France: Heidelberg Materials has announced plans for its CIRCO₂BETON concrete recycling project. It intends to build an industrial-scale selective separation unit at its Achères quarry near Paris. Here it will recycle demolished concrete by crushing it and separating it into its components: sand, aggregates, and recycled concrete paste (RCP). The recycled sand and aggregates will be reincorporated into new concrete.
The RCP will be transported to the Ranville cement plant in the Normandy region. There, a reactor for enforced carbonation will be installed to carbonate the RCP by exposing it to CO₂-containing exhaust gases from the kiln. The carbonated RCP acts as a carbon sink and will replace clinker in new low-carbon cement types. The project has the potential to reduce the CO₂ emissions of the Ranville cement plant by 20%.
CIRCO₂BETON is supported by the ‘Investment for the Future’ Program coordinated by the Ecological Transition Agency (ADEME). In addition, the Île-de-France region supports the selective separation plant at Achères through its zero-waste and circular economy plan. Subject to the funding, construction of both industrial pilots is scheduled to start in 2024 with production of RCP starting in 2025. The carbonation reactor is planned to be operational by 2026.
Nicola Kimm, the chief sustainability officer at Heidelberg Materials, said ”We are investing in a pioneering large-scale project based on innovative process technologies. Selective separation and CO₂ mineralisation are important levers to reduce the carbon footprint of our products. By closing the materials loop, we prove that concrete has the potential to be the most sustainable building product over its entire life cycle from production to recycling.”

Pakistan: Cement producers despatched 44.6Mt of cement during the 2023 financial year, down by 16% year-on-year from 52.9Mt in the previous financial year. Exports dropped by 13% to 4.57Mt from 5.26Mt. The Dawn newspaper has reported that cement plants in Northern Pakistan accounted for 33.9Mt (76%) of despatches, while those in Southern Pakistan accounted for 10.7Mt (24%).
The All Pakistan Cement Manufacturers Association urged the government to support export-orientated industries. It said “Boosting exports will play a pivotal role in the revival of our economy. Signing of standby agreement with IMF is only an interim solution and we must use our own resources in order to build a stronger Pakistan.”
India: The government of Assam has laid the foundation stone for its upcoming Bogibeel Inland Waterways Transport Terminal, a cargo and passenger port on the River Brahmaputra in Assam. The Economic Times newspaper has reported that the state will invest US$5.67m in the port, which is scheduled to open in February 2024. Cement is among the commodities expected to travel through the port.
Assam’s Minister for Ports, Shipping and Waterways, Sarbananda Sonowal, suggested that a new local cement industry might arise to take advantage of the improved transport situation, alongside other industries.
Nigeria: Lafarge Africa's Roadcem product has been approved by the Federal Ministry of Works and Housing. The product is a cement additive that is used for soil stabilisation in road construction projects. It was developed to improve the characteristics of soils before they are used for the base, sub-base or sub-grade construction in roads.
Osita Ezedozie, the Director of Highways (Materials, Geotechnics & Quality Control), of the Federal Ministry of Works and Housing, said “Following the improved performance observed from the tests, pilot study and evaluation of Roadcem over ordinary Portland cement in soil stabilisation, approval has been granted for the introduction and use of Roadcem for stabilisation of soil in highway pavement sub-base course construction. At 5% Roadcem content, the stabilised sharp sand complies with all the specification requirements for a sub-base course and also achieves higher stability at a lower cost than stabilisation with ordinary Portland cement.”
India: Shiva Cement says that a proposed 1Mt/yr grinding unit as part of its new Sundergarh plant is on hold while it evaluates the site location. The cement producer confirmed that the 1.36Mt/yr clinker unit at the site in Odisha has been commissioned as well as a 9MW waste heat recovery (WHR) unit. It added that it has already obtained clearance to operate (CTO) from the State Pollution Control Board (SPCB) for 0.66Mt/yr of clinker production and 9MW WHR at the site. It is currently awaiting clearance for the remaining clinker production capacity. Work on alternative fuel systems, a 12km rail siding and a 10km overland belt conveyor at the site are reportedly progressing on schedule.
Philippines: Holcim Philippines and Sungshin Cement have signed a memorandum of understanding whereby Holcim Philippines will be priority supplier of cement for use in Sungshin Cement's ready-mix concrete operations in the Philippines, InPR News has reported. South Korea-based Sungshin is anticipating growing demand from infrastructure projects, partly due to a US$3bn development loan agreement between the government of the Philippines and South Korea.
US: The Mine Safety and Health Administration (MSHA) has fined Dragon Products for failure to comply with mine safety rules. The Maine Monitor newspaper has reported that inspectors issued 33 citations following an inspection of its quarry in May 2023.
Thomaston cement plant manager Jennifer Small said that the citations primarily relate to 'housekeeping,' and that the company has 'promptly addressed these citations and worked closely with the MSHA to improve plant safety.'
Dragon Products, a subsidiary of Giant Cement, paid mine safety fines worth US$150,000 in 2022, US$76,700 in 2021 and US$134,000 in 2020.
Update on synthetic fuels, June 2023
28 June 2023Cemex highlighted its Clyngas project at its Alicante cement plant in Spain this week. The project will produce synthesis gas (syngas) from different types of waste for direct injection into the burner at the plant during the combustion process. It is being run in conjunction with Waste to Energy Advanced Solutions (WTEnergy), a company that Cemex invested in at the end of 2022. It is also receiving Euro4.4m in funding from the European Commission (EC) as part of its innovation fund for small scale projects. The initiative estimates that it will save over 400,000t of equivalent CO2 during the first 10 years of the project's life by replacing petroleum coke with syngas.
Clyngas is another example of Cemex’s innovation with alternative fuels for cement and lime. It follows on from the group’s work with hydrogen injection into cement kilns. As presented at the 15th Global CemFuels Conference 2022 it has been using hydrogen in low volumes as a combustion enhancer in more than 20 plants worldwide. However, it was also looking into using hydrogen more directly as a fuel and as a feedstock for other alternative fuels. WTEnergy’s gasification process could potentially link up to this as it converts waste streams such as wood chips, agricultural waste, refuse derived fuel (RDF), solid recovered fuel (SRF), dry sewage sludge, meat and bone meal, poultry litter and plastics into syngas. WTEnergy then proposes that its gasification process and/or the syngas can be used for power generation and thermal applications. In the case of the Clyngas project it will be the latter, as the gasification process will be used to boost the burnability characteristics of RDF with a high biomass content. One part of this to note is that the syngas can potentially be used to manufacture hydrogen. This would be a useful capability for a cement company, for example, that was already using alternative fuels and was now considering further decarbonisation by switching to using hydrogen.
A few other cement companies have been looking at synthetic fuels too, but this has generally been as a by-product of carbon capture and utilisation. This week Lafarge France, for example, said it had signed a memorandum of understanding with Axens, EDF and IFP Energies Nouvelles for a synthetic fuel production trial. Its plan is to build a unit that will produce synthetic kerosene using captured CO2 from a carbon capture installation at Lafarge France's Saint-Pierre-La-Cour cement plant. The kerosene will then be sold to airlines. Other examples of cement companies looking at using captured CO2 to manufacture synthetic fuels include Finnsementti’s pre-engineering study with Aker Carbon Capture to consider producing methanol as a fuel for transport, Holcim’s and TotalEnergies’ various plans of what to do with the CO2 captured from the-to-be upgraded Obourg cement plant and Cemex Deutschland’s ambitions for its Rüdersdorf plant.
As can be seen above there are different types of synthetic fuels and cement companies are at the research and pilot stages. Although there isn’t a commonly accepted definition of what a synthetic fuel is, the general meaning is that of a fuel made from feedstock using a chemical reaction as opposed to, say, a refining process. The wide variety of potential synthetic fuels puts the confusion over the different types of hydrogen into perspective. However, this may be a problem for a later date if usage by cement companies becomes more serious.
What is a problem, though, has been the EC’s planned legislation to phase out the use of industrial CO2 in synthetic fuels by 2041. Cembureau, the European cement industry association, warned in late 2022 of the issues this would pose for industries trying to find a way to utilise their CO2 emissions where storage was too difficult or expensive. Its view was that while synthetic fuels using industrial CO2 are not fully net-zero, as the captured CO2 is later released into the atmosphere, it is a necessary short to medium term step for sectors trying to make the transition. Companies trying to build industrial-scale chemical plants for synthetic fuels need running periods of 20 to 30 years to achieve payback. As of March 2023 Cembureau was still concerned about the implication of proposed regulations, specifically with regards to the proposed criteria for which synthetic fuels could be used, based on their greenhouse gas emissions savings (at least 70% compared to the regular fuels being replaced). It directly linked this to synthetic fuels projects being launched by the cement sector that might be adversely affected by the new rules. The EC published the legislation in late June 2023 and it is set to become legal in mid-July 2023.
Using synthetic fuels either as a fuel or a by-product from cement production is an area of interest currently with the projects detailed above and others in progress. One vision for their use in Europe, at least, is that they might offer a route for carbon capture for cement plants without access to the logistic networks necessary for sequestration. Whether they find a place in cement manufacture either on a transitional basis or over a longer term should become clearer over the coming decade. Yet the EC’s new rules are likely to slow this process down as at least some of the planned pilots may become unviable in Europe. Other jurisdictions around the world take note.
Russia: Cementum is preparing to upgrade the grinding capacity at its integrated Ferzikovo cement plant in Kaluga region. The US$40m project will add 0.3Mt/yr of grinding capacity to the plant. Other planned developments include building a dry building materials unit and a concrete plant. Maxim Goncharov, the general director of Cementum and Vitaly Bogachenko, the Director of Corporate Relations and Sustainable Development of Cementum, met with Vladislav Shapsha, the governor of the Kaluga Region, in mid-June 2023 at the St Petersburg International Economic Forum to discuss development in the region. Holcim’s divested Russian business rebranded as Cementum in early 2023.
Cemros’ Serebryansky cement plant switches to gas
28 June 2023Russia: Cemros’ integrated Serebryansky cement plant in Ryzan region has switched to using gas as a fuel. The project was conducted with Gazprom and the regional government, including linking the site up to the gas network with a 14km pipeline. CO2 emissions at the plant are expected to decrease by up to 17% and electricity consumption by 4%. The 1.8Mt/yr plant used around 200,000t/yr of coal before starting the switch to gas from March 2023.
