Japan: Taiheiyo Cement says it is progressing with its C4S project to develop a novel concrete imbued with CO₂ from direct air capture (DAC). The project is a collaboration with the University of Tokyo, with support from the Japanese New Energy and Industrial Technology Development Organisation (NEDO). Taiheiyo Cement says that concrete developed by the partnership aids faster CO₂ capture via DAC, increasing strength, confirmed seismic resistance and carbon neutrality per full life-cycle assessment.

Taiheiyo Cement says that the eventual certification of DAC-carbonated concrete will play a significant role in the decarbonisation of the Japanese construction sector.

Canada: Hyperion Global Energy has fired up its pilot Tandem Carbon Recycling System at Lafarge Canada’s Bath cement plant in Ontario. The system mineralises captured CO₂ to produce mineral components for alternative building materials. It has a capture capacity of 1000t/yr. The partners will test the Tandem Carbon Recycling System in producing Lafarge Canada’s 30 – 90% reduced CO₂ ECOPact concrete.

Lafarge Canada’s Eastern Canada regional president and CEO of David Redfern said "Our collaboration with Hyperion marks an exciting milestone in our decarbonisation journey and the advancement of our circular construction technologies. We look forward to advancing our net zero strategy by leveraging carbon utilisation technology like Hyperion's, enabling us to further reduce CO₂ emissions from our operations while at the same time producing innovative and sustainable building solutions."

Hyperion CEO Heather Ward said "Working together with an innovative partner like Lafarge on this exciting pilot project allows us to apply our proprietary carbon recycling technology to large-scale industries, and make an immediate, measurable reduction on carbon emissions. At the same time, we are advancing our vision to offer a scalable and affordable decarbonisation solution for industry, and a market-driven profit incentive on the cost of carbon removal."

Global: The Global Cement and Concrete Association (GCCA) has announced new collaborations between global cement manufacturers and technology start-ups, focusing on the development of low carbon concrete. Four start-ups—EnviCore in Canada, Queens Carbon and Chement, both in the US and NeoCrete in New Zealand—were part of the 2023 GCCA Innovandi Open Challenge and have now partnered with cement manufacturers. These partnerships aim to reduce the carbon footprint of concrete.

The startups will receive access to industry plants, labs and networks to fast-track their technologies. They will also demonstrate their progress on 6th June 2024 in Bangkok, Thailand, during the GCCA's CEO and Leaders Conference. The association continues its efforts under the 2050 Net Zero Concrete Roadmap, with 29 new start-ups shortlisted this year to work on carbon capture, utilisation and storage (CCUS) technology.

Sweden: Heidelberg Materials has won a contract to supply its evoZero net-zero concrete. product for the construction of the new Nobel Center in Stockholm. Heidelberg Materials says that its memorandum of understanding with the Nobel Foundation ‘symbolises an important link between science and the green industrial transformation.’ EvoZero concrete achieves its carbon neutrality through Heidelberg Materials’ use of carbon capture at its cement plants.

Jon Morrish, member of Heidelberg Materials’ managing board responsible for Europe, said “Together with the Nobel Center project, we aim to set a new standard for sustainable construction and pave the way for other future-orientated players. The collaboration enables us to combine the world of science and innovative solutions from our own sector such as evoZero in an exciting way.”

Switzerland: Carbon capture and storage (CCS) equipment developer and supplier Neustark says it plans to more than double the number of its CO₂ storage sites in Austria, France, Germany, Switzerland and the UK to 34 from 14. Neustark’s process turns mineralised captured CO₂ and existing mineral waste streams into useful limestone. Building materials producers lease Neustark’s storage sites to produce reduced-CO₂ alternatives such as recycled concrete. The sites currently have a total storage capacity of 5000t. Existing customers include Holcim.

Neustark CEO Johannes Tiefenthaler said “Neustark is scaling up rapidly, and we’re well on track to achieve our aim of permanently removing 1Mt of CO₂ by 2030. Our global goal is a series of reliable, region-specific CCS facilities that can be replicated anywhere, offering immediate sustainability benefits to local supply chains.”

US: A team from the Massachusetts Institute of Technology (MIT) has developed a new method to sequester CO₂ in concrete before curing it. The method is based on the addition of bicarbonate of soda, which reacts with cement to produce a calcium carbonate-calcium silicone hydrate composite. The Journal of Engineering has reported that the method adds the benefits of CO₂ mineralisation during production and casting, doubling the mechanical performance of early-stage concrete. It also eliminates the effects of carbonation reactions in cured concrete, which weaken the concrete by lowering its alkalinity, which accelerates the corrosion of rebar. The method has the potential to sequester 15% of CO₂ emissions from cement production.

The team said “The pre-curing capacity of concrete to sequester CO₂ has been largely underestimated and underutilised. Our new discovery could further be combined with other recent innovations in the development of lower carbon footprint concrete admixtures to provide much greener, and even carbon-negative, construction materials.”

Finland: VTT Technical Research Centre subsidiary Carbonaide has concluded its seed funding round, having raised funds worth Euro1.8m. Lakan Betoni, which produces precast and ready-mix concrete, led the funding, along with utilities provider Vantaa Energy. Carbonaide will use the funds to build an industrial pilot plant for its carbon neutral precast concrete product at an existing precast concrete plant in Hollola. The plant will bind captured CO₂ in the product at atmospheric pressure. The process generates 50% lower CO₂ emissions than precast concrete production using ordinary Portland cement (OPC). Suitable raw materials include ground granulated blast furnace slag (GGBFS), green liquor dregs and bio-ash. In trial production, the use of GGBFS gave Carbonaide's concrete a negative carbon footprint of -60kg/m³.

Other sources of loans and in-kind contributions included Finnish state innovation fund Business Finland.

Belgium: The EU Innovation Fund has awarded Euro4.5m to a consortium consisting of Prefer, gas provider Fluxys Belgium, lime producer Lhoist and carbonation technology developer Orbix. The collaborators are working on a project called CO2ncrEAT. The project will carbonate steel sector by-products with captured CO₂ from Lhoist's Hermalle lime plant to produce alternative building materials. CO2ncrEAT will be the first project to employ Orbix's innovative technique for the purpose. Fluxys Belgium's pipeline technology will convey the Hermalle plant's emissions over a distance of 2km to a Prefer concrete blocks plant.

The consortium said that it will use 12,000t/yr of CO₂ to produce 100,000t/yr of reduced-CO₂ concrete blocks. The use of alternative raw materials in the blocks will further reduce their carbon footprint by 8000t/yr.

Prefer managing director Raphaël Grimont said “As market leader, we must ensure the sustainability of our business by offering innovative and eco-friendly products to our customers. With the CO2ncrEAT project, our building materials will be produced through a sustainable and efficient process and based on local, circular raw materials. The Prefer masonry block of tomorrow will retain all the advantages of the traditional block, with the difference that it will benefit from a negative carbon footprint. We are proud to develop this exceptional project together with key industrial partners, while benefitting from the trust of the European, Belgian and Walloon authorities.”

Germany: Ireland-based CRH has agreed to sell its subsidiaries Opterra Zement and Opterra Beton to Thomas Gruppe. Thomas Gruppe expects to complete its acquisition of the businesses later in 2022. Opterra Zement owns the 1.4Mt/yr Karsdorf, Saxony-Anhalt, cement plant and 0.5Mt/yr Sötenich, North Rhine-Westphalia, grinding plant, the latter of which is closed. Opterra Beton operates the Neufahrn, Bavaria, ready-mix concrete batching plant.

Thomas Gruppe said "For years, we have been pursuing a steady and long-term growth course in the field of cement and precast and ready-mix concrete. In the cement segment, our competitive position improved significantly with the purchase of the Erwitte (North Rhine-Westphalia) plant in 2017. Together with the grinding plant in Dorndorf (Thuringia), we have achieved a significantly larger area coverage in Germany, and also in the Netherlands, and benefit from synergy effects." It continued "We would like to continue on this growth course. An opportunity like the one to take over the cement plant in Karsdorf does not come often. The Karsdorf plant, with its gigantic limestone deposits, its market position of well over 1Mt/yr of cement and its experienced team, enables us better to supply our customers, and to leverage improvement potential. In addition, Karsdorf is of sufficient size for us to implement CO₂ separation technology in its production of clinker for the Dorndorf grinding plant." Thomas Gruppe concluded "We are convinced that cement will become a clean building material and believe in its future."
