Germany: The EU Innovation Fund has granted funding to the GeZero carbon capture project at Heidelberg Materials' Geseke cement plant in North Rhine-Westphalia. The project consists of a 700,000t/yr carbon capture system and an oxyfuel kiln upgrade. A captive solar power plant will provide energy for the new systems. CO2 storage partner Wintershall Dea will receive purified liquefied CO2 from the capture system via its Wilhelmshaven distribution hub for storage under the North Sea.
Heidelberg Materials Germany general manager Christian Knell said “This project sets an important milestone for the cement industry and for effective carbon management in Germany. We are now counting on the tailwind of Germany’s future Carbon Management Strategy and the regulatory framework to come.”
CEO Dominik von Achten added “With GeZero, we will once again show how Heidelberg Materials’ pioneering spirit is paving the way for the decarbonisation of our industry. We will be the first to realise a full CCS chain for the capture, transport and permanent storage of all CO₂ emissions from an inland location in Germany. I appreciate the support of the EU Innovation Fund, which expresses both an important recognition and the required backing from the political side.”
US: Brimstone has announced a new method of ordinary Portland cement (OPC) with a negative carbon footprint. Brimstone's method uses carbon-free calcium silicate in the place of limestone. Its calcination also produces magnesium compounds, which naturally sequester further CO2 from the atmosphere. The technology will now proceed to the testing phase at an upcoming pilot plant in Reno, Nevada, before proceeding to commercial-scale production. Brimstone will then begin to market its OPC, along with supplementary cementitious materials produced by its process.
Brimstone's chief technology officer Hugo Leandri said “By delivering the exact same cement, we clear away the main obstacles to adoption, offering an opportunity to dramatically speed up the path to net-zero construction. The same buildings, bridges and roads being built today can be built tomorrow, without carbon."

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.”
GO CO2 carbon capture and storage project launched
11 July 2023France: Heidelberg Materials, Lafarge France, Lhoist and utilities provider TotalEnergies launched the GO CO2 carbon capture and storage project at the port of Nantes-Saint-Nazaire on 10 July 2023. The Le Marin newspaper has reported that the Euro1.7bn project will treat and liquefy captured CO2 for underwater storage. The initial participating plants will be Lafarge France’s Saint-Pierre-la-Cour cement plant and Lhoist’s Neau lime plant.
Preliminary studies will commence later in 2023, with an investment decision to be taken in 2027, for commissioning of the project in 2030. The consortium will initially process 2.6Mt/yr of captured CO2, rising to 4Mt/yr in 2050.
Fortera continues construction of low-carbon cementitious material plant at CalPortland's Redding cement plant
10 July 2023US: 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.
Kyrgyzstan: Kant Cement has successfully transitioned Grinding Unit 8 of its Kant cement plant to closed cycle grinding operations. Business World News has reported that China-based CNBM Beijing Triumph carried out the work. The transition has increased the unit's production capacity by 30 - 40%.
Kant Cement's general director Pavel Dekhtyarev said "The mill previously produced 40t/hr of CEM II cement and 30t/hr of CEM I cement. Now it produces 58t/hr and 50t/hr, respectively. With this productivity, it was possible to reduce the specific energy consumption by 30% and reduce dust emissions. In addition, closed circuit grinding allows us to produce high grades of cement that could not be obtained with open circuit grinding systems."
Lafarge Emirates Cement hires Turboden for Fujairah cement plant waste heat recovery plant
07 July 2023UAE: 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."
United Cement Group implements environmental social governance standards in Uzbek cement operations
07 July 2023Uzbekistan: 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.
