New developments in alternative cement
16 October 2024One 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!
Poland: The Polish cement industry is under threat from increasing Ukrainian cement imports, which have risen by 106% year-on-year in the first half of 2024, according to Warsaw Business Journal. These imports, making up 91% of all cement imports into Poland, could exceed 500,000t by the end of 2024. Despite a projected 3.6% rise in domestic production to 17.2Mt, the competition from lower-cost Ukrainian cement, not subject to EU climate regulations, threatens Poland's economy and job market.
Update on the Central Balkans, August 2024
28 August 2024The 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.

Italy: The President of the Italian cement association Federbeton, Stefano Gallini, has highlighted the disadvantages of cement and clinker production relocating to non-EU countries with lower costs, according to Milan Finance.
New data from from the Federation of Italian Cement Producers reports that imports of non-European cement into Italy rose by 22.6% year-on-year in 2023 to 3.6Mt. From 2018 to 2023, the import of intercontinental cement has increased by 572%, compared to a 6.5% increase in European purchases.
Ukraine: The Ukrainian cement industry, represented by the Ukrcement Association, is urging the government to revise the recent changes in electricity import regulations under martial law. Following the increase from a 30% EU electricity import requirement to 80%, mandated by Resolution No. 661 on 1 June 2024, the industry faces heightened costs and technical challenges due to limited border crossing capacities.
The association said "Given that cement production is energy-intensive and it is the main component for military and civilian construction, we ask the Ukrainian government to return to the previous 30/70 proportion. This proportion will ensure reliable energy supply to industrial enterprises of Ukraine, which will help maintain the current pace of economic recovery in Ukraine in the face of military aggression by the Russian Federation."
The industry's proposals to mitigate the situation include reducing the minimum import share to 50%, enhancing interstate crossing capacities and revising the distribution of mandatory imported electricity purchases.
Germany: Calix's subsidiary Leilac and Heidelberg Materials have formed a joint venture to build the Leilac-2 low emission cement demonstration plant at Heidelberg's Ennigerloh facility. Construction is set to begin in 2025, with the plant's commissioning scheduled for mid-2026. The Leilac-2 plant will showcase a module capable of capturing up to 100,000t/yr of CO₂ emissions from cement and lime production. Following construction and commissioning, Leilac-2 will be operated for up to three years to test the performance of the technology.
The project benefits from €16m in funding from the EU's Horizons 2020 programme and contributions from partner cement companies. Following construction, Heidelberg Materials may repay Leilac's capital contribution, and the partners will consider a full-scale commercial installation of Leilac technology at a Heidelberg plant. Plans for Leilac-3 envisage a significantly increased capture capacity, potentially capturing 0.5–1Mt/yr of CO₂.
Leilac CEO Daniel Rennie said "The formation of a joint venture with Heidelberg Materials for the Leilac-2 plant marks another important milestone for commercialisation of the Leilac technology. We look forward to continuing to collaborate with Heidelberg Materials to demonstrate and deploy cost-effective solutions to decarbonise cement production at commercial scale.”
UK cement industry endorses CBAM proposal
14 June 2024UK: The UK cement industry has welcomed the government's proposal for a UK carbon border adjustment mechanism (CBAM) but urged for its implementation by 2026 to align with the EU CBAM and avoid competitive disadvantages. The Mineral Products Association (MPA) and UK Concrete responded to the government’s consultation, highlighting the need to level the carbon-cost playing field between domestic production and imports, as well as to prevent high-emission cement imports from impacting the UK market. It emphasised the urgency of introducing CBAM in 2026 rather than the proposed 2027, to prevent import diversion from the EU.
The MPA is calling for accurate measurement and reporting of embodied emissions by importers, clear calculation of CBAM rates, improved transparency in UK trade data and strict enforcement procedures with high penalties for non-compliance.
MPA executive director for energy and climate change Diana Casey said "The UK has a great opportunity to accelerate the transition to net zero while securing domestic cement supply for priority construction like housing and infrastructure. A well-designed CBAM is vital to maintain the level playing field and ensuring competitiveness of domestic cement production while it continues its transition to net zero.’
Europe: Cembureau has released an update to its net zero roadmap. The roadmap now aims for a 37% reduction in CO₂ emissions related to cement production by 2030, 78% by 2040 and net zero cement production by 2050, with potential to become carbon negative.
The roadmap also states the key policy measures needed to meet these updated goals, including: The implementation of a watertight carbon border adjustment mechanism (CBAM), the increase in funding for decarbonisation initiatives, the need for guaranteed access to affordable decarbonised energy, infrastructure and raw materials, as well as the creation of lead markets for low carbon, circular products.
President of Cembureau, Ken McKnight said "In the past four years, the European cement sector has clearly moved from ambition to deployment. We have the potential to scale up our climate ambition, but we need policymakers to match this ambition through decisive policies."
Polish cement industry advances with CCS technology
19 April 2024Poland: Polish cement producers are set to build carbon capture installations, supported by government policies. After a decline in production from nearly 19Mt in 2022 to about 16.5Mt in 2023, the industry is facing an increase in cheaper imports from outside the EU, particularly Ukraine, and CO₂ emission fees that account for 30% of the cost of 1t of cement, according to the Dziennik Gazeta Prawna newspaper. The EU has also introduced a carbon border adjustment mechanism (CBAM) for imports.
Despite these challenges, the Kujawy cement plant in Bielawy, owned by Holcim, is launching the large-scale implementation of carbon capture and storage (CCS) technology.
Holcim Polska's president, Maciej Sypek, said "The construction of carbon capture installations in our plants will cost between €320m and €400m. We received a €264m grant from the European Commission's Innovation Fund." According to Sypek, the project is currently in the design phase, with construction expected to start in 2025 and operations beginning in early 2028.
The implementation of CCS at the Kujawy plant could potentially lead to an industry-wide adoption of the technology, costing between US$3.7bn and US$4.9bn, according to the newspaper. Holcim Polska plans to liquefy the CO₂ and transport it by rail to a terminal in Gdańsk, where it will be shipped to the North Sea for underground storage. Cement producers are urging the Polish government to appoint a commissioner for CCS infrastructure and to enact legislative changes to support the construction of such installations. They also believe that rapid modernisation of the energy sector needs to occur to support the energy-intensive process of gas capture.
Germany: Heidelberg Materials has begun work on the GeZero project at its Milke plant in Geseke. The €500 million project will implement carbon capture and storage (CCS) technology to prevent the release of CO₂, instead capturing and storing it under the North Sea. According to the Westfälische Rundschau, the project has secured €191m in funding from the EU, with Heidelberg Materials covering the remaining amount. The company anticipates completing the plant conversion by 2029, with interim CO₂ transport via rail and potential future pipeline connections. According to the company, around 700,000t/yr of CO₂ is currently produced by the plant.
There had been potential changes in project partnerships due to the sale of BASF subsidiary Wintershall Dea, which was to provide the transport and storage solutions, to Harbour Energy. However, plant manager Steffen Gajewski expects that planning for the conversion of the plant will be completed in 2025, when the new oxyfuel kilns to capture the CO₂ will be ordered and installed.
