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.”

Canada: Concrete block producer Canal Block has integrated CarbiCrete’s cement-free concrete production technology at its Port Colborne plant in Ontario. CarbiCrete’s technology produces concrete from steel slag. The integration at the Port Colborne plant commands US$2.24m-worth of funding from the global innovation cluster NGen, towards a total project cost of US$5.97m.

CarbiCrete CEO Chris Stern said "We are tremendously grateful for NGen's continued support, which is helping Canada position itself as the undisputed world leader in low carbon concrete."

Canal Block president Durk Bylsma said "Canal Block has had a long history of developing sustainable products for the masonry industry. We are excited to partner with CarbiCrete to bring this truly revolutionary technology to market and further our commitment to be an ecologically and socially responsible manufacturer."

Spain: Switzerland-based Holcim has acquired a majority stake in precast concrete systems producer Arterpref. Holcim says that Artepref’s smart design systems combined with its own range of low-carbon and circular solutions will help Spain’s fast-growing construction sector to build better with less.

Holcim’s Europe regional head Miljan Gutovic said “Fully in line with our strategy, this expands our range of innovative and sustainable solutions in high-growth markets.”

Czech Republic: Cemex Czech Republic has successfully commissioned its Prague-Libuš ready-mix concrete batching plant in Prague, following an upgrade. The upgraded plant can now process five types of cements and admixtures, including Cemex’s Vertua reduced-CO₂ concretes and recycled aggregates. Cemex Czech Republic has installed two recycled aggregates production plants at the site to process residual concrete.

Cemex’s vice president materials, Central Europe, Ruediger Kuhn said “Our plant in Libuš forms an important part of our operation in the Czech republic, thanks to its interesting location in the wider centre of the capital and in the immediate vicinity of the planned construction of the Prague Metro D line. We are therefore very pleased to have this site reopened following a considerable investment.” He added “The development at this site confirms Cemex’s determination to offer its customers superior quality products while also meeting its sustainability objectives, supporting the circular economy and reducing emissions wherever possible.”
