UK: N+P Group announced that investment has been approved for its new 5t/hr research and development pilot line at its Hartlepool site. The installation will separate biogenic fractions from hard-to-process waste, including municipal solid waste and material from materials recovery facilities and other processing sites. The output will be a cleaned, high-biogenic alternative fuel, with biogenic content expected to exceed 70%. N+P aims to deliver the first volumes from its facility in the first quarter of 2026.

Italy: Federbeton, which represents the cement and concrete industry, has signed a memorandum of understanding with Assocarta, the association of paper, cardboard and pulp producers, to develop synergies in circular economy and decarbonisation initiatives.

The agreement aims to recover paper industry waste as a resource for reducing CO₂ emissions in cement production. Recycled waste and sludge will be used to produce solid fuel recovered (SRF). The protocol includes joint technical discussions to identify suitable recovery conditions, cooperation in securing national and EU funding and engagement with public authorities to improve regulatory frameworks.

Federbeton president Stefano Gallini said “If decarbonisation is a systemic challenge, achieving this goal necessarily requires collaboration and shared commitment. The agreement with Assocarta stems precisely from this awareness and is a concrete tool to accelerate the path towards carbon neutrality. Replacing fossil fuels with solutions like SRF represents an immediate opportunity for the environment, the community and the country's energy independence. It is a lever already widely adopted in Europe, where the average substitution rate is 56%. In Italy, we still stand at 26%, due to inconsistent application of regulations and cultural mistrust.”

There have been a few sustainability-related news stories to note recently in Japan. Firstly, the Renewable Energy Institute (REI) released a report on decarbonisation pathways for the cement industry. Then, this week, the Japan Cement Association (JCA) held a press briefing on the sector’s work towards net zero and it released production and sales data. Finally, on a connected note, a speaker from Sumitomo Osaka Cement gave a presentation on recycling gypsum wallboard for cement production at last week’s Global Gypsum Conference.

The REI’s report is similar to other roadmaps published by cement associations around the world. The differences with the Global Cement and Concrete Association (GCCA) targets are worth pointing out though. The JCA is more conservative on the use of blended cements. It only specifies an aggregate CO₂ reduction target for 2030, limited to a greater use of alternative fuels (AF) and improved energy efficiency. Similarly, it forecasts clinker factors of 0.825 in 2030 and 0.80 in 2050, compared to the GCCA targets of 0.58 in 2030 and 0.52 in 2050. The report goes on to show that JCA members have higher Scope 1 and 2 emissions and a higher clinker factor than comparable multinationals, including Holcim, Heidelberg Materials and SCG. In summary the REI concludes that the local sector has been delayed in adopting blended cements, slow on using more renewable energy and continues to be reliant on coal.

The JCA’s update is more practical and outlines what can be expected. A benchmarking system for the sector was established in the 2025 financial year. The country’s emissions trading scheme will then start in the 2026 financial year. Companies that emit a three-year average of over 100,000t/yr of CO₂ will be subject to the scheme. The JCA is currently emphasising the sector’s role at the heart of the circular economy. It pointed out that it used just under 22Mt (5%) of the country’s total waste in 2024. It had an AF substitution rate of 27% in that year also. Other waste streams used included over 5Mt of blast furnace slag, over 6Mt of coal ash and around 1.7Mt of flue-gas desulphurisation (FGD) gypsum.

That last one ties into a presentation that Yuki Mihashi, Sumitomo Osaka Cement, gave at the recent Global Gypsum Conference, held last week in the Netherlands. He gave an overview of his company’s pilot testing of a carbon capture and utilisation process that uses waste gypsum wallboard and mineralises it to make an artificial limestone from cement plant CO₂ emissions. The current pilot plant is based in Osaka and was completed in June 2025. It consumes 10kg/hr of gypsum and can produce around 5.8kg/hr of calcium carbonate. Gypsum wallboard professionals at the event had previously expressed concerns about competition for raw materials from cement producers. If developments like this one progress to full scale deployment there could potential be repercussions in other industrial sectors.

Finally, the latest data from the JCA shows that cement production fell by 3% year-on-year to 32.99Mt in the first nine months of 2025 from 34Mt in the same period in 2024 . Overall sales followed a similar trend, although exports rose by 9% from 5.91Mt to 6.43Mt. This follows a general decline in cement production in Japan since the mid-1990s.

In summary, work on sustainability in the cement sector continues in Japan as it does elsewhere. The conservative approach to clinker factor forecasts is interesting to note compared to more optimistic projections elsewhere. A slower update of blended cements may explain some of this. Interestingly, Taiheiyo Cement said in June 2025 that it was expanding a hub in Saiki to export blended cements rather than using them domestically. On other issues, a current lower AF substitution rate compared to Europe offers one pathway for emissions reduction. The impending ETS may also galvanise action and investment. Expect plenty more sustainability news in the coming weeks ahead of the 30th Conference of the Parties (COP), which is set to take place in mid-November 2025 in Belém, Brazil.

The 1st CemFuels Asia Conference & Exhibition will take place on 2 – 3 February 2026 in Bangkok

The Deputy Prime Minister of Egypt met with representatives of the cement sector last week to discuss the local market. The key topics were prices, increased production capacity and restarting suspended production lines. Then this week it was revealed that the government was preparing to issue two new cement plant licences by the end of 2025. So, what’s been happening in the local sector?

Readers may recall that the Egyptian government tackled overcapacity issues by way of cement production quotas back in 2021. This solved the immediate problems at the time but, since then, there has been a growing problem with local producers focusing on export markets to the detriment of the domestic market. For example, there was a shortage of cement reported in mid-2024 due to a shortage of trucks. Large quantities of these were being used, it transpired, to transport cement to neighbouring Libya. For more on this read Global Cement Weekly #760.

The price of cement peaked earlier in 2025. At this point the government took action by limiting cement exports to no more than 30% of a company’s production volume and by abolishing the quota system. It later reviewed the status of eight idle production lines in an effort to get them running again. Prices subsequently eased according to local media reports. Before the changes, the Cement Division of the Federation of Egyptian Industries said that the country had a production capacity of 76Mt/yr from 46 lines. Domestic consumption was estimated at 46Mt/yr and exports at 20Mt/yr giving a utilisation rate 87%. Note that this export figure is 30% of the total production of the country as a whole. For the first half of 2025, production increased by 24% year-on-year to 30.7Mt from 24Mt in the same period in 2024. Exports rose by 11.5% to 9.7Mt from 8.7Mt. However, data from Al Arabiya Business shows that exports fell by 25% in May and June 2025 following the government action. Production grew by 16%.

Vicat’s financial report for the first half of 2025 reported that export sales volumes in Egypt represented over 50% of the local subsidiary’s total sales volumes. It also noted that the domestic price surpassed the export price during the reporting period. Titan Group said that its local business had experienced an ‘impressive turnaround’ due to a construction boom in the country. It said that its plants operated at ‘high capacity’ with an alternative fuels (AF) thermal substitution rate of around 40%. It added that it was intending to expand storage capacity to support growing export volumes. By contrast, Cementir endured a tougher trading period due, in part, to less exports following technical problems related to the restart of a local production line.

A source quoted by Al Arabiya from the Export Council for Building Materials noted that there had been a ‘significant’ decline in exports to several major markets, including Libya, Lebanon, the US, Ivory Coast and Ghana. That anonymous source also warned that, if the problem with the domestic market could not be resolved quickly, then the sector risked losing export markets where reconstruction work was taking place. These comments were mirrored by Adam Khalil, a Building Materials Sector Analyst at Al Ahly Pharos Securities, who told local media this week that the anticipated reconstruction of Gaza presented benefits for Egypt-based construction and building materials companies. In particular, he noted the proximity of Sinai Cement to the Gaza Strip. Unfortunately, at the time of writing, the latest ceasefire between Gaza and Israel appears to have been breached.

The other part of the government action has been focusing on increasing AF substitution rates. At the meeting with the Deputy Prime Minister this month the stated aim was to reduce production cuts. To this end, a report on the number of waste recycling plants was reviewed and compared to the requirements of each cement plant. The government intends to set up ‘practical implementation mechanisms’ to maximise the usage of AF. Energy sources have been a particular bugbear for the cement sector in Egypt historically as the government has encouraged producers to switch fuels from time to time.

The wider economy in Egypt continues to face headwinds. Cementir, for example, in its half year report said that the country’s economy was “...being held back by high inflation, devaluation, rising energy costs, pressure on manufacturing industries and a revision of the state budget with the suspension of infrastructure projects.” However, the International Monetary Fund (IMF) upgraded its growth forecast for Egypt in 2025 and 2026 in mid-October 2025. The decision by the government to cap exports of cement and cut the production quota marks a serious change since 2021. It is clearly watching the situation closely. The timing from roughly in the middle of the year should make the effects clear to see in the annual reports in early 2026. We will wait until then.

This week we covered Capitol Aggregates’ order of an alternative fuels (AF) system from ATS Walter USA. The story is notable because it is an AF project for a cement plant in the US. Thermal substitution rates (TSR) of AF in the US have typically been lower than in the European Union (EU), but this could be changing.

The order was confirmed publicly at the end of September 2025. The subsidiary of ATS Group will supply a solid AF metering and conveying system to the integrated plant in San Antonio, Texas. The system will include a moving floor receiving station, chain belt conveyors, a screen and a separator, dosing equipment, an air-supported belt conveyor and an injection system. ATS Walter says that, by the end of 2026, it will have supplied four AF projects in North America. As an aside, Capitol Aggregates also mentioned in the press release that it “...views sustainability as essential to long-term success.” This sentiment is backed up by the fact that the plant built an early commercial carbon capture unit in the 2010s!

Data from the American Cement Association (ACA) revealed that the AF TSR in the US reached 16% in 2023 from 14.6% in 2022. This compares to a 58% rate in the EU in 2022. It is also worth noting that, in the US the share of gas in the cement industry energy mix rose from 25% to 31%. The ACA attributed this change to a falling price of gas. It added that the coal and petroleum share of the fuel mix fell to its lowest level since 1974. The point here is that the energy mix used by cement plants changes over time regardless of sustainability trends.

Research by LEK Consulting estimated that 60 of the 87 cement plants in the US had a TSR of below 20% in 2023. 39 of these were believed to have a TSR of under 5%. It summarised that hazardous waste and tyre-derived fuels have tended to predominate in the US compared to refuse-derived fuel (RDF) in the EU and elsewhere. LEK went on to say that its research suggested that a quarter of cement plants in the US were likely to install an AF feeding system in 2024 or 2025. This is likely to be the highest rate of AF uptake in the US cement sector to date.

The ACA reckons in its sustainability roadmap that with the right policies and regulations the country’s AF TSR could reach as high as 50%. Its policy suggestions include: reduce permitting barriers to use of so-called non-hazardous secondary materials (NHSM) fuels in industrial manufacturing; treating waste-to-industrial energy as valid recycling use; building robust recycling infrastructure and markets that incentivise the use of non-recycled material streams as industrial AF; community education and support for use of low carbon AF; and increasing the use of NHSMs to divert these materials from landfills. This can be mostly summarised as supporting the uptake of RDF through better permitting and building up the infrastructure and markets for it. LEK also identified the same issue. It called for the adoption of landfill reduction targets or zero-landfill policies by commercial and industrial waste generators. However, LEK believes that, even if this were done, current sources of high-quality RDF in the US would not be able to increase the TSR to even 20%.

News from Capitol Aggregates and others about AF projects in the US are encouraging. If LEK’s research is indicative then a step change in the TSR in the country’s cement sector is already underway. The beauty of AF usage is that it can both potentially cut fuel costs and reduce CO₂ emissions. It won’t be easy as new supply chains for refuse byproducts are built and utilised. Yet, as the ACA is advocating, it is possible and worthwhile.

The 1st CemFuels Asia Conference will take place in Bangkok in February 2026 and the 19th Global CemFuels Conference will take place in September 2026 in Geneva

India: Recycling equipment manufacturer Fornnax Technology has launched the R-MAX3300, its largest secondary shredder, at IFAT India 2025 in Mumbai on 14 October 2025. The machine is designed to process low-density waste streams such as municipal solid waste, commercial and industrial waste, bulky waste, legacy waste, wood waste and construction and demolition waste. The R-MAX3300 produces refuse-derived fuel (RDF) and solid recovered fuel (SRF) with particle sizes between 30 and 50mm.

Director and CEO of Fornnax Technology Jignesh Kundaria said “With the rising challenges of waste management in India and globally, this machine is not just a product; it’s a powerful tool for change. We engineered it to handle the most difficult waste streams with unparalleled efficiency, turning what was once considered unusable waste into a valuable resource. It directly addresses the urgent demand for effective, large-scale shredding technology that can support cement kilns and waste-to-energy facilities in achieving the desired output.”

According to the company, India currently generates over 160,000t/day of municipal solid waste. Simultaneously, the global industrial shredder market is expected to grow at a 5-6% CAGR, driven by stricter recycling regulations and increasing waste generation.

Bolivia: The municipal government of Santa Cruz de la Sierra has signed an agreement with Itacamba Cemento to recycle thousands of end-of-life tyres (ENDTs) into alternative fuel for cement production, according to the El Deber newspaper. The initiative was implemented through the Municipal Waste Management Company (Emacruz).

Under the agreement, discarded tyres collected from landfills will be transformed into thermal energy for use in Itacamba’s cement kilns, reducing waste and fossil fuel consumption. The tyres will be incinerated at temperatures exceeding 1400°C, with monitoring and gas-capture systems employed to prevent harmful emissions.

Mayor Jhonny Fernández said “We guarantee the responsible disposal of thousands of tonnes of tyres that would otherwise cause pollution or become breeding grounds for diseases like dengue. This is our tangible contribution to a healthier environment and better quality of life for our citizens.”

Itacamba Cemento general manager Marcelo Morales said “Co-processing is a globally recognised waste management method that complies with the waste hierarchy. Our kiln enables the complete and safe destruction of non-recyclable materials.”

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.

France: Cement producer Eqiom has inaugurated a €2.5m pilot station for the continuous injection of alternative fuels at its Rochefort-sur-Nenon plant. The new facility enables the injection of wood fines - treated wood residues sourced from local sawmills - directly into the kiln at a rate of 5000t/yr.

The facility has reduced its coal use from 30,000t/yr to 8000t/yr. Currently, more than 70% of the plant’s kiln fuel comes from alternative sources, with the site now targeting 80%. Since the 1990s, the plant has successively used liquid chemical waste, animal meal and solid recovered fuels (SRF), which together accounted for 50,000t in 2024. Eqiom is also developing new cement types with lower clinker content by incorporating more pozzolans, as part of its broader decarbonisation efforts.

Pierre Bernard, Eqiom’s head of cement manufacturing, noted that national cement production fell from 20Mt/yr in 2022 to 15Mt/yr in 2024, equivalent to 1960 levels, due to a decline in construction activity.

Bulgaria: Zlatna Panega Cement, part of Greece-based Titan Group, has achieved a 65% rate of thermal substitution of fossil fuels with alternative fuels for four consecutive months. The company’s 5MW solar plant supplies between 11% and 13% of its energy needs.

General director Adamantios Francis said “We have achieved a historic success for our plant. With this, we prove that we are committed to sustainable development and are ready to lead the industry towards a greener future.”

Titan Group’s long-term strategy includes cutting energy consumption by 58% compared with 2020 levels and reducing direct net CO₂ emissions to 500kg/t of cement. At Zlatna Panega, CO₂ emissions in 2024 were 839kg/t of clinker, while electricity-related emissions fell by 38% year-on-year.
