France: Vicat and Materrup plan to build their first reduced-CO₂ MCC1 raw clay cement plant at Carbonne in Occitanie. The plant will have a capacity of 60,000t/yr. Vicat and Materrup plan for their joint venture to subsequently build three further units across France.

Vicat's chair and chief executive officer Guy Sidos said "This new structure will enable Vicat to provide complementary very low-carbon solutions and meet the different needs of players in the construction sector. Development prospects are promising."

India: CK Birla Group subsidiary Orient Cement has concluded a share subscription and shareholders' agreement with Cleantech India to acquire a 29% stake in Ardeur Renewables for US$1.16m. Ardeur Renewables is building a 16MW solar power plant at Orient Cement’s Chittapur cement plant in Karnataka and a 5.5 MW solar power plant at Orient Cement’s Jalgaon cement plant in Maharashtra. The cement producer says that the acquisition will help it to further increase its renewables usage and optimise its energy costs.

Nigeria: Lafarge Africa has applied to the Standards Organisation of Nigeria (SON) to use the product name Roadcem for its CEM-II Portland limestone cement (PLC) when sold in bulk. The Nigeria Tribune newspaper has reported that Lafarge Africa supplies PLC in bulk for use as a soil stabiliser in roadbuilding. It sells supplies the product bagged to retailers as Classic PLC.

SON certified Lafarge Africa's PLC under its Mandatory Conformity Assessment Programme.

Greece/US: Titan Cement Group has made new venture capital investments in two US-based disruptive technology suppliers. The cement producer enlarged its investment in energy storage specialist Rondo Energy, which has developed the Heat Battery. The technology enables cement plants and other industrial operations to access a constant supply of electricity using captive renewable energy sources. It also invested in venture capital firm Zacua Ventures, which handles a portfolio of companies involved in developing optimisation, automation and Construction 4.0 technology, including products relevant to the cement industry.

Titan Group Chief Sustainability and Innovation Officer Leonidas Canellopoulos said “We are committed to embracing innovation and fresh perspectives. By engaging with advanced construction and green technology startups through direct and indirect investments, as well as collaborations, we intend to forge more partnerships in the sector.”

World: The Global Cement and Concrete Association (GCCA) and Leadership Group for Industry Transition (LeadIT) launched the Green Cement Technology Tracker on 20 July 2023. The Green Cement Technology Tracker presents users with a real-time overview of active initiatives to reduce CO₂ emissions in the global cement industry. At present, the tracker covers carbon capture projects, which account for 36% of planned emissions reductions under the GCCA’s 2050 Roadmap for Net Zero Carbon Concrete. The partners plan to subsequently expand the scope of coverage to other emissions reduction technologies.

GCCA CEO Thomas Guillot said “Unleashing technology such as carbon capture, utilisation and storage is key to achieving our net zero mission in our sector. Carbon capture pilots, projects and announcements are picking up pace across the world. This technology works, and our next goal is to scale up, working with stakeholders such as governments and the investment community to help transform the industry worldwide.”

UK: A team at Imperial College London has won a US$1.27m grant for its research into developing carbon negative cement from silica. The research won the Department for Energy Security and Net Zero (DESNZ)’s Carbon Capture, Usage & Storage (CCUS) Innovation 2.0 competition. The Imperial team sources its silica from natural olivine. It says that the compound behaves in the same way as other supplementary cementitious materials. Meanwhile, magnesia from the decomposition of the olivine can serve as a carbon sink in the form of magnesium carbonate. It, in turn, could serve as a raw material for concrete block production.

The DESNZ’s Net Zero Innovation Portfolio, of which the CCUS Innovation 2.0 competition is a part, has a budget of US$1.29bn.

Ivory Coast: LafargeHolcim Côte d'Ivoire has invested a total US$677,000 in sustainability-enhancing upgrades to its 2Mt/yr Abidjan grinding plant since 2020. Agence Ivoirienne de Presse has reported that the producer has now implemented 80% of recommendations made by sustainability auditor Centre Ivoirien Antipollution (CIAPOL). Recommendations included the installation of dust capture systems.

General manager Rachis Yousry said "In 2022, LafargeHolcim received zero complaints from local residents for environmental degradation.” He added the producer was on track to realise net zero CO₂ emissions by 2050.

Germany: Dyckerhoff has launched Dyckerhoff Weiss Blue Star, a pozzolanic white cement CEM IV/A (P) 42.5 R product. It was approved by the German cement association, the VDZ, in mid-June 2023 and is now being manufactured at the Amöneburg plant. The lower CO₂ credentials of the new product have been promoted as it releases around 15% less CO₂ compared to CEM I cements. It is also notable for being a blended white cement.

Greece: The IFESTOS carbon capture project at Titan Group's Kamari cement plant was among eight CO₂ emissions-reducing projects chosen for funding following the latest EU Innovation Fund call for projects. IFESTOS consists of a planned 1.9Mt/yr carbon capture installation at the Kamari plant. Titan Group says that it has concluded necessary memoranda of understanding (MoUs) with suppliers. The IFESTOS project will receive a share of a funding pot worth a total Euro3.6bn.

Chair Marcel Cobuz said "We are truly excited that the European Commission has chosen to support our large-scale, highly innovative project. IFESTOS is a cornerstone of our accelerated decarbonisation roadmap to net-zero. In line with EU climate policy, together with our technology partners, we are pioneering an innovative carbon capture project, the largest in Europe, with a highly positive impact. The group has strong capabilities and is committed to executing this project fast over the next few years, decarbonising production and offering green growth opportunities to our customers in Europe. We embrace the opportunity to widely share our knowledge and expertise and promote green cements as modern materials for infrastructure and housing.”

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.”
