Andrew Minson from the Global Cement and Concrete Association (GCCA) kicked off this week’s Virtual Global Concrete Conference with an overview of concrete’s role in the association’s 2050 climate ambition. The association announced in September 2020 that it was starting work on this roadmap for publication in the second half of 2021, just in time for the 2021 United Nations Climate Change Conference, currently schedule to take place in Glasgow, Scotland in November 2021. Minson ran through the topic, providing an overview of concrete’s intrinsic sustainable features and the policy levers the association is considering for its forthcoming roadmap.

One point from circular economy aspects of the plan included design for dis-assembly (DfD) and long life, loose fit modes of thinking around how a building using concrete should be conceived, designed, built, used and - crucially – reused. Long life, loose fit, low energy (to use its original name) was promoted by the Welsh architect Alex Gordon from the early 1970s. It covered themes of sustainability, flexibility and energy efficiency for building design ahead of both the 1970s oil crisis and the current climate one. DfD emerged in the 1990s as a way of thinking about a building’s demolition at the start and working from there. Deconstruction or demolition is prepared for through planning and design. It allows components and materials to be removed more easily, facilitating their subsequent reuse. So, components and materials can be removed more easily allowing their subsequent reuse and elements such as columns, walls, beams, and slabs can be disassembled to facilitate this. Last year Global Cement Weekly explored a similar path with the ideas of Dutch architect and commentator Thomas Rau (GCW348) and his concept of building materials as a service, following on from the Building Information Modelling (BIM) system, and the suggestion that companies simply rent (!) building materials from their manufacturers to encourage whole life thinking.

Just how much concrete the world uses each year is a question beyond the scope of this article, given its range of applications and diversity of users. For example, the Cement Sustainability Initiative (CSI) estimated 25Bnt in 2009. Later, the International Organization for Standardization (ISO) technical committee for concrete, reinforced concrete and pre-stressed concrete placed the figure at around 33Bnt in 2016. It is worth considering how and where concrete is actually used. The chart above from the European Ready Mixed Concrete Organisation (ERMCO) shows how its members used concrete in 2018. Note that use in buildings comprised the biggest share, nearly two thirds, but that the rest included infrastructure, pavements, roads and more. Lifecycle thinking and its various offshoots can apply to all of these applications. Yet it’s easier to imagine a concrete building shell being reused within its lifespan than, say, a bridge or a road. Concrete used in infrastructure seems more suitable for re-use further down the waste hierarchy, such as recycling as an aggregate.

A few final thoughts to consider are that both Cemex and gypsum wallboard manufacturer Etex have invested in modular and/or offsite construction companies in January 2021. Both targets were relatively small companies suggesting growing interest in these sectors by larger players. Offsite building construction suits lifecycle thinking well because the modular components start off being built elsewhere before installation. Factoring in what happens afterwards should be relatively easy and expandable at scale. Finally, LafargeHolcim announced this week that it is acquiring two ready-mix concrete and aggregate suppliers in France and Italy that will give it 35 concrete plants in the region.

Sustainability places lifecycle thinking into mainstream building practice and some methods and tools will inevitably make it into any policy framework the GCCA will recommend. Whether some or all of the ideas above hang around remains to be seen but lifecycle thinking in some form or another is here already and not going anywhere.

Cement imports were one of the themes in this week’s news, with stories on the topic from South Africa and Ukraine. The former concerned the latest chapter in that industry’s saga on slowing down imports. The International Trade Administration Commission (ITAC) has started a review on tariffs imposed on cement from Pakistan that were introduced in 2015.

Local producers in South Africa have experienced mixed fortunes since 2015, such as PPC and AfriSam’s failed merger attempt or the introduction of a local carbon tax, and were starting to complain again about imports even before the effects of coronavirus in 2020. This led the Concrete Institute to lobby ITAC in 2019 about rising imports from other nations, principally Vietnam and China.

Back in 2013 cement imports from Pakistan to South Africa were 1.1Mt. This represented the vast majority of all imports to the country. Tariffs of 14 – 77% were imposed on Pakistan-based exporters in mid-2015, initially for six months, but this was then extended. Roughly a year later in mid-to-late 2016, Sephaku Holdings said that imports of cement had ‘significantly’ declined on a year-on-year basis, particularly from Pakistan. By the end of June 2016 approximately 0.16Mt had been imported compared to 0.5Mt in the previous period. However, it noted that 75% of the volume was from China. Since then imports started to creep up. Cement imports reportedly rose by 84% year-on-year in 2018 and then by 11% in 2019. Data from construction industry data company Industry Insight suggests that Vietnam accounted for 70% or 0.47Mt of the 0.68Mt of cement imported into South Africa in the first nine months of 2020. The remaining 30% or 0.20Mt came from Pakistan. In this kind of environment it seems unlikely that ITAC will do anything other than extend tariffs.

Meanwhile in the northern hemisphere, in Ukraine this week a court in Kiev dismissed a challenge by the Belarusian Cement Company to remove cement import tariffs from Russia, Belarus and Moldova that were introduced in mid-2019 for five years. Notably, a law firm representing Dyckerhoff Cement Ukraine, HeidelbergCement Ukraine, Ivano-Frankivsk Ukraine and CRH subsidiary Podilsky Cement commented favourably upon the court’s decision to uphold tariffs. These producers form UKRCEMENT, the association of cement producers of Ukraine. However, the association doesn’t include Russia-based Eurocement, which operates Ukraine’s largest cement plant at Balakleya. Relations have been poor between Russia and Ukraine since a war between the countries that started in 2014. So any trade tariffs implemented upon Russia and/or Commonwealth of Independent States (CIS) members will inevitably carry the whiff of geopolitics. Yet, in Ukraine’s defence, it also started an anti-dumping investigation into cement imports from Turkey in September 2020. Nationalism may be relevant but let’s not discount hard-nosed economics just yet.

Turkey’s involvement in Ukraine leads to last week’s presentation at Global Cement Live by Sylvie Doutres, DSG Consultants on cement and clinker trade in and out of the Mediterranean region. Readers can watch the presentation here but the headline story here was the trend of reducing exports away from southern European countries such as Spain, Italy and Greece, to greater exports from North African countries and Turkey over the last decade. Turkey particularly has pushed its share of exports even more in 2020 despite (or perhaps because of) a tough domestic market. The general trend here away from southern Europe has been blamed on European Union-based (EU) producers becoming less competitive often against newer plants in nearby countries.

Battles between producers and government tariff policies are a perennial feature of any market in commodities such as cement. The ebb and flow of import and export markets cover many factors including production costs, distribution networks, tariff structures and more. Distinctive features of cement trading, for example, are the high cost of transporting heavy building materials over land and the world’s chronic cement production overcapacity. In the EU’s case one reason that often gets blamed is the emissions trading system (EU ETS) and the mounting cost it is imposing upon cement production. For example, today’s story that Holcim España wants to convert its integrated Jerez plant into a grinding unit has been blamed on falling exports and a reduction in ETS credits. It is noteworthy then that the EU ETS rate breached the Euro30/t level in December 2020. This may be good news for the sustainability lobby but the exodus of exports away from Southern Europe tells its own story. What form the EU ETS carbon border adjustment mechanism takes as part of the EU Green Deal will be watched closely by producers both inside and outside the EU.

Global Cement Live continues on 21 January 2021 with Kevin Rudd, Independent Cement Consultants, presenting 'Independent or third party factory acceptance testing of major cement plant equipment and critical spare parts and the challenges of Covid’

There have been two developments from ThyssenKrupp’s ongoing restructuring worth noting by the cement sector in recent weeks. The first is that the Germany-based engineering and steel producer has stopped trying to sell its cement plant division. The second is that Denmark-based FLSmidth is holding serious talks about buying its mining division.

ThyssenKrupp first announced plans for a major restructuring in mid-2019 with an anticipated reduction of 6000 jobs across the business. The sale of its elevator business for Euro17.2bn to private equity was announced in February 2020. Later in May 2020 it then revealed plans to divide its previous business areas into core, dual and multi track segments. Core - including Materials Services, Industrial Components (Forged Technologies and Bearings) and Automotive Technology – would be kept as before. Dual-track – including Steel and Marine – would either be kept as before or considered for consolidation. Multi-track - including cement plant engineering, mining and more – would be sold, added to a partnership or closed. By size, core reported sales of Euro16.1bn (53%) in the company’s 2019 - 2020 financial year, dual-track reported Euro8.8bn (29%) and multi-track reported Euro5.5bn (18%).

Volkmar Dinstuhl, formerly in charge of mergers and acquisitions, was put in charge of Multi-track. By October 2020 he was publicly admitting that the division was planning to “find a solution for all our businesses within the next two years” including cement plant engineering. In the same interview he described the Multi-track division as an internal private equity fund. However, the elevator business sale has been seen by several commentators as giving ThyssenKrupp more freedom around how to conduct its restructuring. Three months later and Handelsblatt, a German business newspaper, reported this week that ThyssenKrupp’s cement plant division may have avoided its multi-track fate. It cited internal communication to employees about what’s been happening with the sale. Principally, orders have picked up in the company’s new financial year, since October 2020, and although a sale has not been ruled out, it won’t be pursued until late 2021 at the earliest. This is potentially good news for the sector as a sign that the market may be improving and definitely good news for those employees working for the division.

As a competitor, FLSmidth would have been expected to be potentially interested in buying either ThyssenKrupp’s mining or cement plant division, or both. So, the only question was, when it made a point of saying publicly that it was in non-binding negotiations to buy mining, what about cement?

Looking at the numbers shows that FLSmidth’s mining division did better than its cement one in the first nine months of 2020 with order take up year-on-year and the mining industry described as being relatively resilient during the coronavirus crisis, with the majority of mines operational across regions. By contrast it pointed out that the cement market was still ‘severely’ impacted by the coronavirus pandemic and that future cement demand was dependent on general economic growth. Acquisition activity in mining certainly seems like the safer bet at the moment. Yet the temptation to neutralise a competitor may have been a strong one. With the mining deal still in progress and the cement sale possibly ended for now, we’ll just have to wait and see. Other buyers for both divisions are no doubt waiting in the wings should circumstances allow.

One final fun fact to consider is that the man put in charge of selling both of ThyssenKrupp’s mining and cement plant divisions, Volkmar Dinstuhl, just happens to be a World Chess Federation (FIDE) recognised International Master. Being good at chess doesn’t automatically confer skill at anything else. Just look at former world champion Gary Kasparov’s political ambitions in Russia for example. Yet, ThyssenKrupp’s elevator division sale has been seen as one of the largest leveraged European buyouts in recent years and has appeared to have bought it some time to mull its options over its cement plant division. With this in mind, any potential buyers for the rest of Multi-track may be wondering just how many moves ahead this seller is thinking.

LafargeHolcim took what appeared to be a surprising decision this week when it announced it was buying roofing and building envelope producer Firestone Building Products (FSBP). The deal raises eyebrows because it seems to be a departure from the building material producer’s previous dedication to its three major pillars: cement, aggregates and ready-mixed concrete. Yet, it follows the logic of sticking to safer markets both geographically and in terms of sustainability.

First some background. Originally, Global Cement was following the auction for FSBP via its sister publication Global Insulation. Reporting from Bloomberg in December 2020 focused on more obvious bidders such as Ireland-based insulation producer Kingspan and roofing products producer Standard Industries. However, Kingspan has been struggling publicly with fallout from the Grenfell Tower fire inquiry in the UK. Despite not formally supplying any of its products for the tower block in London, it has become embroiled in the allegations of a general culture of cheating safety tests for foam board-based insulation products. At the almost the same time that it dropped out of the FSBP bidding, its chief executive officer (CEO) Gene Murtagh apologised for ‘process shortcomings’ that had been highlighted by the ongoing inquiry. Make of this what you will. No word on why Standard Industries left proceedings but it also seems to part of a consortium trying to take over US-based chemical producer WR Grace. All of this is relevant because, from publicly-available sources, LafargeHolcim appeared to emerge out of nowhere to snaffle up FSBP. However, it seems ludicrous that a company with a revenue of around Euro25bn in 2019 could simply pull something like Euro2.8bn out of its pocket at the last minute. It’s likely it was quietly in the bidding process the whole time.

Back in the early 2010s Lafarge was busy selling off its major ‘non-core’ assets like its gypsum business in the wake of picking up debts from acquisitions like cement-producer Orascom in the Middle East. This then turned into a string of divestments following the merger with Holcim to try and shore up the business along with a general pivot towards concrete as the key end-product as sustainability concerns gathered pace. Producing cement remains a major part of LafargeHolcim’s business but a focus on the whole lifecycle of concrete is vital as a hedge against the high process emissions associated with making clinker. Cement factories run the risk of becoming so-called stranded assets depending on future government regulations.

In its acquisition statement LafargeHolcim played up the sustainability credentials of buying FSBP. It noted that up to 60% of buildings’ energy is lost through roofs and that FSBP’s products help to reduce this. Then it made the link that FSBP’s technologies and products complement LafargeHolcim’s sustainable building solutions like its ECOPact green concrete and its EcoLabel sustainable product range. Later, when LafargeHolcim CEO Jan Jenisch spoke to US broadcaster CNBC he described the move as a ‘perfect fit’ for his company’s goal, “to be the most sustainable and most innovative building materials supplier in the future.” The geographical point of the acquisition hasn’t been dwelt on as much as sustainability but no doubt buying a business based in the US with revenue of US$1.8bn is seen as being far safer than buying, say, a similar concern in East Asia.

Investing in a business that sells products that reduce energy loss in the building envelope follows the trend of the moving sustainability-related risk along the supply chain from cement to concrete and beyond. Ultimately consumers will have to pick up the true carbon price of their buildings, but if building materials producers buy more of the envelope they can spread this cost more thinly and hopefully build up the market in the process. One can also imagine it fitting with the mindset of CEO Jan Jenisch, the former boss of Sika, a company that sells speciality chemicals across a wide range of markets. The real test here is whether LafargeHolcim will buy more companies in the wider building materials sector or if other heavy building materials producers will copy them. If so then the days of heavy building material producers sticking to the three pillars of cement, aggregates and concrete may be numbered.
