FLSmidth forms ECoClay partnership to electrify clay calcination for cement production 27 April 2022
Denmark: FLSmidth has formed a partnership called ECoClay to develop and commercialise the technology needed to electrify the calcination of clay used in cement production. The partners include the Danish Technological Institute, US-based industrial heating specialist Rondo Energy, France-based Vicat, Colombia-based Cementos Argos and the Technical University of Denmark. The project is partly funded by the Energy Technology Development and Demonstration Program (EUDP) under the Danish Energy Agency.
The use of calcined clay in cement production allows cement producers to replace up to 30% of limestone-based clinker, resulting in up to 40% lower CO₂/t in cement produced. By electrifying the process, ideally powered by renewable sources, the ECoClay partnership expects to further reduce emissions by 10% at more uniform conditions that allow processing of a broader range of raw clays.
Based on the shared research and tests on high-temperature electric heat generation, storage solutions and renewable grid integration, the ECoClay partnership will build a pilot plant at FLSmidth’s research and development centre in Denmark. The consortium will seek to demonstrate how the ECoClay process is superior to the conventional combustion processes, has a smaller physical footprint on site and significantly lower emissions of air pollutants. According to the project plan, the ECoClay partners expect to be able to commence construction of the first full-scale electric clay calcination installation by the end of 2025.
Russia: Eurocement has started an initiative to reduce its reliance on spare parts purchased from outside of the country. The programme is designed to start a phased transition to in-house production of components. One of the first examples of the scheme has been the development and installation of a clutch for a mill at the Sengileevsky cement plant.
The cement producer hopes to source at least 90% of the parts it requires domestically. At present it says that around 30% of the equipment used in the local cement sector is imported. The estimated economic effect will be around Euro14m.
The company has also announced an unscheduled indexation of staff wages to over 7000 workers at 16 cement plants. Indexing of wages is typically used to compensate for inflation. Other measures have also included food support. Vyacheslav Shmatov, the general director of Eurocement, said ““We have decided to increase our support measures for our employees during this difficult time in order to strengthen our work teams. Eurocement is, first of all, people, so the company will continue to take care of its employees.”
International economic sanctions were implemented upon Russia by European and North American countries in response to its invasion of Ukraine in February 2022.
Cement Hranice increases sales and profit 26 April 2022
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."
Cemex turns flue gases into carbon nanomaterials 26 April 2022
Mexico: Cemex has reported its successful completion of laboratory tests aimed at converting CO2 emitted by cement kilns into carbon nanomaterials. The producer said that it was able to turn 50% of available carbon in a flue gas stream into nanomaterials. Possible industrial uses for carbon nanomaterials include in building materials, biomedicines, electronics and agriculture. Cemex says that its next step will be to scale the technology for a cement plant pilot study.
CEO Fernando Gonzalez said “This breakthrough technology is significant for Cemex, not only because it offers the potential to commercialise carbon emissions, but because it demonstrates the value of our Smart Innovation platform. The path to carbon neutrality will be built with innovation, and we remain committed to being at the forefront in developing new circular technologies and processes.”
Cameroon government bans cement exports from East Region 26 April 2022
Cameroon: The government has enacted a ban on the export of cement, along with other commodities including oil and grain, from East Region. The Journal du Cameroun newspaper has reported that the impacts of the Russian invasion of Ukraine have exacerbated a difficult supply situation of the basic commodities in the region, dating to the beginning of the Covid-19 outbreak in the country in March 2020.
The East Region borders the Central African Republic and Congo. It has no cement plants of its own.
India: The Directorate General of Mines Safety (DGMS) has named Ambuja Cements’ Rabriyawas cement plant as winner of its National Safety Award (Mines). Its winning initiatives include its Behaviour Based Safety training programme and Reward & Recognition employee engagement programme. Ambuja Cements said that the award confirms that Ambuja's Zero Harm policy has borne fruit.
Rajkot cement plant explosion kills three 26 April 2022

Zimbabwe: UK-based Associated International Cement Limited (ACIL) has reportedly rejected an offer for its 76% stake in Lafarge Zimbabwe. Lafarge Zimbabwe company secretary Faithful Sithole said that the parent company is still assessing offers received for the stake. The NewZimbabwe newspaper has reported that the declined offer may have come from China-based Huaxin Cement.
India: Bharathi Cement plans to build a US$17m automated terminal and packaging plant at Coimbatore, Tamil Nadu. United News of India has reported that the facility will package the company’s bagged and bulk cement and supply the South West Tamil Nadu and Kerala markets.
On 23 April 2022, the subsidiary of France-based Vicat despatched its first rake of cement aboard custom-built tank and box container cars to Coimbatore from its Kadapa, Andhra Pradesh, cement plant. Vicat’s India CEO Anoop Kumar Saxena said that the first-of-its method of bulk cement transportation will reduce the company’s logistics costs and carbon emission and increase the service level for customers.
Holcim US joins Carbon Capture Coalition 25 April 2022
US: Holcim US has become the first cement producer member of the Great Plains Institute’s Carbon Capture Coalition. The coalition’s 78 participating members and 23 observer organisations collaborate to build federal policy support for economy-wide, commercial-scale deployment of carbon capture and related technologies. Holcim US is currently assessing the viability of commercial-scale carbon capture, with two studies underway, at its Portland cement plant in Colorado and its Ste. Genevieve cement plant in Missouri.
Region head North America Toufic Tabbara said “Being at the forefront of developing low carbon solutions requires continuous innovative thinking and partnerships. Our efforts are most effective when we can align and join forces with other companies and organisations across industries who share this same commitment. We are proud to be part of an organisation that is similarly focused toward more efficient, innovative and sustainable practices.”
