Morocco: Holcim subsidiary LafargeHolcim Maroc has released information about its 1.6Mt/yr Agadir cement plant in Souss-Massa Region. The producer invested US$299m in the plant’s construction and it has been operational since late 2021. The plant is highly automated in line with Holcim’s Plants of Tomorrow strategy. It will run off wind power from 2023, and also uses alternative fuel (AF). 200 people work at the plant.

In conjunction with its work in setting up the new cement plant, LafargeHolcim Maroc developed drinking water networks in the surrounding area, including the construction of three solar-powered water towers.

Germany: HeidelbergCement has joined EPEA’s Heidelberg Circular City Building Material Registry pilot project. The initiative uses EMEA’s Urban Mining Screening digital registry, which is able to estimate the composition of buildings based on building data. HeidelbergCement says that it will enable it to source construction and demolition waste for circular economic use in building materials production. This will support its ReConcrete 360° recycled concrete CO₂ reincorporation project, among other projects. The initiative will turn Heidelberg into Europe’s first Circular City.

“Full circular economy and sustainable construction are central elements of our climate strategy,” said HeidelbergCement chair Dominik von Achten. “We are focusing on the life cycle assessment of our product concrete, including the processing of demolished concrete, and returning it to the construction cycle. By 2030, we want to offer circular alternatives for half of our concrete products.” Von Achten concluded “Together with the city of Heidelberg, also a pioneer in the area of climate protection, we want to use the Circular City project to demonstrate the enormous potential of concrete recycling for future urban construction.” 


UK: Karbonite UK has developed a new supplementary cementitious material consisting of mineral feedstock, geopolymers and waste biomass. The process also involves CO₂ sequestration and liquid-infused CO₂ absorption within the mineral structure. The material, called Karbonite, is activated at 750 – 850°C, releasing water, which is captured for recycling. Its CO2 emissions are 2.7kg/t, according to Karbonite UK. The developer says that Karbonite ground with 50% clinker yields a cement of equal compressive strength to ordinary Portland cement (OPC).

Karbonite UK is currently preparing a final report on the product for a major cement producer.

Managing director Rajeev Sood said “Karbonite offers a wealth of potential to an industry targeting net zero. We are excited to talk to cement and concrete producers about how they could integrate Karbonite technology into their existing process.”

Uzbekistan: QuvasoyCement has installed Denair Energy Saving Technology (Shanghai)’s DV 315 compressors at its Fergana cement plant. The cement producer says that the new compressors increase performance by 95% compared to previous equipment. It predicts cost savings of US$25,100/yr as a result of the upgrade.

Austria: RHI Magnesita’s customers can now rely on Environmental Indicators on all of its products’ Technical Data Sheets to check their CO₂ emissions. The indicators state the CO₂ equivalent emissions per tonne of each product. The supplier calculated the figures in line with ISO standards under on-going external supervision.

Chief sustainability officer Gustavo Franco said “One of RHI Magnesita’s main targets is to significantly reduce emissions over the next few decades, with the long-term goal of achieving net-zero operations in all areas of the company. It is clear that a solid basis for sustainable decisions and developments can only be achieved by creating a valid audited database.”
