Peru: UNACEM Peru said that it reduced its CO₂ emissions per tonne of cement by 2.7% year-on-year during 2022. Throughout the year, the company reduced its electricity consumption by 3.4%. It sourced 90% of its electricity from renewable sources and met 70% of its fuel needs with natural gas. UNACEM Peru is committed to reaching carbon neutral cement production by 2050.

In terms of community engagement, the producer benefitted 76,700 people through its social infrastructure investments and 14,1000 people through its dialogue space initiatives, and provided its remote health guidance service to 3000 people.

Ethiopia: Derba MIDROC Cement is reportedly ready to sign a contract with China National Building Material (CNBM), for the latter to commence construction of Derba MIDROC Cement's 2.74Mt/yr Mughar Valley cement plant in Oromia. The producer said that it expects to invest US$500m in the project, 30% higher than its previous estimate of US$385m. Addis Fortune has reported that Derba MIDROC Cement now believes there to be adequate energy infrastructure to support the plant, following China-based Sinohydro's construction of a new US$12m power line from nearby Chanco.

When commissioned, the plant will double Derba MIDROC Cement's capacity and create 3000 new jobs in Oromia. The producer also hopes to ease the ongoing national cement shortage. The Ministry of Mines recorded domestic production of 7.6Mt in 2022, against demand of 36Mt.

Europe/India: Finland-based Betolar has secured EU-wide and Indian patents for a new waste-based alternative concrete produced without cement and capable of storing energy. Betolar said that the material, which is already patented in Finland, is especially suited for use in renewable energy infrastructure, where it can provide a storage solution for dealing with short-term peaks. Chief commercial officer Ville Voipio said that the company will now seek to establish a partnership for commercialisation of its new alternative building material.

Betolar produces and markets the Geoprime additive used to produce cement-free concrete from supplementary cementitious materials, including ground granulated blast furnace slag (GGBFS), in regions that include India and the EU.

Chile: Cemento Polpaico plans to invest US$67m in expanding its operations, with a focus on its Cerro Blanco cement plant in Santiago. Work will include the construction of a solar power plant and the expansion of the plant's limestone quarry. Meanwhile, Cemento Polpaico will upgrade the plant's kiln to increase its alternative fuel (AF) substitution rate to 75% from 13%. The upgrade will increase the production line's clinker capacity by 13% and reduce its CO₂ emissions by 20,000t/yr. Additionally, the producer will build a new 3000t cement silo.

Bolivia: State-owned gas and oil company YPFB has commenced gas supply to Potosí via its Sucre-Potosí gas pipeline, which underwent a 32% capacity expansion to 4.15Mm³/day. Página Siete News has reported that the expansion cost US$5.8m. YPFB said that it can now increase gas allocations in accordance with customers' contracts.

Empresa Publica Productiva Cementos de Bolivia (ECEBOL) is scheduled to commission its upcoming 1.3Mt/yr Potosí cement plant in June 2023. YPFB holds a contract to supply 337,000m³/yr of natural gas to the plant. YPFB says that the expanded Sucre-Potosí pipeline will help to boost cement production in Bolivia, both to supply domestic demand and to establish an export market.

India: Adani Group has taken a total US$2.33bn-worth of new loans over the two-and-a-half month period since the publication of a report into the group's activities by US-based shortseller Hindenburg Research on 24 January 2023. The report concluded with a finding of 'numerous issues of suspected fraud' by Adani Group. Adani Group explained at the time that all findings were 'stale, baseless and discredited.' The Times of India newspaper has reported that the group's net debt rose by 17% year-on-year to US$22.6bn on 8 June 2023. Adani Group's energy sector subsidiaries raised US$2.01bn-worth (86%) of the debt.

Adani Group completely paid off loans used in its US$6.4bn acquisition of Holcim India on 6 June 2023.

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.

UAE: Holcim subsidiary Lafarge Emirates Cement (LEC) has begun construction of a 10MW waste heat recovery (WHR) plant at its 3.2Mt/yr Fujairah cement plant. Supplier Engie Solutions says that it expects to commission the installation later in 2023. Trade Arabia News has reported that the equipment is based on a closed-loop organic Rankine cycle and will eliminate 29,000t/yr of CO₂ - 28% of the Fujairah cement plant's energy-related CO₂ emissions.

LEC general manager Olivier Milhaud said "Engie’s energy-as-a-service model means guaranteed energy savings and higher reliability and resilience, with no capital outlay and no need for additional staff." He continued "We are fully committed to the UAE’s sustainability goals, including the 2050 Net Zero vision."

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.'

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.
