Malaysia: A court has granted Associated Pan Malaysia Cement (APMC) the right to evict Buddhist monks from the Gunung Kanthan caves monastery in Hulu Kinta, Perak. The land is part of a site where APMC has leased 146 hectares of land for limestone extraction. New Straits Times News has reported that the producer operates quarries in Zones A and B of the site, but has yet to commence extraction from Zones C and D. Local authorities had previously given assurance that mining operations ‘would not disturb’ the monastery.

Monks from the Thudong tradition established the Gunung Kanthan caves monastery across two caves in Gunung Kanthan hill in the early 20th century. Today, it contains numerous artefacts and works of art.

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.

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.”

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.
