Finland: Betolar has signed a letter of intent with Australia-based RISAB and the Vanadium Recovery Project to research the use of slag ‘purified from vanadium’ 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 alternative raw material suppliers.

France: The Scientific and Technical Center for Building (CSTB) has certified Hoffmann Green Cement Technologies’ clinkerless H-UKR alkali-activated slag cement for structural use in buildings of all types. BusinessWire News has reported that the certification confirms the product’s safety, sustainability, lifespan and performance in conformity with Eurocode 2 and Eurocode 8 design standards.

Co-founders Julien Blanchard and David Hoffmann said “In the midst of ongoing frenetic communication regarding carbon neutrality, Hoffmann Green Cement is as usual endeavouring to back its announcements with verified and evaluated elements. The granting of these evaluations further objectifies the quality of our cement, notably with the awarding of a lifespan of 100 years. In this regard, we would like to thank the CSTB’s teams for drafting this unprecedented technical appraisal and our own teams who are working tirelessly on seeking innovative decarbonised solutions to preserve tomorrow’s world.”

Poland: The Building Research Institute has issued environmental product declarations (EPDs) for Cemex Poland’s CEM III slag cement and five other cements produced at its Chełm and Rudniki cement plants and Gdynia grinding plant. The company additionally obtained EPD certification for its Vertua Classic and Vertua Plus concrete products, which contain cement produced using supplementary cementitious materials (SCMs).

Materials director Michał Grys said “For us, product certification is another important step towards sustainable construction and a sustainable future. EPD declarations provide our clients with additional confirmation of the properties of products offered by Cemex Poland. They also improve their chances of obtaining LEED or BREEAM certificates for their investments.”

US: Harsco’s Environmental division has driven its parent group’s revenue in 2021 as services and product demand increased. Its revenue rose by 17% year-on-year to US$1.07bn in 2021 from US$914m in 2020. Its operating income grew by 75% to US$103m from US$59m. Overall group revenue and operating income increased by 20% to US$1.85bn and from a loss of US$3.3m in 2020 to a profit of US$88.4m respectively.

“For the fourth quarter, our businesses continued to benefit from increased environmental solutions demand, and I'm pleased to have met our expectations for the quarter. However, steel volumes slowed through the fourth quarter in some markets, inflation pressures persisted, and labour-market tightness and Omicron impacted productivity. We were able to offset these pressures by controlling our overall spending in the fourth quarter,” said chairman and chief executive officer Nick Grasberger. He added that the group expects to see further improved operating results from its Environmental division in 2022.
