Canada: Lehigh Cement and Enbridge have announced a memorandum of understanding to collaborate on carbon storage for the integrated Edmonton cement plant in Alberta. Captured emissions will be transported via pipeline and sequestered by Enbridge. Lehigh Cement says it is developing North America’s first full-scale carbon capture, utilisation and storage (CCUS) unit for the cement industry at its Edmonton plant, with the goal of capturing approximately 0.78Mt/yr of CO₂.

Pipeline company Enbridge intends to apply to develop an open access carbon hub in the Wabamun area, west of Edmonton in conjunction with Lehigh Cement and Capital Power, as part of the Government of Alberta's Request for Full Project Proposals process. Once complete the Open Access Wabamun Carbon Hub would be among the largest integrated CCUS projects in the world. Subject to the award of carbon sequestration rights and regulatory approvals, the project could be in service as early as 2025.

Europe: A forthcoming report by consultancy CemBR has forecast that the European cement industry could potentially face carbon related costs of over Euro1.5bn in 2022 if production continues at 2020 levels or earlier. It looks at the performance of the European cement sector and the impact of the Phase IV of the European Union (EU) Emissions Trading Scheme ( ETS), which started in January 2021. Other key findings include that the sector reduced its carbon emissions per tonne of clinker by a 0.4% compound annual growth rate (CAGR) to the end of Phase III of the scheme.

The commercial market report has analysed the performance of each individual clinker producing plant in the scheme (including the UK) and has compared the end of Phase III with the beginning of Phase IV. It has also detailed the level of free allowances for part one of Phase IV and undertaken several analytical scenarios. Part one, running from 2021 to 2025, of Phase IV allowances for the whole scheme are around 16% lower than the 2020 level. Allowances have remained unchanged for this period but further ‘significant’ reductions are expected for part two of Phase IV. CemBR also reports that not all member countries are in the same position with regard to Phase IV with some countries exposed to more risk. In addition, there is a wide range of vulnerability with regards to carbon among the 201 operational clinker producing plants even within the same market.

The ‘EU ETS & Cement - Enter the Phase IV’ report is due to be published in February 2022.

Senegal: France-based Fives has detailed the equipment that it will supply for its construction of a new 6500t/day kiln line at SOCOCIM Industries’ Rufisque cement plant in Dakar Region. The company says that it will supply a preheater, in-line Preca calciner, kiln, TGT filter and Pillard Novaflam burner.

SOCOCIM Industries’ parent company Vicat’s chair and chief executive officer Guy Sidos said “Vicat Group renews its partnership with Fives Group through this major project of building a new line with a strong local dimension, employing local workers and contractors.” He added “This plant will eventually eliminate the use of fossil fuels, reduce our energy consumption and support Senegalese local development, making a higher quality product while doubling our production capacity.”

Switzerland: Holcim has successfully issued two sustainability-linked bonds worth US$355m and US$109m in the Swiss market. The group says that the issuances are another way in which it keeps climate action at the heart of its financing strategy. It brings the total sum raised by Holcim through sustainable financing agreements to US$7.33bn. Investors will be entitled to a higher coupon if the company does not achieve its climate objective.

Chief finance officer (CFO) Géraldine Picaud said “We are proud to be the first company to launch a sustainability-linked bond on the Swiss franc market. The bond attracted new environmental and social governance investors, demonstrating their confidence in Holcim’s financial strength, strategy and ability to deliver our sustainability targets.”

Italy: Buzzi Unicem has signed an agreement with Italgas to collaborate on the development of power to gas plants for implementation in combination with carbon capture systems. Their research will assess the possibility of producing and using synthetic methane obtained from the combination of green hydrogen from power to gas plants with captured CO₂.

Buzzi Unicem’s group technical director at Luigi Buzzi said "We are very interested in the opportunity to collaborate with Italgas as an experienced partner to develop a project that is fully integrated into our industrial investment plan aimed at identifying technologies for capturing and reusing the CO₂ released by our plants, in line with the roadmaps defined by industry associations.” He added “Our aim is to responsibly contribute to containing climate change by developing CO₂ capture technologies and identifying the best solutions for its reuse. We are currently experimenting with calcium looping technology for capturing the carbon dioxide released by the production process at our plant in Vernasca, Piacenza. Thanks to the EU Horizon 2020 Cleanker project, it will be possible to assess the technical and economic sustainability of this technology and estimate the changes to the plant and the investments required to adopt this process in existing cement plants.”

Australia: RMIT University in Melbourne, Victoria, has developed a new method of carbon capture, called the bubble column method. The method uses liquid gallium at 100 – 120°C, through which flue gas is bubbled. This activates the CO₂, leading to oxidation of the metal. The captured carbon accumulates on the surface of the pool.

Gallium is a by-product of bauxite and zinc ores mining. The United States Geological Service (USGS) has estimated its global reserves in these ores alone as 1Mt.

Project co-lead Torben Daeneke said “Turning CO₂ into a solid avoids potential issues of leakage and locks it away securely and indefinitely. Because our process does not use very high temperatures, it would be feasible to power the reaction with renewable energy.” He added “Ideally the carbon we make could be turned into a value-added product, contributing to the circular economy and enabling the carbon capture and storage (CCS) technology to pay for itself over time.”

The Australian Government plans to invest US$719m in low emissions technologies by 2050 under its Net Zero Plan.

India: Dalmia Cement (Bharat) has commenced cement production at its upgraded 2.9Mt/yr Murli cement plant in Maharashtra. The company invested US$125m to install a new fueling system, waste heat recovery (WHR) plant and solar power plant at the facility. It acquired the plant from Murli Industries for US$55.2m in 2020.

The new commissioning brings Dalmia Cement (Bharat)’s total installed capacity to 35.9Mt/yr.

US: LafargeHolcim US has announced the successful transition of two further plants to Portland limestone cement production. The company’s 4.5Mt/yr Ste. Genevieve, Missouri, cement plant and 2.4Mt/yr Alpena, Michigan, plant have begun exclusively producing its OneCem reduced-CO2 Portland limestone cement (PLC).

LafargeHolcim US’ manufacturing North vice president Michael Nixon said "LafargeHolcim is fully engaged in making carbon reduction an urgent priority and 100% dedicated to leading the market transformation needed for climate stability." He added "To achieve net-zero commitments by midcentury, we must start now in accelerating the adoption of low-carbon building solutions to mitigate the impacts of climate change."

LafargeHolcim US successfully transitioned its Midlothian, Texas, cement plant to PLC production in 2021.

Costa Rica: Société Générale de Surveillance has awarded Holcim Costa Rica its Positive Packaging certificate for 100% packaging energy recovery in 2021. The company offset the 1500t carbon footprint of its packaging production for the year by sorting and co-processing 14,000t of paper as fuel. It sourced the paper from its customer cement bag return scheme and through municipal recycling services run by fellow Holcim subsidiary Geocycle Costa Rica.

Holcim Costa Rica sustainability coordinator Catalina Mora said “Waste management is a global challenge, so this project has a direct impact on our contribution as a company to the vision of sustainability for the country.”

China: Hoffmann Green Cement Technologies has secured a Chinese patent for its high performance alkaline activation (H-P2A) geopolymer technology. The patent will enable it to begin to market its clinker-free cement in the country.

Co-founders Julien Blanchard and David Hoffmann said "We are very proud to extend the intellectual property of our H-P2A technology to a market with such great potential as China. The achievement of this first milestone marks our commitment to raising the barriers to entry in as many markets as possible around the world."
