Australia: Boral recorded sales of US$1.17bn during the first half of its 2023 financial year, up by 12% year-on-year from US$1.05bn during the first half of its 2022 financial year. Cement sales were US$128m, 11% of group sales. The producer’s net profit fell by 91% year-on-year to US$62.5m from US$715m.

During the half, Boral’s subsidiary Geelong Cement commissioned a new 0.8Mt/yr grinding unit at its 0.6Mt/yr Waurn Ponds grinding plant in Victoria. The group also upgraded the chlorine bypass system at its Berrima cement plant in New South Wales to support increased alternative fuel (AF) co-processing. Throughout 2022, Boral substituted 15% AF into its fuel mix.

India: Ramco Cements recorded revenues of US$674m during the first nine months of its 2023 financial year, up by 33% year-on-year from US$509m in the corresponding period of the 2022 financial year. Costs rose, including a 45% rise in the company’s raw material costs to US$110m from US$76m. This precipitated a 75% decline in the producer’s net profit, to US$23m from US$93.1m.

UK: Cambridge Electric Cement (CEC) has launched the two-year trial of its Cement 2 Zero project, aimed at scaling up production of its net zero-CO₂, demolition waste-based alternative cement. It aims to produce 20t of the material for use in a low-impact construction project. CEC’s method, developed at the University of Cambridge, is based on the conversion of demolition waste into a slag-forming material within a steel furnace.

Developer Julian Allwood said “By combining steel and cement recycling in a single process powered by renewable electricity, we could supplement the global supply of the basic construction materials to support the infrastructure of a zero emissions world and to enable economic development where it is most needed.”

India: Amplus Solar has secured a contract with JK Lakshmi Cement for construction of a 56MW solar power plant at the producer’s 1.7Mt/yr Durg cement plant in Chhattisgarh. The producer expects to eliminate 73,000t/yr of CO₂ emissions as a result.

JK Lakshmi Cement’s president Arun Shukla said "We support the country's vision to achieve net zero emissions by 2070. We have taken multiple steps to reduce both direct and indirect carbon emissions. Last month, for the first time in India, we deployed liquefied natural gas (LNG) trucks to transport raw material. Now, with the switch to solar energy at our Durg plant, nearly 80% of the plant’s energy requirements will be met renewably.”

Amplus Energy previously partnered with UltraTech Cement for a 50MW solar installation at one of its cement plants in 2019.

Sri Lanka: Tokyo Cement recorded sales of US$74.8m during the first nine months of the 2023 financial year, up by 25% year-on-year. Its cost of sales dropped by 2% to US$49.7m, while its profit for the period rose by 60% to US$2.35m.

Türkiye: OYAK Çimento and Taiwan Cement Company (TCC)s’ joint venture says that it has successfully restarted one of its Turkish cement plants following an earthquake on 6 February. The Netherlands-based joint venture said that two further plants remained at a standstill due to a regional power outage.

Two major tremors, of magnitudes 7.8 and 7.5 on the Richter scale, originated near Gaziantep in Türkiye’s Southeastern Anatolia Region. TCC immediately activated its Employee Care Plan to assist and arrange aid for employees and their families, dispatching 100 emergency kits by courier.

On 8 February 2023, rescuers had reported that 9460 people had died in the catastrophe, 6960 in Türkiye and 2500 in Syria.

Zimbabwe: South Africa-based PPC is reportedly considering selling PPC Zimbabwe for US$200m. The Zimbabwe Independent newspaper has reported that the group received an unsolicited offer from a local company.

PPC said “PPC’s board has a duty to assess any such approaches on their respective merits.”

US: The Department of Energy’s (DOE) Carbon Storage Assurance Facility Enterprise (CarbonSAFE) initiative has awarded funding of US$8.9m to Heidelberg Materials North America to study the subsurface geology for suitability for the storage of carbon dioxide at the Mitchell integrated cement plant in Indiana. The proposed project will geologically characterise several prospective reservoirs under the Mitchell plant for storage of more than 50Mt of CO₂ over a 30-year timeframe.

The award, which is managed by the National Energy Technology Laboratory, will be issued to the Illinois State Geological Survey at the University of Illinois (ISGS) as the prime contractor, with the company acting as a technical and industrial partner. Heidelberg Materials is contributing about US$1.5m in funding while ISGS will be contributing approximately US$0.6m for a project total of US$11.1m. The funding was part of a DOE initiative that generated nearly US$125m in funding for 10 projects to characterise suitability for carbon storage across the US.

Heidelberg Materials’ Mitchell cement plant is being upgraded with a new production line. Full production on the new line is anticipated to start in early 2023.

Senegal: China-based Sinoma CBMI Construction has commissioned a new production line at Ciments du Sahel’s Kirene plant near Dakar. The new 6000t/day line is intended to replace the plant’s existing third production line. Ciments du Sahel signed a contract with Sinoma CBMI to upgrade the plant in 2020.

US: Prometheus Materials has been awarded ASTM C129 certification for non-loadbearing concrete masonry units (CMU) and ASTM C90 for loadbearing CMUs for its bio-cement product. The company is commercialising a process to produce cement and concrete using microalgae.

Loren Burnett, the chief executive officer of Prometheus Materials, said “We are thrilled to have achieved these two foundational certifications as we proceed in full-force with our goal of decarbonising construction.” He added, “Prometheus Materials’ product is poised to change the future of construction, converting one of the most carbon-polluting industries to a low-carbon – and one day net-zero carbon – reality.”
