It previously said it was close to commissioning the grinding mill and despatch unit for the line in August 2021.

Spain: Cementos Cosmos plans to scale down the production of clinker at its Córdoba cement plant as a result as the high cost of electricity. The Cordoba Day newspaper has reported that parent company Votorantim Cimentos said that clinker grinding operations at the site will continue to ensure a sufficient cement supply in the region.

The Córdoba cement plant employs 48 people. The company is currently negotiating the situation and the scope of its impacts with the workforce.

Nepal: Udayapur Cement has commenced a US$4.2m upgrade and capacity expansion of its cement plant at Jaljale. The work includes replacing the shell of its 20m rotary kiln by the end of February 2021 and installing a reinforcement suspension preheater system, according to the Kathmandu Post newspaper. It will expand the plant’s capacity by 38% to 0.4Mt/yr from 0.29t/yr. The plant’s current equipment dates to 1988. Company spokesperson Laxman Pokharel said "Since the machines are old, we face frequent problems." He added that this has led to increased costs.

The Nepal government has agreed to loan Udayapur Cement US$34.4m, 80% of the project’s budget.

Russia: Kavkazcement has announced that it will use its Kavkaz cement plant's annual shutdown in the winter of 2021 - 2022 to upgrade the plant's raw materials mills and kiln lines. The Eurocement subsidiary plans to spend US$7.14m on the work, which also includes the replacement of burners in kilns 2 and 4 and the installation of new drying drums, compressors and electrostatic precipitators. The upgrade will increase the 3Mt/yr plant's cement capacity by 10% and its clinker capacity by 30%. Managing director Vladimir Sokoltsov said that the upgrade focused on minimising the plant's environmental impacts.

Sokoltsov said “We will prepare the plant for the high construction season in April 2022. Our products are used in the construction of the largest industrial, transport and municipalinfrastructure in southern Russia." He continued "We understand that the quality of life of a large number of people depends on the pace of our work.”

South Africa: Sephaku Cement has reported a second unexpected kiln stoppage at its integrated Aganang plant in Lichtenburg. It attributed the second delay on the need for a repair to the inside of the kiln. The second stoppage started on 16 October 2021 and was expected to be completed by 26 October 2021. Previously, the kiln was stopped from 30 September 2021 to 6 October 2021 due to preheater refractory material damage caused by a corrosive element in one of the raw materials being used. The producer said that the raw material was subsequently replaced with an alternative option. The subsidiary of Nigeria-based Dangote Cement said that the outages were expected to reduce its sales volumes.

Finland: The VTT Technical Research Centre of Finland and Finnsementti have revealed work on the Decarbonate project to test a 12m electrically-heated rotary kiln. Other partners on the initiative included Nordkalk and UPM. Precalcination was tested as well as the projection of quick lime. The eventual goal is to use electricity from renewable sources to power the kiln and then capture the CO₂ released for utilisation.

The Decarbonate project has been exploring CO₂ capture and utilisation concepts that can be commercialised. It has run for two years since late 2019 and has funding of Euro1.2m. It has also looked at oxyfuel and electrolysis experiments.

India: Shree Cement has hired FLSmidth to supply a 11,5000t/day kiln line for its planned Nawalgarh, Rajasthan, cement plant. The line will consist of a six-stage preheater and a three-support kiln. The supplier will also deliver an OK vertical roller mill, which it says has a 5 – 10% lower energy consumption than a standard vertical roller mill. The project focuses on sustainable productivity and emissions control. Shree Cement has opted for JetFlex burners to give the lowest possible nitrous oxide emissions for various fuel types.

Shree Cement managing director Prashant Bangur said “Based on the experience of working with FLSmidth on the installation of a 9,000t/day pyro system at the Raipur, Chhattisgarh, cement plant earlier this year, we felt confident about approaching Carsten Riisberg Lund and his team regarding the Rajasthan project.” He added “Being recognised as a Sustainability Champion by the World Economic Forum is a testament of our emphasis on sustainability at every stage of our operations. The new line will push that agenda even further in terms of lowering the benchmarks on energy consumption and emissions, and thereby reducing our environmental footprint.”

FLSmidth also supplied a second OK mill for Shree Cement’s operations in Kolkata, West Bengal.
