Austria: The Austrian Cement Industry Association (VÖZ) has launched a roadmap for carbon neutrality by 2050. The initiative follows the 5C approach of Clinker, Cement, Concrete, Construction and Carbonation as prompted by the European Cement Association, Cembureau. Selected targets from the document include reducing the sector’s average clinker factor to 52% by 2040 from 70% in 2020, using carbon-neutral electricity from 2030 and meeting a recycling rate for concrete and demolition waste of 25% in 2050 from 10% in 2022. Sebastian Spaun, the managing director of VÖZ, highlighted the ‘Carbon2ProductAustria’ (C₂PAT) initiative as a key project where capture CO₂ from Lafarge Zementwerke’s Mannersdorf cement plant will be used with hydrogen to produce synthetic fuels, plastics or other chemicals.

Germany: The Ministry for Economy and Climate Protection has presented HeidelbergCement with its German Climate and Environment Innovation Prize (IKU) for its ReConcrete-360° concrete recycling process. The process retrieves hardened cement paste from waste demolition concrete for use in place of limestone in clinker and cement production. The recycled material can also bind CO₂ to act as a carbon sink.

Global research and development Wolfgang Dienemann said “With ReConcrete-360°, we have succeeded in developing a limestone substitute from demolished concrete that also allows us to use the carbon-containing exhaust gases from cement production. A small revolution with a big impact: In Germany alone, the CO₂ savings potential of this process is 10Mt/yr. The IKU award underlines that we can be proud of our pioneering innovation.”

India: Holcim has agreed to sell its Indian business to industry, energy and ports conglomerate Adani Group for US$6.37bn. The assets consist of a 63% stake in Ambuja Cement, which in turn owns 50% of ACC, and a 4.5% direct stake in ACC.

ACC and Ambuja Cement employ 10,700 people and operate 31 cement plants in India. The deal will make Adani Group India’s second-largest cement producer.

Chair Gautam Adani said "With Holcim's global leadership in sustainability, we are acquiring some of the most efficient building materials operations in India, powered with clean technologies like heat recovery systems. We recognise that Ambuja and ACC operations are energy intensive and therefore, when combined with our renewable power generation capabilities, we gain a big head start in the decarbonisation journey that is a must for Indian industry."

Holcim says that its focus is now on expanding its solutions and products business. Reuters News has reported that the group plans to put the proceeds of the assets’ sale towards lower-carbon acquisitions. Its Indian operations contributed 26% of group CO₂ emissions.

Chief executive officer Jan Jenisch said "We will always make cement, but we will decarbonise cement.” He added “We are happy to build up other segments like building solutions and products."

UK: Mannok recorded sales of Euro270m in 2021, up by 16% year-on-year from Euro233m in 2020. The company’s earnings before interest, taxation, depreciation and amortisation (EBITDA) fell by 17% to Euro25.8m from Euro31.1m. The group attributed this to substantial cost absorption beginning in mid-2021. Energy prices rose by 66% year-on-year, while the cost of carbon emissions trading scheme (ETS) credits more than doubled to Euro80/t at the end of the year.

Mannok said that demand for its products remains resilient, supported by stronger cost recovery. It added that a levelling out in energy prices has driven stronger profitability in the first quarter and April of 2022.

Vietnam: ThyssenKrupp Industrial Solutions Vietnam (TISV) and the Vietnam Institute of Building Materials (VIBM) have signed a memorandum of understanding on cooperation between both parties on the research and application of new technologies towards reducing the CO₂ emissions of cement production. At the signing ceremony, Lukas Schoeneck, the chief executive officer of TISV confirmed his commitment to collaborate with VIBM, under the guidance of the Deputy Minister of Construction Nguyen Van Sinh. The parties now plan to identify a lighthouse project that will use alternative fuels in response to an increase in the global price of coal.

Pham Van Bac, Head of the Building Material Division at the Ministry of Construction, said that Vietnam is implementing the a strategy for the development of building materials for the period 2021 - 2030, with a vision to 2050. The plan for the cement industry is to limit the use of natural resources, reduce greenhouse gas emissions and save energy while promoting the maximum use of waste streams from industries and domestic sources as raw materials in cement production.

Germany: Holcim Deutschland says that the preliminary test phase of a new CO₂ separation unit at its Höver cement plant in Lower Saxony has delivered positive results. Plant manager Stephan Hinrichs said that the company was “delighted” with the results so far. In late 2021 Cool Planet Technologies and Hereon signed a memorandum of understanding with Holcim Deutschland to deliver a carbon capture system for a carbon capture and storage (CCS) trial at the plant based on Hereon’s PolyActive membrane technology.

The next stage of the project will start in August 2022 and it will last until late 2024. This will include a one-year active test phase, in which the system is to be examined in long-term operation, planned to start in September 2023. If the results are good enough then the carbon capture unit will be expanded step-by-step so that after the final expansion stage it can separate around 90% of the CO₂ emissions and deliver high-purity CO₂ in liquid form for sequestration or further use. The ultimate aim of the project is to demonstrate performance, economy and operational behaviour on a larger scale in order to check whether the technology can be used at both Höver and other cement plants. Continued funding for the scheme is dependent on an application to the Competence Centre on Climate Change Mitigation in Energy-Intensive Industries (KEI) as part of the Decarbonisation in Industry program.

France: Lhoist and Air Liquide have signed a memorandum of understanding with the aim to build a carbon capture unit at Lhoist’s Réty lime plant in Hauts-de-France. Air Liquide wants to build and operate a unit from 2028 using its Cryocap FG (Flue Gas) technology to capture and purify 95% of the lime plant’s CO₂ emissions. The companies have jointly applied for the European Innovation Fund large scale support scheme to pay for the project. This partnership is a step towards the creation of a low-carbon industrial ecosystem in the Dunkirk area.

Lhoist’s ‘Chaux et Dolomies du Boulonnais’ plant in Réty is France’s largest lime production plant. A potential carbon capture unit at the plant could potentially reduce the CO₂ emissions of the plant by more than 600,000t/yr. Captured CO₂ would then be transported to a multimodal CO₂ export hub in Dunkirk, currently under development, and sent to be sequestered in the North Sea as part of the D’Artagnan project, which has received the PCI (Project of Common Interest) label from the European Commission. The implementation of the project will be possible as public funding from European and/or French schemes supporting decarbonisation become available.

Mexico: Cemex has expanded its Executive Variable Compensation program, which includes progress on its carbon reduction goals as a variable, to cover over 4500 executives. The initiative is part of the company's Future in Action program, which focuses on reducing the carbon footprint of Cemex's operations and products to become a net-zero CO2 company by 2050. From the start of 2022, the CO₂ emissions component will have an impact that will range from -10% to +10% in the total cash payout of the annual executive variable compensation.

World: The Global Cement and Concrete Association (GCCA) has named its first six startups to receive backing under the inaugural Innovandi Open Challenge. The startups have partnered with GCCA members to help increase cement’s sustainability towards achieving net zero CO₂ concrete production by 2050. This will lead to the formation of six consortia to further test, develop and deploy their new technologies.

Carbon capture, utilisation and storage (CCUS) startups CarbonOrO, MOF Technologies and Saipem, all based in Europe, are among the participants. GCCA members are currently involved in dozens of pilot projects and aim to have 10 industrial-scale carbon capture plants installed by 2030. Other startups Carbon Upcycling Technologies and Fortera, from Canada and the US respectively, use captured CO₂ to produce low-carbon cement and cementitious materials, while UK-based Coomtech has developed a low-cost drying technology using turbulent air.

GCCA CEO Thomas Guillot said “It’s a proud moment to see the industry coming together to support such innovative start-ups on their journey. Our member companies were greatly impressed by their ambition to be a key part of the climate solution. The programme is another big step forward towards unlocking innovation to help us achieve our net zero goal.” He continued “As the need for resilient and sustainable communities to support a growing global population becomes more pressing , cement and concrete will be essential to providing the infrastructure and buildings that society needs. Achieving net zero concrete relies on a number of different groups playing their part, and as an industry we’re looking outwards as well as inwards, to see how start-ups like these can support our goals.”

Mexico: Cemex intends for its Vertua products to account for over half of all of its cement and concrete sales by 2025. The Vertua range was launched in 2020 and its cement and concrete products accounted for 34% and 31% of total sales respectively in the first quarter of 2022. Vertua products have a CO₂ reduction of at least 25% compared to traditional cements. For concrete the CO₂ reduction ranges from 30% up to a full net-zero option.

References for Vertua concrete include La Marseillaise, a skyscraper in Marseille, the HS2 high-speed railway in London, the Querétaro-Irapuato highway in Mexico, the San Diego State University stadium in California and the Pereira shopping centre in Colombia. Vertua cement and concrete products have been launched in Colombia, Croatia, the Czech Republic, the Dominican Republic, Egypt, France, Germany, Guatemala, Mexico, Panama, the Philippines, Poland, Puerto Rico, Spain, the US, the UK and the UAE.
