China: Authorities in the province of Hunan have identified a cement plant as the source of thallium contamination in the Leishui River following a botched demolition at the end of 2024, according to Sixth Tone news.

Yongxing County officials said that rainfall had washed thallium-laden dust from a dismantled kiln into the river. Levels peaked at 0.13μg/L, exceeding the national standard of 0.1μg/L, but have since returned to safe levels. The nearby city of Chenzhou is reportedly a hub for non-ferrous metal mining and processing, and a number of Chinese cement plants have begun to process industrial solid waste in recent years. According to Peng Yingdeng, a researcher at the Ministry of Ecology and Environment, this method is a common approach for hazardous waste disposal, but can lead to high concentrations of thallium salts in the kiln’s residue. The owner of the plant, Hunan Liantian Cement, added solid waste management to its list of businesses in September 2024.

The local government has despatched teams to apply chemical treatments to the affected areas, with water quality since returning to safe levels. Local residents’ drinking water was reportedly not affected.

Indonesia: Indocement recorded sales of 20.5Mt of cement and clinker in 2024, up by 1150t (6%) year-on-year. Corporate secretary Dani Handajani said the producer held a 30% domestic market share, with a 38% share in Java and a 21% share outside Java, according to the Cement Association of Indonesia (ASI). Handajani said that domestic bulk cement sales increased due to the new capital city project and acceleration of infrastructure projects in Java. Its exports reached 0.32Mt.

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.”

China: NovaAlgoma Cement Carriers has confirmed an order for a 38,000t methanol dual-fuel pneumatic cement carrier by Zhejiang Xinle Shipbuilding, for delivery in 2027.

The vessel will be chartered under a long-term contract by Holcim. Other features include an air lubricating system and a waste heat recovery system, which will recycle exhaust gases to generate electricity.

“By increasing the quantity intake and burning green methanol, the CO₂ emissions on these shipments will be reduced by more than 60% per year in comparison to current freight flows, ie 0.18Mt of CO₂ reduction over a period of 10 years,” NovaAlgoma said.

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.
