India: UltraTech Cement has awarded a contract to Vibrant Energy to build a 21.6MW wind farm in Maharashtra. The wind farm will provide energy for UltraTech Cement’s cement plants in the state.

Saur Energy has reported that Vibrant Energy chief executive officer Srinivasan Viswanathan, said “We are excited to partner with UltraTech and accelerate their green energy transition. This partnership marks a significant step towards a sustainable and carbon-neutral future. This will act as a catalyst for transforming not just the cement industry, but other energy-intensive industries as well.”

France: The French cement sector association, France Ciment, has called on the government to make ‘heavy investments’ in the industry amid its on-going transition to net zero CO₂ cement production. It estimated the total cost of its transition, which will include carbon capture, at Euro3.5bn,according to Les Echos newspaper. The association said that producers currently benefit from the government’s partial price cap on electricity for industrial plants. It sought clarity as to whether the cap will remain in force beyond its scheduled limit in 2025. Lafarge France said that capped prices covered 50 – 60% of its electricity consumption in 2022.

Norway: Heidelberg Materials Sement Norge set in place a 220t absorber unit at its Brevik cement plant on late August 2023. The unit will form part of the upcoming 400,000t/yr carbon capture and storage (CCS) installation at the site. It expects to complete the installation of the absorber unit within two weeks of its placement. In September 2023, Heidelberg Materials Sement Norge will proceed to install the system’s 100m-high absorber stack.

Brevik CCS operational manager Tor Gautestad said “The absorber is in many ways the heart of the carbon capture process, because it is where the flue gases are separated.”

US: Terra CO2 has performed a successful demonstration pour of its OPUS silicate-based supplementary cementitious material (SCM) at a construction site in Texas. Terra CO2 supplied the SCM to indiGO Auto Group for the construction of its Porsche Sugar Land car dealership in Houston. It says that the product delivers durability, strength and functionality on a par with other, traditional SCMs. Tonne-for-tonne, the use of OPUS reduces projects’ CO2 emissions by 70%, and their NOx emissions by 90%, compared to ordinary Portland cement (OPC).

Terra CO2 CEO Bill Yearsley said "Our work at Terra CO2 is about forging a viable path for sustainable construction. We're set on creating a blueprint for the future where performance, cost-effectiveness and sustainability coexist seamlessly across projects. We're moving beyond the lab, beyond the processes that have held us back as an industry, and introducing a sustainable solution to real-world applications."

Mexico: Cemex Mexico subsitituted 36% of it cement fuel with alternative fuel (AF) in 2022. This exceeds the Mexican cement industry’s target for 2030, of 32%. Mexico Business News has reported that the producer used 1.05Mt of AF across its operations. This reduced its CO₂ emissions by 1.8Mt, and prevented 850,000t of methane emissions from being generated in landfill. Cemex Mexico’s Huichapan cement plant in Hidalgo set the company record for the year, with 207,000t of AF co-processed in its cement production. It produced 3.2Mt of cement for the Bajio, Central, Central-North, Laguna and Southeast Mexico markets.

Sustainability Manager Carlos Medina said "Last year’s results motivate us to intensify our efforts and uphold good practices that benefit communities and the environment. We will keep promoting environmentally friendly solutions in all our operations, as we are convinced that all social actors must collaborate to lay the foundations for a better future."

Austria: Christine Gröll has taken over the role of head of material flow management and process control at Alpacem Zement Austria. The producer created the new role for Gröll, who will lead a dedicated team of eight people to achieve net zero CO₂ cement production at the company’s Wietersdorf cement plant by 2035. The team will focus on alternative raw materials and alternative fuel (AF) substitution.

Gröll is an Ulm University-trained chemist with over four years’ experience working within Alpacem Zement Austria. Prior to that, she worked as a research associate for Schwenk Zement in Germany, on the development of its Celitement hydraulic binder.

Alpacem Zement Austria’s technical director Florian Salzer said "It fills us with particular pride that we were able to fill the new department with talented employees from our own company. This clearly underlines the potential that exists in our team and emphasises the extensive expertise that we have built up. We are also pleased that the department management is in the competent hands of Christine Gröll, who brings an incomparable mix of research drive and practical experience.”

US: Block-Lite plans to install a system to cure concrete blocks using direct air capture (DAC)-sourced CO₂ at its Flagstaff, Arizona, concrete block plant. The upgrade will implement CarbonBuilt’s low-CO₂ concrete production technology and AirCapture’s modular DAC technology, across five or six capture units. Direct air capture will thus remove 500 – 600t/yr of CO₂ from the atmosphere, while process changes will reduce CO₂ emissions from the Flagstaff plant by over 2000t/yr. The project has attracted fundraising from the 4 Corners Carbon Coalition (4CCC), with a goal of US$50,000. The Arizon Daily Sun newspaper has reported that Block-Lite plans to supply its first shipment of low-CO₂ blocks to a 50-home development by Habitat for Humanity in Flagstaff.

Europe: The EU has enacted the implementing regulation for the carbon border adjustment mechanism (CBAM) under its emissions trading scheme (ETS). Under the CBAM, importers of cement to the EU will eventually pay taxes for its embedded CO₂ emissions, equivalent to those levied against EU-based producers. Importers must begin to collect emissions data from 1 October 2023, and submit a report for the fourth quarter of 2023 to EU authorities by 31 January 2024. No financial adjustment will yet be payable during the transition period to full CBAM implementation from the start of 2026.

The Asset newspaper has reported that dedicated IT tools and training materials for importers affected by the CBAM are currently in development, according to the European Commission.

Mexico: Cemex has updated its sustainability-linked financing framework in line with its latest emissions reduction targets of 475kg/t of CO₂ per tonne of cementitious material. Under the new framework, Cemex will issue up to US$350m-worth of sustainability-linked bonds on the Mexican Stock Exchange. The group plans to use the funds to refinance debt, as well as for ‘general corporate purposes.’ It aims to acheive 85% sustainability-linked financing by 2030.

Cemex said "The proceeds will be used exclusively for eligible green projects in pollution prevention and control, renewable energy, energy efficiency, clean transportation, sustainable water and wastewater management, production technologies and processes adapted to the circular economy and/or eco-efficient products.”

US: Heat Battery developer Rondo Energy has concluded a financing round with US$60m raised in investments, Renewables Now News has reported. Investors included Siam Cement Group and Titan Cement Group, as well as Breakthrough Energy Ventures, Energy Impact Partners, the Climate Innovation Fund, Rio Tinto, SABIC, Aramco Ventures, SDCL Energy Efficiency Income Trust and John Doerr. Rondo Energy’s Heat Battery is a means of connecting cement plants and other industrial facilities to a constant supply of electricity ultimately derived from renewable energy sources.

CEO John O'Donnell said “Our Strategic Investor Advisory Board will help Rondo focus on the simplest, fastest ways to power their operations with low-cost clean energy and shape our priorities for ongoing research and development.”
