US: Germany-based Heidelberg Materials has entered into a definitive purchase agreement to acquire The SEFA Group Inc., the largest fly ash recycling company in the US. Based in Lexington, South Carolina, the operations of The SEFA Group include five business units, five utility partners, 20 locations and more than 500 employees. The group currently supplies quality fly ash to more than 800 concrete plants in 13 states.

Heidelberg Materials said that the reuse of fly ash from energy generation in alternative products such as composite cements enhances its circularity efforts within its value chain by reducing the CO₂ emissions of its cement and concrete. The transaction is anticipated to close in June 2023.

“Fostering circularity by increasing the use of by-products and recycled materials from other industrial sectors is an essential part of our strategy,” said Dr Dominik von Achten, Chairman of the Managing Board at Heidelberg Materials. “Our focus is on rapidly and significantly reducing our CO₂ emissions and The SEFA Group will make an outstanding contribution in this regard to our US business.”

Georgia: Heidelberg Materials has completed the divestment of its joint venture in Georgia. It previously held a 45% state in CaucasusCement Holding BV (CCH), the parent company of HeidelbergCement Georgia Ltd and Terjola Quarry Ltd, Tbilisi.

Heidelberg Materials sold its share to its long-term joint venture partner Cement Invest BV, an investment company that is jointly managed and owned by the Georgian Co-Investment Fund and Hunnewell Partners. The joint venture’s scope included two integrated cement plants, 14 ready-mixed concrete plants and two aggregates plants. The partners agreed to not disclose the financial terms of the transaction.

Heidelberg Materials said that these latest steps reflect its continued simplification of its country portfolio and would help to position the company as front runner on the path to Net Zero and circularity in the building materials industry.

UK: MOF Technologies, a Northern Ireland-based company whose technology efficiently captures CO₂ directly from industrial sources, is rebranding to Nuada. The new name is an ode to the company’s Celtic origins and is inspired by the ancient mythical king, Nuada, whose name means ‘to capture.’

Nuada says that its next-generation ‘heatless’ technology is ‘redefining carbon (CO₂) capture,’ slashing the energy penalty and costs associated with CO₂ capture.

Nuada has combined advanced solid adsorbents, named MOFs, with proven vacuum swing technology to enable the separation of CO₂ from flue gas using pressure instead of heat. This ‘heatless’ system represents a step change in innovation that slashes the energy penalty and cost associated with carbon capture, the main barriers for mass adoption in industry.

The company says that the new branding and direction have come at a critical time as the world is sprinting to decarbonise and mitigate the impacts of climate change. This is particularly the case in hard-to-abate industries like cement production, where carbon capture is essential to reaching Net Zero targets.

Tunisia: Carthage Cement saw a 35% rise in turnover during the first quarter of 2023 to reach US$37.3m. The company explained that the improvement was mainly due to a 64% increase in export turnover, which rose from US$4.0m in the first quarter of 2022 to US$6.5m in the first quarter of 2023. Local turnover was also higher, rising by 30% year-on-year to US$27.6m.
