Sweden: The government has extended Cementa’s permit to continue mining limestone at the quarries supporting its Slite cement plant for just over one year until the end of December 2022. The cement producer said that it would restart its mining activity immediately. However, it warned that the decision could still be appealed and work stopped whilst the case was pending. The subsidiary of Germany-based HeidelbergCement also refused to rule out shortages of cement in the future due to general uncertainty with the situation. Cementa has now started applying for a three to four year mining permit at the site.

Sweden: Cementa says it is preparing to ration deliveries of cement in December 2021 due to uncertainty about whether it can renew the mining licence at its integrated Slite plant in Gotland beyond the end of October 2021. The subsidiary of Germany-based HeidelbergCement has warned customers that it is preparing to implement quotas of cement products from its two plants and five terminals on a week-by-week basis. The quotas will be based on what level of cement customers have ordered previously over the past 36 months. It will also take into account whether there have been significant volume changes during the period.

Cementa says it submitted its application for an emergency permit in late September 2021. It needs approval from the government by mid-November 2021 to avoid a potential cement shortage. However, any such approval may be subject to an appeal leading to further delays in mining.

Sweden: Cementa has announced that its Stockholm cement terminal will no longer receive deliveries of its Slite brand cement and will instead begin solely stocking the company’s fly ash cement from 1 December 2021. The producer says that the transition will reduce the carbon footprint of the terminal’s products by 30,000t/yr. Slite cement will continue to be available from the nearby Köping and Oxelösund cement terminals.

It’s been a good week for carbon capture in cement production with new projects announced in France and Poland.

The first one is a carbon capture and utilisation (CCU) collaboration between Vicat and Hynamics, a subsidiary of energy-provider Groupe EDF. The Hynovi project will see an integrated unit for capturing CO₂ and producing methanol installed at Vicat’s Montalieu-Vercieu cement plant in 2025. It aims to capture 40% of the CO₂ from the kiln exhaust stack at the plant by using an oxy-fuel method and installing a 330MW electrolyser to split water into oxygen and hydrogen for different parts of the process. The CO₂ will then be combined with hydrogen to produce methanol with potential markets in transport, chemicals and construction. The setup is planning to manufacture over 0.2Mt/yr of methanol or about a quarter of France’s national requirement. The project was put forward under a call for proposals by the Important Projects of Common European Interest (IPCEI) program. Pre-notification of its participation in the program has been received from the French government and it is currently being evaluated by the European Commission. Vicat’s decision to choose its Montalieu-Vercieu plant for this project is also interesting since it started using a CO₂ntainer system supplied by UK-based Carbon8 Systems there on an industrial scale in November 2020. This system uses captured CO₂ from the plant’s flue gas emissions to carbonate cement-plant dust and produce aggregate.

The second new project is a pilot carbon capture and storage (CCS) pilot by HeidelbergCement at its Górażdże cement plant in Poland. This project is part of the wider Project ACCSESS, a consortium led by Sintef Energi in Norway that aims to cut carbon capture, utilisation and storage (CCUS) costs and to link CO₂-emitters from mainland Europe to storage fields in the North Sea. The cement plant part in Poland will test an enzyme-based capture method using waste heat at the plant. Another part of the project will look at how the captured CO₂ can then be transported to the Northern Lights storage facility in Norway including the regulatory aspects of cross-border CO₂ transport. ACCSESS started in May 2021 and is scheduled to end in April 2025. It has a budget of around Euro18m with Euro15m contributed by the European Union (EU) Horizon 2020 fund.

HeidelbergCement also says that the second stage of its LEILAC (Low Emissions Intensity Lime And Cement) project at the Hannover cement plant is part of ACCSESS, with both testing of the larger-scale Calix technology to capture CO₂ and the connected transport logistics and bureaucracy to actually get it to below the North Sea. That last point about Calix is timely given that US-based Carbon Direct purchased a 7% stake in Calix in mid-September 2021 for around US$18m. Whilst on the topic of carbon capture and HeidelbergCement don’t forget that the group’s first full-scale carbon capture unit at Norcem’s Brevik cement plant, using Aker Solution’s amine solvent capture technology, is scheduled for commissioning in September 2024. Another carbon capture unit is planned for Cementa’s Slite plant in 2030 but the proposed capture method has not been announced.

Other recent developments in carbon capture at cement plants include Aalborg Portland Cement’s plan to capture and store CO₂ as part of the Project Greensand consortium. The overall plan here is to explore the technical and commercial feasibility of sequestering CO₂ in depleted oil and gas reservoirs in the Danish North Sea, starting with the Nini West Field. The project is still securing funding though, with an Energy Technology Development and Demonstration Program application to the Danish government pending. However, the Danish Parliament decided in December 2021 to set aside a special funding pool to support a CO₂ storage pilot project so this initiative seems to be making progress. If the application is successful, the consortium wants to start work by the end 2021 and then proceed with an offshore injection pilot from late 2022. How and when Aalborg Portland Cement fits in is mostly unknown but a 0.45Mt/yr capture unit at its Rørdal cement plant is tentatively planned for 2027. There’s also no information on the capture method although Aker Carbon Capture is also part of the Project Greensand consortium. Finally, also in September 2021, Chart Industries subsidiary Sustainable Energy Solutions announced that it had selected FLSmidth to help adapt and commercialise its Cryogenic Carbon Capture carbon capture and storage (CCS) system for the global cement industry.

All of this tells the cynics in the audience that a large international climate change meeting is coming up very soon. Most cement companies will likely want some good news to show off when the 2021 United Nations Climate Change Conference (COP26) dominates the media agenda in November 2021. Other observations to point out include that none of the projects above are full-scale industrial carbon capture installations, most of them are consortiums of one sort of another and that they are all subsidised or want to be. While hydrogen and CO₂ networks get built this seems inevitable. Yet, we’re not at the stage where cement companies just order carbon capture units from a supplier, like they might a new clinker cooler or silo, without the need for long lists of partners. When this changes then carbon capture looks set to flourish.

On a final note, the UK is currently experiencing a shortage of commercially-used CO₂. The reasons for this have nothing to do with the cement industry. Yet consider the constant doom-and-gloom about record global CO₂ emissions and the sheer amount of effort going into reducing this by the projects mentioned above and others. Life has a sense of humour at times.

Sweden: Cementa plans to restrict its exports to the Baltic countries and Denmark. Finwire News has reported that the subsidiary of Germany-based HeidelbergCement is enacting the measure in order to focus its cement supply on its Swedish customers.

Cementa’s prospects for continued mining limestone in Sweden beyond the end of October 2021 have been looking dubious recently. The subsidiary of Germany-based HeidelbergCement wants to carry on mining limestone at its quarries near its integrated Slite plant in Gotland after 31 October 2021 when its current permits expire. However, the Supreme Land and Environmental Court rejected its renewal application in July 2021 on the grounds that the impact of the quarries on groundwater had not been sufficiently investigated. Then the Supreme Court ruled that it had no basis for appeal at the end of August 2021. This leaves the cement producer hanging on for proposed government plans to make legislative changes to keep limestone mining ongoing for another eight months until mid-2022 and then for whatever scheme the legislators cook up next.

In July 2021 construction multinational Skanska publicly said that it was taking the situation ‘seriously’ because its concrete suppliers had warned it of the impending risk that they would potentially be unable to meet demand in the third quarter of 2022. At the same time the Swedish Construction Federation and related bodies noted that up to 175,000 jobs in construction could be adversely affected with a loss of investment of nearly Euro2bn/month due to the predicted cement shortage. In their view, increasing imports in the short term was unrealistic due to capacity constraints at ports and import terminals. Understandably, the Swedish government has been scrambling to keep the quarries open to protect cement supply and has been accused by both the local press and environmental bodies of circumventing legal norms in the process.

This is not a good situation to be in for either Cementa or anyone who might want to use cement locally in the near future. The cement producer operates both of Sweden’s integrated plants, at Slite and Skövde respectively, with Slite holding around 80% of the company’s production capacity. On its own, the Slite plant alone supplies 75% of the country’s cement, with about another 10 – 15% provided by importer Schwenk Zement. As a whole Cembureau data shows that the country’s market was just under 3Mt/yr in 2020 and stable despite the coronavirus pandemic. A small decline in the residential segment was reported, coupled with a ‘flat’ infrastructure segment, although increased demand from wind farm construction was noted. Cementa stopped production at a third local integrated plant, Degerhamn, in mid-2019 due to low profitability at the site and tightening environmental regulations.

Cementa and HeidelbergCement are putting up a fight by publishing lots of information on Cementa’s website about the permit application process and working towards both solutions in the short and longer term. In early September 2021 Nordkalk signed a deal with Cementa to supply it with limestone. However, as Thomas Lind, the head of cement for HeidelbergCement Northern Europe, pointed out in August 2021, the agreement won’t cover the entire shortfall, nor would it be ideal from logistical or environmental angles. On the opposing side, the Swedish Society for Nature Conservation has joined with the Supreme Land and Environmental Court in opposing the quarry permit renewal along with other environmental groups. Plus the government decision to force through a permit reprieve has also given ammunition to its political rivals.

The argument over Slite’s quarry sums up some of the challenges facing society over continued cement production in a world with ever-tougher environmental legislation. Cement plants are likely to face mounting opposition on environmental grounds but most governments will panic when facing the potential consequences of societies running out of essential building materials. There are many ways to avoid this scenario, such as far greater community and political involvement on the part of cement companies, recognition by governments of the importance of building materials, supporting the development and uptake of concrete made with less Ordinary Portland Cement or switching to higher ratios of other building materials and so on. Yet, without preparation, legislators elsewhere will also find themselves in similar positions to the one the Swedish government is in now.

Slite’s problems have arisen in part over a perceived direct threat to local drinking water, although Cementa says that this is absolutely not the case. Typically, cement plants in similar battles find themselves in opposition to local communities due to the immediate impacts of quarrying or production on water, or due to noise or dust. Yet the hidden consequence of clinker production is significant process CO₂ emissions with resulting global climate change. The particular tragedy in Gotland is that HeidelbergCement is one of the more sustainable-minded cement companies, with investment to match. In June 2021 it announced ambitions to upgrade the Slite plant to become the world’s first carbon-neutral cement plant through bio-based fuel substitution and a carbon capture and storage unit by 2030. This may be eight years away but it is one of very few full scale cement plant carbon capture upgrades that have been promised worldwide.

Sweden: Cementa has said that it ‘views positively’ the Swedish government's rapid action in proposing a new bill on limestone mining licencing. It lobbied the government to stick to its schedule to have a temporary licence in place for Cementa’s use of its quarries in Gotland by 31 October 2021. The group said that it is working ‘with full force’ to find practical and legal solutions to secure the Swedish cement supply in the short and long term.

Sustainability manager Karin Comstedt-Webb said “It will be important that the time frames are not limited by the new bill, but that it enables flexibility to secure Swedish cement supply in the future, so that we avoid ending up in the same problematic situation again in just a number of months.” She added “I want to emphasise that Cementa in all situations works with high environmental requirements. Our ambition remains to be able to show that our industrial operations and the production of the building material cement can go hand in hand with protection of Gotland's nature, water and people.”

Sweden: Cementa will not be able to appeal a land and environmental court’s ruling preventing it from using its quarries on the island of Gotland. The Swedish supreme court has ruled that the subsidiary of Germany-based HeidelbergCement has no basis for appeal. Its previous application to extend mining activities at the sites until 2041 failed due to shortcomings in its environmental impact assessments. The quarries supply cement production at the company’s Slite cement plant in Gotland.

Sweden: Cementa says that the decision by the Supreme Land and Environmental Court to reject its renewal application to continue mining limestone at its quarries in Gotland will create a ‘crisis’ for consumers in the autumn of 2021. The quarries supply its integrated Slite cement plant. The producer said that the ‘majority’ of Swedish cement production could cease in November 2021 following the expiry of the current licence in October 2021.

“We are seriously concerned but also surprised by the court's ruling today,” said Magnus Ohlsson, the chief executive officer of Cementa. “Limestone has been mined in Slite for over 100 years, which has built up a huge knowledge bank about how the business affects the surrounding environment. Our application is solid and clearly shows that it is possible to conduct a continued sustainable limestone mining in the area. We must go through the decision carefully and then set up the strategy for how we will handle the situation,” He added, “For Sweden, our customers and for us and our employees, it is important that political decision-makers and authorities quickly draw up new guidelines for how the supply of critical building materials such as cement and concrete should work.”

The subsidiary of Germany-based HeidebergCement originally received clearance in 2020 to renew its mining operations at the site until 2041. However, this was subsequently challenged. The current decision by the Supreme Land and Environmental Court was reached as they said they had insufficient evidence to assess the environmental impact of the application.

Sweden: Germany-based HeidelbergCement subsidiary Cementa plans to upgrade its Slite unit in Gotland to become the world’s first carbon-neutral cement plant. This will be achieved through modification of the plant’s fuel system to ‘significantly raise’ biobased fuel substitution, as well as 100% carbon capture and storage (CCS) via a 1.8Mt/yr CCS installation. Full-scale capturing of the plant’s CO₂ emissions is scheduled by 2030.

Chair Dominik von Achten said, “HeidelbergCement will be the leader in the global cement industry on its transformation path towards climate neutrality. The key for decarbonising our industry is to find, apply and scale technical solutions for carbon capture and utilisation or storage (CCU/S). After having gained valuable experience with CCU/S technologies in Norway and other countries, we are now excited to make the next step with a completely carbon-neutral cement plant in Sweden.”
