Denmark: Switzerland-based Holcim has made an investment in 3D concrete printer supplier COBOD International. Holcim hopes that the investment will help it to further expand its TectorPrint 3D printing ink range. Holcim and COBOD International's collaboration dates to 2019, since which time the partners have 3D printed windmill tower bases in Denmark, a school in Malawi and a housing development in Kenya.

Holcim's head of global research and development, Edelio Bermejo, said “At Holcim, we are continuously expanding our range of building solutions to build better with less, working to improve living standards for all in a sustainable way. 3D concrete printing will help us meet these goals."

India: Finland-based Betolar has launched its first concrete products manufactured using Geoprime on the Indian market. Geoprime is an additive designed for use in cement-free concrete production with ash and ground granulated blast furnace slag (GGBFS). The new concrete product range consists of precast blocks, paving slabs and tiles, and is currently on display at World of Concrete India in Mumbai, Maharashtra.

Betolar's India managing director Abhishek Bhattacharya said "We are happy to introduce our first products to our customers for the Indian markets. We have now moved from laboratory tests into the production phase, and can show concretely how well this solution works. It is great to hear the feedback from the concrete industry in the region to our sustainable solution. Decarbonisation of the concrete industry is a very current and important topic."

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."
