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.

India: Prism Cement has taken delivery of a pendulum cooler supplied by Germany-based IKN at its Prism cement plant in Maharashtra. The new equipment will replace the 6.1Mt/yr plant's existing air beam technology cooler. The supplier says that this will help to improve the efficiency of waste heat recovery (WHR) processes at the plant.

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.”

Brazil: Votorantim Cimentos has secured a US$150m loan from the International Finance Corporation for an upgrade to its Salto de Pirapora cement plant in São Paulo. The producer aims to increase the alternative fuel (AF) substitution rate at the 4.8Mt/yr plant, and reduce its CO₂ emissions. It says that the loan is tied to sustainability performance indicators (SPIs), based on the reduction in the plant’s Scope 1 CO₂ emissions.

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.

India: UltraTech Cement and other industrial partners are participating in the development of the World Economic Forum’s first net zero transport cluster in India. The cluster, called Moving India, will deploy 550 zero-emissions trucks in western Gujarat and Maharashtra. Participants aim to create scale, support the deployment of shared assets and infrastructure, encourage the creation of a vehicle supply and servicing ecosystem and inform policy through consensus.

GPEO News has reported that UltraTech Cement managing director Kailash Jhanwar said "India is the second largest cement producing country in the world, with cement plants spread across the country. The cement sector can provide an ideal use case for early adoption of zero emission trucks. At UltraTech Cement, we are committed to evaluating all means to reduce our emissions and environmental footprint. We see large scale deployment of zero emission trucks and liquefied natural gas/compressed natural gas vehicles as the next key initiative to make our operations more sustainable."

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.
