UK: The Mineral Products Association (MPA) has endorsed the UK government's commitment to finance the country’s first carbon capture, utilisation and storage (CCUS) sites, which could help make the creation of the nation's first net zero cement plant a reality. One of the projects hoping to receive funding is Heidelberg Materials’ Padeswood Cement Works in Flintshire, part of the HyNet North West cluster of industrial sites poised to implement CCUS. The government's support for CCUS not only progresses the decarbonisation efforts of the UK concrete, cement, and lime sectors, but also reduces the pressure to import cement from overseas, protecting the UK economy by sustaining local industry and jobs.

MPA executive director for energy and climate change Diana Casey, said “It is very positive to see the Government’s commitment to two carbon capture clusters and this news provides an important signal of intent to businesses and the investor community. While we await the specific detail of the package of support, the support announced for the HyNet cluster creates an opportunity to bring forward the UK’s first cement carbon capture plant.”

UK: A new study by the Mineral Products Association (MPA), supported by Innovate UK, has found that incorporating reclaimed clays and finely ground brick powder into cement production can reportedly lower the embodied CO₂ by up to 3%. The materials are used as calcined clay in the cement production process. The project aims to offer a viable alternative to fly ash and ground granulated blast-furnace slag, as resources diminish due to the steel industry's decarbonisation efforts.

MPA director Diana Casey said "Using discarded bricks and reclaimed clays will not only lower carbon and reduce the amount of materials sent to landfill but has the potential to create a whole new market if these clays become widely used in the construction industry, helping to retain economic value in the UK, secure jobs and attract investment."

UK: Jon Prichard has resigned as the CEO of the Mineral Products Association (MPA) with immediate effect. He announced in late July 2024 that he was stepping down for personal reasons. He started in the post in October 2022. The MPA has established an executive management committee (EMC) as an interim measure to take responsibility for the ongoing and effective management of the organisation. This will be chaired by Lex Russell in his capacity as MPA chair, supported by MPA’s two executive directors, Diana Casey and Mark Russell, and MPA advisor Chris Leese.

The Hillhead Quarrying, Construction and Recycling Show is in full flow this week, taking place near Buxton in Derbyshire. As one delegate marvelled on the panoramic minibus journey down to the quarry, “It’s like a music festival without the music and… other stuff.” Indeed. Of course what one doesn’t find at Glastonbury and the like is a near comprehensive range of suppliers, over 600 of them, to the industry all in one place… in a quarry! Where else can one get up close and see the new hydrogen-powered generators and excavating vehicles that are being piloted? The official attendance figures don’t get released until after the event but on the ground it looks as busy as ever. It’s truly the place to be this week.

The show gives us a reason to take a look at the UK cement sector. Like many other countries around the world it is an election year in the UK, with a General Election scheduled for 4 July 2024. The result of this should determine the next Prime Minister and the ruling party. So, naturally, the MPA, the trade association for the aggregates, asphalt, cement, concrete, dimension stone, lime, mortar and industrial sand industries, is taking the opportunity to remind the political parties what its priorities are. The quick version is: support for decarbonisation; a streamlined planning system; and better delivery of projects. This sounds familiar to priorities in other countries but one British spin on this includes the UK’s carbon border adjustment mechanism (CBAM).

Edwin Trout’s feature on the UK cement sector in the June 2024 issue of Global Cement Magazine presents a good overview of the last 12 months. The general UK economy has faced shocks in recent years such as Brexit, Covid-19 and the war in Ukraine. However, this has been further compounded by a downturn and high interest rates since late 2022 when the then Prime Minister Liz Truss caused market turbulence in the wake of a badly received government financial statement. As Trout relates, sales of heavy building materials have been in relative decline since mid-2022 with more of the same expected in 2024. Production of cement in 2023 is currently uncertain given the reporting time lag from the MPA but up until 2022 domestic cement sales fell somewhat but imports grew. This has created a situation where overall cement sales in 2022 were 12Mt, not far behind the annual level in the early 2000s. However, the share of imports has nearly doubled since then. More recent MPA data on mortar and ready-mixed concrete sales throughout the first nine months of 2023 suggest that market activity has decreased and poor weather at the start of 2024 looks set to have made this worse.

Despite the apparent slowdown in building materials sales the cement companies have been conducting smaller-scale maintenance and upgrade projects at their facilities and supply chain schemes such as the cement storage unit for deep sea shipping lines that Aggregate Industries said in February 2024 it was going to build at the Port of Southampton. The news the cement companies want to show off has been a steady stream of information about ongoing decarbonisation projects in the cement sector. C-Capture started a carbon capture trial at Heidelberg Materials’ Ketton cement works in Rutland in May 2024, Capsol Technologies said in March 2024 that it had been selected to conduct a study on its carbon capture technology at Aggregate Industries Cauldon cement plant in Staffordshire, Heidelberg Materials' Ribblesdale cement plant in Lancashire announced in March 2024 that it was taking part in a study to assess the use of ammonia as a hydrogen source for fuelling cement kilns and Heidelberg Materials awarded Japan-based Mitsubishi Heavy Industries (MHI) a front end engineering design contract for a carbon capture installation at its Padeswood cement plant in Flintshire in February 2024. Finally, on the divestment front, CRH completed the sale of its UK-based lime business to SigmaRoc for €155m in March 2024. The business operates from sites in Tunstead and Hindlow with five permitted lime kilns.

That’s it for this short recap on the UK for now. For a longer look at the UK cement sector read Edwin Trout’s feature in June 2024 issue of Global Cement Magazine.

Argos Honduras revealed this week that it has been testing the injection of hydrogen into the kiln of its integrated Piedras Azules cement plant. It has completed a pilot with Portugal-based company UTIS. As part of the process it has been trialling, it has split water by electrolysis and then injected the hydrogen and oxygen directly into the kiln via the main burner. The pilot has reportedly increased clinker production and reduced petcoke consumption at the plant.

Argos is far from alone in using hydrogen in this way. At the end of August 2022 Cemex said that it was also starting to use hydrogen at its San Pedro de Macorís cement plant in the Dominican Republic. CRH UK-subsidiary Tarmac completed a trial in July 2022 using hydrogen as an alternative to natural gas at its Tunstead lime plant. HeidelbergCement UK-subsidiary Hanson also ran a successful trial using hydrogen as part of the fuel mix at its Ribblesdale cement plant in 2021. The government-funded trial used a combination of hydrogen (39%), meat and bone meal (12%) and glycerine (49%) to reach a 100% alternative fuels substitution rate. In 2021 Hanson reported that fuel switching to hydrogen could help it reduce its 2050 CO₂ emissions by about 3%, or by -35kg CO₂/t of cement product.

Cemex appears to be a leader in using hydrogen in this way. The Mexico-based company started injecting hydrogen in 2019 and retrofitted all of its European cement plants with the technology to do so in 2020. It then said it wanted to roll this out to the rest of its operations. The project in the Dominican Republic is an example of this. In February 2022 it announced an investment in HiiROC, a UK-based company that has developed a method using thermal plasma electrolysis to convert biomethane, flare gas, or natural gas into hydrogen. The stated aim of this investment was to increase Cemex's hydrogen injection capacity in its cement kilns and to increase its alternative fuel substitution rate. Back in 2020 Cemex said that it planned to use hydrogen injection to contribute 5% of its progress towards its 2030 CO₂ emissions reduction target along with other measures such as increasing its thermal substitution rate and reducing its clinker factor.

As can be seen above there are a number of examples of hydrogen injection being used in cement plants in Europe and the Americas. However, there is very little actual data available publicly at this stage on how much hydrogen that the plants are actually using. For example, Cemex may have hydrogen injection equipment installed at all of its plants in Europe but it is unclear how many plants are actually using it. This is understandable though, given how commercially sensitive the fuel mix of a cement plant is and in Cemex’s case if it wishes to maintain a leader’s advantage in using a new technology.

It is interesting to see, in what has been released so far, the focus on doing deals with companies that supply electrolysis technology such as HiiROC and UTIS. A feasibility study ahead of the Hanson trial at Ribblesdale by the MPA, Cinar and the VDZ suggested that upgrading a kiln burner and adding all the necessary hydrogen storage and pipework could cost at least Euro400,000. However, this study also pointed out that the cost of hydrogen made a big difference to the cost of the CO₂ saving from using it as an alternative fuel. Hence the focus on the technology partners. It will be interesting to see how many more hydrogen injection projects are announced in the coming months and years and, crucially, who is providing the technology to supply the hydrogen.

For more information on the use of hydrogen in cement production see the proceedings from the 15th Global CemFuels Conference & Exhibition where presentations on the topic were given by Cemex and the VDZ

Cembureau called for urgent action on electricity prices from European governments this week to protect cement plants. Its maths was crushingly simple. One tonne of cement takes around 110kWh of electricity to produce. Electricity prices started to top Euro700mWh in some European Union (EU) countries at the end of August 2022. The association says that this represents added costs of Euro70/t of cement and a tripling of the total cost of production. This kind of sudden extra cost to cement production could lead to the widespread closure of cement plants and lead to chaos in the construction supply chain.

Previously, Cembureau reported in 2020 that electricity accounts for about 12% of a cement plant’s energy mix. In a dry production process plant 43% of this is used for cement grinding, 25% goes into raw material preparation, another 25% on clinker production and the final portion is typically used for raw material extraction, fuel grinding and for packing and loading. However, the cost of the electricity can make a big difference to the overall energy bill for a cement plant. When a report by the European Commission’s (EC) Joint Research Centre (JRC) modelled a reference northern European cement plant with a production capacity of 1.0Mt/yr back in 2016, it concluded that the EU cement industry was spending around half of its energy costs on electricity compared to smaller ratios at plants in China, Egypt, Algeria and... Ukraine. That last country in the list is poignant given its unwitting participation in the current energy crisis. One other thing to note is that cement producers, as large scale users, may well be paying less than the wholesale prices Cembureau appears to be quoting.

The timing of Cembureau’s proclamation is pertinent because the EU and individual states have mostly been waiting until the autumn before revealing their energy support plans. However, the dilemma for Cembureau, and other industry lobbying groups, is how to protect their sectors whilst domestic consumers are threatened. The aftermath of the coronavirus lockdowns has shown what can happen when production of key commodities stops: supply chain disruption, shortages and price rises. One ironic shortage in the UK during the lockdown periods was that of CO₂, as high gas prices forced the main producer to shut down, leading to unexpected knock-on problems along the supply chain in areas such as food production. The same situation is reportedly at risk of happening again now too.

Cembureau’s wider solution is to link domestic and industrial consumers of electricity. So, some of its suggestions to policymakers are to use all available means of power generation, implement emergency measures such as price caps immediately, change the rules of the electricity market more generally to prevent future price shocks and to promote large scale renewable power source development. These are all things that could help both individual and industrial users of electricity.

Compare and contrast, then, with the MPA’s (Mineral Products Association) approach to the same problem in the UK. Its strategy instead has been to ask the UK government for tax cuts and freezes and to hurry along the forthcoming policy on support for Energy Intensive Industries. That’s not to say that Cembureau’s suggestions don’t also include some sector specific requests. It has asked that the EU temporary state aid framework adopted in late March 2022 should allow all energy intensive industries to have access to state aid covering 70 - 80% of eligible costs. It has also encouraged the wider use of alternative fuels, although it doesn’t link the reason why beyond reducing imports of fossil fuels. Lastly, it bangs the drum for its recent preoccupation, the EU Carbon Border Adjustment Mechanism, this time adding electro-intensity as a main criterion for eligibility for compensation under EU emission trading scheme (ETS) indirect state aid guidelines.

Government support packages for the energy crisis are starting to be announced in European countries but the question for everyone is whether they and other actions will be enough. One problem for the cement industry will be simply staying on the radar of policy makers facing a crisis looming over their citizens. Yet if there is not enough energy to go around then rationing of some kind will be inevitable and heavy industrial users will be the first obvious targets to be told to cut back. Some months later building material supply shortages will hit. One national cement sector to watch in the coming months may be the Spanish one as it has long warned of the risks of high electricity prices.

UK: The Mineral Products Association (MPA) says it is disappointed that UK-based cement and lime producers have been excluded from the government’s compensation scheme for climate change costs. The association says that the government has, “missed an opportunity to support two essential industries during the current energy crisis, despite other industry sectors - which directly compete with cement and lime - receiving the compensation.”

Under the Department for Business, Energy & Industrial Strategy (BEIS) scheme, some energy intensive industries can apply for compensation from the indirect costs of the UK Emissions Trading Scheme (UK ETS) and Carbon Price Support (CPS) if they meet certain criteria. In the government’s 2021 consultation on the compensation mechanism, energy intensive industries needed to meet at least one of three tests to qualify. However, the MPA says that BEIS later changed this so that they had to pass all three tests and modified the targets.

Diana Casey, Director for Energy and Climate Change at the MPA, said “It is extremely disappointing that having met the criteria set out in the consultation, BEIS has decided to move the goalposts and exclude cement and lime from the scheme. UK manufacturers of all products face higher electricity and gas costs than European competitors, and this decision misses an opportunity to support the competitiveness of the UK cement and lime sectors, both essential foundation industries, especially during the current energy crisis and rapidly rising costs. Reaching net zero and delivering our economic potential requires huge investment from global businesses and it becomes harder to make the case for the UK as a location for such investment if policy costs make operating in the UK uncompetitive.”

From the Nordics to the Mediterranean, European countries lead the field in reduced-clinker cement production using supplementary cementitious materials (SCMs). While consumers, faced with ever-greater choice, continue to opt for sustainability, projects to improve existing SCMs and develop new ones have won government backing and have become a matter of serious investment for other heavy industries beside cement. European cement producers’ decisions are steering the course to a world beyond CEM I. Yet, even in Europe, great untapped potential remains.

Companies generated a good deal of marketing buzz around their latest reduced-CO₂ cement ranges in 2021 and the first quarter of 2022: Buzzi Unicem’s CGreen in Germany and Italy, Holcim’s EcoPlanet in six markets from Romania to Spain, Cementir Holding’s Futurecem in Denmark and Benelux, and Cemex’s Vertua in Spain and several other countries. All boast reduced clinker factors through the use of alternative raw materials. This, however, is really a rebranding of a long-established norm in Europe.

Since 2010, cements other than CEM I have constituted over 75% of average annual cement deliveries across Cembureau member countries (all cement-producing EU member states, plus Norway, Serbia, Switzerland, Turkey, the UK and Ukraine). This statistic breaks down differently from country to country. CEM II is the norm in Austria, Finland, Portugal and Switzerland, with deliveries in the region of 90%. Portland limestone cement (PLC) makes up a majority of deliveries in all four. It has been central to Switzerland’s transition to 89% (3.72Mt) of CEM II deliveries out of a total 4.18Mt of cement despatched in 2021. There, the main types of cement were CEM II/B-M (T-LL) Portland composite cement, with 1.38Mt (33%), and two different classifications of PLC: CEM II/A-LL PLC, with 1.28Mt (31%), and CEM II/B-LL PLC, with 888,000t (21%).

A second approach is that of the Netherlands, where CEM III blast furnace slag cement with a clinker factor below 65% predominates, favoured for its sulphate resistance and the protection it offers against chloride-initiated corrosion of steel reinforcement in marine settings. By contrast, the UK has traditionally maintained a higher reliance on CEM I cement. This can be partly explained by the preference of builders there for adding fly ash or ground granulated blast furnace slag (GGBFS) at the mixing stage. Nonetheless, CEM II Portland fly ash cement held a 14% (1.43Mt) market share in the UK’s 10.2Mt of cement consumption in 2021.

The UK Mineral Products Association (MPA) has identified limestone as an underutilised resource in the country’s cement production. Together with HeidelbergCement subsidiary Hanson Cement, it has applied for a change to National Application standards to allow the production of Portland composite cement from fly ash and limestone or GGBFS and limestone. The association has forecast that Portland composite cement could easily rise to 30 – 40% of UK cement consumption, and that this has the potential to eliminate 8% of the sector’s 7.8Mt/yr-worth of CO₂ emissions.

Metallurgical waste streams have long flowed into European cement production, primarily as GGBFS, but also as bauxite residue. In 2021, alumina production in the EU alone generated 7Mt of bauxite residue, of which the bloc recycled just 100,000t (1.4%) that year. Two projects – the Holcim Innovation Center-led ReActiv project and Titan Cement and others’ REDMUD project – aim to produce new alternative cementitious materials from bauxite residue.

By collaborating with other industries, cement producers’ investments can most effectively reduce the overall cost of using these materials in cement production. In Germany, HeidelbergCement and ThyssenKrupp’s Save CO₂ project aims to develop new improved latent hydraulic binders or alternative pozzolan from GGBFS by producing slag from directly reduced iron (DRI). The Save CO₂ team believes that GGBFS substitution for clinker has the capacity to eliminite 200Mt/yr of CO₂ emissions from global cement production.

Meanwhile in the world of mining, ThyssenKrupp and others’ NEMO project is investigating the recovery of a useable mineral fraction for cement production from the extractive waste of the Luikonlahti and Sotkamo mines in Finland and the Tara mine in Ireland, through bioleaching and cleaned mineral residue upcycling. This may give cement producers full access to Europe’s 28Bnt stockpiles of sulphidic mining waste, of which mines generate an additional 600Mt each year.

Denmark-based CemGreen, which produces the calcined clay supplementary cementitious material CemShale, is developing a shale granule heat-treating technology called CemTower. This consists of three pieces of equipment vertically integrated into cement plants’ preheaters, kilns and coolers, and brings the processing of waste materials – here oil shale – to the cement plant.

Lastly, cement producers are exploring the possible uses of waste made of cement itself. In Wallonia, HeidelbergCement subsidiary CBR’s CosmoCem project is investigating the production of alternative cement additives from large available flows of local demolition, soil remediation and industrial waste. Similarly, the Greece-based C2inCO₂ project seeks to mineralise fines from concrete recycling for HeidelbergCement to use in the production of novel cements in its Greek operations.

In Switzerland, ZND Portland composite cement (produced using fine mixed granulate from building demolitions) is the third largest cement type, with 178,000t (4.3%) of total deliveries – narrowly behind CEM I with 239,000t (5.7%).Holcim Schweiz developed its Susteno 4 ZND Portland composite cement with Switzerland’s lack of any ash or slag supply in mind, demonstrating the potential flexibility of a circular economic approach to cement production.

On 21 March 2022, the University of Trier reported that it is in the process of mapping mineral resources, waste deposits and usable residues ‘on a cross-border scale,’ in an effort to produce new materials for use in cement production. Industry participants include France-based Vicat, CBR, Buzzi Unicem subsidiary Cimalux and CRH subsidiary Eqiom. Vicat is preparing a kiln at its 1Mt/yr Xeuilley cement plant in Meurthe-et-Moselle to use in testing new alternative raw materials developed under the project.

For Cembureau and its members, work continues, with the goal of Net Zero by 2050 constantly in sight. This goal includes a reduction in members’ clinker-to-cement ratios to well below 65%. In this, the association and its members are working towards a world not just beyond CEM I, but beyond CEM II, too. What exactly this will mean remains to be seen.
