Saudi Arabia: Turboden, a subsidiary of Mitsubishi Heavy Industries, has announced its first project in Saudi Arabia — a 13MW organic rankine cycle (ORC) power plant at Riyadh Cement Company. This marks the first ORC plant in the Kingdom and the largest globally.

The plant will capture residual heat from the cement plant's clinker coolers and pre-heaters (2 kilns of 5000t/day each), offering high energy efficiency and eliminating water consumption. Sinoma Energy Conservation serves as the project's engineering, procurement and construction contractor.

General manager Andrea La Gioia said "Turboden is honoured to spearhead this groundbreaking project in collaboration with Riyadh Cement Company. With around 460 ORC plants in 52 countries, 50 in ‘waste’ heat recovery application, our ORC technology represents a game-changer in the global energy landscape, and we are proud to support the Kingdom of Saudi Arabia in its transition towards cleaner, more sustainable energy sources."

Austria: Holcim is set to significantly reduce its carbon footprint with the installation of a new clinker cooler system and a large-scale photovoltaic system at its Mannersdorf cement plant. The clinker cooler project is valued at approximately €10m, and aims to cut heat consumption and reduce CO₂ emissions by 18,000t/yr. Completion is expected in early 2025. The solar project will be fully operational by 2025, and will cover approximately 15% of the plant’s energy needs and reduce CO₂ emissions by an additional 12,700t/yr. 2.7MW of solar panels were erected at the site of the former chimney on the plant’s premises.

Plant manager Helmut Reiterer said "Sustainability requires decarbonisation, i.e. continuously reducing the CO₂ emissions from our production activities. We are placing an investment focus on energy-efficient production by modernising our machinery, but also on expanding green energy."

India: Adani Cement is upgrading its facility in Himachal Pradesh by installing a new 7800t/day double-stage cooler grate. This upgrade aims to increase efficiency, lower power consumption and clinker temperature and enhance waste heat recovery system performance, according to the company. The project involves replacing the first and second grates of the existing IKN pendulum cooler.

Germany: Holcim Deutschland has announced for the ‘most extensive’ modernisation of its Beckum cement plant to date. Local press has reported that the modernisation will commence with the installation of a Euro20m pendulum cooler to replace the plant’s existing tube cooler. The new cooler will reduce the plant’s CO₂ emissions and make separated CO₂ better suited for capture, according to the producer. The Beckum cement plant is the site of an on-going carbon capture trial.

General manager Jan Kristof Peters said “We want to implement all construction work as quickly as possible and with as little noise pollution as possible for the neighbourhood. As in previous years, we ask for our neighbourhood’s understanding.”

Romania: Holcim Romania has successfully upgraded pyroprocessing and cement grinding equipment at its Câmpulung cement plant in Argeș County. Germany-based KHD Humboldt Wedag supplied equipment for the upgrade. For the plant’s pyroprocessing line, this included a downcomer duct, water injection system and induced draught fan, as well as an upgrade to the clinker cooler. Meanwhile, the grinding line has received a new SKS Z 2500 dynamic separator, cyclones, process ducts and separator fan. The supplier says that the upgrade has increased the Câmpulung plant’s clinker capacity and the efficiency of its operations. The work took 14 months to complete from the signing of the contract in mid-2023.

Ghana: CIMPOR has appointed Germany-based ThyssenKrupp Polysius to build a 1280t/day flash activator for clay. The activator will supply calcined clay for use in the production of cement with a clinker factor as low as 50%. This can reduce the cement’s CO₂ emissions by 40% compared with ordinary Portland cement (OPC). The supplier’s contract covers engineering, supply of core equipment and supervision of the project. The equipment includes parts for clay handling, a hammer mill, a flash dryer and preheating and cooling equipment, as well as storage silos. The activator will be natural gas-fired.

Polysius Activated Clay product owner Leo Fit said "Our technology is not only more environmentally friendly, but also creates cost benefits for our customers like CIMPOR. In many regions, limestone is scarce and clinker has to be imported at high cost. At the same time, suitable clay sources are available. The increasing pressure to reduce greenhouse gas emissions is leading cement manufacturers to rethink. They need an alternative that is cost-efficient and at the same time provides high-quality cement. This is exactly what Polysius activated clay offers."

Jamaica: Caribbean Cement plans to launch an upgrade to expand its Rockfort cement plant’s capacity by 30% to 1.3Mt/yr in October 2023. The producer says that the expansion will cost US$40m and that the new capacity will come online in early 2025. The work will include enlargements of multiple kiln sections and the installation of a new coal dosing system, clinker cooler and clinker transport system.

Japan: Tokuyama Corporation has installed ABB’s Expert Optimizer automated optimisation system in the kiln line of its Nanyo cement plant. The system controls the line’s calciner, kiln and cooler processes. The supplier says that the technology will reduce the Nanyo cement plant’s thermal energy consumption by 3%.

Tokuyama Corporation "We selected ABB's Expert Optimizer to equalise operations and improve operational efficiency. As expected, we have significantly reduced the number of the operator manual operations normally spent on manual tasks.” It added “We believe that this solution will also support our young operators in learning the know-how of our operations efficiently."

India: Prism Cement has taken delivery of a pendulum cooler supplied by Germany-based IKN at its Prism cement plant in Maharashtra. The new equipment will replace the 6.1Mt/yr plant's existing air beam technology cooler. The supplier says that this will help to improve the efficiency of waste heat recovery (WHR) processes at the plant.

North Korea: State-owned Cheonnaeri Cement has completed a successful upgrade to its 1Mt/yr Cheonae cement plant in South Hamgyong Province. Korean News has reported that the upgrade involved the replacement of the plant's clinker cooler, burners and clinker and raw materials handling systems. A new bucket conveyor has more than doubled raw materials handling capacity.

Cheonnaeri Cement reportedly plans to further expand the capacity of the plant.
