Italy/The Netherlands: Cementir Holding has appointed the board of directors for the period 2020 - 2022 made up of nine members: Francesco Caltagirone as executive director, with Azzurra Caltagirone, Alessandro Caltagirone, Edoardo Caltagirone, Saverio Caltagirone, Fabio Corsico, Paolo Di Benedetto, Veronica De Romanis and Chiara Mancini, all acting as non-executive directors.

As the holding company is based in the Netherlands, directors Paolo Di Benedetto, Veronica De Romanis and Chiara Mancini have declared that they meet the independence requirements pursuant to the Dutch Self-Discipline Code. The meeting also appointed PricewaterhouseCoopers Accountants NV as auditor for the years 2021 - 2030. Cementir Holding reported a net profit attributable to shareholders of Euro83.7m for 2019.

Cement and concrete products with sustainability credentials have increased in recent years as societies start to demand decarbonisation. In spite of the recent drop in the European Union (EU) Emissions Trading Scheme (ETS) price, there has been a trend in recent years in the construction industry towards offerings with better environmental credentials. Indeed, this week’s position paper from Cembureau on a carbon border mechanism concerns directly the growth of these kinds of products within Europe. Typically, the higher profile projects have been slag cement or concrete implementations such as Hanson’s use of its Regen cement substitute in a London sewer project or David Ball Group’s Cemfree concrete in a road project also in the UK. In this short review we’ll take a selective look at a few of the so-called low carbon cement and concrete products currently available.

Table 1: Some examples of methods to reduce embodied CO₂ in cement and concrete. Note - the product examples are selective. In some cases many other products are available.

Looking at cement first, the easiest way for many producers to bring a lower carbon product to market has been to promote cements made using secondary cementitious materials (SCM) such as granulated blast furnace slag or fly ash. These types of cements have a long history, typically in specialist applications and/or in relation to ease of supply. For example, cement producers in eastern India often manufacture slag cements owing to the number of local steel plants. However, cement producers have more recently started to publicise their environmental credentials as they reduce the clinker factor of the final product. Alongside this though, in Europe especially, a number of so-called low carbon cement producers have appeared on the scene such as EcoCem and Hoffman Green Technologies. These newer producers tend to offer SCM cement products or other low carbon ones built around a grinding model. It is likely that their businesses have benefitted from tightening EU environmental legislation. How far cement producers can pivot to SCM cement products is contentious given that slag and fly ash are finite byproducts of other industries that are also under pressure to decarbonise. Although it should be noted that other SCMs such as pozzolans exist.

As will be seen below a few of the methods to reduce embodied CO₂ in cement and concrete can be used in both materials. SCMs are no exception and hold a long history in concrete usage. As mentioned above David Ball Group sells Cemfree a concrete product that contains no cement. Harsco Environmental, a minerals management company, invested US$3m into Carbicrete, a technology start-up working on a cement-free concrete, in late 2019.

Limestone calcined clay cements are the next set of products that are starting to make an appearance through the work of the Swiss-government backed LC3 project, more commercial offerings like FutureCem from Cementir and H-EVA from Hoffman Green Technologies and today’s announcement about ThyssenKrupp’s plans to fit the Kribi cement plant in Cameroon with its Polysius activated clay system. They too, like SCM cements, reduce the clinker factor of the cement. The downside is that, as in the name, the clay element needs to be calcined requiring capital investment, although LC3 make a strong case in their literature about how fast these costs can be recouped in a variety of scenarios.

Calcium silicate cements offer reduced process emissions by decreasing the lime content of the clinker lowering the amount of CO₂ released and bringing down the temperature required in the kiln to make the clinker. Solidia offers its calcium silicate cement as part of a two-part system with a CO₂ cured concrete. In the US LafargeHolcim used Solidia’s product in a commercial project in mid-2019 at a New Jersey paver and block plant. Solidia’s second core technology is using CO₂ to cure concrete and reducing water usage. They are not alone here as Canada’s CarbonCure Technologies uses CO₂ in a similar way with their technology. In their case they focus more on CO₂ mineralisation. In Germany, Schwenk Zement backed the Celitement project, which developed a hydraulic calcium hydro silicate based product that does not use CO₂ curing. Celitement has since become part of Schwenk Zement.

Solidia isn’t the only company looking at two complementary technologies along the cement-concrete production chain. A number of companies are looking at recycling concrete and demolition waste. Generally this splits into coarse waste that is used as an aggregate substitute in concrete and fine waste that is used to make cement. LafargeHolcim has Evopact for the coarse waste and Susteno for the fine. HeidelbergCement has EcoCrete for the coarse and is researching the use of fines. Closing the loop for heavy building material producers definitely seems like the way to go at the moment and this view is reinforced by the involvement of the two largest multinational producers.

Of the rest of the other low carbon cement methods detailed in table 1 these cover other non-Ordinary Portland Cement (OPC) such as geopolymer and calcium sulphoaluminate cements. The former are a type of alkali activated binder and generally lack common standards. The latter are similar to slag cements in that they are established specialist products with lower CO₂ emissions than OPC.

With concrete when trying to make a low carbon product the first choice is whether to choose a low-carbon cement as the binder or even not to use cement at all in the case of Regen or Cemfree. From here the next step is to simply use less cement in a concrete mixture. There are a number of ways to do this from optimising aggregate gradation, following performance specifications more closely, using strength tests like maturity methods and generally adhering to quality control protocols better to deliver more consistency. Read the Mineral Production Association (MPA) publication Specifying Sustainable Concrete for more detail on this. Using concrete admixtures can also help make concrete more sustainable by improving quality and performance at construction sites through the use of plasticisers and accelerators, by decreasing embodied carbon through the use of water reducers and by improving the whole life performance of concretes. The use of locally-sourced aggregates is also worth noting here since it can reduce associated transport CO₂ emissions.

More novel methods of reducing embodied CO₂ emissions in concrete include the use of geopolymer concrete in the case of Zeobond Group’s E-Crete or adding graphene as Concrene does. Like geopolymer cements, geopolymer concretes are relatively new and lack common standards. Products like Concrene, meanwhile, remain currently at the startup level. Finally, if all else fails, offsetting the CO₂ released by a cement or concrete product is always an option. This is what Cemex has done with its Vertua Ultra Zero product. The first 70% reduction in embodied CO₂ is gained through the use of geopolymer cement. Then the remaining 30% reduction is achieved through a carbon offsetting scheme via a carbon neutral certification verified by the Carbon Trust.

As can be seen, a variety of methods exist for cement and concrete producers to reduce the embodied CO₂ of their products and call them ‘low-carbon.’ For the moment most remain in the ‘novelty section’ but as legislators promote and specifiers look for sustainable construction they continue to become more mainstream. What has been interesting to note from this short study is that some companies are looking at multiple solutions along the production and supply chain whilst others are concentrating on single ones. The companies looking at multiple methods range from the biggest building material producers like LafargeHolcim and HeidelbergCement to smaller newer ones like Solidia and Hoffman Green Technologies. Also of note is that many of these products have existed already in various forms for a long time like SCM cements and concretes or the many ways concretes can be made more sustainable through much simpler ways such as changing aggregate sourcing or working more efficiently. In many cases once markets receive sufficient stimulus it seems likely that low carbon cement and concrete products will proliferate.

Italy: Cementir Holding, a Caltagirone Group company, closed 2019 with revenues of Euro1.21bn, according to the consolidated preliminary results examined yesterday by the board of directors chaired by Francesco Caltagirone Jr. This represents a year-on-year rise of 1.2% compared to 2018.

Cementir’s gross operating margin grew by 10.6% to Euro263.8m. Cement and clinker volumes, however, fell by 3.4% to 9.5Mt. On a like-for-like basis, cement and clinker sales were down 5%. The company attributed this to a ‘negative trend’ in Turkey, partially balanced by the positive performance of Belgium and Denmark. Ready mixed concrete sales also fell due to the effects of the Turkish economy. Overall ready mixed concrete sales fell to 4.1Mm3/yr, a drop of 16.4% year-on-year.

UK: The Global Cement and Concrete Association (GCCA) has launched ‘Innovandi,’ a research network between industry and scientific institutions. The network intends to research the areas of process technology, including the impact of co-processing, efficiency of clinker production and implementation of CCUS/ technologies, and products. This will include the impact of clinker substitutes and alternative binders in concrete, low carbon concrete technology and improve the understanding of CO₂ reduction through re-carbonation.

“Our industry is fully committed to taking action to reduce CO₂ emissions. As such, Innovandi is an industry led initiative and will bring together the best minds from all corners of the cement and concrete world, academia and business. Together we will truly collaborate on a global scale and use our expertise to find new ways of working and developing effective innovations,” said Benjamin Sporton, the chief executive officer (CEO) of the GCCA.

24 companies from the cement and concrete industry, including cement and concrete manufacturers, admixture specialists and equipment suppliers, have committed to the initiative, with scientific institutions and additional companies set to join as its work begins work. These include Buzzi Unicem, Cementir Holding, Cementos Argos, Cementos Molins, Cementos Pacasmayo, Cemento Progresso, Cemex, CNBM, Chryso, CRH, Dalmia Cement, FLSmidth, Grupo Cementos de Chihuahua (GCC), GCP Applied Technologies, Mapei, HeidelbergCement, LafargeHolcim, Nesher Israel Enterprises, SCG Cement, Titan Cement, Refratechnik Cement, Sika Technology, Subote New Materials and Votorantim.

As part of the new initiative, the GCCA also intends to establish an annual Innovandi global conference to promote collaboration on innovation and research in the sector.

Netherlands: Cementir Holding has moved its registered office to the Netherlands. The building materials producer approved the decision in late June 2019. The transfer will not affect the company’s listing on the Italian Stock Exchange or its tax residence, which will remain in Italy. At the time chairman Francesco Caltagirone, Jr said that the decision to move the company’s headquarters was a, “purely technical choice that in no way disregards our group's deep Italian roots.”

Cementir Holding is a multinational manufacturer of grey and white cement, ready-mixed concrete, aggregates and concrete products, exporting to over 70 countries worldwide. It is a global leader in white cement and the group employs approximately 3100 people in 18 countries. The group sold its principal Italian business, Cementir Italia, and its shares in related companies to Italcementi in early 2018.

Italy: Cementir Holding has blamed poor performance in Turkey for falling cement sales volumes. Although it said that positive trends in Scandinavia, the Baltics and Belgium had party compensated for this. Its sales volumes of grey and white cement fell by 12.2% year-on-year to 4.32Mt in the first half of 2019 from 4.92Mt in the same period in 2018. Ready-mixed concrete sales dropped by 21.3% to 2Mm³ from 2.54Mm³. Its revenue rose slightly by 0.6% to Euro592m from Euro589m. Its earnings before interest, taxation, depreciation and amortisation (EBITDA) grew by 14.7% to Euro110m from Euro96m.

Charah Solutions has been steadily building up its fly ash distribution business in recent years with an eye on the supplementary cementitious materials (SCM) market. This week it opened the third of its new series of SCM grinding plants, at Oxnard in California, US. The unit sticks out because it is focusing on grinding natural pozzolans. The plant will receive natural pozzolan by truck and rail and then use Charah’s patented grinding technology to produce pozzolan marketed under its MultiPozz brand. The previous plants in this series mentioned natural pozzolans but this is the first to promote it explicitly.

The change is potentially telling because global demand for granulated blast furnace slag (GBFS) outstrips supply. Both performance benefits and environmental regulations are pushing this. It’s a similar situation for fly ash, also driven by trends to close coal-fired power stations in some countries. As Charles Zeynel of SCM trading firm ZAG International explained in the March 2019 issue of Global Cement Magazine, “...volcanic pozzolans are a potential SCM of the future. This is gaining traction, but it’s slow progress at the moment. This will be the answer for some users in some locations.”

The problem though is that natural pozzolans are down the list of preferred SCMs for their chemical properties after silica fume, GBFS and fly ash. The first is expensive but the latter two were traditionally cheap and easy to obtain if a cement or concrete producer had access to a source or a distribution network. Natural pozzolans are very much subject to variations in availability.

It’s no surprise then that Charah is promoting natural pozzolans in a Californian plant given that state’s environmental stance. It’s unclear where Charah is sourcing their pozzolan from but they are not the only company thinking about this in the US. Sunrise Resources, for example, is working on the environmental permits for a natural pozzolan mine near Tonopah in Nevada. As it described in its company presentation, California and Nevada are the most affected states in the fly ash supply crisis because they are, “...at the end of the line when it comes to rail deliveries from power stations in central and eastern USA.” It also estimated that California used 0.9Mt of pozzolan in its cement production of which about 90% is fly ash. The state produced 9.6Mt in 2015. Other companies are also mining and distributing natural pozzolans in the US as the website for the National Pozzolan Association (NPA) lists. Although, if this line-up is comprehensive, then the field is still fairly select. Most of these companies are based in the west of the country.

One last thing to consider is that various groups are tackling a potential future lack of SCMs for the cement industry by making their own pozzolanic materials through the use of calcined clay. These groups include the Swiss-government backed LC3 project and Cementir’s Futurecem products. Using clay should bypass the supply issues with natural pozzolans but the cost of calcining it requires at the very least an investment to get started.

As concrete enthusiasts often point out, a variant of pozzolanic concrete was used by the Romans to build many of their iconic structures, some of which survive to the present day. To give the last word to the NPA, “What is old is new again: natural pozzolan is back!” If environmental trends continue and steel and coal plants continue to be shut then it might just be right.

Italy: Cementir Holding’s sales revenue fell by 4.2% in 2018 on a like-for-like basis due to poor performance in Egypt and Norway. Military operations in the Sinai impacted production in Egypt between February and May 2018 and bad weather in Norway affected the first quarter. However, it noted good results in Malaysia, Belgium and China.

On an adjusted basis its revenue rose by 4.9% to Euro1.2bn from Euro1.14bn. Earnings before interest, taxation, depreciation and amortisation (EBITDA) grew by 7.1% to Euro239m from Euro223m. Grey and white cement sales volumes fell by 4.4% to 9.8Mt from 10.3Mt. Ready-mixed concrete volumes fell slightly to 4.9Mm³.

Italy: Cementir’s sales and earnings have benefited from new assets in the US as well as good performance in Belgium and China. Its sales revenue rose by 4.8% year-on-year to Euro893m in the first nine months of 2018 from Euro852m in the same period in 2017. Its earnings before interest, taxation, depreciation and amortisation (EBITDA) increased by 5.2% to Euro163m from Euro155m. Its cement sales volumes fell by 1.8% to 7.52Mt from 7.66Mt. However, these figures take into account the company’s sale of its Italian operations.

Francesco Caltagirone Jr, chairman and chief executive officer, said, “In the first nine months of 2018 the EBITDA benefited on the one hand from the contribution of the US by Euro12.3m and from the improvement in Belgium and China, on the other it suffered the deterioration of earnings in Egypt due to the curfew introduced in February 2018 and the resulting stop of all transport activities until May 2018, in Norway due to bad weather in the first quarter, and in Turkey due to the economic and currency crisis getting worse in the month of August.”

In March 2018 the company purchased a controlling stake in Lehigh White Cement in the US from HeidlebergCement. It operates the company with Cemex as a junior partner. In October 2018 Cementir, through its subsidiaries, acquired an additional stake in Egypt’s Sinai White Cement increasing its share to 71.1% from 66.4% for Euro3.8m.

Italy: Cementir Holding’s net profit rose to Euro77m in the first half of 2018, a massive 400.5% increase compared to just Euro15.5m in the first half of 2017. Revenues increased by 5.7% to Euro588.5m from Euro556.9m in the first half of 2017. Earnings before interest, tax, depreciation and amortisation (EBITDA) improved by 9.5% to Euro96m from Euro87.7m in the first half of 2017. The impact of the devaluation of the main foreign currencies against the Euro on the gross operating margin had a negative effect of Euro7.9m. At constant exchange rates, EBITDA in 2017 would have amounted to Euro103.9m.

Chairman and CEO Francesco Caltagirone Jr explained that the results were up compared to the first half of 2017 also on a like-for-like basis, without the effect of the acquisition of Lehigh White Cement Company in the United States. The improvement in the gross operating margins in Turkey, Belgium and China, offset the worsening results in Egypt, Norway, Malaysia and Denmark. The results were also negatively affected the unfavourable winter weather conditions in the first quarter in Scandinavia and Belgium, as well as the earlier timing of Ramadan in Turkey and Egypt.
