Cool Planet Technologies concludes testing of membrane module carbon capture technology 10 December 2025
UK: Cool Planet Technologies has successfully tested its third-generation carbon capture membrane module at its Grimsby site. The test validated the scalability and performance of the company’s membrane process at flow rates of up to 37,000t/yr of captured CO₂ and recovery rates of 95% CO₂. Further tests were also conducted with a lime manufacturer in for a project which will use Cool Planet’s technology to decarbonise one of its kilns. The module will now be deployed at Holcim’s Höver cement plant in Germany for a 12-month demonstration project.
Andrew Corner, CEO of Cool Planet, said “This achievement validates years of innovation and positions Cool Planet at the forefront of lower cost, scalable industrial carbon capture solutions. The UK tests not only confirmed the performance and robustness of our technology, but also significantly strengthened industry confidence in our ability to help them deliver on their global decarbonisation goals.”
Bulgaria: Greek carbon storage company EnEarth has signed a term sheet with Heidelberg Materials to negotiate exclusive agreements for the transport and storage of CO₂ from the Devnya cement plant. The project aims to capture, transport and store 0.8Mt/yr of CO₂ from the plant. It is part of a wider CCUS initiative by parent company Heidelberg Materials, called ANRAV, which aims to be the first full-chain CCUS project in Eastern Europe. It has received a €190m EU grant, including €38m for the storage site, and is scheduled to be operational before 2030.
US cement shipments up by 7% in July 2025 10 December 2025
US: Total shipments of Portland and blended cement, including imports, reached an estimated 9.99Mt in July 2025, up by 7% from July 2024. Year-to-date shipments totalled 57.0Mt, down by 3% from the same period in 2024. Texas, Missouri, California, Florida and Alabama were the top cement-producing states. Texas, California, Florida, Ohio and North Carolina together accounted for 38% of total shipments.
Clinker production in July 2025 totalled 6.64Mt, nearly unchanged from July 2024. Cumulative clinker output for January to July 2025 fell by 7% year-on-year to 37.5Mt. Missouri, California, Texas, Florida and Alabama produced the most clinker.
Iranian cement output down by 10% in March to September 2025 10 December 2025
Iran: Cement output fell by 10% year-on-year to 31.7Mt in the first half of 1403 (21 March – 22 September 2025), down from 35.1Mt, according to Ali Akbar Alvandian, secretary of the Cement Industry Association. He attributed the decline to weaker domestic demand and energy constraints.
Clinker output also dropped by 10% in the first quarter (21 March – 21 June 2025), recovered in July and August 2025, then declined by 4.5% in September 2025. Cement production in the sixth month (22 August - 21 September) fell to 5.7Mt from 6.4Mt a year earlier.
Exports rose by 7% to 6.9Mt of cement and clinker, while domestic demand fell by about 10%. A nationwide power cut in May 2025 reportedly halted production and temporarily increased prices.
