Brazilian cement sales drop in first nine months of 2022
14 October 2022Brazil: Cement producers sold 47.7Mt of cement in the first nine months of 2022, down by 3% year-on-year from the same period in 2021. The Brazilian National Cement Industry Association (SNIC) has forecast a 2% year-on-year decline in full-year cement sales to 63.7Mt in 2022. The association foresees global finance-related challenges and high energy and raw materials costs during the fourth quarter of 2022. Annual cement sales previously grew by 23% to 65Mt in 2021 from 53Mt in 2019.
SNIC president Paulo Camillo Penna said “Our expectation for 2022 was to maintain the gains of this three-year period, but, unfortunately, due to high interest rates, indebtedness and cost pressure, we were not able to.”
Adani Group to establish US$70bn integrated hydrogen-based value chain
29 September 2022India: Adani Group plans to invest US$100bn in capital expenditure across all of its operations between 2022 and 2032. Mint News has reported that the conglomerate will establish 45GW-worth of new hybrid renewable power plants under the plans. It will also build three new green hydrogen plants, with a combined capacity of 3Mt/yr. It plans to support the latter move with an investment of US$70bn in the establishment of an integrated hydrogen-based value chain.
Heidelberg Materials considering shutting plants in Germany based on future energy prices
28 September 2022Germany: Heidelberg Materials says it is considering shutting down plants in Germany due to the high cost of gas and electricity. In comments reported by Reuters chief executive officer Dominik von Achten said, "If power prices won't come down sustainably, we would have to take individual plants in Germany completely off the grid. That's what we have prepared for." He added that the company is shifting production to times and days when power prices are lower including at the weekend. However, changing staff shift patterns has required ongoing discussions with labour unions.
The building materials company expects its energy bill to rise by around half year-on-year to over Euro3bn in 2022. It has called on the German government to place a cap on energy prices despite measures the company has already taken to protect itself from soaring costs, such as using alternative fuels.
Spain: Oficemen has blamed falling exports of cement on high electricity prices. The cement association reports that exports fell by around 25% year-on-year to 3.76Mt for the first eight months of 2022 from over 5Mt in the same period in 2021. Local consumption of cement slowed to an increase of just 0.2% to 9.88Mt from 9.86Mt.
Aniceto Zaragoza, the general director of Oficemen, said “Electricity costs in our sector have increased by 400% in the last two years, a situation that worsens every day due to the energy crisis we are suffering. Without competitive electricity costs, it is impossible for our industry, which for many years has led the cement export market, to continue competing with other producers in the Mediterranean area that pay much less for their energy inputs, such as Algeria, Turkey or Egypt.”
Electricity supplies to cement plants in Europe
07 September 2022Cembureau 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.
Belgium: Cembureau, the European Cement Association, has called for urgent action to be taken to support cement production due to large increases in the cost of electricity. It said that, if no measures were taken at both the European and national level, the current energy prices would lead to widespread plant closures across the European Union (EU). This in turn could create a crisis in the construction supply chain. It explained that one tonne of cement normally takes around 110kWh of electricity to produce. Therefore, with electricity prices now between Euro700 - 1000mWh, as observed in several EU member states, electricity costs amount to Euro70 – 110/t of cement, tripling the total cost of production.
The association has called for: all available sources of electricity generation to be used to boost power supplies; the immediate introduction of emergency measures, such as price caps; 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; and that co-processing in cement kilns should be actively encouraged and promoted at EU, state and local levels.
It added that further measures should also be considered, including: the electricity market design rules, including the marginal price setting mechanism, should be changed to prevent further electricity price hikes in the future; the cement sector should be made eligible for financial compensation under the EU emission trading scheme indirect state aid guidelines and that indirect emissions should be included in the EU Carbon Border Adjustment Mechanism (CBAM); the large-scale deployment of renewable energy should be supported across the EU; and that the pace of the EU climate agenda ('Fit for 55') should be maintained, and the CBAM should be implemented in a timely manner.
Sichuan Yadong Cement plant restarts following heat wave
05 September 2022China: Sichuan Yadong Cement’s plant in Sichuan has restarted production following a suspension of electricity to industrial users due to a heat wave. The local authorities stopped supplying industrial plants in late August 2022. The subsidiary of Taiwan-based Asia Cement Corporation also reduced staff levels at the plant to cope with the extreme weather event.
Cruz Azul’s Tula cement plant set to regain electricity supply
05 September 2022Mexico: Cooperativa la Cruz Azul’s Tula cement plant in Hidalgo has agreed with the Federal Electricity Commission (CFE) that electricity supplies will restored no later than 7 September 2022. Federico Sarabia, cooperative chair and leader of a dissident group claiming to own the plant, said that the plant has made losses of over US$15m due to the outage, according to the El Sol de la Laguna newspaper. The electricity supply to the site was reportedly cut in mid-August 2022 at the request of Víctor Manuel Velázquez, the head of the board of directors of the group.
State police intervened during a confrontation between rival groups for control of the Tula cement plant in late July 2022. The plant is the sole remaining Cruz Azul unit still reportedly controlled by former company director Guillermo ‘Billy’ Álvarez and his associates. The rest of the company is under the command of Cruz Azul’s directors José Antonio Marín and Víctor Manuel Velázquez. This group started asserting legal control of the cooperative’s cement plants in Puebla and Aguascalientes from mid-2020.
30% of Indian captive power plants close
15 August 2022India: 30% of plants in India’s 78GW captive power plant network have temporarily closed due to high coal prices. 40GW-worth of capacity (55%) is coal-fired, with an annual consumption of 200Mt/yr. The Business Standard newspaper has reported that total Indian coal imports fell by 10% to 23.8Mt in July 2021 from 26.3Mt in June 2021. Deliveries of coal to non-power sector consumers fell by 33% year-on-year at the beginning of August 2021. The Indian Cement Manufacturers Association (CMA) and nine other national industry associations have contacted the government to urge the formation of policies for the equitable distribution of available coal.
India Cements has imported two shipments of Russian coal for use in cement production. The company’s power and fuel costs rose by 54% year-on-year in the first quarter of its 2023 financial year, which began on 1 April 2022. Its vice-chair and managing director Narayanaswami Srinivasan said “Most of our plants have coal-based captive power generation. The cost of captive generation is now more than the grid cost. Hence, we shut down all captive power units and resorted to grid power.”
