India: Ramco Cements has commissioned a 3000t/day integrated cement line at its Ramamasamy Raja Nagar cement plant in Tamil Nadu. Projects Today News has reported that the plant runs on renewable energy from a captive wind farm, and recycles 90% of water used in production.

Ramco Cements produces Ramco 53 Infra Super cement at the Ramamasamy Raja Nagar plant. The product allows for lower cement and admixture content to be used in the production of concrete structures.

Europe: The European cement industry association, Cembureau, has welcomed the enactment of the Nature Restoration Law, which aims to restore ecosystems through binding targets in line with the EU Biodiversity Strategy. The European Commission says that the law provides a framework to 'secure the things nature does for free, like cleaning our water and air, pollinating crops and protecting us from floods,' as well as to help limit climate change to +1.5°C.

In a joint statement with other extractive industry bodies, Cembureau told the EU that member states' national restoration plans should take into account industry efforts to plan and implement nature restoration, that member states should protect pioneer species in line with the Nature Directives Species Protection Guidelines' definition of temporary nature and that restoration efforts outside of designated Natura 2000 areas should be addressed on a case-by-case basis in recognition of sectoral specificities.

Colombia: Cemex says that its Santa Rosa cement grinding plant is the first unit in its South, Central America and the Caribbean (SCAC) region to attain water self-sufficiency. The plant independently meets its water requirements using a 9000m³ reservoir, constantly replenished thanks to rainwater, runoff, and water circulation devices. The move aligns with the company's Water Management Roadmap, part of its Future in Action program. The achievement takes Cemex closer to its 2030 target of reducing freshwater consumption in its cement operations by 20%.

Canada: A study led by Douglas Geoffrey in Calgary, Alberta, has patented a method of producing cement from calcium carbonate precipitated in the carbonation of brine. The method mixes the mineral with magnesium oxide and cures it to form cement.

Geoffrey noted that the brine may derive from multiple industrial processes, including fossil fuel and potash production, geothermal power generation and desalination.

Europe: Cemex has launched its latest packaging design for its Vertua reduced-CO₂ product range at the Low Carbon World exhibition in Paris, France. The new design incorporates products' scores across five 'sustainability attributes:' emissions reduction, energy efficiency, conservation of water, recycled content and design optimisation. Cemex will now deploy the design across Europe by June 2023.

Cemex's Europe, Middle East and Africa regional president Sergio Menendez said “Cemex is attuned to the need to focus on all aspects that can make a product more sustainable - not just achieving a lower carbon footprint. With the updated classification system for Vertua, customers can now more easily identify which of our products leverage the cutting-edge technology and innovation that will enable them to overcome the challenges they are currently facing in construction and renovation." Menendez concluded "The enhanced Vertua brand represents a more ambitious and stronger approach: from a group of low carbon products to a family of products and solutions that encompass more sustainable attributes and contribute to our company vision of building a better future.”

Pakistan: Bestway Cement has ignited the kiln of Line 1 of its Mianwali cement plant in Punjab. The line has a capacity of 2.3Mt/yr. The Pakistan Observer newspaper has reported that it increases the producer's cement capacity by 18% to 15.3Mt/yr and brings its total number of production lines to eight. The Mianwali cement plant is equipped with a 20MW solar power plant and will run on 50% renewable energy. It also has a 9MW waste heat recovery (WHR) plant, an air cooled condenser (ACC) system and a rainwater harvesting system.

Bestway Cement CEO Lord Zameer Choudrey said "It's a great day for the company. Our new greenfield production line at Mianwali has been set up in a record time, despite various hurdles and supply chain disruptions caused by Covid-19."

Mexico: Cemex has reviewed its global sustainability and financial performance during 2022 in its Integrated Report 2022. During the year, the group reduced its specific CO₂ emissions by 9% from 2020 levels and by 30% from 1990 levels. It achieved a target of US$1bn-worth of investment in strategic projects over a period begun in 2020. Projects included the execution of water optimisation plans at 20% of Cemex sites in high-water stress areas. Cemex co-processed 27Mt of waste as alternative fuel (AF) in its global cement production - 67 times greater than its own non-recyclable waste footprint - and achieved an AF substitution rate of 35%. Meanwhile, the group also reduced its cement's clinker factor to 74%. Its Vertua reduced-CO₂ concrete range accounted for 33% of its concrete sales. During the year, Cemex launched the world's first net zero, fully electric heavy concrete mixer truck.

In 2022, Cemex recorded sales of US$15.6bn, down by 12% year-on-year, and reduced its debt to US$408m.

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.

Peru: Cemento Gloria subsidiary Cemento Yura's Yura cement plant has allegedly been the source of intermittent dust emissions, water contamination and destructive vibrations during its 50 years of operation. In May 2022, local authorities declared four houses uninhabitable due to cracks in walls and roof collapses. Local people have attributed the damage to the vibrations from the Yura cement plant's activities. In November 2022, local water supply is unavailable for over 40 minutes every day, allegedly also due to the plant's operations.

The La República newspaper has reported that Yura residents have launched a protest against the alleged environmental mismanagement outside of the company's plant.

Saudi Arabia: Yamama Cement has commissioned its second cement plant, with 20,000t/day in capacity across two clinker lines. The producer invested US$1.25bn in the plant's construction, which was carried out by Germany-based ThyssenKrupp. The facility is equipped with seven raw materials crushers, a 3.7km-long limestone conveyor belt, 110,000t of storage capacity, four Quadropol roller mills, two Dopol preheater towers, two Polro rotary kilns, two Polytrack clinker coolers, three 100,000t clinker silos, four Polycom high-pressure roller mills, six 22,590t and 25,000t cement silos and 22,000m³
in water storage basins. The new plant is situated in the eastern Arabian Desert, 80km from Riyadh.

Yamama Cement also operates the 6.4Mt/yr Al Karj Cement plant, 70km from Riyadh.
