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.

Bangladesh: Chhatak Cement Factory has ceased production due to severe gas and limestone shortages, despite a modernisation project having reached 91% completion.

The Bangladesh Chemical Industries Corporation (BCIC) began a US$54.7m project to convert the plant’s production process from wet to dry in 2016, in order to increase capacity to 1500t/day (0.45Mt/yr). The project cost rose to US$116m, with US$68m spent by November 2024. However, the plant remains idle despite the completion of construction works over a year ago, due to the lack of a new gas pipeline and ropeway to import limestone from India. This ropeway was supposed to transport limestone from the Komorrah Limestone Mining Company in Meghalaya.

The project's committee has proposed extending the deadline to June 2026 and allocating an additional US$25m for a 43km gas pipeline from Sylhet to Chhatak. Trial runs are now being conducted every 15 days in order to prevent the plant’s machinery from rusting.

Project director Abdur Rahman Badsha said that the Chinese contractor responsible for the ropeway construction, Nanjing C-Hope Cement Engineering Group, is awaiting a subcontracting agreement with KLMC to begin work in India.

India: JK Cement has won a bid for 250Mt of limestone reserves in Lakhpat Punrajpur, Kutch, Gujarat, through a Request for Proposal from Gujarat Mineral Development Corporation. The reserves are expected to supply the company with raw materials for the next 40 years.

JK Cement Group president Amit Kothari said "This strategic partnership not only strengthens our resource base, but also highlights our focus on ensuring a steady supply of premium raw materials for high-quality cement production.”
