Analysis

In case you’ve missed it there’s been a boom in cement demand in China during the current quarter. Henan province saw a run on cement prices in November 2019 that the local press described as ‘crazy.’ Some companies were issuing price adjustments twice a day, according to the China Cement Association. The article on the CCA’s website also includes a video showing dozens of cement trucks queuing at a mill with the caption ‘all the plants are like this, don’t ask the price any more.’

The CCA’s blamed the situation in Henan on pollution controls on production and a rebound in cement demand. Weather-based pollution controls enacted in late October 2019 shut-down or limited production at 66 of the province’s 72 clinker production lines. Builders were then forced to source cement from neighbouring Shanxi, Hebei and Shaanxi provinces. At the same time demand for cement from real estate and infrastructure sectors picked up in the fourth quarter of 2019. Following advice from the local cement manufacturers’ association, the provincial government relaxed the rules on peak shifting that normally run from November to February in a bid to control the situation. Cement prices in Henan hit a high in mid-to-late November 2019 and have since subsided somewhat.

Nationally, Chinese cement prices hit a high in late November 2019 beating the highest level in 2018 and also setting the highest price since 2011. The key regions driving the increase have been in central and south China, including Guangxi, Guangdong and Henan. One more thing to note here is that peak shifting or seasonal shutdown of production capacity has different dates in different provinces. So, potentially, the situation could repeat itself if unexpected demand continues and provincial governments fail to monitor the situation.

Recently a couple of economic indicators in China have suggested a recovery in infrastructure spending in recent months, supporting increased cement demand. Data from Wind quoted by the Financial Times newspaper suggests that the cement price rose by 15% since September 2019 in large cities. Reinforced steel (rebar) and aggregates prices have increased similarly. At the same time the South China Post newspaper has reported a growth in the Purchasing Managers’ Index (PMI), an indicator of manufacturing activity that could also point to renewed infrastructure spending. Central government is also reported to be taking measures to support provincial infrastructure development.

If true then this may be creating some pretty direct lessons in economic interventionism. The Chinese government appears to be stimulating demand for cement via infrastructure growth while restricting production at the same time. Cement prices have reacted in a ‘crazy’ fashion. The real tension here is between two conflicting desires: protecting the economy and protecting the environment. The state planners may be grappling with this one for a while.

The National Council for Cement and Building Materials (NCB) International Seminar is running this week in New Delhi and this gives us a good opportunity to take a snapshot at the world’s second largest cement industry.

Data from the Ministry of Commerce & Industry shows comfortable cement production growth of 4.4% year-on-year to 255Mt in the first nine months of 2019. As graph 1 shows there was higher production growth in 2018 but this followed a decline in 2017, due to partly to the government’s demonetisation policy. October 2019 confirms a trend of falling year-on-year growth from August 2019 onwards following a peak growth rate in mid-2017.

Analysts like ICRA have blamed the growth slowdown on the general election in mid-2019 and then the monsoon rains. By region in the six months from April to September 2019 it noted a slowdown in demand due to slowing government projects in northern, eastern and central areas. Labour concerns were reported in the north, centre and Gujarat in the west. Raw material shortages were picked up on such as water in Maharashtra and sand in the east and Andhra Pradesh. Positive growth was reported in Kerala, driven by post-flood reconstruction and low-cost housing schemes, and in Karnataka due to general construction activity. Broadly, UltraTech Cement, the country’s largest cement producer, in its November 2019 investor’s presentation, agreed with this assessment. It noted growth in the northern region and declines elsewhere. Like ICRA it too picked up on low cost housing declaring it to be a ‘key cement consumption driver.’

Away from the figures the main news stories have been continued consolidation such as the auction for Emami Cement and UltraTech Cement’s acquisition of Century Textiles and Industries. The sale of the former for plants in east and central regions has been linked to all the major local producers, including those owned by LafargeHolcim and HeidelbergCement. A report in the Hindu newspaper last week quoted a source placing UltraTech Cement and Nirma Group as the frontrunners with a valuation of around US$700m and an announcement at some point in December 2019. Despite UltraTech Cement’s market dominance nationally, its 17% production share in the east is low compared to its presence elsewhere. Nirma Group’s subsidiary Nuvoco Vistas is one of the smaller producers but, notably, it picked up Lafarge India’s assets in 2016.

Investment in new production capacity has continued with announcements from both JSW Cement and HeidelbergCement in recent weeks about expansion plans well into the mid-2020s. This follows planned projects from Dalmia Bharat Cement and Ramco Cement as well as orders from the JK Cement and Shree Cement. This ties into the capacity growth forecasts of around 120Mt over a similar timescale that the analysts were predicting in the middle of 2019. JM Financial, for example, pinned most of this growth on the south followed by the east and north. However, The India Cements said in November 2019 that it was delaying its expansion projects in Uttar Pradesh due to slowing government spending.

As is usual for a country with a low per capita cement consumption, on the national scale, one of the tensions in the Indian cement industry has been the balance between the capacity utilisation rate and the commissioning of new capacity. Its utilisation rate was below 60% in 2018 and a number of producers started reporting the negative effects of higher input and raw materials costs on their financial results. Knowing when to stop and start capacity growth is critical in this kind of environment. Specifically in India’s case curveballs such as government action on pollution and the country’s growing need for imports of coal as well as a burgeoning waste fuels sector are factors to keep an eye on. Finally, general trends such as UltraTech Cement’s focus on the Indian market, despite buying assets outside the country, are also compelling to watch as it chooses to concentrate on just one country. There are parallels here with other similarly-sized multinational that have also been focusing on core markets elsewhere in the globe.

Cemex pushed ahead yesterday and announced that it had sold the Kosmos Cement Company to Eagle Materials for around US$665m. It owns a 75% stake in the company, with Italy’s Buzzi Unicem owning the remaining share, giving it roughly US$449m once the deal completes. Proceeds from the sale will go towards debt reduction and general corporate purposes. The sale inventory includes a 1.7Mt/yr integrated cement plant in Louisville, Kentucky as well as seven distribution terminals and raw material reserves.

The decision to sell assets makes sense given Cemex’s financial results so far in 2019. It reported falling sales, cement volumes and earnings in the first nine months of the year although much of this was down to poor market conditions in Mexico. However, the US, along with Europe, was one of its stronger territories with rising sales. Earnings were impaired in the US, possibly due to bad weather in the southeast and competition in Florida, but infrastructure and residential development were reported to be promising.

United States Geological Survey (USGS) data also supports a picture of a growing US market. Shipments of Ordinary Portland Cement and blended cements grew by 2.4% year-on-year to 66.9Mt for the first eight months of 2019 from 65.4Mt in the same period in 2018. By region growth can be seen in the North-East, South and imports. Declines were reported in the West and Midwest. The states of Alabama, Kentucky, Tennessee – the area where the Kosmos plant is located – saw shipments grow by 4% to 4.77Mt from 4.58Mt. It is worth noting that Louisville is in the north of Kentucky near the border with Indiana, where shipments also grew.

The Portland Cement Association’s (PCA) fall forecast may also have helped Cemex’s decision. Ed Sullivan, PCA Senior Vice President and Chief Economist, said that he expected cement consumption in the US to continue growing in 2019 and 2020 but with a slowing trend into 2021 following general gross domestic product (GDP) predictions. The PCA’s view is that pent-up demand following the recession in 2008 was gone and the economy was gradually weakening. Crucially though it didn’t think a recession was impending. In this scenario Cemex might be taking a medium-term view with regards to the Kosmos Cement Company.

Another more general interesting data point from the USGS was the change in import origins to the US. Imports grew by 11.3% to 66.9Mt in January to August 2019. The top five importing countries and their overall share remained the same but there was some movement between them. Turkish and Mexican imports surged at the expensive of Chinese ones as can be seen in Graph 2. The go-to explanation for this would be the on-going US - China trade war. Cemex is a Mexican company with a strong presence in both the US and Mexico. This change in the make-up of the import market in the US may also have informed its decision to sell Kosmos Cement as it looked at the macro scale.

More generally the US market is looking buoyant in the short to medium term. Plants are being sold like Kosmos Cement to Eagle Cement and the Keystone cement plant in Bath, Pennsylvania to HeidelbergCement and a major upgrade project is underway on the new production line at the Mitchell plant in Indiana. In Cemex’s case, as ever with asset sales, the seller sometimes has to make the hard decision of whether to divest a plant in a growing region to help the business in other places that might not be doing so well. The growth of America’s largest locally owned producer, Eagle Cement, may also give cheer to the US’ current ‘America First’ administration.

Microsoft co-founder Bill Gates entered the world of cement this week with a public relations blitz for Heliogen. He’s one of the backers of a new Californian technology startup looking to use concentrated solar power (CSP) to power heavy industrial processes like clinker or steel production. The company says it has concentrated solar energy commercially to levels above 1000°C.

Its process, called HelioMax, uses a closed-loop control system to improve the accuracy of a heliostat system. It says it achieves this by using computer vision software to better align an array of mirrors to reflect sunlight towards a single target. Temperatures of up to 1500°C is one of its targets so that it can apply itself to a variety of processes in the cement, steel, mining, petrochemical and waste treatment industries. It says it can do this for US$4.5/MCF. Another target once it hits 1500°C is to start manufacturing hydrogen or synthetic gas fuels.

Heliogen’s press release was picked up by the international press, including Global Cement, but it didn’t mention the similar work that SOLPART (Solar-Heated Reactors for Industrials Production of Reactive Particulates) project is doing in France. This project, backed by European Union Horizon 2020 funding, is developing a pilot scale high temperature (950°C) 24hr/day solar process for energy intensive non-metallic minerals’ industries like cement and lime. It’s using a 50kW solar reactor to test a fluidised bed system at the PROMES (PROcédés, Materials and Solar Energy) testing site in Odeillo, France.

Heliogen’s claim that it can beat 1000°C is significant here but it doesn’t go far enough. Clinker production requires temperatures of up to around 1450°C in the sintering phase to form the clumps of clinker. SOLPART has been only testing the calcination stage of clinker production that suits the temperature range it can achieve. Unless Heliogen can use its method to beat 1450°C then it looks likely that it will, similarly, only be able to cut fossil fuel usage in the calcination stage. If either Heliogen or SOLPART manage to do even this at the industrial scale and it is cost effective then the gains would be considerable. As well as cutting CO₂ emissions from fossil fuel usage in cement production this would reduce NO_x and SO_x emissions. It would also cut the fuel bill.

As usual this comes with some caveats. Firstly, it doesn’t touch process emissions from cement production. Decomposing limestone to make calcium oxide releases CO₂ all by itself with no fuel. About one third of cement production CO₂ emissions arise from fossil fuel usage but the remaining two thirds comes from the process emissions. However, one gain from cutting the amount of fossil fuels used is a more concentrated stream of CO₂ in the flue gas. This can potentially reduce the cost of CO₂ capture and utilisation. Secondly, concentrated solar power systems are at the mercy of the weather, particularly cloud cover. To cope with this SOLPART has been testing a storage system for hot materials to allow the process to work in a 24-hour industrial production setting.

Looking more broadly, plenty of cement producers have been building and using solar power to supply electricity. Mostly, these are photovoltaic (PV) plants but HeidelbergCement built a CSP plant in Morocco. Notably, PPC Zimbabwe said this week that it was building a solar plant to supply energy to two of its cement plants. It is doing this in order to provide a more reliable source of electricity than the local grid. India’s Birla Corporation has also said that it is buying a solar energy company today. The next step here is to try and run a cement plant kiln using electricity. This is exactly what Cementa, HeidelbergCement’s subsidiary in Sweden, and Vattenfall have been exploring as part of their CemZero project. The pilot study demonstrated that it was technically possible but only competitive compared with ‘other alternatives in order to achieve radical reductions in emissions.’

None of the above presents short or medium-term reasons for the cement industry to switch to solar power in bulk but it clearly deserves more research and, critically, funding. One particular strand to pull out here about using non-fossil fuel powered clinker production systems is that it produces purer process CO₂ emissions. Mounting carbon taxes could gradually force cement plants to capture their CO₂ but once the various technologies above become sufficiently mature they could bring this about sooner and potentially at a lower cost. In the meantime the more billionaires who take an interest in cement production the better.

As most of the larger cement producers have released their financial results for the third quarter of 2019 it’s time to see how they are doing so far this year.

LafargeHolcim is looking good, with rises in both its net sales and earnings on a like-for-like basis. The sale of its assets in South-East Asia earlier in the year and in 2018 may have appeared to reduce its figures, but the like-for-like growth suggests that the strategy its working. This has been driven by markets in Europe and North America as its other big market, Asia, has continued to slide. The latter vindicates the group’s decision to partly leave the region, in the short term at least. It’s also interesting to note that at the macro-scale LafargeHolcim’s ready-mixed concrete (RMX) sales fell by 1.3% on a like-for-like basis to 7.4Mm³ in the first nine months of 2019. What does this mean for a building materials company that has been moving towards the whole supply chain and concrete?

Anhui Conch Cement reported cement and clinker sales volumes of 202Mt in the first half of 2019, a 42% year-on-year growth for the same period in 2018. Its revenue increased by 42% year-on-year to US$15.9bn in the first nine months of 2019 from US$11.1bn in the same period in 2018, putting it ahead of Germany’s HeidelbergCement in sales terms. The group was coy on how it actually managed to boost its sales so fast in a country where cement sales only rose by 5% in the first half of the year. Yet, it did admit to slowing sales growth in West China in the first half. A 5% fall in fuel and power costs no doubt helped its profit margins also. Notably, its overseas sales nearly doubled to US$143m in the first half of 2019 or 2% of its total revenue.

HeidelbergCement’s financials were solid, with growing revenue, earnings and profits. This was balanced by falling cement and clinker sales volumes. Cement sales fell in all group regions with the exception of North America. However, it was able to boast about ‘positive results in all group countries in the third quarter except for Egypt’s. Company head Bernd Scheifele summarised the sitaution by saying that, “price increases and strict cost discipline more than compensated for the slightly weaker demand for our products in the third quarter.”

Of the building materials companies with larger revenues, Cemex has had a tougher time of it so far in 2019 with declining sales, cement volumes and earnings. In part this has been due to a poor market in Mexico, although chief executive officer (CEO) Fernando A Gonzalez said that the group believed that weak demand for their products was ‘bottoming out’ and that a new infrastructure program made them hopeful looking forward. The group’s Middle East and Africa region also caused concern with a 3% drop in sales volumes in the Philippines, one of its key South-East Asian territories.

Things to note from the smaller producers featured here are as follows. India’s UltraTech Cement says it is the world’s third largest cement producer outside of China. With an installed production capacity of over 100Mt/yr in India this may well be the case. The vast majority of this is based at home in India. Alongside this, its financial figures seem buoyant as it continues to integrate new acquisitions such as Century Textiles and Industries into the business. By contrast Africa’s Dangote Cement has endured mixed fortunes so far 2019 with a modest rise in cement sales volumes and small drop in revenue and a larger decline in earnings in both Nigeria and operations elsewhere in Sub-Saharan Africa. At home this has been attributed to a subdued economy and elsewhere it has pointed to poor markets in South Africa, Zambia and Ethiopia. On the positive side though promotional marketing activity at home in Nigeria helped support an improved third quarter.

Summarising all of this is difficult given the very different nature of these large companies. Generally most of these companies are growing. One takeaway to consider is the emergence of two types of cement producer models at the top end: multinationals and large-local players. In recent years the rise of the large-local player has been a story mirroring the economic prominence of China and India. One can also see it in places like Indonesia and Brazil. The worry is that these kinds of companies are more exposed to regional economic risks than multinational ones. Yet in 2019 some multinational cement producers are also having problems. Whatever else happens, if fears of a new global recession come true, then these larger scale producer models will be tested, possibly to breaking point.
