India: Finland-based Betolar introduced its AI-based service for production of reduced-CO2 concrete using its Geoprime additive at World of Concrete India 2023 on 18 October 2023. Betolar designs recipes and provides a liquid chemical dosing system and post-production services to Geoprime users. Dow Jones Institutional News reports that Betolar has concluded strategic tie-ups in South and West India, and is ‘actively planning’ further expansion.
Managing director Abhishek Bhattacharya said "Interest in our solution is growing fast in India and we have successfully demonstrated that the twin goal of sustainability and performance can be achieved remarkably faster with Betolar’s Geoprime solution.”
Denmark: Finland-based Betolar has supplied its Geoprime additive for its maiden construction project in Denmark. Its customer IBF used the additive to produce low-cement paving stones for a 1.5 hectare expansion to the lorry park at the Port of Aalborg. The stones consisted of an 84mm-thick cement-free base made of Geoprime material, with a 6mm-thick cement-based concrete top. The supplier said that the use of Geoprime reduced the project's cement consumption by 90%. This more than halved the carbon footprint of the work.
Betolar's chief commercial officer Ville Voipio said "This shows that the circular economy solution we have developed, which utilises industrial side streams, also works in large construction projects. We have been doing development work with IBF for a long time. Now there is a product on the Danish market that radically cuts emissions compared to traditional products."
Denmark is committed to eliminating 70% of its annual CO2 emissions between 2020 and 2030.
Europe/India: Finland-based Betolar has secured EU-wide and Indian patents for a new waste-based alternative concrete produced without cement and capable of storing energy. Betolar said that the material, which is already patented in Finland, is especially suited for use in renewable energy infrastructure, where it can provide a storage solution for dealing with short-term peaks. Chief commercial officer Ville Voipio said that the company will now seek to establish a partnership for commercialisation of its new alternative building material.
Betolar produces and markets the Geoprime additive used to produce cement-free concrete from supplementary cementitious materials, including ground granulated blast furnace slag (GGBFS), in regions that include India and the EU.
UK: Contractors poured 736m3 of cement-free concrete in an 11-hour continuous pour at the Hurst substation tunnel drive shaft of the London Power Tunnels project on 11 May 2023. Construction Index News has reported that Capital Concrete supplied the concrete. It uses a formula developed by Earth Friendly Concrete to replace 100% of cement with fly ash and ground granulated blast furnace slag (GGBFS) in the presence of an activator and admix solution. The supplier said that the concrete will reduce CO2 emissions by 64% compared with ordinary Portland cement (OPC), corresponding to 111kg/m3 of concrete.
France: Hoffmann Green Cement Technologies has acquired ABC Broyage, which operates a slag grinding plant in North Dordogne. The producer says that ABC Broyage will import granulated blast furnace slag (GBFS) via La Rochelle and supply ground GBFS to its H1 and H2 green cement plants in Bournezeau. This will give Hoffmann Green Cement Technologies self-sufficiency in its raw materials processing.
Co-founders Julien Blanchard and David Hoffmann said “Managing our supply chain has always been one of Hoffmann Green's strategic priorities. After securing our supplies of co-products and their storage, we are now focusing on optimising their processing through the acquisition of ABC Broyage and the development of vertical integration.” Blanchard and Hoffmann noted that, besides strengthening the company’s control over its raw materials supply, ABC Broyage’s slag grinding capacity also secures its margins in the ‘current highly inflationary context.’
