Analysis

In case you missed it, last week we covered a news story about Taiheiyo Cement’s plans to step up its lithium-ion battery recycling business at its integrated Tsuruga plant. It’s the latest step in the Japan-based cement producer’s collaboration with recycling company Matsuda Sangyo. The work is timely given that electric cars accounted for 2.6% of global car sales in 2019 and this share is growing. Many of these electric vehicles use lithium-ion batteries and moving away from fossil fuel powered transport creates new problems such as how to manage old batteries that can no longer be used.

Taiheiyo Cement and Matsuda Sangyo have been working on their process since 2011. First, they dismantle the batteries to extract base metals and plastics. They then heat the batteries in a dedicated ‘roaster’ using waste heat from the cement production process, before crushing and sorting them to remove cobalt, lithium, aluminium and scrap iron. Hydrogen fluoride produced in this stage is sent to the kiln where it is detoxified by calcium. Remaining elements from the battery that are not reclaimed are then used as an alternative fuel by the cement plant.

Taiheiyo Cement says that its roasting equipment can process up to 10t/day but it’s difficult at this stage to assess what demand for this service they might encounter. If, one estimate of 2m/yr used lithium-ion batteries by 2030 is correct and Taiheiyo Cement’s processing rate doesn’t get much higher, then 500 cement plants could possibly solve this problem. Yet, Taiheiyo Cement and Matsuda Sangyo have made no mention of the economics of their process. Other recycling methods also exist and research into new ones is ongoing. Cement plants recycling batteries might be economic compared to these alternatives or it might not, only time will tell.

The wider point here is that here is yet another industrial and logistical process that can potentially be linked to cement production. It follows well known ones, such as using alternatives fuels or captive power plants, or more novel ones, such as CO₂ or hydrogen networks. In each case the business of making cement changes as new methods are learned, new commodities are sought and new markets are connected. The cement company then has a choice about how involved it wants to become with each new process. The classic example here is the waste processing companies that surround co-processing, with some cement companies having their own dedicated subsidiaries, for example LafargeHolcim and Geocycle.

As it all becomes more complicated the role of a cement plant slowly becomes redefined. If a cement plant disposes of municipal waste and car batteries for its local community, generates electricity from its solar or wind plant for a nearby city and uses its CO₂ to either produce biofuels, plastics or baking soda is it still just a cement plant? The pivot by building materials manufacturers in recent years from a focus on cement to concrete suggests that once the societal or economic conditions are right it could change. For the time being cement plants remain cement plants but give it a thought next time you buy a new car.

There has been good news from the German Cement Works Association (VDZ) this week. Following a strong start to the year, the association expects cement consumption in 2020 to remain similar to the level, 28.7Mt, reported in 2019. VDZ president Christian Knell acknowledged the difficulty in making forecasts, this year of all years, but said that the association remained positive since demand had held up so well. He noted the continued operation of construction sites, despite the local coronavirus-related lockdown from March 2020, and the ‘quick action’ of politicians.

The year certainly started well, with a 33% year-on-year increase in domestic cement deliveries to 1.43Mt in January 2020 from 1.07Mt in January 2019. This was due in part to good weather, although it also looks good because 2019 started badly compared to 2018. Yet, the VDZ’s assessment has been supported by the results of the main producers operating in the country. HeidelbergCement reported that Germany bucked the trend of its Western and Southern Europe Group area in the first half of 2020 with a ‘positive market development’ whereas deliveries declined significantly everywhere else. Similarly, LafargeHolcim noted a ‘resilient’ performance in Germany. Buzzi Unicem released a more detailed assessment, with shipments of hydraulic binders down in April and May 2020 but then back up with a recovery in June 2020. Overall its cement plants reported a slight decline in sales for the first half of the year. Concrete production grew however, by 6% year-on-year, possibly aided by the plants that the group purchased in 2019.

Germany’s success appears to be down to two factors. The first, as Knell mentioned above, is that it was able to keep much of its construction industry open through its lockdown. Dieter Babiel, the head of Hauptverband der Deutschen Bauindustrie – the main German construction industry association - reckoned that the industry was operating at about 80% capacity in May 2020 compared to the situation in other large European countries like France, the UK, Spain and Italy where building sites totally closed at the height of local lockdowns before gradual reopening. Bauindustrie has since reported falling monthly order intake as coronavirus-effects on the general economy filter through to construction. The other reason is that the country has managed to control its outbreak better compared to other European countries. It has reported the third most cases in Europe but its fatality rate is only 4% compared to 14% in the UK, Italy and France. This has been attributed to strong public health measures and high levels of testing, particularly with respect to elderly residential care.

It’s not all plain sailing though since the International Monetary Fund (IMF) has projected a 7.8% decline in Germany’s gross domestic product (GDP) in 2020. Likewise, the VDZ is predicting weakening construction markets and cement demand in the fourth quarter of 2020. It cited falling orders and requests for building permits as mounting evidence for this trend. From here a gloomier outlook is foreseen for 2021 as construction budgets for commercial and government projects are cut. At the same time uncertainty in the labour market is expected to drag down the residential market. With this in mind the VDZ is predicting cement demand to drop by 3 – 5% in 2021.

To end on an upbeat note, if the VDZ’s forecasts are accurate, then the German cement sector looks like it might weather the coronavirus-downturn better than other industries. It knows a downturn in construction is coming and it can prepare for it.

Building materials manufacturer Saint-Gobain summed up the situation large companies face due to coronavirus in its second quarter results when it said that it faced, “very different situations from one country and market to the next.” Financial results are in from many of the largest multinational cement producers outside of China and the basic picture is as Saint-Gobain describes.

Sales revenue for LafargeHolcim, HeidelbergCement and Cemex are all down by around 10% year-on-year for the first half of the year. The variation between different geographical regions is large with some reporting sales declines of up to 20% and others noting rising sales, with one above 5%. Generally, recoveries were reported in June 2020 or when governments relaxed their lockdowns. There’s more variation with earnings figures although this may be down partly to the different figures each company likes to use. Around this is plenty of talk about liquidity and cost cutting programmes to sooth investors.

Where it starts to become more interesting is when the companies talk about what they think will happen next. As Robert McCaffrey picked up upon in last week’s Global Cement Live there was a divergence between LafargeHolcim’s optimism for the second half of the year and HeidelbergCement’s caution. LafargeHolcim said it expected a, “Fast demand recovery with an encouraging outlook for the second half of 2020.” Instead, HeidelbergCement said, “A further wave of infections may occur at any time, which would have an impact on construction projects already started or announced in the individual countries. Against this backdrop, it is still not possible to estimate the full effect of the corona crisis on the company results for 2020.” Cemex sat on the fence with, “We expect that Covid-19 will continue to challenge our operations in new ways over the next few quarters.” Contrast this with Buzzi Unicem’s prediction, “Visibility for the second half of the year continues to be very limited and our forecasts are based on a scenario of gradual mitigation of the infections and related restrictions on economic activity.”

This difference in outlook may be subjective. Both LafargeHolcim and HeidelbergCement only had one geographical region each that reported growing sales in the first half of 2020 but LafargeHolcim’s ‘positive’ region represented a larger share of the group’s revenue. Alternatively, it may just be that the companies have different characters and this is reflected in their forecasts. Humans can be either be pessimistic or optimistic and so too can companies.

Of the large regional players, most of the Chinese cement producers are yet to release results for the second quarter of 2020 so there is little to say. Data out this week from China’s Ministry of Industry and Information Technology shows that cement output fell by 4.8% year-on-year to 1Bnt in the first half of 2020. UltraTech Cement, India’s largest producer, saw its revenue fall by 22.5% year-on-year to US$2.34bn for the first half of 2020. The worst of this was in the first quarter of the Indian financial year to 30 June 2020 with revenue falling by 33% with consolidated sales volumes down by 22% year-on-year to 14.7Mt. This coincided with the country’s ‘total’ lockdown period from late-March 2020 to 1 May 2020. Dangote Cement, a large African producer, reported growth in both sales and earnings with full or partial lockdown implemented in South Africa, Congo and Ghana in April 2020 before reopening in May 2020.

This is just a snapshot of what’s been happening with mid-year results awaited from the likes of CRH, Votorantim and, as mentioned above, the Chinese producers. Blanket lockdowns clearly damage construction markets, so future government strategies in tackling the ongoing wave of the pandemic or future waves will have consequences for the financial performance of construction material companies. In the meantime, in Europe at least at the moment, targeted regional lockdowns seem to be the public health measure of choice when outbreaks get out of control. How this translates to balance sheets will be revealed later in the year. In the meantime, while the world works out how to cope with coronavirus, expect more uncertainty.

Consolidation of the Chinese cement industry looks set to take a major step forward this week. China National Building Material Company (CNBM) announced that it is restructuring its cement production assets and companies under one subsidiary, Tianshan Cement. The move is significant since CNBM is the world’s largest cement producer, with a production capacity of over 500Mt/yr. That’s more than the total output of any single country except China. It’s also between a quarter and a third of national capacity domestically.

Little information has been revealed except that it concerns most of CNBM’s cement producing subsidiaries. Namely: China United Cement, South Cement, North Cement, Southwest Cement and Sinoma Cement. Note that this leaves out Ningxia Building Materials and Qilianshan Holdings, although some commentators have suggested that they may be merged in later on. It was announced to stock markets as a proposal with a ‘letter of intent of cooperation’ exchanged between CNBM and Tianshan Cement. CNBM will remain the controlling shareholder of Tianshan Cement after the restructuring. However, the assets concerned - the cement companies are still being discussed and considered. The aim of the reorganisation is to ‘facilitate resolving industry competition’ among the subsidiaries of CNBM.

The move is expected to significantly increase operational efficiency at the cement companies as they start to act in a more coordinated manner. It also fits the government-requested drive for the industry as a whole to consolidate and follow supply-side reform initiatives by, hopefully, eliminating old production assets and other measures. Indeed as CNBM’s president Peng Shou said in the company’s report for 2019, “Production overcapacity of the industry has not been fundamentally resolved. The task of cutting production overcapacity was arduous, and the supply-side structural reform remains the major task.” The company says it is committed to building a three-pillar development platform of cement, new materials and engineering services.

How much more operational efficiency the world’s largest cement producer will need to do this is a key question. In 2019 the sales revenue from its cement business rose by 12% year-on-year to US$18.7bn and its earnings before interest, taxation, depreciation and amortisation (EBITDA) increased by 19% to US$5bn. Growth at this level is novel to western-based multinational cement producers! So the implication might be that CNBM is hoping to turbo-charge its financial performance before (or if) the serious government-forced supply side cuts occur or a general economic slowdown happens so that it can return to ‘normal’ Chinese performance afterwards.

The Chinese Cement Association presented a good overview of the history of CNBM that you can read here. The quick version is that it’s the embodiment of the Chinese government’s desire to build and merge its cement industry since 2005. The latest restructuring with Tianshan Cement is the latest chapter in this 15 year story. What the reorganisation means internationally is ‘probably not much’ in the short term. Better coordination between CNBM’s cement companies could have implications in the longer term if they acted together on an international strategy, such as a strategy on exports for example, or if group-wide suppliers were agreed upon.

That’s all on China but finally if readers were not able to join us for Global Cement Live last week on 23 July 2020, we recommend watching the playback of Arif Bashir, Director (Technical/Operations) of DG Khan Cement Nishat Group Pakistan. He gave a great overview of Pakistan’s cement industry and the challenges it is facing and overcoming. Be sure to tune in for this week’s guest speaker, Regina Krammer from Loesche who will be discussing how the coronavirus crisis will change communications in the sector.

Rwanda’s newest cement grinding plant is set to start commissioning at a great time. Last week Milbridge Group subsidiary Prime Cement said that its 0.6Mt/yr grinding plant in Musanze, Northern Province was preparing to start up in August 2020. This week the main local producer, Cimerwa, announced that it was setting standardised cement prices in an attempt to control speculation in the market following a shortage. According to local press, spikes in prices have been caused by an urgent supply tender from the Ministry of Education, which has started a large-scale project to build over 20,000 classrooms. Prime Cement is unlikely to make a difference to this particular shortage but its timing is spot on.

Cement price surges in land-locked African countries crying out for construction materials are not new but it’s always illuminating to review how the situation is changing. Rwanda’s sole 0.6Mt/yr integrated plant is run by Cimerwa, a subsidiary of South Africa-based PPC, near Bugarama in the south-west of the country, close to the borders with Democratic Republic of the Congo (DRC) and Burundi. The new grinding plant is located in the north-west near the borders with DRC and Uganda. It will join another grinding plant run by Kenya’s ARM Cement at Kigali.

PPC’s operation in Rwanda has performed well in comparison to a poor market back home in South Africa. For its financial half year to September 2019 Cimerwa reported revenue growth of 28% year-on-year to US$31.2m due to a 20% increase in sales volumes. Earnings rose even more in percentage terms due to higher volumes and an improved cost per tonne performance, likely due to a debottlenecking project. More recently, PPC said that its operations in Rwanda were disrupted in April 2020 due to a coronavirus lockdown that started in late March 2020. It partially resumed operations in the second half of April 2020 with cement sales volumes for the month expected to be 15 - 20% of those in April 2019. The other point of note is that the Rwandan government was trying to sell its minority share in Cimerwa in mid-2019 but nothing has been publicly announced since then. However, Cimerwa was reported as being in the process of listing on the Rwanda Stock Exchange in May 2020.

Rwanda’s other grinding plant at Kigali has had problems with its parent company in Kenya. ARM Cement went into administration in mid-2018 and its assets have gradually been sold off since then amidst legal wrangling. It has also had ongoing operational issues with interrupted production due to clinker and coal shortages caused by import issues with Tanzania. An attempt to sell the 0.1Mt/yr grinding plant in September 2018 failed when an auction didn’t even reach one tenth of the estimated market value of US$1.4m. The plant was still reportedly on sale in May 2020.

The new Prime Cement grinding plant will have a production capacity of 0.6Mt/yr. It has been supplied by Germany-based Loesche, who installed a Loesche Jumbo CCG (Compact Cement Grinding plant) with mill type LM 30.2. The project has been reported to have a cost of around US$65m. A second phase was also mentioned at the time of the initial announcement that might include upgrading the grinding plant to a fully-integrated one at a later stage. Time will tell. In the meantime though it will be interesting to see whether the new plant has the same raw material issues that ARM’s Kigali Cement has had. One potential source of clinker is the integrated Hima Cement at Kasese in Uganda. Bamburi Cement reported in May 2020 that its Hima Cement subsidiary in Uganda was unable to ‘access’ the market in Rwanda in 2019 due to ongoing trade problems across the Rwanda-Uganda border.

Rwanda’s cement consumption has been reported to be 0.7Mt/yr so a new combined national production capacity of 1.4Mt/yr seems likely to create significant exports. Other countries in the region have also noticed what’s going on in Rwanda and want to do likewise. In June 2020 DRC’s Industry Minister Julien Paluku talked up plans of reviving the 0.3Mt/yr state-owned National Cement Plant (CINAT) in Kimpese. He noted that DRC has been partly reliant on cement produced by Cimerwa in Rwanda, which has been serving a combined demand of 900,000t/yr in DRC and Burundi.

A statistic that received a fresh airing this week was one from the World Bank in 2016 that worked out that the price of cement in Africa was on average 183% higher than the global average. It popped up in a news article about the expanding Nigerian cement industry but it applies to the whole continent. While it continues to hold true, exports will boom and plants will keep being built in the places that exports can’t reach.
