Mexico: The government says that if US-based Vulcan Materials continues to reject offers for land in Quintana Roo on which its Calica-Sac-Tun quarry is situated, then it will designate the land Protected Natural Area status. Reuters has reported that the government has previously offered US$328 – 383m for the property. Vulcan Materials has mounted on-going legal challenges worth US$1.9bn against the Mexican government over the previous closure of its operations.

Thailand: China-based intelligent dumptruck supplier Waytous has partnered with Siam Cement Group (SCG), as well as Thailand Advanced Info Service, Huawei, and Zhengzhou Yutong Mining Equipment, to develop full-scope automated operating systems for limestone mines. SCG will host a study at its Saraburi limestone mine in Central Thailand. The study will use Waytous’ driverless vehicles, supported by 5G, AI, cloud computing and new battery technologies.

Waytous CEO Chen Long "We've carried out two phases of unmanned mining research for this project and found the most comprehensive, efficient, and effective unmanned solution for cement mines in Saraburi.”

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.

Dominican Republic: Cemex is considering selling its subsidiary Cemex Dominicana according to Bloomberg. The Mexico-based group is reportedly working with JPMorgan Chase & Co on a potential divestment worth over US$1bn. Proceedings are at an early stage, with Cemex starting to talk to interested parties to assess potential interest.

Cemex has been operating in the Dominican Republic since 1995 when it acquired Cementos Nacionales. It runs the integrated 2.4Mt/yr San Pedro de Macorís cement plant. It also has ten concrete plants, three sea terminals, two aggregate quarries and a gypsum mine. It employs 1500 people directly. Cemex sold its subsidiaries in Costa Rica and El Salvador to Cementos Progreso for US$329m in 2022.

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.”

Spain: Residents of Cartagena, Murcia, have protested Cemex’s plans to begin mining pozzolan at new sites locally. The Murcia Plaza newspaper has reported that the protestors are calling for a mining ban, in line with their interpretation of the area’s Rural Area of Special Environmental and Social Sensitivity designation.

Mexico: The Mexican ambassador to the US is due to make US-based Vulcan Materials an offer of US$390m to sell a 2400 hectare parcel of land in Quintana Roo to the government. The land includes a disused limestone quarry and the Riviera Maya cement terminal, which is currently used by Cemex. The government's Ministry of the Environment ordered the closure of the quarry in May 2022, when it also banned Vulcan Materials from despatching limestone.

Mexican President López Obrador said that Vulcan Materials 'shouldn't reject the offer.' He added "We’ll buy everything from them, we’ll pay immediately and we’ll turn 2000 hectares into a natural protected area. They’ll be able to say "We’re contributing to stopping climate change." And we’ll only keep one part, to carry out an ecotourism development with a cruise ship pier.”

Associated Press News has reported that Vulcan Materials has filed a valuation showing the land to be worth US$1.9bn.

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.

France: Heidelberg Materials has announced plans for its CIRCO₂BETON concrete recycling project. It intends to build an industrial-scale selective separation unit at its Achères quarry near Paris. Here it will recycle demolished concrete by crushing it and separating it into its components: sand, aggregates, and recycled concrete paste (RCP). The recycled sand and aggregates will be reincorporated into new concrete.

The RCP will be transported to the Ranville cement plant in the Normandy region. There, a reactor for enforced carbonation will be installed to carbonate the RCP by exposing it to CO₂-containing exhaust gases from the kiln. The carbonated RCP acts as a carbon sink and will replace clinker in new low-carbon cement types. The project has the potential to reduce the CO₂ emissions of the Ranville cement plant by 20%.

CIRCO₂BETON is supported by the ‘Investment for the Future’ Program coordinated by the Ecological Transition Agency (ADEME). In addition, the Île-de-France region supports the selective separation plant at Achères through its zero-waste and circular economy plan. Subject to the funding, construction of both industrial pilots is scheduled to start in 2024 with production of RCP starting in 2025. The carbonation reactor is planned to be operational by 2026.

Nicola Kimm, the chief sustainability officer at Heidelberg Materials, said ”We are investing in a pioneering large-scale project based on innovative process technologies. Selective separation and CO₂ mineralisation are important levers to reduce the carbon footprint of our products. By closing the materials loop, we prove that concrete has the potential to be the most sustainable building product over its entire life cycle from production to recycling.”
