India: UltraTech Cement has obtained a $500m sustainability-linked loan from Sumitomo Mitsui Banking Corporation, State Bank of India, BNP Paribas and other lenders. Capital Market News has reported that the conditions for the loan align with UltraTech's 2050 Net-Zero Roadmap. Under the roadmap, the subsidiary of Aditya Birla Group aims to reduce its Scope 1 CO₂ emissions per tonne of cementitious material by 27% between 2017 and 2032, and to raise its reliance on renewables to 85% of its energy consumption by 2030.

UltraTech Cement previously issued sustainability-linked bonds in 2021.

UK: Material Evolution will launch the UK's ‘largest ultra-low carbon cement plant’ in Wrexham in October 2024, reports the Construction Enquirer. The new facility will produce 150,000t/yr of a cement that emits up to 85% less embodied CO₂ than Ordinary Portland Cement (OPC), according to the company. Material Evolution is the driving force behind the €9m Mevocrete project, funded by government-led Innovate UK, and utilises byproducts from the steel industry. Business co-founder Liz Gilligan said that Material Evolution aims to remove one gigatonne of carbon by 2040, while replacing OPC as the ‘go-to’ product for UK construction. The company plans to replicate and scale its production across the UK and Europe.

Chief science officer at Material Evolution and co-lead of the ‘Mevocrete’ project, David Hughes, said "Cement is a binder and what we’re looking at here is creating a net zero embodied carbon cement which is inherently more durable, which means our houses, infrastructure and transport highways would be transformed on mass industry scale, really tapping into a local and national picture of a net zero environment.”

Serbia: Lafarge Serbia is set to build a new cement plant in Ratari near Obrenovac, which will utilise 1Mt/yr of ash from the nearby Nikola Tesla B power plant as a raw material in cement production, reports Balkan Green Energy News. This €110m investment marks Serbia's first cement plant built next to a power plant to harness ash directly from the source and address the country’s problem of ash accumulation in dumps.

CEO of Lafarge Serbia Dimitrije Knjeginjić said "Fly ash cannot be used in the cement or concrete industry, or many other industries, without prior processing. This is exactly what the Ratari plant will be dealing with. We will grind, classify and select 1Mt/yr of ash to produce new construction materials."

Philippines: First Gen will supply electricity from geothermal sources to Holcim Philippines plants in Mindanao. Under the agreement, First Gen subsidiary Energy Development will provide 22% of the energy needs for Holcim's manufacturing facilities in Bunawan, Davao City, and Lugait, Misamis Oriental. This partnership is enabled by the Mindanao introduction of the retail competition and open access programme, allowing significant power consumers to select their electricity suppliers. Earlier in August 2024, Holcim announced an electricity supply agreement with Alsons Power to supply 80% of the energy needs for the two facilities.

First Gen president and chief operating officer Francis Giles Puno said "We are pleased to partner with Holcim Philippines to grow viably while decarbonising. It's not an easy journey to decarbonise and provide for a regenerative future. This requires collaboration not just through supplying power, but also through solutions that maximise and optimise electricity requirements and working to find a pathway towards net zero."

US: Fortera has raised US$85m in a funding round to increase its production of ‘low to zero-carbon’ cement, Bloomberg reports. New investors include Wollemi Capital, Saint-Gobain venture capital arm NOVA, Presidio Ventures and Alumni Ventures, alongside existing investors Khosla Ventures and Singapore state fund Temasek.

The startup, valued at US$355m, utilises a technology that captures CO₂ emissions from traditional cement production and converts them into a mineral form for low-carbon cement. Fortera's first industrial ‘green’ cement plant operates at CalPortland's facility in Redding, California.

China: Eaton and Langham hotels have collaborated with Green Island Cement to transform 8t of oyster shells into a sustainable cement alternative, sourcing 80% of the required limestone for cement.

Amie Lai Gor, general manager of sustainability at Great Eagle Holdings, parent company of the two hotels, said "We brought together like-minded partners to repurpose oyster shells as a sustainable raw material alternative for cement production. Our goal is to encourage more hotels and restaurants to participate, diverting more discarded oyster shells from landfills through upcycling.”

Raymond Cheung Wai-man, division manager at Green Island Cement, highlighted past challenges of separating the shells from impurities like mud and residual meat, which initially deterred the project.

Lai Gor added that future plans include working with local universities to assess the carbon reduction potential of substituting limestone with oyster shells in cement production. Despite the higher costs—tenfold compared to traditional limestone—Cheung believes that scaling up could significantly lower expenses.

Latvia/Lithuania: Capsol Technologies has won a contract to carry out two CapsolGo carbon capture demonstration campaigns at the Brocēni cement plant in Latvia and the Akmenės Cementas cement plant in Lithuania. Both plants are owned by Germany’s Schwenk Zement. Following a feasibility study earlier in 2024, the demonstrations will run from the fourth quarter of 2024 to the fourth quarter of 2025 and will showcase the CapsolEoP capture technology.

Philipp Staggat, chief product officer of Capsol Technologies, said "CapsolEoP offers lower energy consumption with higher CO₂ concentration than competitive technologies, and the capture cost for cement owners is reduced further as it doesn't require external steam supply. We are looking forward to demonstrating our technology on Schwenk's cement plants.”

CEO of Akmenės Cementas, Arturas Zaremba added "In collaboration with our clients and stakeholders, we are dedicated to addressing these challenges. The implementation of CapsolEoP technology at our Latvian and Lithuanian plants is a testament to our commitment, marking a significant stride towards the goal of capturing over 1.5Mt/yr of CO₂.”

Mexico: A second industrial byproducts processing line has been inaugurated at the Cemento Cruz Azul plant in Tepezalá, Aguascalientes. The new facility, which cost US$8.5m, will create 100 jobs and convert over 66,000t/yr of post-consumer materials into energy for the cement plant's processes.

Víctor Manuel Velázquez Rangel, president of the board of directors of Cooperativa Cruz Azul, said "This is the result of joint work, teamwork and a shared vision with the State Government, which has always been concerned about the carbon footprint, sustainability and the environment. With this project we leave testimony of our great commitment and demonstrate that innovation and technology can go hand in hand with the preservation of the environment."

Canada: Canada-based carbon capture, utilisation and storage (CCUS) company Carbon Upcycling has been admitted to the Portland Cement Association (PCA). This new membership aims to support industry efforts to achieve carbon neutrality. The US Department of Energy previously announced over US$1.2bn in funding for PCA member companies to launch decarbonisation projects under recent federal initiatives. Carbon Upcycling has been developing a commercial CCS system at CRH’s cement plant in Mississauga.

PCA president and CEO Mike Ireland said "We are thrilled to have Carbon Upcycling join us as a member of the PCA, given our shared commitment to sustainability. Their efforts are helping the cement industry increase circularity and advance the industry's commitment to achieving carbon neutrality."

CEO of Carbon Upcycling Apoorv Sinha said "The most effective and credible pathway to decarbonising the cement industry is through strategic partnerships and collaboration with long-time industry leaders in the infrastructure sector. Joining the PCA underscores our commitment to advance sustainable practices and substantially reduce carbon emissions. We look forward to forging a low-carbon, resilient future with our fellow members."
