The Indonesian Cement Association (ASI) has warned that cuts to the Nusantara Capital City project had reduced cement sales so far in 2025. Yet also this week the ASEAN Federation of Cement Manufacturers (AFCM) launched its 2035 AFCM Decarbonisation Roadmap. Here is a round-up of recent news from the cement sector in Indonesia.

ASI data shows that local cement sales volumes fell by 2.5% year-on-year to 51.9Mt in the first 10 months of 2025 from 53.2Mt in the same period in 2024. Cement production decreased by 5.6% to 52.9Mt. Lower demand was reported in Kalimantan and Java. However, it rose in Sumatra and Nusa, in part, due to road construction. Sadly, Sumatra has been badly affected by floods this week. National cement exports grew by over 20% to 1.1Mt. The ASI is currently hopeful that a government-backed home renovation programme might stimulate demand.

The general picture can be seen above in Graph 1. The local cement sector has generally had a capacity utilisation issue since the mid-2010s. Domestic sales started to catch up but the Covid-19 pandemic disrupted the market. Meanwhile, exports of cement and clinker have been steadily rising since 2014. These are dominated by clinker exports, with the single largest destination being Bangladesh. Other major targets include Taiwan and Australia. The country’s relatively low consumption of cement per capita suggests that the utilisation rate will grow over time.

The local production market is dominated by state-owned Semen Indonesia (SIG) (with a 48.5% share), followed by Indocement (29.1%), Conch Cement Indonesia (7.1%) and Cemindo Gemilang (6.6%). SIG’s sales volumes in the first nine months of 2025 roughly follow the general trend reported by the ASI with local sales down by 1.8% year-on-year to 27.5Mt and exports up by 25.3% to 5.1Mt. The group’s sales revenue and earnings before interest, taxation, depreciation and amortisation (EBITDA) dropped by 3.8% to US$1.52bn and 23.8% to US$198m respectively. Indocement’s revenue fell by a similar rate. Both companies anticipate a modest recovery in 2026.

Something to note from SIG’s financial results and related discussions in 2025 (and earlier) has been its approach to marketing and selling its cement brands in a highly competitive environment. It says it changes its brand mix in different regional locations with varying combinations of market leaders with premium pricing and so-called ‘fighting brands’ with competitive pricing. Yet, eco-brands received a mention in addition to the other two groups in the third quarter report analysts’ discussions suggesting an appetite for potentially lower-clinker cements in a developing market such as Indonesia.

This leads to the second Indonesia-related news story of the week: the 2035 AFCM Decarbonisation Roadmap. The plan intends to reduce net CO₂ emissions from the cement sector in the region by 16% to 190Mt/yr from 228Mt/yr in 2020. 58% of this reduction will be achieved through the use of alternative fuels, 33% via the use of low-carbon cements and 9% through the use of renewable energy sources. Work towards carbon capture, utilisation and/or storage (CCUS) is starting with the aim of supporting capture pilots in the region and planning towards CO₂ transport and storage networks. Similarly, the roadmap urges producers to identify and prepare to use new secondary cementitious materials such as calcined clay and construction and demolition waste.

The race between capacity building and market share has been a familiar one in coverage of the cement market in Indonesia in recent decades. Provided the main companies can endure the competition, it looks set to continue, while demographic trends indicate the need for continued investment. Otherwise more market consolidation is to be expected when the utilisation rate dips too low. What is new though are the higher levels of blended cements and the changes this brings to the market. This can be seen above in the marketing strategy of SIG and the regional decarbonisation strategy. Similar trends are happening everywhere but the effects on a highly competitive market could be pronounced. Particularly if those government-backed schemes that the sector anticipates promote it.

The Global CemFuels Asia Conference will take place on 2 - 3 February 2026 in Bangkok

Lithuania: Scientists at Kaunas University of Technology (KTU) have developed methods to convert discarded textiles into alternative fuels and cement additives to reduce waste. Efforts focus on reducing the clinker content of cement and CO₂ output.

Dr Raimonda Kubiliute of the KTU Faculty of Chemical Technology said “The cement industry, especially clinker firing processes in rotary kilns, contributes significantly to environmental pollution. This is why researchers are actively seeking ways to reduce the amount of conventional cement in cement-based mixtures by replacing it with alternative binders or fillers.”

KTU found that polyester fibre from waste textiles, when added to concrete at 1.5%, increases compressive strength by 15-20% and improves freeze-thaw resistance. Ash from thermal treatment of textiles at 300°C in an inert atmosphere can replace up to 7.5% of ordinary Portland cement and increase strength by up to 16% under curing conditions. The findings are part of the ‘Production of Alternative Fuel from Textile Waste in Energy-Intensive Industries (Textifuel)’ project between KTU and the Lithuanian Energy Institute.

Dr Kubiliute said “This technological solution not only reduces CO₂ emissions during cement production but also provides an innovative and environmentally friendly approach to textile waste management.”

India: The Global Cement and Concrete Association (GCCA) India said that the cement industry has installed 1.8GW of renewable energy capacity and aims to add 5GW more by 2030, according to Platts. Around 3% of electricity used comes from renewables and 11% from waste heat recovery. GCCA India said that the average alternative fuel thermal substitution rate (TSR) in the sector is approximately 6%, although some plants have successfully achieved TSRs of more than 20%. It also said that there are developments in the installations of hybrid energy systems, which provide 24/7 electricity for the sector.

Blended cement accounts for 73% of production, and India has reportedly begun producing limestone calcined clay cement. Research is also underway into other low-clinker alternatives. According to a March 2025 report by GCCA India and The Energy and Resources Institute, the industry aims to achieve net-zero emissions by 2070. CRISIL forecasts that the sector will add 160-170Mt/yr of grinding capacity between the financial years 2026-2028, which run from April to March, driven by a healthy demand outlook and high capacity utilisation.

Global: The Global Cement and Concrete Association (GCCA) has launched its ‘Cement and Concrete Industry Net Zero Action and Progress Report 2025/6’, which reports a fall by 25% in CO₂ intensity of cementitious products since 1990 and sets out policy measures needed to accelerate decarbonisation. The report was launched at COP30 in Belem, Brazil.

The report highlights more than 60 decarbonisation projects across alternative fuels, alternative raw materials, carbon capture, renewable energy and recycled concrete. Examples include Fletcher’s Golden Bay plant and JSW’s Nandyal and Shiva plants. Publicly announced projects are collated and made available to see on the GCCA/LeadIT green cement technology tracker. The document also calls for policies enabling non-recyclable waste use in kilns, wider adoption of blended products, national carbon pricing mechanisms and the use of construction demolition waste as recycled raw materials.

GCCA president and Heidelberg Materials chair Dominik von Achten said “Our industry is collaborating and innovating across every aspect of our production - finding new ways to work and deploying exciting technologies that are already making a genuine step change. However, to achieve the industrial scale transformation that our world needs, we cannot do it by ourselves - our industry needs the support of governments, policymakers, stakeholders, and our allies across the built environment right now.”

GCCA chief executive Thomas Guillot said “The breadth of activity we are seeing across our membership is truly inspiring, with great examples of projects and work across all decarbonisation levers, where enabling policies exist. Cement and concrete are essential materials for the world, but we know they are also essential to decarbonise. Despite our progress, we know that firm policy action across the world is fundamental to enabling us to accelerate our reductions.”

Brazil: Cimento Apodi said that it has recorded a 20% thermal substitution rate (TSR), avoided 1500t/yr of CO₂ emissions and invested more than US$4.7m in a new 5MW solar park. The producer has targeted a 25% TSR by the end of 2025.

It says it will increase renewable energy use through its solar park and a waste heat recovery system. Together these will supply 25% of its electricity demand by the end of 2025. The implementation of the cement mill optimiser (CMO), an artificial intelligence-based system developed with the Federal University of Ceará and the Titan Group, has increased mill productivity by up to 13% and installed capacity by 10%. The company is also developing gasifiers that can reduce emissions by up to 10% per tonne of cement.

The integrated Quixeré cement plant coprocesses byproducts such as tyres, cashew nut shells, açaí seeds, carnauba stalks and industrial waste from other sectors. All materials undergo sorting and characterisation to meet the parameters of particle size, moisture and calorific value.

Philippines: Holcim Philippines has signed an agreement with Prime Infrastructure Capital for the supply of refuse-derived fuel (RDF) to its cement plants in Bulacan and La Union. Under the deal, Prime Infra’s subsidiary Prime Waste Solutions (PWS) Pampanga will provide RDF produced from plastic waste converted into alternative fuels through co-processing technology, helping Holcim to reduce its reliance on traditional fuels.

Cara Peralta, market sector lead for waste at Prime Infra, said “It is rare to find like-minded organisations such as Holcim willing to partner with us and make investments in sustainable practices like RDF consumption.”

Emir Adigüzel warned that cement prices in Europe could triple under current decarbonisation policies. The director of the World Cement Association (WCA) made the comments at a conference in Germany this week. He noted that most of these carbon-related costs will be passed to consumers. His view is that carbon pricing will force price rises across the industry.

That cement prices will rise due to decarbonisation policies is not in itself news. This debate is really about how much and who pays. The WCA's latest analysis asserts that the cement sector will require investment of US$200bn by 2050 to fully decarbonise. Some progress has been achieved so far. Major cement companies reduced carbon intensity from an average of 700kg CO₂/t in 2019 to 640kg CO₂/t in 2023. Adigüzel’s argument is that carbon capture (CCUS) in the cement sector has its place only “if applied correctly.” His view is that these technologies will have a limited effect on global industry decarbonisation as the required investment per cement plant exceeds the capital cost of an entire cement plant. The WCA prefers to promote decarbonisation instead via energy efficiency, alternative fuels, reduced clinker factor and new technologies. That last one includes CCUS but is not limited to it also covering things such as electrification and heat storage. Note today’s news that India-based Adani Cement has ordered a RotoDynamic Heater from Coolbrook. Adigüzel also criticised the European Union’s Carbon Border Adjustment Mechanism (CBAM) in incentivising non-scheme exporters to reduce their carbon footprint, particularly given the expensive investments required.

Decarbonisation is going to be expensive and CCUS is the priciest part of this. Hence, cement producers are likely to consider taking as many measures as possible before implementing CCUS. That cement companies would pass on these costs to consumers also seems likely. The other obvious outcome is that consumers will simply use less cement where possible. Yet Adigüzel doesn’t address how net zero can be achieved with continuing clinker production without using CCUS. His pricing for CCUS is at the right scale though. As Boston Consulting Group (BCG) pointed out in 2024, the cost of CCUS looks set to increase cement prices from US$90 – 130/t to at least US$160 – 240/t by 2050. As well as the capital costs to build a CCUS unit, this includes the additional energy costs required and the price of transporting the CO₂ to a sequestration site. The first two large-scale Heidelberg Materials CCUS projects in Europe, for example, both connect to government-backed transport and sequestration schemes. BCG went on to posit that decarbonisation trends would create five archetypes of cement plants: export hubs and larger plants close to CO₂ storage sites; former export sites far from storage; import grinding hubs; and stranded assets.

Finally, Carbon Brief reported this week that CO₂ emissions in China continued to stay flat in the third quarter of 2025, suggesting a stable or falling trend since early 2024. The adoption of electric vehicles and declines from cement and steel production contributed to the picture in the latest quarter. Emissions from the production of cement and other building materials fell by 7% year-on-year in the third quarter of 2025. This was attributed to the ongoing real-estate contraction. Note that this decarbonisation trend in China has been created by market trends.

Expect plenty more sustainability stories everywhere over the next few weeks as the 2025 United Nations Climate Change Conference (COP30) started this week in Belém, Brazil. The GCCA will be present at a number of events including an update to the Brazil Cement Industry Roadmap on Saturday 15 November 2025

The Global FutureCem Conference on cement industry decarbonisation will take place on 21 - 22 January 2026 in Munich, Germany
