Switzerland: Reduced-CO₂ cement catalyst developer Nanogence has secured an undisclosed sum from a consortium of investors led by investment fund CirCap. Nanogence’s catalyst reduces the CO₂ emissions of cement production by 40%, without changing production processes. Tech EU News has reported that the catalyst is capable of increasing cement’s strength and durability compared with that of ordinary Portland cement (OPC) produced without it. Prior to the latest financial development, the company had raised US$2.7m-worth of funding.

CEO Abhishek Kumar said “We are excited to receive the support from incoming renowned investors in this essential journey to accelerate the transition towards a low carbon built world. With growing demand worldwide, we need to align with like-minded strong backers for our growth phase.”

US: The US Department of Energy has awarded C-Crete Technologies US$2m in funding. C-Crete Technologies is developing a method for using CO₂ captured at industrial sources or from the air as an ingredient in its cement-free concrete. The binder will produce almost no CO₂ and continue to absorb more CO₂ from the air over time. It offers scalability and cost-parity with conventional cement for concrete producers, according to the developer.

C-Crete Technologies president Rouzbeh Savary said “We are committed to crafting a cement-free, carbon-negative ready-mix concrete that doesn’t just mitigate CO₂ emissions but actively contributes to reversing climate change. Our aim is nothing short of revolutionising this hard-to-abate, carbon-heavy sector.”

UAE: Emirates Cement (Arkan) has appointed Oman and Etihad Rail Company (OER) to provide train transport for imported Omani limestone to its 1Mt/yr Al Ain cement plant.

Saeed Khalfan Al Ghafri, CEO of Emirates Cement (Arkan)’s parent company, Emirates Steel Arkan Group, said “Our collaboration with OER enhances our supply chain capabilities by leveraging the railway network that connects both countries. This agreement paves the way for integrated logistics solutions for transporting raw materials to and from our cement plant in Al Ain, boosting operational efficiencies and cost-effectiveness and reducing environmental impact.”

Spain: Cementos Molins inaugurated its new Euro6.6m headquarters in Sant Vicenç dels Horts, Catalonia. The facilities include a 3250m² solar power plant, which will supply 100% of the energy consumed in the building’s operations. The solar power plant consists of an array of 1455 photovoltaic panels. Cementos Molins says that it also used recycled materials where possible in building its new headquarters.

CEO Julio Rodríguez said “We celebrate 95 years of life and we feel proud to contribute to the development of the country and its social evolution. In our DNA is the will to collaborate with our environment.”

Ghana: CIMPOR has appointed Germany-based ThyssenKrupp Polysius to build a 1280t/day flash activator for clay. The activator will supply calcined clay for use in the production of cement with a clinker factor as low as 50%. This can reduce the cement’s CO₂ emissions by 40% compared with ordinary Portland cement (OPC). The supplier’s contract covers engineering, supply of core equipment and supervision of the project. The equipment includes parts for clay handling, a hammer mill, a flash dryer and preheating and cooling equipment, as well as storage silos. The activator will be natural gas-fired.

Polysius Activated Clay product owner Leo Fit said "Our technology is not only more environmentally friendly, but also creates cost benefits for our customers like CIMPOR. In many regions, limestone is scarce and clinker has to be imported at high cost. At the same time, suitable clay sources are available. The increasing pressure to reduce greenhouse gas emissions is leading cement manufacturers to rethink. They need an alternative that is cost-efficient and at the same time provides high-quality cement. This is exactly what Polysius activated clay offers."

India: A report by the Council on Energy, Environment and Water (CEEW), funded by power provider BP, has estimated that India’s cement and steel sectors will require capital expenditure (CAPEX) investments of US$627bn in order to reach net zero CO₂ emissions. The report stated that waste heat recovery (WHR) and other efficiency-enhancing upgrades to cement plants can immediately reduce the industry’s emissions by 32%.

United News of India has reported that CEEW CEO Arunabha Ghosh said "Incentivising renewable energy will play a pivotal role in decarbonisation, through lower or no transmission charges at central and state levels. The government of India should develop a policy for and expedite the establishment of a carbon capture, utilisation and storage ecosystem to abate more than half of the emissions from the existing steel and cement plants.” Ghosh added “Since hydrogen will play a key role in its implementation, the next phase of the National Green Hydrogen Mission should focus on this agenda."

UK: First Graphene and Breedon Group have entered into a development and commercialisation agreement. Together, the companies aim to enhance Breedon Cement’s CEM II Portland limestone cement (PLC) through the use of First Graphene’s graphene enhanced grinding aids and cement admixtures. Breedon will provide increased access to cement production lines in order to optimise the understanding of the processing environment and operating conditions.

Breedon Group’s Hope cement plant in Derbyshire previously conducted a 24-hour graphene-enhanced cement production trial on 28 June 2023.

West Africa: Ciments de l'Afrique (CIMAF) plans to produce limestone calcined clay cement (LC3) at cement plants in West Africa. Parent company Omnium des Industries et de la Promotion (OIP) plans to build a calcined clay production facility in Burkina Faso to supply the material. Gulf Oil & Gas News has reported that OIP secured a Euro45m loan from World Bank Group’s International Finance Corporation on 10 October 2023. It will invest Euro32.4m in construction of its upcoming calcined clay production facility and Euro12.6m in
construction of solar power plants for three CIMAF subsidiaries in Burkina Faso, Chad and Mali.

CIMAF CEO Anas Sefrioui said "IFC's green loan provides essential long-term financing for our projects in Africa. Through the green loan structure, we are bringing the best practices in financing decarbonisation initiatives in the region. We look forward to reducing our carbon footprint and replicating these best practices in our African operations.”

El Salvador: Holcim El Salvador says that its first electric cement truck will enter operation at its El Ronco cement plant later in 2023. Local press has reported that this will reduce the plant’s carbon footprint by 560t/yr. The El Ronco plant is the subject of an investment in renewable energy infrastructure to cover 21% of its electricity consumption. The company is also investing in circular economic practices with a view to achieving net zero CO₂ emissions.

Holcim El Salvador chief executive officer Rodrigo Gallardo said "We are building more with less, incorporating recycled materials into our production processes, giving them a second life in order to use only what is necessary and thus contribute to preserving our planet." He added “We are building progress for people and the planet, with the vision of making sustainable construction affordable for everyone. The future of construction in El Salvador is being transformed, and we are proud to be leading the way, as we have done for the past 74 years."

Asia/Middle East: South Korea-based Samsung Engineering and Canada-based Svante have signed a new memorandum of understanding (MoU). Under the MoU, the companies will collaborate on the development and deployment of carbon capture technology in cement and other industries in Asia and the Middle East.

Svante President and CEO Claude Letourneau said “Samsung Engineering’s more than 50 years of experience in the energy and industrial sectors will be invaluable as we continue to rapidly expand our operations and filter production capabilities.”
