France: UK-based Carbon8 Systems has announced plans for the commercial implementation of its carbon capture and use (CCU) system at Vicat’s Montalieu integrated cement plant in France. It follows successful demonstration projects at cement plants in the UK and Canada.

The company’s CO₂ntainer product will be deployed directly onsite at the plant and integrated into Vicat's existing industrial processes. It will capture CO₂ directly from the plant's flue gas emissions and use this as part of its Accelerated Carbonisation Technology (ACT) process. This accelerates the carbonation of cement bypass dust into lightweight aggregates. In its first phase of operation it will process and convert up to 12,000t of cement bypass dust.

US: Vicat subsidiary National Cement has received a fine of US$148,000 from the Alabama Department of Environmental Management (ADEM) for exceeding mercury emissions regulations over a 123-day period between May 2019 and February 2020 at its integrated Ragland plant in Alabama. The Daily Home newspaper has reported that unexpectedly high mercury levels in coal and other raw materials burned as fuel during that time caused the breach, which the company immediately reported to ADEM.

National Cement president Spencer Weitman said, “The issue took several months to fix.” Multiple upgrades and operational changes solved the issue, including installation of a US$400,000 mercury absorption carbon injection system. ADEM said, “National Cement did not economically benefit from the emissions violations.”

In January 2020 National Cement began work on construction of a new US$250m kiln line, due for completion in 2022.

France: Vicat says that group business activity increased month-on-month between April and May 2020. In a special update on business in the context of the coronavirus, the company said that the outbreak’s impacts varied across the 12 countries in which it operates, all of which locked down due to the pandemic.

In France, the level of business is “slightly lower” than in May 2019 following a steady recovery from a “strong slowdown in mid-March 2020.” Macroeconomic and competition issues continue in Egypt and Turkey, not however due to the coronavirus outbreak, while volumes and prices have generally increased in Switzerland, the US, Brazil and Western Africa, except in Senegal, where the government has cancelled infrastructure projects. Following the pan-Indian lockdown between 24 March 2020 and 17 April 2020, business in India has resumed, albeit at a “level significantly below that of the same period of 2019.”

The group says that it is planning cost-cutting measures and has postponed a planned US price rise to late 2020.

Many of the first quarter financial results are in from the multinational cement producers and a few points are worth discussing. As usual a few caveats are worth mentioning such as seasonal and geographical variations between companies, such as producers in the northern hemisphere experiencing a generally slower period. It’s also worth noting that this is a selective look at some of the larger cement producers as not all of them release detailed figures at this stage and others have been delayed. However, the economic effects of the coronavirus lockdowns are clearly showing an effect in a kind of wave as the pandemic has spread.

Graph 1 above shows the effects of the earlier lockdown in China upon the results of the Chinese producers like CNBM, Anhui Conch and China Resources Cement (CRC). What’s interesting with these companies is that they have all suffered revenue hits of 20 – 25%. Huaxin Cement, a producer based in Hubei province near Wuhan where the Chinese lockdown was strictest, is not shown in Graph 1 but its revenue fell by 35% in the first quarter. See GCW452 for more on coronavirus effects on the Chinese cement industry.

Looking more widely, both LafargeHolcim and HeidelbergCement suffered declines of around 10%. This is somewhat misleading as both companies are constantly selling assets making the like-for-like results not quite as bad, particularly in the case of LafargeHolcim with its South-East Asian divestments. Although note this week that LafargeHolcim’s deal to sell its majority stake in Holcim Philippines lapsed this week due to the local competition regulator not granting permission in time. Yet, they are also beneficiaries and victims to an extent of their wide geographical spread with worse performance in Asia and better results in North America. For a fuller look at LafargeHolcim’s first quarter results see last week’s column. The rest of the producers featured generally reflect their tighter market spread with Buzzi Unicem particularly benefiting from the relatively untouched market in the US. Shree Cement, an Indian producer, escaped relatively unscathed, possibly as the Indian lockdown only started in late March 2020. All eyes will be on the results of UltraTech Cement, the largest producer in India, when they finally emerge.

Cement sales volumes tell a similar story, although a few different companies are featured in Graph 2. Note CRC’s year-on-year fall of 26% to 11.2Mt in the first quarter. It’s the only larger Chinese cement producer that we’ve found so far that has released sales volumes. Semen Indonesia is interesting too because its figures jumped in January 2020 as its acquisition of Holcim Indonesia only went on the books in February 2019. It’s February and March sales volumes have each been 4 - 5% down year-on-year but it’s far from clear whether this is due to general production overcapacity in the country or from the global health crisis. Despite this, its export volumes from both the mainland and its TLCC subsidiary in Vietnam have held up well. Unfortunately though, its performance in Vietnam may be an outlier if data from the General Department of Vietnam Customs is to be believed this week. It indicated that overall cement exports from the country fell by 9.7% year-on-year to 7.73Mt in the first quarter of 2020. Cementos Argos is also worth looking at as it suffered from the government lockdown in Colombia despite having an international presence in the Caribbean and the US.

Most of the world’s largest cement producers are preparing for the economic shockwaves from lockdowns to hit balance sheets in the second quarter of 2020. Many have said exactly this and have paraded their liquidity levels in preparation. Alongside this the results of the Chinese producers in the next quarter may offer some light on what kind of recovery is possible from easing lockdown measures. Yet the risk of second waves of infections from coronavirus potentially jeopardises any kind of fast or easy recovery without a vaccine. Today’s news that Cemex is considering mothballing its integrated plant at South Ferriby in the UK has been blamed on an analysis of the company’s European cement supply chain. The company says it is not related to coronoavirus but it does suggest the company is making savings.

This week has seen international press coverage return to Wuhan, China and South Korea where small numbers of infections have started to build despite being thought mostly eradicated. No one wants the so-called ‘W’ economic recovery with its rollercoaster ride of crests and dips or indeed the ‘L’ with its slow tail of recovery. Yet, for better or for worse, some form of normality has to return after the lockdowns end. The UK, for example, the country with the worst death rate from coronanvirus in Europe, has allowed its construction workers to pick up tools this week. If and when they can do so in the UK and everywhere else without causing the basic reproduction number (R₀) to rise then the future starts to look a little brighter.

France: Vicat has reported first-quarter sales of Euro615m in 2020, up by 7% year-on-year from Euro600m in the first quarter of 2019. Cement sales grew by 5.5% to Euro319m (52% of total sales), up by 5.5% year-on-year from Euro302m.

Vicat chair and CEO Guy Sidos said, “The Group's performance over the first quarter of 2020 was solid despite a sharp slowdown at the end of the period in France, India and Italy.” In spite of the coronavirus crisis, “Industrial and commercial activity was maintained on almost all sites, in line with market evolutions.” Sidos says that the group expects ‘a significant impact on first-half results’ in 2020.

There was fantastic news for fans of novel cements this week, when Cementos Argos announced the completion of work on a new 0.45Mt/yr calcined clay production line at its Rio Claro plant in Colombia. This artificial pozzolanic material, developed and promoted by the Swiss-led LC3 consortium in recent years, can dramatically lower cement CO₂ emissions by replacing slag and/or fly ash in cement mixes. The Rio Claro plant is the first major cement plant to install such a line following smaller trials in Switzerland, India and Cuba.

Suitable clays are more widely available than slag and fly ash, alleviating some of the difficulty and cost of obtaining supplementary cementitious materials. They also need to be calcined at just 800°C, offering massive savings in terms of fuel costs, CO₂ emissions and embodied energy compared to Ordinary Portland Cement (OPC) production. Karen Scrivener from the École Polytechnique Fédérale de Lausanne (EPFL), the leading academic party in the LC3 consortium, explained that calcined clays are at their best when in ternary (three-way) blends alongside clinker and limestone in the September 2019 issue of Global Cement Magazine. “It has long been known that calcined clays can be pozzolanic,” she explained. “When used alone, the maximum substitution level is around 30%, which gives a moderate saving in CO₂ emissions. However, if we substitute a further 15% of the clinker with limestone, we get a significant reduction in CO₂ emissions, with a product that has almost identical properties to the blend that contains just the calcined clay.”

While the exact composition of Rio Claro’s new products is unclear, it will enable Cementos Argos to produce ternary cement blends with CO₂ emissions 38% lower than OPC. Energy consumption is also cut by 30%, which provides secondary benefits in terms of reduced off-site CO₂ emissions. At the plant’s launch, Cementos Argos’ President Juan Esteban Calle clearly stated that calcined clays were the way forward, announcing, “With this project we are sowing the seeds of the Argos of the future. It starts today with a new production line at Rio Claro. In our commitment to climate change, this project makes us very proud.”

The response from Argos’ consumers will be keenly watched, especially in Europe. Just this week LafargeHolcim and Vicat, along with France’s Technical Association of the Hydraulic Binders Industry (ATILH), called on the European Commission and European Committee for Standardisation to hurry up and publish ternary cement standards across the European Union (EU). At the moment these producers are primarily concerned with CEMII / C-M and CEM VI cements. These classes of cement comprise a range of ternary blends that contain clinker and limestone, plus a third component, be it slag, fly ash, natural pozzolans or calcined clay. They claim that placing low-clinker cements on the market could reduce the amount of CO₂ emitted by 127kg/t, around 20% of the 656kg/t average in Europe at present.

Frustrated with the delays at Commission level, cement producers have now taken things into their own hands. The plan is to establish the same standard within each EU Member State at the national level, rather than waiting in vain for standards from ‘on high.’ One pressing driver for this behaviour is the rapid approach of the Phase 4 of the EU Emissions Trading Scheme (ETS) in January 2021. In Phase 4 it is likely that EU cement producers will be allocated only 80% of the free allowances they have become accustomed to. They will have to buy the remainder at market prices, currently Euro25.1/t of CO₂ (17 February 2020). This will represent a massive new expense for some producers. The opportunity to sell cement that emits only 58% of the CO₂ of OPC is clearly exceedingly attractive as a way to reduce outgoings. CO₂ emissions will be reduced, of course but, as usual, the way to make companies do things is to hit them in the wallet.

Indeed, on this point, Vicat seemed to almost goad or ‘troll’ its competitors in Europe this week by announcing that it has never sold any EU ETS allowances and is sitting atop a 5Mt CO₂ reserve worth Euro120m. This is sufficient to last it until 2030 at current prices. The key part of that last sentence is ‘current prices,’ which are subject to change. In its press release, Vicat was keen to point out that it is not resting on its laurels, highlighted by its advocacy for ternary blends and continued development of alternative fuels. This may be wise, considering that EU ETS allowances will likely cost more once Phase 4 kicks in.

With clinker factors of just 50 - 65% for CEMII / C-M, and 35 - 50% for CEM VI, Edelio Bermejo, director of research and development (R&D) at LafargeHolcim insists, "These cements are no longer at the research and development stage. They have been widely validated and we are ready to produce them, especially as their manufacture does not require modification of our facilities." The establishment of Cementos Argos’ Rio Claro calcined clay plant proves his point. We can expect to hear a lot more about these blends in the coming months. In the words of Bermejo, “The future is here!”

EU: Researchers from LafargeHolcim, Vicat and the Technical Association of the Hydraulic Binders Industry (ATILH), have called for harmonised European standards to enable the introduction of ternary cement blends such as CEM II C-M and CEM VI, which comprise clinker, limestone and supplementary cementitious materials, most commonly slag and fly ash, so that the European cement sector can lower its CO2 emissions. "It’s a very powerful short-term lever," said Fabrice Copin, director of the industrial process at ATILH.

The roadmap for achieving carbon neutrality in 2050, established by the industry in 2018, makes the development of new cements a priority. Placing low-clinker cements on the market could reduce the amount of CO2 emitted by 127kg/t, around 20% of the 656kg/t average in Europe at present.

With clinker factors of just 50-65% for CEMII / C-M, and 35-50% for CEM VI, Edelio Bermejo, director of research and development (R&D) at LafargeHolcim insists, "These cements are no longer at the R&D stage. They have been widely validated and we are ready to produce them, especially as their manufacture does not require modification of our facilities."

However, these new cements cannot be widely sold and used due to a legal deadlock at the European Commission level that hinders their approval, according to Xavier Guillot, the manager of standards coordination at LafargeHolcim. “To introduce them, the harmonised European standard which authorises their placing on the market must be revised,” said Guillot. “However, legal problems between the European Commission and the European Committee for Standardisation prevent the work from being finalised. The cement manufacturers are considering drafting a standard common to all member states, but which would be applied at a national level within each member state. We have to move forward to face the challenges we are asked to answer, namely reducing our CO2 emissions.”

One of the limits of CEM II / C-M and CEM VI cements is the availability of substitutes used to replace clinker which are clustered around other industrial sites such as steel plants and coal-fired power stations. "In the future, with an increase in the recycling of steel and possible relocations of steel mills, the deposits are likely to move away from our markets and to diminish,” said Laury Barnes, Vicat’s scientific director. “In addition, the current availability of slag will not cover all the needs for low-carbon cements. Likewise for the fly ash, which should become increasingly rare as the thermal power plants close.”

Barnes instead advocates calcined clays as a suitable replacement for slag and fly ash. "Clays are minerals found everywhere on Earth,” says Barnes, who, like Bermajo, advocates the use of LC3 cement blends being developed by a Swiss-Indian-Cuban consortium. These contain clay that has been heated to 800°C instead of slag or fly ash.

France: French press has reported that Vicat, the last remaining cement producer in French hands, has accumulated a large stockpile of EU Emissions Trading Scheme (ETS) credits, sufficient to last it until 2030. It says that this makes it unique among cement producers covered by the scheme. It has never sold any of the credits that it was over-allocated in the first three stages of the ETS. It is thought that this will put it at a competitive advantage from the start of stage 4 in January 2021, when free allowances for the sector will become significantly scarcer.

Vicat has a stock of credits that represent 5Mt of CO₂, valued at Euro120m at the current market price. "It covers our activity in France and Switzerland and we will still be in a surplus position in 2030. We are entering the next European regulatory phase in a good condition," said CEO Guy Sidos.

Vicat is keen to point out that this does not mean it is complacent or will pollute at all costs. "At the end of 2019, we reduced our CO₂ emissions by 15% compared to 1990. The objective is a further decrease of 13% between today and 2030," explained Sidos.

France: Vicat’s sales were reduced in 2019 by poor markets in Turkey and, to a lesser extent, Switzerland and Egypt. Its sales fell by 1% year-on-year to Euro2.74bn in 2019 from Euro2.58bn at constant scope and exchange rates. Its cement sales volumes dropped by 2% to 22.4Mt from 22.8Mt but its concrete volumes grew by 1.1% to 9.1Mm³ from 9.0Mm³. Its earnings before interest, taxation, depreciation and amortisation (EBITDA) decreased slightly to Euro156m.

“Strong growth in France, the US, Africa and Kazakhstan helped offset difficult market conditions in Turkey and Egypt. Furthermore, in line with our strategy of targeted acquisitions, the purchase of Ciplan in Brazil, in January 2019, allowed the group to continue its international growth in a region offering strong potential by integrating teams and assets of the highest quality,” said chairman and chief executive officer (CEO) Guy Sidos.

The group performed well in France, the US and Italy, especially due to the acquisition of Ciplan in Brazil. Sales in Turkey suffered from a generally poor economic situation. Competition in Egypt and a downturn in the precast concrete market in Switzerland caused problems in these countries respectively.

US: National Cement has broken ground on its US$250m upgrade to the Ragland plant in Alabama. City, county and state officials attended the ceremony, according to WBRC. The subsidiary of France’s Vicat is building a second kiln at its 1.9Mt/yr plant in Alabama. The project is expected to be completed in 2022.
