Germany: The Catch4Climate project has moved into the planning stage of its oxyfuel pilot plant at the Mergelstetten cement plant. The group, comprising Buzzi Unicem’s subsidiary Dyckerhoff, HeidelbergCement, Schwenk Zement and Vicat, signed a letter of intent with the state’s prime minister and transport minister in Stuttgart in mid-November 2020.

The consortium intends to build and operate its own demonstration plant on a semi-industrial scale, to use the oxyfuel process to capture CO₂. In the future, the captured CO₂ will be used to produce so-called ‘reFuels’, climate-neutral synthetic fuels such as kerosene for air traffic, with the help of renewable electrical energy.

The cement producers formed CI4C – Cement Innovation for Climate in late 2019. The aim of the Catch4Climate project is to create the basis for a large-scale application of CO₂ capture technologies in cement plants enabling the later use of CO₂ as a raw material in other processes such as a carbon capture and utilisation/storage.

Germany: Dyckerhoff has reopened a railway siding at its integrated Amöneburg cement plant. The additional transport link joins road and water connections at the site. The company said that reusing the railway siding made sense given low water levels in the River Rhine, that made parts of the waterway unnavigable in 2018, as well as adding a sustainable transport route. The railway tracks at the site have not been used actively since the mid-2000s. The cement producer has repaired the tracks on its site and a related signalling system.

Ukraine: The Interdepartmental Commission for International Trade (ICIT) has pursued a complaint by multiple domestic cement producers including Buzzi-Unicem subsidiary Dyckerhoff, HeidelbergCement subsidiary Kryvyi Rih Cement and CRH subsidiary Podilsky Cement in opening an investigation into imports of cement from Turkey. The Uriadovy Kurier newspaper has reported that, on its preliminary assessment, the ICIT deemed the complaint to provide “sufficiently substantiated evidence on the basis of which it can be considered that the importation of cement into Ukraine originating in Turkey could be at dumped prices, the margin cannot be considered minimal and the import volumes are not insignificant in accordance with the law.” It added, “The complaint also provides sufficiently substantiated evidence that imports were made to an extent and under conditions such that they may cause material injury to the domestic producer.”

Germany: Buzzi-Unicem subsidiary Dyckerhoff has paved the 3700m2 of road outside the limestone quarry at its 0.4Mt/yr integrated Geseke plant in North Rhine-Westphalia. It used a concrete blend containing PKZ Doppel N cement produced at the Geseke plant, which it applied to a thickness of 20cm over an asphalt base. Dyckerhoff made the decision to pave the road ‘to minimise dust emissions, especially in prolonged dry spells.’ It says the concrete’s low water content and good compression give the road a strength rating of 50N/mm2.

Germany: Four of Europe’s leading cement producers have partnered to found and operate a 100% carbon capture and storage (CCS) plant at Schwenk Zement’s 1.0Mt/yr Mergelstetten plant in southern Germany. HeidelbergCement has announced that the catch4climate project will enter operation in 2020.

US: Cemex is looking to sell its majority stake in the Kosmos Cement plant at Louisville in Kentucky. Sources quoted by the El Financiero newspaper said that the integrated plant could be valued as high as US$750m. Cemex is working with Bank of America and Citigroup on the potential sale. Buzzi Unicem, through its subsidiary Dyckerhoff, owns the remaining stake in the plant. Cemex’s decision to try and sell the plant follows falling sales and profits for the Mexican building materials producer so far in 2019.

Russia: Buzzi Unicem has formed its total 8.1Mt/yr Russian operations into a limited liability company called SLK Cement. The name combines the first letters of the names of cities where its plants are located, namely Sukhoi Log and Korkino. Andrey Immoreev, chief executive officer (CEO) of Dyckerhoff Cement in Russia, said that the rebranding ‘emphasises the importance of the Russian market in the company’s plans.’ Buzzi Unicem continues to trade as Dyckerhoff in its Central and Eastern European production areas.

Germany: Dyckerhoff has installed a solid recovered fuel processer at Germany’s largest capacity cement plant in Deuna, Thuringia. Lindner has stated that it installed the production line, consisting of four Lindner shredders and developed by B+T Group, during the overhaul phase without disruption to Deuna’s 2.4Mt/yr capacity output. B+T will provide a constant supply of mostly pre-sorted non-recyclable post-consumer packaging and rubber and textile waste. The fuel will feed Deuna’s rotary kilns with sustainably-sourced energy at a rate of 720t/day.

Russia/Ukraine: Dyckerhoff cement plants in Russia and Ukraine have gained OHSAS 18001 or ISO 45001 certification in occupational safety. The OHSAS 18001 and ISO 45001 standards provide for a safe and healthy workplace environment and set forth guidelines for continually identifying and controlling health and safety risks, reducing accidents and improving overall performance.

Germany: Dyckerhoff is supplying 12,000t of CEM III/A 32.5 N-LH cement to Frankfurt Airport for the production of underwater concrete. The airport is building a new terminal and the construction pit for the floor slab is deeper than the groundwater level, hence the floor slab must be concreted underwater.

The construction pit has a size of almost 66,000m² with excavation carried out in dry conditions to a depth of 5.5m to the groundwater table. Then a further 8 -11m was excavated in wet conditions using industrial divers. The excavation pit has been prepared in sections and then concreted by the divers resulting in short sections. The quantities of cement to be delivered by Dyckerhoff also fluctuate considerably, with sometimes 20 silo trucks/day leaving the Dyckerhoff plant in Wiesbaden. Deliveries started in March 2019.

Around 40,000m³ of concrete has been produced by Sehring Beton, using a mobile mixing plant directly on site. The construction work is being carried out by the Arge Ingenieurbau Baugrube T3, which consists of the two companies Adam Hörnig Bau and Bickhardt Bau.
