Mineral Products Association welcomes UK cement carbon border adjustment mechanism plan
19 December 2023UK: The Mineral Products Association (MPA) has welcomed government plans for the implementation of a UK carbon border adjustment mechanism for cement by 2027. The association urged the government to develop policy and business models for carbon capture, use and storage, including supporting a domestic carbon neutral and negative products sector.
MPA executive director for energy and climate change Diana Casey said “We cannot take our supply of cement for granted and neither can we put ourselves at risk of unstable international trading markets. That is why today’s commitment to a UK CBAM is so important. Levelling the carbon cost between domestic production and imports will help the UK attract the investment required to decarbonise and ensure our long-term security of supply. The Government’s commitment to bring in the UK CBAM by 2027 is very welcome, and ideally it should be introduced in 2026 to align with the EU scheme. This is the only way to prevent any detrimental impact of the EU CBAM on UK industry.” She added “As well as a CBAM on cement, the MPA would be interested in exploring a CBAM on lime. However, the challenge for the lime sector is ensuring that lime exports can compete in international markets.”
Australia: Western Australia’s environment minister Reece Whitby has questioned the efficacy of tests submitted by Cockburn Cement in relation to its Munster lime plant in May 2023. The tests showed successes in odour reduction during sand feeding at the plant’s Kiln 6. Business News Western Australia has reported that the government and an independent expert have raised ‘areas of concern’ as to whether the trial represents normal operating conditions for the kiln.
David Scaife, who represents Cockburn District in the Western Australia Legislative Assembly, said "My gripe is not with the workers, it is with the senior management and the directors of Cockburn Cement and its owner, Adbri, who have refused to do the right thing either by moving the lime manufacturing operations to its Kwinana facility or at least making the investments necessary to eliminate the odour."
SigmaRoc buys CRH’s European lime business
22 November 2023Europe: Ireland-based CRH has agreed to sell its European lime business to UK-based SigmaRoc for US$1.1bn. The business controls 16 sites across the Czech Republic, Germany, Ireland, Poland and the UK. CRH says that the first phase of the transaction, which is scheduled for completion in early 2024, will hand over control of the Czech Republic, Germany and Ireland businesses to SigmaRoc, while control of the Poland and UK business will pass over in two subsequent phases.
CRH chief executive officer Albert Manifold said “The decision to divest at an attractive valuation follows a comprehensive review of the Business and demonstrates CRH’s active approach to portfolio management. The proceeds from the divestment will provide us with significant additional capital allocation opportunities to deliver further growth and value creation for our shareholders.”
Cemex UK supplies by-pass dust to farmers
24 October 2023UK: Cemex UK says that it has collected 130,000t of by-pass dust (BPD) from its Rugby cement plant in Warwickshire since 2015. The producer supplies the BPD to the agriculture sector, where it can replace traditional fertilisers and lime due to its high lime and potassium content. Additionally, Cemex UK has sponsored research into this and other circular economic uses of BPD, including an on-going study which claimed the Carbon Journey Award at the Eco Innovation North West Awards 2023.
Cemex’s Europe regional head of sustainability Paul Fletcher said “We are very proud of our partnership with Silverwoods and the considerable positive impact their innovation and expertise has had on our ability to reuse BPD for other applications. We believe it leads the way in our industry and presents real potential to be adapted elsewhere across our operations. Not only does it benefit the environment by reducing the amount of materials that need to be disposed of, but it generates a product that has a value for farmers and helps cut the use of traditional materials.” He added “This partnership demonstrates that to deliver true circularity, more industrial by-products, including those from different sectors of the economy, need to be used as secondary resources, rather than primarily be seen as waste. If this is to be achieved, a new perspective is needed to boost circular economy practices, with regulations and permitting supporting this proactively.”
Lhoist North America to add lime production capacity in Texas
28 September 2023US: Lhoist North America says it intends to add lime production capacity in Texas. It stated that population growth in the south of the country had created increased demand for its calcium-based products, with customers having announced new steel mills, liquefied natural gas (LNG) export facilities, lithium hydroxide production plants and water treatment facilities. In its view these expansions in multiple markets require lime both in the initial infrastructure build and in longer-term production processes.
The subsidiary of Belgium-based Lhoist said in mid-September 2023 that it was expecting to file permits for the expansion in the coming weeks and the location for the new production capacity will be revealed at a later date.

SaltX and SMA Mineral agree plant for electrified lime plants
05 September 2023Sweden: SaltX Technology and SMA Mineral have agreed a joint roadmap until 2028 to work on developing and building electrified lime plants. The agreement means that mineral producer SMA Mineral plans to build several units where SaltX's electric arc calciner (EAC) technology will be installed. The companies have worked together since mid-2022.
Carl-Johan Linér, the chief executive officer at SaltX, said "We have now signed a long-term cooperation agreement in which the respective parties' roles and responsibilities are regulated, which is an important step for both parties."
SaltX Technology is intended to allow SMA Mineral to halve its CO2 emissions by 2027. The agreement allows SMA Mineral to use the EAC technology to produce quicklime in the Nordic region. The forecast is that SaltX will receive orders for 7 - 9 EAC units from SMA Mineral during the contract period. SaltX intends to market and sell the EAC technology to lime manufacturers outside the Nordic region and other stakeholders, such as cement manufacturers, worldwide. SaltX and SMA Mineral are accelerating work on SMA Mineral’s first electric lime plant at Mo i Rana.
Maerz to supply lime kiln for UNACEM
30 August 2023Peru: Switzerland-based Maerz has received an order from UNACEM (Unión Andina de Cementos) to supply a 600t/day PFR lime kiln. The kiln will be built and operated jointly at Tarma by UNACEM and Mexico-based lime producer Calidra Group. UNACEM already runs its integrated Condorcocha cement plant in Tarma. The supplier says that the kiln will be ready to install future CO2 capture technologies due to airtight sealed charging and discharging systems. It will also save up to 20% of electrical energy compared to conventional rotary piston blowers by using high-pressure fans to provide the process air.
Planning is underway for the project and is expected to be completed by the end of 2023. Maerz’ scope of supply will include the petroleum coke firing system, skip winch, charging and discharging systems, high-pressure fans, hydraulic unit and control system.

UK lime sector commits to net zero by 2040
22 June 2023UK: Mineral Products Association Lime (MPA Lime), the body representing the UK lime sector, has launched the Net Negative 2040 Roadmap. The association said that the roadmap sets out the strategy for its to 'go beyond net zero' by 2040. The industry will rely on the deployment of fuel switching, carbon capture, renewable energy sources and green transport technologies, among other approaches. It called on the government to support its aims through the implementation of carbon accounting, subsidisation of renewables and decarbonisation technologies, the development of green hydrogen infrastructure, ensuring that UK lime can remain competitive in the UK and overseas markets.
MPA Lime director Mike Haynes said “Each lever will contribute to decarbonisation – many initiatives are happening already or will come on stream this decade." He added "The combination of using biomass fuels with carbon capture and lime product carbonation will result in removal of 250,000t/yr of atmospheric CO2, making the sector net negative overall. Other levers, especially indirect emissions and transportation, require broader collaboration and enabling action by government and other industries.”
Through their actions to date, MPA Lime members reduced their absolute CO2 emissions by 25% between 2005 and 2022.
