China/US: A team led by Fengyin Du, then at Southeast University in Nanjing, developed a new cement formulation that reflects sunlight and emits heat more effectively than ordinary Portland cement, according to the New Scientist. The cement incorporates reflective ettringite crystals on its surface, which Du says “works like a mirror and a radiator, so it can reflect sunlight away and send heat out into the sky, so a building can stay cooler without any air conditioning or electricity.”

To make it, the researchers produce tiny pellets from limestone and gypsum, which are ground and mixed with water before being poured into a silicone mould covered in small holes. Ettringite crystals grow in slight depressions on the surface created by air bubbles, while an aluminium-rich gel allows infrared light to pass through, lowering heat retention.

Du said that tests at Purdue University, Indiana showed the cement’s surface was 5.4°C cooler than the air and 26°C cooler than conventional cement under the same conditions. The process is reportedly scalable and costs US$5/t less than ordinary Portland cement, as it can be produced at lower temperatures.

Norway: TotalEnergies, Equinor and Shell have announced that the first CO₂ volumes were transported by ship from Heidelberg Materials’ Brevik cement plant to Northern Lights’ Øygarden facilities. They were then injected 2600m under the seabed, 100km off the coast of western Norway. Phase one of the project has a storage capacity of 1.5Mt/yr. A second phase, approved in March 2025, will expand capacity to more than 5Mt/yr from 2028.

TotalEnergies’ senior vice president of carbon neutrality Arnaud Le Foll said “With the start of operations of Northern Lights, we are entering a new phase for the CCS industry in Europe. This industry now moves to reality, offering hard-to-abate sectors a credible and tangible way to reduce CO₂ emissions.”

Algeria: Biskria Ciment has exported 28,000t of white cement to the US from the port of Annaba aboard the M/V Anhui, according to the Annaba Port Company via L’Expression newspaper. The exports continue despite a 30% US customs duty on Algerian imports.

The company said it is maintaining shipments by leveraging the quality and price competitiveness of its cement.

India: Star Cement subsidiary Star Cement North East has been named preferred bidder for the Parewar (SN-IV) limestone block in Jaisalmer, Rajasthan. The 960-hectare block holds an estimated 271Mt of limestone. The company said the mining lease will strengthen its long-term raw material security once clearances and agreements are completed.

Star Cement operates 7.7Mt/yr of cement grinding capacity and 6.1Mt/yr of clinker capacity.

El Salvador: Data from the Central Reserve Bank (BCR) showed apparent cement consumption rose by 30% year-on-year in May 2025 to 4.8m 42.5kg bags, from 3.7m bags in May 2024, according to local press. The figure was the country’s highest monthly consumption in five years. Consumption from January to May 2025 reached 21.4m bags, up by 17% year-on-year from 18.4m bags in the same period of 2024.

From January to June 2025, imports of hydraulic cement totalled 0.3Mt, worth US$26m, up by 41% year-on-year from 0.21Mt in the same period of 2024. Guatemala was the leading supplier at US$12.7m, followed by Vietnam (US$6.6m), Japan (US$2.8m), Honduras (US$1.4m) and China (US$1.3m).

Canada: MV Tamarack arrived at the Port of Montreal on 22 August 2025, completing its maiden voyage and becoming the first newly built cement carrier to serve the Great Lakes in 20 years. The 12,500t vessel, owned by Eureka Shipping, a joint venture between CSL and SMT Shipping, was delivered on 23 July 2025 at Holland Shipyard in the Netherlands. The ship replaces two older vessels, offering the same capacity and reduced environmental impact, according to the company. MV Tamarack has a 10,700m³ cement hold, diesel-electric propulsion, shore-power compatibility, biofuel capability and energy-saving cargo systems.

Brazil: Cia. de Cimento Itambé has inaugurated a new kiln at its Balsa Nova plant in the Curitiba metropolitan region following a US$91.8m investment, according to the Curitiba government. Mayor Eduardo Pimentel and other members of the government were in attendance. The project reportedly increases clinker production capacity by 120% and adds 600,000t/yr of cement capacity, raising the plant’s total to 3Mt/yr.

The kiln will replace up to 50% of fossil fuels with renewable energy sources like biomass and industrial waste.

US: Shipments of Portland and blended cement, including imports, fell by 7.5% year-on-year to 8.91Mt in May 2025, according to the latest figures from the United States Geological Survey (USGS). Shipments for January to May 2025 totalled 37.9Mt, down by 6% from the same period in 2024. Texas, Missouri, California, Florida and Michigan accounted for 39% of production, while Texas, California, Florida, Ohio and Illinois received 40% of shipments.

Clinker production was 6.38Mt in May 2025 , compared with 6.46Mt in May 2024. For January to May 2025, clinker output dropped by 10% to 24.5Mt. Imports for the period declined by 5% year-on-year to 9.81Mt.

Colombia: Argos simultaneously loaded three cement ships for the first time at its Cartagena maritime terminal, moving over 31,000t of bulk cement. Platform 1 shipped 7000t to the Antilles and 3000t to the Caribbean, while Platform 2 loaded 21,000t for the US.

By the end of July 2025, Argos had shipped 570,000t of bulk cement on 44 vessels and 50,000t of bagged cement on 15 vessels.

Vice president of Argos Regional Colombia Carlos Horacio Yusty said “This milestone demonstrates the strength of our logistics network and the capacity of the terminal in Cartagena to respond to international markets. Having loaded three ships simultaneously sets a precedent in our operation and encourages us to continue growing in competitiveness.”

The Cartagena terminal has an installed capacity to handle 3.5Mt/yr of cement, clinker and raw materials.

Zimbabwe: China-based Shuntai Holdings is reportedly in a legal battle with Bryden Country School in Chegutu over the construction of a cement plant 497m from its boundary, according to local press.

The Board of Governors said that the company disclosed its plans in February 2025 to objections from the school and parents, with construction still continuing despite a High Court order halting construction. The Board said that there was no supporting documentation for the company to operate, as the area is zoned for education and also hosts a secondary school and university. Bryden said that it lodged multiple objections against Shuntai’s environmental and social impact assessment, which it claims failed to address key health and safety issues, yet the Environmental Management Agency (EMA) granted approval in April 2025. The school has since reportedly taken legal action against the regulator. A High Court judge ruled in July 2025 that Shuntai Holdings was in contempt of the stop-work order, but construction reportedly continues.

In July 2025, Shuntai administration manager Yan Bo confirmed the company has invested US$70m in the project, which is expected to produce 0.8Mt/yr of cement starting in 2026.
