Germany: CI4C has installed the final modular component of its carbon purification unit (CPU) at the Schwenk Zement plant in Mergelstetten. The unit is 31m long with a cross-section of 5 x 5m, installed using a tandem lift.

The unit completes major construction work at the CO₂ capture pilot project. The CPU will clean and liquefy CO₂-rich exhaust gas from the oxyfuel kiln and processes it to food-grade quality, enabling its reuse in purified form. Final mechanical and electrical works are underway ahead of commissioning in late summer 2025.

European cement producers Buzzi, Dyckerhoff, Heidelberg Materials, Schwenk Zement and Vicat established CI4C in 2019 to implement the catch4climate initiative. The 450t/day clinker line and CPU have been purpose-built at the plant, which has received investment of over €120m, and will be used solely for research and development.

Ukraine: The cost to rebuild Ukraine post-war is projected at US$487bn, according to a report commissioned by the United States Agency for International Development. The report states that to support the reconstruction, Ukraine must produce 15-16Mt/yr of cement for three years, a significant increase from current capacities. Protectionist measures in place since 2019 have restricted cement imports and a decline in production and a shrinking market could lead to an increase in construction costs, according to the Kyiv Independent.

Amid these projections, CRH, which operates three plants in Ukraine, announced in summer 2023 that it aims to purchase two more from Buzzi's subsidiary Dyckerhoff. This deal is valued at €100m, with the company stressing the importance of its investments in Ukrainian cement plants to boost the country’s domestic production to 15Mt/yr, according to Forbes Ukraine. The deal is reportedly under scrutiny by Ukraine's Anti-Monopoly Committee due to market concentration concerns, which could drive up cement prices and overall reconstruction costs.

Serhiy Pylypenko, CEO of the Ukrainian building supplies firm Kovalska, Ukraine’s largest cement user, said “We need more players and to diversify the market instead of making it more compact because the competition is very weak. Market concentration allows uncontrolled pricing and the cost of construction and the cost of recovery to skyrocket."

Germany: Dyckerhoff has launched Dyckerhoff Weiss Blue Star, a pozzolanic white cement CEM IV/A (P) 42.5 R product. It was approved by the German cement association, the VDZ, in mid-June 2023 and is now being manufactured at the Amöneburg plant. The lower CO₂ credentials of the new product have been promoted as it releases around 15% less CO₂ compared to CEM I cements. It is also notable for being a blended white cement.

Italy: Buzzi Unicem reported first-quarter sales of Euro956m in 2023, up by 20% year-on-year from Euro800m in the first quarter of 2022. The producer's cement volumes dropped by 8.8% to 5.8Mt from 6.36Mt. It attributed this to a general slowdown of the construction sector across its markets. Local low demand from the residential market and adverse weather compounded the regional sales contraction in Central Europe. On the other hand, the group recorded volumes growth in Mexico and Russia and stability in Brazil. Both Mexico and Brazil produced revenues growth, while Buzzi Unicem's revenues fell in Russia due to the effect of the appreciation of the ruble against the comparison period in 2022, when the start of the on-going Russian invasion of Ukraine devalued it.

Overall, the group expects to 'easily' match its 2022 full-year earnings before interest, taxation, depreciation and amortisation (EBITDA) in 2023. It said that that it could not currently delineate a 'clearly different picture,' but added "The stabilisation of energy prices, albeit at higher levels than in 2022, if confirmed, will allow us to have better visibility on the unfolding of the production costs from spring onwards."

Germany: The Catch4Climate project says it is ready to build an oxyfuel pilot unit at Schwenk Zement’s Mergelstetten plant following approval by the Stuttgart Regional Council. The project comprises Dyckerhoff, Heidelberg Materials, Schwenk Zement and Vicat, and It has set up a research company called CI4C to run it. Over Euro120m will be invested towards building a dedicated 450t/day production line to test the oxyfuel process. Jürgen Thormann, the Technical Managing Director of CI4C, said that this is the first time a so-called ‘pure’ oxyfuel process will be used for CO₂ capture. At a later stage in the project the consortium plans to use the captured CO₂ to produce so-called ‘reFuels’, climate-neutral synthetic fuels such as kerosene for aircraft, with the help of renewable electrical energy. Commissioning of the unit is scheduled for mid-2024.

Italy: Buzzi Unicem recorded a net profit of Euro88.7m in the first half of 2022, down by 58% year-on-year from Euro210m in the first half of 2021. The group said that its recurring profitability worsened across its markets, with the exception of Russia. It also noted ‘substantial stability’ in the Czech Republic. Its consolidated sales, including those of its Brazilian and Mexican businesses, were US$2.41bn, up by 18% from US$2.05bn.

The group recorded cement sales volumes of 14.2Mt, down by 4.1% from 14.8Mt. Volumes fell by 27% in Eastern Europe and by 28% in Italy, but rose by 27% in Central Europe and by 8% in the US. Excluding Russia, the producer’s fuel costs per tonne of cement rose by 8.8% year-on-year to approximately Euro8.80, and its total energy costs rose by 20% year-on-year to Euro234m.

It implemented continued price rises across all markets except Mexico during the half, with the sharpest rises recorded in Italy and Ukraine.

Germany: ThyssenKrupp Industrial Solutions’ Polysius division says that it has been commissioned by Buzzi Unicem, HeidelbergCement, Schwenk Zement and Vicat to build a pure oxyfuel kiln system at the Mergelstetten cement plant as part of the Cement Innovation for Climate (CI4C) project. No dates of the start of construction or final project commissioning of the industrial trial have been disclosed. CI4C was originally formed in 2019.

The Polysius pure oxyfuel process is a new type of clinker production process in which the otherwise normal ambient air is replaced by pure oxygen in the kiln combustion process. One advantage of the technology is that atmospheric nitrogen is eliminated from the clinker burning process leading to much higher concentrations of CO₂ in the exhaust gas compared to a conventional kiln. As such the process aims to concentrate, capture and reuse almost 100% of the CO₂ produced in a cost-effective manner. The medium-term goal is to further process the captured CO₂ with the help of renewable energy into products such as kerosene for air traffic.

Czech Republic: Cement Hranice’s sales rose by 13% year-on-year to US$89m in 2021. Its cement sales rose most sharply in its domestic Czech market, especially in the second half of 2021. As a result, the company increased its net profit for the year by 4% year-on-year to US$25.6m.

Czech News Agency Business News has reported that the company said "The past year was marked by increased demand for cement. Especially at the end of the year, we were forced to reduce our clinker and cement stocks to the lowest possible level, but we still had to slightly reduce deliveries to our customers."

Ukraine: The District Administrative Court of Kiev has dismissed Belarusian Cement Company (BCC)’s claim against the government’s Interdepartmental Commission on International Trade for the cancellation of anti-dumping duties on cement. The duties on imported cement are 57% the value of goods from Belarus, 94% from Moldova and 115% from Russia. The commission introduced the tariffs in late May 2019 and they will expire in late May 2024.

The law firm representing third parties Dyckerhoff Cement Ukraine, HeidelbergCement Ukraine, Ivano-Frankivsk Ukraine and CRH subsidiary Podilsky Cement said "The court recognised the need to protect the violated rights of national cement producers in Ukraine from dumped imports of goods to Ukraine.” It added that the imports had caused ‘significant damage’ to national producers.

Germany: Buzzi Unicem subsidiary Dyckerhoff has received general building inspection approval from the German Institute for Building Technology for the Portland composite cement CEM II / CM (S-LL) produced in the Amöneburg and Deuna factories. It is the first to receive approval to sell this class of cement, which contains both slag and limestone, in Germany.

The use of CEM II / C cements reduces CO₂ emissions from building with cement and concrete due to their lower clinker factor. CEM II / CM (S-LL) emits 39% less CO₂ per tonne of cement compared to CEM I cement. Compared to the current status quo of the binder mix, CEM II / C cements have the potential to reduce CO₂ intensity by 25%.

The CEM II / CM (S-LL) ‘Amöneburg’ and ‘Deuna’ is authorised for use in strength classes 32.5 N, 32.5 R, 42.5 N, 42.5 R, 52.5 N and 52.5 R. It may be used for the production of concrete, reinforced concrete and prestressed concrete in the following exposure classes: X0, XC1 to XC4, XD1 to XD3, XS1 to XS3, XF1, XA1 to XA3, XM1 to XM3.
