Asia: South East Asia's regional cement association, the ASEAN Federation of Cement Manufacturers (AFCM), has launched its AFCM 2035 Roadmap at its 46th Council Meeting at the Rizqun International Hotel in Bandar Seri Begawan, Brunei Darussalam. Under the roadmap, AFCM members will achieve a cumulative 38Mt reduction in CO₂ emissions by 2035. Efforts will unfold under four priority areas: promoting low-carbon cement, advancing the energy transition, maximising supplementary cementitious materials (SCMs) and adopting deep decarbonisation technologies. The council meeting served the members to help align their strategies, including through the proposed establishment of a unified emissions reporting system.

UK: Cemex UK has launched its partnership with The Pallet LOOP, with the first load of LOOP’s reusable pallets carrying Rugby Cement products from the company’s plant in Rugby. The FSC-certified pallets are designed for multiple trips and are supported by a national collection service offering customers €2.30–€4.61 for each pallet returned. The Pallet LOOP offers €2.30 for pallets that are damaged or dirty but repairable, and €4.61 for those returned in good condition. Cemex is the first cement producer to adopt the system.

The national sales manager for bagged cement at Cemex UK, Vicki Elliott, said “The Pallet LOOP’s business model mirrors our commitment to circularity with its award-winning reuse scheme. For decades, wasted and abandoned wood pallets have posed a real challenge across the supply chain. It is great to see such a fresh and dynamic approach effectively tackling the long-standing issue of single-use pallets. We look forward to expanding the service across the full Cemex portfolio in future roll outs.”

Managing director at The Pallet LOOP Andy Williamson said "The departure of the first load of Rugby Cement products on our LOOP pallets is another major milestone for us, for Cemex and for the wider building materials sector. By rewarding customers for every pallet they return, we’re making sustainability pay - helping companies in the construction industry lower costs while also reducing waste and their carbon footprint."

Saudi Arabia: Northern Region Cement Company (NRCC) has announced the signing of a contract for the construction of a US$8.7m, 20MW solar power plant in Turaif City. The plant will be supplied by Sinoma Overseas Development. The company says that the contract is in line with Saudi Vision 2030 and the company’s strategy to increase the use of renewable energy. Construction will take place over 10 months, with operations expected to begin in late 2026.

Sinoma Overseas Development will carry out the full scope of engineering design, procurement, supply and delivery during the contract duration time, in addition to civil construction, installation and commissioning.

US: ATS Walter USA has announced that it will supply Capitol Aggregates’ San Antonio cement plant with a metering and conveying system for solid alternative fuels (AF), with the aim to improve fuel handling and decrease CO₂ emissions at the plant. The system includes a DoseaFloor moving floor receiving system, chain belt conveyors, separator and screen, Doseahorse dosing equipment, Walt’Air air-supported belt conveyor and injection system. The project, to be completed by the end of 2026, will be ATS Walter USA’s fourth AF project in North America.

Renewables reportedly generated more power than coal in the first half of 2025. Energy think tank Ember put out a report this week, which showed that solar and wind generation also grew faster than the rise in electricity demand in the first half of 2025. Global electricity demand rose by 2.6% year-on-year, adding 369TW. Solar increased by 306TW and wind by 97TW. Both coal and gas generation fell slightly, although a rise in other fossil fuel generation slowed the decline further.

Tellingly, fossil fuel generation fell in both China and India. Indeed, China added more solar and wind than the rest of the world combined, cutting its fossil fuel generation by 2% or by 58.7TWh. In India, renewables grew at the expense of fossil fuels, but demand growth was relatively low at 12TWh. In the US and the European Union (EU) fossil fuel generation actually increased. In the US, this was due to demand growth outpacing new renewable power. In the EU, weaker wind and hydroelectric output led to a greater reliance on coal and gas.

Meanwhile, a separate report by the International Energy Agency (IEA), also out this week, predicts that installed renewable power is likely to more than double by 2030 even as the sector navigates headwinds in supply chains, grid integration and financing. The IEA forecasts that global renewable power capacity will increase by 4600GW by 2030, roughly the equivalent of adding the total power generation capacity of China, the EU and combined. Solar photovoltaic (PV) will account for around 80% of the global increase in renewable power capacity over the next five years, followed by wind, hydroelectric, bioenergy and geothermal. Solar PV is expected to dominate renewables’ growth between now and 2030, remaining the lowest-cost option for new generation in most countries. Wind power, despite its near-term challenges, is still set for considerable expansion as supply bottlenecks ease and projects move forward, notably in China, Europe and India. However, the IEA’s outlook for global renewable capacity growth has been revised downward slightly compared to 2024, mainly due to policy changes in the US and in China.

This is all very well but what does it mean for the cement sector? At face value, possibly not much anytime soon. Both Ember and the IEA are talking about domestic electricity generation, not industrial. Ember reckons that half the world’s economies may have already peaked in fossil fuel power generation, but usage rates are still high. Prices of fossil fuels may even subsequently come down - to the benefit of industrial users such as cement plants. Yet, carbon taxes should, in theory, discourage increased usage - if they are working correctly.

Market distortions should not be discounted though. Some readers may recall what happened with carbon credits in the earlier stages of the EU emissions trading scheme. Free carbon allowances, calculated during the boom years of 2005 - 2007 when production was maxed out, were far too much to cover production during the resulting economic crisis. The sale of extra allowances provided many plants with a nice little earner and did little to encourage decarbonisation. Carbon capture is likely to require large amounts of electricity, but cheaper energy from renewables may help.

However, take a look at renewable energy stories in the Global Cement website news so far in 2025 and there are nearly 30 solar-related and seven wind-related ones. Cement companies are busily adding renewable capacity to reduce the cost of their electricity. This week, for example, Equator Energy commissioned a 10MW captive solar power plant at Mombasa Cement’s Vipingo plant in Kenya. Last week, Southern Province Cement in Saudi Arabia signed a 25-year solar energy power purchase agreement for its Bisha cement plant. Lest one forget, Saudi Arabia was the largest exporter of crude oil among Organization of the Petroleum Exporting Countries (OPEC) members in 2023 at 6,659,000 barrels/day. If a cement plant in Saudi Arabia is investing in renewables, then one might suspect a change in the global energy mix is occurring.

Electricity accounts for around 12% of the energy demand at a cement plant. Nearly two-thirds of that demand comes from either grinding raw materials or cement. Then, as mentioned above, carbon capture is expected to increase the demand for electricity. One estimate reckons it will increase electricity consumption by 50 - 120%. Renewables are expected to bring down the price of electricity but demand will also grow.

So… expect more renewable projects linked to cement plants.

Vietnam: Industry leaders have argued that co-processing of non-recyclable plastic waste in cement kilns could be a scalable solution to advance Vietnam’s sustainability and circular economy goals. At a workshop held in Hanoi on 2 October 2025, the Norwegian Foundation for Scientific and Industrial Research (SINTEF) and the Royal Norwegian Embassy, in partnership with the Vietnam National Cement Association (VNCA), concluded the OPTOCE Project (‘Ocean Plastic Turned into an Opportunity in Circular Economy’), funded by the Norwegian government.

Norwegian Ambassador to Vietnam Hilde Solbakken said “Combating marine plastics and climate change is a top priority for Norway – both globally and in Vietnam. Through OPTOCE, we’ve seen how science-based solutions like co-processing can transform plastic waste into a resource that benefits the climate, the economy and communities.”

OPTOCE was originally launched as a regional initiative in five countries, including Vietnam, and later expanded to eight countries across Asia. The workshop featured several presentations and a panel discussion focusing on the legal framework, potential waste supplies, and the practices and challenges in implementing co-processing in Vietnam.

Dr Kåre Helge Karstensen, chief scientist and programme manager of OPTOCE, added that the initiative has proven co-processing to be both technically feasible and environmentally sound. “The next step is to move beyond pilots and integrate this solution into national policy frameworks to drive systemic change,” he said.

Dr Lương Đức Long, VNCA vice president, said Vietnam’s cement industry is already applying co-processing successfully. “Co-processing waste in cement kilns is a safe and effective solution. We hope the government introduces specific policies and incentives that support enterprises and technology transfer. If we join forces, co-processing will turn wastes into ‘black gold’ and cement factories into ideal co-processing hubs,” he said.

Vietnam’s cement plants, including INSEE’s Hon Chong facility in Kien Giang and Lam Thach Green Cement (QNC)’s plant in the north, have piloted this approach since 2021, achieving thermal substitution rates of 35–40%.

India: Noida International Airport (NIA) has become India's first large-scale project to utilise limestone calcined clay cement (LC3), a low-carbon alternative to traditional cement. In a statement, concessionaire Yamuna International Airport Private Limited (YIAPL) said LC3 was used extensively in the construction of the airport.

Developed for more than 10 years by researchers at IIT Delhi, IIT Madras, Swiss Development Cooperation, École Polytechnique Fédérale de Lausanne (Switzerland), Universidad de las Villas (Cuba), and Technology and Action for Rural Advancement (TARA), LC3 emits up to 40% less CO₂ than conventional Portland cement. It costs 25% less to produce, uses low-grade limestone and clays and requires lower energy for manufacturing while delivering comparable strength.

Senegal: The Ministry of Environment and Ecological Transition, in partnership with Cementis and with the support of the United Nations Climate Technology Centre and Network, held a workshop in late September 2025 to launch the national roadmap for decarbonisation in the cement industry. The initiative aims to reduce CO₂ emissions in cement production in the country by optimising industrial processes and adapting the energy sources used.

Croatia: Holcim has inaugurated the Kodeco investment at its Koromačno cement plant, with commissioning still ongoing, according to a Linkedin post by Region Head Central and East Europe, Simon Kronenberg. The project includes the installation of a new calciner, a chlorine bypass, and storage and transport systems for solid recovered fuel (SRF). Holcim said the investment marks a key step in enhancing the efficiency and sustainability of its operations in Croatia.

UK: Cemex UK has announced a partnership with The Pallet LOOP to roll out reusable pallets for its Rugby Cement products from October 2025. The company said that it is the first cement manufacturer to adopt the LOOP system. The initiative forms part of Cemex’s ‘Future in Action’ strategy to reach carbon neutrality by 2050. Initially, the LOOP pallets will be used for the core Rugby packed range, including Premium Cement (paper and plastic bags), High Strength and Sulphate, with expansion across the portfolio planned for later phases.

Vicki Elliott, national sales manager for bagged cement at Cemex UK, said “This is a significant step forward for the cement industry. We’ve supported The Pallet LOOP from day one, signing its charter back in 2022. Now, we’re proud to be the first in our sector to integrate this solution into our supply chain. It’s about doing the right thing, as simply as possible: reducing waste, cutting carbon and helping our customers make more sustainable choices.”

The Pallet LOOP addresses the construction sector’s reliance on single-use pallets, of which fewer than 10% are reused, generating over 250,000t/yr of wood waste, according to the company. The Pallet LOOP’s FSC-certified pallets are built for multiple trips and backed by a nationwide collection service that offers financial incentives for returns.
