Türkiye: Medcem has completed testing of its new waste heat recovery (WHR) facility, which will recover 25% of the energy demand of the plant’s second rotary kiln line commissioned in 2024.

The 9.6MW facility uses an organic rankine cycle (ORC) system to generate electricity from a single heat source. The company says that this will lead to significant cost savings in energy expenses while also reducing CO₂ emissions.

Australia: Boral will receive US$15.4m in government funding for a kiln feed optimisation project at its Berrima Cement Works, with CO₂ emissions expected to reduce by up to 100,000t/yr, based on predicted production rates. The Powering the Regions grant will support the producer’s installation of a new specialised grinding circuit and supporting infrastructure, which will raise the use of alternative raw materials in kiln feed to 23% from 9%, lowering the amount of limestone used.

Boral will use steel manufacturing by-products and industrial waste, including granulated blast furnace slag, steel slag, cement fibre board, fly ash and recycled fine concrete aggregates. The project will be operational in 2028.

The head of innovation and sustainability at Boral, Ali Nezhad, said “In terms of the resulting emissions intensity of the manufactured clinker, the project will result in up to 11% reduction in clinker emission intensity, 9% attributable to a reduction in calcination emissions and 2% attributable to thermal efficiency gains.”

India: Dalmia Cement (Bharat) will procure 10MW of solar power from Kilavikulam Rajalakshmi’s captive plant in Tamil Nadu. The producer will also acquire a 35% equity share in the solar power developer.

Kilavikulam Rajalakshmi is a special purpose vehicle for the 10MW solar project. Dalmia Cement said the acquisition will increase its renewable power supply as part of its commitment to RE100 by 2030 and becoming carbon negative by 2040.

The European Union (EU) is set to launch its Green Deal Industrial Plan, today, on 26 February 2025. It is the latest plan to help industry in the region reach net zero whilst remaining competitive. Key parts of the scheme that have been seen by the media include support for industries facing high energy prices, tax breaks for decarbonisation projects, simplifying the cross border adjustment mechanism (CBAM), linking funding for industrial CO₂ cutting more directly to revenue gathered from the emissions trading scheme (ETS) and revamping procurement rules.

Cembureau, the European cement association, presented its comments on the impending announcement earlier this week. On CBAM it said that more work was required on exports, “such as export adjustment or continued free allowances for exported goods through the application of the destination principle which merits more in-depth analysis and discussion as to its WTO compatibility.” On financing it called for 75% of ETS taxation on the cement sector to be funnelled straight back again in the form of a cement decarbonisation fund. On infrastructure it called for competitive access to low-carbon energy sources such as thermal biowaste and electricity. It also lobbied for the rapid-development of CO₂ pipelines and storage sites. Finally, on lead markets it asked that concrete carbonation and CO₂ use in construction materials be recognised as a carbon sink and that carbon capture and utilisation using CO₂ from industrial sectors be acknowledged through a review of the CO₂ accounting rules in the ETS.

Lobbyists from the other side of the argument, also ahead of the official unveiling of the Green Deal Industrial Plan, took a dim view of the ETS. A report published by Carbon Market Watch and WWF called for greater scrutiny to be placed on the scheme. Its argument is that the “current architecture of the EU ETS continues to reward heavy polluters by granting them free allowances instead of incentivising emissions reductions.” Holcim, Heidelberg Materials and Cemex were each singled out as having received more free allowances under the ETS than the actual emissions they were responsible for in 2023. The report also reflected the growing environmental backlash against carbon capture and utilisation and/or storage (CCUS). In its view the money from the ETS going into the Innovation Fund should be directed at schemes that directly reduce emissions, not at CCUS projects, although it did concede that the cement and lime industries were some of the few sectors that should be allowed funding towards CCUS. This may be a point for the cement sector to watch for in the future if there ends up being a wider backlash against CCUS in general.

The Carbon Market Watch-WWF case is that the cement sector (and others) have received far too many free allowances in the ETS for far too long. The authors admit that the allowances are set to fall fast, to 2034, as the CBAM comes in but they don’t think that anywhere near enough has been done. This has not been helped over the years by news stories occasionally emerging of idled cement plants appearing to make money from emissions allowances. These occurrences date back to the drop in production following the financial crash in 2008 but there have been more recent examples.

As Graph 1 above shows the environmentalists may be overstating their point on the ETS given that emissions were higher than the free allocation in 2018, 2019, 2021 and 2022. Roughly speaking, both the allowances and emissions by the cement sector from clinker production have been dropping since 2017 and further back to the mid-2000s. The system is intended to squeeze emissions but it doesn't take into account short-term variations in market conditions. Cembureau data shows that production rose in 2021. Sure enough, emissions jumped above the allocation. Although the cement production data is yet to be released for 2023, it is looking fairly likely that it will have decreased. Hence, emissions have fallen below the allocation level.

Few are likely to be happy with the EU’s Green Deal Industrial Plan. For producers, it is unlikely to add sufficient support against the additional ‘green’ cost burden. For environmentalists, it doesn't go far enough. The usual equilibrium for EU sustainability legislation is aiming at the target of net-zero without killing industry. The current US administration has further tipped this balancing act with its threats to fight against CBAM and the like with trade tariffs. Tom Lord, Redshaw Advisors described the EU ETS as a political construct at the Global FutureCem Conference that took place in February 2025 in Istanbul. This also applies to the EU’s green legislation (like any laws). Subsequently, certainty is a word that crops up frequently in discussions about EU green policies. Can EU industry be certain that these political constraints remain should circumstances change? With the ETS allowances dropping, CBAM coming and industry facing higher energy prices than its competitors, we’re about to find out how committed the EU is on net-zero and who the winners and losers will be.

Mexico: Holcim México has mitigated 1.7Mt of CO₂ emissions in housing and infrastructure projects throughout the country in 2024, according to a press release, through its ECOPact, ECOPlanet and ECOCycle sustainable products.

Holcim’s ECOPact low-carbon concrete reduces CO₂ emissions by at least 30% and represents 15% of its concrete sales, with a target of 27% by 2027. Its ECOPlanet cement range reduces CO₂ emissions by 35-65% relative to traditional blends and accounts for 56% of cement sales, with a target of 77% by 2027. ECOCycle technology incorporates recycled construction and demolition materials into concrete for non-structural applications like pavements.

Brazil: Buzzi subsidiary Cimento Nacional has signed a 15-year power purchase agreement with renewable energy provider Casa dos Ventos for 65MW/yr of wind power from the 756MW Serra do Tigre and 360MW Babilonia Sul wind farms. The agreement will supply 100% of the producer's electricity requirements in its Brazilian facilities.

The Serra do Tigre wind farm is currently under construction in Rio Grande do Norte, but the Babilonia Sul wind farm is operational in Bahia.

US: Eco Material Technologies has secured a US$800m green term loan facility. The facility will mature in 2032. Eco Material Technologies will invest the funds in expansion to its supplementary cementitious materials (SCM) production capacities, to raise them to 20Mt/yr.

The company noted the oversubscription of the raise as demonstrative of high confidence in its proposition for the decarbonisation of cement and concrete.

Taiwan: Asia Cement Corporation (ACC) has published its inaugural Nature-Related Financial Disclosures Report for 2025. The report adopts the Task Force on Nature-Related Financial Disclosures’ framework to evaluate the nature-related impacts of ACC’s operations. It already publishes an annual Climate-Related Financial Disclosures Report.

Since 2020, ACC has invested US$21.5m initiatives aimed at promoting nature, including its successful rehabilitation of golden birdwing butterflies.

India: Titan Cement Group has entered the South Asian market through a joint venture with India-based supplementary cementitious materials producer JAYCEE. The producer will hold a majority stake in the new company Atlas EcoSolutions. The venture will source, process, market and distribute supplementary cementitious materials globally in order to help its customers build sustainable construction projects using alternatives to clinker-based cement.

Head of supply chain and energy development Jean-Philippe Benard said "This joint venture aligns perfectly with our strategy to remain at the forefront of low-carbon building materials and highlights our unwavering commitment to sustainability and innovation. Entering the South Asian market positions us in a region with vast potential, both in market demand and sustainability impact. Securing long-term access to SCMs provides Titan Group a key alternative for strategically diversifying its portfolio with new low-carbon cements."

Germany: The Carbon Management Allianz (CMA), an association of emissions-intensive industrial producers in Germany, including cement companies, has urged lawmakers to legislate a framework for carbon capture, utilisation and storage (CCUS) in the country.

Energie & Management News has reported that CMA Chair Alexandra Decker said “Delays jeopardise investments. Regulatory clarity is urgently needed to scale these technologies and achieve the cement industry’s decarbonisation goal by 2039.”

Germany is due to elect a new parliament and government on 23 February 2025.
