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.”

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.

South Korea: Ssangyong C&E has exported 30,000t of low-carbon limestone cement (Type IL) to the US, its first such shipment following three years of research and development, according to AJU News. The product reportedly has a reduced clinker content and maintains the same physical performance as general cement. The producer plans to export 200,000t to the US in 2024 and 600,000t in 2025.

A Ssangyong C&E official said "Currently, our country's national standards stipulate that mixed cement only uses slag, fly ash and pozzolan. In order to reduce carbon emissions in the future, conditions must be created where various types of eco-friendly cement, including limestone cement, can be used."

Germany: The University of Trier is transforming post-consumer materials into ‘ecological’ cement through a new research project that aims to find sustainable alternatives for the construction industry. The project involves using low-CO₂ industrial post-consumer materials as alternative cement binders, such as sludge from gravel and sand mining, as well as dust from quartzite extraction. The research will run for two years and is supported by the German Federal Environment Foundation.

Nigeria: Lafarge Africa has launched ECOPlanet Unicem, the country's first low-carbon multipurpose cement, from its Mfamosing plant in Cross River State. The new product is reportedly designed with over 30% reduction in CO₂ emissions. ECOPlanet will be available nationwide by the end of 2024.

US: Holcim US in Missouri will receive US$1.37m from President Biden's Inflation Reduction Act to support the reduction of climate pollution in manufacturing construction materials, as announced by the US Environmental Protection Agency (EPA). The grant is part of a broader effort to reduce emissions from the manufacturing industry and will aid Holcim's Environmental Product Declaration Accelerator Project.

EPA Region 7 Administrator, Meg McCollister, said "We commend Holcim for its work in advancing sustainable practices to reduce carbon emissions here in the Heartland and across our nation. Its innovative approach, supported by this grant, advances climate-friendly practices and sustainability in one of our nation's most important industries."

US: Vineyard Offshore has agreed to buy 2000t of cement from Sublime Systems, a Massachusetts startup planning a US$150m ‘carbon-free’ cement plant in the city. The cement will be used for turbine platforms and onshore civil works within the Vineyard Wind 2 project, aiming to reduce its carbon footprint. This agreement is contingent on the project's selection in upcoming solicitations.

Germany: Alcemy, manufacturer of low-carbon ‘Cem X’ cement, has raised US$10m to scale up its cement decarbonisation solution. The funding round will support research and development and Alcemy's entry into new markets, including the US, in 2024.

CEO Leopold Spenner said "With this additional nearly US$10m in funding and support from Norrsken VC, in addition to our first-round investors, we're paving the way to a low-carbon construction industry, one project at a time."

UK: Aggregate Industries has commenced civil construction at its new manufacturing facility and import terminal at the Port of Tilbury. This new grinding station and storage facility aims to be fully operational by 2026.

The project will allow the company to supply conventional, low-carbon and circular cementitious materials 24 hours a day from five loading heads, meeting growing demands for sustainable building materials. It includes investments in new plant equipment for manufacturing blended cements and lower carbon cement components, such as ground granulated blast furnace slag and materials from construction demolition.

US: Solidia Technologies has entered a technology licensing agreement with CalPortland. The deal grants CalPortland limited rights to use Solidia’s patents, which can reportedly reduce the carbon footprint of cement and concrete by up to 50%. The limited licenses will allow CalPortland to use the Solidia technology to develop low carbon solutions. CalPortland also purchased certain laboratory and plant assets from Solidia.

CEO of Solidia Technologies, Russell Hill, said "CalPortland's unwavering commitment to decarbonisation of the cement and concrete industries makes it a great partner for continuing the vast development and research advanced by Solidia more than a decade ago."
