Chile: Melón has inaugurated a new 0.25Mt/yr grinding plant in Punta Arenas. The project had an investment of US$45m, according to the El Pingüino newspaper. In its first year of operation an output of 80,000t is planned. It is the first cement plant in the Magallanes Region. Spain-based Cemengal supplied a Plug&Grind Xtreme grinding unit for the project.

Jorge Eugenín, the chief executive officer of Cementos Melón, attended the event and said, “For us Magallanes has always been an interesting market. Its consumption is comparable to cities in developed countries.” He added that the region has a per capita cement consumption level of 550kg/yr compared to the Chilean mean of 280kg/yr.

The cement producer previously announced plans to double the production of the plant by building a second grinding mill if the market supported it. Eugenín commented that the announcement of a large-scale hydrogen project in the region by Total Eren in late 2021 could add further momentum to expansion plans for the new cement plant.

Canada: The Government of Quebec says it will allocate up to US$36m towards a US$110m upgrade project at Ciment Québec’s integrated St Basile plant. The plant intends to build a new grinding unit including new reception, storage and raw material handling systems and two mills. The work is intended to reduce the CO₂ emissions from the plant. France-based Fives FCB previously said that it had won a contract for the project. Commissioning of the new equipment is scheduled for the beginning of 2024.

India: Tamilnadu Cements plans to set up a new grinding plant in Alangulam, Tamil Nadu. The Hindu newspaper has reported that the unit will serve the nearby Arasu cement plant and double its cement capacity to 0.56Mt/yr from 0.28Mt/yr. It will cost US$5.22m and produce the company's Valimai cement.

Tamilnadu Cements has sold 59,000t of Valimai cement to date.

This week’s big story has been that Holcim may be considering selling its business in India. Both the Economic Times newspaper and Bloomberg separately reported that the owner of Ambuja Cement and ACC has been holding early talks with local producers. The discussions have been described as exploratory and an eventual divestment is far from certain. The combined market value of both companies was placed at US$15bn, at the time that the story broke, making it one of the largest potential acquisitions in India. Holcim has refused to comment on the matter.

If it actually happened then the scale of this potential sale would be breathtaking. Holcim has been gradually slimming down since the merger between Lafarge and Holcim in 2015. The big divestments mostly came after the appointment of former Sika boss Jan Jenisch in 2017. Four integrated plants and other assets were sold in Indonesia for US$1.75bn in 2019, a 51% stake in three integrated plants and two grinding plants were sold in Malaysia for US$396m (also in 2019) and five integrated plants were approved for sale in Brazil for US$1.03bn in April 2022.

A complete divestment of Ambuja Cement and ACC in India would see 17 integrated plants and 14 grinding plants being sold with a production capacity of around 66Mt/yr. If any company did buy the lot in one go, at a stroke it would become the second-largest cement producer in the world’s second-largest second market. The nearest acquisition in the last decade that comes close to this was when CRH purchased 24 cement plants with a production capacity of 36Mt/yr from Lafarge and Holcim in 2015 for US$6.5bn.

2022 would certainly be a good time to sell up with both Ambuja Cement and ACC having reported strong sales and earnings figures in 2021 following the coronavirus-related lockdowns in 2020. Performance is even better compared to 2019. Ambuja Cement’s net sales and earnings before taxation, interest, depreciation and amortisation (EBTIDA) grew by 23% year-on-year to US$1.81bn and by 21% to US$420m respectively in 2021. ACC’s sales and operating EBITDA grew by 17% to US$2.07bn and 28% to US$393m respectively in 2021. However, ACC’s net sales growth was much lower compared to that in 2019. Ambuja Cement produced 25.9Mt of cement in 2021 with a production capacity of 31.5Mt giving it a utilisation rate of 82%. ACC produced 26.9Mt of cement in 2021 with a production of 34.5Mt/yr giving it a utilisation rate of 78%. Both of these rates are higher than the national cement sector rates forecast by analysts of up to 64% in the 2022 financial year. The corporate specifics of any sale are that Holcim owns a majority stake in Ambuja Cement, which in turn owns a majority stake in ACC. In other words: buy one, get the other.

One wider question here is whether there are still any companies and investors out there prepared to put money on this scale into a carbon-intensive industry with net-zero deadlines on the way. Ahead of the 2021 United Nations Climate Change Conference (COP26) in November 2021, India’s prime minister Narendra Modi pledged that his country would cut its emissions to net-zero by 2070. There’s plenty of time left to turn a profit, as cement kilns last about 50 years, but the risk of investing in a stranded asset is growing if the targets are honoured or even brought forward. As a recent Intergovernmental Panel on Climate Change (IPCC) report put it, “Cement and concrete are currently overused because they are inexpensive, durable, and ubiquitous, and consumption decisions typically do not give weight to their production emissions.” All of this suggests that buyers might well be more interested in purchasing parts of Holcim’s Indian operations rather than the whole bundle or breaking operations up further down the line. And that’s even before any competition concerns related to any local buyers are considered. Holcim, for its part, has shown with recent divestments, such as its business in Northern Ireland, that it isn’t necessarily against smaller piecemeal divestments. Negotiations, if they are indeed happening, will be closely guarded.

India: ACC’s earnings before taxation, interest, depreciation and amortisation (EBTIDA) fell by 26% year-on-year to US$83.1m in the first quarter of 2022 from US$113m in the same period in 2021. Net sales rose by 3% to US$566m from US$552m. Sales volumes of cement dropped by 3% to 7.71Mt but volumes of ready-mixed concrete grew by 5% to 0.87Mm³. The subsidiary of Ambuja Cement and Holcim said that its costs had been negatively affected by a global rise in fuel costs caused by ‘geopolitical events.’

The cement producer said that its new integrated plant at Ametha in Madhya Pradesh is scheduled to be commissioned in the fourth quarter of 2022. It commissioned an upgrade to its Tikaria grinding plant in Uttar Pradesh in February 2022. Waste heat recovery unit projects at its Jamul and Kymore plants are ‘on track’ and the board of ACC has approved the next phase of similar projects at its Chanda and Wadi plants.

India: Kanodia Cement has commissioned its new Amethi cement plant in Uttar Pradesh. The plant consists of four grinding units spread over an area of 18ha. Indo-Asian News Service has reported that the facility’s equipment includes two 12-spout rotary packers and six floor-mounted truck loading machines, supplied by Denmark-based FLSmidth. Kanodia Cement says that the new plant marks progress in line with its sustainable development plant. Its operations will directly and indirectly employ 1000 people.

Ghana: Denmark-based Investeringsfonden for Udviklingslande (IFU) and Norway-based Norfund have invested US$27.9m in CBI Ghana. The funding will support the cement producer’s upgrade of a clay calcination unit at its 0.6Mt/yr Tema grinding plant in Accra. Denmark-based FLSmidth is supplying the equipment for the project.

Namibia: Immigration authorities have apprehended eight Chinese employees of Whale Rock Cement at the company’s Otjiwarongo grinding plant who failed to produce working permits during an inspection. Namibian Press Agency News has reported that seven of the workers have been in Namibia since mid-2021, while the eighth arrived in March 2022.

African cement producers have confirmed their interest in calcined clay over the last month with two new projects. The big one was announced last week when FLSmidth revealed that it had received an order from CBI Ghana. This follows the launch of a Limestone Calcined Clay (LC3) project in Malawi in mid-March 2022 in conjunction with Lafarge Cement Malawi.

FLSmidth says that its order includes the world’s largest gas suspension calciner system and a complete grinding station. The kit will be installed at CBI Ghana’s plant near Accra in the south of the country. The new clay calciner system is expected to substitute 30 - 40% of the clinker in the final product, resulting in a reduction of up to 40% CO₂/t of blended cement compared to Ordinary Portland Cement (OPC). Overall the equipment manufacturers reckon that the grinding plant will reduce its CO₂ emissions by 20% compared to its current output. There has been no indication of how much the order costs but CBI Ghana expects energy and fuel savings, as well as lower overheads from clinker imports.

The public announcement of the Ghana project was also foreshadowed by the visit of Professor Karen Scrivener to the Ghana Standards Authority in February 2022. This was significant because Scrivener is the head of the Laboratory of Construction Materials at the Ecole Polytechnique Fédérale de Lausanne (EPFL) and has been one of the key instigators of the LC3 initiative since the early 2000s. Other calcined clay cements are available such as Futurecem or polysius activated clay (see below) but LC3 is arguably the most famous given its promotion in developing countries.

The Malawi project is at a much earlier stage. The government launched the public private partnership LC3 project in mid-March 2022 in conjunction with Lafarge Cement Malawi and Terrastone, a brick manufacturer. The Ministry of Mining is currently developing a memorandum of understanding with the Gesellschaft für Internationale Zusammenarbeit (GIZ), a Germany-based development agency. India-based Tara Engineering has also been linked to the scheme.

One thing to note about the Malawi project is that it is the first calcined clay project in the cement industry based in East Africa. All the other African ones are based in West Africa. The other two projects in this region are run by Turkey-based Oyak Çimento and its subsidiary Cimpor. The first of these is a 0.3Mt/yr calcined clay and a 2400t/day cement grinding production line that was commissioned in mid-2020. This plant is based at Abidjan in Ivory Coast. The second is a new plant that Germany-based ThyssenKrupp Industrial Solutions is building for Oyak Çimento at Kribi in Cameroon. This unit has a 720t/day calcined clay and a 2400t/day cement production capacity and it will use the supplier’s ‘polysius activated clay’ technology. ThyssenKrupp’s involvement came to light in early 2020 and commissioning was scheduled for late 2021. However, no update on the state of the project has been issued so far in 2022.

As the above examples show, Sub-Saharan Africa has at least one live calcined clay plant, two plants are being built and there’s one more at the development stage. This puts the region neck-and-neck with Europe, which has a similar mixture of current and developing projects. This column has been covering the wider trend of the growing usage of various types of blended cements recently, particularly in Europe and the US, with slag cements, Portland Limestone Cement (PLC) and more. With PLC, for example, note the transition of another two North American cement plants to PLC this week alone. As for calcined clay cement, it is fascinating to see the focus move to a different part of the world. Several commentators have predicted that the future looks set to be dominated by blended cements using whichever supplementary cementitious material (SCM) is most available for each plant. The growth in calcined clay confirms this view.

UAE: Switzerland-based ABB has carried out an upgrade of the control system for UltraTech Cement subsidiary Star Super Cement at the company's Dubai grinding plant. The supplier says that it installed its ABB Ability 800xA distributed control system (DCS) across three grinding units at the facility. The DCS will communicate between the plant and the company's Ras Al Khaimah clinker plant. ABB previously supplied electric and automation engineering services for the Ras Al Khaimah plant in 2012.

ABB Process Industries global cement lead Max Tschurtschenthaler said that Star Cement's operations will benefit from improved operator visibility, easier maintenance and reduced downtime due to the new systems.
