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."

Spain: Cementos El Molino plans to invest Euro3.7m in an upgrade to energy infrastructure at its 450,000t Santa Eulalia grinding plant in Aragon. Alimarket Construction News has reported that the upgrade consists of a 12MW substation and a 2.4MW solar power plant. Euro2m-worth (54%) of investments will go towards construction of the subsystem and Euro1.7m (46%) towards the solar power plant. Cementos El Molino expects to carry out the investments before the end of 2023.

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."

Uzbekistan: United Cement Group (UCG) has implemented environmental social governance (ESG) standards across its Uzbek cement operations. The new standards establish transparency on the company's legal compliance, working conditions and impacts on all stakeholders.

Business World Magazine has reported that general director Serik Ukanov said "Control of emissions of harmful substances and compliance with ESG norms is carried out by each enterprise under the supervision of the holding company. Each factory of the holding has a separate 'Targets' department, which is responsible for operations, repair and maintenance, as well as the adjustment of all the dedusting installations of raw materials and grinding mills and rotary kilns. We produce monthly and quarterly emissions reports and keep statistics on the carbon footprint per tonne of cement." He continued "UCG's next big step is a multi-phase project to reduce this carbon footprint. A contract was signed with KHD Humboldt Wedag to renovate two rotary kilns."

UCG subsidiary Qizilqumsement said that it was carrying out testing at its Qizilqum cement plant in partnership with Germany-based KHD Humboldt Wedag in May 2023. The company is in the process of expanding the plant's integrated capacity by 1.8Mt/yr through the construction of its upcoming Line 4.

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.

Peru: UNACEM Peru said that it reduced its CO₂ emissions per tonne of cement by 2.7% year-on-year during 2022. Throughout the year, the company reduced its electricity consumption by 3.4%. It sourced 90% of its electricity from renewable sources and met 70% of its fuel needs with natural gas. UNACEM Peru is committed to reaching carbon neutral cement production by 2050.

In terms of community engagement, the producer benefitted 76,700 people through its social infrastructure investments and 14,1000 people through its dialogue space initiatives, and provided its remote health guidance service to 3000 people.

Austria/Germany: Rohrdorfer Group and gas network company Bayernets have published a feasibility study for a proposed CO₂ transport network in Bavaria in Upper Austria. The first stage of the CO₂peline plan will be to create an ‘island’ network between the Rohrdorfer cement plant in Upper Bavaria and the so-called ‘Bavarian chemical triangle.’ An additional connection to the industrial and chemical region of Linz in Austria would add additional CO₂ sources, places of use and temporary storage sites to the grid. Further expansion plans could see the network expanded to cover the whole of Bavaria. A future connection to a Germany-based national network and international routes could further link the network to other locations where CO₂ is both produced and used, as well as creating routes to sequestration sites.

No dates have been released for the proposed CO₂ pipeline network. However, the project notes that Germany is aiming for carbon neutrality by 2045 and Bavaria and Austria by 2040.

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.

Thailand: US-based Rondo Energy and Siam Cement Group (SCG) plan to expand the production capacity of a heat battery storage unit at a SCG plant to 90GWh/yr. Once complete the site will reportedly have a production capacity larger than any current heat battery-supported manufacturing facility worldwide and will save up to 12Mt/yr of CO₂. The SCG site already has a capacity of 2.4GWh/yr.

SCG’s executive vice president Thammasak Sethaudom said “Rondo offers an innovative solution to reduce the carbon emissions from industrial process heat used in factories worldwide. SCG can use Rondo’s technology to lower our own carbon emissions and SCG Cleanergy can partner with Rondo to help our customers cut emissions.” He added “We also realised that we can leverage our 70 years of technical expertise in the refractory business and supply chain.”

Rondo heat batteries consist of refractory bricks capable of storing renewable energy as heat. The heat energy can then be returned to an industrial process as hot air or steam. SCG invested in Rondo Energy in 2022.
