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.

Ireland: Mannok, Sweden-based minerals company Boliden and the South Eastern Applied Materials (SEAM) research centre at South East Technological University in Carlow, Wexford and Wicklow in Ireland have launched a 30-month project to reduce the embodied CO₂ emissions of cement. The project will investigate possible uses of shale as a supplementary cementitious material (SCM) in cement production and the CO₂ curing of cement paste-based mine backfill. Enterprise Ireland has supplied funding worth €700,000 for the collaboration.

Mannok operations director Kevin Lunney said "We are delighted to be working with SEAM and Boliden on this critical research for the cement sector, which could have many far-reaching benefits for the construction sector more generally. Finding local, viable, low-carbon solutions for the industry can make a major contribution to lowering emissions in Ireland."

Boliden specialist development engineer Adam McElroy and section-mill process head Colum Burns said "This project will greatly enhance our knowledge and understanding of the potential for developing low carbon cement for mine backfill purposes and for utilising backfill systems as a carbon sink. The project will also investigate synergies between the cement manufacturing and mining industries that could enhance the sustainability of both industries."

One surprise at the end of August 2024 was that Türkiye-based Çimsa has agreed to buy a majority stake in Ireland-based Mannok. The subsidiary of Sabancı Holding signed a deal to acquire just under a 95% stake in Mannok Holdings based on an enterprise value of Euro330m for 100% of the shares. The final purchase price will be determined later in the process, as will a potential completion date subject to the usual regulatory approvals.

Çimsa has described the deal as its “third major global initiative in the past three years” following expansions in the US and Spain. Çimsa started production at its 0.3Mt/yr white cement grinding plant in Houston, Texas in 2019. It is currently planning to set-up a 0.6Mt/yr grey cement grinding plant, also in Houston, with operation expected to start by the end of 2024. Its Spain-based business received a boost in mid-2021 when it purchased the Buñol white cement plant in Valencia from Cemex. Outside of Türkiye the company also operates a few terminals in Germany and Italy. Of interest to this article it established a subsidiary for sales in the UK in mid-2023.

Mannok was previously known as Quinn Group before it was rebranded in 2020. In addition to cement the company sells a range of construction products including PIR (polyisocyanurate) insulation, aircrete thermal blocks, roof tiles and precast concrete. The company is headquartered at Derrylin in Fermanagh, Northern Ireland in the UK but it operates in both Ireland and the UK. It runs a 1.4Mt/yr integrated plant at Ballyconnell, County Cavan in Ireland, just across the border from Derrylin. With the 17th Global CemFuels Conference scheduled to take place next week in Dublin, it is worth noting that this cement plant had a recent upgrade of interest to the alternative fuels sector. In 2023 the company said that it had installed the world’s first FLSmidth Fuelflex Pyrolyzer at a cement plant following an earlier pilot of the system back in 2018. It is used to replace coal with solid recovered fuels (SRF) in the pre-calcination stage of cement production. Later in 2023 Mannok said that the equipment was reducing its CO₂ emissions by 58,000t/yr.

As reported in the October 2023 issue of Global Cement Magazine, cement from the Ballyconnell plant is sold in both Ireland and the UK. In 2022, 35% of its sales were in Ireland, 30% in Northern Ireland and the remaining 35% in the rest of the UK. The company uses a storage unit at Warrenport in Northern Ireland to despatch cement to a 8400t cement storage and distribution at Rochester in Southern England.

Çimsa said that the acquisition is intended to help it to increase the share of its revenue in foreign currencies to over 70%. It is not a revelation that Çimsa might want to do this given the parlous state of the economy in Türkiye since 2018. Interest rates are high and the Turkish Lira has lost value. Çimsa raised the issues this has caused in its 2023 annual report. These include higher costs for imported goods and services such as energy, equipment and engineering services. In 2023 the company reported that 57% of its sales consisted of foreign currency-based revenue. The same year exports represented just under 40% of the company’s total revenue. Overall, Çimsa’s revenue fell slightly year-on-year in 2023, in part due to the divestment of a cement plant and other assets, but earnings rose significantly.

Buying Mannok gives Çimsa another route into the European Union (EU), via Ireland, and the UK. Crucially, this gives its first integrated grey cement production site outside of Türkiye. Both of these things are especially useful for an export-focused company facing increasing hurdles to sales in the guise of the EU Emissions Trading Scheme. It also helps the business to further hedge against negative currency exchange effects back home in Türkiye. So ‘Sláinte’ to Çimsa and Mannok, and good luck.

Ireland: Sabancı Holding subsidiary Çimsa Çimento has signed a share purchase agreement to acquire a 95% stake in Mannok. Reuters has reported the total enterprise value of Mannok as €330m. In determining the eventual purchase price, Çimsa Çimento says that it will make adjustments for any debt or related items. The deal marks the group’s entry into Ireland and the UK, where Mannok also distributes cement.

Mannok chair Adrian Barden said "Çimsa and the broader Sabancı group are a superb fit for Mannok as new long-term strategic owners, with excellent sustainability credentials and know-how. The group is steeped in cement manufacture and building products and, as a diverse conglomerate, it also has interests in retail and food, important sectors for our packaging business. We are very pleased that Sabancı has endorsed the Mannok brand and has agreed to back local management's plans to accelerate our sustainability and growth ambitions.”

Çimsa Çimento CEO Umut Zenar said "We believe this agreement marks the beginning of a new era for Mannok. At Çimsa, our model is to back great local businesses and management, and we look forward to creating new employment opportunities in the region as we support Mannok's continuing growth and sustainability ambitions. Given its border location, Mannok has unique access to UK and EU markets, and we see it as a key stepping stone in expanding our footprint in Western Europe. For Mannok staff, joining the Sabancı ecosystem will also present a world of opportunity for career development and progression and exposure to innovation in product development, sustainability and digitisation."

US: Continental Cement has ordered a Fuelflex Pyrolyzer alternative fuels combustion system from Denmark-based FLSmidth for installation at its Davenport plant in Buffalo, Iowa. The supplier says that its product offers a lower capital expenditure compared to competing systems, can control NO_x emissions without the need for ammonia water and can be installed without a long shutdown period. This is the first commercial installation of the Fuelflex Pyrolyzer system following a pre-commercial installation at the Mannok cement plant in Northern Ireland, UK, in 2022.

David Loomes, the president of Continental Cement, said “We’re very excited about what the Fuelflex Pyrolyzer will do for our process.” He added, “We’re planning to achieve 55% fossil fuel replacement across the plant, utilising non-hazardous waste that would otherwise go to landfill or incinerators. The economic and environmental benefits of this technology are very significant and a key element of executing our carbon reduction commitment.” Continental Cement, a subsidiary of Summit Materials, has been incorporating waste materials as fuels for more than 30 years.

Jens Jonas Skov Larsen, Head of Capital Sales at FLSmidth, said “Mannok has called the Fuelflex Pyrolyzer a game-changer for the cement industry.” He continued, “This system effectively rearranges the order of the combustion process to make use of hot preheater meal, which is the heat source for the waste fuel pyrolysis. It’s a more efficient way of burning alternative fuels and it comes with a host of benefits, including reduced emissions and a more stable process.”

The installation at Davenport cement plant is expected to start operation in 2024. The full commercial launch for the system is scheduled by 2025. No value for the order has been disclosed.

Ireland/UK: A six-month feasibility study conducted by Mannok at its Derrylin plant, in conjunction with Catagen, has found a number of ways that the cement producer can reduce its CO₂ emissions. Using Catagen’s HGEN renewable hydrogen generator with waste heat recovery could potentially decrease the cement plant’s annual CO₂ emissions by 7%. In addition the study found that using biohydrogen generation from waste biomass could generate larger volumes of hydrogen with less renewable energy required, compared to electrolytic hydrogen generation. Using Catagen’s BIOHGEN process in this way could minimise carbon intensity by a further 18%. A combined group of engineers from Mannok and Catagen worked on the project.

Kevin Lunney, operations director at Mannok, said “We are very excited to be working with the Catagen team, who have demonstrated a deep level of technical ability and competency during the feasibility work. I have no doubt that Mannok will derive significant value from the work already completed, with many new opportunities for collaboration now presenting that we would not have considered before. Achieving Net Zero is now the primary goal for our business and I expect Catagen will play a significant role in our achieving that goal, which we expect will have major benefits for the sector overall.”

In early April 2023 Mannok revealed that it had secured funding from the UK Government Green Energy Scheme to support its energy transformation programme. The first phase of the initiative, which the funding will support, is the generation of onsite green hydrogen to replace the use of diesel in over 70% of the company’s 150 heavy-goods truck fleet.

Belfast-based Catagen started as a testing company providing emissions data to the automotive sector. It has started working in other industrial sectors - such as cement, glass and steel in Europe and the US – as part of its ClimaHtech product range.

UK: The World Cement Association (WCA) has appointed three new directors: Fabien Charbonnel, the chief executive officer (CEO) of Cem’In’Eu; Xu Gang, the chair of the board of Maweni Limestone and Vice President and Head of Overseas Area of its parent company Huaxin Cement; and Kevin Lunney, the chief operations officer of Mannok Holdings. The appointments were agreed at the WCA General Assembly Meeting, which took place in January 2023.

At the same time Mohammed Ali Al-Garni, the CEO of Saudi Cement, and Roland van Wijnen, the CEO of PPC, were re-elected to the board of directors. Vincent Lefebvre, the founder and executive chair of Cem’In’Eu, and Mahendra Singhi, the managing director and CEO of Dalmia Cement, have also resigned as directors. They joined the board of directors of the WCA in 2019 and 2020 respectively.

Ireland/UK: An Irish high court has granted Mannok an injunction to prevent former Quinn Industrial Holdings CEO Seán Quinn from trespassing on the site of its Derrylin cement plant and quarry in Cavan and County Fermanagh, Northern Ireland, UK. The Irish Examiner newspaper has reported that the company cited safety concerns over Quinn's presence near industrial equipment and a sheer quarry drop. His media statement in 2021 that he would 'do anything' to remove its directors compounded Mannok's 'sense of unease.'

UK: Mannok recorded sales of Euro270m in 2021, up by 16% year-on-year from Euro233m in 2020. The company’s earnings before interest, taxation, depreciation and amortisation (EBITDA) fell by 17% to Euro25.8m from Euro31.1m. The group attributed this to substantial cost absorption beginning in mid-2021. Energy prices rose by 66% year-on-year, while the cost of carbon emissions trading scheme (ETS) credits more than doubled to Euro80/t at the end of the year.

Mannok said that demand for its products remains resilient, supported by stronger cost recovery. It added that a levelling out in energy prices has driven stronger profitability in the first quarter and April of 2022.

UK: Paul Brogan has started his two-year tenure as the chair of Mineral Products Association Northern Ireland (MPANI). He is the managing director of McQuillan Companies and has worked for the company for over 25 years. Paddy Mohan, the cement sales director of Mannok, will work as vice chair. MPANI is an industry body which represents the mineral products industry in Northern Ireland.
