UK: The World Cement Association (WCA) marked the achievement of an ‘historic’ global consensus for decarbonisation at the COP28 climate change conference in the UAE in December 2023 with a new call to global cement producers and suppliers. The association called on all participants in the industry to help promote developments in reduced-CO₂ cement production through enhanced connectivity and communication. It said that technologies like alternative raw materials and alternative fuels (AF), efficiency-enhancing process changes and carbon capture and utilisation (CCU) are widely applied, but unequally, applied in the global cement industry.

Regarding the disparity between different markets, the WCA said “This imbalance underscores the critical need for more research and development funding in emerging markets, where there is real demand for this kind of support as a crucial enabler of progress.” It added “We will join hands with our members and stakeholders to advance the low-carbon and sustainable development of the industry and contribute to building a clean, safe and beautiful world.”

Switzerland/UAE: The COP28 UAE Presidency named École Polytechnique Fédérale de Lausanne (EPFL) among its Energy Transition Changemakers in the Heavy Emitting Sectors category. EPFL won the prize for its LC3 limestone calcined clay cement, which replaces 50% of clinker content with calcined kaolinite clay and limestone. LC3 cement reduces CO₂ emissions by 40% compared to ordinary Portland cement (OPC), and is a readily available solution that can be scaled worldwide. EPFL noted the special importance of LC3 cement for CO₂ reduction efforts in developing countries, and sees it as having the potential to eliminate 500Mt/yr of global CO₂ emissions by 2030. In a post to LinkedIn, the LC3 Project said that nine plants around the world currently produce LC3 cement, with a further 20 planned before 2025.

UAE/UK: The World Cement Association has endorsed new commitments agreed upon by Industrial Deep Decarbonisation Initiative (IDDI) member countries Canada, Germany, the UK and the US at the COP28 climate conference. The commitments include the development of time-bound low CO₂ cement procurement plans. The WCA says that IDDI members’ collective leverage of national purchasing power will help to accelerate the decarbonisation of construction globally.

CEO Ian Riley said “The WCA has always emphasised the need for immediate and collaborative action between government and industry to make carbon-negative concrete a reality at scale. Creating demand for low-emission materials is essential for decarbonisation. Now is the moment to work together to make necessary progress this decade.”

Sinoma International Engineering revealed this week that it has signed a Euro218m contract to supply a new clinker production line for Holcim Belgium. The scope of the deal covers building the new line from limestone unloading via train to clinker transportation and storage. Provisional acceptance and first clinker are stipulated to occur within about four years, by late 2027. Holcim Belgium operates the Obourg Plant, its only integrated unit in the country, and the unit has been preparing to build a new line as part of its Go4Zero project.

Two main points compete for one’s attention with the project at the Obourg Plant. Firstly, this may be the first time a large Europe-based cement producer has publicly contracted a China-based supplier to build a new production line. Secondly, the new line is part of a process to first replace two wet kilns at the site with a dry kiln. This is part of a grand plan at the site to add oxyfuel technology to the plant and then start capturing most of the CO₂ emitted for sequestration in the North Sea.

On the first point, China-based Sinoma International Engineering reported to the Shanghai Stock Exchange in early December 2023 that it had signed a contract for the project. Holcim Belgium has not said that it has appointed the subsidiary of CNBM but this is not unusual. Buyers are at liberty to name suppliers, or not as may be the case. Holcim has been talking about the Go4Zero project for several years though, so appointing a lead contractor is not surprising.

Yet, some cement companies in Europe have previously been circumspect about revealing the use of China-based suppliers. Lafarge France, for example, did not appear to publicly name the involvement of Sinoma International Engineering and its subsidiaries on the construction of a new line at its Martres-Tolosane cement plant between 2019 and 2022, although Lafarge Poland did say in 2020 that it had contracted China Triumph International Engineering for an upgrade to its Małogoszcz cement plant. No doubt there have been other plant projects in Europe from China-based suppliers that Global Cement Weekly is unaware of. It is also worth considering that just because a lead contractor on a plant project is from a particular country it doesn’t mean that the equipment and other sub-contractors necessarily are. And, of course, to add to the confusion, some Europe-based equipment suppliers are owned by companies based in China.

This leads to the second point. Holcim Belgium’s eventual goal is to set up a full-scale carbon capture, transportation and sequestration (CCUS) operation at Obourg using oxyfuel technology by the end of the 2020s. Spending over Euro200m on building a new (but conventional) production line is not trivial but it is being presented as one step towards creating a cement plant for the net zero age. To this end Holcim Belgium has been less shy in naming its partners for the second phase of the project: Air Liquide; Fluxys; and TotalEnergies. This may be due to the collaborative nature of this phase though and the need to apply for European Union (EU) funding to support it. In July 2023 Holcim disclosed that the EU Innovation Fund had allocated grants for three of its projects including the one at Obourg.

For reference, a number of other full-scale oxyfuel projects have been announced in Europe including in Germany at Heidelberg Materials' Geseke cement plant, Holcim Deutschland's Lägerdorf plant in Germany and Schwenk Zement’s Mergelstetten plant. Another one is planned for Heidelberg Materials’ CBR's Antoing cement plant in Belgium. Most of these are planned for the late 2020s or with pilots sooner. The key bit of information to consider here is that adding oxyfuel technology to a cement kiln (or building one with it to start with) makes it easier to capture CO₂ from the flue gas as it is more concentrated. However, the technology is newer and less-tested than many post-combustion carbon capture methods. Hence, the world’s first full-scale CCUS unit at a cement plant, at Brevik in Norway, will use a post combustion method.

All of this begs the question about where the value will lie in building cement plants for the age of net zero? The planned work at Holcim Belgium’s Obourg Plant pretty much summarises this quandary. Building a cement production line is expensive but the cost of disposing of CO₂ may become the single-biggest driver of whether a plant is profitable or not if governments are serious about reaching net zero. To that end today’s announcement from the 2023 United Nations Climate Change Conference (COP28) calling on the parties to “transition away from fossil fuels to reach net zero” is another sign of the increasing effects of the so-called ‘carbon agenda’ upon the cement sector. In which case the companies that can supply equipment to take care of the CO₂ emissions start becoming more important and discussions over who supplies the rest of the kit less so. Naturally, some cement equipment suppliers are already pivoting towards this approach. Others may find different solutions. Whether this works or not is a question for the future. In the mean-time, building new plants is looking increasingly collaborative.

UAE/UK: The Global Cement and Concrete Association (GCCA) has welcomed the first international agreement to transition away from fossil fuels, signed by 200 countries at the COP28 climate conference in Dubai. The GCCA said that the deal recognises the need for deep, rapid and sustained reductions in global CO2 emissions.

GCCA chief executive officer Thomas Guillot said “We welcome the progress made at COP28. Decarbonising global industries such as ours will take the collective effort of governments and industry, finance and policymakers, scientists and civil society, all working together. On behalf of our industry and alongside our members who represent the majority of cement production globally, we participated in the preparation and launch of a number of key initiatives that will help enable the shift to net zero – including the Industrial Transition Accelerator, Cement Breakthrough, and Carbon Management Challenge.” He added “We are fully committed to decarbonising our sector and have a detailed net zero commitment and pathway which we are already working towards, including the substitution of fossil fuels, the use of renewable energy and the deployment of new technologies such as CCUS.”

Germany/UAE: Holcim has claimed two sustainability awards at the COP28 climate conference for its work on the Carbon2Business carbon capture project at its Lägerdorf cement plant in Germany. Holcim won a COP28 Presidency’s Energy Transition Changemaker award and the Outstanding Project award for Germany at the COP28 Mission Innovation Net-Zero Industries Awards. The COP28 Presidency Energy Transition Changemaker initiative fosters deployment of scalable innovations to accelerate decarbonisation. Holcim was among 39 winners across four different industries. Meanwhile, the Mission Innovation Net-Zero Industries Awards are the first global competition in recognition of projects that have revolutionised industries, disrupted the status quo and set new benchmarks for decarbonisation in energy intensive sectors.

Holcim’s chief sustainability officer Nollaig Forrest said “It's great to close COP28 with two awards for our Carbon2business project in Lägerdorf. This is just one of our six carbon capture, storage and utilisation projects in Europe enabling us to produce at least 8Mt/yr of fully net zero cement by 2030.” Forrest added “These awards recognise companies for their collaboration and innovation, and at COP28 Holcim continued to create momentum with our partners across the building value chain to accelerate decarbonisation.”

UAE/UK: The Global Cement and Concrete Association (GCCA) has launched Innovandi Entrepreneur Network. The network will connect low-CO₂ technology developers with GCCA members to work towards the decarbonisation of the global cement sector.

GCCA CEO Thomas Guillot said “Innovation can help unlock our net zero future. We recognise the vital role start-ups play in that transition and very much hope start-ups will join our entrepreneur network. Only by working together and through collaboration will we achieve our shared goals.”

Ryan Gilliam, CEO of US-based alternative cement developer Fortera, said “Thank you to the GCCA for providing a platform that brings like-minded companies together to collaborate on a net zero mission to produce cement. Fortera is honoured to be one of the first companies to join GCCA’s Innovandi Entrepreneur Network, to work in concert with our industry partners to tackle this global initiative.”

UAE/UK: The Global Cement and Concrete Association (GCCA) has welcomed the launch of the Canada/UAE co-led Cement Breakthrough Initiative at the COP28 climate conference in Dubai on 6 December 2023. Prior to the launch of the initiative, the GCCA hosted a roundtable for representatives of the cement industry and governments.

GCCA chief executive officer Thomas Guillot said "We support and welcome the launch of the Cement Breakthrough Initiative. Cement and concrete are essential for so much of our modern world and will also be needed for meeting the challenges ahead. They will play a key role in providing resilient and sustainable infrastructure and safely housing communities around our planet. Our member companies are fully committed to a net zero future – and it will take the combined efforts of industry and government to deliver on this commitment. This is the decade to deliver, and we are delighted to work with the Cement Breakthrough Initiative and the government of Canada to accelerate the transition."

The Global Cement & Concrete Association (GCCA) has been cheerleading at the 2023 United Nations Climate Change Conference (COP28) in Dubai this week with the release of a progress report on the sector’s work towards reaching net zero by 2050. The headline figures are that net CO₂ emissions per tonne of cementitious material fell by 23% in 2021 compared to 1990 based on Getting the Numbers Right (GNR) data. Energy efficiency improved by 19% and the fossil fuel component used by the cement sector has fallen to 80% from 98% in 1990. The GCCA has described 2020 - 2030 as the “decade to make it happen” and has set some targets to back this up. Its members intend to reduce CO₂ emissions per tonne of cement by 20% by 2030 compared to 2020 levels and concrete CO₂ emissions per m3 by 25% over the same time-frame.

The new developments for the cement sector at COP28 so far have been the launch of separate but apparently similar initiatives to help decarbonisation through coordination between nations. The Cement Breakthrough Agenda, backed by the government of Canada and other partners, follows the creation of the Breakthrough Agenda at the 2021 United Nations Climate Change Conference (COP26) whereby designated governments lead so-called ‘Priority Actions’ to decarbonise various sectors. The idea is to collaborate on measures such as policies, regulations and technologies to help reduce the cost of future investment in decarbonisation. The priority actions will be developed in 2023, worked towards in 2024 and then revised on a regular basis thereafter. The German Chancellor Olaf Scholz also launched the so-called ‘Climate Club’ on 1 December 2023 to help developing nations invest in technologies to decarbonise sectors such as cement and steel production. The intention is to set up the technical groundwork for a standardised calculation of CO₂ intensity in selected products, such as cement and steel, set definitions on what net zero is for these sectors and then set up a platform to connect countries with funding and technical support from governments and the private sector. Neither the Cement Breakthrough Agenda nor the Climate Club has mentioned funding though.

Additionally, Holcim announced that it had become a founding member of the Sustainable Markets Initiative’s SMI Circularity Task Force. The group aims to promote the circular economy to the private and public sector. Holcim was keen to point out that it is already recycling nearly 7Mt/yr of construction and demolition waste, with a target of 10Mt/yr pencilled in by 2025.

Other groups are not as upbeat as the GCCA though. The Global Carbon Project, for example, has estimated in its annual Global Carbon Budget that global fossil CO₂ emissions are set to rise by 1.4% year-on-year to 36.8Bnt in 2023. This figure includes both the CO₂ released by cement production and the CO₂ uptake from cement carbonation. Ongoing research by Robbie Andrew, a greenhouse gas emissions scientist at the CICERO Center for Climate Research in Norway and the Global Carbon Project, found that process emissions by the cement sector fell for the first time since 2015 in 2022, to reach 1.61Bnt. This decrease was most likely due to China’s falling cement production in 2022, stemming from a downturn in the local real estate sector. However, both the data from GCCA and the Global Carbon Project may be right simultaneously as they look at the emissions of the cement sector in different ways.

The GCCA’s job is to advocate for the cement and concrete sector and it is presenting itself well at COP28. Since its formation, it has set up roadmaps, encouraged collaboration and innovation, and is now reporting back on its progress. Net zero remains the goal by 2050, but the GCCA is being upfront about the role carbon capture, utilisation and storage (CCUS) is expected to play after 2030 and the lack of any full-scale CCUS units so far. Yet it is tracking what has happened so far through the Green Cement Technology Tracker in conjunction with Leadership Group for Industry Transition (LeadIT).

As for the rest of COP28, various reports have been aired in the international press about whether the conference will call for a formal phase out of fossil fuels in some form or another. Whether it actually happens is another matter entirely, especially considering that the president of COP28 is the chief executive officer of the Abu Dhabi National Oil Company, and any eventual language would likely be vague. Yet the work by the GGCA and others has started to make the unthinkable a little more thinkable.

UAE: Holcim has launched and become a founding member of the SMI Circularity Task Force in collaboration with the Sustainable Markets Initiative (SMI) and others. The SMI Circularity Taskforce aims to accelerate the development of the global circular economy, in complement to Holcim’s goal of recycling 10Mt of construction-demolition materials (CDM) by 2025, and 20Mt in Europe alone by 2030. Holcim and its partners launched the task force at the COP28 climate conference in the UAE on 4 December 2023.

Holcim chair and chief executive officer Jan Jenisch said "With our world’s rising population and urbanisation, we need to build better with less to raise living standards for all while preserving nature. Circularity is a gamechanger to make this happen at scale. At Holcim we are driving circular construction across all metropolitan areas where we operate to build cities from cities, recycling CDM into new building solutions. I am excited to be joining like-minded organisations to accelerate the shift to a more circular future together."
