India: Tamil Nadu will host one of five national carbon capture and utilisation (CCU) testbeds aimed at lowering CO₂ emissions in the cement sector in a step towards the country’s 2070 net-zero target, according to The New Indian Express newspaper. The testbed will be located at UltraTech Cement’s Reddipalayam plant in Ariyalur district, supported by the Indian Institute of Technology Madras and Birla Institute of Technology and Science Pilani. The project is part of a Department of Science and Technology (DST) programme, which will trial an oxygen-enriched kiln system capturing up to 2t/day of CO₂ for mineralisation into concrete products. Other CCU testbeds are being established in Rajasthan, Odisha and Andhra Pradesh, with JK Cement and Dalmia Cement involved.

Union Minister for Science and Technology and Earth Sciences Jitendra Singh said the DST was currently processing financial sanctions for the projects, and full-scale implementation is expected in 2025.

Germany: Holcim, E.ON Energy Infrastructure Solutions and Orcan Energy have launched a large-scale waste heat recovery project at Holcim’s Dotternhausen cement plant to capture 10MW of unused heat from kiln exhaust gases. The recovered heat will supply internal processes, potential district heating networks and power generation via Orcan Energy’s eP1000 Organic Rankine Cycle (ORC) system. E.ON is responsible for the planning, construction, financing operation and maintenance of the plant as part of an Energy-as-a-Service model. This is intended to present no initial investment costs for Holcim.

Holcim South Germany plant manager Dieter Schillo said “This project marks an important milestone on our path to decarbonising cement production. The smart use of industrial waste heat not only reduces our Scope 2 emissions, but also strengthens our role as a pioneer in sustainable building materials.”

Germany: CI4C has installed the final modular component of its carbon purification unit (CPU) at the Schwenk Zement plant in Mergelstetten. The unit is 31m long with a cross-section of 5 x 5m, installed using a tandem lift.

The unit completes major construction work at the CO₂ capture pilot project. The CPU will clean and liquefy CO₂-rich exhaust gas from the oxyfuel kiln and processes it to food-grade quality, enabling its reuse in purified form. Final mechanical and electrical works are underway ahead of commissioning in late summer 2025.

European cement producers Buzzi, Dyckerhoff, Heidelberg Materials, Schwenk Zement and Vicat established CI4C in 2019 to implement the catch4climate initiative. The 450t/day clinker line and CPU have been purpose-built at the plant, which has received investment of over €120m, and will be used solely for research and development.

UK/Norway: UK-based marine carbon capture firm Seabound has launched an onboard carbon capture project in partnership with Hartmann Group, InterMaritime Group and Heidelberg Materials Northern Europe. The solution equips the UBC Cork, a 5700 gross tonne cement carrier, with Seabound’s calcium looping carbon capture system. This system captures up to 95% of CO₂ and 98% of sulphur emissions from the ship’s exhaust using calcium hydroxide to absorb the CO₂ and convert it into limestone that is stored onboard until returning to port. The captured carbon will be offloaded at the Port of Brevik for use at Heidelberg Materials’ Brevik cement plant, host of the first industrial-scale carbon capture facility in the cement sector.

The project is co-funded by the Eurostars partnership on Innovative SMEs, part of Horizon Europe through the Cyprus Research and Innovation Foundation. This funding supports collaborative research and development projects in a range of industries, including maritime transport.

CEO of Seabound Alisha Fredriksson said “We’re proud to partner with industry leaders like Heidelberg Materials and Hartmann to deliver scalable carbon capture solutions. We’re especially excited to be advancing this work in Brevik, a strategic location that’s rapidly establishing itself as a global hub for CCS with Heidelberg’s world-first facility and the Northern Lights pick up point. Together, we’re demonstrating how onboard carbon capture can accelerate emissions reductions in carbon-intensive sectors.”

Lars Erik Marcussen, Logistics project manager at Heidelberg Materials Northern Europe, said “Shipping cement is emissions-intensive, and Seabound’s system gives us a clear path to reduce those Scope 3 emissions while enhancing our circular use of captured CO₂. This project also brings us one step closer to decarbonising the logistics/transport part of our operations.”

UK: Holcim UK has welcomed a €33.1m investment by the National Wealth Fund into the Peak Cluster carbon capture and storage (CCS) project, which will decarbonise 40% of the UK’s cement and lime production and support over 2000 existing jobs, as well as creating new ones. Led by Progressive Energy, Peak Cluster is a partnership between Holcim UK, Breedon, Tarmac and Sigma Roc involving cement and lime plants in Derbyshire and Staffordshire, including Holcim UK’s 1Mt/yr Cauldon plant. The project aims to reduce annual carbon emissions from its partners by 3Mt/yr from 2032 (25% of annual CO₂ output for the area), by capturing CO₂ from the plants and transporting it by pipeline to Morecambe Net Zero's disused gas fields under the East Irish Sea.

The investment will fund front-end engineering and design (FEED) and other studies to support a final investment decision in 2028. Holcim UK CEO Lee Sleight said that CCS is ‘essential’ to decarbonise cement manufacturing and achieve net zero by 2050.

Peak Cluster CEO John Egan said it will create a ‘backbone of industrial opportunity’ across northern England.

Togo: Cement producers in Togo have committed to reduce CO₂ emissions by 2050 by lowering the clinker factor and increasing the use of alternative fuels. At a meeting in Lomé on 30 June 2025, manufacturers set out a roadmap that includes large-scale adoption of limestone calcined clay cement (LC3) to reduce clinker content from 65% to 40%, potentially cutting emissions by up to 40% without sacrificing performance, according to the Togo First newspaper.

The strategy also involves replacing coal with agricultural or municipal waste. Industry data shows that cement production generated 0.9Mt of CO₂ in 2023, which could rise to 1.8Mt by 2050 without intervention. Manufacturers are seeking regulatory support to help deliver the roadmap, which aligns with Togo’s Paris Agreement commitments.

Sweden: SaltX has announced a partnership with Holcim to develop technology and solutions that electrify and enable the decarbonisation of the entire cement manufacturing process. As part of the partnership, Holcim is becoming a strategic shareholder in SaltX through an investment of approximately US$4m. 

The companies intend to co-develop and advance SaltX’s electrification technology for calcination, including the production of Portland cement clinker. The goal is to be the first in the world to establish a scalable plant concept for fully electrified cement facilities. The parties’ intention is for the partnership to be extensive, featuring a collaborative go-to-market and scale-up plan. The initial focus is on developing the world’s first all-electric pilot plant for emission-free cement production. This will set the foundation to establish multiple large-scale production facilities based on SaltX’s electrification technology.  

Malaysia: Cementir Group subsidiary Aalborg Portland Malaysia has launched CEM II/A-LL 52.5N with 12% lower CO₂ emissions compared to Aalborg White CEM I 52.5N.
