UltraTech Cement, Taiheiyo Cement, Cimtogo and the Chinese Cement Association (CCA) have all been talking about the same thing recently: energy prices.

India-based UtraTech Cement reported this week that coal and petcoke prices nearly doubled in the second quarter of its current financial year, leading to a 17% rise year-on-year in energy costs. Japan-based Taiheiyo Cement released a statement earlier in October 2021 saying that due to mounting coal prices it was planning to raise the price of its cement from the start of 2022. It principally blamed this on increased demand in China and a stagnant export market. It added that it was ‘inevitable’ that prices would rise further in the future. Meanwhile in West Africa, Eric Goulignac, the chief executive officer of Cimtogo, complained to the local press that the reason the company’s cement prices were going up was due to a 250% increase in the cost of fuels for the Scantogo plant and an increase in the price of sea freight of over US$35/t for transporting gypsum and coal.

Other places where the cost of energy has been biting cement producers include Turkey and Serbia. In the former, Türk Çimento, the Turkish Cement Manufacturers' Association, warned in June 2021 that the price of petcoke had nearly tripled over the previous year. Whether it was connected or not, the Turkish Building Contractors Confederation (IMKON) organised a strike in September 2021 due to high costs. The confederation claimed that the price of cement had tripled over the last year. In Serbia electricity prices have risen sharply in recent months in common with much of Europe. Local press reported comments last month from President Aleksandar Vučić saying that an unnamed cement producer had warned of a 25% rise in the price of cement if electricity prices remained high. In the UK the Energy Intensive Users Group (EIUG), a network of lobbying groups for heavy industry including cement, has been holding talks with the government on how to cope with growing energy costs. Finally, in the US, Lhoist warned in September 2021 that is was going to increase the cost of all of its lime products from the start of November 2021 due to increasing gas prices. These are just some of the reactions by cement and lime producers to the current global energy market. No doubt there are many more.

The current global energy crunch has widely been attributed to the waking up of economies following coronavirus-related dormancy in 2020 with supply failing to meet demand. Gas prices have risen to record highs and this has promoted electricity producers to switch to coal in the US, Europe and Asia. This in turn has put pressure on industrial users as both electricity and coal prices have grown and governments have taken action in some cases to protect domestic users. In Europe price pressure has lead to reductions in ammonia and fertiliser production. Power cuts have been reported in China and India.

In China a variety of factors have converged to create a crisis. These include shutting down coal mines on environmental and safety grounds, anti-corruption measures and even promoting mine closures to facilitate clean skies for national events such as the Communist party’s 100th anniversary. Disruption to import sources such as a ban on Australian coal on political grounds, flooding in Indonesia and a renewed coronavirus outbreak in Mongolia can’t have helped either. Thermal coal futures traded on the Zhengzhou Commodity Exchange hit a high of US$263/t on 15 October 2021 marking a 34% rise through the week and the largest weekly growth since trading started in 2013. The International Energy Agency estimates that coal demand in China grew by over 10% year-on-year in the first half of 2021 but coal production increased by just over 5%.

Industrial users have suffered as energy supplies have been rationed and producers asked to cut output. In September 2021 cement output fell by 12% year-on-year to 205Mt from 233Mt in September 2020. This is the lowest monthly figure for September since 2011. It’s also not the usual direction of double-digit rate of change that the Chinese cement sector is used to. The CCA attributed this mainly to energy controls, power shortages and high coal prices in Jiangsu, Hunan, Zhejiang, Guangdong, Guangxi, Yunnan, Shandong and elsewhere. Cement output for the first nine months of 2021 is still ahead of 2020 at 1.77Bnt compared to 1.67Bnt but it’s been slipping noticeably since July 2021.

This will leave energy users, including cement producers, watching the weather forecasts rather closely this winter. Should the Northern Hemisphere suffer a cold one then energy prices such as coal will reflect it. Industrial users may also become subject to energy rationing in many places. The knock-on effect of this then will be higher cement prices. However bad the winter does turn out to be though we can expect more cement companies trying to explain bashfully why their prices are going up. On the plus side any producer that can diversify its energy mix through solar, alternative fuels or whatever else is likely to be doing so soon if they are not already.

Nepal: The Nepal Electricity Authority (NEA) has completed and commissioned a switching station to supply power for Huaxin Cement and Vaidya Group’s upcoming Dhading cement plant in Rorang. The Republic newspaper has reported that, when operational, the plant will receive 20MW of power via the switching station. Two transmission lines with capacities of 33kV and 11kV connect the facilities.

The US$125m Dhading cement plant awaits commissioning following the completion of its construction in August 2021.

India: Shree Cement has hired FLSmidth to supply a 11,5000t/day kiln line for its planned Nawalgarh, Rajasthan, cement plant. The line will consist of a six-stage preheater and a three-support kiln. The supplier will also deliver an OK vertical roller mill, which it says has a 5 – 10% lower energy consumption than a standard vertical roller mill. The project focuses on sustainable productivity and emissions control. Shree Cement has opted for JetFlex burners to give the lowest possible nitrous oxide emissions for various fuel types.

Shree Cement managing director Prashant Bangur said “Based on the experience of working with FLSmidth on the installation of a 9,000t/day pyro system at the Raipur, Chhattisgarh, cement plant earlier this year, we felt confident about approaching Carsten Riisberg Lund and his team regarding the Rajasthan project.” He added “Being recognised as a Sustainability Champion by the World Economic Forum is a testament of our emphasis on sustainability at every stage of our operations. The new line will push that agenda even further in terms of lowering the benchmarks on energy consumption and emissions, and thereby reducing our environmental footprint.”

FLSmidth also supplied a second OK mill for Shree Cement’s operations in Kolkata, West Bengal.

Poland: Cemex Poland has established a new 50kW solar power plant at its Pruszków ready-mix concrete production plant in Masovian Voivodeship. The company says that it is planning other investments to retrofit renewable energy systems into its operations across Poland.

Materials director Michał Grys said “Cemex is actively addressing the climate challenge by decarbonising our processes. The key to realising our ambitious goals is finding and implementing new low-emission products as well as more sustainable technologies and construction solutions.” He added “Photovoltaic farms are another investment by Cemex Poland in renewable energy sources. Currently, much of the electricity used in our aggregate quarries, cement plants and many concrete plants comes from renewable sources."

India: Udaipur Cement Work plans to increase its reliance on renewable power with the installation of a new 4.15MW solar power plant at its cement plant in Udaipur, Rajasthan. When operational, the installation will increase the Udaipur plant’s solar power capacity by 42% to 14.3MW. The producer says that its entire solar power apparatus will facilitate a reduction in CO2 emissions of 14,000t/yr. In the 2020 and 2021 financial years, the producer consumed 13,000MWh of solar power, reducing CO2 emissions by 10,000t.

Pakistan: DG Khan has connected its upgraded Hub cement plant and power infrastructure to the national grid. The Pakistan Observer newspaper has reported that the facilities generate 40MW of power via a 10MW waste heat recovery (WHR) plant and 30MW coal-fired power plant. China National Building Material (CNBM) subsidiary Sinoma Energy Conservation provided engineering, procurement and construction (EPC) services for both power plants.

US: The Portland Cement Association has announced the winners of the Energy Environment Awards 2020. Cementos Argos’ 1.1Mt/yr Harleyville, South Carolina cement plant won the Energy Efficiency Award “by reducing kiln specific heat consumption and increasing the utilisation of the new vertical cement mill,” while CRH subsidiary Ash Grove Cement’s 1.0Mt/yr Midlothian cement plant won the Environmental Performance Award for “operating a whole-tyre burning system utilising a first-in-the-US hot disk system supplied with whole tyres from a nearby tyre recycling company.” Other winners were GCC’s 0.9Mt/yr Odessa, Texas cement plant for Innovation, LafargeHolcim’s 2.2Mt/yr Holly Hill, South Carolina plant for Land Stewardship, Titan Cement's Roanoke Cement Troutville plant for Outreach and HeidelbergCement subsidiary Lehigh Hanson’s 3.2Mt/yr Union Bridge, Maryland plant for Overall Environmental Excellence.

PCA president and chief executive officer (CEO) Michael Ireland said, “America’s cement manufacturers continue to focus on researching and developing new and innovative ways to reduce environmental footprint. The companies receiving these awards are great examples of our industry’s commitment to sustainability and energy efficiency.”

Switzerland: LafargeHolcim has reported sales of Euro5.03bn in the first quarter of 2020, down by 11% year-on-year from Euro5.66bn in the corresponding period of 2019. Cement sales over the period fell by 10% year-on-year to 45.0Mt from 50.0Mt. The group’s earnings before interest and taxation (EBIT) was Euro249m, down by 14% from Euro290m.

LafargeHolcim CEO Jan Jenisch said that the results showed the group’s ‘resilience, despite the COVID-19 outbreak in China’ in January 2020. Other markets were disrupted from mid-March. “I am confident that LafargeHolcim will emerge from this pandemic as an important contributor to economic recovery as building activity gets back to normal,” he added.

LafargeHolcim’s coronavirus action plan consists of a Euro380m year-on-year capex reduction, a Euro285m year-on-year fixed cost reduction, realisation of energy price reductions, a review of all third party products and services and a reduction of net working capital in line with the level of activity.

Thailand: Germany-based KHD Humboldt Wedag has reported the successful commissioning of a new Comflex grinding line at Siam City Cement’s Plant 1 in Saraburi. The line replaces two ball mill circuits, maintaining a production capacity of 350t/hr with a 40% lower energy consumption. The Comflex comprises a roller press, RPM18–200/180 static coarse material separator, VS620 static fine material separator, LS8600 system fan, HKSK 236/346 and four product separation cyclones. KHD says that Siam City Cement awarded it the engineering, procurement and construction (EPC) contract because of the system’s low specific power consumption of 13.36kWh/t, compared to over 21kWh/t in the previous system.

Sweden: Refractories specialist Höganäs Borgestad opened its new headquarters at Gävle, Gävleborg county on 27 April 2020. The facility will house the Energy and Kiln Engineering, Installation and Management departments.

During the coronavirus lockdown one project of note for Höganäs Borgestad has been refractory maintenance at Germany-based HeidelbergCement subsidiary Norcem’s 1.2Mt/yr Brevik cement plant in Telemark, Norway, for which it supplied 600t of refractories and 45 workers over a three week period.
