Europe: Titan Group and Ecocem will partner for the development of Ecocem's low-carbon cement technology, ACT, in Europe. This partnership will produce a new low-carbon cement by substituting a ‘substantial portion’ of clinker with supplementary cementitious materials, reportedly reducing cement's carbon footprint by up to 70%.

Iraq: Eggersmann Anlagenbau has expanded its refuse-derived fuel (RDF) production facility in Sulaymaniyah, operated by Ecocem Environmental Solution, part of the Faruk Investment Group. The expansion includes a new Eggersmann TEUTON ZS 55 single shaft shredder and four additional lanes for biological drying using the CONVAERO system. This system is integral to the Eggersmann RDF process, which converts municipal solid ‘waste’ into high calorific value RDF used by the regional cement producers Gasin Cement Company and Bazian Cement Company. The facility, which has a capacity of 1100t/day of RDF, will see an increase with the expansion. The Eggersmann FUEL process utilises biowaste in RDF production, improving both the quantity and quality of the fuel through biological drying in the CONVAERO system, relying on the natural warmth of the composting process. This method reduces methane emissions at landfill sites by integrating biomass into the fuel, according to the company.

Business development manager at Eggersmann, Eugen Becker, said "A particularly high quality substitute fuel is being produced with the Eggersmann FUEL process in Sulaymaniyah, whose net calorific value can be precisely tailored to the customer’s needs over the adjusting of the drying period. This quality makes a noticeable economic difference."

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.

US: Ireland-based Ecocem has appointed Mike Donovan as Technical Director for its US business operations. He will be responsible for overseeing key aspects of Ecocem’s business in the US, with a focus on widespread commercial adoption of the company’s low-carbon cement technologies, including ACT, by the US market.

Donovan most recently developed and brought a new natural pozzolan to market with Geofortis. He started his career in concrete in the 1980s working at companies including as Sherman Industries, Blue Circle Cement Tarmac and Central Concrete Supply (US Concrete). He is a graduate in civil engineering from the University of Texas at Austin.

France: Irish cement producer Ecocem plans to industrialise a new technology that will be implemented at its Dunkirk site in northern France by 2025. The technology, called ACT, replaces clinker with limestone filler to reportedly reduce the carbon footprint of cement by 70% compared to the average French cement.

The company is relying on public funding from Bpifrance, the Hauts-de-France region and the urban community of Dunkirk.

Ireland: Ecocem has appointed Ghizlane Ruf as its Chief of Staff. The role will see her work with the company’s senior executives to prioritise strategic business decisions and enhance team efficiency. She has been in post since the start of 2024.

Ruf previously worked for LafargeHolcim from 2016 to 2022 in a variety of customer service roles eventually becoming the Head of Customer Services for Cements and Aggregates and Standards France. She has also worked for Salesforce and Teksial.

Ireland: Ecocem has appointed Sally Anne Sherry as the Managing Director for its UK and Ireland business operations. She succeeds Susan McGarry in the post, who has become the group’s Director of Public Affairs and Sustainability.

Sherry holds around two decades of experience in the property sector and has worked as a non-executive director for several companies. Notably she worked as a Director and General Counsel for property development and investment company Bartra from 2015 to 2023. She holds legal qualifications from the University of Galway.

Netherlands: Ireland-based Ecocem has agreed a deal with Overslagbedrijf Moerdijk (OBM) to expand production and storage capacity at the company’s Moerdijk slag cement grinding plant. The project is intended to allow the unit to both produce and store the company’s advanced cement technology (ACT) product. It will quadruple the storage capacity for key materials at the site up to 40,000t. Ecocem has signed a long-term agreement to lease the site from OBM, who will manage the handling and storing materials on Ecocem’s behalf.

This expansion of the Moerdijk plant is part of Ecocem’s plans to expand its manufacturing and storage capacity to support the commercialisation of ACT across all its plants. It follows the expansion of its Dunkirk plant in France, which was announced in June 2023. These expansion plans will be supported by licencing and partnership strategies to accelerate availability and adoption of scalable low clinker cement at speed.

Conor O’Riain, Managing Director (Europe), at Ecocem, said: “We are increasing our capacity at all of our locations and our deal with OBM is a hugely important aspect of our expansion strategy. It will accelerate our ability to manufacture ACT our low clinker cement technology and make it available commercially by 2026. At the same time, we are actively pursuing licensing and partnership agreements in the construction industry to ensure the benefits of this technology are shared widely and we accelerate progress to Net Zero.”

In February 2024 Ecocem said that its ACT technology received an ETA (European Technical Assessment), which provides the technology with a route to full commercialisation by 2026.

France: Ecocem has launched a new low-carbon advanced cement technology (ACT) cement, aiming for widespread adoption in European construction projects. The ACT range promises a clinker concentration of 20%, lower than the current norm of 35% minimum.

Jean-Christophe Trassard, Director, Marketing of Sustainable Innovation, said "We achieve competitive rates by controlling granularity, the fineness of grinding and admixtures. We have also greatly developed our thinking on the addition of additives in our formulations, which required more than fifteen years of R&D and the filing of six patents."

This product contains locally sourced additives, with the capability to adapt mixes to regional availability. The ACT cement is expected to reduce water usage by one-third compared to conventional concrete. An ACT-based concrete reportedly emits 198kg CO₂/t, a substantial reduction from the 614kg CO₂/t for standard concrete in France.

Gaining market entry for ACT required European technical evaluation and European assessment document certification, currently pending in the EU Official Journal. Trassard added, "As we are dealing with clinker rates below the standards, we had to go through this certification, which gives us a very good passport for the European markets. However, local administrative variations will have to be carried out subsequently."

In France, Ecocem has already applied for ATEX certification to facilitate deployment of the ACT range, expected later in 2024. Ecocem aims to include the ACT range in standard norms by 2026.

Ireland/France: Ecocem will showcase its Advanced Cement Technology (ACT) at the Buildings and Climate Global Forum in Paris on 7-8 March 2024. The French Government and United Nations Environment Programme (UNEP) will host the event, supported by the Global Alliance for Buildings and Construction (Global ABC). It aims to advance the climate outcomes of the United Nations Climate Change Conference (COP28) in 2023. Ecocem joins global policy-makers, industry stakeholders and international organisations as the event’s sole international cement technology company exhibitor.

Managing director Donal O'Riain said "The Buildings and Climate Global Forum is happening at a crucial moment for the planet. Urgent and deep decarbonisation of construction materials is essential to achieving the 2015 Paris Agreement targets.” He continued “Ecocem’s ACT low carbon technology can decarbonise the cement sector on a trajectory consistent with 1.5°C of global warming, the first major industry sector to achieve this feat. But we must now mobilise resolutely, rapidly and globally to deploy this technology. The first ambition should be a 50% reduction in CO₂ emissions from cement by 2030. Technology is no longer the barrier."
