Australia: Boral will receive US$15.4m in government funding for a kiln feed optimisation project at its Berrima Cement Works, with CO₂ emissions expected to reduce by up to 100,000t/yr, based on predicted production rates. The Powering the Regions grant will support the producer’s installation of a new specialised grinding circuit and supporting infrastructure, which will raise the use of alternative raw materials in kiln feed to 23% from 9%, lowering the amount of limestone used.

Boral will use steel manufacturing by-products and industrial waste, including granulated blast furnace slag, steel slag, cement fibre board, fly ash and recycled fine concrete aggregates. The project will be operational in 2028.

The head of innovation and sustainability at Boral, Ali Nezhad, said “In terms of the resulting emissions intensity of the manufactured clinker, the project will result in up to 11% reduction in clinker emission intensity, 9% attributable to a reduction in calcination emissions and 2% attributable to thermal efficiency gains.”

India: UltraTech Cement has commissioned a 3.35Mt/yr brownfield clinker line and one of two 2.7Mt/yr cement mills at its Maihar unit in Madhya Pradesh. The second grinding mill will be commissioned in the first quarter of the 2026 financial year. The producer also commissioned brownfield expansions at its Dhule grinding unit in Maharashtra (1.2Mt/yr) and Durgapur grinding unit in West Bengal (0.6Mt/yr), and launched its first bulk terminal in Lucknow, Uttar Pradesh, with a handling capacity of 1.8Mt/yr.

“Consequent to the above, the company’s total domestic grey cement manufacturing capacity stands at 183.36Mt/yr. Along with its overseas capacity of 5.4Mt/yr, the company’s global capacity stands at 188.76Mt/yr,” UltraTech Cement said.

Azerbaijan: Cement production rose by 6% year-on-year to 0.58Mt the first two months of 2025, up from 0.55Mt in the previous corresponding period. Cement clinker output increased by 11% to 0.61Mt from 0.55Mt in the same period of 2024, according to the State Statistical Committee.

The State Customs Committee reported exports of 0.14Mt of cement and clinker at a value of US$9.1m. This represents an increase of 32,000t (29%) by volume and US$2.7m (43%) by value compared to the same period in the previous year.

Australia: The Australian government’s ‘unwillingness’ to impose a carbon levy on imported cement, lime and clinker is threatening decarbonisation efforts and could cost up to 1400 jobs, according to the Financial Review.

The Cement Industry Federation, which represents local producers Adbri, Boral and Cement Australia, has said that the absence of a carbon levy on imports from countries with less robust climate commitments paved the way for the offshoring of local manufacturing, a process known as ‘carbon leakage’.

It said “Not addressing the issue of carbon leakage in a timely manner will be detrimental to Australian cement and lime manufacturing and could lead to the unnecessary loss of key Australian cement and lime facilities."

Imports currently account for over 40% of domestic clinker consumption and originate largely from southeast Asia. In 2023, an energy expert was appointed by the government to assess the feasibility of an Australian carbon border adjustment mechanism, with a final recommendation expected to be delivered in 2024. However, only an interim report was released in November 2024, with the final advice now reportedly due after the election in May 2025.

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.

France: Heidelberg Materials has ordered an MVR 5000 C-4 vertical roller mill from Gebr. Pfeiffer for its Airvault plant to grind ultra-fine Portland cement. The mill will be equipped with an SLS 4500 VC classifier to produce 145t/hr of Portland cement at a fineness of 4500cm²/g. The design allows for high-efficiency grinding and lower CO₂ emissions by reducing clinker content in blended cements. The contract is managed by China-based contractor CBMI. Commissioning is expected in the first half of 2026.

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.

India: Ambuja Cements will invest US$286m in two cement carriers and eight clinker carriers. The company expects to finalise a shipbuilding contract within 15 days, with Cochin Shipyard and Swan Defence and Heavy Industries under consideration.

Each 38,500t Handymax cement carrier will cost US$45.8m, while each 9200t clinker carrier will cost US$22.9m. The clinker carriers will have a 30m beam, 4m draft and 150m length, increasing cargo capacity from the traditional 3000t to 9200t per trip.

Peru: National cement despatches reached 0.99Mt in January 2025, down by 2% compared to January 2024 and by 0.7% in the 12-month cumulative period, according to ASOCEM. Cement production declined by 6% year-on-year to 0.87Mt, while clinker production dropped by 30% to 0.59Mt. Over the 12-month cumulative period, cement production fell by 3% and clinker production declined by 9%.

Cement exports reached 10,200t, down by 2% year-on-year and by 5% in the 12-month cumulative period. Clinker exports increased significantly, by 122% to 73,600t in January 2025, but were down by 18% in the cumulative period.

Cement imports rose by 63% year-on-year to 50,000t in January and by 23% in the 12-month period. Clinker imports fell by 29% to 44,000t in January but increased by 28% in the cumulative period.
