The data on cement consumption for 2021 in Spain is out this week and it looks promising. As the national cement association Oficemen explained, last year was the sector’s best for over a decade, nearly reaching 15Mt consumption and exceeding the figure in 2019 before the Covid-19 pandemic started. Oficemen also singled out particular strong performance in December 2021. It now expects this growth trend to continue into 2022 with a forecast of 5% to 15.6Mt predicted based on both domestic and infrastructure segments.

The Spanish cement industry reached a peak consumption of over 50Mt in the late 2000s before hitting a near-50 year low in the 2010s in the wake of the 2008 financial crisis. The market then started to recover in the second half of the 2010s until Covid-19 came along. A report on the Spanish cement market to the start of 2021 that lays out the situation can be found in the February 2021 issue of Global Cement Magazine. The larger news stories since then have been Votorantim Cimentos’ growth in the market through its acquisitions of FYM and Cementos Balboa, and Çimsa Çimento’s final completion of its deal to buy the Buñol white cement plant from Cemex. Each of these stories involve an integrated cement plant changing ownership.

Looking back at Oficemen’s summary describing 2012 depicts a much different dwindling market. However, one commonality it shares with the association’s roundup for 2021 is that it complains about the country’s disadvantage in electricity costs compared to its neighbours. Back in 2012 this was framed as holding back exports. As Oficemen noted at the time it exported 5.9Mt of cement in 2012, less than half the 13Mt it exported in 1983. Jump forward to 2021 and exports are now 6.8Mt. Energy is still a key issue though. Now Oficemen’s president, José Manuel Cascajero Rodríguez, says that the sector’s production costs have increased by 25% since the latest round of electricity price rises began. He then compares the cost of energy intensive industry in Spain unfavourably against France and Germany and calls for a structural change in the Spanish electricity market to make prices more predictable. Cement producers elsewhere in Europe and beyond may share Oficemen’s concerns regard unpredictable energy prices over the last six months but electricity has been a particular issue for Spain for a long time. To take one recent local example, in November 2021 Cementos Cosmos said it was planning to scale down the production of clinker at its Córdoba cement plant as a result of the high cost of electricity.

The other issue that gets raised in Oficemen’s 2021 summary is competition from cement importers outside the European Union (EU) and the necessity of a border carbon adjustment mechanism (CBAM) to take in account carbon taxation for producers within Europe. To jump back a bit, back in May 2021 the EU Emissions trading Scheme (ETS) reached Euro50/t. Then in December 2021 Cembureau, the European cement association, published a calculation predicting that if the EU ETS CO₂ cost made it to Euro90/t then this could represent 12 - 15% of the production costs of cement producers. Well, as readers will have guessed, the EU ETS beat Euro90/t on 2 February 2022 and then rose to Euro96.7/t on 7 February 2022. Answers in an email for when readers think the EU ETS price will top Euro100/t.

All of the above feeds neatly into the week’s other big Spanish news story: Cemex and Synhelion have successfully produced clinker from concentrated solar radiation at a pilot unit at the Very High Concentration Solar Tower of IMDEA Energy near Madrid. It’s early days yet as the process needs to be scaled up but, make no mistake, this is a big story. An interview with the team behind Cemex and Synhelion’s solar concentration project can be found in the December 2020 issue of Global Cement Magazine for more information. The SOLPART (Solar-Heated Reactors for Industrials Production of Reactive Particulates) project in France did similar research a few years ago but it didn’t reach the 1500°C target required to reach the sintering phase where clumps of clinker form. US-based Heliogen has been trying to industrialise concentrated solar energy but not much has been heard about its cement-industry ambitions since it said it reached temperatures of about 1000°C in 2019.

The relevance of an eventual full-scale concentrated solar unit for the entire production line or just the preheater and/or calciner at a cement plant in Spain makes considerable sense. At a stroke energy costs are reduced, diverted to a renewable source and any desired CO₂ capture becomes, in theory, easier and cheaper. Cemex said in the interview with Global Cement Magazine that the tentative next step would be a pilot unit at a cement plant, although, candidate plants could be in the US or Mexico, as well as Spain. Another side of the drive to cut energy and carbon costs can also be seen in a couple of photovoltaic solar projects supplying cement plants that were announced in 2021 for Spanish plants run by Cemex and Cementos Cosmos.

We leave the Spanish cement sector in a growth phase but with plenty of challenges ahead, not least from electricity costs and the mounting cost of carbon. Yet in common with other countries in Europe the industry faces a high-wire balancing act between staying economically viable and inching towards net zero. It’s conceivable that an industrial scale concentrated solar unit at a cement plant in Spain by 2030 might steady the wobbles along the way.

Canada: TransAlta Corporation has secured a contract to supply 100Gwh/yr of wind power to Lafarge Canada’s Exshaw, Alberta. The power will cover an estimated 25% of the plant’s electricity needs.

Lafarge Western Canada’s head of sustainability and environment Cailee Ellis said “This agreement, first of its kind for Lafarge in Alberta, is an important step to utilising higher amounts of renewable electricity at our facilities.”

Kenya: Bamburi Cement has signed a power purchase agreement (PPA) with Momnai Energy to set up two solar plants. One 14.5MW unit will be situated next to its integrated Mombasa plant and the other 5MW unit by its Nairobi grinding plant. This will account for up to approximately 40% of the cement producer’s total power supply. Construction of the solar power plants is scheduled to begin end of 2022, after requisite regulatory approvals with expected completion within a year.

“We are elated to be making this step towards switching to more affordable and clean energy that will not only lead to a significant reduction in power costs but also bring us closer to our goal of achieving net zero carbon emissions,” said Miriam Ngolo, Bamburi Cement’s Strategy and Business Development Director.

Other recent sustainability work by the subsidiary of Switzerland-based Holcim has included substituting heavy fuels with alternative fuels like biomass, including rice husks, and other waste material such as waste tyres and waste oil in its operations.

India: Dalmia Cement (Bharat) has commissioned a 14.7MW solar power plant at its 1.3Mt/yr Kapilas grinding plant in Odisha. The producer says that the new power plant multiplies its total solar power capacity in Cuttack District by six to 17.1MW from 2.4MW.

The company said "Furthering Dalmia Cement (Bharat)'s sustainability goal of becoming carbon negative by 2040, this initiative will enhance the plant's energy efficiencies."

Pakistan: Power Cement has signed an agreement with Burj Solar Energy for the procurement of electricity on a fixed tariff for the next 20 years. The supplier plans to build a 7MW solar power plant to support the deal. The unit is expected to be operational by mid to late 2022. Power Cement said it took the decision to cut growing electricity costs.

Singapore: Pan-United Concrete has started a partnership with Surbana Jurongto study the feasibility of using electric and hydrogen fuel cells to power a fleet of more than 1000 trucks. The agreement is intended to support Pan-United’s sustainability targets to offer only low-carbon concrete by 2030, carbon-neutral concrete products by 2040 and to become a carbon-neutral ready-mix concrete company by 2050.

Yeo Choon Chong, the Chief Executive Officer of Surbana Jurong's Association of Southeast Asian Nations division, said, "We applaud Pan-United's ambition to decarbonise its heavy vehicle fleet and are excited to contribute to its sustainability initiative by leveraging our expertise in electrification and hydrogen solutions. Partnerships are a key method of accelerating our collective efforts to build for a safe, sustainable and resilient future for all."

Nepal: The Nepal Electricity Authority (NEA) has agreed to supply ten industrial users, including cement producers, with an additional 151MW of electricity as part of a drive to increase domestic consumption. The cement producers concerned include Maruti Cement, Huaxin Cement, Hongshi Shivam Cement and Arghakhanchi Cement, according to the Republica newspaper. The other industrial users are mostly steel producers. In addition another 111MW is in the final stages of being allocated by the NEA to seven other industrial plants and a further 99MW has been identified for further distribution to industrial users. The government-supervised power supplier and distributor has identified around 500MW of wasted electricity supply due to low domestic consumption and a lack of transmission lines.

Mexico: 200 police officers in 80 police cars arrived outside the gates of Cooperativa La Cruz Azul’s Cruz Azul cement plant in Tula, Hidalgo, on 15 December 2021, but failed to enter the plant. The El Financiero newspaper has reported that the police were following a court order to remove the company from the plant. Supervisory board president Alberto Lopez reasserted the company’s right to occupy the property in line with federal government ordinances. Lopez suggested an alleged collusion between cooperativists and Omar Fayad’s Institutional Revolutionary Party (PRI) Hidalgo state government to decieve the courts.

Authorities have frozen Cooperativa La Cruz Azul’s accounts with outstanding bills of US$800,000 in electricity, gas, equipment and services bills, as well as the payroll of its 1100 workers.

Coopertiva La Cruz Azul chair Federico Sarabia said that the developments threaten the existence of the Cruz Azul plant. He said "In terms of quality, Cruz Azul’s cement exceeds the standard. At the time that Cruz Azul disappears as a cement producer, prices will increase.”

Europe: Cembureau, the European cement association, has calculated that if the European Union (UN) emissions trading scheme (ETS) CO₂ cost reaches Euro90/t then this could represent 12 - 15% of the production costs of cement producers. The association made its calculation for an average cement plant in the region using data from Ecorys, WIFO, the National Institute of Economic and Social Research for the EU Commission and Agora Energiewende.

Cembureau has called for the EU government to delay its proposed ETS free allocation phase-out and to bring forward the implementation of its proposed carbon border adjustment mechanism (CBAM) from 2026. It has called on policy makers to ‘use all the tools available to stabilise market prices, support energy intensive industries through state aid and examine the functioning of the European gas and electricity markets, as well as the EU ETS.’

India: Finance company ICRA reported all-India cement sales in the first half of the 2022 financial year of 124Mt, up by 22% year-on-year. Mint News has reported that the total value of cement sales rose by 5% in the period compared to the first half of the 2021 financial year. Producers’ raw materials costs rose by 16%, while power, coal and petcoke costs rose by 26% and freight costs rose by 7%. Granulated blast furnace slag (GBFS) and gypsum prices also rose.

ICRA corporate ratings assistant vice president and sector head Anupama Reddy said "Despite some easing in the cost-side pressures, the input costs are likely to remain elevated in the near term, and are expected to exert pressure on operating margins, which are likely to decline by 200 to 230 basis points (BPS) in the 2022 financial year as a whole. While the capacity additions are expected to increase year-on-year in the 2022 financial year, the reliance on debt is likely to be lower owing to the healthy cash generation and strong liquidity of the cement companies. The debt coverage metrics are expected to remain strong in the 2022 financial year."
