US: Environmental groups have welcomed the imminent start of work to rehabilitate Heidelberg Materials’ former Permanente cement plant and quarry in California, which ceased operations in 2023. The project, to start on 29 July 2025, will clean up a polluted section of the Permanente Creek, which flows from the Santa Cruz Mountains past the quarry site an into the San Francisco Bay.

The work was required as part of the settlement to a lawsuit filed in 2011 by the Sierra Club against Lehigh Southwest Cement company, which was subsequently acquired by Heidelberg Materials. Under the settlement, the company is required to restore 2.7km of the creek by 2030. The restoration will remove sediment that contains selenium, nickel and other heavy metals that have washed out of the quarry over the years. Workers also will plant native vegetation, build pools for trout, and stabilise slopes. The project's cost is estimated at US$25m, according to Heidelberg Materials’ David Perkins.

Environmental groups have said the work is overdue. "We're relieved that it's finally actually happening," said Katja Irvin, Guadalupe Group chair of the Sierra Club's Loma Prieta Chapter, based in Palo Alto. "There is mining waste in the creek, and concrete barriers in the creek. The slopes have been eroded. All of those problems eventually will be fixed.”

Azerbaijan: Azerbaijan exported 449,800t of cement and clinker in the first half of 2025 according to the State Customs Committee. This marks a 33.8% rise compared to the same period of 2024. The growth reflects rising demand for Azerbaijani cement in neighbouring and regional markets, particularly as reconstruction and infrastructure projects accelerate in countries such as Georgia and Türkiye, as well as parts of Central Asia.

The committee said that cement products accounted for 0.22% of the country’s total exports and 1.65% of non-oil exports during the reporting period. It added that this increase supports Azerbaijan’s broader strategy to boost non-oil exports and diversify its economy.

Bosnia & Herzegovina: Heidelberg Materials BiH’s net profit increased by 10.2% year-on-year to €14.7m during the first six months of 2025. Its revenue increased by 7% to €55.1m. Germany-based Heidelberg Materials has been present in the Bosnian market since 2000, when it acquired a majority stake in the former Tvornica Cementa Kakanj cement plant.

Mexico: Yakup Bayram, the CEO of PaneraTech, has been announced as the first keynote speaker at the 19th Unified International Technical Conference on Refractories (UNITECR) due to take place on 27 - 30 October 2025 in Cancun, Mexico. Bayram will discuss the use of artificial intelligence in refractories. He is also scheduled to moderate a panel entitled ‘Sustainability With Intelligence in the Refractories Industry.’ The call for papers for the event has closed and around 180 presentations are currently planned.

UNITECR held its first event in 1987 in Tokyo, Japan. The most recent outing took place in in Frankfurt, Germany, in 2023. The event, hosted by the German Refractory Association, featured over 200 speakers and more than 1100 participants in total. The meeting in 2025 is being hosted by the Latin American Association of Refractories Manufacturers (ALAFAR).

Algeria: The Minister of Industry Sifi Ghrieb has announced a project to build two new low-carbon cement plants in Djelfa and Relizane in central Algeria with a capacity of 1.5Mt/yr and 2Mt/yr respectively, according to Zawya news. An existing cement plant in Djelfa will also see its capacity expanded by 1.5Mt/yr.

The new projects will boost Algeria’s cement capacity to 42Mt/yr. It currently has a cement demand of 30Mt/yr and exports a surplus of 12Mt/yr of cement. Ghrief reportedly discussed plans to expand the Djelfa plant in March 2025 with a delegation from the China State Construction Engineering Corporation. A separate 2Mt/yr low-carbon cement plant, a partnership between local, UAE-based and India-based companies, is also under construction in El Milia, utilising slag and fly ash from a nearby power station and steel complex.
