Czech Republic: Holcim Česko, owner of the Čížkovice cement plant, will construct a new calcined clay processing line with an investment of US$44m, marking the largest investment in its history. The project, beginning in January 2025 and aiming for completion by the end of 2026, aims to reduce energy use and end reliance on fossil fuels. The Czech Ministry of the Environment has contributed US$14.5m towards the construction.

Holcim Česko CEO Miroslav Kratochvil said "The new calcined clay processing line represents a revolutionary step in the cement industry. Calcined clays will become a key material in our company's new cement products and will have a significantly lower carbon footprint. This innovation will enable the company to make a significant contribution to environmental protection and emission reduction."

Austria: Holcim is set to significantly reduce its carbon footprint with the installation of a new clinker cooler system and a large-scale photovoltaic system at its Mannersdorf cement plant. The clinker cooler project is valued at approximately €10m, and aims to cut heat consumption and reduce CO₂ emissions by 18,000t/yr. Completion is expected in early 2025. The solar project will be fully operational by 2025, and will cover approximately 15% of the plant’s energy needs and reduce CO₂ emissions by an additional 12,700t/yr. 2.7MW of solar panels were erected at the site of the former chimney on the plant’s premises.

Plant manager Helmut Reiterer said "Sustainability requires decarbonisation, i.e. continuously reducing the CO₂ emissions from our production activities. We are placing an investment focus on energy-efficient production by modernising our machinery, but also on expanding green energy."

Brazil: Votorantim Cimentos has launched Blenture, a new brand of cement and concrete designed to reduce CO₂ emissions and promote sustainable construction practices.

Blenture cements and concretes, certified with environmental product declarations by AENOR, reportedly offer a 30% lower carbon footprint while maintaining quality, strength and performance.

Italy: Heidelberg Materials has launched a feasibility study at its Rezzato-Mazzano cement plant to explore a source-to-sink carbon capture and storage (CCS) solution, potentially making it the first in Italy to produce carbon-captured net-zero cement, according to the company’s press release. The aim of the study is to evaluate the feasibility of capturing CO₂ from cement production and transporting it via pipeline to the Ravenna CCS storage hub under the Adriatic Sea. Phase 1 of the Ravenna CCS project will be carried out with the help of a joint venture between Italy-based integrated energy company Eni and energy infrastructure subsidiary Snamprogetti, involving discussions between the three companies for a technical evaluation. The project aims to leverage Eni’s depleted gas fields in the Adriatic Sea, which would be converted for use as permanent CO₂ storage sites. The total storage capacity of these fields is estimated at more than 500Mt. Snam is committed to developing a pipeline network to transport CO₂ from emitters to the Ravenna CCS hub.  

Chair of the managing board of Heidelberg Materials, Dominik von Achten, said "We are excited to explore the economic feasibility of a carbon capture initiative in the Mediterranean. Our ambition at Heidelberg Materials is not only to implement a decarbonisation initiative that is highly efficient in terms of resources and energy, but also to provide an important impetus for the development of a regional CCS cluster."

Member of the managing board of Heidelberg Materials and responsible for Europe, Jon Morrish, said "With an aspired capture rate of more than 95% of our plant’s emissions, this initiative aims to explore options for industrial-scale CCS in Italy. This would enable us to supply locally produced, carbon captured net-zero cement under our evoZero brand to customers in the region."

US: Colorado-based energy company NovoHydrogen plans to establish a hydrogen production facility at the Ash Grove Cement plant near Durkee, Oregon. Funded by the 2021 federal Bipartisan Infrastructure Act, the plant aims to start producing hydrogen fuel by 2028, according to CEO and founder Matt McMonagle. The hydrogen produced would be stored at the plant to be used to fuel trucks and other vehicles on-site, as well as potentially being used to power the plant. The construction of the plant will reportedly create 50 jobs.

Phillip Teintze, manager at the Durkee plant, said "The Ash Grove Cement Durkee plant is active in many opportunities to decarbonise our industry. Solutions for low carbon cement manufacturing are significantly challenging in terms of processes and expense. The Durkee plant is excited to see the development of NovoHydrogen’s efforts with the Department of Energy’s Pacific Northwest Hydrogen Hub. As hydrogen becomes environmentally and economically viable, we believe our facility could act as a distribution site, and potentially utilise hydrogen as a fuel to displace traditional fossil fuels.”

India: Ambuja Cements has entered the Alliance for Industry Decarbonisation (AFID), becoming the first cement manufacturer worldwide to join this global platform. AFID aims to accelerate the net zero transition in energy-intensive sectors, like cement, in accordance with the Paris Agreement. Ambuja Cements has set a net zero target for 2050, with goals approved by the Science Based Targets initiative (SBTi). The company plans to invest US$1.2bn in renewable energy projects totalling 1GW and 376MW from waste heat recovery systems to power 60% of its expanded capacity by the 2028 financial year. This strategy will reportedly lower its carbon footprint, and utilise more than 8.6Mt of discarded materials in the financial year 2024.

Non-executive director of Ambuja Cements, Mr Karan Adani, said "This marks another significant step for Ambuja in its sustainability journey. We are already amongst the lowest emission intensity cement producers globally and are undertaking a number of strategic initiatives to further reduce our greenhouse gas emissions footprint. Being a member of the Alliance for Industry Decarbonisation will allow us to leverage the experiences of global cross-sector industry peers. And, in turn, share our approach to decarbonisation."

Canada: Geocycle and Lafarge Canada, together with the Department of Natural Resources Canada, have opened a new low-carbon fuel plant at the Lafarge Canada Brookfield cement plant in Nova Scotia. The facility, which cost over US$7.5m and received US$2.6m in federal funding, will convert 14,000t/yr of discarded materials headed for landfill into low-carbon fuels, reducing the plant's reliance on fossil fuels and its carbon emissions by over 12,000t/yr. The materials to be repurposed include plastic and construction and demolition materials. The cement created at the facility will be used to make concrete for construction projects in the local area and is expected to create jobs for the local community.

President and CEO of Lafarge Canada (East) David Redfern said "Cement is a vital component of infrastructure projects that contribute to economic growth.
