South/Central America: Holcim Latinoamérica says that it expects to use 18% renewable power across its operations in February 2023, compared to 8% throughout 2022. The regional unit of Holcim says that it will increase its share of renewable power to 25% by the end of 2023. It is committed to a target of 60% renewables by 2030. Holcim Latinoamérica's operations span Argentina, Colombia, Costa Rica, Ecuador, El Salvador, Nicaragua and Mexico.

Earlier in February 2023, Holcim Nicaragua commenced construction of a 3.38MW solar power plant in Nagarote, León Department. The producer said that the solar power plant's contribution to the national grid will cover 40% of its consumption in its cement operations there.

Holcim's Latin America regional head Oliver Osswald said “Our world is in constant change from population growth, urbanisation and the climate challenge. That is why, at Holcim, we are determined to put our best foot forward to accelerate low carbon circular construction."

Congratulations to Lafarge France for launching the first calcined clay cement unit in Europe. The subsidiary of Holcim says that the unit, based at the integrated Saint-Pierre-la-Cour cement plant, is the first of its kind on the continent. It is using the company’s proprietary proximA Tech technology and will produce up to 500,000t/yr of cement in its ECOPlanet range. The operation is also powered with biomass alternative fuels and uses a waste recovery system to further drive down overall CO₂ emissions. Once production ramps-up the producer expects that 30% of cement from the Saint-Pierre-la-Cour plant will be from the ECOPlanet range by 2024.

The investment at Saint-Pierre-la-Cour was Euro40m. Holcim is also producing calcined clay cement at its La Malle plant in France. It received an investment of Euro6m in 2022 to produce low-carbon cements. Together, both plants are aiming to produce over 2Mt/yr of calcined clay cement by 2024. As is usual for these kinds of projects, the French government partly funded the clay calcination unit at Saint-Pierre-la-Cour as part of the ‘France Relance’ scheme investing in large-scale decarbonisation and energy efficiency initiatives.

Calcined clay cements in Europe aren’t exactly new, but Holcim’s new unit in France does appear to be the first full-scale line located at a cement plant. Research by OneStone Consulting, for example, reckons that the first flash activated clay unit expressly set up to supply the cement sector was commissioned in 1995 in Toulouse, France. More recently, Hoffmann Green Cement inaugurated its 50,000t/yr pilot plant at Bournezeau in France in 2018. This site produces cements made from flash calcined clay and blast furnace slag, although it is unclear how demand for the different products varies. A new 0.25Mt/yr plant in the Vendée department was scheduled for commissioning in the second half of 2022. Another 0.25Mt/yr plant in Dunkirk is expected to be commissioned in the second half of 2024.

Cementir Group launched its calcined clay cement product FUTURECEM in Denmark in 2021 with production via a pilot plant. It then extended this to the Benelux and French cement markets in 2022. As part of its industrial plan for 2021 - 2023 it was planning to build a clay calcination unit to support the growth of FutureCem. FLSmidth revealed in June 2021 that it had won a contract to build a 400t/day clay calcination unit for Vicat’s Xeuilley integrated cement plant. The deal was worth around Euro27m and commissioning is scheduled for 2023.

Firstly, it is interesting to see a focus on France for some of the projects above. The presence of Lafarge’s technical centre in Lyon may explain the interest for that company. However, Hoffmann Green Cement and Vicat are also active in the field. It is worth noting that France also holds a busy secondary cementitious material market with standalone operators including Ecocem, Cem’In’Eu and Hoffmann Green Cement. Secondly, despite the early start, clay calcination for cement is currently more active outside of Europe. In Africa, for example, there is at least one live full production line and a number of other projects on the way. Various other pilots and projects are also happening elsewhere around the world, often in conjunction with the limestone calcined clay cement (LC3) initiative. Where calcined clay cement production in Europe goes from here is uncertain at present as it is one solution among many for lower carbon cement products in the future. Yet, the projects that have made it so far to the commercial scale will be watched closely by the companies that have invested in them - and their competitors.

Austria: RHI Magnesita has invested in Australia-based MCi Carbon as part of a long-term strategic cooperation agreement to research and develop technologies to decarbonise the production of refractories. MCi Carbon sells a mineral carbonation process that creates a range of low-carbon embodied materials, including calcium and magnesium carbonate by carbonating minerals in by-products of industrial processes. RHI Magnesita intends to use this process to reduce its Scope 1 emissions from mineral processing during its refractory production process.

Stefan Borgas, the chief executive officer of RHI Magnesita, said "This partnership could become a breakthrough towards decarbonising the industry. It fits seamlessly with RHI Magnesita's ambitious sustainability strategy." He added "We still have a long way to go but our early-stage investment and the clear intention of a long-term collaboration make this day so memorable. Together with the like-minded team from MCi we will pave the way for a greener industry."

So far, both companies have worked together on CO₂ mitigation studies, mineral carbonisation feedstock assessments and techno-economic analyses at RHI Magnesita's sites around the world. In a next step, the companies' joint efforts will focus on industrial scale-up, expected to start in 2024 with the set-up of a demonstration plant by MCi at Newcastle in Australia, supported by the Australian government.

Greece: Titan Cement has acquired a share in Aegean Perlites. The company operates perlite and pozzolan quarries on the island of Yali. It also has access to port facilities. Titan Group says it is making the investment to gain direct access to pozzolan reserves to increase its volume of pozzolan-based cementitious products with a lower clinker factor. The deal is connected to Titan’s target to reduce its CO₂ emissions by 35% by 2030, compared to 1990 levels, and increase the share of green products in its portfolio to over 50%.

Yanni Paniaras, the Group Executive Director Europe of Titan, said “We are pleased to partner with the Govdelas family as joint shareholders in Aegean Perlites, building on our excellent long-term collaboration and aiming to grow our business, maximising the high potential of the Yali pozzolans.”

Belgium: Cembureau, the European cement association, has warned against a proposed 2041 phase-out date for industrial CO₂ in the Commission draft Delegated Act on renewable fuels of non-biological origin (RFNBOs). The European Commission’s (EC) draft Delegated Act on the greenhouse gas saving criteria for RFNBOs sets the rules under which such fuels can qualify as sustainable. The European Commission considers that CO₂ from industrial sources should not be allowed for the production of synthetic fuels as of 2041, as this would go against the objective of carbon neutrality by 2050.

Koen Coppenholle, the chief executive officer of Cembureau, said “By proposing an arbitrary deadline on the use of industrial CO₂, the EC severely restricts the deployment of carbon capture and utilisation (CCU) in the cement sector.” He continued “We regret that this phase-out date was established without a thorough impact assessment. This risks negatively impacting several on-going carbon capture projects in the European Union (EU), at a time of a global race for green investments.” Coppenholle also called for a “real, thorough debate on CO₂ utilisation” to ensure that EU policies support CCU and the deployment of CO₂ transport infrastructure and storage.

The association is objecting against this proposal because in its view: manufacturing synthetic fuels using industrial CO₂ make a “decisive” contribution to climate mitigation in the short to medium term; no impact assessment has been presented by the EC; the delegated act threatens the viability of existing CCU projects in the cement sector, which require a payback time of 30 - 35 years; and the Delegated Act does not recognise the reality of industrial installations like cement plants, which are faced with unavoidable CO₂ emissions, and may not have access to CO₂ geological storage sites.

The Delegated Act will be passed to the European Parliament and Council for further scrutiny until April 2023 whereupon they will either accept to reject the proposals. The scrutiny period can be extended to June 2023 at the request of either body.

UK: Carbon Re and A³&Co have signed a strategic partnership agreement to sell cement producers products to optimise production processes to reduce operational costs and carbon emissions. Carbon Re says that its Delta Zero industrial decarbonisation software product can cut fuel use by up to 10% and CO₂ emissions by up to 20% and has been piloted in cement plants in three continents. The product uses a machine learning approach to model a cement plant’s production environment and optimise processes for low CO₂ output and fuel use with no capital expenditure. A³&Co is a strategic and technical consulting company that is focused on the cement sector.

Sherif Elsayed-Ali, the chief executive officer and co-founder of Carbon Re, said "Our technology is already having a huge impact on some of the world's most energy-intensive industries. This strategic partnership with A³&Co will enable even more cement producers to benefit from the operational savings offered by AI as they tackle the challenge of cutting carbon emissions and rising fuel prices."

US: The Department of Energy’s (DOE) Carbon Storage Assurance Facility Enterprise (CarbonSAFE) initiative has awarded funding of US$8.9m to Heidelberg Materials North America to study the subsurface geology for suitability for the storage of carbon dioxide at the Mitchell integrated cement plant in Indiana. The proposed project will geologically characterise several prospective reservoirs under the Mitchell plant for storage of more than 50Mt of CO₂ over a 30-year timeframe.

The award, which is managed by the National Energy Technology Laboratory, will be issued to the Illinois State Geological Survey at the University of Illinois (ISGS) as the prime contractor, with the company acting as a technical and industrial partner. Heidelberg Materials is contributing about US$1.5m in funding while ISGS will be contributing approximately US$0.6m for a project total of US$11.1m. The funding was part of a DOE initiative that generated nearly US$125m in funding for 10 projects to characterise suitability for carbon storage across the US.

Heidelberg Materials’ Mitchell cement plant is being upgraded with a new production line. Full production on the new line is anticipated to start in early 2023.

Mexico: GCC has secured validation by the Science-Based Targets Initiative (SBTI) for its latest CO₂ reduction goals. The group has committed to reducing its Scope 1 emissions per tonne of cementitious product by 31% and its Scope 2 emissions per tonne of cementitious product by 57% between 2015 and 2030. It has also committed to a 37.5% absolute reduction in its products’ Scope 3 emissions over the same period. The goals will serve as sustainability performance targets for GCC’s US$500m sustainability-linked bond, which it issued in January 2022.

GCC's vice president of sustainability and environment Gina Lotito said "We are proud and excited to be a catalyst of progress towards a low-carbon future. Our laser-focus on our climate change strategy and emphasis on reducing CO₂ emissions is a testament to our commitment to creating a sustainable future. While we celebrate our achievements, we acknowledge that there is still much work to be done and remain steadfast in our mission."

Europe: The European cement association, Cembureau, has 'welcomed the objectives' of the European Commission's new Green Deal industrial plan. The Green Deal attempts to create a predictable and simplified regulatory environment in which to scale up the production and implementation of net-zero CO₂ technologies.

Cembureau also issued its advise for a successful Green Deal implementation. The association said that the framework must match the US Inflation Reduction Act in its provision of tax rebates and other incentives. It said that the plan must establish stable renewable energy prices and rapid permit procedures, with a focus on deployment of renewables at industrial sites. It also called for funding under the plan to finance the development of infrastructure for CO₂ transport and storage.

Japan: Mitsubishi Heavy Industries (MHI) has won an Award for Excellence at the 41st Nikkei Excellent Products and Services Awards for its carbon capture system. It was among eight industrial products to win the award for the year. The panel of judges selected MHI's system for its compact and versatile module configuration, which shortens installation and transport times.

MHI's model has been in industrial operation since June 2022, when MHI inaugurated its first system at Taihei Dengyo Kaisha's Seifu Shinto biomass power plant. The technology is now in operation or under implementation at cement plants in Japan and overseas. Most recently, MHI secured a carbon capture contract with a UK cement plant, Hanson's Padeswood plant, in mid-December 2022.
