Finland: Betolar has signed a letter of intent with Australia-based RISAB and the Vanadium Recovery Project to research the use of steel slag from which vanadium has been extracted in concrete production. Dow Jones Institutional News has reported that the company says that, through it Geoprime alkali-activated additive technology, the new slag source could replace 10% of the cement used in concrete production in Finland.

CEO Matti Löppönen said "We see a huge opportunity for Betolar here. If successful, we would be able to offer our customers a specific, currently unused slag of the steel industry to replace cement in concrete. Our customers already have experience in utilising other types of slag in the production of concrete using Geoprime. Utilising new side streams will expand the reach of our solution as planned.”

Betolar launched Geoprime in September 2021. It is currently developing a recipe-optimising artificial intelligence (AI) and data platform to bring together concrete producers and suppliers of slag, ash and other materials.

UK: Concrete admixture producer Oscrete UK has appointed Matthew Gabriel to the role of new product development and sustainability manager. The company says that the appointment strengthens its commitment to sustainable construction.

Gabriel said “With the environment at the forefront of everyone’s minds, and customers looking to increase their use of supplementary cementitious materials (SCM), my priority is to develop products and processes which support our customers’ own route towards low carbon concrete.” He continued “Finding cost effective green solutions without impacting performance is key to the future of the construction sector. We are now looking to develop products that can help our customers to use or increase the use of products with a lower eCO₂, hence the creation of a role dedicated entirely to this arena.”
