Typical! We published a cement sector news review for 2024 in the December 2024 issue of Global Cement Magazine and a load of big important events happened afterwards. So, here is a roundup of some of the major stories that have taken place in the last two months of the year.

The TL:DR (too long; didn't read) version of ‘Global Cement News in 2024’ was: focus on the US market by the multinationals; cement joining the emissions trading scheme in China as the world’s largest market stagnates; continued rivalry between UltraTech Cement and Adani Group in India as that sector grows; markets in the Middle East and North Africa adjusting to higher exports; the drawn out divestment of InterCement in Brazil; lots of new plants in Sub-Saharan Africa reflecting demographic trends; and an emphasis on construction and demolition materials in Europe but one on aggregates in North America.

However, from November 2024 onwards… Donald Trump was re-elected as President in the US, Quikrete put in an US$11.5bn deal to buy Summit Materials, the United Nations Climate Change Conference (COP29) in Azerbaijan ended in acrimony, Gautam Adani was accused of fraud by a US court and Huaxin Cement said it was buying Holcim’s majority stake in Lafarge Africa for US$1bn. These have all been covered in previous editions of Global Cement Weekly. Check them out for more information. One can tell it’s been a busy tail-end to the year though when a US$600m agreement by Heidelberg Materials North America to buy Giant Cement Holding did not make the top five, admittedly selective, noteworthy news stories of the last two months of 2024. These stories also, roughly, followed the trends highlighted in the ‘Global Cement News in 2024’ article.

To reflect on the Adani story a few weeks later, nothing much seems to have occurred. Yet. The share price of various Adani Group companies fell when the US authorities made the announcement in late November 2024 but they have mostly regained much of their value since then. The consensus by Reuters, this week, was that the US prosecutors have a strong case backed up by documentation but extradition seems unlikely. Adani himself has made public appearances in India since the allegations surfaced. One minor consequence has been that Gautam Adani exited the US$100bn Bloomberg Billionaires Index in 2024. This is likely to have been caused, in part at least, by the allegations from Hindenburg Research in 2023 and the current legal problems from the US bringing down share prices. On the cement side of Adani Group it appears to have been business as usual so far. A large-scale investment in Rajasthan was announced in December 2024 and, this week, plans to merge subsidiaries Sanghi Industries and Penna Cement with Ambuja Cements were disclosed.

Another general trend that we haven’t covered much online have been changes in the Australian market. Last week, Cement Australia, a joint venture between Heidelberg Materials Australia and Holcim Australia, said it was acquiring the cementitious division of the Buckeridge Group of Companies (BGC) for US$800m. This follows CRH’s purchase of a majority stake in AdBri that was approved by the latter’s shareholders over the summer. Around the same time, Seven Group Holdings completed its acquisition of the remaining 28% stake in Boral that it did not already own. For more on the situation in Australia and New Zealand read the article in the January 2025 issue of Global Cement Magazine.

That’s it for 2024. Unless another massive news story in the cement sector gets announced in the next week-and-a-half.

Global Cement Weekly will return on Wednesday 8 January 2025

Australia: Cement Australia, a joint venture between Heidelberg Materials Australia and Holcim Australia, will acquire the cementitious division of the Buckeridge Group of Companies (BGC) in Perth for US$800m, according to The Australian. The acquisition includes a cement grinding unit with ‘significant’ capacities, along with operations in cement, concrete, quarry, asphalt, transport and a materials technology centre. Cement Australia reportedly ‘fended off competition’ from Boral, Adbri and Mass Group in the process. BGC has stated that it retains a ‘significant’ business with about 1000 employees across its other sectors. The acquisition remains subject to regulatory approval, but is expected to close in the second half of 2025.

Australia: Woodside Energy and Cemex have invested US$6.7m in Melbourne-based KC8 Capture Technologies to support its efforts in achieving net zero emissions via carbon capture and storage.

KC8 is partnering with Cement Australia to construct a commercial demonstration plant in Gladstone, Queensland, aiming to capture 15t/day of CO₂. A partnership with Cemex aims to capture over 100t/day of CO₂ at one of its major plants. Additionally, KC8 plans a commercial pilot at the US Department of Energy’s National Carbon Capture Centre to capture 10-15t/day of CO₂ from natural gas combustion flue gas. The initiative has also secured US$6m from Low Emission Technology Australia and US$11.26m from the US government.

Executive director Greg Ross said "The funds will be used to expand KC8’s team and expedite deployment of its technology into hard-to-abate industries, such as cement – through a number of key projects."

Australia: Cement Australia has received a US$34.4m federal grant for a kiln upgrade to its Railton cement plant in Tasmania. The upgrade will allow the plant to raise its alternative fuels substitution rate. The project is funded by the government’s Powering the Regions initiative, with total investments valued at US$215m.

Australian Minister for Climate Change and Energy Chris Bowen said “This US$215m investment in Australia’s hard-to-abate manufacturing and mining facilities is about securing the future of high-quality, low-emissions products made right here. Northern Tasmania, Central Queensland and Western Australia have been industrial powerhouses for generations, and the government is ensuring that continues. As global markets change rapidly, we’re supporting Australian industry to not only survive but thrive with our world-class products that support regional jobs across the country.”

Australia: Cement Australia has signed a new three-year rail haulage agreement with Pacific National to transport shipping containers of cement, sand, fly ash, slag and lime. This will also includes the interstate and inter-city transport of cement and supplementary cementitious materials between large cities and throughout North Queensland. Cement Australia and Pacific National have a partnership that dates back over five years.

Pacific National is Australia’s largest private rail freight operator.

Australia: Cement Australia has commemorated the 100th anniversary of the start of operations at its Railton cement plant in Tasmania with a centenary dinner.

Production manager Garry Bissett said "When it opened up in 1923, they built the small kiln, and it was only capable of cement production of 25,000t/yr; now we're producing 1.4Mt/yr." He added that the workforce has fallen to less than half of its original size of 300 people, to 140. Bissett concluded "We're doing some major work, with a lot of capital upgrades in the near future."

Australia: The Australian government’s Department of Climate Change is receiving public comments on Cement Australia subsidiary Cornwall Coal’s plans to open a new coal mine in Tasmania’s Fingal Valley, near St Mary’s. Local press has reported that the proposed site will operate across three open pits, with a total area of 26ha. The mine will replace the company’s nearby Cullenswood coal mine when it runs out of coal later in 2023, and will operate until 2026 or 2027. Cornwall Coal’s Tasmanian operations currently supply coal for Cement Australia’s Railton cement plant, as well as other local industrial sites.

Under Cornwall Coal’s proposals, the company will build travel culverts for local wildlife, and assist in relocating animals currently occupying the site. Tasmanian devils and two species of quoll – all endangered – live on the land in question.

Mick Tucker, head of Break O’Day Municipality Council, said that the municipality currently depends on Cornwall Coal’s operations for 60 – 80 jobs. He said that the company’s plans have strong support in the local community.

In Australia and New Zealand, four producers operate a total of six integrated cement plants, with another 13 grinding plants situated in Australia. This relatively small regional cement industry has been on a decades-long trajectory towards ever-greater sustainability – hastened by some notable developments in recent weeks.

Oceania is among the regions most exposed to the impacts of climate change. In Australia, which ranked 16th on the GermanWatch Global Climate Risk Index 2021, destructive changes are already playing out in diverse ways.¹ Boral reported 'significant disruption' to its operations in New South Wales and southeast Queensland due to wet weather earlier in 2022. This time, the operational impact was US$17.1m; in future, such events are expected to come more often and at a higher cost.

Both the Australian cement industry and the sole New Zealand cement producer, Golden Bay Cement, have strategies aimed at restricting climate change to below the 2° scenario. Golden Bay Cement, which reduced its total CO₂ emissions by 12% over the four-year period between its 2018 and 2022 financial years, aims to achieve a 30% reduction by 2030 from the same baseline. The Australian Cement Industry Federation (CIF)'s 2050 net zero cement and concrete production roadmap consists of the following pathways: alternative cements – 7%; green hydrogen and alternative fuels substitution – 6%; carbon capture – 33%; renewable energy, transport and construction innovations – 35% and alternative concretes – 13%, with the remaining 6% accounted for by the recarbonation of set concrete.

Australia produces 5.2Mt/yr of clinker, with specific CO₂ emissions of 791kg/t of clinker, 4% below the global average of 824kg/t.² Calcination generates 55% of cement’s CO₂ emissions in the country, and fuel combustion 26%. Of the remainder, electricity (comprising 21% renewables) accounted for 12%, and distribution 7%. Australian cement production has a clinker factor of 84%, which the industry aims to reduce to 70% by 2030 and 60% by 2050. In New Zealand, Golden Bay Cement's main cement, EverSure general-purpose cement, generates CO₂ at 732kg/t of product.³ It has a clinker factor of 91%, and also contains 4% gypsum and 5% added limestone.

Alternative raw materials

Currently, Australian cement grinding mills process 3.3Mt/yr of fly ash and ground granulated blast furnace slag (GGBFS). In Southern Australia, Hallett Group plans to commission its upcoming US$13.4m Port Augusta slag cement grinding plant in 2023. The plant will use local GGBFS from refineries in nearby Port Pirie and Whyalla, and fly ash from the site of the former Port Augusta power plant, as well as being 100% renewably powered. Upon commissioning, the facility will eliminate regional CO₂ emissions of 300,000t/yr, subsequently rising to 1Mt/yr following planned expansions. Elsewhere, an Australian importer holds an exclusive licencing agreement for UK-based Innovative Ash Solutions' novel air pollution control residue (APCR)-based supplementary cementitious material, an alternative to pulverised fly ash (PFA), while Australian Graphene producer First Graphene is involved in a UK project to develop reduced-CO₂ graphene-enhanced cement.

Golden Bay Cement is investigating the introduction of New Zealand's abundant volcanic ash in its cement production.

Fuels and more

Alternative fuel (AF) substitution in Australian cement production surpassed 18% in 2020, and is set to rise to 30% by 2030 and 50% by 2050, or 60% including 10% green hydrogen. In its recent report on Australian cement industry decarbonisation, the German Cement Works Association (VDZ) noted the difficulty that Australia's cement plants face in competing against landfill sites for waste streams. It described current policy as inadequate to incentivise AF use.

Cement producer Adbri is among eight members of an all-Australian consortium currently building a green hydrogen plant at AGL Energy’s Torrens Island gas-fired power plant in South Australia.

Across the Tasman Sea, Golden Bay Cement expects to attain a 60% AF substitution rate through on-going developments in its use of waste tyres and construction wood waste at its Portland cement plant in Northland. The producer will launch its new EcoSure reduced-CO₂ (699kg/t) general-purpose cement in November 2022. In developing EcoSure cement, it co-processed 80,000t of waste, including 3m waste tyres. The company says that this has helped in its efforts to manage its costs amid high coal prices.

Carbon capture

As the largest single contributor in Australia's cement decarbonisation pathway, carbon capture is now beginning to realise its potential. Boral and carbon capture specialist Calix are due to complete a feasibility study for a commercial-scale carbon capture pilot at the Berrima, New South Wales, cement plant in June 2023.

At Cement Australia's Gladstone, Queensland, cement plant, carbon capture is set to combine with green hydrocarbon production in a US$150m circular carbon methanol production facility supplied by Mitsubishi Gas Chemical Company. From its commissioning in mid-2028, the installation will use the Gladstone plant's captured CO₂ emissions and locally sourced green hydrogen to produce 100,000t/yr of methanol.

More Australian cement plant carbon capture installations may be in the offing. Heidelberg Materials, joint parent company of Cement Australia, obtained an indefinite global licence to Calix's LEILAC technology on 28 October 2022. The Germany-based group said that the method offers effective capture with minimal operational impact.

Cement Australia said “The Gladstone region is the ideal location for growing a diverse green hydrogen sector, with abundant renewable energy sources, existing infrastructure, including port facilities, and a highly skilled workforce." It added "The green hydrogen economy is a priority for the Queensland government under the Queensland Hydrogen Industry Strategy.”

Logistics

Australian and New Zealand cement facilities' remoteness makes logistics an important area of CO₂ emissions reduction. In Australia, cement production uses a 60:40 mix of Australian and imported clinker, while imported cement accounts for 5 – 10% of local cement sales of 11.7Mt/yr.

Fremantle Ports recently broke ground on construction of its US$35.1m Kwinana, Western Australia, clinker terminal. It will supply clinker to grinding plants in the state from its commissioning in 2024. Besides increasing the speed and safety of cement production, the state government said that the facility presents 'very significant environmental benefits.'

Conclusion

Antipodean cement production is undergoing a sustainability transformation, characterised by international collaboration and alliances across industries. The current structure of industrial and energy policy makes it an uphill journey, but for Australia and New Zealand's innovating cement industries, clear goals are in sight and ever nearer within reach.

Australia: Cement Australia’s Gladstone cement plant in Queensland will host a study of methanol production from green hydrogen and captured CO₂. Japan-based Mitsubishi Gas Chemical Company will supply its green methanol production technology, while hydrogen and oxygen feedstocks will be sourced locally. Cement Australia and Mitsubishi Gas Chemical Company will collaborate on commercialisation of their green methanol. Cement Australia said that carbon capture and its utilisation in value added products is a strategic pillar of the company’s decarbonisation roadmap.

Australia: The Queensland Supreme Court has ruled that Wagners must meet lower prices offered by a competitor in the market in its cement supply contract with Boral. Wagners suspended its supply of cement products to Boral for six months in early 2019 when Boral said it found cheaper cement from Cement Australia, according to the Australian newspaper. However, the court found that an October 2019 pricing notice for cheaper supplies from Cement Australia was ‘valid and effective’. Boral will continue buying cement from Wagners until 2031.
