UK: Holcim has acquired recycled concrete and aggregates producer Wiltshire Heavy Building Materials. Wiltshire Heavy Building Materials' material recovery system enables it to process 150,000t/yr of construction and demolition waste for recycling. It operates multiple plants across Wiltshire, Berkshire, Gloucestershire and Oxfordshire, and generated Euro20.6m in sales in 2021.

Switzerland-based Holcim said that the acquisition will expand its UK subsidiary Aggregate Industries' position in the area between London and the West of England, and help the group to achieve its goal of 10Mt/yr-worth of construction and demolition waste recycled globally by 2025.

UK: Denmark-based architecture fund Henrik Frode Obel Foundation has named Seratech as winner of its Obel Award 2022. The award recognises architectural contributions to global development. Seratech has developed an olivine-based composite cement produced using CO₂ from flue emissions, which can sequester double the CO₂ of ordinary Portland cement (OPC). When used as 40% of a blend with OPC, it is able to completely offset the emissions of concrete production.

Team member Barnaby Shanks said "The beauty of the idea is that you can just use it as normal concrete. There are other carbon-neutral materials, but they can be limiting because they can only be precast, cured in a lab in special conditions and shipped elsewhere. We want people to retain the freedom to use concrete the way that they are used to. We don’t want to limit people in any way because we’ll just lessen the amount of impact we can have."

US: Lehigh Hanson has acquired Washington-based concrete and asphalt recycling company JEV Recycling. The Heidelberg Materials subsidiary says that the acquisition strengthens its regional recycled materials portfolio, enabling it to increase its sustainable offering.

President and chief executive officer Chris Ward said “The acquisition of JEV Recycling represents an important step for Lehigh Hanson as we grow our business beyond cement and aggregates while working to lower our environmental footprint. It also highlights the importance of finding innovative ways to serve the growing needs of our customers for responsibly sourced and circular products so they can meet the sustainability targets of their projects.”

Canada: Investment bank BDC Capital has invested US$3.7m in concrete testing technologies supplier Giatec. BDC Capital hopes that the investment will further the development of CO₂-reducing technology and AI-based concrete testing.

Giatec CEO Pouria Ghods said "The BDC Capital investment will propel Giatec's expansion into international markets and accelerate our innovation in CO₂-reducing technology, moving the concrete industry towards carbon neutrality. BDC has a long history of supporting emerging Canadian cleantech firms in their growth through exports, research and development. We at Giatec are looking forward to working with BDC in our mission to revolutionise the concrete industry and to create yet another success story for the BDC cleantech practice.”

Austria: PERI and STRABAG have used a COBOD 3D printer to successfully build Europe’s first 3D printed office building in Hausleiten, Lower Austria.

PERI board member for innovation and marketing Thomas Imbacher said "The building in Hausleiten is a milestone for STRABAG, for PERI, for all involved. We are convinced that 3D printing of buildings will be part of the future of construction, as this technology offers solutions for challenges that are currently occupying our industry: digitalisation, efficiency, shortage of skilled workers and much more."
