Germany: Data from HeidelbergCement’s Sustainability Report 2020 reveals that it reduced its specific net CO₂ emissions by 2% year-on-year to 576kg/t of cementious material in 2020 from 589 kg/t in 2019. This represents a 23% reduction since 1990. The company has a target of 30% by 2025. It has a number of carbon capture and utilisation/storage (CCU/S) projects in various stages of development to meet its goal of becoming carbon neutral by 2050. Other data shows that its alternative fuels substitution rate rose to 25.7% from 24% and its clinker ratio fell slightly to 74.3%.

During the reporting year, the group joined the climate lobbying group Foundation 2° and achieving a CDP climate protection rating of A. For water security it secured the second-highest rating of A-. The group’s specific water consumption for cement rose by 5% in 2020 to 271.9l/t of cement from 260l/t in 2019. However the company says it is continuing to improve water consumption reporting at its sites until 2025.

Another week and it’s another commodity story related to the effects of coronavirus. This time the Indian press and financial analysts have started to notice a shift in the fuel mix of some of the major producers from petcoke to coal. UltraTech Cement moved to 30% petcoke and 60% imported coal in the fourth quarter of its 2021 financial year that ended on 31 March 2021. This compares to a reported mix of 77% and 10% in the previous year according to Mint. Dalmia Bharat reduced its share of petcoke to 52% in the fourth quarter from 70% in the third quarter, while its coal mix was 35 - 40% in the fourth quarter.

Price is the driver here. UltraTech Cement’s chief financial officer Atul Daga summed the situation up in an earnings call in late January 2021. Essentially, he said that fuel represented about 13% of total costs for cement producers in India and that both the cost of coal and petcoke nearly doubled from June 2020 to January 2021. However, coal is seen as the cheaper option, hence the move towards it in the fuels mix ratio. The petcoke market meanwhile has suffered due to reduced oil refinery output due to, you guessed it, the effect of coronavirus on global markets in 2020. Scarcity in the US market has particularly affected the decisions on buyers for Indian cement companies since this is the key source of their imports. Demand for petcoke from Latin America and the Mediterranean hasn’t helped either. Both petcoke and coal markets are expected to stabilise in the second half of 2021. Diesel prices have also risen recently causing UltraTech Cement’s power and fuel costs to increase by 28% year-on-year to US$356m and logistics costs, including freight expenses, to rise by 25% to US$449m in the fourth quarter of its 2021 financial year.

With this in mind it’s interesting then, that for some analysts at least, fuel prices have been seen as more worrying for cement producer profits than the latest round of coronavirus-related lockdowns from India’s second wave of infection. Fitch Ratings for example, warned that the impact of mounting fuel costs would continue to be seen in the quarter to June 2021 but that it would subside due to the switch in fuel mix and price rises passed to end consumers. On the lockdowns, it forecast that localised restrictions, with cement plants being allowed to continue operating in most states, would cause a far less pronounced drop in cement demand than during the first national lockdown.

Graph 1 above shows that the crisis the Indian cement sector faced during the first lockdown, when production crumbled by 85% year-on-year to 4.3Mt in April 2020. The following recovery saw production reach its second highest ever figure at 32.9Mt in March 2021. It’s too soon to tell what’s happening from the national figure but that dip in April 2021 is not looking good so far.

One benefit from unstable fuel prices is that it builds the economic case for cement producers to raise their alternative fuels substitution rates. UltraTech Cement, for example, reported that its ‘green’ energy rate grew to 13% in its 2021 financial year from 11% in 2020. With a target of 34% by its 2024 financial year, this is an ideal opportunity for a change for both UltraTech Cement and other producers.

Sweden: Germany-based HeidelbergCement subsidiary Cementa plans to upgrade its Slite unit in Gotland to become the world’s first carbon-neutral cement plant. This will be achieved through modification of the plant’s fuel system to ‘significantly raise’ biobased fuel substitution, as well as 100% carbon capture and storage (CCS) via a 1.8Mt/yr CCS installation. Full-scale capturing of the plant’s CO₂ emissions is scheduled by 2030.

Chair Dominik von Achten said, “HeidelbergCement will be the leader in the global cement industry on its transformation path towards climate neutrality. The key for decarbonising our industry is to find, apply and scale technical solutions for carbon capture and utilisation or storage (CCU/S). After having gained valuable experience with CCU/S technologies in Norway and other countries, we are now excited to make the next step with a completely carbon-neutral cement plant in Sweden.”

Portugal: Denmark-based FLSmidth has won a contract to supply a chlorine bypass system to Cimpor’s Souselas cement plant. The aim is to eliminate chlorine build-up in the plant’s flue gas after the company increases its refuse-derived fuel (RDF) usage rate to 60%. Work is scheduled to begin in mid-2021, and production will stop until its completion and the commissioning of the installation in early 2022. No value for the order has been disclosed.

Cimpor Cement project manager Paulo Evangelista said, “Investing in the chlorine bypass is a key step on our journey towards reducing our environmental footprint. On top of the obvious incentives to increase our fuel substitution, like lower CO₂ emissions and financial savings, we are experiencing better waste handling infrastructure in the local area. All this has made it an easy choice to make. FLSmidth knows our Souselas site and has been key in delivering a solution that will enable this next phase on our sustainability journey.”

Taiwan: Taiwan Cement’s revenue rose by 11.3% year-on-year to US$788m in the first quarter of 2021. Its income increased by 11% to US$119m. It attributed this to profit growth in its cement businesses in Taiwan and Europe despite ‘weak’ sales prices in China.

Chairman Nelson Chang said, “To reduce carbon emissions, using alternative fuel and material for cement production, adopting renewable energy, and expanding energy storage usage are crucial and Taiwan Cement aims to play our role in helping society achieving the goal of a low carbon environment.” In 2020 the group processed over 9Mt of alternative fuels in its Greater China business.

Spain: Cemex España reopened its Lloseta cement plant in Majorca in mid-April 2021. The unit will start by operating at a low production level until demand levels build, according to the El País newspaper. The plant intends to use alternative fuels such as biomass to reduce its CO₂ emissions. It is also working with the Power to Green Hydrogen Mallorca project to use ‘green’ hydrogen created partly using solar energy. The plant now employs 20 people, compared to 96 before its closure in January 2019.

US: The California Nevada Cement Association (CNCA) has published a plan for the Californian cement industry to meet its target of carbon neutrality by 2045. The plan consists of three pathways, namely: a reduction in process emissions including by alterations to clinker factor and type of additives; an increase in alternative fuel (AF) substitution; and a switch to renewable energy. The association said that the aims are achievable by close stakeholder coordination, constructive public policy engagement and a situational approach based on a flexible portfolio of pathways.

Hungary: Lafarge Hungary, part of LafargeHolcim, has awarded a contract to Germany-based Loesche subsidiary A TEC for the supply of an alternative fuel (AF) flash dryer for the 1.0Mt/yr kiln line at its Királyegyháza cement plant in Baranya county. The supplier says that the dryer will use residual hot gas from the chlorine bypass system in conjunction with a satellite burner for firing the material in the kiln. The project also includes the installation of a new AF receiving, handling, and dosing system for a second AF flow firing directly into the kiln burner. A TEC says that it will commission the project in the second quarter of 2021 after the end of the plant’s 2020/2021 winter shutdown.

Europe: Cemex commissioned seven new bolt-on investments across Europe in January 2021. The company says that all of the investments are aligned to its key priorities of climate action, sustainable construction and earnings before interest, taxes, depreciation, and amortisation (EBITDA) growth. They include advances in fossil fuel reduction, lower CO₂ footprint products, circular economy investments and products that demonstrate life cycle CO₂ and energy consumption advantages for buildings. It made various changes at its cement plants, for example the installation of a new alternative fuel (AF) system in the Czech Republic. In France and the UK, it made circular economy and recycling improvements, and shifted to lower-CO₂ cement production in Croatia and lightweight concrete production in Spain. Additionally, it made efficiency upgrades to sites in Spain and the UK.

Europe, Middle East and Africa regional president Sergio Menendez said, “We have made a strong start to our 2021 ambitions to both grow our business and improve our climate impact. In 2020, we achieved our ambition of a 35% reduction in our CO₂ emissions compared to our 1990 baseline in Europe. We are also the first company in our sector to align our Europe operations to the EU aspiration to reduce CO₂ emissions by at least 55% by 2030. These investments represent further advances towards this 2030 target, as well as to deliver net zero CO₂ concrete globally by 2050.”

Italy: Cementir Holding recorded revenues from sales and services of Euro1.22bn in 2020, up by 1% year-on-year from Euro1.21bn in 2019. Cement and clinker volumes rose by 13% to 10.7Mt from 9.49Mt. Volumes registered the sharpest increase in Turkey, of 39%. Ready-mixed concrete (RMX) volumes grew by 7.8% to 4.4Mm³ from 4.1Mm³. The company maintained its 2019 earnings before interest, taxation, depreciation and amortisation (EBITDA) levels of Euro264m. It said that an improvement in performance in Turkey, Denmark, Egypt, China and Sweden balanced out negative effects on earnings in Belgium, US and Malaysia.

Chair and chief executive officer Francesco Caltagirone said, “In 2020, despite the serious pandemic, the group showed significant resilience with a 13% increase in cement volumes sold and revenue reaching the historical record. On a recurring basis, EBITDA increased by 2%, EBIT was up by 4% and yearly cash generation was Euro119m."

Under Plan 2021 – 2023 Industrial Plan, the company says that it envisages sales growth of 20% to Euro1.47bn and EBITDA growth of 29% to Euro340bn in 2023 compared to 2020 figures. It said that digitalisation investments begun in 2019 will contribute an expected Euro15m to EBITDA in 2023. As part of its sustainability commitments it has set a CO₂ emissions reduction target of around 30% by 2030, with emissions below 500kg/t of grey cement. However, it said that under the future European Taxonomy criteria white cement emissions are not included.

The group is planning to invest around Euro107m from 2021 to 2023 on sustainability and digitalisation. This includes a the construction of a new calcination plant in Denmark for the production of its Futurecem product and, the installation of wind turbines with an installed capacity of 8.4MW. It is also planning to increase the alternative fuels substitution rate at its integrated Gaurain plant in Belgian to 80% from 40% and invest in the use of natural gas and biogas in some of its plants.
