Qatar: Qatar witnessed robust month-on-month cement production growth during September 2020 as the country scaled back its Covid-19 restrictions. Cement production increased by 9.1%. Cement was one of a number of sectors to buck a wider trend of a continued industrial slowdown, according to the Planning and Statistics Authority (PSA). However, the volume of cement produced was 3.1% lower than in September 2019.

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.

US: The US Environmental Protection Agency (EPA) has awarded its 2020 Energy Star® certification to Buzzi Unicem USA plants in Chattanooga, Tennessee and in Festus, Missouri. This certification is awarded to a facility for superior energy performance in comparison to similar plants. This marks the 12th consecutive year that the Chattanooga and Festus plants have received certification.

In order to qualify for Energy Star® recognition, cement plants must score at least 75 on the Energy Performance Indicator (EPI) system used by the EPA to measure energy efficiency. In addition, the plant must have a satisfactory environmental compliance record for the past three years. Receipt of the Energy Star certification means these two plants perform in the top 25% of similar facilities in the US.

France: HeidelbergCement’s subsidiary Ciments Calcia plans to stop clinker production at two plants as part of a Euro400m investment and reorganisation programme for several of its sites in France. Around Euro300m of this will be spent at the integrated Airvault cement plant. The company also intends to: convert its integrated Gargenville cement plant into a grinding plant and shut down its kiln systems and quarry operations; convert its integrated Cruas white cement plant into an automated cement terminal for the distribution of white cement; and adapt the organisation at its French headquarters at Guerville. The plan will cut 162 jobs and create 20 new ones.

“As part of our global business excellence initiative, we intend to further optimise effectiveness, processes and structures of our French sites,” said Dominik von Achten, chairman of the managing board of HeidelbergCement. “We want to considerably speed up the modernisation of our plants in order to enhance our performance in France, while ensuring alignment with the goals of the Paris agreement. This is why we focus our initiatives on the main CO₂-emitting plants in France.”

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.

Mozambique: China-based Sino Energy has signed a non-legally-binding memorandum of understanding with Hong Kong Construction Group in which it agreed to buy a 65% stake in a 0.4Mt/yr cement plant in Northern Pemba City, Cabo Delgado Province. Sino Energy will conduct due diligence and further negotiations on the proposed acquisition over the next four months. No value for the proposed purchase has been disclosed.

Sino Energy’s main business is manufacturing and selling of casual footwear, apparel and related accessories in mainland China. The company is also developing petrol station operations.

Cameroon: Dangote Cement’s subsidiary in Cameroon estimates that it had a market share of 39% in the first nine months of 2020. It reckons the total cement market in the country was over 2.6Mt in the same period and that it sold around 1Mt, according to the Ecofin Agency. It said that the market was mainly driven by individual construction projects and public housing estates. In February 2020 the subsidiary of the Nigeria-based company said it planned to do better business in 2020 by focusing on the construction sites of stadiums, roads, hotels and other construction projects in preparation for the 2021 Africa Cup of Nations, postponed to 2022.

The cement producer operates a 1.5Mt/yr cement grinding plant in Douala, with a dedicated jetty for offloading clinker that opened in 2015.

India: ACC plans to sell its National Limestone Company subsidiary to Ghadiya Group for around US$2.5m. National Limestone Company holds mining leases for limestone in the state of Rajasthan. Ghadiya Group operates in the construction and mining sector.
