Japan: Cement plants consumed 70Mt-worth (50%) of total limestone shipments in Japan during the 2023 financial year, which ended on 31 March 2023. Nikkei Industry Summary News has reported that limestone is the only mineral resource for which Japan is self-sufficient. However, it reported that the country’s cement sector is exposed to effects from the global coal market. Producers expect that the rising price of coal from China may diminish their earnings due to increased costs.

Uganda: A joint venture of Sunbird Quarry Moroto and China-based West International Holding Cement has begun building its upcoming Moroto cement plant. New Vision News has reported that the plant will cost US$1.2bn and produce cement from locally sourced limestone. The Uganda government said that the plant will generate jobs and help to lower the local price of cement.

Indonesia: Hongshi Indonesia Tonga Cement has commissioned the first phase of its new cement plant in East Kutai, East Kalimantan. At this phase of its development, the plant has a capacity of 4Mt/yr. It holds 1Bnt of limestone reserves and is equipped with a 50,000t marine terminal. The plant is situated over 250km away from the site of Indonesia’s upcoming new capital city, Nusantara, also in East Kalimantan. Hongshi Indonesia Tonga Cement plans to subsequently raise the plant’s capacity to 8Mt/yr.

Spain: Cemex España has bought two new quarries near Madrid. The producer said that the quarries will strengthen its limestone reserves. It added that they include ‘all necessary elements’ for it to increase its services to the Madrid market.

Cemex’s Europe, Middle East, Africa and Asia regional president Sergio Menéndez said “These acquisitions strengthen our existing network and enable us to better serve a growing market with high-quality, sustainable and circular products. We are excited to be part of Madrid’s growth, which contributes to improving the quality of life of its residents and setting an example for more sustainable and circular cities.”

US: Heidelberg Materials North America has reached an agreement with the administration of Santa Clara County to decommission its quarry in the county, near Cupertino. Silicon Valley News has reported that the quarry historically supplied limestone for cement production at Permanente cement plant, which came offline in April 2020. The county administration says that the deal signals that it has achieved its aim to ensure final closure of the Permanente plant.

Heidelberg Materials North America spokesperson Jeff Sieg said that the company is ‘pleased to formalise our agreement not to restart the kiln at our Permanente cement plant.’ He continued "We remain focused on working collaboratively with the community and other stakeholders on the development of a long-term strategy for the property, so that it can continue to provide value in the future.”

India: Ramco Cements plans to invest a total of US$91.3m towards growing its capacity during the 2024 financial year, which ends on 31 March 2024. Its planned investments consist of US$15.8m in an expansion to its Haridaspur grinding plant in Odisha and US$75.5m in the acquisition of land in Bommanalli, Karnataka, on which to establish a limestone mine.

During the previous financial year, which ended on 31 March 2023, Ramco Cements invested US$215m in capital expenditure.

India: Ramco Cements has concluded an agreement to acquire limestone reserves in Andhra Pradesh’s Nandyal District from Prism Johnson. The Hindu newspaper has reported that Prism Johnson will transfer a mining lease for 663 hectares of land to Ramco Cements. The parties expect to conclude the transaction by the end of July 2023.

Prism Johnson had previously planned to build an integrated cement plant on the reserves, but said that this no longer suited its priorities.

US: In 2022, Fortera began building a 15,000t/yr-capacity plant to produce its low-carbon cementitious material, Fortera Reactive Calcium Carbonate (RCC), at CalPortland's Redding cement plant in California. The commercial-scale plant will produce a reactive form of calcium carbonate using CO₂ from the kiln of the 600,000t/yr cement plant. Fortera's process converts 1t of limestone into 1t of Fortera RCC by capturing and mineralising CO₂ from the cement plant's kiln. Fortera cement production emits 60% less CO₂ than ordinary Portland cement (OPC). The 15,000t/yr plant will operate at 20 times the scale of previous pilot tests. The Redding Record newspaper has reported that 15 workers will be employed at the site.

Former Redding cement plant owner Lehigh Hanson formed an agreement with Fortera to collaborate on the low-carbon cement plant project in March 2021. The plant subsequently switched ownership to Martin Marietta Materials in October 2021, before CalPortland bought it in July 2022.

China: Asia Cement has launched its 2050 decarbonisation strategy, entitled 'Net-Zero Carbon Emissions By 2050 - Asia Cement Advanced Deployment.' The strategy consists of multiple pillars, namely 'alternative fuels,' 'reducing cement's clinker factor,' 'increasing renewable energy reliance' and 'carbon capture.'

During 2022, Asia Cement reduced its limestone, clay, iron and sand consumption by 266,000t, its coal consumption by 17,000t and its gypsum consumption by 56,000t year-on-year. This eliminated 95,100t of CO₂ emissions throughout the year, according to the producer.

Philippines: Metal and ores producer Global Ferronickel Holdings (FNI) plans to invest in clinker production operations. The company has indicated that it will also begin producing limestone to supply any clinker plants that it builds. The Manila Bulletin newspaper has reported that FNI's plans also include new ventures into value-added processing, including through the establishment of a ferronickel processing plant and nickel matte processing facility.
