Greece: Titan Group has entered a strategic partnership with thyssenkrupp Polysius to advance Polysius’ meca clay technology, which aims to reduce CO₂ emissions from cement production. The collaboration was formalised through a memorandum of understanding.

The meca clay system activates alternative cementitious materials to partially replace clinker, thereby lowering emissions and energy use without affecting performance, according to the company. Titan will first implement the technology at its Patras cement plant, with pilot activities scheduled for 2026 and further rollout planned. The partnership targets the production of low-carbon cement with a clinker-to-cement ratio below 40%, compared to 93% in ordinary Portland cement.

Germany: AUMUND Fördertechnik has launched its electrified Linear Calcination Conveyor (eLCC), which enables efficient clay calcination for limestone calcined clay cement (LC3).

LC3, composed of roughly 50% clinker, 30% calcined clay, 15% limestone and 5% gypsum, can reduce CO₂ emissions by up to 40% compared to ordinary Portland cement, according to the company. The technology enhances pozzolanic reactions between limestone and calcined clay, which provides additional alumina to form carboaluminate phases, improving strength and durability while lowering clinker use. Developed in collaboration with Holcim over four years, the eLCC was tested successfully at AUMUND’s pilot demonstration unit in Rheinberg, confirming its potential to support low-carbon cement production at industrial scale.

Jamaica: Caribbean Cement has resumed cement despatch operations at its Rockfort plant following Hurricane Melissa. The company completed safety inspections and restoration work to confirm the structural integrity of the site before restarting operations, according to Our Today news. The producer said it can meet market demand without supply chain disruptions due to its ‘strong’ inventory levels and fully stocked packing warehouses. The company currently holds over 33,000t of clinker, sufficient to produce 44,000t of cement.

Managing director Jorge Martinez said “Our ability to resume the despatch of cement so quickly after Hurricane Melissa is a testament to the strength of our safety protocols, the resilience of our operations, and the dedication of our people. By ensuring all silos and warehouses were secure and fully stocked, we are well positioned to meet Jamaica’s construction needs without interruption.”

Vietnam: Domestic cement sales reached about 18Mt in the third quarter of 2025, equal to 79% of second-quarter levels, according to the Construction Industry Development Centre (CIDC). The decline was attributed to prolonged storms and seasonal factors that disrupted operations and transport. Rising electricity, raw material and fuel costs also put pressure on production costs and profit margins.

By contrast, cement and clinker exports rose to nearly 9.5Mt, up on both the previous quarter and the first nine months of 2024. The increase was driven by efforts to expand into new markets in the Middle East, Africa and Eastern Europe, offsetting lower demand from the US, Taiwan and the Philippines. The Vietnam Cement Market Report noted that export profit margins remain under pressure due to high logistics costs and falling prices. The US’ 20% import tax on Vietnamese cement and Taiwan’s anti-dumping duties (in place until 2030) are also prompting companies to reassess pricing and market strategies.

According to the Vietnam Association of Building Materials, the final months of 2025 will bring ‘continued challenges’ from rising energy and input costs, but improving weather, faster public investment disbursement and signs of recovery in real estate are expected to boost demand for construction materials.

Germany: Rohrdorfer has inaugurated a new pilot plant for tempered clays at its Rohrdorf cement facility in a ceremony attended by regional and state officials. They included Parliamentary State Secretary to the Federal Ministry of the Interior Daniela Ludwig, who cut the ribbon alongside Rohrdorfer managing director Mike Edelmann.

The pilot plant has been operational since July 2025 and activates up to 50t/day of raw clay through thermal treatment. Tempered clays can replace clinker in cement, reportedly helping to cut emissions by around 30%, according to the company. The project is funded by the Federal Ministry for Economic Affairs and Climate Protection and the EU, and will receive up to €8.65m in funding.

Daniela Ludwig said “With this new plant, the Rohrdorf cement plant is once again proving that it is one of the most innovative companies in our region. Decarbonising the cement industry is a key task if Germany is to achieve its climate goals as planned.”

By the end of 2026, Rohrdorfer’s Net Zero Emission team will determine the optimal composition of raw clays and refine the thermal treatment process, paving the way for a large-scale facility capable of achieving up to 60% CO₂ reductions.

Mike Edelmann said “We’ve achieved a lot within our plants, but our influence ends at the factory gates. The lack of planning security regarding CO₂ transport and storage, uncompetitive electricity prices and an uncertain mining landscape are holding us back. We urgently need more support from policymakers if climate targets are to be met.”

Syria: The Ministry of Economy and Industry has signed a memorandum of understanding (MoU) with Iraq’s Vertex Investment Group to rehabilitate and expand the Hama Cement plant. The agreement covers the rehabilitation and operation of the plant’s third line, increasing capacity from 3300t/day to 5000t/day of clinker within 13 months. It also includes the construction of a new 6000t/day line, which will raise the plant’s total production capacity to around 11,000t/day over the next five years. The MoU also provides for worker training, application of international quality standards, and compliance with environmental and occupational safety requirements.

Malawi: Huaxin Cement successfully ignited its new 2000t/day clinker production line on 28 September 2025, marking the official start of trial production, according to a post on Linkedin by the producer. Once fully commissioned, the plant will add 0.8Mt/yr to the company’s cement capacity. The project reportedly incorporates energy-efficient equipment, low-carbon calcination technology and a full-process DCS automated control system, creating a closed loop from raw material crushing to packaging. The facility will generate 500 direct jobs, with 90% allocated to local workers.

Construction began on 28 October 2024 and was completed in just 11 months. The company said close coordination between the plant and EPC teams helped overcome multiple challenges to deliver the project.

Rwanda: Cement producer Cimerwa will invest about US$190m in a new clinker plant, aiming to reduce its dependence on imports and save an estimated US$2.88bn in foreign exchange over the next 25 years. CEO Mangesh Kumar Verma said the plant, which will be built in Musanze, is expected to begin operations within two years with a capacity of 0.72Mt/yr of clinker. The plant will meet the company’s local demand of 0.54Mt/yr, with the surplus exported. Verma said that if limestone reserves prove larger than expected, there is provision to add another line. The investment follows rising costs from importing clinker, which currently amount to around 0.36Mt/yr at a cost of US$3.7m–4.0m. Verma added that clinker makes up about 70% of cement production costs, rising to 95% when imported.

Cimerwa’s unaudited financial results for the nine months ending 30 June 2025 showed that revenues were up by 50% year-on-year to US$75m, driven largely by its July 2024 acquisition of Prime Cement. However, profit before tax dropped by 23% to US$7.7m, reportedly due to input cost increases and continued depreciation of the Rwandan Franc. The company said that the Musanze clinker plant will stabilise production costs and position Rwanda as a net exporter, supporting large-scale infrastructure projects such as the New International Airport in Bugesera.

India: Dalmia Bharat, through its subsidiaries, has announced a strategic investment of approximately US$397m in Maharashtra and Karnataka. The company will set up a 3.6Mt/yr clinker unit and a 3Mt/yr grinding unit at its existing Belgaum plant in Karnataka, alongside a new greenfield split grinding unit of 3Mt/yr in Pune, Maharashtra. The projects, funded through a mix of debt and internal accruals, are expected to be commissioned by the fourth quarter of the 2027 financial year. Following completion, and factoring in ongoing 2.9Mt/yr expansions in Assam and Bihar, Dalmia Bharat’s installed capacity will rise to 55.5Mt/yr.

The Belgaum expansion will strengthen supply in southern Maharashtra and deepen the company’s reach in Karnataka, while the Pune plant will focus on the untapped western Maharashtra markets.

Puneet Dalmia, managing director and CEO of Dalmia Bharat, said “This investment is a significant step in our Phase II expansion strategy, bringing us closer to strengthening our position as a pan-India player and to reach our intermittent goal of 75Mt/yr capacity by the 2028 financial year. The increase in our production capacity is primarily to meet the growing infrastructure demand in Western India.”
