Taiwan Cement said this week that it is aiming for cement to account for less than half of its sales by 2025. At the annual shareholders’ meeting chair Nelson Chang defended the cement sector as a core business but said that the company was expanding more into the green energy sector through its energy storage and vehicle charging lines. Chang directly linked the strategy to growing carbon taxes around the world, such as the European Union Emissions Trading Scheme, where the carbon price has been occasionally close to pushing past Euro100/t since early 2022. Taiwan Cement formed a joint venture with Türkiye-based Oyak Group in 2018 that runs Cimpor in Portugal.

Taiwan Cement’s plan to decrease its reliance on cement is becoming a familiar one. Holcim notably revealed in 2021 that it was growing its light building materials division. Its cement division represented 60% of sales in 2020 with concrete and aggregates making up most of the rest to 92% and the remaining 8% on other products including light building materials. This started to change with the acquisition of roofing and building envelope producer Firestone Building Products in 2021. Other similar acquisitions have followed. Holcim’s current target is to grow the Solutions & Products division to around 30% by 2025, with cement reduced to somewhere between a third and half of sales. Earlier this year Japan-based Taiheiyo Cement said it was doing a similar thing as part of its medium-term strategy to 2035. In its case cement represented 70% of its sales in 2022 but it is now aiming to reduce this to 65% by 2025 and 50% by 2035.

A common pattern for the business composition of European cement companies is a mixture of heavy building materials made up of cement, concrete and aggregate. However, not every cement company follows the same route. Some cement companies are simply parts of larger conglomerates. UltraTech Cement, for example, is mostly just a cement company. However, it is also part of Aditya Birla Group, which runs a wide range of industries including chemicals, textiles, financial services, telecoms, mining and more. Depending on how one looks at it, UltraTech Cement’s cement business ratio is large or Aditya Birla Group’s ratio is small. Siam Cement Group (SCG) in Thailand is another example of a cement producer operated by a conglomerate with other major businesses.

A different approach that some cement producers take is to mix cement production with complimentary businesses outside of heavy building materials. A good example of this is Votorantim Cement in Brazil, which manufactures cement and steel. Companhia Siderúrgica Nacional (CSN) is another Brazil-based cement producer that is also well known for steel production. Adani Group in India, meanwhile, was well known for logistics, power generation and airports before it purchased Ambuja Cements and ACC from Holcim in 2022.

The driver for cement companies looking to reduce cement as a proportion of their businesses has varied between the three examples presented above. Holcim’s approach has been in response to growing European carbon costs but it also fits with a general desire to broaden its business as the company has sought to reshape itself following the merger between Lafarge and Holcim. Taiheiyo Cement’s plans also have a sustainability angle but the Japanese market has been in slow decline since the 1990s and this has been made worse by the spike in energy prices since 2022. Investing in new businesses makes sense for either of these reasons. Lastly, Taiwan Cement says it is taking action in response to carbon prices around the world. However, its proximity to many other large-scale producers in the Far East may also be a factor. Whether more companies follow suit and also start to reduce the ratio of their cement businesses remains to be seen. Yet, mounting carbon taxes and global production overcapacity look set to make more of the larger cement producers consider their options in certain places.

France: The French cement association France Ciment has announced a new CO₂ emissions reduction target of 50% across the cement industry between 2021 and 2030. The new target for 2050 will be 'virtual carbon neutrality.' The Les Echos newspaper has reported that the commitments replace previous reduction targets of 24% by 2030 and 80% by 2050. France Ciment says that its members are planning estimated investments of Euro5bn towards achieving the goals before 2040. These investments will cover areas including the deployment of carbon capture. Existing public and private investments in the industry's on-going projects to reduce CO₂ emissions amount to Euro1.7bn - sufficient to eliminate 27% of emissions compared with the 2021 baseline.

France Ciment’s President Benoit Pillon noted the necessity of cement in construction, and called for 'decarbonisation as a whole: less clinker in cement, less cement in concrete and less concrete in construction.' He urged the implementation of policies to secure 'decarbonised and competitive electricity.'

France: Hoffmann Green Cement Technologies has commissioned its H2 plant, a 1000t/day clinker-free cement plant, adjacent to its existing H1 clinker-free cement plant in Bournezeau, Pays de la Loire. L'Usine Nouvelle News has reported that the new plant took 24 months to build and cost Euro22m. The main part of the plant consists of a 70m tower, where activated clay, ground granulated blast furnace slag (GGBFS) and gypsum are mixed to produce the cement. It is installed with solar panels capable of supplying 50% of its energy consumption. The producer says that its clinker-free cement has over 90% lower CO₂ emissions than cement produced with ordinary Portland cement (OPC). It aims to sell 24,000t of the product throughout 2023.

India: Ambuja Cements has placed orders with equipment suppliers for an 8Mt/yr clinker capacity expansion across two of its cement plants. The plants in question are the 2.9Mt/yr Bhatapara cement plant in Chhattisgarh and the 4.5Mt/yr Maratha cement plant in Maharashtra. Ambuja Cements will also build 42MW-worth of waste heat recovery (WHR) power capacity. The new cement capacity will be able to operate on renewable energy and use 50% alternative fuel (AF). As such, upon completion of the project, the plants will together produce 14Mt/yr of Ambuja Cements' reduced-CO₂ Blended Green Cement. The producer will fund the work through internal accruals, and expects to complete it in May 2025.

CEO Ajay Kapur said "These brownfield expansion projects are part of our strategy to double our production capacity over the next five years from the current capacity of 67.5Mt/yr. Our ongoing investments in capacity expansion and sustainability will enable us to achieve our long-term objectives, as we remain committed to delivering sustainable growth and value to our stakeholders."

Argentina: Cementos Avellaneda has signed a memorandum of understanding (MoU) with energy provider YPF Luz for the construction of a new wind farm. Local press has reported that the planned plant will have a capacity of 63MW and be situated in Olavarría, Buenos Aires Province. There, it will supply 100% of the energy used in cement production at Cementos Avellaneda's Olavarría cement plant. The cement producer will transmit any surplus energy from the wind farm to its San Luis plant at La Calera, with the longer-term aim of becoming Argentina's first 100% renewably-powered cement company.

The partners will carry out technical and economic feasibility studies in mid-2023, and publish plans and budget before the end of the year.

US: Holcim US has joined the Department of Energy's (DOE) 'Better Climate Challenge' to reduce CO₂ emissions and save energy. It is the first cement producer to commit to the DOE program. The subsidiary of Switzerland-based Holcim plans to power the electrical operations at 13 cement plants in the country with 100% renewable energy by 2030 and to reach net zero CO₂ emissions by 2050. As part of the 'Better Climate Challenge' it has committed to reduce CO₂ emissions in the US by at least 25% by 2033.

Examples of current renewable power usage at Holcim US cement plants include the installation of three onsite wind turbines at the Paulding plant in Ohio that generate 11,500MWh while a forthcoming solar unit at the Hagerstown plant in Maryland will generate up to 18,440MWh. All 13 Holcim cement plants will conduct reviews to identify projects that could contribute to meeting goals of the challenge.

With grant support from the DOE, Holcim is also investigating the feasibility of using carbon capture utilisation and storage (CCUS) at its cement plants in Portland, Colorado, and Ste. Genevieve, Missouri. In addition to involvement in the Better Climate Challenge, Holcim US is a continuing partner of the DOE's 'Better Plants Challenge', sharing facility-level energy data and solutions to help guide other industrial companies with implementing energy solutions in their facilities.

India: JSW Cement was among 20 companies from various industries in attendance at a roundtable discussion on the subject of leveraging clean energy to journey towards net zero on 13 April 2023. The discussion covered a broad range of ways to end the use of fossil fuels, including energy storage and the use of electric vehicles. Press Trust of India News has reported that advanced batteries developer Log9 Materials hosted the event in partnership with networking platform Blue Circle – not to be confused with the former cement producer of the same name. Executive director and chief risk officer Arvind Bodhankar represented Dalmia Bharat, while chief sustainability and innovation officer Manoj Rustagi represented JSW Cement.

Pakistan: Bestway Cement has ignited the kiln of Line 1 of its Mianwali cement plant in Punjab. The line has a capacity of 2.3Mt/yr. The Pakistan Observer newspaper has reported that it increases the producer's cement capacity by 18% to 15.3Mt/yr and brings its total number of production lines to eight. The Mianwali cement plant is equipped with a 20MW solar power plant and will run on 50% renewable energy. It also has a 9MW waste heat recovery (WHR) plant, an air cooled condenser (ACC) system and a rainwater harvesting system.

Bestway Cement CEO Lord Zameer Choudrey said "It's a great day for the company. Our new greenfield production line at Mianwali has been set up in a record time, despite various hurdles and supply chain disruptions caused by Covid-19."

Canada: The Cement Association of Canada (CAC) said that it is 'confident that Canada will lead in building clean technologies for a sustainable future' following the publication of the government's Budget 2023 on 29 March 2023. The budget includes US$26bn-worth of green tax credits. US$19.2bn-worth of this is allotted to renewable energy. It also includes a final design for Canada's Investment Tax Credit for Carbon Capture, Utilisation and Storage (CCUS). CAC president and CEO Adam Auer said that, when finalised, the budget will help to 'close the gap' between existing Canadian legislation and incentives offered under the US Inflation Reduction Act and EU Green Deal Industrial Plan.

Auer said “With close to 60% of our emissions resulting from the immutable chemistry of making cement, deep investment in innovative and expensive technologies, like CCUS, are both vital and unavoidable. With Budget 2023, the government clearly affirmed its understanding of the final role this technology plays in our industry’s efforts to reach net-zero." He continued “We were also pleased to see references to carbon contracts for difference (CCfD). Canada’s cement companies, like many industries in Canada, are part of large multinationals, and divisions must compete within their companies for projects. Investing in net-zero projects requires predictability. The certainty that CCfDs can provide is the difference between attracting investment, building projects and creating clean jobs - or conceding the opportunity to our competitors."

US: Buzzi Unicem subsidiary Alamo Cement Company has successfully commissioned its new 17,800MWh solar power plant at its San Antonio cement plant in Texas. The producer says that the facility will eliminate 8000t/yr-worth of CO₂ emissions from the plant's operations. It spans an area of 18.2 hectares at the site of the 1.1Mt/yr cement plant. Texas-based energy provider CPS Energy built the installation.

Alamo Cement's director of engineering and construction management William Kovacs said "I am incredibly proud of the multi-discipline work that went into this first-of-its-kind project for Alamo Cement in San Antonio. It is an example of the type of collaboration necessary to continue to unlock and apply new energy sources for cement producers. It was a collective effort that brought together our corporate team, CPS Energy and regional engineering firms and contractors."
