Namibia: Ohorongo Cement Namibia has supplied 3000m³ of cement to the site of NamPower's upcoming Sekelduin power plant in Swakopmund. Ohorongo Cement used 730t of its CEMIR cement, which contains 30% fly ash, combined with an additional 30% fly ash in the concrete mixer. The producer said that the extra ash increases the finished product's density, reducing permeability.

Ohorongo Cement said that the project is 'near completion,' having begun in mid-2021.

Australia: The Australian Competition and Consumer Commission (ACCC) has called for public comment on Switzerland-based Sika's proposed acquisition of Germany-based fellow construction chemicals producer MBCC Group. The commission has raised 'preliminary concerns' over the possible competition impacts of Sika obtaining an 80% Australian market share as a result of the deal.

Sika group responded to the ACCC's concerns with an offer of an undertaking to divest MBCC Group's entire Australia and New Zealand business.

Belgium: The EU Innovation Fund has awarded Euro4.5m to a consortium consisting of Prefer, gas provider Fluxys Belgium, lime producer Lhoist and carbonation technology developer Orbix. The collaborators are working on a project called CO2ncrEAT. The project will carbonate steel sector by-products with captured CO₂ from Lhoist's Hermalle lime plant to produce alternative building materials. CO2ncrEAT will be the first project to employ Orbix's innovative technique for the purpose. Fluxys Belgium's pipeline technology will convey the Hermalle plant's emissions over a distance of 2km to a Prefer concrete blocks plant.

The consortium said that it will use 12,000t/yr of CO₂ to produce 100,000t/yr of reduced-CO₂ concrete blocks. The use of alternative raw materials in the blocks will further reduce their carbon footprint by 8000t/yr.

Prefer managing director Raphaël Grimont said “As market leader, we must ensure the sustainability of our business by offering innovative and eco-friendly products to our customers. With the CO2ncrEAT project, our building materials will be produced through a sustainable and efficient process and based on local, circular raw materials. The Prefer masonry block of tomorrow will retain all the advantages of the traditional block, with the difference that it will benefit from a negative carbon footprint. We are proud to develop this exceptional project together with key industrial partners, while benefitting from the trust of the European, Belgian and Walloon authorities.”

Austria: Lafarge Austria and Perlmooser Beton will operate under the new name Holcim Austria from May 2023. Both companies have been part of Holcim Group since 2015. The rebranding exercise follows the renaming of LafargeHolcim as Holcim that took place in mid-2021.

Lafarge Austria operates two cement plants, at Mannersdorf and Retznei respectively, with a total production capacity of 1.6Mt/yr. Its headquarters is in Vienna. The company employs around 250 people.

Estonia: The Estonian Competition Authority has granted permission to Schwenk Eesti to gain a majority stake in ready-mix concrete producer Betoonimeister. Baltic Business Daily News has reported that Betoonimeister's six ready-mix concrete batching plants are located in Tallinn, Tartu, Johvi, Tapa and Parnu.
