Uzbekistan: Bekabadcement is carrying out a 'large-scale' upgrade to its 0.7Mt/yr Bekabadcement plant in Tashkent Region. The producer said that the upgrade involves a 20% capacity expansion of the plant's production line to 2500t/day. Austria-based Unitherm CemCon supplied burners for the upgraded line, while China-based Beijing Triumph International Engineering supplied heat exchanger components and a KC 4.1-0955 cooler. The upgrade also involves the installation of new kiln lining, and will transition the plant's cement production from wet to dry process. Germany-based Christian Pfeiffer previously upgraded the Bekabad cement plant's grinding unit in April 2023.

General director Vasily Korobkin "We see that (parent company) United Cement Group (UCG) is interested in the modernisation and development of the enterprise. The group adheres to international standards, so all plans for the development of the plant are built accordingly." He concluded "We expect to become a modern and successful enterprise in Uzbekistan which is capable of becoming a major player in the cement industry of Central Asia.”

Egypt: Heidelberg Materials subsidiary Suez Cement has invested US$16m in upgrading its operations towards increased alternative fuel (AF) use since 2010.

UAE: Holcim subsidiary Lafarge Emirates Cement (LEC) has begun construction of a 10MW waste heat recovery (WHR) plant at its 3.2Mt/yr Fujairah cement plant. Supplier Engie Solutions says that it expects to commission the installation later in 2023. Trade Arabia News has reported that the equipment is based on a closed-loop organic Rankine cycle and will eliminate 29,000t/yr of CO₂ - 28% of the Fujairah cement plant's energy-related CO₂ emissions.

LEC general manager Olivier Milhaud said "Engie’s energy-as-a-service model means guaranteed energy savings and higher reliability and resilience, with no capital outlay and no need for additional staff." He continued "We are fully committed to the UAE’s sustainability goals, including the 2050 Net Zero vision."

Türkiye: Italy-based CTP Team says it is currently installing a new waste heat recovery (WHR) system at Medcem Çimento’s Mersin plant. Its contribution to the construction of a new production line at the site includes installing an organic rankine cycle-based (ORC) 10.5Mwe WHR system and three new process fabric filters for the kiln and raw mill, coal mill and cement mills. The new line is expected to be commissioned in 2024.

India: Ambuja Cements has placed orders with equipment suppliers for an 8Mt/yr clinker capacity expansion across two of its cement plants. The plants in question are the 2.9Mt/yr Bhatapara cement plant in Chhattisgarh and the 4.5Mt/yr Maratha cement plant in Maharashtra. Ambuja Cements will also build 42MW-worth of waste heat recovery (WHR) power capacity. The new cement capacity will be able to operate on renewable energy and use 50% alternative fuel (AF). As such, upon completion of the project, the plants will together produce 14Mt/yr of Ambuja Cements' reduced-CO₂ Blended Green Cement. The producer will fund the work through internal accruals, and expects to complete it in May 2025.

CEO Ajay Kapur said "These brownfield expansion projects are part of our strategy to double our production capacity over the next five years from the current capacity of 67.5Mt/yr. Our ongoing investments in capacity expansion and sustainability will enable us to achieve our long-term objectives, as we remain committed to delivering sustainable growth and value to our stakeholders."

France: Ciments Calcia has announced an investment of Euro86m to further decarbonise cement production at its integrated Beaucaire plant. The subsidiary of Germany-based Heidelberg Materials has allocated a total of Euro600m towards reducing CO₂ emissions from all of its operations in the country in response to a government initiative, according to The Tribune newspaper.

The current funding follows a spend of just under Euro7m on upgrades at the site, including installing a new clinker cooler that will allow for greater recovery of waste heat, and the addition of a new computer control system. Following this work, the single production line plant was restarted in early April 2023.

The next stage of investment has started with a feasibility study. If successful, a tendering process could start in the second half of 2023 with work planned to start in 2025. The company intends to renovate the plant’s electricity network, modernise the production line with a preheater and a pre-crusher and make further changes to target an alternative fuels thermal substitution rate of 75%. A third stage, involving carbon capture and utilisation and/or storage, is tentatively planned to start in 2030.

Ireland/UK: A six-month feasibility study conducted by Mannok at its Derrylin plant, in conjunction with Catagen, has found a number of ways that the cement producer can reduce its CO₂ emissions. Using Catagen’s HGEN renewable hydrogen generator with waste heat recovery could potentially decrease the cement plant’s annual CO₂ emissions by 7%. In addition the study found that using biohydrogen generation from waste biomass could generate larger volumes of hydrogen with less renewable energy required, compared to electrolytic hydrogen generation. Using Catagen’s BIOHGEN process in this way could minimise carbon intensity by a further 18%. A combined group of engineers from Mannok and Catagen worked on the project.

Kevin Lunney, operations director at Mannok, said “We are very excited to be working with the Catagen team, who have demonstrated a deep level of technical ability and competency during the feasibility work. I have no doubt that Mannok will derive significant value from the work already completed, with many new opportunities for collaboration now presenting that we would not have considered before. Achieving Net Zero is now the primary goal for our business and I expect Catagen will play a significant role in our achieving that goal, which we expect will have major benefits for the sector overall.”

In early April 2023 Mannok revealed that it had secured funding from the UK Government Green Energy Scheme to support its energy transformation programme. The first phase of the initiative, which the funding will support, is the generation of onsite green hydrogen to replace the use of diesel in over 70% of the company’s 150 heavy-goods truck fleet.

Belfast-based Catagen started as a testing company providing emissions data to the automotive sector. It has started working in other industrial sectors - such as cement, glass and steel in Europe and the US – as part of its ClimaHtech product range.
