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.

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."

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: 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.
