Canada: CarbiCrete has installed new equipment at Patio Drummond's Drummondville plant for the production of concrete using its cement-free technology. The technology mineralises captured CO₂ for sequestration inside the product.

France: Saint-Gobain subsidiary Chryso has launched EnviroMix C-Clay, a new range of additives designed for the production of concrete using calcined clay cement. Chryso says that the product enables concrete producers to reduce their CO₂ emissions by 50% by displacing ordinary Portland cement (OPC).

Canada: CarbiCrete has entered into a new ‘financing collaboration’ with US-based social media group Meta for its installation of CarbiCrete equipment at Canal Block’s Drummond concrete plant in Ontario. Climate consultancy 3Degrees will verify Canal Block’s CO₂ emissions reductions per the terms of the financing collaboration.

Saudi Arabia: Al Kifah Readymix & Blocks (KRB) has secured accreditation for its CarbonCure CO₂-injected concrete. Gulf Construction News has reported that the Saudi Standards, Metrology and Quality Organisation accredited CarbonCure as a Type-S additive following year-long tests. Canada-based CarbonCure Technologies licensed the technology to KRB. The producer uses CarbonCure in its Congreen range of reduced-CO₂ cements.

KRB General Manager Nigel Harries said "This milestone marks KRB as the first company in the Kingdom to utilise this innovative solution.”

Spain: Cemex España has purchased two additional electric concrete mixer trucks (e-mixers) for its fleet. Alimarket-Construcción News has reported that one e-mixer will operate at the San Fernando ready-mix concrete batching plant in Madrid and the other at the Sant Just ready-mix concrete batching plant in Barcelona.

UK: Russell Roof Tiles has installed a 165kW solar power plant as part of a €22.2m upgrade to its Burton concrete roof tiles plant in Staffordshire. Energy company Alt-Group supplied the solar power plant, which is equipped with Solis Inverters’ energy storage inverters. The upgraded Burton plant also features wash water recycling.

Russell Roof Tiles has signed a pledge to achieve Scope 1 and 2 CO₂ neutrality by 2040.

US: Novel concretes developer Greencraft has made a patent application for a new method of CO₂ mineralisation using a microporous material containing mineral oxides, like slag. Global Warming Focus News has reported that the method also works for natural hyaloclastite, bottom ash, fly ash, volcanic ash and lava.

Greencraft said that its method marks an ‘improvement’ in current techniques for sequestering CO₂ in alternative materials.

UK: Switzerland-based Neustark has partnered with Holcim subsidiary Aggregate Industries to launch the UK’s first mineralisation plant in Greenwich, London. The small-scale mobile plant will sequester CO₂ in recycled concrete produced using fines recovered from construction and demolition materials (CDM). The plant is situated at an existing Aggregates Industries CDM recycling site. A large-scale plant with a sequestration capacity of 1000t/yr of CO₂ is due to follow in early 2025.

Neustark CEO Valentin Gutknecht said "Neustark and Holcim have been working together almost since the founding of Neustark five years ago. 1Mt of CO₂ durably removed from the atmosphere in 2030 – that’s our ambition. We’re already well underway towards the megatonne goal. Our strategic partnership with Holcim represents a significant part of this roadmap. It will be a true catalyst to further scale up the permanent carbon removal impact that we generate in the next few years.”

Aggregate Industries CEO Lee Sleight said that the partnership would turn London into ‘one of the world’s largest urban mines.’ He said “This isn’t just a great carbon removal innovation but a great circular economy innovation, where we are taking what was once a waste stream and reusing it, saving us from digging up virgin materials in the first place."

Neustark has so far sequestered 2500t of CO₂ in circular concrete for use in further construction.

Greece: Titan Cement Group subsidiary Interbeton has launched Velter, a circular, 30% reduced-CO₂ ready-mix concrete. The product comes with a Type III environmental product declaration from Eurocert.

Director of concrete operations Christoforos Voulgaris said "This new product line gives engineers, architects, builders and investors the opportunity to differentiate their projects with improved durability and a meaningful contribution to mitigating the effects of climate change.”

Saudi Arabia: City Cement subsidiary Nizak Mining Company has entered talks with UK-based calcined clay producer Next Generation SCM about a possible joint venture. The proposed joint venture will build a reduced-CO₂ concrete plant in Riyadh, with further such plants to follow. TradeArabia News has reported that commercial-scale production will commence in mid-late 2025, with an initial target capacity of 350,000t/yr.

City Cement CEO Majed Alosailan said "This joint venture is a significant step in our commitment to the continued growth of Saudi Arabia as a global materials and infrastructure hub. Not only will it support domestic job creation, it will also dramatically improve accessibility to critical low-carbon materials that we will soon be able to export around the region. As the materials transition continues to accelerate, finding solutions that support the Kingdom’s infrastructure ambitions hand in hand with sustainability targets is essential to realise the opportunity ahead."

Next Generation SCM CEO Christian Husum said "There are over 4bn people who live in urban areas right now, and that is going to increase by 2bn over the next 30 years. This is a massive, global building project, which is equivalent to building an additional New York City every month. Those cities will also need the infrastructure to cope with an influx of people and there is no way to do that without concrete. There is also no way for our planet to cope with concrete production at that scale unless we find a way of producing it without generating enormous amounts of carbon emissions. Now, there is a way. This joint venture will put the process into practice to bring about a revolution in how we build everything from stadiums to skyscrapers in Saudi Arabia, the Middle East and then the world.”
