China/Denmark: Denmark-based FLSmidth Cement has signed a licensing agreement with Sinoma International Intelligent Technology (IIT) covering the production and sale of QCX lab equipment in China. Cyril Leung, Country Head China – FLSmdith, said “The deal effectively provides us a new sales channel and represents our continued commitment to enhancing our services in the world’s largest cement market.”

All QCX equipment that FLSmidth Cement supplies outside of China will continue to be made in Brno, Czech Republic. Development and delivery of QCX software will remain in Denmark. FLSmidth noted that the agreement has no impact on the ongoing divestment of FLSmidth Cement.
FLSmidth Cement’s QCX lab equipment supports sampling, preparation and analysis. Products in the range include the QCX/RoboLab laboratory automation system, analysers, sample preparation products, quality control systems and laboratory software.

When we think about ‘up and coming’ regions for the global cement sector, Africa is high on many people’s lists. This is unsurprising given that Africa is the youngest continent on Earth, with a population set to boom to 2.5 billion by 2050 – or 1 in 4 of the global population for that year, according to the UN. This population, 1 billion higher than today, will drive rapid urbanisation. Cement capacities, currently around 350Mt/yr across the continent, will have to rise substantially to meet demand.

Filling part of this rise will be Amsons Group. This week it announced plans for a US$320m investment in a 1.6Mt/yr greenfield cement plant in Tanzania. It also promised a whopping US$400m to revamp Bamburi Cement in Kenya, should its existing US$180m bid for the Holcim subsidiary be accepted. Based on the numbers for Tanzania, this investment might be enough to take Bamburi Cement from 1.1Mt/yr to around 3Mt/yr, assuming similar project scope and equipment suppliers.

So, what is Amsons Group? Founded in 2000, Amsons is a Tanzania-based conglomerate with interests in construction, transport, flour, container depots, cement and concrete. It already operates Camel Cement, a grinding plant, in the Mbagala suburb of Dar es Salaam and it owns a 65% stake in the 1.1Mt/yr integrated Mbeya Cement plant, which it bought from Holcim in September 2023. The group’s website states that it emphasises local production of materials to reduce the nation’s reliance on imports. A greenfield cement plant fits right into that philosophy.

Looking at recent market trends, we see some positive news for Amsons. In Tanzania, cement production rose by 6.2% to 8Mt in 2023, according to the country’s Ministry of Industry. This followed a 9.7% rise in the prior year. Data is so far lacking for 2024. To the north, cement consumption ramped up strongly in Kenya in the second half of 2023, following a less than stellar start to the year. Thanks to a particularly strong June to September period, consumption finally ended 2023 around 0.8% higher than the previous year, at 9.6Mt. However, consumption tailed off in the final quarter. Worse, the first four months of 2024 - the most recent data available from the Kenya National Bureau of Statistics - saw a 10% decline in cement consumption relative to the same period of 2023, falling to 2.6Mt/yr.

As Africa lacks cement capacity compared to other regions, it is important to highlight that Amsons’ new plants will have to take on not just existing capacity in East Africa, but countries that export to the continent too. Indeed, this week Pakistan, a long-time agitator of South African cement producers, reported a year-on-year rise in exports for October 2024. Exports rose to 4.36Mt, a 9% increase compared to 4Mt in October 2023. This news comes amid precipitously falling domestic demand within Pakistan, with September 2024 shipments down by 22% year-on-year. It is also worth noting that Tanzania itself exported around 1.1Mt of cement to Rwanda, Burundi, Malawi, the DRC and Zambia in 2023. This figure will likely be higher in 2024, given the February 2024 launch of Huaxin Cement Tanzania Maweni Company’s 1.3Mt/yr plant in Mavini, which has a focus on exports.

This apparent abundance of existing capacity, plus exposure to imports, would appear to give an investor like Amsons Group pause for thought. However, it has committed to a total investment of US$900m. This is not small change. If we add in the money it paid for Mbeya Cement in September 2023 – the amount was not disclosed – Amsons will likely shell out more than US$1bn in just a few years. It is going ‘all in’ to become, in the words of its Managing Director Edha Nahdi, “one of the largest cement manufacturers in Kenya and Tanzania by 2030.” It will be very interesting to follow it on its journey.

One unusual thing about coverage of cement in the media is the way that discussions often centre precisely on its absence – that is, on alternatives to cement. These alternatives boast unique chemistries and performance characteristics, but are all produced without Portland cement clinker. They are generally called ‘alternative cements,’ perhaps because ‘cement-free cement’ does not have such a commercially viable ring to it. This contradictory tendency reached a new high in the past week, with developments in alternative cement across Asia, Europe, the Middle East and North America. Together, they hint at a more diverse future for the ‘cement’ industry than the one we know today.

Asia

In Indonesia, Suvo Strategic Minerals has concluded tests with Makassar State University of a novel nickel-slag-based cement. Huadi Nickel-Alloy Indonesia supplied raw materials, and tests showed a seven-day compressive strength of 37.5MPa. Suvo Strategic Minerals says that a partnership with Huadi Nickel-Alloy Indonesia for commercial production is a likely next step.

Europe

Cement producer Mannok and minerals company Boliden partnered with the South Eastern Applied Materials (SEAM) research centre in Ireland to launch a project to develop supplementary cementitious materials (SCMs) from shale on 7 October 2024. The project will additionally investigate CO₂-curing of cement paste backfill for use in mines. Irish state-owned global commerce agency Enterprise Ireland has contributed €700,000 in funding.

UK-based SCM developer Karbonite expects to launch trial production of its olivine-based SCM with a concrete company in 2025. The start-up launched Karbonite Group Holding BV, with offices in the Netherlands, to facilitate this new phase. Karbonite’s SCM is activated at 750 – 850°C and sequesters CO₂ in the activation process, resulting in over 56% lower CO₂ emissions than ordinary Portland cement (OPC). Managing director Rajeev Sood told Global Cement that talks are already underway for subsequent expansions into the UAE and India.

Back in the UK, contractor John Sisk & Son has received €597,000 from national innovation agency Innovate UK. John Sisk & Son is testing fellow Ireland-based company Ecocem’s <25% clinker cement technology in concrete for use in its on-going construction of the Wembley Park mixed development in London.

At the same time, Innovate UK granted a further €3.23m to other companies for concrete decarbonisation. Recipients included a calcined clay being developed by Cemcor, an SCM being developed from electric arc furnace byproducts by Cocoon, a geopolymer cement technology being developed by EFC Green Concrete Technology UK and an initiative to develop alternative cement from recycled concrete fines at the Materials Processing Institute in Middlesbrough. Also included was the Skanska Costain Strabag joint venture, which is working on the London stretch of the upcoming HS2 railway. The joint venture, along with partners including cement producer Tarmac and construction chemicals company Sika UK, will test low-kaolinite London clay as a raw material with which to produce calcined clay as a cement substitute in concrete structures in HS2’s rail tunnels.

Middle East

Talks are underway between UK-based calcined clay producer Next Generation SCM and City Cement subsidiary Nizak Mining Company over the possible launch of a joint venture in Riyadh, Saudi Arabia. The joint venture would build a 350,000t/yr reduced-CO₂ concrete plant, which would use alternative cement based on Next Generation SCM’s calcined clay.

North America

Texas-based SCM developer Solidia Technologies recently patented its carbonatable calcium silicate-based alternative cement, which sequesters CO₂ as it cures.

Meanwhile, C-Crete Technologies made its first commercial pour of its granite-based cement-free concrete in New York, US. C-Crete Technologies says that the product offers cost and performance parity with conventional cement, with net zero CO₂ emissions. Its raw material is globally more abundant than the limestone used as a raw material for clinker. Other abundantly available feedstocks successfully deployed within C-Crete Technologies’ repertoire include basalt and zeolite.

Across New York State, in Binghamton, KLAW Industries has succeeded in replacing 20% of concrete’s cement content with its powdered glass-based SCM, Pantheon. KLAW Industries has delivered samples to local municipalities and the New York State Department of Transportation. Its success expands the discussion of possible circular cement ingredients from the industrial sphere into post-consumer resources.

In Calgary, Canada, a novel SCM has drawn attention from one of the major cement incumbents: Germany-based Heidelberg Materials. It invested in local construction and demolition materials (CDM)-based SCM developer EnviCore on 9 October 2024. The companies plan to build a pilot plant at an existing Heidelberg Materials CDM recycling centre.

Conclusion

Alternative cement developers are still finding the words to talk about their products. They may be more than ‘supplementary’ up to the point of entirely supplanting 100% of clinker. Product webpages offer ‘hydraulic binder,’ ‘pozzolan’ and even ‘cement.’ As alternative ‘cements’ are developed, they build on the work of pioneers like Joseph Aspdin and Louis Vicat. Start-ups and their backers are now reaching commercial offerings, on a similar-but-different footing to cement itself. None of these novel materials positions itself as the sole, last-minute ‘super sub’ in the construction sector’s confrontation with climate change. Rather, they are a package of solutions which can combine into a net zero-emissions heavy building materials offering, hopefully before 2050.

Related to this is the need for ‘technology neutral’ standards, as championed this week by the Alliance for Low-Carbon Cement and Concrete (ALCCC), along with 23 other European industry associations, civil society organisations and think tanks. The term may sound new, but the concept is critical to the eventual uptake of alternative cements: standards, the ALCCC says, should be purely performance-based. They ought not attempt to define what technology, for example cement clinker, makes a suitable building material. According to the ALCCC, Europe’s building materials standards are not technology neutral, but instead ‘gatekeep’ market access, to the benefit of conventional cement and the exclusion of ‘proven and scalable low-carbon products.’

At the same time, cement itself is changing. Market research from USD Analytics showed an anticipated 5% composite annual growth rate in blended cement sales between 2024 and 2032, more than doubling throughout the period from US$253bn to US$369bn. If you can’t beat it, blend with it!

For a further discussion of alternative cement and binders in Europe, see Global Cement’s interview with ALCCC co-ordinator Joren Verschaeve in the forthcoming November issue of Global Cement Magazine on 17 October 2024.

The mountainous eastern shore of the Adriatic Sea and its hinterlands in Europe’s Balkan Peninsula have one of the world’s highest densities of countries: six, across a broad equilateral triangle of 212,000km². All six states – Albania, Bosnia & Herzegovina, Kosovo, Montenegro, North Macedonia and Serbia – are historically characterised by political non-alignment, carrying over from the Cold War period, and all the more notable for the presence of the EU to the north (Croatia, Hungary and Romania) and east (Bulgaria and Greece).

A nine-plant, 9Mt/yr local cement sector serves the 16.8m-strong population of the unconsolidated ‘bloc.’ Albania has 2.8Mt/yr (31%), Serbia 2.7Mt/yr (30%), Bosnia & Herzegovina 1.6Mt/yr (18%), North Macedonia 1.4Mt/yr (15%) and Kosovo 500,000t/yr (6%), while Montenegro has no cement capacity – for now. Altogether, this gives this quarter of South East Europe a capacity per capita of 539kg/yr. The industry consists entirely of companies based outside of the region. Albania’s two plants are Lebanese and Greek-owned (by Seament Holding and Titan Cement Group respectively). Titan Cement Group also controls single-plant Kosovo and North Macedonia, and competes in the Serbian cement industry alongside larger and smaller plants belonging to Switzerland-based Holcim and Ireland-based CRH, respectively. Lastly, Bosnia & Herzegovina’s capacity is shared evenly between Germany-based Heidelberg Materials and Hungary-based Talentis International Construction, with one plant each.

Lafarge Srbija, Holcim's subsidiary in Serbia, announced plans for its second plant in the country, at Ratari in Belgrade, last week. No capacity has yet emerged, but the plant will cost €110m, making something in the region of the country’s existing 0.6 – 1.2Mt/yr plants seem likely. This would give Serbia over a third of total capacity in the Central Balkans and twice the number of plants of any other country there, expanding its per-capita capacity by 22 – 44%, from a regionally low 408kg/yr to 500 – 590kg/yr.

In announcing the upcoming Ratari cement plant, Lafarge Srbija laid emphasis on its sustainability. The plant will use 1Mt/yr of ash from the adjacent Nikola Tesla B thermal power plant as a raw material in its cement production. In this way, it will help to clear the Nikola Tesla B plant’s 1600 hectare ash dumps, from which only 180,000t of ash was harvested in 2023. Circularity has been front and centre of Holcim’s discussions of its growth in Serbia for some time. When Lafarge Srbija acquired aggregates producer Teko Mining Serbia in 2022, the group indicated that the business would play a part in its development of construction and demolition materials (CDM)-based cement and concrete.

Holcim’s Strategy 2025 growth plan entails bolt-on acquisitions in ‘mature markets,’ backed by strategic divestments elsewhere. Other companies have been more explicit about a realignment towards metropolitan markets, above all in North America, at a time when they are also diversifying away from cement and into other materials. Just why a leading producer should look to build cement capacity in Serbia warrants investigation.

Serbia is the only Central Balkan member of Cembureau, the European cement association. In a European market report for 2022, the association attributed to it the continent’s fastest declining cement consumption (jointly with Slovakia), down by 11% year-on-year. Like the rest of Europe, Serbia is also gradually shrinking, its population dwindling by 0.7% year-on-year to 6.62m in 2023, which limits hopes for a longer-term recovery. Serbia remains the largest country in the Central Balkans, with 39% of the total regional population.

Several factors have compounded Serbia’s difficulties as a cement-producing country. Firstly, like the Nikola Tesla B thermal power plant, its kilns run on coal. 50% of this coal originated in Russia and Ukraine in 2021, causing the entire operation to become ‘imperilled’ after the former’s brutal invasion of the latter in February 2022, according to the Serbian Cement Industry Association. In planning terms, this was a case of putting half one’s eggs in two baskets – and dropping them both.

Secondly, Serbia’s choice of export markets is mainly confined to either the EU or global markets via the River Danube, Black Sea and Mediterranean. Either way, it is in competition with a cement exporting giant: Türkiye. Serbia sold €19.7m-worth of cement in the EU in 2023, up by 63% over the three-year period since 2020 – 31% behind Türkiye’s €28.8m (more than double its 2020 figure).¹ One other Central Balkan country had a greater reliance on the EU market: Bosnia & Herzegovina. It exported €48.4m-worth of cement there, quadruple its 2020 figure and behind only China (€133m) and the UK (€54.7) in cement exports to the bloc by value.

Bosnia & Herzegovina’s cement industry underwent a different permutation at the start of 2024: an acquisition, replacing one EU-based player with another. Lukavac Cement, which operates the 800,000t/yr Lukavac cement plant in Tuzla, changed hands from Austria-based building materials producer Asamer Baustoffe to Hungary-based property developer Talentis International Construction. Talentis International Construction belongs to one of Hungary’s major family-owned conglomerates, Mészáros Csoport.

Besides Central Europe, Balkan countries have found a ready source of investments in the past decade in China. In construction alone, Chinese investments total €13.2bn in Serbia, €2.4bn in Bosnia & Herzegovina, €915m in Montenegro and €650m in North Macedonia.² This can be a booster shot to all-important domestic cement markets, but has some risks. Montenegro previously faced bankruptcy after Export-Import Bank of China began to call in an €847m loan for construction of the still upcoming A1 motorway in the country’s Northern Region. This did not put off the Montenegrin government from signing a new memorandum of understanding (MoU) with China-based Shandong Foreign Economic and Technical Cooperation and Shandong Luqiao Group for construction of a new €54m coast road in the Coastal Region in mid-2023.

In Montenegro, UK-based private equity firm Chayton Capital is currently funding a feasibility study for a partly state-owned cement plant and building materials complex at the Pljevlja energy hub in the Northern Region. Along with an upgrade to the existing Pljevlja coal-fired power plant, the project will cost €700m.

In 2026, EU member states will begin to partly tax third-country imports of cement and other products against their specific CO₂ emissions, progressing to the implementation of a 100% Carbon Border Adjustment Mechanism (CBAM) by 2034. Montenegro led the Central Balkans’ preparations for the EU’s CBAM roll-out with the introduction of its own emissions trading system in early 2021. Bosnia & Herzegovina will follow its example by 2026, but other countries in the region have struggled to conceive of the arrangement except as part of future EU accession agreements.

Based on the average specific CO₂ emissions of cement produced in the EU, the World Bank has forecast that exporters to the bloc will be disadvantaged if their own specific emissions exceed 5.52kg CO₂eq/€.³ By contrast, any figure below this ought to offer an increased competitive edge. Albanian cement has average emissions of 4.71kg CO₂eq/€, 15% below ‘biting point’ and 13% below Türkiye’s 5.39CO₂eq/€. Albania’s government consolidated its anticipated gains by quintupling the coal tax for 2024 to €0.15/kg. The figure is based on the International Monetary Fund’s recommended minimum CO₂ emissions tax of €55.80/t, 21% shy of the current EU Emissions Trading Scheme (ETS) credit price of €70.49/t.⁴

The Central Balkans is a region of apparently slow markets and industry growth regardless – to 11 cement plants, following the completion of current and upcoming projects. A recurrent theme of capital expenditure investments and the way investors talk about them may help to explain this: sustainability. Looking at the mix of technologies in the current nine plants, these include wet kilns and fuels lines built for conventional fossil fuels. This is not to presume that any given plant might not be happy with its existing equipment as is. Nonetheless, the overall picture is of a set of veteran plants with scope to benefit from the kind of investments which all four global cement producers active in the region are already carrying out elsewhere in Europe. Such plans may already be in motion. In late 2023, Titan Cement Group’s North Macedonian subsidiary Cementarnica Usje secured shareholder approval to take two new loans of up to €27m combined.

As the latest news from Serbia showed, taking care of existing plants does not preclude also building new ones. The cement industry of the Central Balkans is finding its position in the new reduced-CO₂ global cement trade – one in which old and new work together.

Changes are underway in South Asia’s second largest cement sector, with two legal developments that affect the industry set in motion in the past week. At a national level, the Competition Commission of Pakistan recommended that the government require cement producers to include production and expiry dates on the labels of bagged cement. Meanwhile, in Pakistan’s largest province, Punjab, a new law tightened procedures around the establishment and expansion of cement plants. At the same time, the country’s cement producers began to publish their financial results for the first nine months of the 2024 financial year (FY2024).

During the nine-month period up to 31 March 2024, the Pakistani cement industry sold 34.5Mt of cement, up by 3% year-on-year. Producers have responded to the growth with capacity expansions, including the launch of the new 1.3Mt/yr Line 3 of Attock Cement’s Hub cement plant in Balochistan on 17 April 2023. China-based contractor Hefei Cement Research & Design executed the project, including installation of a Loesche LM 56.3+3 CS vertical roller mill, giving the Hub plant a new, expanded capacity of 3Mt/yr.

Pressure has eased on the operating costs of Pakistani cement production, as inflation slowed and the country received a new government in March 2024, following political unrest in 2022 and 2023. Coal prices also settled back to 2019 levels, after prolonged agitation. Pakistan Today News reported the value of future coal supply contracts as US$93/t for June 2024, down by 2% over six months from US$95/t for January 2024.

Nonetheless, cost optimisation remained a ‘strong focus’ in the growth strategy of Fauji Cement, which switched to using local and Afghan coal at its plants during the past nine months. Its reliance on captive power rose to 60% of consumption, thanks to its commissioning of new waste heat recovery and solar power capacity. During the first nine months of FY2024, the company’s year-on-year sales growth of 14% narrowly offset cost growth of 13%, leaving it with net profit growth of 1%.

Looking more closely, the latest sales data from the All Pakistan Cement Manufacturers Association (APCMA) shows a stark divergence within cement producers’ markets. While exports recorded 68% year-on-year growth to 5.1Mt, domestic sales fell, by 4% to 29.4Mt. The association further breaks down Pakistani cement sales data into South Pakistan (Balochistan and Sindh) and North Pakistan (all other regions). Domestic sales dropped most sharply in South Pakistan, by 6% to 5.16Mt. In the North, they dropped by 3% to 24.2Mt. Part of the reason was a high base of comparison, following flooding-related reconstruction work nationally during the 2023 financial year. Meanwhile, the government finished rolling out track-and-trace on all cement despatches during the opening months of the current financial year, and commenced the implementation of axle load requirements for cement trucks. APCMA flagged both policies as potentially disruptive to its members’ domestic deliveries, amid a strong infrastructure project pipeline.

Pakistani producers suffer from overcapacity, but have established themselves as an important force in the global export market. They continue to locate new markets, including the UK in January 2024. Lucky Cement was among leading exporters overall, with a large share of its orders originating from Africa.

On 17 April 2024, the government of Punjab province set up a committee to assess new proposed cement projects, with the ultimate goal of conserving water. Falling water tables are considered a significant economic threat in agricultural Punjab. Besides completing an inspection by the new committee, proposed projects must also secure clearance from six different provincial government departments and the local government. While acknowledging the necessity of the cement industry, the government insisted that it will take legal action against any cement plant that exceeds water allowances.

Pakistan’s cement plants have grown in anticipation of a local market boom. Without this strong core of sales, underutilisation will remain troublesome, especially in North Pakistan where exposure is highest. At the same time, APCMA has given expression to the perceived lack of support affecting production and distribution. For an industry with expansionist aims, new restrictions on its growth and operations can feel like an existential menace.

Denmark: FLSmidth has signed a deal with Australia-based FCT ACTech to provide a new product for the online analysis of raw materials. Under the agreement, FLSmidth will incorporate FCT ACTech’s X-ray fluorescence (XRF) and X-Ray diffraction analysis (XRD) analysers in its new QCX Cube products. The partnership was formalised in August 2023.

Jens Asbjørn Pedersen, Global Product Manager for Sampling, Preparation and Analysis at FLSmidth, said “We are very pleased to be able to integrate FCT ACTech analyser units in our new QCX Cube analysis solutions for cement plants.” He continued, “We are starting with the launch of QCX Cube X10, which primarily targets raw meal applications, but it is our ambition to utilise FCT ACTech's innovative range of analyser units to also deliver advanced online XRD analysis solutions for clinker and cement.” He added that the company believes that such integrated solutions will provide ‘critical’ support for cement plants during the green transition, as alternative fuels and new secondary cementitious materials drive a need for further process and chemistry optimisation.

The QCX Cube X10 online elemental analyser is FLSmidth's newest analysis product for cement raw meal. Offering plug-and-play functionality, it includes sampling components, an energy dispersive X-ray fluorescence (EDXRF) analyser and a fully programmed local control system that are delivered pre-assembled in an air-conditioned container. Analysis results for calcium, silicon, aluminium and iron are provided as standard. Sodium and magnesium analysis can be provided with the addition of a helium purge, while other elements are available on request after a site-specific evaluation. The product is designed to be integrated with FLSmidth’s optimisation software QCX/BlendExpert.

FCT ACTech is the analytical instruments division of FCT International. It has developed and supplied a continuous on-stream analyser for more than two decades with products now covering raw mix, clinker quality and cement blend control.

The Hungarian government recently enacted Emergency Decree 320/2023, taxing all CO₂ emissions from the country’s 40 or so largest industrial enterprises. The government used emergency powers to set up a new taxation scheme, which undercuts existing free allowances under the EU emissions trading scheme (ETS). The scheme additionally penalises the trade in ETS credits. Cement producers announced that the new regulations will make it impossible for them to keep operating.¹

With regard to Hungary’s six active cement plants, the scheme comprises:

1 – A Euro20/t tax on CO₂ emissions, effective retroactively from 1 January 2023, payable by any large enterprise that uses EU Emissions Trading Scheme (ETS) free allowances to cover the majority of its CO₂ emissions. Plants that decrease their production, or that carry on non-CO₂-emitting activities at over 10% of their operations, will pay a higher rate of Euro40/t of CO₂.

2 – A 10% transaction fee for the sale of free allocations under the EU ETS, payable to the Hungarian Climate Protection Authority.

Less than three years ahead of full implementation of the EU carbon border adjustment mechanism (CBAM), the Hungarian government has seemingly moved unilaterally against cement production – this in a country surrounded by seven other cement-producing countries. Multiple foreign cement producers connected to the major market of Budapest by rail, river and road will be watching developments with interest. These include CRH, which, besides two smaller plants inside Hungary, operates the 800,000t/yr Cementáreň Turňa nad Bodvou plant, immediately over the border in Slovakia.

This comes at a time when the domestic cement industry is facing historically high costs and low demand, with a 30% year-on-year decline in construction activity in July 2023, following double-digit inflation throughout 2022 and the first half of 2023.

Catastrophising may be a common symptom of environmental regulation in industry associations, but one can understand on this occasion. The Hungarian cement and lime industry association, CeMBeton, backed its members’ gloomy announcement about their future with an estimate for extra annual taxes of ‘several billion forints’ (1bn forint = US$2.84m), in a statement following the decree. Assuming annual CO₂ emissions of 565kg/t across its 5.4Mt/yr cement capacity, the sector might expect to pay US$61m/yr in CO₂ rates alone.^{2, 3} According to analyst ClearBlue, the government will raise additional tax revenues worth US$278m/yr across all of the 40 aforementioned heavy emitters in Hungary.⁴

It may seem surprising that CeMBeton did not even draw up a projected tax bill during consultations over the new tax scheme – but, in fact, no such consultations took place. In its most recent statement, the association said “We do not know the government’s intentions.” Outside of official releases, Hungary’s cement producers have not always been so reserved about the government’s perceived aim.

Global Cement reported in April 2023 that the Hungarian government was allegedly interfering in the cement sector to make producers sell up – as per accusations by an anonymous industry executive.⁵ There is arguably a course of action on the government’s part which, more or less, appears consistent with this aim:

October 2020 – The Hungarian Competition Authority (GVH) starts competition supervision proceedings against CRH, Duna-Dráva Cement and Lafarge Cement Magyarország.

July 2021 – Emergency Decree 2021/404 imposes a 90% tax on producers’ ‘excess’ profits, based on threshold cement sales revenues of Euro56/t. Additionally, producers must report their exports.

September 2021 – GVH finds insufficient evidence to support the initiation of competition supervisory proceedings in the cement industry.

January 2023 – (Retroactive) entry into force of CO₂ emissions tax.

May 2023 – The government of Hungary reportedly initiates negotiations to acquire Duna Dráva Cement and Holcim Magyarország, according to the Hungarian builders’ association, National Professional Association of Construction Contractors (ÉVOSZ). Duna Dráva Cement owners Heidelberg Materials and Schwenk Zement state that they have entered into no such negotiations, while Holcim declines to comment.

July 2023 – The Act on Hungarian Architecture lets the government dictate producers' volumes and prices and require them to supply cement to National Building Materials Stores (a proposed state-owned construction materials retail monopoly).⁶ Additionally, the government gains a right of first refusal over the divestment of any asset by the cement industry’s foreign owners.

20 July 2023 – The government enacts Emergency Decree 320/2023. ETS transaction fees enter into force.

The government can now expect a legal challenge to its latest move. CeMBeton’s first ally may be the font of all emissions legislation – the EU itself. Within the EU ETS framework, tax rates are down to member states to determine. However, the introduction of a transaction fee may constitute an illegal restriction to free allowances, OPIS News has reported. The association has also indicated its readiness to mount a constitutional challenge, specifically with regard to the legislative retrofit involved in the CO₂ emissions tax. The Fundamental Law of Hungary does not generally permit legislation to apply retroactively, though how courts will balance this consideration against the rights of the government is untested.

The government amended the constitution to provide for new emergency powers, and subsequently adopted them in May 2022, in response to the ‘state of danger’ created by Russia’s war in Ukraine – though its actions on the international stage suggest careful neutrality, if not ambivalence. At home, the war has brought a consolidation of the government’s control over various areas of life, including the economy, according to Human Rights Watch.⁷

Climate protestors around the world might be glad to see governments wield emergency powers against their own heavy industries. In Hungary, however, the wider sustainability goals are not yet clear with regard to a policy that seems, at least partly, politically motivated.

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.

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.

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.
