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.”

New Zealand: Neocrete has entered a partnership with major cement manufacturers, including Cemex, Heidelberg Materials, CRH, Titan, Cementos Argos and Ultratech Cement to promote its new Activator product aimed at reducing the amount of cement required in concrete. The product uses volcanic ash or residual ash from industrial processes to cut the amount of cement required by 40% to 50%, according to the company. Neocrete aims to replace cement completely, resulting in carbon-free concrete, by 2027. The new product will be submitted for life cycle assessment once a new pilot plant in Mt Wellington is operational. The plant is valued at US$2m and will produce 0.12Mt/yr of cement, to meet 10% of New Zealand’s demand.

Co-founder Zarina Bazoeva said "We don't need to produce the whole volume of cement. We activate the concrete chemically with a small catalyst at 3kg compared to 100kg of cement. So, we can scale fast."

Switzerland: Holcim has entered a partnership with Kibag and Oxara for the production and distribution of Oxacrete Oulesse, a cement-free binder developed by Oxara. This new product reportedly aims to supply up to 10% of Switzerland's annual concrete market. Oxacrete Oulesse is made with materials from deconstruction, offering a low-carbon alternative to traditional cement.

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.

US: Heidelberg Materials North America has finalised award negotiations with the US Department of Energy's (DOE) Office of Clean Energy Demonstrations. The Mitchell cement plant in Indiana will receive US$300,000 to begin the first phase of its decarbonisation project, part of a broader initiative of up to US$500m in DOE funding to support full-scale carbon capture, transport and storage developments. The Mitchell cement plant has tripled its previous production capacity, with this project aiming to capture and process about 2Mt/yr of CO₂.

Chris Ward, president and CEO of Heidelberg Materials North America, said "This critical milestone of bringing our project under award with the US Department of Energy is a significant step in building the first full-scale application of carbon capture and storage for the cement industry in the US.”

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.”

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."

Austria: Alpacem will invest €50m to modernise its Wietersdorf plant, including a new cement grinding plant, reportedly capable of saving up to 21,000t/yr of CO₂ and reducing electricity consumption, according to the Kronen Zeitung. The plant is scheduled for completion and commissioning in 2027. In the future, a new cement silo plant will also be built in the Görtschitztal valley, directly connected to the railroad.

Florian Salzer, technical director at Alpacem Zement Austria said "With this new project, we are investing in a sustainable future and laying the foundations for energy-efficient and environmentally conscious cement grinding."

Managing director Lutz Weber added "Alpacem has a clear goal: CO₂-neutral production by 2035. To achieve this ambitious goal, we need a package of measures and a concrete path."

Philippines: Holcim Philippines will invest US$6.5m to upgrade its La Union plant and increase the use of alternative fuels and raw materials to 40%. The project will be implemented by Sinoma CBMIPH Construction and will be completed by late 2025, reports the Manila Bulletin.

Nicolas George, Holcim Philippines president and CEO, said the investment aims to reduce CO₂ emissions, promote recycling, support local waste management and provide income for northern Luzon farmers, who will supply biomass residues as alternative fuels.

General manager Zeng Youbing of Sinoma CBMIPH Construction said “This marks the third collaboration between Sinoma CBMIPH and Holcim Philippines since 2021. We are honoured to contribute to Holcim Philippines' decarbonisation and sustainability goals.”
