India: The environmental public hearing for Meghatop Cement's proposed integrated cement plant in Wahiajer village, Elaka Narpuh, was conducted on 18 October 2024, according to The Shillong Times. The plant is planned to have a 3.3Mt/yr clinker capacity and 16MW waste heat recovery system, and has faced a mixed reaction from several community members. Franky Laloo from the Meghalaya Pollution Control Board led the hearing, attended by district officials, villagers and company representatives. Supporters emphasised the potential community benefits of the plant, but the Jaintia Women Council expressed some concerns, saying that “We intended to voice our opposition at the hearing, but were prevented by village volunteers and police. A hearing that only accommodates supporters is unacceptable.”

India: UltraTech Cement has commissioned an additional 1.2Mt/yr of grinding capacity at its Arakkonam unit in Tamil Nadu. This expansion is part of a broader 22.6Mt/yr capacity increase announced back in June 2022. With this latest addition, UltraTech Cement's total cement capacity now stands at 156Mt/yr.

India: Fornnax has introduced the SR-MAX2500 shredder, designed for municipal solid waste (MSW). The machine features hydraulic motors and a unique cutter design, aiming to serve large-scale recyclers and cement plants.

Jignesh Kundaria, CEO and director of Fornnax, said "With the SR-MAX2500, we're poised to transform the waste management landscape in India and beyond. Our goal is to line up MSW recycling industries with a robust, efficient and sustainable solution.”

The SR-MAX2500 is engineered for India, accommodating the specific challenges of highly contaminated local waste. The company says that the shredder will enhance efficiency, reduce operational costs and minimise downtime.

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.

India: Cement demand in India is projected to increase by 7 - 8% to approximately 475Mt in the 2025 financial year, down from a compound annual growth rate of about 11% between financial year (FY) 2022 and FY 2024, according to a report by CRISIL Ratings. The company analysed 18 cement producers, which account for over 85% of domestic sales volume. The forecast follows a 3% growth in demand during the first half of FY 2024, affected by an extended heatwave and a labour shortage during the general elections, the Financial Express has reported.

Director of research at CRISIL Market Intelligence and Analytics, Sehul Bhatt, said "Cement demand is expected to rebound in the second half of the 2024 financial year, as construction activity gathers pace across infrastructure and housing segments post-monsoon. Healthy monsoon, improved labour availability after the festive season, and an increase in government spending on infrastructure and housing should drive demand up 9 – 11% in the second half of the year, taking the annual growth tally to 7 – 8%."

Adani Group’s latest target for acquisition in the cement sector was revealed this week to be Heidelberg Materials’ India-based business. The Economic Times newspaper reported that talks have started between the companies with a tentative value of US$1.2bn. As might be expected, Adani Group is said to be keen to close the deal down quickly. It wants to avoid an auction situation where it might face competitors. However, there may be some disagreement about the actual production capacity of Heidelberg Materials’ companies in India. If a deal were finalised, it might be completed by early 2027.

Heidelberg Materials’ capacity in India was listed as 14Mt/yr by the press but this could include the company’s grinding plants as well as its integrated ones. Heidelberg Materials, itself, says it has a capacity of 12.1Mt/yr from three integrated cement plants, four grinding plants and a terminal across 12 states. Data from the Global Cement Directory 2024 suggests that this refers to the group’s integrated cement capacity. The plants are roughly split equally between subsidiaries Heidelberg Materials India and Zuari Cement. Heidelberg Materials entered the Indian market in 2006 when it acquired Mysore Cement, Cochin Cement and established a joint-venture with Indorama Cement. It later added Zuari Cement to its portfolio when it bought Italcementi in 2016. The group used to run four integrated plants in India until in May 2024, when it shut down clinker production at its Ammasandra plant in Karnataka, although grinding activity has continued at the site.

Back in 2021 Heidelberg Materials’ CEO Dominik von Achten said that the group had considered selling anything following a business review. "There are no sacred cows. Everything was on the table." Indonesia was generally perceived by analysts as a likely sale target in the developing markets but nothing happened in the end. India wasn’t mentioned at this time, although no doubt it was being considered. Yet Holcim divested its businesses there in 2022. These were picked up by Adani Group for US$6.4bn. This, in turn, kicked off the rivalry in the Indian cement sector between market leader UltraTech Cement and Adani Group. Both companies are now in a race to build production capacity through expansion, new plants and acquisitions.

One reason why Heidelberg Materials may have decided now in particular to talk to Adani Group can be seen in its recent financial reports. In 2023 it said that its “cement and clinker deliveries increased moderately, as massive excess capacities persist in our core markets.” It then followed this up in 2024 by noting that deliveries were slightly down year-on-year in the first half of the year. It blamed this on excess capacity in South India. The subsidiary reported a net loss of €6.3m in 2023. An article by Holtec Consulting in the October 2023 issue of Global Cement Magazine implied that capacity utilisation was 56% in 2023, the lowest of the country’s regions. This is a particular problem for the company given that Zuari Cement is based in the south.

Funnily enough, a sale of 12.1Mt/yr capacity for US$1.2bn suggests a price of US$99/t, a similar figure to what Adani Group paid to buy Holcim’s assets in India in 2022. This may explain why Adani Group is trying to avoid an open sale for the Heidelberg Materials assets. Then again, maybe the market in southern India really is suffering. By comparison, when Adani Group concluded a deal to buy Penna Cements in August 2024 it paid US$1.2bn for an integrated capacity of about 7Mt/yr or around US$170/t. Factor in the low capacity utilisation rate in south India and this potential Adani-Heidelberg Materials deal ends up at roughly the same price.

Something that may help Adani Group reach its goal might be a formal merger between its two main cement companies, Ambuja Cements and ACC. The Mint newspaper reported on it this week, saying that Jefferies and Axis Capital has been hired as an advisor. This certainly makes sense in synergy savings but moving all the mining and leasing rights around might prove cumbersome. Regardless, Adani Group is on an expansion drive, with a capacity of 140Mt/yr targeted by 2028. All the smaller cement companies in the country are potentially targets.

India: Shree Cement has signed a memorandum of understanding with the Department for Promotion of Industry and Internal Trade (DPIIT) to support startups in India's manufacturing sector. This partnership aligns with the government's ‘Make in India’ vision to encourage domestic manufacturing and build a self-reliant economy. Through this collaboration, startups will gain access to Shree Cement’s industrial expertise, network and resources, which will help them scale their operations and develop solutions. This initiative is expected to create new job opportunities, boost local production and reduce import dependency.

India: Adani Group is considering a merger of Ambuja Cements and ACC into a single entity, Adani Cement, by 2028. Mint News has reported that the group, which began integrating the operations of the two companies recently, may also include Sanghi Industries in the merger. The proposed merger would involve a share swap between the companies, with all existing brand identities retained.

India: Adani Group is negotiating the purchase of Heidelberg Materials' cement business in India, potentially valued at US$1.2bn, according to Reuters. Heidelberg Materials has been present in India since 2006, and owns four plants with a total capacity of 12.6Mt/yr. The acquisition discussions come amidst increased consolidation in the Indian cement sector, driven by heightened demand due to government investment in housing and infrastructure.

India: Orient Cement has won an order from Madhya Pradesh Power Generating Co to install a clinker grinding unit at Satpura Thermal Power Station, Sarni. The ‘work order’ was issued by the company to install the grinding unit, along with a 25-year fly ash supply contract. Earlier in August 2024, Orient Cement said that it anticipates a robust demand recovery in the second half of the financial year post-monsoon.
