Bangladesh: Chhatak Cement’s plant in Sunamganj remains idle despite construction completing in March 2023, with production suspended due to unresolved gas and limestone supply issues, according to the Prothom Alo newspaper. The plant project began in 2016. New details confirm that the Bangladesh government has approved subcontracting of a cross-border ropeway to import limestone from India. Local firm Komorah Limestone Mining Company (KLMC), which already supplies limestone to Chhatak Cement, is in talks regarding the role. China-based contractor for the project, Nanjing Sea-Hope Cement Engineering, has agreed ‘in principle’ to this handover as of 18 March 2025, according to Chhatak Cement managing director Abdur Rahman.

Project officials stated that, once the new plant begins operations, it will be capable of producing 1500t/day of clinker and 500t/day of cement, triple its previous capacity. Reporters conducted a site visit on 8 April 2025, observing that a jetty had been constructed on the riverbank to unload clinker from the plant for grinding elsewhere. A conveyor system has been set up to move cement bags directly from the plant to transport, and a new conveyor belt has also been installed alongside the existing belt.

India: Shree Cement has secured mining rights for a limestone quarry spanning 912 hectares. The reserve has a capacity of 211Mt and is situated in Jaisalmer District, Rajasthan.

Iraq: Kurdistan Region prime minister Masrour Barzani will inaugurate the Dabin cement plant and power station in Erbil Governorate today, 12 May 2025, according to Kurdistan24 news. The foundation stone was laid nearly two years ago, on 22 June 2023.

The project spans 212,000m² and was built by China Power Investment Corporation. It includes a 6300t/day capacity cement plant and a 52MW power station, intended to both support the energy needs of the plant and feed into the broader grid to alleviate strain on regional electricity supplies. A limestone quarry 1km away from the plant supplies the limestone for production, where geological surveys have reportedly confirmed reserves of 150Mt, sufficient to sustain operations for at least 50 years.

Raw material is transported to the plant using a 1400t/hr capacity industrial crusher. The processed material is stored in four 10,000t silos, each 18m in diameter and 56m tall.  

Sweden: A court has granted Heidelberg Materials a 30-year licence to continue limestone mining at its Slite quarry on the island of Gotland, securing the future of the plant that produces 75% of Sweden’s cement. The court ruling replaces a 2022 four-year concession and follows a 2021 rejection of a long-term extension that had threatened cement rationing and job losses, according to Reuters.

Heidelberg Materials deputy CEO Karin Comstedt Webb said “The permit ensures a robust supply of cement to Sweden's construction sector for many years.”

Cambodia: The Cambodian government has approved the construction of a new cement plant on a 99-hectare site inside Prey Lang Wildlife Sanctuary, awarded in January 2025 to KP Cement. This decision comes despite a 2023 moratorium on new mining licences in Prey Lang to protect the forest and local ecosystem. Local newspaper Mongabay previously conducted an investigation into KP Cement, allegedly uncovering rampant deforestation at the company’s mine where limestone and marble are being excavated. It reports that documents published in the March 2025 edition of Cambodia’s Royal Gazette, which lists new laws and government announcements, show that a 50-year lease on a 99-hectare plot of land inside Prey Lang Wildlife Sanctuary was awarded to KP Cement on 13 January 2025.

The plant will source limestone from a nearby mine less than 1km away. Coal for the operation will be imported via Sihanoukville port and transported over 440km to the site. Local communities have expressed alarm over environmental degradation, health risks from limestone dust and being excluded from decision-making.

Gabon: The Gabonese government and Ciments d'Afrique (Cimaf Gabon) have signed an investment agreement for the construction of a third cement production line. The US$41.1m project will increase Cimaf Gabon's cement production capacity by 1Mt/yr to 1.85Mt/yr.

Cimaf Gabon also holds a permit to exploit a major limestone deposit around Ntoum and will build a clinker production unit in the area, requiring more than US$148m in investment.

Cimaf Gabon’s general director Janah Idrissi El Mehdi said “This plant, located a stone's throw from Ntoum in the Estuaire province, will bring significant benefits to the entire region, particularly in terms of job creation (1400 in the project phase and 500 in the operational phase). It will contribute to improving the living conditions of the surrounding populations.”

Bangladesh: The Bangladesh Cement Manufacturers Association (BCMA) has requested that the National Board of Revenue (NBR) lower an import tax on clinker to US$1.7/t. The lobbying is taking place ahead of the upcoming budget for the 2025 – 2026 financial year, according to the Financial Express newspaper. The association also expressed concern that a 10% duty was levied on limestone imports, but it expects this to be relaxed in the upcoming budget. The BCMA has urged the NBR to simplify customs regulations and impose a tariff system on value-added tax (VAT) calculations.

India: The Tamil Nadu government will impose a mineral-bearing land tax of US$1.82/t on limestone under the Tamil Nadu Mineral Bearing Land Tax Act 2024. This tax, payable in advance on mineral dispatch, is in addition to existing royalty charges. The announcement follows Karnataka’s recent decision to levy US$0.29/t on limestone mined.

The tax will raise production costs for cement producers in the region, particularly affecting Ramco Cements, which has 52% of its clinker capacity in Tamil Nadu, and Dalmia Bharat, which has 23%. Other Indian cement producers are less affected, with UltraTech Cement only holding 4% capacity in the area, and ACC 2%. This could mean that the cost increase is passed on to consumers, raising the price of cement.

Nigeria: Bauchi State Government, in partnership with Resident Cement, has commenced work on a US$1.5bn cement plant in Diji Village, Gwana District, Alkaleri Local Government Area, according to Arise News.

Resident Cement Group Chairman Abbas Junaid stated that limestone deposits in the area are sufficient to sustain a 10Mt/yr capacity plant for 100 years. The company has begun drilling and will deploy four rigs to complete the project within two months, with full construction of the plant to begin in three months.

US: Construction service company Bridgesource led a community meeting to propose a cement plant in Glendale, Nevada. More than 150 people attended the meeting to discuss the project.

The proposed cement plant would occupy about 101 hectares and include a 122m preheater tower and a 137m smoke stack. Additionally, a 81 hectare plot of land is being considered for a limestone mining operation to supply the plant. The deposit is expected to sustain the plant for 70-80 years.

Bridgesource said that the site poses multiple advantages for the location of a cement plant, citing its proximity to transportation infrastructure, as well as access to natural gas from the Kern River pipeline and sufficient power supply from the national grid. The company stated that the proposal would create over 200 jobs.
