Sweden: Cementa is running trials on a pilot water treatment plant in the File Hajdar limestone quarry near its Slite cement plant in Gotland. The pilot plant has been running since September 2022 and the subsidiary of Germany-based Heidelberg materials describes the first results as ‘promising.’ The cement company plans to build and pay for a full-scale water treatment plant at the site. Engineering and design company AFRY has been collaborating with Cementa on the project.

Matilda Hoffstedt, the manager of the Slite cement plant, said “We can contribute to greatly strengthening the public water supply here in northern Gotland. The results from the pilot project are extremely promising and we see that a new water plant would really make a difference to the water supply throughout the year.”

Cementa started work on the water project in 2021 with a feasibility study and plans for the pilot. The entire feasibility study is expected to be completed in the summer of 2023 and the goal is to be able to put a full-scale water plant into operation in 2027. However, Cementa says that it needs a long-term permit for its mining operations in Gotland in order to invest in the project. The cement producer has faced opposition to renewing its permit at the site since 2021. A perceived threat to the area’s drinking water supplies has been a repeated concern made by groups against continued quarrying in the area.

India: Operators of limestone mines in Karnataka's Chamarajanagar District have suspended quarry operations indefinitely in protest against the Karnataka state government's increased licensing royalties and rules requiring drone surveillance. The companies also demand that the state government cease to implement new policies affecting them. The Times of India newspaper has reported that the strike has impacted a total of 10,000 jobs, both at quarries and downstream in the building materials and construction sectors.

Philippines: Republic Cement has won seven awards at the Presidential Mineral Industry Awards 2023. The producer’s Bulacan cement plant won the Platinum Achievement Award, while its Batangas, Iligan and Teresa plants all claimed Quarry Operations (Non-Metallic) Awards. The Bulacan plant also won the Best Forest Mining Award in the Non-Metallic category, in which the Iligan plant was second runner-up. Lastly, Bulacan cement plant won the Safest Mine (Non-Metallic) Award.

Republic Cement’s CEO Roman Menz said "Throughout our 67 years of service towards building the nation, Republic Cement has always been deeply and wholly committed to responsible mining. It is through responsible mining and our daily commitment to safety and sustainability that we are able to support robust communities and a thriving environment, towards a greener and stronger republic."

India: Purvanchal Cement plans to invest US$24m in cement acquisitions and new grinding capacity construction projects before 2026. Under the plans, the producer will double its cement production capacity to 1Mt/yr. The Economic Times newspaper has reported that the plans include the establishment of a grinding plant in West Bengal and a second new plant with an associated quarry in northern Assam.

Purvanchal Cement operates the 0.5Mt/yr Kamrup grinding plant in Assam.

Sweden: The Land and Environmental Court has granted Cementa a four-year permit to continue mining operations in Slite on Gotland. The latest temporary permit was set to expire at the end of 2022. Both the Environmental Protection Agency (Naturvårdsverket) and the county administrative board of Gotland recommended rejecting Cementa’s application earlier in 2022. Prior to this the central government extended the cement company’s mining licence by one year from late 2021.

The subsidiary of Germany-based Heidelberg Materials said that it viewed the latest four-year permit as a ‘bridge’ until it is able to secure a long-term permit. It is aiming to submit an application for a 30-year permit in 2023.

Colombia: Cemex has announced the launch of the Tunjuelo Circularity Centre at its former Tunjuelo quarry near Bogotá. Having rebuilt parts of the 50m-deep quarry with demolition waste, Cemex will now work on its ecological restoration, while continuing to receive excavation waste for reconstruction of the ground. It will meanwhile divert demolition waste deliveries for recycling in aggregate production. In Bogotá, Cemex has launched an initiative for urban construction partnerships in collaboration with local authorities. It will also collect municipal solid waste (MSW) there for use in its cement production and collect its used plastic cement bags for recycling in building materials production.

Cemex’s Colombia and Peru president Alejandro Ramírez said "This is a pioneering model for Cemex in the construction materials industry globally, which we aim to position as a benchmark for circularity within the sustainable development of large cities in Colombia and the world. A piece of land that supplied materials for Bogotá's development for decades has received construction and demolition waste for its redevelopment and was transformed into a green area to the south of the city, an epicenter of the circular economy and an opportunity for urban development for the capital city of Colombia." 


New Zealand: The Global Cement and Concrete Association has welcomed Fletcher Building’s concrete division as its first member from Oceania. Scoop News has reported that the concrete’s division’s business spans the entire concrete value chain, including 26 limestone and aggregates quarries and 80 ready-mix concrete batching plants. Its cement subsidiary Golden Bay Cement operates the 0.9Mt/yr Portland cement plant in Whangārei, New Zealand.

Fletcher Building concrete division CEO Nick Traber said "Fletcher Building firmly believes we can play a significant part in a carbon zero and circular future. Our Golden Bay EcoSure cement is one of the lowest-carbon cements in the world already, with 13 - 22% less embodied carbon than imported products. We believe having access to the global research and knowledge from the GCCA will help us improve this further and continue to lead Australasia in best practice decarbonisation of the built environment."

Sri Lanka: INSEE Cement and the International Union for Conservation of Nature and Natural Resources (IUCN) have signed a memorandum (MoU) of understanding to extend their global biodiversity management partnership until 2026. Projects include quarry restoration, wildlife rescue and release and field surveys of the Koggala and Aruwakkalu mangrove restoration sites and Unawatuna manmade coral reef.

INSEE Cement's environment and corporate social responsibility manager Rohan Lakmal said "Biodiversity is one of the fundamental pillars of INSEE's Sustainability Ambition 2030. Our partnership with IUCN enables INSEE Cement to meet our own ambitious sustainability targets, while also creating more awareness of the general decline in Sri Lanka's biodiversity, and the urgency to do our part to conserve our natural habitats."

US: Lehigh Hanson plans to stop cement production at its integrated Permanente plant near Cupertino in California. The subsidiary of Germany-based Heidelberg Materials plans to use the site as a distribution centre and to continue some quarry work, according to the Mercury News newspaper. The cement plant was originally opened in 1939 but it stopped clinker production in 2020.

US: The National Mining Association has named Titan America's Pennsuco, Florida, quarry as winner of its Sentinels of Safety 2022 large quarry safety award. The quarry operated for 432,000 man hours without a single lost time incident during 2021.

Titan America's senior vice president Walter Reed said "The team at our Pennsuco Quarry demonstrates yet again that a fully embraced and entrenched safety culture will inevitably form the foundation for a long-term successful, sustainable, and extremely productive operation."

The 2022 award is the Pennsuco's second consecutive and eighth overall Sentinels of Safety win.
