Global Cement News

Kazakhstan: Steppe Cement sold 749,000t of cement during the first half of 2023, down by 11% year-on-year from 837,000t in the first half of 2022. The value of sales fell by 13% to US$38.5m from US$44.4m.

Australia: Korea Hydro & Nuclear Power has concluded a memorandum of understanding (MoU) with Hallett Group and renewable energy consultancy Elecseed. Business Korea Daily News has reported that the signatories will collaborate on Hallett Group’s Green Cement Transformation project. The project aims to reduce CO₂ emissions by 300,000t/yr, and eventually by 1Mt/yr, by producing reduced-CO₂ cement from three industrial waste streams. It will also use green hydrogen. The US$83.6m project has US$13m-worth of funding from the government.

Additionally, the partners say that they will seek to foster a ‘globally competitive hydrogen export industry.’

Ghana: The Bureau of National Investigations (BNI) and the Ghana Revenue Authority (GRA) have arrested managers of Wan Heng Ghana. The Business and Financial Times newspaper has reported that the cement producer is suspected of neglecting to pay US$43.1m in tax. An investigation showed that the company received sufficient imported clinker to produce US$120m-worth of cement between 2018 and 2021, yet declared only US$19.6m-worth of sales. Management then reportedly refused to cooperate with further investigations, leading to the arrests. Wan Heng Ghana produces Sol brand cement.

The Chamber of Cement Manufacturers Ghana (COCMAG) affirmed its commitment to ensuring fair competition and ethical practices within the cement industry. It represents cement producers in the country, including Wan Heng Ghana.

Vietnam: Tan Quang Cement says that it fell short of its first-half 2023 cement production target by 80,000t at it 800,000t/yr Trang Da cement plant in Tuyen Quang. The plant will ‘presently’ enter a shutdown period for maintenance. Việt Nam News has reported that the producer attributed the shortfall in production to low demand, amid general national overcapacity.

Portugal: Cimpor Portugal has signed a contract with Germany-based KHD Humboldt Wedag (KHD) for an upgrade to production line 7 at its Alhandra cement plant. The project is intended to increase the production capacity at the plant to 3600t/day from 3000t/day and increase the line’s alternative fuels thermal substitution rate to over 80%. It will also be the first installation of KHD’s Pyrorotor alternative fuel combustion reactor in the country.

The scope of the engineering and supply contract comprises:

• New HKSK 224/335 preheater ID fan
• New downcomer duct
• New preheater with 8064/5-type HEM cyclones
• Pyroclon R calciner with Pyrotop mixing chamber. The Pyroclon R will utilize fine refuse-derived fuel (RDF) and natural gas
• 4m x 10m Pyrorotor alternative fuel combustion reactor
• Pyrobox coal firing system for process start-up and operation balancing
• Shortening of the existing kiln and installation of new kiln inlet chamber with bypass extraction
• New kiln drive station 2 (the existing girth gear and two pinions will be reused)
• New kiln hood and take-off of tertiary air from the cooler roof
• New main kiln burner designed to use more than 50% alternative fuels (but will also be capable of burning natural gas, as well as liquid fossil and alternative fuels)
• New Pyrofloor PFC²829AW cooler with a Pyrocrusher PRC 420-3ES clinker crusher.

KHD will also be supplying its KHD ProMax software product as part of the project.

Matthias Mersmann, chief technology officer at KHD, said “The decision by Cimpor Portugal to opt for KHD pyroprocessing equipment - and especially the Pyrorotor - underlines the leading market position of KHD, as well as the outstanding capability of KHD’s unique alternative fuel-processing solution.”

Project execution will be led by KHD Germany, with support from Humboldt Wedag India and the Turkish branch office of Humboldt Wedag. Commissioning of the upgraded production line is scheduled for 2025.
