Kenya: East African Portland Cement (EAPCC) has closed its Athi River plant for a US$3m upgrade to boost production capacity.

Oliver Kirubai, EAPCC's managing director, said "We are doing the second phase of our machines upgrade, which is basically targeting to increase our output. Our target is that by June 2026 we should be able to produce 1Mt/yr of cement." He added "Seven local contractors are spearheading the upgrade of this plant. They will work with us during the 25-day closure of this facility." The current production capacity of the plant is 310,000t/yr.

EAPCC recorded a loss of US$9.8m for the financial year ending June 2023, despite making a profit of US$4m in the previous year. This shift was due to increased costs elevating the firm's cost of sales to US$29.4m from US$29.9m, despite a 37% increase in revenues to US$21.9m from US$15.9 in the previous year.

Italy: Scientists Gregory Chass and Kun Tian have developed a sustainable concrete from wet waste materials through their company Mesoscale Engineering Halcyon. This 'green concrete' concept was conceived in Garbatella and will first be tested on the district's pavements. The concrete, made by combining and recycling industrial CO₂ emissions with brine from saltworks, is part of the Clean Energy Transition Partnership. It is also central to the BUCK$$$ project, led by Kun, focusing on carbon capture and utilisation. This project, with €2.54m in funding, involves 13 partners from seven countries.

This innovative concrete arises from 'mineralised CO₂', which is similar to mollusc shells made of calcium carbonate, as well as materials derived from saltwork brine, desalination, and industrial wastewater. Both currently underused products are expected to become crucial in the cement and concrete industries, particularly in Italy.

Japan: Taiheiyo Cement will install a gas engine power system at its Fujiwara cement plant in Inabe-shi, Mie Prefecture. The system replaces the existing thermal power system at the plant, which uses petcoke. Construction is set to begin in 2025 and the facility will be operational by the end of 2026. The new system will reduce the plant’s CO₂ emissions by 130,000t/yr.

President and representative director Masafumi Fushihara said "Taiheiyo Cement positions the reduction of CO₂ emissions from its cement production as an important growth strategy and will work to continue to achieve carbon neutrality through various countermeasures and the promotion of further energy conservation."

Australia: Adbri has announced the early termination of its contract to supply quicklime to aluminium producer Alcoa, ending in April 2024 instead of the original plan for six months later. This decision is part of an amendment to meet changing demand. The news comes amid Adbri's ongoing review of its Western Australia lime operations and follows Alcoa's recent production curtailment at its Kwinana refinery. Adbri previously supplied to three Alcoa alumina refineries in Western Australia, but the number was reduced to one in 2021. 

Adbri is also in the process of finalising a US$2.1bn buyout with Irish company CRH.

China: Anhui Conch Cement's turnover was US$19.6bn in 2023, up by 6.8% year-on-year from 2022 levels. Sales of 42.5 grade cement contributed US$8.46bn (43% of turnover), down by 12% year-on-year. Meanwhile, sales of commercial concrete grew by 25% to US$313m (1.6% of turnover). Overall, the producer’s net profit fell by 33% to US$1.48bn.

Anhui Conch Cement commenced a share buyback programme for up to US$83m-worth of its listed stock in November 2023. At the end of the year, it had repurchased 0.3% of its shares.

India: UltraTech Cement says that the Competition Commission of India has approved its proposed acquisition of Kesoram Industries’ cement business. The Business Standard newspaper reported that the demerger of the business from Kesoram Industries into UltraTech Cement is scheduled for November 2024. The deal has an enterprise value of US$914m.

Switzerland: Holcim launched a share buyback programme on 18 March 2023. The programme, totalling Euro1.03bn, will run until the end of 2024. Share cancellation is scheduled for approval at the group’s annual general meeting in May 2025. Holcim plans to finance the buyback from its existing cash reserves. It says that it remains committed to retaining a strong investment grade credit rating.

US: Furno Materials completed an oversubscribed US$6.5m seed funding round on 13 March 2023. Subsequently, the start-up unveiled plans for its Furno Brick carbon-neutral modular cement plant, which can use a variety of gaseous fuels. The plant scales on demand, drastically reducing the barrier to entry for local or small-scale cement production.

Furno CEO Gurinder Nagra said “At Furno, we have the ability to produce ordinary Portland cement now, to adapt to a range of gas-based fuels and materials innovations as they emerge and to meet demand where it exists, while still abiding by a shifting regulatory landscape. Our mission is to go the distance by innovating at the heart of cement production and operating as a complement to other technological developments in the cement space. Our cement far exceeds ASTM International standards, a bare-minimum quality threshold. While most companies tout meeting these standards and stop there, we have continued to refine our process and are on target to surpass the even higher commercial requirements set by significantly-sized customers eager for our solution.”

India: ACC and Ambuja Cements' Geoclean has launched two new facilities for sustainable waste management. The Ambuja Marwar pre-processing and co-processing facility in Rajasthan can convert 220,000t/yr of refuse into alternative fuel, while the ACC Jamul co-processing facility will process an additional 120,000t/yr.

The Ambuja Marwar facility, in collaboration with the Ambuja Marwar Farmer Producer Organisation, aims to source 50,000t/yr of agricultural waste from local farmers. This initiative will also increase the plant's thermal substitution rate to 15%. Similarly, the ACC Jamul facility will enhance its thermal substitution rate to 10%, reducing CO₂ emissions through the co-processing of waste in the cement kiln.

Italy: Heidelberg Materials Italy, formerly Italcementi, has entered into a seven-year supply agreement with Ox2. Under the deal, Ox2 will sell up to 70% of the energy generated at the Stornarella wind farm in Foggia. The farm was developed in partnership with Nuveen Infrastructure.

The Stornarella wind farm will be constructed in 2024. Once operational, it will provide an average of 37 - 51GWh/yr of clean energy from 2025 to 2032. Nuveen Infrastructure has purchased the wind farm, which will feature six turbines with a total installed capacity of 27MW and an estimated output of 73GWh/yr.

Stefano Gallini, CEO of Heidelberg Materials Italy, said "Energy is a fundamental component of our industrial process and represents one of the main levers of decarbonisation for the entire cement sector. The electrical component can also contribute significantly to this purpose, and we have identified reliable partners like Ox2 and Nuveen to accompany us on this journey."
