India: UltraTech Cement has increased its production capacity by 1.4Mt/yr through debottlenecking and ‘efficiency improvements’ at multiple sites across India.

It added 0.6Mt/yr of grinding capacity at Nagpur in Maharashtra and 0.8Mt/yr across Panipat and Jhajjar in Haryana. The company’s total domestic grey cement capacity now stands at 184.8Mt/yr, while its global capacity has reached 190.2Mt/yr.

India: Nuvoco Vistas will build a 2Mt/yr grinding unit in Kutch as part of its plan to refurbish and put into operation the recently acquired assets of Vadraj Cement. The project adds US$35m to the US$141m originally allocated to restart Vadraj’s cement assets in Kutch and Surat, bringing the total planned investment to US$177m, phased over 2025 to 2027. Nuvoco aims to commission the grinding unit and start up the existing Vadraj assets by December 2027. These include a 3.5Mt/yr clinker unit in Kutch, a 6Mt/yr grinding unit in Surat and limestone reserves.

Nuvoco’s total production capacity will increase to around 31Mt/yr. The company currently sells 1Mt/yr of cement in Gujarat from its facilities in Rajasthan, but post-commissioning, the Kutch and Surat sites will serve Gujarat and northern Maharashtra and release Rajasthan capacity for northern markets.

India: Shree Cement has commissioned its new grinding unit in Etah, Uttar Pradesh, with an investment of US$917m, funded through internal accruals. The plant’s location near railway lines allows for efficient transport of raw materials from Rajasthan, and the unit will distribute cement via roadways and a new highway-access road. It features ‘zero-waste’ operations, air-cooled screw compressors to reduce water usage and advanced filtration systems.

The plant will consume 5000t/day of fly ash from the adjacent Jawaharpur Thermal Power Plant. A solar power installation is planned within two to three years.

India: Dalmia Cement (Bharat), a material subsidiary of Dalmia Bharat, has commenced commercial production at its cement grinding unit at Rohtas Cement Works in Rohtas district, Bihar, increasing capacity by 0.5Mt/yr to 1.6Mt/yr.

With this rise in cement capacity, the group’s total cement production capacity now stands at 49.5Mt/yr.

India: The Ramco Cements has increased the capacity of its Kalavatala plant in Andhra Pradesh from 2Mt/yr to 2.4Mt/yr by de-bottlenecking and optimising the cement mill. The producer's total cement grinding capacity now stands at 24.4Mt/yr.

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.

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.”

India: UltraTech Cement has increased its production capacity by 1.2Mt/yr through debottlenecking efforts. The producer said that it had identified multiple efficiency enhancement opportunities across various locations as part of its capacity expansion programmes. The additional capacity includes 0.8Mt/yr at the integrated Hirmi plant in Chhattisgarh and 0.4Mt/yr at the Roorkee grinding unit in Uttarakhand. Ultratech’s domestic cement capacity now reportedly stands at 179Mt/yr.

India: Dalmia Bharat has commenced commercial production at its expanded cement grinding facility in Lanka, Hojai district, Assam. The expansion by subsidiary Dalmia Cement (North East) has added 2.4Mt/yr to the company’s total production capacity, which has now reached 49Mt/yr. Capacity utilisation stands at 60% on a pro-rata basis. The expansion cost US$80.4m, funded through equity, debt and internal accruals. The additional output is expected to meet rising cement demand in the northeastern region.
