Europe: In 2023, 29.7Mt of slag entered the built environment in building materials in the EU and the UK. 20.3Mt (68%) of the slag was granulated blast furnace slag, of which 18.3Mt (90%) was ground for use in cement production, with the other 2Mt (10%) serving as aggregates. The remaining 9.4Mt of the slag was steelwork slag, of which 600,000t (6.4%) was used in cement and concrete production, with the rest used for roadbuilding.

Between 2000 and 2023, slag substituted for 752Mt of limestone, clay and sand in clinker production and for 405Mt of aggregates across the EU and UK construction sectors.

Thomas Reiche, chair of the European slag association EuroSlag and managing director of the FEhS Building Materials Institute, said "Despite the tensions on the European steel market, ferrous slags were once again able to make an important contribution to resource conservation, climate protection and the circular economy in 2023."

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.”

Europe: The European Commission (EC), in coordination with the UK Competition and Markets Authority and the Turkish Competition Authority, launched unannounced antitrust inspections of additives and admixtures producers in ‘several’ countries. The EC said that the inspections form a preliminary step in an investigation of suspected anticompetitive practices.

France: Ireland-based Ecocem has entered into a new agreement with Saint-Gobain's France-based concrete subsidiary POINT.P. Under the agreement, Ecocem will supply its ACT alternative cement for use in POINT.P's precast and ready-mix concrete production. Ecocem said that the partnership is an opportunity for it to develop and market new low-carbon binders.

Ecocem executive director Olivier Guise said "This partnership with POINT.P is a natural extension of the alliance announced with the Saint-Gobain Group in October 2022. The shared objective is to accelerate the widespread deployment of low-carbon cements in France, both in the ready-mix concrete and precast concrete markets. By paving the way for the replacement of current traditional cements with ACT technology, our partner POINT.P has a real opportunity to meet its ambitious carbon reduction targets by 2030. We are firmly committed to this partnership and to working with a partner who shares our ambitions for rapid decarbonisation of the construction industry."

Ecocem is 25% owned by France-based Saint-Gobain.

Europe: 12 decarbonisation-focused companies from across the European cement and concrete sector have launched the Alliance for Low-Carbon Cement & Concrete (ALCC). The alliance has called on policymakers to change building standards to help low-carbon alternatives to enter the cement and concrete markets. It further said that green procurement and targeted financing instruments would help to reduce sectoral CO₂ emissions. It said that a progressive decline in clinker factor to 60%, 50% or 40% by 2050 will reduce CO₂ emissions by over 50%. The ALCC says that it is ready to lead the sector towards a swift, low-cost and viable decarbonisation pathway. Participants in the alliance include France-based Hoffmann Green Cement Technologies, Ireland-based Ecocem and US-based Fortera.

Fortera's Europe director Thierry Legrand said "Climate action is a global priority, and collaboration is essential to advancing emissions-reducing technologies and policies. This alliance represents collective action by scientists, engineers, entrepreneurs and environmental advocates to reduce CO₂ emissions from cement production."

World: Cemex has announced the launch of new bio-based admixtures which offer CO₂ emissions reductions of up to 70% compared to oil-based admixtures in its Asian, European and Middle Eastern markets. The range includes 10% reduced-CO₂ IsoPlast Bio, 20 - 30% reduced-CO₂ IsoFlex Bio plasticisers and superplasticisers and 50% reduced-CO₂ IsoFlow Bio high-performance superplasticiser technology, as well as CO₂-reducing IsoMill Bio grinding aids. The products will subsequently become available in other markets during 2023.

CEO Fernando González said “Innovation is at the core of our efforts to become a carbon neutral company and foster a more circular building materials industry." He added "Innovative admixtures aim to enhance concrete's sustainable attributes for our customers further.”

Europe: Italy-based Cementir has launched Aalborg InBind, a premixed white binder for ultra-high performance concrete (UHPC) applications. The supplier said that Aalborg InBind optimizes UHPC producers' costs by leveraging locally available materials.

Group chief sales, marketing and commercial development officer Michele Di Marino said “The specific needs of local projects have led precast concrete producers to look for their own UHPC by using local aggregates and chemical admixtures." He added "InBind is set to meet the market needs by providing a flexible and user-friendly binder solution.”
