Envelope business. Manifold was also the inaugural president of the Global Cement and Concrete Association (GCCA) when it formed in 2018.

Fairly or unfairly, CRH has given the sense over the last decade of often being ahead of the curve in following the cement markets. After it increased its portfolio when Lafarge and Holcim merged, it sold up relatively quickly in India and Brazil. Famously during an earnings call for CRH’s second quarter results in 2019, Manifold said that the group was prioritising its businesses in the developed world. CRH’s focus on the US in the late 2010s through the acquisition of Ash Grove Cement set it up well for the current strength of the cement market in North America, long before others joined the party. Another striking Manifold statement came at the company’s annual general meeting in 2023 when, in the run-up to the US listing move, he described his company as a ‘de facto’ American company.

Things that may have gone less well for Manifold on the cement side, that we know about, include CRH’s quiet attempt to divest its business in the Philippines in the late 2010s. The company wasn’t alone in trying through. Holcim publicly said that it had signed a deal to sell its local business in 2019 only to declare that it wasn’t happening the following year. Cemex is currently in the process of selling its subsidiary in the country, DMCI Holdings, but it hasn’t concluded yet. More recent acquisitions such as assets from Martin Marietta Materials in Texas in early 2024 and a majority stake in Adbri in Australia are clearly strategic and fit the definition of ‘bolt-on’ but they seem to lack the grand ambition of the earlier big deals.

Questions have also been asked about Manifold’s pay over the years. From 2016 onwards the Institutional Shareholder Services (ISS), for example, has repeatedly raised concerns about executive pay rises at CRH and recommended on occasion that shareholders reject them. Manifold became the highest paid head of an Irish public company and was reportedly the third highest paid CEO on the Financial Times Stock Exchange 100 Index (FTSE 100) in 2022. His response from one interview with the Irish Times newspaper in 2018 was simply: “I’m employed and paid very well to deliver shareholder returns.”

Looking back over the last decade, CRH was well placed to take advantage of the Lafarge-Holcim merger before Manifold started in 2014 but once he was in place it went for it and he led the charge. Yet, the Ash Grove Cement acquisition may prove to be the more momentous move given the current divergence of the European and North American markets. As readers may remember from the time, Summit Materials made a public counter offer but it was rebuffed. Albert Manifold was in charge of CRH and so he takes the credit. These are big shoes to fill. As Richie Boucher, the chair of CRH said in Manifold’s outgoing statement, “Under Albert’s leadership CRH has delivered superior growth and performance with consistently improving profitability, cash generation and returns.”

Europe: CRH has finalised the sale of its lime operations across Europe for US$1.1bn. The transaction concluded with the divestment of the group’s operations in Poland.

Australia: Calix has been awarded a US$10m grant from the Australian government’s Carbon Capture Technologies Program to build a commercial demonstration electric calciner for ‘near zero emissions’ lime and cement production. The grant covers up to 50% of the expenditure, contingent on meeting project milestones.

The project will utilise the Leilac technology to capture up to 20,000t/yr of CO₂ from the cement and lime manufacturing processes. The project will create two revenue streams via a ‘near zero emissions’ lime product, as well as up to 15,000t/yr of captured CO₂ being sold to the SM1 project for green methanol production.

In the second phase of the project, production will be expanded to include the processing of cement raw meal to a ‘near zero emissions’ clinker product, with captured CO₂ supplied for use.

Peru: The Gloria Group is set to expand its operations with a new lime plant in Lima's industrial zone, according to CE NoticiasFinancieras. This development is promoted by the group’s cement, concrete and lime subsidiary Cemento Yura. The proposed plant, will have a production capacity of over 350,000t/yr and will serve both domestic and export markets. Currently, the group operates Cal y Cementos Sur (Calcesur), which produces quicklime and hydrated lime in Juliaca with a capacity of 1Mt/yr. With lime demand rising, particularly from the mining and construction sectors, Gloria Group is also considering further plant projects.

The company is reportedly confident that the procedures for obtaining operating permits for new projects in the mining sector will be expedited in order to stimulate the demand for lime. It also did not rule out the implementation of new plants.

Zimbabwe: Khayah Cement has reported a significant increase in sales volumes across its operations for the year ending 31 December 2023. Dry mortar product sales volumes surged by 153%, bolstered by the demand for the Supagrow agricultural lime range within the government's Pfumvudza agriculture programme, absorbing 0.34Mt during the period. The firm's cement business also saw a 34% year-on-year increase in sales volumes following the installation of a vertical cement mill in the third quarter of 2022.

Despite challenges such as power quality issues and equipment breakdowns impacting production, bulk cement volumes grew from 1% to 4% during the period. However, clinker production volumes fell by 21%, mainly due to the mothballing of the kiln in the last half of 2023.

The company said “A total of 1000 hours were lost as a result of the unplanned breakdowns which in turn impacted negatively on both clinker, cement production and sales volumes and with it profits and cash generation.”

UK/Poland: SigmaRoc announced it has entered a share purchase agreement and exercised a call option to acquire the Polish lime operations of CRH. The deal, valued at €100m for deferred consideration, follows SigmaRoc's acquisition of CRH's lime operations in Germany, Ireland, the Czech Republic and the UK. The acquisition includes two production sites in Kujawy and Sitkowka, along with an associated distribution network. Completion is contingent upon clearance from the Polish Competition Office, anticipated by the end of September 2024.

SigmaRoc said it is ‘pleased’ with the progress to date on the integration of the German, Czech, Irish and UK entities, and will provide a further update alongside its interim results for the period ending on 30 June 2024.
