Sweden: Swedish cement manufacturer Cemvision has entered a strategic partnership with Norway-based residential developer JM to develop ‘climate-friendly’ cement and concrete. As part of the agreement, JM has also acquired a minority stake in Cemvision.

Cemvision’s cement reportedly reduces CO₂ emissions by up to 95% compared to traditional cement, through the use of recycled industrial waste from mining and steel industries, combined with renewable energy in its kiln operations.

Europe: Sweden-based SaltX has signed a letter of intent with German engineering firm thyssenkrupp Polysius to collaborate on establishing 100% electric cement production facilities in Europe. The facilities will combine SaltX’s electric arc calciner (EAC) technology with thyssenkrupp Polysius’ material handling solutions.

CEO of SaltX Lina Jorheden said "Strong partnerships are essential for us to effectively implement our technology and reduce millions of tonnes of CO₂ emissions from the industrial sector. Our collaboration with thyssenkrupp Polysius is crucial for developing complementary systems to the EAC technology and building electrified facilities for our customers."

Sweden: Heidelberg Materials has successfully operated a 300kW plasma-heated cement kiln at its Slite cement plant, which it claims is the first of its kind. The producer has achieved 54 hours of continuous operation, with 60% CO₂ concentration in the flue gas. The aim is to reach 99%.

The kiln is part of the ELECTRA project, which aims to replace traditional combustion processes with electricity-based solutions, like plasma. The project consists of 17 partners from 8 countries.

Project manager Bodil Wilhelmsson said "It looks very promising. We started the tests at the end of last year and can now say with certainty that this is the right way to go: we will be able to produce clinker with plasma."

Fuel-related CO₂ emissions from cement production are eliminated because no fuel needs to be used in the production process. Instead, CO₂ is heated to over 5000°C, where it becomes a plasma jet that heats the material in the kiln.

Wilhelmsson added "The absence of fuel in the process means that there is no ash in the product. This means that a parameter that could affect the quality of the product if it fluctuates is no longer considered. So, it looks like the quality of the clinker can actually be slightly higher in this process."

Heidelberg Materials plans to build a 1MW kiln in Skövde cement plant in 2026, where further tests will continue.

Sweden: Bruks Siwertell has received an order for a 10 000 S mobile ship unloader for an undisclosed client. The customer owner will use the unloader as part of a rental ship unloading service, operating across multiple port locations. The order is scheduled for commissioning in spring 2025. It will be delivered fully assembled ready for operation. Jörgen Ojeda, Sales Director, Mobile Unloaders, Bruks Siwertell added that the client had previously used an Siwertell 15 000 S mobile ship unloader for nearly two decades.

Sweden: NovaAlgoma Cement Carriers has placed an order for Climeon’s organic rankine cycle (ORC) waste heat recovery technology, HeatPower 300, to be installed on a new methanol dual-fuel cement carrier. The HeatPower 300 unit will generate up to 300kW of electricity on board the carrier by harnessing residual heat from the engine cooling water and exhaust gases to reduce fuel consumption and emissions.

Sweden: SaltX Technology has secured a new grant from the Swedish Energy Agency for its project ‘Demonstration of new electric kiln technology at industrial scale to enable emission-free cement production.’ This funding follows previous support for testing and optimising electric quicklime production at its test and research facility in Hofors, Sweden. The grant aims to adapt and test SaltX's technology specifically for cement production, awarded under the pilot and demonstration program. It constitutes partial funding for the work that is planned to begin in March 2025 at the company's test and research facility.

Acting CEO of SaltX, Lina Jorheden, said "It is very encouraging that the Swedish Energy Agency supports us in our work to commercialise SaltX's electrification technology for the cement industry. The grant is an important component in the upcoming industrialisation phase."

Sweden: Heidelberg Materials' Slite CCS project in Gotland has received new funding. The Just Transition Fund has provided approximately €6.1m to support project preparation from 2024 to 2026, aiming for operational readiness by 2030. The project targets the creation of a fully decarbonised plant with the capacity to capture 1.8Mt/yr of CO₂, potentially reducing Sweden's total emissions by 4%.

Sweden: Peab has entered a product delivery agreement with Stockholm-based start-up CemVision, starting from 14 May 2024. CemVision has developed a cement that reportedly reduces CO₂ emissions by over 95% compared to traditional cement, by replacing limestone and fossil fuels with refined industrial waste and renewable energy. Over the next few years, Peab will use CemVision's ultra-low carbon cement for various projects, including infrastructure, water treatment, foundation work and prefabricated concrete.

Oscar Hållén, CEO of CemVision, said “We are thrilled to be able to deliver our product to Peab. We see that green cement has become crucial for entire industries to be able to meet their climate commitments. The demand is already enormous and all forecasts indicate that it will only increase.”

Sweden: Researchers at Chalmers University of Technology, Sweden, have developed a method to simplify the construction of textile-reinforced concrete structures, a move that is expected to lead to more environmentally friendly infrastructure like bridges, tunnels, and buildings. The new technique addresses the high carbon footprint of cement.

This innovation, involving carbon fibre textiles as a replacement for steel reinforcement, enables lighter structures with reduced cement usage, thereby lowering the overall carbon impact. Karin Lundgren, Professor of Concrete Structures at Chalmers Department of Architecture said "A great deal of the concrete we use today has the function to act as a protective layer to prevent the steel reinforcement from corroding. If we can use textile reinforcement instead, we can reduce cement consumption and also use less concrete, thus reducing the climate impact."

The research is detailed in a paper titled 'Textile reinforced concrete members subjected to tension, bending, and in-plane loads: Experimental study and numerical analyses', which was published in the Construction and Building Materials journal. The study, a collaborative effort between Chalmers University and Gdansk University of Technology in Poland, is supported by the Swedish Research Council.

Sweden: Umeå University is part of the ELECTRA project, a €20m EU initiative aimed at advancing green transition in cement and lime production through electrified processes. This project, involving global industry leaders, is funded under the Horizon Europe initiative and led by VTT Technical Research Centre of Finland.

The Department of Applied Physics and Electronics at Umeå University has collaborated with the Swedish quicklime and cement industry since 2007. Matias Eriksson, director of the Centre for Sustainable Cement and Quicklime Production at Umeå University, said “This is an important project. It is the first Horizon Europe project we are participating in," He continued "We are pleased with the confidence the European Commission, heavy materials industry and other research performers show in our work. ELECTRA can play an important role in the industry's green transition, first and foremost in Sweden and the rest of Europe. But because the technology and the industry are global, the effects can be extensive."
