El Salvador: Holcim El Salvador says that the upcoming solar power plant at its El Ronco cement plant will have a capacity of 21.4MW, across three separate installations. Energy provider AES El Salvador holds a 20-year power supply agreement for construction and operation of the plant. The La Prensa Grafica newspaper has reported that Banco Cuscatlán supplied a loan for the project. When operational, the new solar power plant will lower Holcim El Salvador's oil consumption by 43,000 barrels/yr.

Holcim El Salvador CEO Rodrigo Gallardo said "We are not only making solutions and products with a lower CO₂ content, but also cutting CO₂ in our production processes."

US: SLB has launched EcoShield, a geopolymer-based well cement product. The company, also known as Schlumberger, says that the product cuts out up to 85% of embodied CO₂ emissions compared with conventional well cementing systems because it does not use ordinary Portland cement (OPC). It also reduces transport related emissions by using locally-sourced natural materials and industrial waste streams in its composition. The company says that the cement-free system can be deployed throughout various phases of the well life cycle, including abandonment. It can also be deployed across a range of field applications, including corrosive environments.

Jesus Lamas, SLB’s president of Well Construction, said “Decarbonising the well construction process while ensuring safety and performance standards is critical to our industry’s pathway to net zero.” He added “The cement-free EcoShield system is a breakthrough that delivers industry-standard zonal isolation capabilities while significantly minimising impacts from upstream oil and gas production.”

EcoShield has been tested by Pioneer Natural Resources in the Permian Basin on an 18-well field testing campaign and its use is ongoing.

Canada: Progressive Planet is preparing to build a 3200t/yr pilot plant for its PozGlass product at its headquarters in Kamloops, British Columbia. The company aims to commercialise its process, which produces pozzolan from recycled glass for use in cement or concrete production. The pilot unit will also sequester CO₂ released by a gas dryer at the site, from which it will produce sodium carbonate. The pilot plant is expected to go under construction in 2023 and be operational in 2024.

Steve Harpur, the chief executive officer of Progressive Planet, said “With PozGlass, a CleanTech breakthrough from our C-Quester Centre of Sustainable Innovation in Kamloops, we are producing one of many upcoming private-sector solutions that are needed to meet the 2050 Net Zero targets to fight climate change.”

Progressive Planet aims for PozGlass production to be situated at cement kilns, where PozGlass could be mixed with Portland cement at a 50:50 ratio.

France: CRH subsidiary Eqiom expects to complete its carbon capture system installation and kiln upgrade at its Lumbres cement plant under the EU's K6 Programme in early 2028. The project uses Air Liquide's capture technology, whereby purified CO₂ is liquefied for storage or use in building materials production.

China/Uzbekistan: Anhui Conch has released an update on some of its major development projects. Its new plant at Tashkent in Uzbekistan has an investment of around US$260m. The company reports that 30,000m² of equipment and materials have arrived, the rotary kiln supporting wheels have been hoisted in place, the main body installation of the coal mill has been completed, the structure of the dormitory building has been capped and the main factory area has begun to take shape. It is also building a plant at Brakbash District in Andijan State. Civil engineering and main engineering construction are reportedly underway. The company also has a third cement plant in the country. So far the group has built over 10 cement plants outside of China.

In China, Anhui Conch is building a CO₂ energy storage demonstration project at its Baimashan cement plant in Wuhu, Anhui province. The group says that, once complete, the project will be the world's first commercial demonstration project of a CO₂ energy storage system. It says that during the low power consumption period, the excess power will be used to compress CO₂ at normal temperature and pressure into a liquid. The heat energy generated during the compression process will be stored. The stored heat energy will then be used to heat the liquid CO₂ back into a gas, driving the turbine to generate electricity, reducing the cost of electricity. The demonstration project has an area of 40,000m².

The cement producer says it is working towards a model of ‘one base and five industries’ where cement production links to other industries such as new energy, new materials, environmental protection, the digital economy and the promotion of international trade.

Australia: Adbri reported a full-year rise in sales of 8.5% year-on-year to US$1.15bn in 2022 from US$1.06bn in 2021. Its earnings before interest and taxation (EBIT) fell to US$106m, down by 10% from US$118m. The producer said that its cement sales rose by 6.3% year-on-year. Demand remained ‘solid’ in Western Australia, while sales dropped in Southern Australia, partly due to wet weather and the loss of an exclusive supply contract. Adbri noted that “The backlog of residential construction works, attributed to the shortage of trades and wet weather in 2022, will continue to underpin good order books in 2023.”

The group said “The past year has been one of the most challenging for the company in its long history. Our results were delivered against the backdrop of a difficult macroeconomic environment, which included the global economic instability resulting in inflationary pressures and wet weather events across Australia. The company also underwent a substantial leadership transition in the latter part of the year, with the former managing director and chief executive officer (CEO) and chief financial officer stepping down from active duties as the company accelerates its transformational agenda.”

In 2022, Adbri achieved a 12% reduction in operational CO₂ emissions compared to 2019. Chief executive officer Mark Irwin called on the national government and state governments to embed CO₂ emissions reduction targets in legislation, and on the former to implement a carbon border adjustment mechanism on imported cement. Irwin noted that failure to implement such measures may lead lower-emitting plants such as the Birkenhead, South Australia, cement plant to transition to grinding imported clinker or consider closure.

Germany: The Science-Based Targets Initiative (SBTi) has validated Heidelberg Materials' new 2030 CO2 reduction targets. The targets have a base year of 2020 and conform to a 1.5°C climate change framework. Per tonne of cementitious material, the producer is now committed to reducing its Scope 1 CO2 emissions by 24%, its Scope 2 CO2 emissions by 65% and its Scope 3 emissions by 25%.

Heidelberg Materials' chief sustainability officer Nicola Kimm said “As reflected in our updated Sustainability Commitments 2030, climate action is a crucial element of Heidelberg Materials’ sustainability strategy. The SBTi validation shows that our sustainability agenda not only includes the most ambitious reduction target in the cement industry – but also a realistic, measurable plan in line with the 1.5°C scenario. We follow a clear, science-based approach, reducing our carbon footprint through the levers of product and process innovation and industrial-scale carbon capture, utilisation and storage. By closing the carbon and material loops, we will lead the sustainable transformation of our sector.”

In 2019, Heidelberg Materials became the first cement company to secure SBTi validation for its emissions reduction commitments.

Spain: Cemex España will install a carbon capture system at its Alicante cement plant in Valencia, as part of its efforts to make the unit a 'benchmark pioneer low-CO₂' cement plant. The producer holds a contract with ET Fuels for the supply of 45,000t/yr of CO₂ captured at the facility for methanol production.

Chief executive officer Fernando González said “Our goal of reaching net-zero CO₂ emissions is achievable and will be driven by collaboration and innovation. Our decarbonisation roadmap includes reducing emissions to the lowest possible level through proven levers such as clinker substitution and alternative fuels. New levers, such as rapidly developing CCUS initiatives, must effectively tackle the remaining CO₂ emissions to hit our ambitious 2050 objectives.”

Europe: Cemex’s annual CO₂ emissions from its European operations fell by 41% in 2022 compared to 1990. It added that it had cut its emissions in the region by 12% between 2020 and 2022. The group attributed the decline to the success of its climate action strategy to date, including a large investment in a new alternative fuels facility in the UK, investments in solar power plants in Germany and Poland and the roll-out of its Vertua reduced-CO₂ products across the region.

Regional president Sergio Menendez said "As we begin to implement the next stages in our climate action strategy, we now expect to exceed our 2030 aspiration of hitting a 55% CO₂ reduction in our European operations. While we are progressing important carbon capture projects and policy advocacy for our ultimate net zero target, these 2030 interim aspirations are not reliant on this technology.” he continued, “This is certainly a challenging target, but I am confident that with innovative thinking, close collaboration between our different business areas and further development of our regulatory framework, it is both feasible and profitable. This sustained effort is vital if we are to meet our global, primary objective of becoming a net-zero CO₂ company by 2050. We will continue to provide regular updates on our progress.”

Germany: Heidelberg Materials' sales increased by 13% year-on-year to Euro21.1bn in 2022 from Euro18.7bn in 2021. This was despite a 6.1% drop in cement and clinker volumes, to 119Mt from 127Mt. Heidelberg Materials' cement and clinker volumes fell by 10% in Western and Southern Europe, by 7.8% in Northern and Eastern Europe-Central Asia, by 14% in North America, by 1.3% in Africa-Eastern Mediterranean Basin and by under 1% in Asia-Pacific. The group's materials costs rose by 23% to Euro21.4bn from Euro18.8bn. Meanwhile, its profit dropped by 9.4% to Euro1.72bn from Euro1.9bn.

Chief executive officer Dominik von Achten said "It’s evident that we can only be profitable in the long term by shaping our future as a company in a climate-compatible way, further reducing the footprint of our products and closing material loops. We are making good strides in all areas. Compared with the previous year, we were able to reduce our specific net CO₂ emissions by another 2% in 2022. Our carbon capture, utilisation and storage projects launched worldwide are progressing favourably. At our CCS project in Brevik, Norway, we are well on track with the construction of the world's first CO₂ capture plant in our industry, and we look forward to commissioning in 2024." Von Achten continued "We have made a good start to 2023. The fourth quarter showed that we have laid a good foundation for the development in this year. Volatility on energy and raw material markets remains high, but the current easing in energy prices is giving us some breathing room. On the demand side, government infrastructure plans should compensate for the decline in private housing construction. We are optimistic about the further course of the year.”
