France: Cem'In'Eu has launched FUSIOCIM, a CEM II/C pozzolan cement, that offers a 43% reduction in CO₂ emissions compared with ordinary Portland cement (OPC). FUSIOCIM has specific CO₂ emissions of 506kg/t. It is suitable for various concrete applications and comes in 25kg bags.

Cem’In’Eu general manager Fabien Charbonnel said "We created Cem’In’Eu with the ambition of reducing the carbon footprint of the cement industry. And we are proving it today with a low-carbon offer that easily replaces traditional cements, without any change for construction professionals. We are convinced that this transition can only be done with pragmatism and taking into account the needs of users.”

US: In 2022, Fortera began building a 15,000t/yr-capacity plant to produce its low-carbon cementitious material, Fortera Reactive Calcium Carbonate (RCC), at CalPortland's Redding cement plant in California. The commercial-scale plant will produce a reactive form of calcium carbonate using CO₂ from the kiln of the 600,000t/yr cement plant. Fortera's process converts 1t of limestone into 1t of Fortera RCC by capturing and mineralising CO₂ from the cement plant's kiln. Fortera cement production emits 60% less CO₂ than ordinary Portland cement (OPC). The 15,000t/yr plant will operate at 20 times the scale of previous pilot tests. The Redding Record newspaper has reported that 15 workers will be employed at the site.

Former Redding cement plant owner Lehigh Hanson formed an agreement with Fortera to collaborate on the low-carbon cement plant project in March 2021. The plant subsequently switched ownership to Martin Marietta Materials in October 2021, before CalPortland bought it in July 2022.

Argentina: Cementos Avellaneda has inaugurated its 22MW La Calera solar power plant in San Luis Province. Forbes has reported that the power plant will supply electricity to the producer's 1.1Mt/yr San Luis cement plant. As a result, operations at the plant will henceforth be 55% renewably powered. In total, the new solar power plant will eliminate 22,600t/yr-worth of CO₂ emissions. Engineering company Industrias Juan F Secco supported the installation of the US$25m plant, which took 16 months to build.

Cementos Avellaneda's general director José Luis Maestri said "It was key to the success of this project to have been able to find a strategic partner such as Industrias Juan F Secco, an Argentine company with more than 80 years of history and experience in the energy sector, which provided us with all its professionalism and commitment."

UAE: Lafarge Emirates Cement, part of Holcim, has awarded a contract to Mitsubishi Heavy Industries Group subsidiary Turboden to supply and install a 10MW waste heat recovery (WHR) system at its Fujairah cement plant. The system relies on ENGIE Solutions' organic Rankine cycle technology. The supplier says that the installation will reduce the 3.2Mt/yr cement plant's energy-related CO₂ emissions by 29,000t/yr (28%).

Turboden CEO Paolo Bertuzzi said "We are proud that Holcim Group, already our customer for three other WHR plants, has again chosen Turboden for this first project in the UAE. At COP 28, this year in the UAE, we will have the opportunity to present this energy-saving and CO₂-reducing project to raise awareness in energy intensive industries."

China: Asia Cement has launched its 2050 decarbonisation strategy, entitled 'Net-Zero Carbon Emissions By 2050 - Asia Cement Advanced Deployment.' The strategy consists of multiple pillars, namely 'alternative fuels,' 'reducing cement's clinker factor,' 'increasing renewable energy reliance' and 'carbon capture.'

During 2022, Asia Cement reduced its limestone, clay, iron and sand consumption by 266,000t, its coal consumption by 17,000t and its gypsum consumption by 56,000t year-on-year. This eliminated 95,100t of CO₂ emissions throughout the year, according to the producer.

Spain: Cementos Tudela Veguín plans to spend more than Euro62.5m on sustainability-enhancing upgrades to its three cement plants in Asturias and one in León. The plans consist of upgrades to fuelling systems that will enable the plants to use biofuels and hydrogen, as well as efficiency upgrades. The La Nueva España newspaper has reported that the producer is seeking to secure European Union (EU) funding for the project. The region of Asturias is eligible for Euro263m-worth of regional decarbonisation funding under the EU's Strategic Project for Economic Recovery and Transformation.

A planned second phase of upgrades will consist of the installation of carbon capture systems at the plants. They emitted 1.67Mt CO₂ in 2022. 1.12Mt (67%) arose from the decarbonisation of limestone and 0.55Mt (33%) came from the combustion of fuel.

Spain: Cemex España has secured Euro4.4m in EU funding for an upgrade to its Alicante cement plant in Valencia. The project will launch the use of Clyngas synthetic gas as alternative fuel (AF) at the plant. Thermochemical conversion specialist WtEnergy, a subsidiary of Cemex Ventures, will supply the syngas. The partners say that this upgrade will reduce CO₂ emissions by 400,000t per decade.

Parent company Cemex said "This project is part of Cemex’s Future in Action programme, which seeks to achieve sustainable excellence through climate action, circularity and natural resource management, with the primary objective of becoming a net-zero CO₂ company."

UK: 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.

US: Heidelberg Materials North America inaugurated its 2.4Mt/yr Mitchell cement plant in Indiana on 14 July 2023. The plant is equipped with a 3600 bag/hr rotary packer, and also boasts a 154,000t-capacity clinker storage dome. It will produce Heidelberg Materials North America's EcoCem Portland limestone cement (PLC), alongside other products. The producer said that the new plant will help to address US cement supply chain constraints amid a planned US$110bn infrastructure overhaul.

Heidelberg Materials North America president and chief executive officer Chris Ward said "The plant will reduce CO₂ emissions per tonne of clinker by almost 30%, mainly through operating on natural gas. Our investment in the Mitchell facility helps us lower our carbon footprint, while serving the growing demand for more sustainable products in this key market.”

Chile: Cemento Polpaico plans to invest US$67m in expanding its operations, with a focus on its Cerro Blanco cement plant in Santiago. Work will include the construction of a solar power plant and the expansion of the plant's limestone quarry. Meanwhile, Cemento Polpaico will upgrade the plant's kiln to increase its alternative fuel (AF) substitution rate to 75% from 13%. The upgrade will increase the production line's clinker capacity by 13% and reduce its CO₂ emissions by 20,000t/yr. Additionally, the producer will build a new 3000t cement silo.
