US: Hoffmann Green Cement Technologies has obtained ASTM C1157 certification for its H-UKR 0% clinker cement after several months of testing and trials at the University of Miami.

The benchmark standard evaluates cements on their performance, regardless of their composition. H-UKR cement is now officially recognised as a hydraulic cement that can be used in all general construction applications, whether structural or non-structural. Hoffmann Green said that this is the first time that a 0% clinker cement has obtained this certification.

Co-founders Julien Blanchard and David Hoffmann said “This international technical recognition marks a decisive step forward in our certification process, which is part of a broader ambition to expand the applications of our 0% clinker cement through continuous innovation. It validates the reliability and sustainability of our technology on a global scale, in accordance with the most demanding standards. With this certification, H-UKR has confirmed itself as a game changer technology capable of profoundly transforming an industry that has remained unchanged for more than two centuries.”

Iraq: Delta Cement Company and Suzhou Sinoma have celebrated the completion of a 6000t/day clinker production line. The two partners completed construction, commissioning and production over a period of 16 months. The plant’s cement grinding equipment was commissioned on 24 December 2024, and the clinker line was commissioned on 30 June 2025.

Kyrgyzstan: President Sadyr Japarov has launched a new 0.8Mt/yr clinker production line at the Kant Cement plant. The project created over 300 new jobs and is expected to increase cement supply to the domestic construction industry. Construction of the dry-process line began in early 2024, with equipment supplied by China's Beijing Triumph International Engineering, a subsidiary of Sinoma. US$50m of the US$61m total investment was provided by the Eurasian Development Bank. In 2024, the plant produced 1.15Mt of cement.

President Japarov said “The launch of the new line is not just another production facility. It is a symbol of our industrial growth, professionalism of domestic engineers and workers, and, most importantly, the trust of investors in our country.”

Cameroon: Cimencam, a subsidiary of LafargeHolcim-Maroc Afrique, inaugurated its subsidiary Cimencam Figuil’s (CIMFIG) new clinker and cement production line at the Figuil cement plant in Cameroon’s North Region on 12 June 2025, according to the Business in Cameroon newspaper.

The new line, part of an expansion project at the 40-year-old Figuil cement plant, has a cement capacity of 500,000t/yr and a clinker capacity of 1,000t/day. Cimencam invested US$88m in the expansion. The upgraded plant will supply cement to the North, Adamaoua and Far North regions, and aims to enter the Chadian market, which reportedly experiences frequent shortages and high prices.

Vietnam: Vietnam exported 2.98Mt of cement and clinker worth US$113m in May 2025, up by 17% in volume and 12% in value year-on-year, according to the government’s National Statistics Office. Between January and May 2025, exports totalled 14.18Mt worth US$523m, marking a 6% rise in volume and 2% in value year-on-year. In 2024, the country exported 29.67Mt of cement and clinker for US$1.14bn, down by 5% in volume and 14% in value from 2023.

Guinea: Cement has become scarce across Guinea, halting many private construction sites and driving prices higher. According to a report by the Guinee7 newspaper, the country has six producers that operate seven cement plants, with a combined production capacity of around 3.6Mt/yr. This is up from 2.2Mt/yr four years ago – an increase of nearly 60%.

However, two plants have shut down due to a lack of clinker. Industry sources propose reviving domestic clinker production but caution that stabilisation could take several months.

Russia: Katavsky Cement has modernised rotary kiln No. 4, raising clinker production capacity by 15% from 888,000t/yr to 927,000t/yr. According to Cemros, the project formed part of a corporate programme of improvements to increase production efficiency, valued at around US$760,000. Specialists reportedly encountered the problem of clinker defects when increasing the feed of raw meal due to insufficient heat exchange in the kiln system. To eliminate the problem, the plant updated the cyclone heat exchanger, stabilised the air supply and combustion of additional fuel, and improved the clinker cooling system.

General director Vyacheslav Lyubimtsev said “Modernisation of kiln No. 4 is a consistent step in the development of the plant. In 2024, similar work was carried out to increase the productivity of furnace No. 3 by 30%. The new result confirms the effectiveness of the chosen strategy.”
