Mexico: Cemex and Coolbrook have signed a memorandum of understanding to test technology to electrify the cement kiln heating process. Coolbrook says that its Roto Dynamic Heater (RDH) technology can heat a cement kiln to 1700°C using electrical power. If generated from renewable sources this could potentially remove around 45% of the carbon emissions in cement production that normally arise from the use of fossil fuels. The companies expect the technology to be ready for commercial use at an industrial scale in 2024. They will jointly evaluate the best production site to test and develop this technology.

Ilpo Kuokkanen, the executive chair of Coolbrook, said "Coolbrook has set a target to build a comprehensive ecosystem around its revolutionary technology and to test its use in as many industrial processes as fast as possible. Together with Cemex, we can bring the technology to cement production and achieve significant emission reductions in one of the most energy and CO₂-intensive industrial processes.”

Finland-based Coolbrook is a technology and engineering company that is developing processes to replace the burning of fossil fuels in major industrial sectors. Its RDH has potential applications in cement, steel and chemical production process. Its Roto Dynamic Reactor (RDR) is intended to eliminate CO₂ emissions from the steam cracking process used in the production of plastic.

Russia: SibCem subsidiary Angarskcement has restarted kiln four at its plant in Angarsk after a decade of inactivity. The kiln was last used in 2010. The decision to restart the kiln was made in 2021 due to growing demand for building materials in the Irkutsk region and an increase in cement sales. Kiln four was first lit in 1960 and was later upgraded in the early 1980s. It has a clinker production capacity of 720t/day. All four kilns are now running at the cement plant.

Russia: Spasskcement has run kiln two at its plant in Primorye continuously for a record of 330 days. This has beaten the previous best runtime of 324 days set in 2021. The kiln has now been shut down for scheduled repairs including replacing refractory lining and maintenance work on mechanical and electrical equipment. Work is scheduled to be completed by early May 2022.

Tanzania: Tanga Cement’s full-year results show a 9% year-on-year rise in sales to US$99.5m in 2021 from US$91.7m in 2020. Its net profit was US$1.5m, as against a US$903,000 loss in 2020.

The Kenyan Wall Street newspaper has reported that the company replaced a kiln shell at its Tanga cement plant and outsourced mining operations at its quarry during the year.

Belgium: CBR has successfully completed an upgrade of systems connected to the kiln of its 0.8Mt/yr Antoing cement plant. The company says that it has modernised the kiln gas cycle, reducing the plant’s power consumption by 2.5%.

The Antoing cement plant previously underwent a capacity expansion and alternative fuels (AF) substitution-increasing upgrade to its kiln line in late 2020.

Saudi Arabia: Yamama Cement has signed a US$443m financing agreement with Saudi National Bank (SNB). The company plans to invest the funds in its relocation of a 10,000t/day kiln line to its Northern Halal, Al Kharj, plant from the site of its former plant in Riyadh. This will help towards its aim of increasing the Northern Halal plant’s capacity to 30,000t/day by 2025. The loan consists of US$213m in long-term financing for a period of eight years, US$150m in refinancing of the long-term funding for a duration of four years and US$80m in short-term financing for one year.

France: The European Commission (EC) has awarded funding under its Innovation Fund 2021 for CRH subsidiary Eqiom’s upgrade to its Lumbres, Hauts-de-France, cement plant. The work includes the replacement of a kiln and the installation of a carbon capture, utilisation and storage (CCUS) system at the plant, in collaboration with Air Liquide. The producer says that the project is one of seven selected under the EC’s K6 programme of innovation funding in line with the EU Green Deal.

India: Shree Cement has commenced commercial production of clinker with the newly commissioned Kiln 3 of its Raipur cement plant in Chhattisgarh. The kiln has a production capacity of 4Mt/yr.

India: Shree Cement has fired up the kiln of a new clinker line at its Raipur cement plant in Baloda Bazar, Chhattisgarh. The Business Standard newspaper has reported that the company funded the project, involving the reactivation of the Raipur plant’s Kiln 3, from its internal accruals. It has also installed a new waste heat recovery (WHR) plant alongside the kiln. The line will augment Shree Cement’s supply of clinker to its grinding plants in Eastern India. It hopes thereby to contribute to growth and development in Chhattisgarh and beyond.

India: Ghohari Cement says that it has ignited the new kiln of its Laxmipur cement plant in Dang District. Shivam Cement assistant engineer Nilesh Chouhan said that kiln inlet temperature monitoring was underway on 18 February 2022.
